Princeton psychology researchers have developed a computer program that allows scientists to understand better then ever before what it is about certain human faces that makes them appear either trustworthy or fearsome.

A 'Crantastic Voyage' into the urinary tract to see just how cranberry juice works on infection. Researchers at Worcester Polytechnic Institute reveal that the juice changes the properties of bacteria that cause urinary tract infection and creates an energy barrier that prevents them from adhering to cells.

In a major leap that could transform solar power from a marginal energy source into a mainstream energy source, MIT researchers have overcome a major barrier to large-scale solar power: storing energy for use when the sun doesn't shine. Until now, solar power has been a daytime-only energy source, because storing extra solar energy for later use is prohibitively expensive and grossly inefficient. MIT researchers have hit upon a simple, inexpensive, highly efficient process for storing solar energy.

New research shows that vocal communication evolved from ancient fish species.

Cancer cells use tricks to hide from our body's immune system. One trick is to mask their presence in the body. Now, a bioengineer from Yale University has created cell-sized plastic spheres that both prep the immune system to recognize specific diseases and also increase the immune system's fighting force.

The annoying blare of an ignored car alarm may become a sound of the past if a cooperative, muteable and silent network of monitors proposed by Penn State University researchers is deployed in automobiles and in parking lots.

University of Washington scientists have found that species living in the tropical centers of the world are likely to face greater peril from global warming than those species located in cooler climates, because their tolerance for temperature increases is much narrower.

A mass grave of skeletons in southwestern Germany suggests that neighboring tribes from prehistoric times were prepared to kill their male rivals to secure their women.

Americans grow happier as they grow older, according to social science researchers at the University of Chicago, whose 33-year study is one of the most thorough examinations of happiness ever done in America.

A team of researchers, led by a Stony Brook University paleontologist, discovered the remains of what may be the largest frog ever to exist. The fossilized remains of this 16-inch, 10-pound ancient frog were found in Madagascar and link a group of frogs that lived 65-70 million years ago with frogs living today in South America.
