By Neuroskeptic Back in April a paper came out in Nature Reviews Neuroscience that shocked many: Katherine Button et al’s Power failure: why small sample size undermines the reliability of neuroscience It didn’t shock me, though, skeptic that I am: I had long suspected that much of neuroscience (and science in general) is underpowered – that is, that our sample sizes are too small to give us an acceptable chance of detecting the signals that we claim to be able to isolate out of the noise. In fact, I was so unsurprised by Button et al that I didn’t even read it, let alone write about it, even though the authors list included such neuro-blog favorites as John Ionaddis, Marcus Munafo and Brian Nosek (I try to avoid obvious favouritism, you see). However this week I took a belated look at the paper, and I noticed something interesting. Button et al took 49 meta-analyses and calculated the median observed statistical power of the studies in each analysis. The headline finding was that average power is small. I was curious to know why it was small. So I correlated the study characteristics (sample size and observed effect size) with the median power of the studies. I found that median power in a given meta-analysis was not correlated with the median sample size of those studies (d on the left, RR on the right):

Daniel Cressey Killing research animals is one of the most unpleasant tasks in science, and it is imperative to do it as humanely as possible. But researchers who study animal welfare and euthanasia are growing increasingly concerned that widely used techniques are not the least painful and least stressful available. This week, experts from across the world will gather in Newcastle upon Tyne, UK, to debate the evidence and try to reach a consensus. “There are lots of assumptions made about the humaneness of various techniques for euthanizing animals,” says Penny Hawkins, deputy head of the research animals department at the Royal Society for the Prevention of Cruelty to Animals, a charity based in Southwater, UK. “Sometimes an animal might not appear to be suffering, but might be conscious and suffering.” Much of the debate centres on rodents, which make up the vast majority of research animals. Current techniques for killing them include inhalation methods — such as chambers that fill with carbon dioxide or anaesthetic gases — and injecting barbiturates. Physical methods include cervical dislocation (breaking of the neck), or decapitation with specialist rodent guillotines (see ‘Methods used to kill lab rats’). Experts hotly debate which method is preferable. The most-discussed question at the meeting is likely to be about the use of CO2. © 2013 Nature Publishing Group

John Hawks Humans are known for sporting big brains. On average, the size of primates' brains is nearly double what is expected for mammals of the same body size. Across nearly seven million years, the human brain has tripled in size, with most of this growth occurring in the past two million years. Determining brain changes over time is tricky. We have no ancient brains to weigh on a scale. We can, however, measure the inside of ancient skulls, and a few rare fossils have preserved natural casts of the interior of skulls. Both approaches to looking at early skulls give us evidence about the volumes of ancient brains and some details about the relative sizes of major cerebral areas. For the first two thirds of our history, the size of our ancestors' brains was within the range of those of other apes living today. The species of the famous Lucy fossil, Australopithecus afarensis, had skulls with internal volumes of between 400 and 550 milliliters, whereas chimpanzee skulls hold around 400 ml and gorillas between 500 and 700 ml. During this time, Australopithecine brains started to show subtle changes in structure and shape as compared with apes. For instance, the neocortex had begun to expand, reorganizing its functions away from visual processing toward other regions of the brain. The final third of our evolution saw nearly all the action in brain size. Homo habilis, the first of our genus Homo who appeared 1.9 million years ago, saw a modest hop in brain size, including an expansion of a language-connected part of the frontal lobe called Broca's area. The first fossil skulls of Homo erectus, 1.8 million years ago, had brains averaging a bit larger than 600 ml. © 2013 Scientific American
By DAVID CRARY, AP National Writer NEW YORK (AP) — There's extensive evidence that pigs are as smart and sociable as dogs. Yet one species is afforded affection and respect; the other faces mass slaughter en route to becoming bacon, ham and pork chops. Seeking to capitalize on that discrepancy, animal-welfare advocates are launching a campaign called The Someone Project that aims to highlight research depicting pigs, chickens, cows and other farm animals as more intelligent and emotionally complex than commonly believed. The hope is that more people might view these animals with the same empathy that they view dogs, cats, elephants, great apes and dolphins. "When you ask people why they eat chickens but not cats, the only thing they can come up with is that they sense cats and dogs are more cognitively sophisticated that then species we eat — and we know this isn't true," said Bruce Friedrich of Farm Sanctuary, the animal-protection and vegan-advocacy organization that is coordinating the new project. "What it boils down to is people don't know farm animals the way they know dogs or cats," Friedrich said. "We're a nation of animal lovers, and yet the animals we encounter most frequently are the animals we pay people to kill so we can eat them." The lead scientist for the project is Lori Marino, a lecturer in psychology at Emory University who has conducted extensive research on the intelligence of whales, dolphins and primates. She plans to review existing scientific literature on farm animals' intelligence, identify areas warranting new research, and prepare reports on her findings that would be circulated worldwide via social media, videos and her personal attendance at scientific conferences. © 2013 Hearst Communications Inc.
