Animal-human hybrid stickers invading Parisian streets


Suriani-16.jpg

While marketing and mainstream communications campaigns have derived branding inspiration in the comic-like cartoon style of street art, and the values attached to its culture—freedom, community, transgression—the paradox still exists to see it framed and sold through traditional art channels.

We caught up with street artist Rafael Suriani at his recent show, "Collages Urbains", at Cabinet d'amateur gallery in Paris, where he told us more about street art and his relationship with the medium.

Suriani's mark features animals, surviving and thriving in the streets for its powerful and highly recognizable aesthetic. In his half-human-half-animal figures, the animal faces act as liberating masks, allowing the artist to express social criticism in an elegant way. The vibrant, seemingly playful creatures refrain from getting too serious and maintain a suggestive tone that avoids the obvious.

The stickers are the result of a double-binding process that first assembles man and animal, then adheres the resulting figure to the wall. In the past, Suriani has drawn from his Latin-American heritage, playing with shamanic mythology figures such as toucan or jaguar. In his recent series, on the other hand, he is more interested in urban domestic animals such as cats and dogs—according to the artist, the convention that they tend to resemble their owners offers a metaphoric way to talk about us people. Recently Suriani made a series of French "Bulldogs" as a special dedication on London walls, using this breed to cartoon and make fun of some French characteristics. Each dog expresses a different state of mind—humor, spirituality, criticism or beauty.

Suriani uses the rare technique of hand-painting every poster he sticks on the streets. Making each sticker is the result of a process involving selecting photos from the Internet, cutting them in Photoshop, then screening and painting before cutting the final product. Such repetition lies at the heart of street art practice, which is often based on plastering as many spots as possible, invasion-style.

Suriani-17.jpg

When considering the ephemeral fate of the piece of work destined for degradation of the elements, police destruction or theft from passers-by, the time and effort for such little reward seems remarkable. Suriani explains, however, that the fleeting nature of his work is freeing and allows him to be audacious with both subject and technique. To him, because there is no pressure or constraint, that achievement is rarely a failure.

Suriani-11.jpg

In the end, the piece of art is not the only sticker by itself, it is the sticker in its context, seen as a whole on the wall with the daylight shining on it, the motorbikes parked against it or the branch of a tree creeping across. Rarely is the work's time spent on the wall its only life, after all, with the rise of dedicated photographers immortalizing the scenes for the Internet.

Suriani-7.jpg

Suriani claims his intention to step into the city's landscape by bringing much-needed beauty comes with a positive message. Rather than being aggressive or controversial, Suriani takes pleasure in having people on the street enjoy his figures. His work is bound to the city—physically, geographically and socially—compelling the public to refresh their view of their surroundings and drawing their eyes to the places that typically go unnoticed. As an architect, Suriani has found a way to unveil the city and change people's perception of the scenes they see everyday without truly seeing them. The choice of venue is very important, based on aesthetic consideration with attention to the context and surroundings like the location.

EURO 2012 POSTERS BY DAVID WATSON

Euro 2012 Posters by David Watson

Euro 2012 recently began and, for those of you who don’t know, it’s the European football championship. European football is what we Americans call soccer, and it has slowly gained steam over the years, although still not as popular as American football…  Whether you’re into the championship or not (or even sports in general), you’ll probably love these simple, modern posters David Watson ofTrebleseven designed for it.

 Euro 2012 Posters by David Watson

Each poster represents a particular country that’s playing, and the colors of their flag are incorporated into one of the various circular designs. I love the typographic twist these posters have and how they don’t have blatant sports references in them.

American street artist Frank Shepard Fairey works on his latest piece, Envision, above a shop in Turnpike Lane

American street artist Frank Shepard Fairey

The natural territory of the street artist Shepard Fairey would seem to be as all-American as it gets. Emerging from the country's skateboarding scene he achieved global prominence with his much copied, much parodied Hope poster displaying a stylised Barack Obama in shades of blue and red.

He spent much of Friday assembling his latest street mural in a seemingly less likely locale – a suburban street in Turnpike Lane, one of north London's more economically mixed neighbourhoods.

Hoisted aloft by a rented cherry picker, the 42-year-old artist used stencils and paint to create Envision, an image of a giant, stylised eyeball design, set in the frame of a disused Victorian placard site on the wall of a local shop.

The unlikely public commission, carried out with any charge by the artist, was the almost accidental result of a wider community regeneration programme carried out by the local council, Haringey, and the green travel charity Sustrans.

In getting together to decide options for more pedestrian-friendly street layouts, locals pondered what to do with the crumbling and slightly tatty shop wall, and decided the existing frame left by the long-disappeared Victorian placard would be best filled by a mural.

James Straffon, a local who helped organise the project, went to a London art gallery specialising in graffiti artists to seek help.

He said: "The woman from the gallery asked: 'Ideally, who would you like?' I said: 'I know it would never happen, but Shepard Fairy.' She said: 'Shall I get in touch with him, then?' I stuck my neck out and said yes and sent them a diagram with the sizes, thinking nothing would happen. Literally a week later they said, he's interested and he's coming over."

Straffon says he remains unsure why such a celebrated artist would be interested in a relatively out-of-the-way location. He said: "I think what sold it was that it's an old Victorian billboard. I think they like the fact it's the old London thing."

Before Fairey arrived, Straffon and some neighbours spent a day preparing the wall, painting it in a specified shade of red for a background to the stencilled design.

The US artist and his team spent several hours in decidedly mixed weather putting the design in place. Straffon said: "He's come from west coast America to dreary, sodden London. He must be thinking: 'Great, I've got to do this.' It's quite windy, too."

Another oddity is that this is Turnpike Lane's second work by a globally-known street artist in a matter of months. Last month, a mural believed to be by Banksy, a rough UK equivalent to Fairey, appeared on the wall of the area's local Poundland shop, showing a child sweatshop worker sewing jubilee bunting.

NOBODY DIED FROM LACK OF SLEEP, AA MYTHs

Beyond leaving you drowsy and irritable, sleepless nights can take aserious toll on your physical and mental health.

"We know sleep is a critical biological function that influences a wide variety of physiological process," said Dr. Susan Redline, a sleep specialist at Brigham and Women's Hospital in Boston. "Sleep deficiency can affect mood and the ability to make memories and learn, but it also affects metabolism, appetite, blood pressure, levels of inflammation in the body and perhaps even the immune response."

Lack of sleep has been linked to stroke, obesity, diabetes, anxiety, depression, and the country's No. 1 killers: heart disease and cancer. Read on to learn the health hazards of sleep deficiency and how you can sleep better.

HEALTH HAZARDS LINKED TO LACK OF SLEEP

Stroke

A new study of more than 5,600 people found those who slept fewer than six hours a night were more likely to suffer a stroke than their well-rested counterparts.

"We speculate that short sleep duration is a precursor to other traditional stroke risk factors, and once these traditional stroke risk factors are present, then perhaps they become stronger risk factors than sleep duration alone," Megan Ruiter of the University of Alabama at Birmingham said in a statement.

The study was presented today at the 26th annual meeting of the Associated Professional Sleep Societies in Boston, Mass.

Stroke risk is also higher in people who are overweight, diabetic or hypertensive -- all conditions linked to poor sleep.

HEALTH HAZARDS LINKED TO LACK OF SLEEP

Obesity and Diabetes

Sporadic and irregular sleep can raise blood sugar levels and slow the body's metabolism,increasing the risk of obesity and diabetes, according to an April 2012 study published in Science Translational Medicine.

"The evidence is clear that getting enough sleep is important for health," said study author Orfeu Buxton, a neuroscientist at Brigham and Women's Hospital in Boston.

Sleep deficiency can also lead to bad food choices, according to a study that found the sight of unhealthy food activated reward centers in the brains of sleep-deprived people.

