Model May Solve Supernova Mystery

July 23, 2015 7:00 am | by Michigan State Univ. | Videos | Comments

Giant stars die a violent death. After a life of several million years, they collapse into themselves and then explode in what is known as a supernova. How these stars explode remains a mystery. However, recent work may bring some answers to this astronomical question.

Fireflies Can Shed Light on Diagnostics

July 22, 2015 2:00 pm | by EPFL | News | Comments

In biology and medicine, we often need to detect biological molecules. Scientists have chemically tweaked the enzyme responsible for the light of fireflies to make it "sniff out" target biological molecules and give out a light signal. The result is a cheap, simple and highly accurate detection system that can change the face of the field.

E-cigs May Be Equally Addictive

July 22, 2015 2:00 pm | by ACS | News | Comments

Electronic cigarettes or “e-cigs” have been touted as a tool smokers can use to wean themselves off of traditional cigarettes, which many believe are more harmful than their “e” counterparts. But because e-cig liquid also contains nicotine and emits carcinogens, is that perception really true?

Watch the Car, Not Driver to Cut Accidents

July 22, 2015 2:00 pm | by Inside Science News Service, Joel Shurkin | News | Comments

Researchers say the key to new technologies designed to reduce accidents caused by sleepy or text-happy drivers is to watch the car, not its driver. If their research can be adapted for new cars, fatigue, a major cause of severe accidents, could be managed.

Dark Matter is Déjà-vu All Over Again

July 22, 2015 2:00 pm | by Kavli Institute for the Physics and Mathematics of the Universe at the University of Tokyo | News | Comments

Dark matter keeps galaxies, stars, our solar system and our bodies intact. Yet no one has been able to observe it, and it has often been regarded as a totally new exotic form of matter. A new theory says dark matter acts remarkably similar to subatomic particles known to science since the 1930s.

Yeast Byproduct May Save Bats

July 22, 2015 9:11 am | by Univ. of Illinois | News | Comments

A microbe found in caves produces a compound that inhibits Pseudogymnoascus destructans, the fungus that causes white-nose syndrome in bats. The find could lead to treatments that kill the fungus while minimizing disruption to cave ecosystems.