Josh Howgego Thresher sharks can use their lengthy tail fins to swat sardines from shoals, researchers have found by taking underwater footage. Such tactical use of the tail fin during hunting — which was previously observed only in mammals such as dolphins and killer whales1 — might indicate that sharks are more intelligent than scientists thought. Pelagic thresher sharks (Alopias pelagicus) are nocturnal and notoriously shy. Researchers have long suspected that the shark uses its tail — which makes up half of its body length — to stun its prey, but the behaviour has not been documented before under natural conditions2. Simon Oliver, lead investigator of the Thresher Shark Research and Conservation Project, and his colleagues studied the sharks off the coast of Cebu, an island in the Philippines. Oliver, who is based at the University of Liverpool, UK, has been watching the animals during the day since 2005, but he hadn’t seen the sharks hunting until some divers saw it happening and phoned him. “Immediately I dropped everything and went to investigate,” he says. The sharks hunt by first lunging into a school of fish, priming their tails as they move in. They then swipe the tail in a trebuchet-like motion through an arc of 180o in just one-third of a second — fast enough to both physically hit the fish and to create a stunning shock wave (see image below). Each strike can take out up to seven sardines, so Oliver thinks it is probably the most energy-efficient way for the animals to hunt. The team published the results today in PLOS ONE3. © 2013 Nature Publishing Group
By MICHAEL WINERIP PETA, considered by many to be the highest-profile animal rights group in the country, kills an average of about 2,000 dogs and cats each year at its animal shelter here. And the shelter does few adoptions — 19 cats and dogs in 2012 and 24 in 2011, according to state records. At a time when the major animal protection groups have moved to a “no kill” shelter model, People for the Ethical Treatment of Animals remains a holdout, confounding some and incensing others who know the organization as a very vocal advocacy group that does not believe animals should be killed for food, fur coats or leather goods. This is an organization that on Thanksgiving urges Americans not to eat turkey. “Honestly, I don’t understand it,” says Joan E. Schaffner, an animal rights lawyer and an associate professor at the George Washington University Law School, which hosts an annual no-kill conference. “PETA does lots of good for animals, but I could never support them on this.” As recently as a decade ago, it was common practice at shelters to euthanize large numbers of dogs and cats that had not been adopted. But the no-kill movement has grown very quickly, leaving PETA behind. In New York City last year, 8,252 dogs and cats were euthanized, compared with 31,701 in 2003. “Through spay, neuter, transfer and adoption programs, we think New York City can close the gap toward becoming a ‘no-kill community’ by 2015,” said Matthew Bershadker, the president and chief executive of the American Society for the Prevention of Cruelty to Animals, one of 150 rescue groups and shelters that make up the Mayor’s Alliance for N.Y.C.’s Animals. © 2013 The New York Times Company

Gregory Gage is being honored as a Champion of Change for his dedication to increasing public engagement in science and science literacy. Science has a rich history of everyday citizens assisting in great discoveries, and I am honored that our work to encourage amateur neuroscience has been selected by The White House for the Citizen Science Champion of Change award. We know a lot about how our amazing brain works, but there is much, much more that remains to be discovered. In fact, we have no cures and only insufficient treatments for neurological disorder, even though about 1 out of every 5 people will be diagnosed with a brain disease. Change is indeed needed in our nation’s approach to science education to bring more focus on neuroscience. I am a “DIY” neuroscientist. I co-founded a low-fi company called Backyard Brains with my grad-school labmate, Tim Marzullo. While working on our Ph.D., we would often go out to local public schools to talk about the importance of studying neuroscience. We developed our lesson plans using models and analogies about how the brain works, but what we really wanted to teach the students was “electrophysiology”... as this is truly is how the brain works. The brain is an electrical organ, and the cells (neurons) communicate with “spikes”: a brief pulse of electricity. In my research at the university, I would record these spikes to learn what the neurons were telling us about how the brain worked. Traditionally, to do experiments with electrophysiology, one needs to be in a Ph.D. program and use expensive equipment (our electrophysiology rig cost $40,000). To make this accessible for our outreach goals, Tim and I set out on a self-imposed engineering challenge: to reduce this equipment down to the basic components, and record a spike for <$100. Less than a year later, we got our first prototype to work and were able to bring spikes into the classrooms! After getting requests from colleagues and teachers, we launched Backyard Brains. We are now a growing education company with neuroscience gear in over 45 countries on all 7 continents!

