By Nicholas Bakalar Treating pregnant women for depression may benefit not just themselves but their babies as well. A study, in the May issue of Obstetrics & Gynecology, included 7,267 pregnant women, of whom 831 had symptoms of depression. After controlling for maternal age, race, income, body mass index and other health and behavioral characteristics, the researchers found that depressive symptoms were associated with a 27 percent increased relative risk of preterm birth (less than 37 weeks of gestation), an 82 percent increased risk of very preterm birth (less than 32 weeks of gestation), and a 28 percent increased risk of having a baby small for gestational age. They also found that among those who were treated with antidepressants for depression — about a fifth of those with the diagnosis — there was no association with increased risk for any of these problems. But they acknowledge that this group was quite small, which limits the power to draw conclusions. Still, the lead author, Dr. Kartik K. Venkatesh, a clinical fellow in obstetrics and gynecology at Harvard, said that it was important to screen mothers for depression, not only for their health but for that of their babies. “By screening early in pregnancy, you could identify those at higher risk and counsel them about the importance of treatment,” he said. “Treating these women for depression may have real benefits.” © 2016 The New York Times Company
Anna Nowogrodzki Prions, the misfolded proteins that are known for causing degenerative illnesses in animals and humans, may have been spotted for the first time in plants. Researchers led by Susan Lindquist, a biologist at the Whitehead Institute for Biomedical Research in Cambridge, Massachusetts, report that they have found a section of protein in thale cress (Arabidopsis) that behaves like a prion when it is inserted into yeast. In plants, the protein is called Luminidependens (LD), and it is normally involved in responding to daylight and controlling flowering time. When a part of the LD gene is inserted into yeast, it produces a protein that does not fold up normally, and which spreads this misfolded state to proteins around it in a domino effect that causes aggregates or clumps. Later generations of yeast cells inherit the effect: their versions of the protein also misfold. This does not mean that plants definitely have prion-like proteins, adds Lindquist — but she thinks that it is likely. “I’d be surprised if they weren’t there,” she says. To prove it, researchers would need to grind up a plant and see whether they could find a protein such as LD in several different folded states, as well as show that any potential prion caused a misfolding cascade when added to a test-tube of protein. Lindquist adds that because she's not a plant scientist — her focus is on using yeast to investigate prions — she hasn't tried these experiments. The study is reported on 25 April in the Proceedings of the National Academy of Sciences1. © 2016 Nature Publishing Group
By Jordana Cepelewicz Everyone is familiar with the complaints of a hungry stomach. For years, scientists attributed the gnawing increase in appetite before a meal to ghrelin, a hormone which is secreted in the gut and circulates in the blood, playing a role in food intake and storage. Researchers have found that levels of ghrelin, dubbed the “hunger hormone,” peak before meals and recede after eating. Given its association with appetite, ghrelin is a tempting drug target for potential obesity treatments—but findings thus far have not lived up to expectations. Experiments that knock out the genes coding for ghrelin and its single receptor, GHSR (growth hormone secretagogue receptor), have been inconclusive: Remove the hormone or receptor, and rodents used in the experiments do not necessarily lose their drive to eat. Now a team of researchers at the French Institute of Health and Medical Research (INSERM) in Paris believe that scientists have had it wrong all along. In a study published this week in Science Signaling, they report that ghrelin does not enhance appetite in rats but rather increases weight gain and fat buildup. Unlike in earlier work, in the new study the researchers used a novel genetic method that kept the ghrelin receptor functional but modified it to have greater signaling in response to ghrelin—in other words, the receptor would enhance the hormone’s effects. The team then performed a series of experiments, first in isolated cells and then in rats. As expected, exposing ghrelin to modified receptors prompted a more potent response compared with the unaltered GHSR. © 2016 Scientific American
By Clare Wilson One day, you might be seeing in blue for 24 hours before you have an operation – to prevent organ damage. A study in mice suggests that exposure to blue light reduces a form of organ damage that is common during surgery. Reperfusion injury can happen when blood vessels are temporarily tied off during surgery, or when blocked arteries are surgically widened after a heart attack or stroke. Some damage is caused by a lack of oxygen, and further harm results when oxygen levels rebound, causing cells to become overactive, and triggering an attack by the immune system. But blue light seems to reduce this, in mice at least. Matthew Rosengart of the University of Pittsburgh, Pennsylvania, and his team have found that when mice are exposed to blue light for 24 hours before the blood supply to their liver or kidney is temporarily tied off, there is less reperfusion injury than if the mice are exposed to other types of light. “That’s pretty remarkable,” says Jack Pickard, a reperfusion researcher at University College London. Further tests showed that blue light seems to dampen down the sympathetic nervous system, which is involved in mammal stress responses. In turn, this reduced the activity of immune cells called neutrophils, which are involved in inflicting the damage of a reperfusion injury. © Copyright Reed Business Information Ltd.

