When a scrappy team of scientists joined forces in the late 1990s, they sought to identify genetic mutations that could have an outsized impact on the treatment of human disease. At the time, that ...

Mutated variants of a particular ion channel cause difficult-to-treat epilepsy. A study published in the journal Nature now shows that a commonly used anesthetic drug, propofol, can restore the ...

Researchers have gained new insights into an ion channel from algae. These insights could help optogenetics realize its full potential in the future. Subscribe to our newsletter for the latest ...

(Nanowerk Spotlight) Biological brains compute using ions, not electrons. Every signal between neurons depends on charged atoms passing through protein channels embedded in cell membranes, a system ...

A new study has unveiled a precise picture of how an ion channel found in most mammalian cells regulates its own function with a 'ball-and-chain' channel-plugging mechanism. The findings boost the ...

Researchers decipher the function of an ion channel involved in cellular degradation processes and create new possibilities for Parkinson’s therapies. Washbowls, bathtubs, and sinks are all fitted ...

When you scratch an itch, something tells your brain when to stop. That moment of relief, when scratching feels "enough," is not accidental. Scientists have now identified a key molecular and neural ...

Cells send electrical impulses throughout the body, but electrophysiologists struggled to tune into these signals until the patch clamp technique was developed. Although biophysicist Bernard Katz from ...