"The results suggest that, under restricted sleep, individuals will find unhealthy foods highly salient and rewarding, which may lead to greater consumption of those foods," said Marie-Pierre St-Onge from St. Luke's Roosevelt Hospital Center and Columbia University in New York, and lead author of the study presented today at the Associated Professional Sleep Societies in Boston. "Indeed, food intake data from this same study showed that participants ate more overall and consumed more fat after a period of sleep restriction compared to regular sleep."

HEALTH HAZARDS LINKED TO LACK OF SLEEP

Anxiety and Depression

Sure, sleepless nights make for miserable mornings. But chronic sleep deficiency can lead to anxiety and depression -- both serious mood disorders.

"People feel more anxious, restless, irritable, less satisfied," said Dr. Mark Dyken, director of the University of Iowa's Sleep Disorders Center in Iowa City, adding sleep deficiency can impact careers and relationships. "They have difficulty focusing and sometimes feel like they just don't care anymore."

Brain imaging suggests sleep deprivation can boost activity in the brain's emotional centers, according to a study presented today at the Associated Professional Sleep Societies in Boston.

"Our results suggest that just one night of sleep loss significantly alters the optimal functioning of this essential brain process, especially among anxious individuals," study author Andrea Goldstein from the Sleep and Neuroimaging Laboratory at the University of California, Berkeley, said in a statement. "This is perhaps never more relevant considering the continued erosion of sleep time that continues to occur across society."

HEALTH HAZARDS LINKED TO LACK OF SLEEP

Cancer

Sleep deficiency has also been linked to an increased risk of cancer.

A 2008 study published in the British Journal of Cancer found women who slept fewer than six hours a night were more likely develop breast cancer, and a 2010 study published in the journal Cancer found those who slept fewer than six hours a night were more likely to have colorectal polyps, which can lead to colon cancer.

The biological mechanisms are unclear, but lack of sleep has been shown to boost levels of inflammation in the body and interfere with the immune response, both of which have been implicated in cancer.

"Sleep is restorative," said Dyken. "And if you don't get it, your health will suffer."

HEALTH HAZARDS LINKED TO LACK OF SLEEP

Heart Disease

Short and sporadic sleep may also raise the risk of heart disease.

A 2011 study published in the European Heart Journal found people who slept fewer than six hours a night were 48 percent more likely to develop or die from heart disease.

The link could have something to do with levels of inflammation in the body, but the researchers also found higher blood pressure and cholesterol in people with sleep deficiency.

HEALTH HAZARDS LINKED TO LACK OF SLEEP

Get Your Sleep

With hectic work and family schedules, getting a good night's sleep is no easy feat. But experts say a little planning can go a long way, helping you feel refreshed the next morning and for many to come.

"Make sure your bedroom is dark and quiet, and avoid reading anything that's going to make you excited or worried," said Dyken. "Try not to exercise or eat a big meal within three hours of your bedtime, but don't go to bed hungry, either."

Caffeine and alcohol can also interfere with sleep, according to Redline.

"Much of sleep deficiency is self-inflicted," she said. "But adults should do their best to get to bed at regular times and aim to have 7.5 hours on average of sleep. Set your schedule such that you honor and respect your sleep needs."

Man stranded in desert builds motorcycle out of his broken car

Citroen 2CV motorcycleAccording to Merriam-Webster, ingenuity can be defined as "skill or cleverness in devising or combining" or "cleverness or aptness of design or contrivance." We'd say that's an apt description of a Frenchman named Emile who reportedly found himself stranded in the deserts of Northwest Africa after breaking a frame rail and a suspension swingarm underneath his Citroën 2CV.


What to do? Why, disassemble the broken hulk and build yourself a motorcycle from its pile of parts, of course! As the story goes, Emile was able to use the inventive machine to escape the desert, though not before convincing the local authorities that he wasn't an insurgent and paying a fine for importing a non-conforming vehicle...

Since Emile was the only soul in the area, nobody has been able to confirm the veracity of the events that led to the little French runabout's conversion into a makeshift motorcycle. That said, judging by the images you can see here (apparently from the March 2003 issue of 2CV Magazine), this Citroën-bred two-wheeler does indeed exist, and it was definitely fashioned from parts scavenged from an old 2CV.

Emile, wherever you are, we take our hats off to your real-life MacGyver skills, sir.

Greek far-right parties could end up with as much as 20 percent of the vote in Sunday's elections. The neo-Nazi Golden Dawn party has intensified the xenophobic atmosphere in the country.

At night, the streets leading to Omonoia Square are empty. That wasn't always the case. The area was the premier multicultural neighborhood of Athens and one of the first quarters to be gentrified. Jazz bars and Indian restaurants lined the streets, separated by the occasional rooms-by-the-hour hotel. It was a quarter full of immigrants, drug addicts and African prostitutes, but also of journalists, ambitious young artists and teenagers from private schools. Today, the immigrants stay home once night falls. They are afraid of groups belonging to the "angry citizens," a kind of militia that beats up foreigners and claims to help the elderly withdraw money from cash machines without being robbed. Such groups are the product of an initiative started by the neo-Nazi Chrysi Avgi -- Golden Dawn -- the party which has perpetrated pogroms in Agios Panteleimon, another Athens neighborhood with a large immigrant population. There are now three outwardly xenophobic parties in Greece. According to recent surveys, together they could garner up to 20 percent of the vote in elections on Sunday: the anti-Semitic party LAOS stands to win 4 percent; the nationalist party Independent Greeks -- a splinter group of the conservative Nea Dimokratia party -- is forecast to win 11 percent; and the right extremists of Golden Dawn could end up with between 5 and 7 percent. My name is Xenia, the hospitable. Greece itself should really be called Xenia: Tourism, emigration and immigration are important elements of our history. But hospitality is no longer a priority in our country, a fact which the ugly presence of Golden Dawn makes clear. A Personal Attack Shaved heads, military uniforms, Nazi chants, Hitler greetings: How should a Greek journalist deal with such people? Should one just ignore them and leave them unmentioned? Should one denounce them and demand that they be banned? One shouldn't forget that they are violent and have perpetrated several attacks against foreigners and leftists. I thought long and hard about how to write about Golden Dawn so that my article was in no way beneficial to the party. On April 12, the daily Kathimerini ran my story under the headline "Banality of Evil." In the piece, I carefully explained why it was impossible to carry on a dialogue with such people and why I thought the neo-Nazi party should disappear from media coverage and be banned. Five days later, an anonymous reply to my article appeared on the Golden Dawn website. It was a 2,500-word-long personal attack in which the fascists recounted my entire career, mocked my alleged foreign roots (I was born in Hamburg) and even, for no apparent reason, mentioned my 13-year-old daughter. The unnamed authors indirectly threatened me as well: "To put it in the mother tongue of foreign Xenia: 'Kommt Zeit, kommt Rat, kommt Attentat!'" In other words, watch your back. Most Greeks believe that Golden Dawn has connections to both the police and to the country's secret service. Nevertheless, I went to the authorities to ask what I should do. I was told that I should be careful. They told me that party thugs could harass me, beat me or terrorize me over the phone. It would be better, they said, if I stopped writing about them. If I wished to react to the threats, they suggested I file a complaint against Golden Dawn's service provider. That, however, would be difficult given that the domain is based somewhere in the United States. Like Weimar Germany A friend told me that I should avoid wearing headphones on the street so that I can hear what is going on around me. My daughter now has nightmares about being confronted by members of Golden Dawn. Three of her classmates belong to the party. The three boys have posted pictures of party events on their Facebook pages. For their profile image, they have chosen the ancient Greek Meandros symbol, which, in the red-on-black manifestation used by Golden Dawn, resembles a swastika. The group's slogans include "Foreigners Out!" and "The Garbage Should Leave the Country!" The fact that immigration has become such an issue in the worst year of the ongoing economic crisis in the country can be blamed on the two parties in government. The Socialist PASOK and the conservative Nea Dimokratia (New Democracy, or ND) are running xenophobic campaigns. ND has said it intends to repeal a law which grants Greek citizenship to children born in Greece to immigrant parents. And cabinet member Michalis Chrysochoidis, of PASOK, has announced "clean up operations" whereby illegal immigrants are to be rounded up in encampments and then deported. When he recently took a stroll through the center of Athens to collect accolades for his commitment to the cause, some called out to him: "Golden Dawn has cleaned up Athens!" Yet, Chrysochoidis is the best loved PASOK politician in his Athens district, in part because of his xenophobic sentiments. His party comrade, Health Minister Andreas Loverdos, is just as popular. Loverdos has warned Greek men not to sleep with foreign prostitutes for fear of contracting HIV and thus endangering the Greek family. High unemployment of roughly 22 percent, a lack of hope, a tendency toward violence and the search for scapegoats: Analyses in the Greek press compare today's Greece with Germany at the end of the Weimar Republic. "We didn't know," said many Germans when confronted with the truth of the Holocaust after Nazi rule came to an end. After elections on May 6, no Greeks should be able to make the same claim.

