To enable animals to shift their attention in response to changing circumstances, the prefrontal cortex of the brain helps keep track of which types of stimuli have recently been most relevant, suggests a preclinical study by Weill Cornell Medicine and NewYork-Presbyterian investigators. This discovery could lead to new treatments to help restore cognitive flexibility.

“Animals and people make split-second decisions about what to do in changing circumstances and what to pay attention...

Radiation therapy appears to increase or upregulate the expression of genes with mutations that induce an immune response to malignant cells, according to preclinical research by Weill Cornell Medicine and NewYork-Presbyterian investigators. The findings suggest that radiation treatment directed to tumors may help to improve a form of immunotherapy that currently has limited effectiveness.

The new research, published Jan. 21 in The...

Molecular "bookmarks," which allow cells to retain their characteristics during cell division, ensure fast reactivation of critical cell identity genes after cell division, according to investigators at Weill Cornell Medicine. The new work helps illuminate a process that has puzzled biologists for decades and suggests new strategies for modulating cell fate both for stem cell therapy and cancer treatment.

When cells undergo division, or mitosis, they temporarily shut down their normal...

For Rana Khan, earning a residency in obstetrics and gynecology at NewYork-Presbyterian/Weill Cornell Medical Center was more than just realizing a milestone in her medical education. Match Day was the culmination of a personal journey that transported Khan from medical student to cancer patient to...

Excess sugar in the blood, the central feature of diabetes, can react with immune proteins to cause myriad changes in the immune system, including inflammatory changes that promote atherosclerosis, according to a new study from scientists at Weill Cornell Medicine and University of Massachusetts Medical School.

The study, published March 15 in the journal Immunity, advances the field of diabetes research by...

A team led by scientists at Weill Cornell Medicine has made a map identifying all the different RNA molecules that are derived from each gene in the brains of mice. It is the first map that depicts this important layer of biological diversity, called isoform variation, by cell type and across brain regions for the whole genome, and it contributes to neuroscientists’ ambitious goal of an ultra-detailed atlas of the brain.

Isoform variation is a process that extends the versatility of...

The first and largest genetic association study in the Middle East revealed genetic variations that are specific to the Qatari population, a group of researchers at Qatar Foundation reported Feb. 23 in Nature Communications.

A gene linked to unusually long lifespans in humans protects brain stem cells from the harmful effects of stress, according to a new study by Weill Cornell Medicine investigators.

Studies of humans who live longer than 100 years have shown that many share an unusual version of a gene called Forkhead box protein O3 (FOXO3). That discovery led...

Patient mistrust of the healthcare system, which has come under new focus during the COVID-19 pandemic, is partly the result of an increasingly consumer-oriented healthcare system, according to a new commentary by a Weill Cornell Medicine investigator.

"Trust is the glue that holds all of healthcare together,” said lead author Dr. Dhruv Khullar, an assistant...
