Two Weill Cornell Medicine faculty members, Dr. David Lyden and Dr. Harel Weinstein have been elected fellows of the American Association for the Advancement of Science (AAAS).

Acinetobacter pittii (A. pittii), a type of bacteria, is evolving to become more resistant to antibiotics and is finding ways to survive in the harsh environment of the International Space Station.

An advanced software tool for analyzing DNA sequences from tumor samples has uncovered likely new cancer-driving genes, in a study led by Weill Cornell Medicine researchers.

A common, spontaneous mutation in blood stem cells, which has been linked to higher risks of blood cancer and cardiovascular disease, may promote these diseases by altering the stem cells’ programming of gene activity and the mix of blood cells they produce.

A collaboration between Weill Cornell Medicine scientists and other leaders in Alzheimer’s disease research has revealed widespread metabolic changes in the brains of individuals with Alzheimer’s disease. 

A three-year, million-dollar grant from the W.M. Keck Foundation will fund an ambitious project, led by Weill Cornell Medicine, to develop a next-generation, high-speed atomic-force microscope (AFM), capable of capturing the dynamics of proteins in unprecedented detail.

A class of proteins known as TMEM16 scramblases permit rearrangement of lipids in the cell membrane chiefly by...

Researchers at Weill Cornell Medicine and Memorial Sloan Kettering Cancer Center have identified a previously unrecognized form of hormone therapy-resistant prostate cancer, as well as a set of molecules that drive its growth. This discovery opens the door to the development of therapies that treat this specific disease.

DNA mutations are essential to the rapid development of an array of antibody-producing immune cells called B cells that collectively can recognize a vast number of specific targets. But this process can go awry in people with a mutation in a gene called SETD2, leading to a type of aggressive blood cancer.

Election to the National Academy of Sciences is one of the highest honors a scientist can receive. 

New evidence from a zebrafish model of epilepsy may help resolve a debate into how seizures originate, according to Weill Cornell Medicine and NewYork-Presbyterian investigators. 

Using cutting-edge techniques, Weill Cornell Medicine and Memorial Sloan Kettering investigators have visualized the structure of a receptor targeted by an anti-cancer immunotherapy.

Two multi-institutional teams led by Weill Cornell Medicine scientists have been awarded grant support from the Starr Cancer Consortium. Both grants will fund work applying new technologies to develop more detailed knowledge of tumor biology, with one team focusing on Hodgkin lymphoma and the other on the purity of tumor samples on pathology slides.

Investigators from Weill Cornell Medicine and Memorial Sloan Kettering Cancer Center have discovered how a drug for multiple sclerosis interacts with its targets, a finding that may pave the way for better treatments.

Using an innovative new imaging technique, researchers at Weill Cornell Medicine have revealed the inner workings of a family of light-sensing molecules in unprecedented detail and speed. 

Investigators at Weill Cornell Medicine have identified significant differences in the molecular characteristics of tumors from younger and older cancer patients across several cancer types.

Researchers at Weill Cornell Medicine have discovered how drugs can affect various membrane-spanning proteins in addition to their intended target, potentially causing unwanted side effects.

The master regulator behind the development of antibody-producing cells has been identified in a study by investigators at Weill Cornell Medicine. The findings provide new insight into the inner workings of the immune system and may help understand how tissues develop and how certain cancers arise.

A team co-led by scientists at Weill Cornell Medicine has revealed in detail how the most common primary eye cancer in adults, uveal melanoma (UM), can progress from a slow-growing, “indolent” state to a lethal metastasizing state. The discovery is a significant advance in fundamental cancer research that also suggests new strategies for treatment.

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