Locked Up Abroad is different.

Reality TV is, at its core, about letting viewers revel in the bad decision-making of others: those who speak without thinking, who backstab, who have sex without condoms, who cheat. Frustratingly, though, reality shows—to which I am unapologetically addicted—tend to reward bad behavior, by giving its villains notoriety, spinoffs, opportunities to endorse weight-loss products, a nice sideline in paid interviews with supermarket tabloids, and other D-list rewards.

Locked Up Abroad is different. The National Geographic show, the sixth season of which premiered last week, gives its stars something they wouldn’t get on other reality shows: their comeuppance.

Having debuted in the U.K. (under the title Banged Up Abroad), Locked Up Abroad showcases one person (sometimes a couple) who ends up in prison overseas. Participants fit into one of two categories. The first group are the (largely) innocent: the married missionary couple who were kidnapped in the Philippines by the Islamist group Abu Sayyaf, for instance, or the seemingly goodhearted duo who wanted to help children in Chechnya, but ended up held hostage. These tales of the altruistic and naive can be difficult to watch.

But then there are those who rather deserve what happens to them. Typically these are drug smugglers, and their episodes follow a familiar arc. A young person—they’re almost always young—is bored or in need of cash (usually both). She is desperate or feels invincible (usually both). Someone approaches her and offers a seemingly great deal: an all-expenses-paid, luxurious overseas trip in exchange for a small favor. Sometimes the would-be employer is upfront and admits he needs a drug mule, but downplays the risk; other times, he hints at harmless-sounding illegalities, like bringing back legal goods to beat the export tax. In a few cases, the cover story is painfully thin: Come with me to check out this cool new nail polish technology only available in Thailand, for example. (That woman was in a vulnerable place: She had just been released on bail after killing her partner’s former husband—in self-defense, she claimed.)

The drug smugglers are caught, of course, usually at the airport, and brought to prison. And while a few episodes have taken place in developed countries—Spain, Japan, South Korea—the majority of our anti-heroes end up incarcerated in places with some of the dirtiest and most dangerous penitentiaries in the world.

Take last week’s episode, “From Hollywood to Hell.” (And pardon my spoilers, but this installment is too good not to describe in detail.) In 2001, actor Erik Aude was living the marginal Hollywood dream. An ür-bro, he had played bit parts in Dude, Where’s My Car?(credited as “Musclehead”) and 7th Heaven (“Boyfriend”) when a gym buddy asked him to go to Turkey to bring back “leather goods.” Aude makes the trip, and though a drug-sniffing dog alerts authorities at the Turkish airport, they find nothing—so Aude feels sure the whole thing is legit. He even recommends that one of his brothers start couriering for his friend. Then, when his brother backs out of a planned trip to Pakistan in 2002, Aude steps in, and shit gets real.

It is difficult to feel sorry for Aude. After his escort dumps him in an Islamabad hotel and warns him not to leave because the area is unsafe for Americans, he doesn’t head to the embassy or the airport. Instead, he goes jogging—and even tries to flirt with girls in headscarves on the street (with disastrous results). And when he is taken to the airport with just one suitcase, he is (he claims) not the least bit suspicious that he might be a drug mule. When a customs official asks him whether his trip was for business or pleasure, he cheeses, “Pleasure is my business.”

Aude’s episode is mind-bogglingly watchable, not least because he—of course!—plays himself in the re-enactment. In his telling, he was a virtual action star: On at least three occasions, he single-handedly fights back dozens of Pakistanis. After he takes out a prison bully, he is hailed a hero. He rejects a reduced sentence because it would require him to plead guilty—and his pride is more valuable than his freedom, he says.

Aside from those truly in the wrong place at the wrong time, the most sympathetic characters of Locked Up Abroad may be the embassy employees called in to assist the suspected smugglers. Inevitably, Locked Up Abroad participants are horrified that the embassies of their homelands—usually English-speaking countries like the U.S., the U.K., or Australia—can’t do more for them. I can just imagine U.S. Embassy workers calling “not it” every time they get word from local authorities about some young American knucklehead who thought he could sneak past security with a bag full of cocaine.

Tonight’s episode is called “The Juggler Smuggler,” and its “hero” is Mark Greening, a “party-loving” drug-runner who knows his latest trip is “doomed” when he doesn’t get his fortune told by “his favorite Gypsy woman.” I can’t wait.

Low fare airline bmibaby to close

Low fare carrier bmibaby is set to close later this year, threatening the loss of hundreds of jobs and the ending of its flights. The carrier transferred to International Airlines Group, the owners of British Airways, last month, but consultations have now started with unions about its closure in September. The GMB union said it was "devastating" news, especially for the East Midlands, where hundreds of jobs are now threatened with the axe. With bmi Regional, bmibaby transferred to International Airlines Group ownership on completion of the purchase from Lufthansa. IAG has consistently said that bmibaby and bmi Regional are not part of its long-term plans. A statement said: "Progress has been made with a potential buyer for bmi Regional, but so far this has not been possible for bmibaby, despite attempts over many months by both Lufthansa and IAG. Bmibaby has therefore started consultation to look at future options including, subject to that consultation, a proposal to close in September this year." Peter Simpson, bmi interim managing director, said: "We recognise that these are unsettling times for bmibaby employees, who have worked tirelessly during a long period of uncertainty. Bmibaby has delivered high levels of operational performance and customer service, but has continued to struggle financially, losing more than £100 million in the last four years. In the consultation process, we will need to be realistic about our options. "To help stem losses as quickly as possible and as a preliminary measure, we will be making reductions to bmibaby's flying programme from June. We sincerely apologise to all customers affected and will be providing full refunds and doing all we can with other airlines to mitigate the impact of these changes." Jim McAuslan, general secretary of the pilots' union Balpa, said: "This is bad news for jobs. Bmibaby pilots are disappointed and frustrated that, even though there appears to be potential buyers, we are prevented from speaking with them to explore how we can contribute to developing a successful business plan. "The frustration has now turned to anger following the news that Flybe (which is part owned by BA) has moved onto many of these bmibaby routes without any opportunity for staff to look at options and alternatives. Balpa's priority is to protect jobs; and we will use whatever means we can to do so." The changes mean that all bmibaby flights to and from Belfast will cease from June 11, although this will not affect bmi mainline's services to London Heathrow. Bmibaby services from East Midlands to Amsterdam, Paris, Geneva, Nice, Edinburgh, Glasgow and Newquay, and from Birmingham to Knock and Amsterdam, will end on the same date.

