Building a better rat maze could help us all cooperate Posted: 13 Oct 2016 10:01 AM PDT A fully-automated rat maze could help scientists better understand how individuals cooperate, and how this process may go awry in the brains of people with disorders ranging from autism to schizophrenia.

Researchers identify enzyme that removes molecular modifications from transfer RNA Posted: 13 Oct 2016 10:01 AM PDT The enzyme ALKBH1 can remove molecular modifications from transfer RNA, causing a measurable effect on protein translation in the cell, new research demonstrates. The study sheds new light on how cells control gene expression, and suggests the possibility that transfer RNA (tRNA) influences cellular processes beyond protein translation.

Tai chi can help relieve chronic neck pain, study shows Posted: 13 Oct 2016 10:01 AM PDT Tai Chi, a low-impact mind-body exercise, can be as effective as neck exercises in relieving persistent neck pain, according to results of randomized controlled trial.

Nutritional supplement could prevent thousands of early preterm births Posted: 13 Oct 2016 10:01 AM PDT Sophisticated analyses of two clinical trials suggest that thousands of early preterm births could be prevented if pregnant women took daily docosahexaenoic acid (DHA) supplements.

How a brain tumor's greed for cholesterol could be exploited for cancer therapy Posted: 13 Oct 2016 10:01 AM PDT A metabolic vulnerability in the aggressive and incurable brain cancer glioblastoma (GBM) has been discovered, report researchers who have shown how it can potentially be exploited for therapy.

Researchers say it's time to consider propranolol as an anti-cancer drug Posted: 13 Oct 2016 09:59 AM PDT Propranolol, a beta-blocker commonly prescribed to treat irregular heart rates and other conditions, has significant anti-cancer properties, say researchers in a new clinical study.

Saving lives by making pneumonia vaccine affordable Posted: 13 Oct 2016 08:59 AM PDT New groundbreaking research is on the threshold of aiding researchers in producing vaccines at prices that will propel their widespread use and help protect the estimated 1.6 million children, most of them under the age of 5, who die yearly from S. pneumoniae infections.

Older adults gain weight when spouse is stressed out Posted: 13 Oct 2016 08:59 AM PDT Stress isn't good for your waist line. For older married couples, the added pounds may be caused by a spouse's long-term stress levels, new research shows.

Federal school lunch guidelines lead to healthier choices, study shows Posted: 13 Oct 2016 08:17 AM PDT Researchers investigated how the nutritional content of National School Lunch Program entrées chosen by students varied across different socioeconomic and demographic groups and impacted their health. When healthier menu items replaced less healthy items, researchers found the total calories of the students' lunch choices decreased about 4 percent. Calories from fat decreased 18 percent, and those from sodium decreased by 8 percent.

Zika virus infection may prevent reinfection, study finds Posted: 13 Oct 2016 08:15 AM PDT People infected with Zika virus may not be susceptible to Zika virus again, according to the latest research. Other findings show that Zika virus is present in the blood very early during infection and remains in some tissues for a long time but is only briefly present in other tissues.

Six million dollar boost to search for new antibiotics Posted: 13 Oct 2016 06:57 AM PDT The Netherlands will be investing six million euros over the coming four years to boost research on new antibiotics.

Preventing child obesity in the next generation must start before conception Posted: 13 Oct 2016 06:57 AM PDT The key to preventing obesity in future generations is to make their parents healthier before they conceive, leading health researchers suggest.

Hormone identified that limits liver fibrosis Posted: 13 Oct 2016 06:53 AM PDT Nonalcoholic steatohepatitis (NASH) has been emerging worldwide and effective treatment, especially for liver fibrosis, is essential for improving the prognosis. A research team has identified and clarified the mechanism for a hormone that limits the fibrosis associated with NASH and cirrhosis. This discovery has potential applications for the treatment of these conditions.

New kind of local food grows in your own kitchen Posted: 13 Oct 2016 06:53 AM PDT A home appliance that grows the ingredients for a healthy meal within a week from plant cells is no longer science fiction. The first 3D-printed CellPod prototype is already producing harvests.

Novel target for diabetes drug identified as ion exchanger Posted: 13 Oct 2016 06:53 AM PDT Researchers have used nematode worms as a model to identify a new target of the type 2 diabetes drug metformin. Ion exchanger protein NHX-5 and its related protein in fruit flies are potential metformin targets, suggesting the drug controls the cellular endocytic cycle.

Smoking rises in Argentina heart attack patients as cigarettes 'among cheapest in world' Posted: 13 Oct 2016 06:52 AM PDT Levels of smoking are rising in heart attack patients in Argentina, according to a study. The findings coincide with a 100% increase in affordability in the last decade, which have made cigarettes among the cheapest in the world. Researchers also report improved treatment for heart attacks but no decrease in mortality.

Raising soda taxes may sound good, but likely to fall flat with US consumers Posted: 12 Oct 2016 03:35 PM PDT The World Health Organization (WHO) has recommended governments raise taxes on sugary drinks and increase subsidies on fruits and vegetables, in an effort to fight global obesity and diabetes.