Yuki Noguchi Hey! Wake up! Need another cup of coffee? Join the club. Apparently about a third of Americans are sleep-deprived. And their employers are probably paying for it, too, in the form of mistakes, productivity loss, accidents and increased health insurance costs. A recent Robert Wood Johnson Foundation report found a third of Americans get less sleep than the recommended seven hours. Another survey by Accountemps, an accounting services firm, put that number at nearly 75 percent in March. Bill Driscoll, Accountemps' regional president in the greater Boston area, says some sleepy accountants even admitted it caused them to make costly mistakes. "One person deleted a project that took 1,000 hours to put together," Driscoll says. "Another person missed a decimal point on an estimated payment and the client overpaid by $1 million. Oops. William David Brown, a sleep psychologist at the University of Texas Southwestern Medical School and author of Sleeping Your Way To The Top, says Americans are sacrificing more and more sleep every year. Fatigue is cumulative, he says, and missing the equivalent of one night's sleep is like having a blood alcohol concentration of about .1 — above the legal limit to drive. "About a third of your employees in any big company are coming to work with an equivalent impairment level of being intoxicated," Brown says. © 2016 npr
By Matthew A. Scult My heart pounds as I sprint to the finish line. Thousands of spectators cheer as a sense of elation washes over me. I savor the feeling. But then, the image slowly fades away and my true surroundings come into focus. I am lying in a dark room with my head held firmly in place, inside an MRI scanner. While this might typically be unpleasant, I am a willing research study participant and am eagerly anticipating what comes next. I hold my breath as I stare at the bar on the computer screen representing my brain activity. Then the bar jumps. My fantasy of winning a race had caused the “motivation center” of my brain to surge with activity. I am participating in a study about neurofeedback, a diverse and fascinating area of research that combines neuroscience and technology to monitor and modulate brain activity in real time. My colleagues, Katie Dickerson and Jeff MacInnes, in the Adcock Lab at Duke University, are studying whether people can train themselves to increase brain activity in a tiny region of the brain called the VTA. Notably, the VTA is thought to be involved in motivation—the desire to get something that you want. For example, if I told you that by buying a lottery ticket you would be guaranteed to win $1,000,000, you would probably be very motivated to buy the ticket and would have a spike in brain activity in this region of your brain. But while studies have shown that motivation for external rewards (like money) activate the VTA, until now, we didn’t know whether people could internally generate a motivational state that would activate this brain region. To see if people can self-activate the VTA, my colleagues are using neurofeedback, which falls under the broader umbrella of biofeedback. © 2016 Scientific American
By ANDREW POLLACK In a confrontation between the hopes of desperate patients and clinical trial data, advisers to the Food and Drug Administration voted on Monday not to recommend approval of what would become the first drug for Duchenne muscular dystrophy. The negative votes came despite impassioned pleas from patients, parents and doctors who insisted that the drug, called eteplirsen, was prolonging the ability of boys with the disease to walk well beyond when they would normally be in wheelchairs. The problem was that the drug’s manufacturer, Sarepta Therapeutics, was trying to win approval based on a study involving only 12 patients without an adequate placebo control. The advisory panel voted 7 to 3, with three abstentions, that the clinical data did not meet the F.D.A. requirements for well controlled studies necessary for approval. However, some of the panel members had trouble reconciling the often compelling patient testimony with the F.D.A. legal requirements. “I was just basically torn between my mind and my heart,” said Richard P. Hoffmann, a pharmacist who was the consumer representative on the committee and who abstained. Dr. Bruce I. Ovbiagele, chairman of neurology at the Medical University of South Carolina, voted against approval but said, “Based on all I heard, the drug definitely works, but the question was framed differently.” On another question of whether the drug could qualify for so-called accelerated approval, a lower hurdle, the panel voted 7 to 6 against the drug. The F.D.A., which does not have to follow the advice of its advisory panels, is scheduled to decide whether to approve eteplirsen by May 26. © 2016 The New York Times Company
