Molecules found in mucus could prevent cholera infection

MIT researchers have identified molecules found in mucus that can block cholera infection by interfering with the genes that cause the microbe to switch into a harmful state.

Pacemaker channel discovery could lead to better heart drugs

The mechanism by which fat-related molecules called lipids regulate pacemaker ion channel proteins, which help control the heart rhythm, has been revealed in a study from researchers at Weill Cornell Medicine.

Key regulator of cell growth deciphered

The mTOR protein plays a central role in cell growth, proliferation and survival. Its activity varies according to the availability of nutrients and some growth factors, including hormones. This protein is implicated in several ...

Lipid expansion microscopy uses 'power of click chemistry'

Lipids—fats—make great walls for cells and organelles because they are water resistant and dynamic. But those same characteristics also make them hard to image using expansion microscopy, a technique that works for magnifying ...

The cell sentinel that neutralizes hepatitis B

The hepatitis B virus (HBV) is responsible for one of the most serious and common infectious diseases. Transmitted through biological fluids, it attacks the liver cells. The chronic form of the disease can lead to serious ...
