An enzyme called PGK1 has an unexpectedly critical role in the production of chemical energy in brain cells, according to a preclinical study led by researchers at Weill Cornell Medicine. 

A team led by researchers at Weill Cornell Medicine and the Howard Hughes Medical Institute (HHMI) Janelia Research Campus has developed and tested a high-resolution sensor for tracking the real-time dynamics of ATP levels in cells and within subcellular compartments. 

Dr. Timothy Ryan, professor of biochemistry in anesthesiology at Weill Cornell Medicine, has been elected to the prestigious National Academy of Sciences, one of the highest honors a scientist can receive.

Pound for pound, the brain consumes vastly more energy than other organs, and, puzzlingly, it remains a fuel-guzzler even when its neurons are not firing signals called neurotransmitters to each other. Now researchers at Weill Cornell Medicine have found that the process of packaging neurotransmitters may be responsible for this energy drain.

Neurons have a special mechanism that allows them to quickly boost energy production to support bursts of brain activity, according to a new study from scientists at Weill Cornell Medicine.

Dr. Ghazaleh Ashrafi, a postdoctoral associate in biochemistry at Weill Cornell Medicine, has won a 2017 Tri-Institutional Breakout Award for Junior Investigators.

A tiny tubular structure directly controls synapses, the junctions through which communication signals flow between nerve cells.

A $1.5 million grant from the W.M. Keck Foundation has established a new research and training program—called Cellular and Molecular Biophysics of Signal Transduction—to be conducted jointly by Weill Medical College and Cornell University in Ithaca. Through this new...
