Posted: 26 Jul 2016 12:51 PM PDT

In recent years, numerous diseases have been tied to variations in gut microbiota. The probiotics industry targets gut and intestinal health by developing products built mostly around enzyme cultures and bacteria. But a new study suggests that the underlying health and physical forces of the gut are as important as the bacteria inside in shaping communities of intestinal microbiota, and offers insights into the problems experienced by humans with a birth defect called Hirschsprung's disease.

Posted: 26 Jul 2016 10:17 AM PDT

Researchers have studied the relationship between health insurance coverage and tobacco and alcohol use among reproductive age women in the US, and whether there were differences according to pregnancy status. The findings showed that pregnant women with insurance coverage had lower odds of alcohol use in the past month; however the odds of tobacco use were not affected. For non-pregnant women, insurance coverage resulted in higher odds of alcohol use but lower odds of using tobacco.

Posted: 26 Jul 2016 09:37 AM PDT

The number of patients hospitalized with HFpEF is now comparable to those with traditional heart failure with a reduced ejection fraction (HFrEF) and is projected to exceed that of HFrEF within the next few years. Therefore, it has become even more important to characterize the typical HFpEF patient and uncover factors that influence poor outcomes. In a new report published in the American Journal of Medicine, researchers analyzed over five million hospitalizations for acute heart failure, which provided much needed insights.

Posted: 26 Jul 2016 09:34 AM PDT

An international group of researchers has used the GTC to observe a superluminous supernova almost from the moment it occurred. It has revealed surprising behaviour, because this supernova showed an initial increase in brightness which later declined for a few days, and later increased again much more strongly. The scientists have used the data observed at the GTC and has combined them with other observations to try to explain the origin of the phenomenon.

Posted: 26 Jul 2016 09:29 AM PDT

A team of scientists has made a puzzling observation while studying the size and distribution of craters on the dwarf planet Ceres -- the largest object in the tumultuous Main Asteroid Belt between Mars and Jupiter. Scientists think Ceres' missing large craters may have been erased over time, as a result of its peculiar composition and internal evolution.

Sexual rivalry may drive frog reproductive behaviors

Posted: 26 Jul 2016 09:29 AM PDT

Biologists have long thought that some frogs evolved to mate on land instead of in water to better guard eggs and tadpoles from predation. New research now suggests that mating on land in many species might be a strategy male frogs use to ensure that their own DNA gets passed on, instead of their rivals'. Sexual selection may trump natural selection in the evolution of these reproductive behaviors.

Plasma technology can be tapped to kill biofilms on perishable fruit, foods

Posted: 26 Jul 2016 09:29 AM PDT

Americans worried about using gene editing, brain chip implants and synthetic blood

Posted: 26 Jul 2016 09:28 AM PDT

Many in the general public think scientific and technological innovations bring helpful change to society, but they are more concerned than excited when it comes to the potential use of emerging technologies to make people's minds sharper, their bodies stronger and healthier than ever before, according to a new survey. A majority of Americans would be 'very' or 'somewhat' worried about gene editing (68%); brain chips (69%); and synthetic blood (63%), while no more than half say they would be enthusiastic about each of these developments. While some people say they would be both enthusiastic and worried, overall, concern outpaces excitement.
