Using tiny solar-panel-like cells surgically placed underneath the retina, scientists have devised a system that may someday restore sight to people who have lost vision because of certain types of degenerative eye diseases.

Having natural habitat in farming areas that supports ladybugs could help increase their abundance in crops where they control pests and help farmers reduce their costs, says a new study.

Thin models have been increasingly blamed for promoting unhealthy body images.

Scientists have made a key discovery in cell signaling that is relevant to the fight against melanoma skin cancer and certain other fast-spreading tumors.

A review article that examines what's known about regenerative biology and applies it to regenerative medicine. Perhaps this knowledge could one day be used to regrow lost body parts.

An outbreak of the exotic disease chikungunya is likely to hit New York City, scientists project.

People walking normally, women tottering in high heels and ostriches strutting all exert the same forces on the ground despite very differently-shaped feet, according to new research. The finding suggests that prosthetic lower limbs and robots' legs could be made more efficient by making them less human-like and more like ...

Jobs, livelihoods and ecotourism industries can benefit from having a diverse supply of weed-eating fish on the world's coral reefs, marine researchers say.

The team of researchers from University of Nevada’s Geodetic Laboratory in Reno and ...

[ Watch the Video ] Every second, lightning flashes some 50 times on Earth. Together these discharges coalesce and get stronger, creating electromagnetic waves circling around Earth, to create a beating pulse between the ground and the lower ionosphere, about 60 miles up in the atmosphere. This electromagnetic signature, known as ...

Brain networks may avoid traffic jams at their busiest intersections by communicating on different frequencies, researchers have learned.
