New Approach Could Treat MS, Other Autoimmune Diseases

Researchers trying to find a way to treat multiple sclerosis think they've come up with an approach that could not only help patients with MS, but those with a range of so-called autoimmune diseases, from type-1 diabetes to psoriasis, and perhaps even food allergies. So far it's only worked in mice, but it has worked especially well.

Scientists Make Progress in Tailor-Made Organs Using Body's Own Cells

Tissue engineers are building organs using the body's own cells and letting the body do most of the work. At Wake Forest University in North Carolina, for example, where the first bladders were developed, researchers are working on kidneys, livers and more. Labs in China and the Netherlands are among many working on blood vessels.

Medical Breakthroughs Give New Hope Across the Board

Major medical advancements in research this century are transforming diseases and common health problems bringing hope to millions. From alzheimers to glaucoma, MS to migraines, and diabetes to dental crowns, breakthroughs are rapid and real. Here are nine developments set to change the medical landscape this decade.

Mars Rover Beats the Odds, Lands on Red Planet, Beams Back Photos

Facing unfavorable odds, the U.S. scored a huge victory, sticking a landing on the surface of Mars early Monday, setting down the largest and most sophisticated mobile laboratory ever deployed, which is now beaming back photos of the red planet. NASA ground control engineers flew into a frenzy of high-fives, hugs and cheers after NASA's Curiosity rover survived a perilous seven-minute plunge to the surface of the red planet.

Early Relic Suggests First Americans Were Stone Age Europeans Who Traveled West 20,000 Years Ago

Archaeologists have long held that North America remained unpopulated until about 15,000 years ago, when Siberian people walked or boated into Alaska and then moved down the West Coast. But a dark, tapered stone blade, found near the mouth of the Chesapeake Bay, turned out to be 22,000 years old, suggesting that its makers probably paddled from Europe and arrived in America thousands of years ahead of the western migration.

In Girl's Last Hope, Altered Immune Cells Beat Leukemia

It is hard to believe, but last spring Emma, then 6, was near death from leukemia. She had relapsed twice after chemotherapy, and doctors had run out of options. Desperate to save her, her parents sought an experimental treatment at the Children's Hospital of Philadelphia, one that had never before been tried in a child, or in anyone with the type of leukemia Emma had.
