The Nobel Prize in Physiology or Medicine was announced Monday in Sweden to two scientists: John Gurdon of England and Shinya Yamanaka of Japan. The two will share the prize for their landmark work on stem cells. These cells hold great promise for treating human disease but they are also a source of controversy.
John Gurdon and Shinya Yamanaka discovered that every cell in our body — from skin and heart to brain and lung — can reinvent itself and become any other cell type. These stem cells have vast potential for drug development, for many diseases, like Alzheimer's, muscular dystrophy and diabetes.
British researcher John Gurdon and Shinya Yamanaka of Japan have won this year's Nobel Prize in medicine or physiology. They won for the discovery that mature cells can be reprogrammed into stem cells.
The ice covering the Arctic Ocean was at a record low, in keeping with a sharp warming trend in the far north. At the same time, the amount of the ocean around Antarctica covered by sea ice hit a record high. It's winter in Antarctica when it's summer in the Arctic. But why in a warming world is wintertime ice growing?
A new dinosaur species was identified this week called Pegomastax, or "thick-jawed reptile." The dinosaur's defining feature is its fangs, which make it look like a fearsome cross between a porcupine and a chicken.
As a multibillion-dollar environmental effort gets underway, the state has to figure out what the landscape used to look like. Ninety-seven percent of the original wetlands in the inland delta near the San Francisco Bay are gone, so California is turning to historians for help.
Scientists have been using whole genome sequencing for over a decade, but it has yet to become a routine tool in the clinic. Two separate research groups showed progress in making diagnoses using in-depth genome analysis.
