| Gossip, ostracism may have hidden group benefits Posted: 27 Jan 2014 04:38 PM PST Conventional wisdom holds that gossip and social exclusion are always malicious, undermining trust and morale in groups. But sharing this kind of "reputational information" could have benefits for society, according to a new study. |
| New, giant virus kills anthrax agent Posted: 27 Jan 2014 04:38 PM PST From a zebra carcass on the plains of Namibia in Southern Africa, an international team of researchers has discovered a new, unusually large virus (or bacteriophage) that infects the bacterium that causes anthrax. The novel bacteriophage could eventually open up new ways to detect, treat or decontaminate the anthrax bacillus and its relatives that cause food poisoning. |
| Natural plant compound prevents Alzheimer's disease in mice Posted: 27 Jan 2014 04:37 PM PST A chemical that's found in fruits and vegetables from strawberries to cucumbers appears to stop memory loss that accompanies Alzheimer's disease in mice, scientists have discovered. In experiments on mice that normally develop Alzheimer's symptoms less than a year after birth, a daily dose of the compound -- a flavonol called fisetin -- prevented the progressive memory and learning impairments. The drug, however, did not alter the formation of amyloid plaques in the brain, accumulations of proteins which are commonly blamed for Alzheimer's disease. |
| Posted: 27 Jan 2014 04:37 PM PST Scientists have discovered that two of the world's most devastating plagues -- the plague of Justinian and the Black Death, each responsible for killing as many as half the people in Europe -- were caused by distinct strains of the same pathogen, one that faded out on its own, the other leading to worldwide spread and re-emergence in the late 1800s. These findings suggest a new strain of plague could emerge again in humans in the future. |
| Belief in immortality hard-wired? Study examines development of children's 'prelife' reasoning Posted: 27 Jan 2014 01:48 PM PST By examining children's ideas about "prelife," the time before conception, researchers found results which suggest that our bias toward immortality is a part of human intuition that naturally emerges early in life. And the part of us that is eternal, we believe, is not our skills or ability to reason, but rather our hopes, desires and emotions. |
| Critical protein discovered for healthy cell growth in mammals Posted: 27 Jan 2014 01:48 PM PST A protein that is required for the growth of tiny, but critical, hair-like structures called cilia on cell surfaces has been discovered. The research has important implications for human health because lack of cilia can lead to serious diseases such as polycystic kidney disease, blindness and neurological disorders. |
| Yoga can lower fatigue, inflammation in breast cancer survivors Posted: 27 Jan 2014 01:44 PM PST Practicing yoga for as little as three months can reduce fatigue and lower inflammation in breast cancer survivors, according to new research. The more the women in the study practiced yoga, the better their results. |
| Traumatic spinal cord injuries on the rise in U.S. Posted: 27 Jan 2014 11:19 AM PST The number of serious traumatic spinal cord injuries is on the rise in the United States, and the leading cause no longer appears to be motor vehicle crashes, but falls, new research suggests. |
| Study casts doubt on theory that retired NFL players suffer CTE Posted: 27 Jan 2014 11:19 AM PST The media have widely reported that a debilitating neurological condition called chronic traumatic encephalopathy (CTE) is a well-established disease in retired athletes who played football and other contact sports. But a study has found little evidence that CTE actually exists. |
| Promising class of antibiotics discovered for treatment of drug-resistant tuberculosis Posted: 27 Jan 2014 11:19 AM PST Scientists have discovered a promising new class of antibiotics that could aid efforts to overcome drug-resistance in tuberculosis (TB), a global killer. The drugs increased survival of mice infected with TB and were effective against drug-resistant strains of TB. |
| Low vitamin D levels during pregnancy may increase risk of severe preeclampsia Posted: 27 Jan 2014 11:19 AM PST Women who are deficient in vitamin D in the first 26 weeks of their pregnancy may be at risk of developing severe preeclampsia, a potentially life-threatening disorder diagnosed by an increase in blood pressure and protein in the urine, according to research. |
| Choosing Wisely: Politics, economics of labeling low-value services Posted: 27 Jan 2014 11:18 AM PST The Choosing Wisely campaign lists of services developed by physicians' specialty societies, is a good start to spark discussion between physicians their patients about treatments and tests that may not be warranted. But researchers say the list could be improved to include more common services and higher cost services. |
| Scientists find genetic mechanism linking aging to specific diets Posted: 27 Jan 2014 11:18 AM PST In new research published, scientists identify a collection of genes that allow an organism to adapt to different diets and show that without them, even minor tweaks to diet can cause premature aging and death. |
| Study identifies high level of 'food insecurity' among college students Posted: 27 Jan 2014 11:18 AM PST One of the few studies of its type has found that a startling 59 percent of college students at one university were "food insecure" at some point during the previous year, with possible implications for academic success, physical and emotional health and other issues. |
| HIV medications dialogue differs by race, ethnicity Posted: 27 Jan 2014 11:18 AM PST Researchers found specific racial and ethnic differences in discussions of HIV medicine adherence in a newly published analysis of recorded office visits between 45 doctors and nurse practitioners and more than 400 patients. |

| Posted: 27 Jan 2014 11:17 AM PST A new study has found that healthy 12-year-olds who score well in addition and multiplication have higher-quality white matter tracts. This correlation does not appear to apply to subtraction and division. |
| Posted: 27 Jan 2014 11:17 AM PST 79 million Americans are thought to have "prediabetes," a condition that puts them at risk of developing type-2 diabetes. Now researchers have discovered that a simple blood test can reveal an individual's risk of developing type-2 diabetes before they develop prediabetes -- far earlier than previously believed. The findings could help doctors provide earlier diagnosis and treatment. |