by Laura Sanders Some researchers believe that when memories are called to mind, they enter a fragile, wobbly state during which they are vulnerable to being weakened or changed. One way to erode old memories is to learn something new just after recalling the older memory, scientists reported in 2003 (SN: 10/11/2003, p. 228). But that result itself is wobbly, scientists report April 25 in the Proceedings of the National Academy of Sciences. In an attempt to replicate the original finding, experimental psychologist Tom Hardwicke of University College London and colleagues didn’t see any memory alterations in people who learned a new sequence of finger taps shortly after recalling an old sequence. Nor did the researchers turn up signs of this memory interference in other tests. The new study focused specifically on new learning, but the findings cast suspicion on the legitimacy of other ways to interfere with people’s memories, Hardwicke says. Approaches such as brain stimulation or drugs might also be flawed, the researchers argue. © Society for Science & the Public 2000 - 2016

Richard A. Friedman DRUG companies are eager to tell you about their newest medicines. Turn on your TV or go online and there’s a new drug — with a hefty price tag — for whatever ails you, from antidepressants to painkillers to remedies for erectile dysfunction. The pharmaceutical industry spends lavishly to get your attention: In 2014, drug makers poured $4.5 billion into so-called direct-to-consumer advertising, a 30 percent increase over two years. Drug makers claim they are educating the public with their ads, providing information that will help you make better choices about your medical care. So in the spirit of education, let’s consider a recent online ad for Latuda, a new antipsychotic medication. A young woman rides a bike off into the sun as we are told that Latuda has been shown to be effective for many people with bipolar depression, followed by that staccato recitation of potential side effects that most viewers tune out. Here’s what a helpful prescription drug label could look like, with facts that are now out of reach. These are question marks because, although many clinical trial results are published, they are difficult to find and compare. Rules should mandate that all studies are accessible. Note the same high cost for a four-fold range of Latuda doses. Often the lowest dose is just as effective; some low-dose consumers realize they can save money by ordering the higher-dose units and splitting them into pieces. The ideal label would have statistics on how many people have serious side effects. Data are not included for these drugs because they may take years to emerge, if ever. Other drugs have well-known side effects. Fair enough. But the ad omits something that most consumers would like to know: There are many older and cheaper treatments that are just as effective. In fact, Latuda is one of 10 “second generation” antipsychotic medications, many available in generic forms, that essentially work the same way. Of course, the goal of drug companies is not to educate, but to sell products. We could ban the ads, as almost every other country does, and which I’d strongly support. But such a campaign in the United States would face fierce legislative and legal challenges. Instead, let’s help the drug companies make their ads truly educational. © 2016 The New York Times Company
It was December 2012 when the country learned about the massacre at Sandy Hook Elementary School, that left 20 children dead at the hands of 20-year-old shooter Adam Lanza. After the shock and the initial grief came questions about how it could have happened and why. Reports that Adam Lanza may have had some form of undiagnosed mental illness surfaced. The tragedy drove Liza Long to write a blog post on that same day, titled "I Am Adam Lanza's Mother." She wasn't Lanza's mom, but she was raising a child with a mental disorder. Her 13-year-old son had violent rages on a regular basis. He was in and out of juvenile detention. He had threatened to kill her. She detailed all this in her essay that took off online. Now, four years later, her son is speaking out too. This week on For The Record: a mother, a son and life on the edge of bipolar disorder. Eric Walton, Liza Long's son, is now a 16-year-old high school sophomore in Boise, Idaho. After a series of misdiagnoses, he's been diagnosed with bipolar disorder. But four years ago, he didn't know much about his condition. "I knew that there were times when I would have rages, didn't like them. I knew that I wanted them to stop," Walton says. Except he felt a loss of control in those moments. He describes the onset of these rages as a "blackout" of sorts. "I would start getting angry," he says. "Then it's like being trapped inside a box inside your own head. It was like a television on the wall that shows you what you're seeing. You can feel everything, but you no longer have the video game controller to control your own body." Walton's mom says when Eric would get into those states, "he would express a lot of suicidal thoughts, and hearing him just say, 'I want to die, I just want to end it.'" Then, two days before the Newtown shooting, Eric Walton had another episode. © 2016 npr