Reopen Madeleine case, police urge

Scotland Yard has urged Portuguese authorities to reopen the search for Madeleine McCann as detectives said there are 195 potential leads to finding her alive. The detective leading the Metropolitan Police review said the case can still be solved before officers released a picture of what she might now look like as a nine-year-old. Detective Chief Inspector Andy Redwood said he believes her disappearance was a stranger abduction, as he said there are 195 "investigative opportunities". Police refused to say what evidence they had uncovered to suggest Madeleine is alive. Mr Redwood confirmed that his team of more than 30 officers involved in the case had been out to Portugal seven times, including a visit to the family's holiday flat in Praia da Luz. It will be five years ago next week since the three-year-old went missing as her parents, Kate and Gerry McCann, dined with friends nearby. A spokesman for the McCanns said the family was pleased with the image. Mr Redwood said his 37 officers had dealt with 40,000 pieces of information but the "primacy still sits in Portugal" in the attempt to find her. Commander Simon Foy said: "Most significantly, the message we want to bring to you is that, on the evidence, there is a possibility that she is alive and we desperately need your help today to appeal directly to the public for information to support our investigation." Mr Redwood said "evidence that she is alive stems from the forensic view of the timeline" that there was the opportunity for her to be taken. Investigations show "there do appear to be gaps", he added. Detectives in Portugal are also understood to want the case reopened but must gain judicial approval via the courts.

Insecure websites to be named and shamed after checks

Companies that do not do enough to keep their websites secure are to be named and shamed to help improve security. The list of good and bad sites will be published regularly by the non-profit Trustworthy Internet Movement (TIM). A survey carried out to launch the group found that more than 52% of sites tested were using versions of security protocols known to be compromised. The group will test websites to see how well they have implemented basic security software. Security fundamentals The group has been set up by security experts and entrepreneurs frustrated by the slow pace of improvements in online safety. "We want to stimulate some initiatives and get something done," said TIM's founder Philippe Courtot, serial entrepreneur and chief executive of security firm Qualys. He has bankrolled the group with his own money. TIM has initially focused on a widely used technology known as the Secure Sockets Layer (SSL). Experts recruited to help with the initiative include SSL's inventor Dr Taher Elgamal; "white hat" hacker Moxie Marlinspike who has written extensively about attacking the protocol; and Michael Barrett, chief security officer at Paypal. Continue reading the main story “ Start Quote Everyone is now going to be able to see who has a good grade and who has a bad grade” Philippe Courtot Many websites use SSL to encrypt communications between them and their users. It is used to protect credit card numbers and other valuable data as it travels across the web. "SSL is one of the fundamental parts of the internet," said Mr Courtot. "It's what makes it trustworthy and right now it's not as secure as you think." Compromised certificates TIM plans a two-pronged attack on SSL. The first part would be to run automated tools against websites to test how well they had implemented SSL, said Mr Courtot. "We'll be making it public," he added. "Everyone is now going to be able to see who has a good grade and who has a bad grade." Early tests suggest that about 52% of sites checked ran a version of SSL known to be compromised. Companies who have done a bad job will be encouraged to improve and upgrade their implementations so it gets safer to use those sites. The second part of the initiative concerns the running of the bodies, known as certificate authorities, which guarantee that a website is what it claims to be. TIM said it would work with governments, industry bodies and companies to check that CAs are well run and had not been compromised. "It's a much more complex problem," said Mr Courtot. In 2011, two certificate authorities, DigiNotar and GlobalSign were found to have been compromised. In some cases this meant attackers eavesdropped on what should have been a secure communications channel. Steve Durbin, global vice president of the Information Security Forum which represents security specialists working in large corporations, said many of its members took responsibility for making sure sites were secure. "You cannot just say 'buyer beware'," he said. "That's not good enough anymore. They have a real a duty of care." He said corporations were also increasingly conscious of their reputation for providing safe and secure services to customers. Data breaches, hack attacks and poor security were all likely to hit share prices and could mean they lose customers, he noted.

Anti-depressants likely do more harm than good, study suggests

Commonly prescribed anti-depressants appear to be doing patients more harm than good, say researchers who have published a paper examining the impact of the medications on the entire body. See Also: Health & Medicine Pharmacology Birth Defects Mental Health Research Mind & Brain Depression Disorders and Syndromes Psychiatry Reference COX-2 inhibitor Psychoactive drug Seasonal affective disorder Anti-obesity drug "We need to be much more cautious about the widespread use of these drugs," says Paul Andrews, an evolutionary biologist at McMaster University and lead author of the article, published recently in the online journal Frontiers in Psychology. "It's important because millions of people are prescribed anti-depressants each year, and the conventional wisdom about these drugs is that they're safe and effective." Andrews and his colleagues examined previous patient studies into the effects of anti-depressants and determined that the benefits of most anti-depressants, even taken at their best, compare poorly to the risks, which include premature death in elderly patients. Anti-depressants are designed to relieve the symptoms of depression by increasing the levels of serotonin in the brain, where it regulates mood. The vast majority of serotonin that the body produces, though, is used for other purposes, including digestion, forming blood clots at wound sites, reproduction and development. What the researchers found is that anti-depressants have negative health effects on all processes normally regulated by serotonin. The findings include these elevated risks: developmental problems in infants problems with sexual stimulation and function and sperm development in adults digestive problems such as diarrhea, constipation, indigestion and bloating abnormal bleeding and stroke in the elderly The authors reviewed three recent studies showing that elderly anti-depressant users are more likely to die than non-users, even after taking other important variables into account. The higher death rates indicate that the overall effect of these drugs on the body is more harmful than beneficial. "Serotonin is an ancient chemical. It's intimately regulating many different processes, and when you interfere with these things you can expect, from an evolutionary perspective, that it's going to cause some harm," Andrews says. Millions of people are prescribed anti-depressants every year, and while the conclusions may seem surprising, Andrews says much of the evidence has long been apparent and available. "The thing that's been missing in the debates about anti-depressants is an overall assessment of all these negative effects relative to their potential beneficial effects," he says. "Most of this evidence has been out there for years and nobody has been looking at this basic issue." In previous research, Andrews and his colleagues had questioned the effectiveness of anti-depressants even for their prescribed function, finding that patients were more likely to suffer relapse after going off their medications as their brains worked to re-establish equilibrium. With even the intended function of anti-depressants in question, Andrews says it is important to look critically at their continuing use. "It could change the way we think about such major pharmaceutical drugs," he says. "You've got a minimal benefit, a laundry list of negative effects -- some small, some rare and some not so rare. The issue is: does the list of negative effects outweigh the minimal benefit?"

exploding the common myths about which foods are good for us

Myth: Salt in your diet causes high blood pressure

In the 1940s, Walter Kempner, a researcher at Duke University, North Carolina, became famous for using salt restriction to treat people with high blood pressure. Later, studies confirmed that reducing salt could help reduce hypertension. But you don't have to avoid salt entirely, says Sara Stanner, of the Nutrition Society. "Adults need a small amount of sodium in their diet to maintain the body's fluid balance."

Average salt intakes have come down in recent years, mainly due to product reformulation. But it's still the case that many of us consume too much salt – around 9g a day instead of the maximum recommended dose of 6g per day – around 75 per cent of which is in processed foods such as soups, sauces, sandwiches and processed meat.

"People often think it's really bad to add salt into cooking or on to your plate, but that forms no more than 10 per cent of your total intake," says Stanner. "So you can get people who never have salt at their table, but have a very high salt intake, while others put salt on most meals, but have a lower intake."

Myth: Carbohydrates are bad for you

"Carbohydrate-rich foods are an ideal source of energy. They can also provide a lot of fibre and nutrients," says Sara Stanner. "Potatoes, for instance, are one of the best sources of vitamin C, yet potato consumption in the UK has fallen considerably."