| Researchers shed new light on double-lung transplants Posted: 27 Jan 2014 11:17 AM PST In the largest retrospective study to date using data from the United Network for Organ Sharing database for adult double-lung transplants, researchers have shown that there is no statistically significant difference between rejection and mortality rates among double-lung transplant recipients when their transplanted organs came from donors whose blood type was identical or compatible to their own. |
| Permanent changes in brain genes may not be so permanent after all Posted: 27 Jan 2014 11:15 AM PST In normal development, all cells turn off genes they don't need, often by attaching a chemical methyl group to the DNA, a process called methylation. Historically, scientists believed methyl groups could only stick to a particular DNA sequence: a cytosine followed by a guanine, called CpG. But in recent years, they have been found on other sequences, and so-called non-CpG methylation has been found in stem cells, and in neurons in the brain. |
| Facelift complications eased with help of new 3-D imaging technique Posted: 27 Jan 2014 11:15 AM PST New imaging technology allows scientists to analyze what happens within the smallest blood vessels during a cosmetic facelift. This finding could be used to prevent accidents during procedures and help clinicians reverse the ill effects if an injection doesn't go as planned. |
| Sticks and stones: Using curriculum to stop bullying Posted: 27 Jan 2014 11:15 AM PST Research finds the key to stop bullying is anti-bullying education in the school curriculum, and that teaching students empathy is as important "as teaching them science." |
| Severity of spatial neglect after stroke predicts long-term mobility recovery in community Posted: 27 Jan 2014 09:28 AM PST Stroke rehabilitation researchers report an association between acute, severe spatial neglect post stroke and long-term recovery of mobility. This new study indicates that severity of spatial neglect during the acute inpatient rehabilitation for right brain stroke may predict functional mobility in the community after discharge. |
| Researchers find changes to protein SirT1 Posted: 27 Jan 2014 09:28 AM PST Studies have suggested that the protein SirT1 may be protective in metabolic diseases and the effects of aging, and diminished SirT1 activity has been reported in various disease models including diabetes and metabolic syndrome. Maintaining a normal level of this protein may be effective in preventing obesity- and age-related diseases. |
| Preventing, treating common cold: Nothing to sneeze at Posted: 27 Jan 2014 09:27 AM PST How do you prevent and treat the common cold? Handwashing and zinc may be best for prevention whereas acetaminophen, ibuprofen and perhaps antihistamine-decongestant combinations are the recommended treatments, according to a review. |

| Position paper reveals enormous variation in worldwide usage of FRAX Posted: 27 Jan 2014 08:27 AM PST Doctors worldwide now use tools such as FRAX, a widely available online calculator, to help identify patients in need of osteoporosis treatment. A new position paper by the IOF Epidemiology and Quality of Life Working Group has assessed the uptake of FRAX worldwide. The study concludes that there were approximately 2.3 million FRAX calculations during a one-year period beginning in May 2012, with enormous variation in worldwide usage. |
| Punctured cell membranes lead to high blood pressure Posted: 27 Jan 2014 07:12 AM PST Researchers have identified how a mutated protein can lead to holes in a protein sitting in a cell's membrane. Such holes cause high blood pressure, and the discovery can now lead to new and better medication for high blood pressure. |
| Shadowy world of Britain's discount hitmen revealed in new study Posted: 27 Jan 2014 07:12 AM PST Contract killing is one of the least studied, but most intriguing areas of organized crime; and new research into British hitmen has found that in some cases victims were murdered for as little as £200. The first typological study of British hitmen has identified four main types of contract killer; the novice, the dilettante, the journeyman; and the master. |
| 300,000-year-old hearth found: Microscopic evidence shows repeated fire use in one spot over time Posted: 27 Jan 2014 07:12 AM PST When did humans really begin to control fire and use it for their daily needs? Scientists discovered in the Qesem Cave, an archaeological site near present-day Rosh Ha'ayin, the earliest evidence -- dating to around 300,000 years ago -- of unequivocal repeated fire building over a continuous period. These findings help answer the question and hint that those prehistoric humans already had a highly advanced social structure and intellectual capacity. |
| Sun-induced frowning: a possible cause of aggression? Posted: 27 Jan 2014 07:11 AM PST Research recently published examines how facial expression can trigger an emotional response. The authors set out to test this theory that mood can be governed by facial expression, to the extent that intensity of a person's smile bears a relationship to well-being, fulfillment and longevity. They conducted a study on involuntary sun-induced frowning and relationship to emotional state of the subject. |
| 'Element of surprise' explains why motorcycles are greater traffic hazard than cars Posted: 27 Jan 2014 07:10 AM PST "I didn't see it, because I wasn't expecting it there," might be the more accurate excuse for motorists who have just crashed into a bus or a motorcycle. The mere fact that such vehicles are less common than cars on our roads actually makes it harder for drivers to notice them, research shows. This so-called "low-prevalence effect" increases the likelihood of accidents. |
| Posted: 27 Jan 2014 07:09 AM PST More than 25 million people in the United States have asthma, a chronic lung disease that inflames and narrows the airways causing recurring periods of wheezing, chest tightness, shortness of breath and coughing. Although several types of drugs are available to treat asthma, long-acting beta agonists (LABAs) are among the most commonly used and work well for most people. However, for a small subgroup of people with asthma, LABAs can cause severe, life-threatening side effects. |
| FDA Approval of Revolutionary Two-Drug Combo to Treat Advanced Melanoma Posted: 27 Jan 2014 07:09 AM PST Researchers have laid the groundwork for a revolutionary new combination therapy for the treatment of advanced melanoma – melanoma that cannot be removed surgically or has spread to other areas of the body.
