NASA Ppotects its super heroes from space weather

Mié, 08/16/2017 - 22:00
When astronauts travel in space they can't see or even feel radiation. However, NASA's Human Research Program (HRP) is studying the effects radiation plays on the human body and developing ways to monitor and protect against this silent hazard.

Outdoor light at night linked with increased breast cancer risk in women

Mié, 08/16/2017 - 22:00
Women who live in areas with higher levels of outdoor light at night may be at higher risk for breast cancer than those living in areas with lower levels, according to a large long-term study from Harvard T.H. Chan School of Public Health. The link was stronger among women who worked night shifts.

Energy dense foods may increase cancer risk regardless of obesity status

Mié, 08/16/2017 - 22:00
While there is a proven link between obesity and certain types of cancer, less is known about how the ratio of energy to food weight, otherwise known as dietary energy density (DED), contributes to cancer risk. To find out, researchers looked at DED in the diets of post-menopausal women and discovered that consuming high DED foods was tied to a 10 percent increase in obesity-related cancer among normal weight women.

Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Mar, 08/15/2017 - 22:00
As graphene's popularity grows as an advanced 'wonder' material, the speed and quality at which it can be manufactured will be paramount. With that in mind, the research group of SungWoo Nam, assistant professor of mechanical science and engineering at Illinois, has developed a cleaner and more environmentally friendly method to isolate graphene using carbon dioxide (CO2) in the form of carbonic acid as the electrolyte solution.

Mar, 08/15/2017 - 22:00
Half of the world's farmed salmon are part deaf due to accelerated growth rates in aquaculture, new research has found. The results now offer a better understanding of the effects of a common inner ear deformity, and some specific actions to tackle this welfare issue.

Poll: Senate ACA replacement bill failure related to divisions among Republicans and parties

Mar, 08/15/2017 - 22:00
A new analysis of 27 national public opinion polls by 12 survey organizations finds the failure of the recent US Senate debate over proposals to repeal and replace the Affordable Care Act (ACA) relates to deep divisions among Republicans, and between Republicans and Democrats, on the future of the ACA. The analysis suggests the debate outcome was influenced by a substantial growth in public support for the principle that the federal government should ensure that all Americans have health insurance coverage.

Daily e-cigarette users had highest rates of quitting smoking

Mar, 08/15/2017 - 22:00
Among US adults who were established smokers in the past five years, those who use e-cigarettes daily were significantly more likely to have quit cigarettes compared to those who have never tried e-cigarettes. Over half of daily e-cigarette users had quit smoking in the past five years, compared to 28 percent who had never tried e-cigarettes. This is one of the first studies to reveal the patterns of cessation prevalence among e-cigarette users.

Scientists discover powerful potential pain reliever

Mar, 08/15/2017 - 22:00
Chemists have discovered a powerful pain reliever that acts on a previously unknown pain pathway. The compound is as effective at relieving neuropathic pain in injured mice as a drug widely used for pain relief called gabapentin. If they can demonstrate that it is safe, effective and nonaddictive in humans -- a process that typically takes years -- the discovery could address one of today's biggest public health challenges: the opioid abuse epidemic.