One of the main reasons carbohydrates have fallen out of favour is that they are perceived to be fattening. "Foods high in carbohydrates have had a rough time in the past few years, thanks to the success of low-carb diets, such as the Atkins diet," explains Juliette Kellow.

"But there's no proof that carb-rich foods are more likely to make us gain weight than any other food. Ultimately, it's an excess of calories that makes us pile on the pounds – and it really doesn't matter where those extra calories come from. More often than not, it's the fat we add to carbs that boosts the calorie content, such as butter on toast, creamy sauces with pasta and frying potatoes to make chips."

Myth: Dairy products are fattening and unhealthy

In a study by the Curtin University of Technology in Perth, Australia, slimmers on low- calorie diets which included cheese, yoghurt and milk lost more weight than those on low-dairy diets. Those on the diet including dairy also had the least stomach fat, lower blood pressure and a significantly better chance of avoiding heart disease and diabetes.

Dairy products are packed with essential nutrients that help keep us healthy, says Juliette Kellow. "As well as being good sources of protein, zinc and some B vitamins, dairy products are packed with calcium, a mineral that helps to build strong, healthy bones – and the stronger the bones are, the less likely you'll be to suffer from osteoporosis in later life."

There are loads of low-fat versions of dairy, such as skimmed or semi-skimmed milk, low-fat yoghurts and reduced-fat cheeses, she says – and low-fat versions don't mean less calcium. "Skimmed and semi-skimmed milk actually contain slightly more calcium than full-fat milk."

Myth: Red meat is bad for you

Publishing what it called "the most authoritative ever report of bowel cancer risk" last year, the World Cancer Research Fund recommended that people limit their intake of red meat to 500g a week, or just over a pound in weight. The net result of such studies is always the same – people panic.

But 500g is roughly the equivalent of five or six medium portions of roast beef, lamb or pork. "Red meat is a valuable source of minerals and vitamins, particularly iron, and we know that large numbers of women have such low intakes of this nutrient that they're at risk of anaemia. There's no need for people to think, 'I should be eating fish' when they have a steak,' provided they eat it in moderation," says Sarah Schenker.

Another myth about red meat is that it's high in fat, says Juliette Kellow, dietitian and advisor to Weight Loss Resources. "Thanks to modern breeding programmes and new trimming techniques, red meat is now leaner than ever.

Processed meat of all kinds, however, should be avoided.

Myth: Fresh is always better than frozen

Frozen fruit and vegetables can be more healthy than fresh. "Research shows that freezing vegetables such as peas as soon as they're picked – when they are at their nutritional peak – means they retain higher levels of vitamins, particularly vitamin C," says Sarah Schenker. "Once frozen, the deterioration process stops, locking in goodness. The fresh variety often travel long distances and sit on grocery shelves and along the way, heat, air, water and time can lead to a significant loss of nutrients."

Frozen or canned fruits and vegetables can also be as nutritious as fresh ones, if not more so. Again, they are often packaged within hours of being picked, retaining their nutritional value. "Always check salt and sugar levels though by comparing labels," says Sarah Schenker, of the British Dietitic Association. Even dried fruit can be healthier than fresh. "When you eat dried fruit you usually eat more than the fresh equivalent – for instance six dried apricots instead of three fresh ones. This is more calorific but you get a bigger amount of nutrients," says Schenker.

Myth: Soy eases menopausal problems

For years, the fact that Asian women have fewer menopausal symptoms has been attributed to high levels of soy in their diet. Soy products such as tofu contain natural plant oestrogens and there have been increasing claims that these might help women going through the menopause whose own oestrogen levels are dwindling.

But a University of Miami study has found that soy does nothing to abate hot flushes and bone-density loss. In fact, the women given soy appeared to experience more hot flushes than those given a placebo.

Experts including Dr Malcolm Whitehead, a menopause expert at King's College Hospital in London, aren't surprised. "In my clinical experience, women say this doesn't work for them," he says, adding that HRT is a safe and effective treatment for most women.

Others point to previous studies showing that soy can work, but the British Dietetic Association's Sarah Schenker, says, "This research has always been weak. People got excited about those early small studies, but the more research that was done, the more doubts appeared."

Myth: Brown bread is better for you than white

A darker loaf of bread does not necessarily mean it's made with whole grains – it could simply contain caramel colouring or such a small amount of whole wheat that its nutritional benefits are no different to white bread. "The real health benefits come from eating wholemeal bread instead of white," says Sarah Schenker.

Wholemeal is made from flour containing all the goodness of wheat grains. The outer husk has not been removed, so the resulting bread is much richer in fibre, protein and vitamins B1, B2, niacin, B6, folic acid and biotin. Brown bread, in contrast, is made from finely milled wheat, from which the bran has been extracted.

Look for the words "whole grain" or "100% whole wheat" on packaging and ensure the first ingredient listed is whole wheat, oats, whole rye, whole grain corn, barley, quinoa, buckwheat or brown rice. Seeded bread is even better, since it contains even more vitamins, minerals and healthy fats.

Myth: Everyone needs a lot of protein

Protein is essential for growth and development, but experts agree that most people eat far too much of it. "The Department of Health recommends that protein should make up around 10-15 per cent of your daily diet – that's around 55g for men and 45g for women," dietitian Azmina Govindji says. "Yet, according to the British Nutrition Foundation, men are probably munching their way through an average of 88g and women around 64g."

So what's fuelling this notion that we need so much? "Some diets, such as the Atkins diet, advocate speedy weight loss on cutting the carbs and piling on the proteins", Govindji says.

Another contributory factor is that in the past, it was believed nobody could eat too much protein. In the early 1900s, people were told to eat well over 100g a day and in the 1950s, health-conscious people were encouraged to boost their protein intake. But high protein can put a strain on liver and kidneys and other bodily systems.

