A metabolite called colanic acid can extend the lifespan of worms as much as 50%. New research uses optogenetics to clarify that discovery.

Norepinephrine-producing neurons in the locus coeruleus produce attention focus, impulse control via two distinct connections to prefrontal cortex.

Brains recognize a smell based on which cells fire, in what order – the same way you recognize a song based on its pattern of notes. How much can you change the 'tune' and still know the smell?

The Feng lab has developed a next-generation optogenetic system for non-invasive stimulation of neurons.

Researchers have mapped the brain mechanisms that drive movement in grooming fruit flies. That could help fight Parkinson's disease and OCD.

A new feat in optogenetics used red and green light to raise and lower the speed of beating heart cells.

"Optogenomics" could one day offer the ability to manipulate our genomes, potentially upending treatment for cancer and other diseases.

New optogenetic technique could help restore limb movement, treat muscle tremor.
