How things work: Scientists find cellular channels vital for hearing
Ending a 30-year search by scientists, researchers have identified two proteins in the inner ear that are critical for hearing, which, when damaged by genetic mutations, cause a form of delayed, progressive hearing loss. The proteins are essentially transducers: They form channels that convert mechanical sound waves entering the inner ear into electrical signals that ...

Catching platelets with NETs: Neutrophils and deep vein thrombosis
Sea cucumbers have an unusual way of defending themselves. When threatened, they ensnare their foes with sticky threads. Some even expel their own internal organs to repel attackers. Immune system cells called neutrophils sometimes do much the same: When confronted with bacteria, they unravel and shoot out their chromatin—the tightly wound mix of DNA and proteins that ...

Messenger RNA: A game-changing advance in regenerative medicine
A new way to reprogram ordinary human cells into stem cells, using RNAs, appears safer and much more efficient than current methods — and can much more readily transform stem cells into specialized cells to treat disease. We now know that scientists can take one of your cells, perhaps a skin cell, and transform it into ... Read More about Messenger RNA: A game-changing advance in regenerative medicine
