Energized fabrics could keep soldiers warm and battle-ready in frigid climates

EurekAlert! - Sáb, 08/19/2017 - 22:00
Soldiering in arctic conditions is tough. Protective clothing can be heavy and can cause overheating and sweating, while hands and feet can grow numb. To keep military personnel more comfortable, scientists are trying to create high-tech fabrics that heat up when powered and that capture sweat. These fabrics could conceivably be used in future consumer clothing. The researchers will present their results today at the 254th National Meeting & Exposition of the American Chemical Society.

Few women with history of breast cancer and ovarian cancer take a recommended genetic test

EurekAlert! - Jue, 08/17/2017 - 22:00
More than 80 percent of women living with a history of breast or ovarian cancer at high-risk of having a gene mutation have never taken the test that can detect it.

Yemen's Saudi-led coalition is responsible for the 'worst cholera outbreak in the world'

EurekAlert! - Jue, 08/17/2017 - 22:00
The cholera outbreak in Yemen is overwhelmingly affecting rebel-controlled areas due to Saudi-led airstrikes and blockades, according to a letter by researchers from Queen Mary University of London, published in The Lancet Global Health.

Seeking the secret ingredient in the original smallpox vaccine

EurekAlert! - Jue, 08/17/2017 - 22:00
Thanks to a secret vaccine ingredient as well as a net of worldwide researchers and successful vaccination campaigns, smallpox was finally eradicated in 1977. A new study entitled 'Revisiting Jenner's mysteries, the role of the Beaugency lymph in the evolutionary path of ancient smallpox vaccines' and published in The Lancet Infectious Diseases, provides an in-depth investigation of the mysteries associated with the development of smallpox vaccine and is a rich and interesting account of how the vaccine lymph was spread worldwide.

Novel approach to track HIV infection

EurekAlert! - Jue, 08/17/2017 - 22:00
Scientists used a novel live-cell fluorescent imaging system that allowed them for the first time to identify individual viral particles associated with HIV infection.

NJIT researchers will follow in the moon's slipstream to capture high-res sunspot images

EurekAlert! - Jue, 08/17/2017 - 22:00
While much of the research around the eclipse on Monday will focus on the effects of the Sun's brief, daytime disappearance on Earth and its atmosphere, a group of solar physicists will be leveraging the rare event to capture a better glimpse of the star itself.

Ocean channel in Bahamas marks genetic divide in Brazilian free-tailed bats

EurekAlert! - Jue, 08/17/2017 - 22:00
Brazilian free-tailed bats are expert flyers, capable of migrating hundreds of miles and regularly traveling more than 30 miles a night. But they pull up short at a narrow ocean channel that cuts across the Bahamas, dividing bat populations that last shared an ancestor hundreds of thousands of years ago.

Satellite sees the formation of eastern Pacific's Tropical Depression 13E

EurekAlert! - Jue, 08/17/2017 - 22:00
The thirteenth tropical depression of the Eastern Pacific Ocean season formed on Aug. 18. NOAA's GOES-Wet satellite captured an image of the new storm.

OU astrophysicist predicts detached, eclipsing white dwarfs to merge into exotic star

EurekAlert! - Jue, 08/17/2017 - 22:00
A University of Oklahoma astrophysicist, Mukremin Kilic, and his team have discovered two detached, eclipsing double white dwarf binaries with orbital periods of 40 and 46 minutes, respectively. White dwarfs are the remnants of Sun-like stars, many of which are found in pairs, or binaries.

To reduce postoperative pain, consider sleep -- and caffeine

EurekAlert! - Jue, 08/17/2017 - 22:00
A new preclinical study found that a brief period of extended wakefulness before surgery enhances pain and prolongs recovery time after surgery. Caffeine administration helped to reduce the harmful effects of sleep loss on subsequent surgical pain.

New bioimaging technique is fast and economical

EurekAlert! - Jue, 08/17/2017 - 22:00
A new approach to optical imaging makes it possible to quickly and economically monitor multiple molecular interactions in a large area of living tissue -- such as an organ or a small animal; technology that could have applications in medical diagnosis, guided surgery, or pre-clinical drug testing.

NASA looks at rainfall in Tropical Storm Harvey

EurekAlert! - Jue, 08/17/2017 - 22:00
Tropical Storm Harvey is now moving into the eastern Caribbean Sea. NASA's GPM core satellite examined the soaking rainfall the new tropical storm was generating along its path.

Research reveals how physical exercise protects the heart

EurekAlert! - Jue, 08/17/2017 - 22:00
A study by the University of São Paulo (USP) in Brazil, published recently in the journal Autophagy, helps to elucidate part of the mechanism whereby aerobic exercise protects the sick heart. The benefits of exercise range from prevention of cachexia -- severe loss of weight and muscle mass -- and control of arterial blood pressure to improved cardiac function, postponing a degenerative process that causes progressive heart cell death. About 70% of heart failure patients die from the condition within five years.
