If you suffer from atrial fibrillation (AF)—a condition where disorganized electrical signals cause the heart's upper chambers to contract quickly and irregularly—your doctor may prescribe an antiarrhythmic drug. While ...

Engineers build biologically powered chip

Columbia Engineering researchers have, for the first time, harnessed the molecular machinery of living systems to power an integrated circuit from adenosine triphosphate (ATP), the energy currency of life. They achieved this ...

Imitating viruses to deliver drugs to cells

Viruses are able to redirect the functioning of cells in order to infect them. Inspired by their mode of action, scientists from the CNRS and Université de Strasbourg have designed a "chemical virus" that can cross the double ...

Cells help viruses during cell entry

Adenoviruses cause numerous diseases, such as eye or respiratory infections, and they are widely used in gene therapy. Researchers from the University of Zurich have now discovered how these viruses penetrate the cells, a ...
