Intensive blood pressure management may save lives, landmark study shows Posted: 11 Sep 2015 07:44 PM PDT A lower blood pressure target of 120 mm Hg greatly reduces cardiovascular complications and deaths in older adults, new research shows. The groundbreaking results of this important trial is expected to impact the way physicians across the United States and Puerto Rico treat patients with high blood pressure.

Resveratrol impacts Alzheimer's disease biomarker Posted: 11 Sep 2015 01:42 PM PDT The largest nationwide clinical trial to study high-dose resveratrol long-term in people with mild to moderate Alzheimer's disease found that a biomarker that declines when the disease progresses was stabilized in people who took the purified form of resveratrol. Resveratrol is a naturally occurring compound found in foods such as red grapes, raspberries, dark chocolate and some red wines.

Predicting tornadoes months or even seasons in advance Posted: 11 Sep 2015 11:07 AM PDT A new model could help forecast tornado activity months in advance, experts say. It uses large-scale atmospheric variables like those used by weather forecasters. But instead of looking to predict a tornado on any specific day, it looks at variations in monthly and seasonal tornado activity relative to changes in atmospheric conditions over the same period.

Stroke patients fare better with private insurance than with Medicaid Posted: 11 Sep 2015 11:07 AM PDT Stroke victims who use Medicaid or are uninsured were more likely to die, stay hospitalized longer and have worse medical outcomes than patients with private insurance, a study has found.

Inside climate politics in the United States Posted: 11 Sep 2015 11:07 AM PDT The politics of climate change are often depicted as a simple battle, between environmentalists and particular industries, over government policy. That's not wrong, but it's only a rough sketch of the matter. Now a paper fills in some important details of the picture, revealing an essential mechanism that underlies the politics of the climate battle.

Cancer treatment outcomes are influenced by genetics and race, according to new study Posted: 11 Sep 2015 11:07 AM PDT A person's response to anticancer drug treatments is strongly related to their genetic ancestry, new research concludes. Notable associations were found for the drug temozolomide, which is used to treat brain tumors. Other drugs with results that suggest an association include etoposide and mitomycin, but the authors note that these results should be viewed as hypothesis generation.

Innovative imaging technique reveals new cellular secrets Posted: 11 Sep 2015 10:38 AM PDT A team of researchers has devised a novel optical technique -- a combination of structured illumination microscopy (SIM) and single-particle averaging (SPA) -- to resolve individual components of SPB duplication in living yeast cells.

Keeping gut bacteria in balance could help delay age-related diseases, study finds Posted: 11 Sep 2015 08:27 AM PDT Why do some people remain physically and mentally healthy into their 80s and beyond, while others age faster and suffer serious diseases decades earlier? New life sciences research may produce a new way to predict health declines and potentially to intervene to delay them.

Researchers identify three new fossil whale species of New Zealand Posted: 11 Sep 2015 08:27 AM PDT Paleontology researchers are continuing to rewrite the history of New Zealand's ancient whales by describing two further genera and three species of fossil baleen whales.

Wavelets improve medical imaging Posted: 11 Sep 2015 08:10 AM PDT An approach to converting the data from MRI (magnetic resonance imaging) machines, mammograms and other medical equipment gives doctors a much clearer picture of your insides and a chance to detect disease and other problems earlier, according to research.

For veterans with Gulf War Illness, an explanation for the unexplainable symptoms Posted: 10 Sep 2015 03:51 PM PDT One in four Gulf War veterans suffers from Gulf War Illness, a condition characterized by unexplainable chronic fatigue, muscle pain and cognitive dysfunction. New research finds for the first time direct evidence that the cells of Gulf War veterans cannot produce enough energy to run the body, explaining the fatigue and slow down of the body.

Eating a lot of fish may help curb depression risk -- at least in Europe Posted: 10 Sep 2015 03:50 PM PDT Eating a lot of fish may help curb the risk of depression -- at least in Europe -- suggests a pooled analysis of the available evidence. Depression affects an estimated 350 million people worldwide, and is projected to become the second leading cause of ill health by 2020.

High-intensity training delivers results for older men—but not for older women Posted: 10 Sep 2015 02:01 PM PDT High intensity training (HIT) is often recommended as a way to improve cardiovascular fitness in men and women. However, studies on these exercise regimens have focused on younger subjects. Researchers looked at whether HIT effects were the same for older males and females as those noted in younger adults and found significant differences in the results in men and women.

Cell discovery offers new strategy to attack cancer Posted: 10 Sep 2015 02:01 PM PDT By more selectively targeting cancer cells, a newly discovered method offers a strategy to reduce the length of and physical toll associated with current treatments.

Bringing 'dark data' into the light: Best practices for digitizing herbarium collections Posted: 10 Sep 2015 01:42 PM PDT North American herbaria curate approximately 74 million specimens, but only a fraction have been digitized. Imaging specimens and transcribing the related data into online databases can vastly increase available biodiversity data, allowing new discoveries. The National Science Foundation's Integrated Digitized Biocollections is facilitating an effort to unify digitization projects across the country through the development of digitization workflows. The workflows, along with details on their development, are available in a newly published article.