Posted by Alison Abbott Two months after animal-rights activists broke into an animal facility at the University of Milan and removed hundreds of animals, photographs of many of the mice have appeared on the Facebook page of one of the protestors’ supporters who uses the pen name Jooleea Carleenee. The raid took place on 20 April. Researchers at the university said that they lost years of their work along with the animals, most of which were genetically modified mice serving as models for disease. They said that they did not expect mutants that were particularly delicate, or immunosuppressed ‘nude’ mice, to survive outside controlled laboratory conditions. Carleenee says that she posted the pictures to show that the animals were still alive. But the images of the overcrowded and uncontrolled conditions in which the mice appear to have been kept in her home have fuelled a new row, with scientists posting angry comments, complaining of cruelty. Daria Giovannoni, president of the pro-science lobby group Pro-Test Italia, says: “If these photos show the actual conditions of the stolen mice, we’re seriously concerned about their well-being and health: we don’t think that these animals are faring better now than when they were in the laboratory.” The raid on 20 April spurred the nascent Pro-Test Italia — modelled on UK and US Pro-Test organizations — to action. It arranged a series of demonstrations by scientists in defence of their work on animals. © 2013 Nature Publishing Group

Posted by Gary Marcus Aristotle thought that the function of the brain was to cool the blood. That seems ludicrous now; through neuroscience, we know more about the brain and how it works than ever before. But, over the past several years, enthusiasm has often outstripped the limits of what current science can really tell us, and the field has given rise to pop neuroscience, which attempts to explain practically everything about human behavior and culture through the brain and its functions. A backlash against pop neuroscience is now in full swing. The latest, and most cutting, critique yet is “Brainwashed: The Seductive Appeal of Mindless Neuroscience,” by Sally Satel and Scott Lilienfeld. The book, which slams dozens of inconclusive studies that have been spun into overblown and downright dubious fields, like neurolaw and neuromarketing, is a resounding call for skepticism of the most grandiose claims being made in the name of neuroscience. The authors describe it as “an exposé of mindless neuroscience: the oversimplification, interpretive license, and premature application of brain science in the legal, commercial, clinical, and philosophical domains." The book does a terrific job of explaining where and how savvy readers should be skeptical. Unfortunately, the book is also prone to being misread. This is partly because it focusses largely on neuroscience’s current limitations rather than on its progress. Some, like David Brooks in the New York Times, are using books like “Brainwashed” as an excuse to toss out neuroscience altogether. In Brooks’s view, Satel and Lilienfeld haven’t just exposed some bad neuroscience; they’ve gutted the entire field, leading to the radical conclusion that “the brain is not the mind.” Brooks goes so far as to suggest that “it is probably impossible to look at a map of brain activity and predict or even understand the emotions, reactions, hopes and desires of the mind,” and that “there appears to be no dispersed pattern of activation that we can look at and say, ‘That person is experiencing hatred.’ ” The core of his claim is the idea that, if activity is distributed throughout the brain, it cannot be understood or interpreted. © 2013 Condé Nast.
