A protein that prepares DNA for replication also prevents the replication process from running out of control, according to a new study by Weill Cornell Medicine researchers.

A mitochondrial gene plays a crucial role in genetic susceptibility to Zika, Dengue, and SARS-CoV-2 infections, a study by Weill Cornell Medicine investigators showed.

Disruption of the circadian clocks that keep the body and its cells entrained to the 24-hour day-night cycle plays a critical role in weight gain, according to a pair of studies by Weill Cornell Medicine investigators.  

SARS-CoV-2 infections of women in late pregnancy frequently spread to their placentas and led to inflammation.

The SARS-CoV-2 virus can infect specialized pacemaker cells that maintain the heart’s rhythmic beat, setting off a self-destruction process within the cells, according to a preclinical study co-led by researchers at Weill Cornell Medicine, NewYork-Presbyterian and NYU Grossman School of Medicine.

Tumors can use an enzyme called ART1 to thwart antitumor immune cells, making the enzyme a promising new target...

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.

Researchers at Weill Cornell Medicine have shown that they can record the high-speed motions of proteins while correlating their motion to function.

The study of human pluripotent stem cells, which can develop into any cell type in the body, is providing Weill Cornell Medicine and NewYork-Presbyterian investigators with new insights into the virus that causes COVID-19 and how it may infect organs such as the pancreas and liver.

A new technology developed by Weill Cornell Medicine and Max Planck Institute for Medical Research scientists allows the controlled, on-and-off “switching” of neural receptors with unprecedented efficiency and precision. 

An enzyme found in brain cells can break apart the precursors to plaques that accumulate in the organ and cause toxicity in Alzheimer’s disease, according to a new study led by Weill Cornell Medicine scientists.
