Disability among India's elderly much higher than census estimates

EurekAlert! - Mié, 12/05/2018 - 23:00
New estimates of disability among India's elderly population, based on the ability to carry out three basic living activities -- walking, dressing, and toileting -- show that the scale of the problem is much larger than suggested by the Indian national census.

An exoplanet inflated like a balloon

EurekAlert! - Mié, 12/05/2018 - 23:00
Although helium is a rare element on Earth, it is ubiquitous in the universe. It is, after hydrogen, the main component of stars and gaseous giant planets. Despite its abundance, helium was only detected recently in the atmosphere of a gaseous giant by an international team. The team, this time led by UNIGE researchers, has observed for the first time how this gas escapes from the overheated atmosphere of an exoplanet, literally inflated with helium.

Focusing on the negative is good when it comes to batteries

Black breast cancer patients have worse outcomes than whites, despite similar treatments

EurekAlert! - Mié, 12/05/2018 - 23:00
Black women with the most common form of early breast cancer had worse outcomes than white women even after receiving equivalent care, according to a major new study led by Loyola Medicine medical oncologist Kathy Albain. Dr. Albain presented findings of the international study at the San Antonio Breast Cancer Symposium.

High-temperature electronics? That's hot

A new organic polymer blend allows plastic electronics to function in high temperatures without sacrificing performance.

Key to lifelong heart health is childhood intervention

EurekAlert! - Mié, 12/05/2018 - 23:00
Evolving evidence shows that heart healthy habits in adults are rooted in the environments we live in in early childhood, representing a window of opportunity in young children to focus on health promotion and potentially prevent disease in adulthood, according to a review paper published today in the Journal of the American College of Cardiology.

AlphaZero AI teaches itself to beat humans at their own complex games

EurekAlert! - Mié, 12/05/2018 - 23:00
The ability for computers to beat humans at their own games has long been considered a benchmark for advancement in artificial intelligence (AI).

An exoplanet loses its atmosphere in the form of a tail

EurekAlert! - Mié, 12/05/2018 - 23:00
A new study, led by scientists from the Instituto de Astrofísica de Canarias (IAC), reveals that the giant exoplanet WASP-69b carries a comet-like tail made up of helium particles escaping from its gravitational field propelled by the ultraviolet radiation of its star.

Study among first to describe work environments for nurses in Mexico

EurekAlert! - Mié, 12/05/2018 - 23:00

What does expanded Medicaid mean for the health & work lives of enrollees? A lot

EurekAlert! - Mié, 12/05/2018 - 23:00
A new study could help states that will soon expand Medicaid, or may add a work requirement, understand what might be in store. Nearly half of enrollees in Michigan's expanded Medicaid felt their physical health improved; more than a third cited better mental or dental health. Over two-thirds of those with jobs said coverage helped them do better at work; those who said their health had improved were four times as likely to say this.

New imaging tools that trace key breast cancer enzymes may help guide therapies

EurekAlert! - Mié, 12/05/2018 - 23:00
A set of emerging diagnostic tools may help identify breast cancer patients who are most likely to benefit from therapies that target important enzymes fueling a range of subtypes, including BCRA-mutated and triple negative cancers. New research from two studies conducted by researchers at the Perelman School of Medicine at the University of Pennsylvania, are presented on today at the 2018 San Antonio Breast Cancer Symposium.
