As summer comes and people across America get ready to start slathering on the sunscreen, a note of caution is in order -- a little sunshine is good for you.

Research on octopuses has shed new light on how our brains store and recall memory, says Dr. Benny Hochner of the Department of Neurobiology at the Alexander Silberman Institute of Life Sciences at the Hebrew University of Jerusalem.

A new study released today offers a potential predictive technique to anticipate how individuals might behave during a psychotic episode.

A novel twist of DNA may keep viral genes tightly wound within a capsule, waiting for ejection into a host, a high-resolution analysis of its structure has revealed.

Historian George Dyson tells stories from the birth of the modern computer -- from its 16th-century origins to the hilarious notebooks of the first computer engineers.

Women in midlife underreport the number of hot flashes that they experience by more than 40 percent, and these hot flashes are linked to poor verbal memory, according to a study by researchers at the University of Illinois at Chicago.

It seems like science fiction but it's not. Boris Fritz, a senior engineer technical specialist at Northrop Grumman, tells the Low-Volume Manufacturers Association that in our lifetime, we will likely be able to hold our breath for 4 hours. Fritz and L-VMA's Dean Rotbart talk about Voxals, Utility Fog, Programmable Materials and other technologies related to additive fabrication.

Researchers from the Howard Florey Institute in Melbourne are developing new technology to create individualised brain maps that will revolutionise diagnosis of disease and enhance the accuracy of brain surgery.

Single person submersibles have been called in to help scientists retrieve samples from a lake in northern British Columbia that may hold vital clues to the history of life on Earth and on other planets.

When a mouse's immune system is deciding whether to reject a skin graft, one powerful member of a molecular family designed to provoke such a response can effectively reduce the visibility of the mouse's own cells and help the graft survive, researchers say.

Many women experience menopausal changes in their body including hot flashes, moodiness and fatigue, but the changes they don’t notice can be more dangerous.