police hunt for Michael Brown's missing millions

British police are still trying to trace £18m allegedly stolen by the Liberal Democrats' fugitive donor Michael Brown, who is expected to be extradited to Britain within the next 10 days. Brown, 46, was in a holding cell near Madrid airport on Sunday, having been deported from the Dominican Republic, where he had been on the run from UK authorities for three years. Brown, who gave £2.4m to the Liberal Democrats before the 2005 general election, is not expected to challenge a formal move to extradite him to London which has already been set in motion. He was convicted of theft and false accounting in his absence in Britain in 2008 and sentenced to seven years in jail. Detectives are still trying to trace around £18m of Brown's stolen money, which had been moved between his accounts in the US, Britain and Switzerland, the Guardian understands. Brown was estimated to have stolen more than £60m in a number of frauds. Most of his assets have been accounted for in property deals, a Bentley, a yacht and the private jet once used to fly senior Lib Dems across the UK. However, more than £18m has not yet been accounted for. "The file at Interpol on Brown and his associates remains open," a source told the Guardian. Brown's return will be another embarrassing development in the long-running saga over the Lib Dems' biggest single donation. The party has refused to compensate any of Brown's victims, claiming it received the money in good faith and spent it on the 2005 election campaign. Lib Dem leader Nick Clegg welcomed Brown's return to Britain but said on Sunday that the party would not be returning his donation because the Electoral Commission had concluded the money had been received in good faith. The deputy prime minister, who pointed out that the donation was made before he was elected to Westminster, told BBC1's Sunday Politics: "I'm very pleased he's coming back to serve his sentence. This is a convicted fraudster. "I should stress that this is something which happened as far as the Liberal Democrats are concerned before I was even an MP, yet alone leader of the Liberal Democrats. What I've been told is that the Electoral Commission in 2009 looked at this exhaustively – as far as the receipt of that money by the Liberal Democrats from one of his companies. They categorically concluded that the money was received in good faith and all the controls, all the checks that should have been made were reasonably made by the Liberal Democrats at the time. If we'd been shown wanting on those accounts then of course we should pay the money back." But Brown's return will increase focus on the Electoral Commission inquiry into Brown's donations. The inquiry failed to call the Lib Dems' former treasurer, Reg Clark, who resigned over Brown in 2005 and warned advisers to the former Lib Dem leader Charles Kennedy that Brown should be treated with extreme caution. One of Brown's victims said the Lib Dems should return the money. Tony Brown, managing partner at law firm Bivonas which represents US attorney Robert Mann who lost more than $5m (£3m), said Brown may be asked to give evidence as part of his client's claim against the Lib Dems. "The Lib Dems have refused to repay this money to our client even though they know that this is the proceeds of crime. The Electoral Commission has failed to investigate this properly in our view. So now that Brown is returning to the jurisdiction, we can investigate again and establish the basis on which the Lib Dems received this money." Brown is expected to appear before a Spanish court to confirm his name and will then appear before an extradition hearing within 10 days. City of London police, who first uncovered Brown's fraud, confirmed his deportation. Detective Superintendent Bob Wishart said: "We hope that him facing justice will bring some closure to the victims who suffered as a result of his frauds." A close friend of Brown's told the Guardian on Sunday that he had arrived in Spain on Saturday after "volunteering" for deportation from the Dominican Republic, where he has been hiding for three years under the name of Darren Nally. "He asked to return to Britain. He is going home to face the music," the friend said. Brown appeared to come from nowhere when the party was paid £2.4m in the runup to the 2005 election from his company 5th Avenue Partners. A fast-talking and brash Glaswegian, he had walked into the party's then headquarters in Cowley Street and offered it money. He was not registered to vote, had no interest in politics and had never been a party member, but said he was giving the money to create an even playing field. Brown wined and dined with Charles Kennedy and other party grandees, and used his private jet to fly Kennedy across the country during the election campaign. Former Lib Dem insiders say he dazzled them with stories of Gordonstoun public school, St Andrews University and his connections with royalty and the US government. The truth was that he had attended his local school and completed a City and Guilds in catering at Glasgow College of Food Technology. He had no US government links – although he was wanted in Florida for cheque fraud. He was arrested in late 2005 after four former clients said he had duped them out of more than £40m in a high-yield fraud. His victims included Martin Edwards, the former Manchester United chairman, who had invested £8m with 5th Avenue Partners. The court would later be told that 5th Avenue Partners was wholly fraudulent and Brown had given money to the Lib Dems to give himself an air of respectability while duping his victims. The party had been used as part of his cover story, a judge said. In June 2008, while awaiting trial, Brown fled and a warrant was issued for his arrest. In the weeks before he disappeared, from his Hampstead bail address in north London, he changed his name on the electoral roll to Campbell-Brown and allowed his hair to turn grey. He travelled to the Dominican Republic where he enjoyed a millionaire's lifestyle while on the run. He lived in gated communities yards from some of the most pristine beaches in the Caribbean, drove a series of 4x4 vehicles and was a regular at exclusive golf courses. In Punta Cana, an exclusive resort on the eastern tip of the island, he could often be seen walking his dog – named Charles, after the former Lib Dem leader. He was arrested in Punta Cana in January on unrelated fraud allegations.

Donaldson enjoyed a lavish lifestyle in Marbella and Tenerife, trafficking accused found hiding in loft with £70k in cash

 A SUSPECTED drug trafficker was found by police hiding in a farmhouse loft in Scotland with a bag stuffed with £70,000, a Spanish court was told last week. Ian Donaldson, 32, is accused of helping fund an international drugs ring smuggling cocaine and speed from Spain to Scotland The former amateur racing driver – who drove a Lamborghini with the distinctive Lambo 88 plate – was tracked down to the farm by officers from the Scottish Crime and Drugs Enforcement Agency. Donaldson – who enjoyed a lavish lifestyle in Marbella and Tenerife– is one of six Brits facing court in Madrid accused of making millions from the drugs trade. Detective Inspector James Wallace of the SCDEA told the court: “I arrested him on February 27, 2009. He was hiding in a loft area in a farm building. We also found £70,000 hidden in a bag.” Eight SCDEA detectives gave evidence to the National Court in the Spanish capital last week via a video link from Edinburgh. The court heard Scottish police mounted a surveillance operation after Donaldson, from Renton, Dunbartonshire, was released on bail. Detectives watched him in a series of meetings in Glasgow and Hamilton in April 2009, as he tried to hide the origins of his fortune, prosecutors allege. Donaldson met with fellow accused Mary Hendry and Joseph Campbell and was observed discussing large sums of money and swapping paperwork for a nightclub in Gran Canaria. It was alleged they were secretly plotting to make it look like Donaldson had made some of his wealth from the club. Meetings took place at supermarkets in Glasgow and Hamilton and the Mitchell Library in Glasgow. DI Wallace told the court: “We saw he (Donaldson) was creating a defence for the Spanish charges. “I believe they (Hendry and Campbell) were both subservient to Donaldson, who instructed them on what to do.” The detective said Donaldson and his company IRD Services were also investigated for money- laundering in Scotland. He added: “There is evidence he purchased seven vehicles in Scotland, worth up to £900,000, between 2006 and 2008.” Mary Hendry told the court she only met Donaldson twice for legitimate business meetings. She said: “Joseph Campbell introduced me to Ian Donaldson because I was trying to sell my restaurant. “I met him the next day and he said he was not interested. I never saw him again.” It is alleged Donaldson was the money man for a gang of drug smugglers based in Tenerife and Marbella, led by Glaswegian Ronald O’Dea, 45. The gang are alleged to have spent millions on luxury villas, fast cars and yachts. In October 2008, police seized a a haul of amphetamines worth £660,000 heading to Scotland after stopping a lorry in Oxfordshire. Donaldson, Hendry and O’Dea share the dock in Madrid with fellow Scot James MacDonald, 62, and Londoners Steve Brown, 45, and Deborah Learmouth, 49. The gang face charges ranging from drug-trafficking to money-laundering. They deny all charges. Two other defendants – Brian Rawlings and Joseph Campbell – failed to show up at the trial. The judges will give their verdict at a later date.