By Felicity Muth Pigs are one of the top animals consumed across the world. According to the US Census Bureau, in 2010, around one hundred million metric tons of pork were consumed that year, with 10% of this being in the US (although it does seem that overall meat consumption is declining). With so many of us eating pork, you might think we’d know a bit more about these animals. A lot of people are surprised to hear about some of the cognitive abilities of the average pig. While it’s problematic to call an animal ‘intelligent’ or not, as this is a term is ill-defined and too often related to human cognition, pigs have shown us that they have a number of cognitive abilities tested across many different types of test. They have good learning and memory in many contexts (both short- and long-term), including episodic memory (memory for past events in their life), the ability to differentiate between familiar and unfamiliar pigs, and an inclination to explore novel objects. In addition to these behavioural feats, the pig brain is well-developed. For example, the volume of the prefrontal cortex is around 24% of the total neocortex and 10% of the total brain volume, comparable to primates including humans. I’m not sure why, despite this research, pigs have a reputation for being ‘stupid’. Similar to the ‘three-second memory’ myth with fish, I wonder if it’s perpetuated to make people not feel bad about eating these animals, or the conditions under which they are often reared. © 2013 Scientific American
by Satoshi Kanazawa in The Scientific Fundamentalist Drinking alcohol is evolutionarily novel, so the Hypothesis would predict that more intelligent people drink more alcohol than less intelligent people. The human consumption of alcohol probably originates from frugivory (consumption of fruits). Fermentation of sugars by yeast naturally present in overripe and decaying fruits produces ethanol, known to intoxicate birds and mammals. However, the amount of ethanol alcohol in such fruits ranges from trace to 5%, roughly comparable to light beer. (And you can't really get drunk on light beer.) It is nothing compared to the amount of alcohol present in regular beer (4-6%), wine (12-15%), and distilled spirits (20-95%). Human consumption of alcohol, however, was unintentional, accidental, and haphazard until about 10,000 years ago. The intentional fermentation of fruits and grain to yield ethanol arose only recently in human history. The production of beer, which relies on a large amount of grain, and that of wine, which similarly requires a large amount of grapes, could not have taken place before the advent of agriculture around 8,000 BC and the consequent agricultural surplus. Archeological evidence dates the production of beer and wine to Mesopotamia at about 6,000 BC. The origin of distilled spirits is far more recent, and is traced to Middle East or China at about 700 AD. The word alcohol - al kohl - is Arabic in origin, like many other words that begin with "al," like algebra, algorithm, alchemy, and Al Gore. Human experience with concentrations of ethanol higher than 5% that is attained by decaying fruits is therefore very recent. © Copyright 2002-2013 Sussex Directories, Inc.
by Marta Paterlini Tourists visiting the famous Spanish Steps in Rome on Saturday were treated to an unusual spectacle: Some 30 researchers suddenly showed up, unfolded banners and placards in different languages, and stood motionless on the steps for several minutes. Their flash mob was part of an unprecedented series of events across Italy to protest what organizers say is an antiscientific attitude in Italy and widespread "misinformation" about science in the media. Saturday's event, called Italy United for Correct Scientific Information, was organized by young researchers in response to an attack against an animal facility at the University of Milan in April, in which animal rights activists released mice and rabbits and ruined experiments. Some 300 researchers had already demonstrated on 1 June in Italy to defend animal experimentation; the new protests, which included flash mobs and conferences in 15 cities, were aimed more broadly. "We want to show that we do not live in an ivory tower," says organizer Dario Padovan, a biologist at the University of Trieste. "We are not afraid to defend our research and understand the need of communicating it correctly." Press coverage of April's attack showed again that in Italy, important scientific topics "are often addressed and reported by the media in a superficial, or even wrong, way" says Federico Baglioni, one of the organizers of Saturday's events. Previous examples were the conviction of Italian researchers for their failure to warn about the risk of a deadly earthquake in L'Aquila and the recent debate about the Stamina Foundation, which offers stem cell therapies that many scientists say aren't scientifically proven. In such debates, Italian media tend to focus on the emotional side of the story and fail to delve into the scientific facts, Baglioni says. © 2010 American Association for the Advancement of Science.

By Jason G. Goldman Within the wildlife conservation community, both in the field (“in situ“) as well as in captive settings (“ex situ“), there is a great deal of folk knowledge about the best methods for animal care as well as species protection and restoration. Increasingly, however, empirical knowledge from psychology and cognitive science can be brought to bear on husbandry, management, and conservation-related issues and can inform best practices. Here’s one small example. At the Los Angeles Zoo, I recently participated in a study with on the effects of environmental enrichment on meerkat behavior. Thoughtfully designed environmental enrichment programs, it is thought, allow captive animals to display a wider variety of naturalistic behaviors. A wealth of evidence suggests that when animals exhibit their natural behaviors, zoo visitors have a better and more educational experience, and animal welfare is increased. Unfortunately, one side effect of captivity is the possible emergence of non-naturalistic repetitive or stereotypic behaviors. Stereotypic behaviors vary according to the species, but might include swaying, coprophagy, regurgitation and reingestion, or pacing. When combined with stereotypic swimming patterns, pacing may actually be the most common form of stereotypy across species in modern zoos. While these behaviors may in fact be more stressful for zoo visitors than for the animals themselves, zoos still have a responsibility to minimize them as much as possible. Other stereotypies may feature or result in various forms of self-harm, which are of course more dangerous. Birds pluck their feathers, horses nip at their flanks, canids, felids, and bears over-groom themselves, turtles may bite their legs, and snakes may chew on their tails. © 2013 Scientific American

by Debora MacKenzie YOUR eye colour is a product of your DNA, but what about your IQ? The biggest-ever search for genes that affect intelligence, and the first to give reproducible results, has found 10 variations in DNA that seem to influence intelligence – but not by much. Studies of families show intelligence is 40 to 50 per cent inherited, and otherwise depends on environment. Since mass-analysis of DNA variations became possible, a number of studies have sought the genes involved in this inheritance, and some papers have claimed strong associations between particular genes and IQ. Yet results have varied widely and none have been replicated. "Many of the published findings of the last decade are wrong," says John Hewitt of the University of Colorado in Boulder, who was not involved in the new study. So if intelligence is inherited, where are the genes hiding? The research may have hit problems because each gene linked with IQ has only a tiny effect on overall intelligence. This means you need data on a large number of people to reliably distinguish such effects from measurement error. Most studies have involved between 100 and 2000 subjects. Now, some 200 researchers have assembled 54 sets of data on more than 126,000 people who have had their genomes analysed for 2.5 million common, small mutations called SNPs. Information was also available for how long they spent in education and the level they reached. © Copyright Reed Business Information Ltd.
