Fun With Physics: How To Make Tiny Medicine Nanoballs

Scientists have long toyed with the idea of putting medicine inside microscopic capsules that could travel to hard-to-reach places inside your body. Now, researchers have come up with a method to assemble tiny nanospheres.

Nobel In Chemistry Is Shared By Two Americans

Americans Robert Lefkowitz and Brian Kobilka have won the 2012 Nobel Prize in chemistry. The Royal Swedish Academy of Sciences cited the two researchers Wednesday "for studies of G-protein-coupled receptors."

Debate Heats Up About Contentious Bird Flu Research

Because of fears that lab-altered bird flu viruses could cause a deadly pandemic if they ever escaped the lab, scientists agreed to a moratorium on mutant H5N1 flu research eight months ago. Now top scientists in the field continue the debate about the work, publishing six commentaries for and against the end of the moratorium.

Cloning and Stem Cell Discoveries Earn Nobel in Medicine

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.

Nobel Winners Unlocked Cells' Unlimited Potential

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.
