Search for Survivors Races On as 91 Feared Dead in Tornado-Hit Oklahoma
Pre-dawn emergency workers searched feverishly for survivors in the rubble of homes, primary schools and an hospital in an Oklahoma City suburb ravaged by a massive Monday afternoon tornado feared to have killed up to 91 people and injured well over 200 residents.

Without Glia, the Brain Would Starve
The brain is voracious: compared with other organs, it consumes 10 times more oxygen and nutrients, receiving them by way of dense networks of blood vessels. Scientists know how these networks initially grow, but a surprising new study suggests that they are stabilized in early life by stem cells in the brain called radial glia. The finding could have significant implications for our understanding of Alzheimer's disease, a condition characterized in part by brainwide vascular problems.

You Are Less Beautiful Than You Think
In April 15, 2013 Dove launched a 3-minute video entitled “Dove Real Beauty Sketches.” The video achieved instant popularity and has been watched millions of times -- a successful viral campaign which has been widely talked about . In the video, a small group of women are asked to describe their faces to a person whom they cannot see. The person is a forensic artist who is there to draw pictures of the women based on their verbal descriptions. A curtain separates the artist and the women, and they never see each other. Before all this, each woman is asked to socialize with a stranger, who later separately descr...

No-Kill, High-Resolution 3-D Movies of Cells Now Possible [Video + Infographic]
Lillian Fritz-Laylin is observing a strain of leukemia cell that zips along at about 10 to 20 microns per minute. She’s looking for the motive secret of how these speed demons of the cellular world get around, and she’s doing it by making a high-resolution 3-D micro movie.

Good Gut Bacteria May Keep Bad At Bay
Most E. coli bacteria are harmless. It’s the rare, pathogenic strains that can cause bloody diarrhea, kidney disease, or death. But many of us may already be carrying the antidote--a healthy colony of gut bacteria. Because a study finds that when bad E. coli get in, beneficial microbes appear to keep them at bay. In mice, at least. [More] (Source: Scientific American - Official RSS Feed)

Genetic variation in KCNA5: impact on the atrial-specific potassium current IKur in patients with lone atrial fibrillation
Conclusion This study is the first to present gain-of-function mutations in KCNA5 in patients with early-onset lone AF. We identified three gain-of-function and three loss-of-function mutations. We report a high prevalence of variants in KCNA5 in these patients. This supports the hypothesis that both increased and decreased potassium currents enhance AF susceptibility.

Angelina Jolie and the One Percent
After learning that she had inherited a mutation on one of the so-called breast cancer genes, actress Angelina Jolie decided to have a double mastectomy to reduce her risk of developing breast cancer. She also plans to have her ovaries removed to reduce her risk of ovarian cancer. It may sound like a drastic measure, but mutations on the breast cancer genes ( BRCA1 and BRCA2 ) increase the overall risk of developing several cancers, including prostate, pancreatic, testicular, ovarian, and breast. On average, a woman with a BRCA1 mutation (the one Jolie has) has a 65 percent risk of developing breast cancer and a 39 percent...

Interventions to Prevent Post-Traumatic Stress Disorder: A Systematic Review
Conclusions: Evidence is very limited regarding best practices to treat trauma-exposed individuals. Brief cognitive behavioral therapy may reduce PTSD symptom severity in people with acute stress disorder; collaborative care may help decrease symptom severity post-injury.

Development of the Knee Numeric‐Entity Evaluation Score (KNEES – ACL): A condition‐specific questionnaire
Patient‐related outcome measures (PROMs) are commonly used to gauge treatment effects in patients with anterior cruciate ligament (ACL) deficiency. Valid measures of specific conditions depend on relevant item content. While item content can be derived either from clinicians (face validity) or from patients, item relevance and comprehensiveness can only be confirmed by the patient (content validity). Focus group and single interviews were conducted with patients' pre‐ and post‐ACL reconstruction in order to construct a condition‐specific PROM for the target patients. One hundred fifty‐seven items from a previousl...

Pesticide Makers Seek Answers as Bee Losses Sting Agriculture
By Carey Gillam(Reuters) - Monsanto Co is hosting a "Bee Summit." Bayer AG is breaking ground on a "Bee Care Center." And Sygenta AG is funding grants for research into the accelerating demise of honeybees in the United States, where the insects pollinate fruits and vegetables that make up roughly a quarter of the American diet.The agrichemical companies are taking these initiatives at a time when their best-selling pesticides are under fire from environmental and food activists who say the chemicals are killing off millions of bees.

The Overwhelming Odds Of Climate Change
If you listen to global warming deniers, or even much of the public , it seems like there is some stack of scientific studies somewhere that refute anthropogenic--human-caused--climate change. If someone would just let them reach into that pile and pull out a paper, we'd all see that climate change is "a hoax," or so it seems in our fractured discourse.

DSM-5: Caught between Mental Illness Stigma and Anti-Psychiatry Prejudice
Like many psychiatrists, I have been amazed by the debates surrounding the DSM-5 , the first major revision of the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders in nearly twenty years, which was just released. Never before has a thick medical text of diagnostic nomenclature been the subject of so much attention.Although I was heartened to see more and more people discussing the real-world issues and challenges--for patients, families, clinicians and caregivers-within mental health care, for which the book offers an up-to-the-minute diagnostic GPS, I was also alarmed at the harsh c...

China's One-Child Policy Affects Personality
In 1979 China instituted the one-child policy, which limited every family to just one offspring in a controversial attempt to reduce the country's burgeoning population. The strictly enforced law had the desired effects: in 2011 researchers estimated that the policy prevented 400 million births. In a new study in Science , researchers find that it has also caused China's so-called little emperors to be more pessimistic, neurotic and selfish than their peers who have siblings.