People with higher IQs are slow to detect large background movements because their brains filter out non-essential information, say US researchers. Instead, they are good at detecting small moving objects. The findings come in a study of 53 people given a simple, visual test in Current Biology. The results could help scientists understand what makes a brain more efficient and more intelligent. In the study, individuals watched short video clips of black and white bars moving across a computer screen. Some clips were small and filled only the centre of the screen, while others filled the whole screen. The participants' sole task was to identify in which direction the bars were drifting - to the right or to the left. Participants also took a standardised intelligence test. The results showed that people with higher IQ scores were faster at noticing the movement of the bars when observing the smallest image - but they were slower at detecting movement in the larger images. Michael Melnick of the University of Rochester, who was part of the research team said the results were very clear. "From previous research, we expected that all participants would be worse at detecting the movement of large images, but high IQ individuals were much, much worse. The authors explain that in most scenarios, background movement is less important than small moving objects in the foreground, for example driving a car, walking down a hall or moving your eyes across the room.

Jeremy Laurance Iodine deficiency is widespread amongst pregnant women in the UK and may be harming the cognitive development of their children, scientists have found. The first large study of the problem in the UK has revealed that two-thirds of expectant mothers had a mild to moderate deficiency in the mineral, which was associated with significantly lower IQ and reading ability in their children at the ages of eight and nine. Iodine is essential for growth and development of the brain, and pregnant women need 50 per cent more. Researchers said women should ensure they are getting enough from their diet – milk, yogurt and fish are the best sources – and that any pregnancy supplement they take contains iodine. But they warned that kelp and seaweed supplements should be avoided as they contain variable levels of iodine and could lead to overdose. Severe iodine deficiency is known to cause brain damage and is the biggest cause of mental deficiency in the developing world. But mild to moderate iodine deficiency has been little studied – until now. Researchers from the Universities of Surrey and Bristol examined records of 1,000 mothers who were part of the Children of the 90s study which has followed the development of children born to 14,000 mothers in Avon since 1990-91. They found that 67 per cent of the mothers had levels of iodine below that recommended by the World Health Organisation. Their children were divided into groups according to how well they performed on IQ and reading tests at eight and nine. The results showed those whose mothers had low iodine levels were 60 per cent more likely to be in the bottom group. © independent.co.uk
By Maia Szalavitz There are many roads to greatness, but logging 10,000 hours of practice to help you perfect a skill may not be sufficient. Based on research suggesting that practice is the essence of genius, best-selling author Malcolm Gladwell popularized the idea that 10,000 hours of appropriately guided practice was “the magic number of greatness,” regardless of a person’s natural aptitude. With enough practice, he claimed in his book Outliers, anyone could achieve a level of proficiency that would rival that of a professional. It was just a matter of putting in the time. But in the years since Gladwell first pushed the “10,000-hours rule,” researchers have engaged in a spirited debate over what that rule entails. It’s clear that not just any practice, but only dedicated and intensive honing of skills that counts. And is there magic in that 10,000th hour? In an attempt to answer some of these questions, and to delve further into how practice leads to mastery, Zach Hambrick, associate professor of psychology at Michigan State University, and his colleagues decided to study musicians and chess players. It helps that both skills are amenable to such analysis because players can be ranked almost objectively. So in their research, which was published in the journal Intelligence, they reanalyzed data from 14 studies of top chess players and musicians. They found that for musicians, only 30% of the variance in their rankings as performers could be accounted for by how much time they spent practicing. For chess players, practice only accounted for 34% of what determined the rank of a master player. © 2013 Time Inc. All rights reserved