By THE EDITORIAL BOARD At the urging of Mexico, Guatemala and Colombia, world leaders met at the United Nations in a special session last week to discuss saner ways to fight the drug trade. They did not get very far toward a shift in approach. Nonetheless, there was a consensus that investing in health care, addiction treatment and alternatives to incarceration would do more to end the drug trade than relying primarily on prohibition and criminalization. “A war that has been fought for more than 40 years has not been won,” President Juan Manuel Santos of Colombia said in an interview. “When you do something for 40 years and it doesn’t work, you need to change it.” Mr. Santos and the presidents of Mexico and Guatemala argue that the war on drugs, which has been largely directed under terms set by the United States, has had devastating effects on their countries, which are hubs of the cocaine, marijuana and heroin trade. “When two elephants fight, the grass always suffers the most,” President Jimmy Morales of Guatemala said, referring to the drug cartels and American law enforcement agencies. Since 2014, the three governments and like-minded allies have sought to lay the groundwork for changes to the current approach, which is grounded in three international drug accords adopted between the early 1960s and 1988. Those treaties, which required that signatories outlaw the trade and possession of controlled substances — including marijuana — were conceived at a time when international leaders saw law enforcement as the most effective way to curb drug production and consumption. Unfortunately, several countries with considerable diplomatic clout, including China and Russia, maintain that criminalization should remain the cornerstone of the fight against drugs. © 2016 The New York Times Company

By Tulip Mazumdar Most people suffering with eating disorders in Japan are not receiving any medical or psychological support, according to doctors. The Japan Society for Eating Disorders claims the health system is failing hundreds of thousands of sufferers. It also says the pressure on girls, in particular, to be thin has "gone too far". The government says it's trying to set up more services and has tried to discover the extent of the problem. "I hated being chubby when I was a kid," says Motoko - who is using a different name to hide her identity. "The other kids bullied me so I always wanted to change." Motoko was 16 years old when her eating disorder started. She would severely limit how much she ate and then started exercising excessively. By the time she was 19, Motoko was dangerously underweight. She says her parents didn't know how to help her. "They were negative about my illness," she says. "When I tried to see my doctor, they told me not to. "My mother felt responsible, perhaps my father blamed her too." Fear of 'wasting food' Motoko's story is a familiar one. Stigma around eating disorders - for both sufferers and their families - prevent many people from coming forward. "They see actions such as binging on food and then vomiting (bulimia) as shameful," says clinical psychiatrist Dr Aya Nishizono-Maher, a member of The Japan Society for Eating Disorders. "They feel they have to hide it. Parents may think they are wasting food so that might stop them seeking help." After more than 10 years, Motoko finally started getting the help she needed and she now attends one of the few eating disorder community support groups which receives money from the government. © 2016 BBC.

By Leonard Sax, M.D., Ph.D Why is it that girls tend to be more anxious than boys? It may start with how they feel about how they look. Some research has shown that in adolescence, girls tend to become more dissatisfied with their bodies, whereas boys tend to become more satisfied with their bodies. Another factor has to do with differences in how girls and boys use social media. A girl is much more likely than a boy to post a photo of herself wearing a swimsuit, while the boy is more likely to post a photo where the emphasis is on something he has done rather than on how he looks. If you don’t like Jake’s selfie showing off his big trophy, he may not care. But if you don’t like Sonya’s photo of herself wearing her bikini, she’s more likely to take it personally. Imagine another girl sitting in her bedroom, alone. She’s scrolling through other girls’ Instagram and Snapchat feeds. She sees Sonya showing off her new bikini; Sonya looks awesome. She sees Madison at a party, having a blast. She sees Vanessa with her adorable new puppy. And she thinks: I’m just sitting here in my bedroom, not doing anything. My life sucks. Boys are at lower risk for the toxic effects of social media than girls are, for at least three reasons. First, boys are less likely to be heavily invested in what you think of their selfies. “Does this swimsuit make me look fat?” is a question asked by girls more often than by boys. Second, boys tend to overestimate how interesting their own life is. Third, the average boy is likely to spend more time playing video games than Photoshopping his selfie for Instagram. And in video games, unlike social media, everybody truly can be a winner, eventually. If you play Grand Theft Auto or Call of Duty long enough, you will, sooner or later, complete all the missions, if you just keep at it. © 2016 The New York Times Company