Wayne Rooney launches phone-hacking claim

Wayne Rooney and England rugby union World Cup winner Matt Dawson are among the new wave of high-profile figures suing Rupert Murdoch's News International over alleged News of the World phone hacking. The England and Manchester United football star, his agent Paul Stretford, Dawson, now a BBC rugby commentator and Question of Sport team captain, actor James Nesbitt and Sir John Major's former daughter-in-law, Emma Noble, are among 46 new phone-hacking cases filed at the high court in London. Times Newspapers, the News International subsidiary that publishes the Times and Sunday Times, is also facing its first civil damages claim, from Northern Ireland human rights campaigner Jane Winter, who is also suing NoW publisher, News Group Newspapers. Winter's claim is related to an article in the Sunday Times in August 2006, her solicitor confirmed. A reference to the article was made in a witness statement she submitted to the Leveson inquiry in February. Winter alleged in evidence to the inquiry that her emails to the former British army intelligence officer Ian Hurst were hacked by NoW. A News International spokeswoman said Winter's case would be "defended vigorously". Others who have filed claims in the past few days seeking damages for alleged invasion of privacy from News Group, the News International subsidiary that published the now-closed Sunday tabloid, include former Conservative cabinet minister and chief whip Lord Blencathra and former Fire Brigades Union general secretary Andy Gilchrist. The list of new claimants also features Michelle Bayford, the former girlfriend of the victim of the 2006 so-called "elephant man" drug trial case. Her then boyfriend, Ryan Wilson, spent three weeks in a coma and lost all his toes and parts of his fingers to gangrene. Another claimant, Anne Colvin, was a witness in the Tommy Sheridan perjury trial. At a case management conference at the high court in London , Hugh Tomlinson QC, representing victims of alleged phone hacking, told Mr Justice Vos that he had 44 new cases filed while two others had submitted their claims via another legal representative. The court also heard that law firm Harbottle & Lewis has a number of "sensitive clients" who wish to remain anonymous. It is expected that up to 200 new claims will be filed over the coming months, Tomlinson told the court in a previous hearing. Claims filed in the past week bring the number of new cases against News International to 46. This figure includes earlier claims filed by public figures including Cherie Booth, Alex Best, the former wife of the late footballer George Best, and Colin Stagg, the man wrongly accused of murdering Rachel Nickell. Others who have filed claims include comedian Bobby Davro, actor Tina Hobley's former husband Steve Wallington, TV personalities Jamie Theakston and Jeff Brazier, the former boxer Chris Eubank, and footballers Peter Crouch, Kieron Dyer and Jermaine Jenas. The cases are part of a second wave of civil actions which Vos is managing following the settlement of more than 50 cases earlier this year including claims by Jude Law, Charlotte Church and Lord Prescott. Tomlinson did not disclose the names of the claimants on Friday, but court documents show that new cases submitted to the high court in the past week bring the number of new actions faced by News International to nearly 50, a number that is expected to rise considerably. Tomlinson told the court that News International had received 100 requests for discovery of preliminary disclosure. He said there were 4,791 potential phone-hacking victims, of which 1,892 had been contacted by the police. The police believed 1,174 were "likely victims". Court 30 in the Rolls Building of the high court was packed, with more than 50 law firms acting for victims. Vos said there were 58 firms of solicitors representing only 100 victims, which he told Tomlinson was "unbelievable". The judge added that he wanted to ensure costs are reduced for claimants. "Many of them have seen the light and have instructed lawyers who have specialist knowledge of this case," said Vos. He suggested possible tariffs of costs for each element of the legal action. This would mean fresh claimants could access to information relating to the News of the World's phone-hacking activity already produced on discovery in earlier cases, without incurring the costs associated with a full action. "I will have no sympathy for outrageous cost estimates," he said. "A claimant is entitled to have a solicitor, but what he is not entitled to have is a solicitor who knows nothing about the case and charges the defendant for that."

What cannabis actually does to your brain

Archaeologists recently found a 2,700-year-old pot stash, so we know humans have been smoking weed for thousands of years. But it was only about 20 years ago that neuroscientists began to understand how it affects our brains.

Scientists have known for a while that the active ingredient in cannabis was a chemical called delta-9-tetrahydrocannabinol, or THC for short. Ingesting or smoking THC has a wide range of effects, from the psychoactive "getting high" to the physiological relief of pain and swelling. It also acts as both a stimulant and depressant. How could one substance do all that?

What cannabis actually does to your brainMeet the cannabinoid receptor

In the 1980s and 90s, researchers identified cannabinoid receptors, long, ropy proteins that weave themselves into the surfaces of our cells and process THC. They also process other chemicals, many of them naturally occurring in our bodies. Once we'd discovered these receptors, we knew exactly where THC was being processed in our bodies and brains, as well as what physical systems it was affecting. Scattered throughout the body, cannabinoid receptors come in two varieties, called CB1 and CB2 - most of your CB1 receptors are in your brain, and are responsible for that "high" feeling when you smoke pot. CB2 receptors, often associated with the immune system, are found all over the body. THC interacts with both, which is why the drug gives you the giggles and also (when interacting with the immune system) reduces swelling and pain.

 

Cannabinoid receptors evolved in sea squirts about 500 million years ago; humans and many other creatures inherited ours from a distant ancestor we share with these simple sea creatures. THC binds to receptors in animals as well as humans, with similar effects.

Tasty, tasty, tasty

Cannabis notoriously makes people hungry - even cancer patients who had lost all desire to eat.One study showed that cancer patients who thought food smelled and tasted awful suddenly regained an ability to appreciate food odors after ingesting a THC compound. There are CB1 receptors in your hypothalamus, a part of your brain known to regulate appetite, and your body's own cannabinoids usually send the "I'm hungry" message to them. But when you ingest THC, you artificially boost the amount of cannabinoids sending that message to your hypothalamus, which is why you get the munchies.

Understanding this process has actually led to a new body of research into safe diet drugs that would block those cannabinoid receptors. That way, your hypothalamus wouldn't receive signals from your body telling it to eat, and would reduce hunger cravings in dieters.

What you're forgetting

What's happening in your brain when smoking pot makes you forget what you're saying in the middle of saying it? According to the book Marijuana and Medicine (National Academies Press):

One of the primary effects of marijuana in humans is disruption of short-term memory. That is consistent with the abundance of CB1 receptors in the hippocampus, the brain region most closely associated with memory. The effects of THC resemble a temporary hippocampal lesion.

That's right - smoking a joint creates the effect of temporary brain damage.

What happens is that THC shuts down a lot of the normal neuroprocessing that goes on in your hippocampus, slowing down the memory process. So memories while stoned are often jumpy, as if parts are missing. That's because parts literally are missing: Basically you are saving a lot less information to your memory. It's not that you've quickly forgotten what's happened. You never remembered it at all.

What cannabis actually does to your brainA bit of the old timey wimey

Cannabis also distorts your sense of time. THC affects your brain's dopamine system, creating a stimulant effect. People who are stoned often report feeling excited, anxious, or energetic as a result. Like other stimulants, this affects people's sense of time. Things seem to pass quickly because the brain's clock is sped up. At the same time, as we discussed earlier (if you can remember), the drug slows down your ability to remember things. That's because it interferes with the brain's acetylcholine system, which is part of what helps you store those memories in your hippocampus. You can see that system's pathway through the brain in red in the illustration at left.

In an article io9 published last year about the neuroscience of time, we noted:

The interesting thing about smoking pot is that marijuana is one of those rare drugs that seems to interact with both the dopamine and the acetylcholine system, speeding up the former and slowing down the latter. That's why when you get stoned, your heart races but your memory sucks.

It's almost as if time is speeding up and slowing down at the same time.

Addiction and medicine

Some experts call cannabis a public health menace that's addictive and destroys lives by robbing people of ambition. Other experts call it a cure for everything from insomnia to glaucoma, and advocate its use as a medicine. The former want it to be illegal; the latter want it prescribed by doctors. Still other groups think it should be treated like other intoxicants such as alcohol and coffee - bad if you become dependent on it, but useful and just plain fun in other situations.

What's the truth? Scientists have proven that cannabis does have medical usefulness, and the more we learn the more intriguing these discoveries become. Since the early 1980s, medical researchers have published about how cannabis relieves pressure in the eye, thus easing the symptoms of glaucoma, a disease that causes blindness. THC is also "neuroprotective," meaning in essence that it prevents brain damage. Some studies have suggested that cannabis could mitigate the effects of Alzheimer's for this reason.

At the same time, we know that THC interferes with memory, and it's still uncertain what kinds of long-term effects the drug could have on memory functioning. No one has been able to prove definitively that it does or does not erode memory strength over time. Obviously, smoking it could cause lung damage. And, like the legal intoxicant alcohol, cannabis can become addictive.

Should cannabis be illegal, while alcohol flows? Unfortunately that's not the kind of question that science can answer. Let's leave the moral questions to courts, policymakers and shamans. I'll be off to the side, smoking a joint, thinking about my acetylcholine system and the many uses of the hippocampus.

