As scientists have questioned the reliability and validity of “pattern-matching” evidence?—?such as fingerprints, bite marks, and hair?—?prosecutors are digging in their heels and continuing to rely on it.

Chemicals commonly used in smartphone, television, and computer displays were found to be potentially toxic and present in nearly half of dozens of samples of household dust collected by a team of toxicologists led by the University of Saskatchewan (USask).

The international research team, led by USask environmental toxicologist John Giesy, is sounding the alarm about liquid crystal monomers and the potential threat they pose to humans and the environment.

New scientific research published in the journal Memory & Cognition provides evidence that a brief mindfulness meditation exercise can enhance verbal learning.

Field trials suggest public health benefit to spreading Wolbachia

Physicists have discovered a jewel-like geometric object that dramatically simplifies calculations of particle interactions and challenges the notion that space and time are fundamental components of reality. “This is completely new and very much simpler than anything that has been done before,” said Andrew Hodges, a mathematical physicist at Oxford University who has been following the work.

Recent research on what photons can tell us about health and disease; How bioluminescent you are might just say something about your health.

Scientists hope to develop new drugs that prevent virus shutting down key parts of the immune system

NASA recently detected a massive thermonuclear explosion coming from outer space.

Holds Promise for Large-Scale Hydrogen Production, Desalination

Rochester researchers have created a metallic structure so water repellent, it refuses to sink—no matter how often it is forced into water.

Scientists have created an “artificial leaf” to fight climate change by inexpensively converting harmful carbon dioxide (CO2) into a useful alternative fuel. The new technology, outlined in a paper published today in the journal Nature Energy, was inspired by the way plants use energy from sunlight to turn carbon dioxide into food.

For cocaine users, a rolled up $20 bill may be the most convenient tool for snorting the powder form of the drug. Or so it would seem from a new analysis of 234 banknotes from 18 U.S. cities that found cocaine on 90 percent of the bills tested.  

A research report published in Applied Economics has found that the number of patients with violence-related injuries treated in hospital emergency rooms is related to the price of beer.  

The paper is available online as a pdf and is from Cardiff University's Violence and Society Research Group.

Most people don't appreciate an angry look, but a new University of Michigan psychology study found that some people find angry expressions so rewarding that they will readily learn ways to encourage them.