Ed Yong The US adolescents who signed up for the Study of Mathematically Precocious Youth (SMPY) in the 1970s were the smartest of the smart, with mathematical and verbal-reasoning skills within the top 1% of the population. Now, researchers at BGI (formerly the Beijing Genomics Institute) in Shenzhen, China, the largest gene-sequencing facility in the world, are searching for the quirks of DNA that may contribute to such gifts. Plunging into an area that is littered with failures and riven with controversy, the researchers are scouring the genomes of 1,600 of these high-fliers in an ambitious project to find the first common genetic variants associated with human intelligence. The project, which was launched in August 2012 and is slated to begin data analysis in the next few months, has spawned wild accusations of eugenics plots, as well as more measured objections by social scientists who view such research as a distraction from pressing societal issues. Some geneticists, however, take issue with the study for a different reason. They say that it is highly unlikely to find anything of interest — because the sample size is too small and intelligence is too complex. Earlier large studies with the same goal have failed. But scientists from BGI’s Cognitive Genomics group hope that their super-smart sample will give them an edge, because it should be enriched with bits of DNA that confer effects on intelligence. “An exceptional person gets you an order of magnitude more statistical power than if you took random people from the population — I’d say we have a fighting chance,” says Stephen Hsu, a theoretical physicist from Michigan State University in East Lansing, who acts as a scientific adviser to BGI and is one of the project’s leaders. © 2013 Nature Publishing Group,
Nathan J. Winograd People for the Ethical Treatment of Animals (PETA) is an organization that publicly claims to represent the best interest of animals -- indeed their "ethical treatment." Yet approximately 2,000 animals pass through PETA's front door every year and very few make it out alive. The vast majority -- 96 percent in 2011 -- exit the facility out the back door after they have been killed, when Pet Cremation Services of Tidewater stops by on their regular visits to pick up their remains. Between these visits, the bodies are stored in the giant walk-in freezer PETA installed for this very purpose. It is a freezer that cost $9,370 and, like the company which incinerates the bodies of PETA's victims, was paid for with the donations of animal lovers who could never have imagined that the money they donated to help animals would be used to end their lives instead. In fact, in the last 11 years, PETA has killed 29,426 dogs, cats, rabbits, and other domestic animals. Most animal lovers find this hard to believe. But seeing is believing. And if it is true that a picture speaks a thousand words, the following images speak volumes about who and what PETA really stands for. The PETA headquarters is on the aptly named Front Street. While claiming to be an animal rights organization, PETA does not believe animals have a right to live. Instead, it believes that people have a right to kill them, as long as the killing is done "humanely," which PETA interprets to mean poisoning them with an overdose of barbiturates, even if the animals are not suffering. In 2012, 733 dogs entered this building. They killed 602 of them. Only 12 were adopted. Also in 2012, they impounded 1,110 cats. 1,045 were put to death. Seven of them were adopted. They also took in 34 other companion animals, such as rabbits, of which 28 were put to death. Only four were adopted. © 2013 TheHuffingtonPost.com, Inc

Alison Abbott Activists occupied an animal facility at the University of Milan, Italy, at the weekend, releasing mice and rabbits and mixing up cage labels to confuse experimental protocols. Researchers at the university say that it will take years to recover their work. Many of the animals at the facility are genetic models for psychiatric disorders such as autism and schizophrenia. No arrests have been made following the 12-hour drama, which took place on Saturday, although the university says that it will press charges against the protesters. The activists took some of the animals and were told during negotiations that they would be permitted to come back later and take more. The attack was staged by the animal-rights group that calls itself Fermare Green Hill (or Stop Green Hill), in reference to the Green Hill dog-breeding facility near Brescia, Italy, which it targets for closure. Five activists entered laboratories in the university’s pharmacology department on Saturday morning. The lack of signs of a break-in suggests that the activists may have used an illegally acquired electronic card, says pharmacologist Francesca Guidobono-Cavalchini, who works there. They prised open the reinforced doors of the facility on the fourth floor, and two of them chained themselves by the neck to the main double doors such that any attempt to open the doors could have endangered their lives. © 2013 Nature Publishing Group
