Cozy clothes and yoga pants — Key source of ocean pollution

Yoga pants, Patagonia's cozy jackets, sweat-wicking athletic wear and other types of comfortable clothing all have one thing in common — these items are emerging as a major source of pollution in our waterways, lakes and oceans.

Mathematics can help explain our bodies and disease

Understanding how biological systems interact, including how the body responds to disease, is highly complex. To help biomedical scientists to understand the complexity two mathematicians have introduced a new model.

Avian flu suspected in three cases found in northern Alabama

Alabama Department of Agriculture and Industries officials are investigating three separate cases in the northern part of the state where poultry is suspected to be infected with the avian flu.

The discovery of a 400,000-year-old half skull in Portugal has offered tantalizing hints about a possible ancestor of the Neanderthals, researchers said Monday.

Do we look like our names? Psychologists think so

If you look at a person you’ve not met before how many times do you try to guess their name, or are at least unsurprised when you’re told the person’s name? It seems that humans are very good at predicting the names of people they have not met befor

New form of matter may advance quantum computing

In what could overturn our understanding of physics, a new phase of matter has been created. This is called, colloquially at least, “a time crystal.” Here atoms appear to move in a pattern that repeats in time rather than in space.
