Argonne researchers have successfully laser-cooled and trapped atoms of radium — the first time this rare element has been captured in a magneto-optical trap — with an assist from an unexpected source.

A new device called TrailGuard could mean new protection for animals such as elephants, snow leopards and giant tortoises.

Researchers in Italy have created an ultrashort light pulse--a single isolated burst of extreme-ultraviolet light that lasts for only 130 billionths of a billionth of a second.

Scientists in the Northern Hemisphere have opened a new window on the universe allowing them to explore and understand the cosmos at a much higher level of precision than was previously available.

A Sandia National Laboratories research team is developing a new type of electrochemical sensor that uses a unique surface chemistry to reliably and accurately detects thousands of differing biomolecules on a single platform.

NASA’s New Horizons spacecraft has provided new data on the Jupiter system ­-- stunning scientists with never-before-seen perspectives of the giant planet’s atmosphere, rings, moons and magnetosphere.

"Lonesome George," a giant Galapagos tortoise and conservation icon long thought to be the sole survivor of his species, may not be alone for much longer, according to a multinational team of researchers headed by investigators at Yale University.

Astronomers have long thought that globular star clusters had a single "baby boom" of stars early in their lives and then settled into a quiet existence.

new study finds that exposure to a chemical component of diesel exhaust particles can compromise the ability of resistance arteries to regulate blood flow to bone marrow. Post-menopausal females, the elderly and males are most likely to be impacted

In work that could improve diagnoses of many eye diseases, MIT researchers have developed a new type of laser for taking high-resolution, 3-D images of the retina, the part of the eye that converts light to electrical signals that travel to the brain.