By Nicholas Bakalar Eating a high-fat diet may lead to daytime sleepiness, a new study concludes. Australian researchers studied 1,800 men who had filled out food-frequency questionnaires and reported on how sleepy they felt during the day. They were also electronically monitored for obstructive sleep apnea, which causes people to wake up many times during the night. After adjusting for factors that could influence sleep — smoking, alcohol intake, waist circumference, physical activity, medications, depression and others — they found that compared with those in the lowest one-quarter for fat intake, those in the highest one-quarter were 78 percent more likely to suffer daytime sleepiness and almost three times as likely to have sleep apnea. The connection of fat intake to apnea was apparent most clearly in people with a high body mass index, but the positive association of fat intake with daytime sleepiness persisted strongly in all subjects, regardless of B.M.I. Thestudy is in the journal Nutrients. “The possible mechanism could be meal timing, but we didn’t have that information,” said the lead author, Yingting Cao, a doctoral candidate at the University of Adelaide. “But we have reason to believe that circadian rhythm, hormones and diet all work together to create these effects. © 2016 The New York Times Company
Laura Sanders Away from home, people sleep with one ear open. In unfamiliar surroundings, part of the left hemisphere keeps watch while the rest of the brain is deeply asleep, scientists report April 21 in Current Biology. The results help explain why the first night in a hotel isn’t always restful. Some aquatic mammals and birds sleep with half a brain at a time, a trick called unihemispheric sleep. Scientists have believed that humans, however, did not show any such asymmetry in their slumber. Study coauthor Yuka Sasaki of Brown University in Providence, R.I., and colleagues looked for signs of asymmetry on the first night that young, healthy people came into their sleep lab. Usually, scientists toss the data from the inaugural night because the sleep is so disturbed, Sasaki says. But she and her team thought that some interesting sleep patterns might lurk within that fitful sleep. “It was a little bit of a crazy hunch,” she says, “but we did it anyway.” On the first night in a sleep lab, people with more “awake” left hemispheres took longer to fall asleep. This asymmetry was largely gone on the second night, and people fell asleep more quickly. During a deep sleep stage known as slow-wave sleep, a network of nerve cells in the left side of the brain showed less sleep-related activity than the corresponding network on the right side. Those results suggest that the left side of the brain is a lighter sleeper. “It looked like the left hemisphere and the right hemisphere did not show the same degree of sleep,” Sasaki says. This imbalance disappeared on the second night of sleep. © Society for Science & the Public 2000 - 2016
By Lisa L. Lewis On Tuesday, U.S. News and World Report released its annual public high-school rankings, with the School for the Talented and Gifted in Dallas earning the top spot for the fifth year in a row. The rankings are based on a wealth of data, including graduation rates and student performance on state proficiency tests and advanced exams, as well as other relevant factors—like the percentage of economically disadvantaged students the schools serve. But there’s one key metric that isn’t tracked despite having a proven impact on academic performance: school start times. First-period classes at the School for the Talented and Gifted start at 9:15 a.m. That’s unusually late compared to other schools but is in keeping with the best practices now recommended by public health experts. Teens require more sleep than adults and are hardwired to want to sleep in. Eight hours a night may be the goal for adults, but teens need between 8.5–9.5 hours, according to the American Academy of Pediatrics. Unfortunately, few teens meet that minimum: Studies show that two out of three high school students get less than eight hours of sleep, with high school seniors averaging less than seven hours. Sure, kids could go to bed earlier. But their bodies are set against them: Puberty makes it hard for them to fall asleep before 11 p.m. When combined with too-early start times, the result is sleep deprivation.