France and Germany want to suspend the Shengen Agreement

They say they want a temporary suspension while the crisis continues. Spain will being introducing border restrictions during the European Central Bank meeting in Barcelona at the start of May.Angela Merkel and Nicolás Sarkozy - The Interior Ministers of France and Germany have written a joint letter in which they call for the reform of, and ‘temporary suspension’ of the Schengen agreement which allows for the free movement between most member states of the EU. They say the change is necessary ‘to control the massive flow of immigrants’. The call comes just ahead of the 25th anniversary of the treaty this coming Monday, although many countries signed up in March 1995. France and Germany consider that a ‘temporary suspension’ is needed during the crisis, and Paris and Berlin speak of ‘provisional’ closure of frontiers, and only when a country in the Schengen space cannot control the flow of immigrants. They say they will give the details to their European partners at the next conference. Meanwhile Spain has announced the suspension of the Schengen Treaty and the re-establishing of frontier controls with France ahead of the European Central Bank meeting which is to be held in Barcelona on May 3. It has not yet been decided how long the border restriction will remain in place, but say it will allow the authorities to act if there is ‘a serious threat to public order or interior security’. The measure will only affect the frontiers between Spain and France from the Basque Country to Cataluña. Reports indicate that it was the Catalan Government to step up the controls in the face of possible disturbances and the arrival of anti-system protestors from other countries in Europe.

British police arrested three people, including the royal editor of Rupert Murdoch's Sun tabloid

British police arrested three people, including the royal editor of Rupert Murdoch's Sun tabloid, a source familiar with the situation said, in an escalation of a long-running phone hacking scandal which reaches into Britain's political establishment.

Thursday's arrests and the fact they stemmed from information given to the police by Murdoch's company itself is likely to reignite tensions within the media group, just days before parliament gives its verdict on how the culture of illegality came about.

Next week Rupert Murdoch and son James will also appear before a judicial inquiry to answer questions over the conduct of the press, which will focus on the close ties between Murdoch, his executives and the political establishment.

James Murdoch will appear in court room 73 at the Royal Courts of Justice on Tuesday while lawyers at the inquiry have cleared a day and a half to grill the 81-year-old Rupert on Wednesday and Thursday.

"This was always going to be an important six weeks in this affair, with the Murdochs and politicians going before the Leveson judicial inquiry, but it will be exacerbated by the arrests and the imminent committee report," said Steven Barnett, communications professor at the University of Westminster.

Police made the arrests one day after prosecutors confirmed they had started to examine the police case against four journalists and seven others to establish whether they should be charged with a range of offences including perverting the course of justice.

Press reports have speculated that one of those named in the files is Rebekah Brooks, a former editor of the News of the World and Sun tabloids and a close friend of both Murdochs and Prime Minister David Cameron.

Brooks has been arrested twice, once for corruption and intercepting communications, and more recently for perverting the course of justice, along with her husband, Charlie Brooks.

The three arrested on Thursday were detained at dawn and questioned over inappropriate payments made to police and public officials.

The source familiar with the situation said one of those was Duncan Larcombe, royal editor and a former defence correspondent at the Sun, Britain's biggest selling daily newspaper.

A spokeswoman for Murdoch's British newspaper arm News International confirmed that one of those arrested was a Sun journalist but declined to give further details.

Larcombe was previously a defence correspondent at the Sun and another person arrested on Thursday was described by police as a 42-year-old former member of the armed forces. A woman aged 38 has also been arrested on suspicion of aiding and abetting misconduct in a public office.

ROUTINE HACKING

Murdoch's British newspaper arm has been rocked in the last year by allegations that journalists at the Sun's sister title, the News of the World, had routinely hacked into phones to generate salacious front-page stories.

The police investigation, which forced the closure of the 168-year-old News of the World, has since moved on to the Sun newspaper and whether its journalists paid police and public officials for stories.

While damaging the reputation of Murdoch, the intense spotlight has also revealed the extremely close links he and his executives have with politicians and senior police officers, embarrassing many with tales of horse rides and Christmas drinks between the upper echelons of Murdoch executives and politicians.

Police said the latest arrests were prompted by information provided by the Management and Standards Committee, a small team set up by Murdoch's News Corp to co-operate closely with the police in a move that has infuriated newspaper staff.

The 81-year-old Murdoch was forced to travel to London in February to reassure journalists of his commitment to the Sun after a string of earlier arrests caused a showdown at the paper by staff who felt they had been abandoned by their management.

Since then, the Sun has launched a Sunday version and both the Sun and Murdoch's Times newspaper have noticeably hardened their position towards the government, which turned on Murdoch at the height of the hacking scandal last year.

That antagonism is likely to be exacerbated in the coming weeks when the parliamentary select committee, which summoned James and Rupert Murdoch at the height of the scandal last year, publishes its findings.

The committee investigated allegations of phone hacking after they first surfaced in 2006 and it has since looked at whether it was misled in its initial inquiry by a host of News International executives who pleaded innocence.

Paul Farrelly, a leading member of the committee, told Reuters they hoped to publish the long-awaited report by May 1.

Tom Watson, a member of the committee who has campaigned against Murdoch, told reporters he thought News Corp had become a toxic institution which operated like a shadow state

Phone data shows romance 'driven by women'

 

A study of mobile phone calls suggests that women call their spouse more than any other person. That changes as their daughters become old enough to have children, after which they become the most important person in their lives. The study has been published in the journal Scientific Reports. It also shows that men call their spouse most often for the first seven years of their relationship. They then shift their focus to other friends. The results come from an analysis of the texts of mobile phone calls of three million people. According to the study's co-author, Professor Robin Dunbar of Oxford University, UK, the investigation shows that pair-bonding is much more important to women than men. "It's the first really strong evidence that romantic relationships are driven by women," he told BBC News. "It's they who make the decision and once they have made their mind up, they just go for the poor bloke until he keels over and gives in!" But the data shows that women start to switch the preference of their best friend from about the mid-30s, and by the age of 45 a woman of a generation younger becomes the "new best friend", according to Professor Dunbar. Continue reading the main story “ Start Quote Human societies are moving back to a matriarchy” Prof Robin Dunbar Oxford University "What seems to happen is that women push the 'old man' out to become their second best friend, and he gets called much less often and all her attention is focussed on her daughters just at the point at which you are likely to see grandchildren arriving," he says. Prof Dunbar also claims that the findings suggest that human societies are moving away from a patriarchy back to a matriarchy. The aim of the project was to find out how close, intimate relationships vary over a lifetime. This kind of anthropological study is normally very difficult to do because it is hard for researchers to get such a big picture of people's lives. But by looking at an at an extremely large mobile phone database, they were able to track these changes extremely accurately. They had access to the age and sex of the callers, who between them made three billion calls and half a billion texts over a period of seven months. Intensely focussed The team wanted to find out how the gender preference of best friends, as defined by the frequency of the calling, changed over the course of a lifetime and differed between men and women. They found that men tend to choose a woman the same age as themselves - which the researchers presumed to be their girlfriend or wife - as a best friend much later in life than women do, and for a much shorter time. This occurs when they are in their early-30s, possibly during courtship, and stops after seven years or so. Women, however, choose a man of a similar age to be their best friend from the age of 20. He remains for about 15 years, after which time he's replaced by a daughter. The pendulum between the two sexes is swinging back towards women, says Prof Dunbar The researchers say that a woman's social world is intensely focussed a on one individual and will shift as a result of reproductive interests from being the mate to children and grandchildren. According to Prof Dunbar, the data suggests that "at root the important relationships are those between women and not those between men". "Men's relationships are too casual. They often function at a high level in a political sense, of course; but at the end of the day, the structure of society is driven by women, which is exactly what we see in primates," he explains. Many anthropologists argue that most human societies are patriarchal on the basis that in most communities men stay where they are born whereas the wives move. But Professor Dunbar and his colleagues are arguing that this only occurs in agriculturally based societies. "If you look at hunter-gatherers and you look at modern humans in modern post-industrial societies, we are much more matriarchal. It's almost as if the pendulum between the two sexes, power-wise, is swinging (back) as we move away from agriculture toward a knowledge-based economy," he says.
