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.

Scientists unveil the functional landscape of essential genes

A team of scientists at Whitehead Institute and the Broad Institute of MIT and Harvard have systematically evaluated the functions of more than 5,000 essential human genes using a novel, pooled, imaged-based screening method. ...

Extreme salt stress triggers leaf movement

Plant leaves can cope with much higher salt concentrations than roots. The underlying mechanism may help to develop more salt-tolerant crops.

Ion channel

Ion channels are pore-forming proteins that help establish and control the small voltage gradient across the plasma membrane of all living cells (see cell potential) by allowing the flow of ions down their electrochemical gradient. They are present in the membranes that surround all biological cells. The study of ion channels is known as channelomics and involves many scientific techniques such as voltage clamp electrophysiology (in particular patch clamp), immunohistochemistry, and RT-PCR.