By SABRINA TAVERNISE WASHINGTON — Suicide in the United States has surged to the highest levels in nearly 30 years, a federal data analysis has found, with increases in every age group except older adults. The rise was particularly steep for women. It was also substantial among middle-aged Americans, sending a signal of deep anguish from a group whose suicide rates had been stable or falling since the 1950s. The suicide rate for middle-aged women, ages 45 to 64, jumped by 63 percent over the period of the study, while it rose by 43 percent for men in that age range, the sharpest increase for males of any age. The overall suicide rate rose by 24 percent from 1999 to 2014, according to the National Center for Health Statistics, which released the study on Friday. The increases were so widespread that they lifted the nation’s suicide rate to 13 per 100,000 people, the highest since 1986. The rate rose by 2 percent a year starting in 2006, double the annual rise in the earlier period of the study. In all, 42,773 people died from suicide in 2014, compared with 29,199 in 1999. From 1999 to 2014, suicide rates in the United States rose among most age groups. Men and women from 45 to 64 had a sharp increase. Rates fell among those age 75 and older. “It’s really stunning to see such a large increase in suicide rates affecting virtually every age group,” said Katherine Hempstead, senior adviser for health care at the Robert Wood Johnson Foundation, who has identified a link between suicides in middle age and rising rates of distress about jobs and personal finances. Researchers also found an alarming increase among girls 10 to 14, whose suicide rate, while still very low, had tripled. The number of girls who killed themselves rose to 150 in 2014 from 50 in 1999. “This one certainly jumped out,” said Sally Curtin, a statistician at the center and an author of the report. © 2016 The New York Times Company
Cassie Martin The grunts, moans and wobbles of gelada monkeys, a chatty species residing in Ethiopia’s northern highlands, observe a universal mathematical principle seen until now only in human language. The new research, published online April 18 in the Proceedings of the National Academy of Sciences, sheds light on the evolution of primate communication and complex human language, the researchers say. “Human language is like an onion,” says Simone Pika, head of the Humboldt Research Group at the Max Planck Institute for Ornithology in Seewiesen, Germany, who was not involved in the study. “When you peel back the layers, you find that it is based on these underlying mechanisms, many of which were already present in animal communication. This research neatly shows there is another ability already present.” As the number of individual calls in gelada vocal sequences increases, the duration of the calls tends to decrease — a relationship known as Menzerath’s law. One of those mechanisms is known as Menzerath’s law, a mathematical principle that states that the longer a construct, the shorter its components. In human language, for instance, longer sentences tend to comprise shorter words. The gelada study is the first to observe this law in the vocalizations of a nonhuman species. “There are aspects of communication and language that aren’t as unique as we think,” says study coauthor Morgan Gustison of the University of Michigan in Ann Arbor. © Society for Science & the Public 2000 - 2016
By Catherine Matacic Simi Etedgi leans forward as she tells her story for the camera: The year was 1963, and she was just 15 as she left Morocco for Israel, one person among hundreds of thousands leaving for the new state. But her forward lean isn’t a casual gesture. Etedgi, now 68, is one of about 10,000 signers of Israeli Sign Language (ISL), a language that emerged only 80 years ago. Her lean has a precise meaning, signaling that she wants to get in an aside before finishing her tale. Her eyes sparkle as she explains that the signs used in the Morocco of her childhood are very different from those she uses now in Israel. In fact, younger signers of ISL use a different gesture to signal an aside—and they have different ways to express many other meanings as well. A new study presented at the Evolution of Language meeting here last month shows that the new generation has come up with richer, more grammatically complex utterances that use ever more parts of the body for different purposes. Most intriguing for linguists: These changes seem to happen in a predictable order from one generation to the next. That same order has been seen in young sign languages around the world, showing in visible fashion how linguistic complexity unfolds. This leads some linguists to think that they may have found a new model for the evolution of language. “This is a big hypothesis,” says cognitive scientist Ann Senghas of Barnard College in New York City, who has spent her life studying Nicaraguan Sign Language (NSL). “It makes a lot of predictions and tries to pull a lot of facts together into a single framework.” Although it’s too early to know what the model will reveal, linguists say it already may have implications for understanding how quickly key elements of language, from complex words to grammar, have evolved. © 2016 American Association for the Advancement of Science.

Anna Nowogrodzki There’s a little too much wishful thinking about mindfulness, and it is skewing how researchers report their studies of the technique. Researchers at McGill University in Montreal, Canada, analysed 124 published trials of mindfulness as a mental-health treatment, and found that scientists reported positive findings 60% more often than is statistically likely. The team also examined another 21 trials that were registered with databases such as ClinicalTrials.gov; of these, 62% were unpublished 30 months after they finished. The findings — reported in PLoS ONE on 8 April1 — hint that negative results are going unpublished. Mindfulness is the practice of being aware of thoughts and feelings without judging them good or bad. Mental-health treatments that focus on this method include mindfulness-based stress reduction — an 8-week group-based programme that includes yoga and daily meditation — and mindfulness-based cognitive therapy. A bias toward publishing studies that find the technique to be effective withholds important information from mental-health clinicians and patients, says Christopher Ferguson, a psychologist at Stetson University in Florida, who was not involved in the study. “I think this is a very important finding,” he adds. “We’ll invest a lot of social and financial capital in these issues, and a lot of that can be misplaced unless we have good data.” © 2016 Nature Publishing Group
