A team of Weill Cornell Medicine investigators has developed a computer model that will help scientists more efficiently develop protein-destroying therapies, a newer type of treatment that is particularly promising for cancer. The study was published July 13 in Nature Communications.

Most drugs use a small molecule to render disease-causing proteins harmless, but protein-degrader therapies aim to destroy the...

Contrary to some predictions, the use of artificial intelligence (AI) agents could lead to more, not fewer, health care professionals working in the United States, according to a new article by a physician and health policy researcher at Weill Cornell Medicine who surveyed economic theory and the history of technology in health care.

Tuberculosis bacteria released into the air from infected individuals dry out to form infectious particles that are second only to measles in contagiousness. Weill Cornell Medicine investigators have discovered specific mechanisms that enable the bacteria not only to survive drying but also to generate mutations linked to antibiotic resistance. This suggests that transmission involves more than the passive movement of bacteria between people and may be a period during which the pathogen...

Weill Cornell Medicine investigators have developed a set of molecular tools to regulate the activity of specific genes in one of the most common classes of intestinal bacteria. The ability to genetically manipulate these microbes could lead to a better understanding of the role they play in human physiology and diseases.

In healthy individuals, species of Clostridia comprise half of the bacteria found in the gut. Many produce metabolites that are likely beneficial for human health and...

NEW YORK (Aug. 24, 2026)—Embracing the transformational potential of new molecular profiling and artificial-intelligence-based data processing technologies on clinical and scientific innovation, Weill Cornell Medicine has created a new research department, the Department of Systems and Computational Biomedicine. Dr. Dan Landau, an internationally recognized cancer researcher and...

Prostate tumors can rewire amino acid metabolism to override the normal brakes on cholesterol production, a process that may fuel hormone therapy resistance, according to a study by Weill Cornell Medicine investigators.

The preclinical study, published Aug. 20 in Nature Metabolism, revealed that a compound called propionyl-CoA, produced by the breakdown of amino acids isoleucine and valine during normal energy metabolism...

When Kiran Abraham-Aggarwal started his undergraduate studies at Cornell’s School of Industrial and Labor Relations (ILR), he assumed it would lead to a career in economic development or perhaps law, like many of his classmates. With an interest in advocacy and policy reform, these...

A conceptual framework like the one engineers use for characterizing the transmission of sound and electrical signals can be useful in studying how olfaction—the sense of smell—is influenced by the air flow that carries odor molecules, according to a study led by investigators at Weill Cornell Medicine and the University of Colorado—Boulder. The new approach could lead to a better understanding of how olfaction works and better designs for artificial olfaction.

Traumatic brain injury (TBI) in Pakistan is associated with a high risk of death and disability long after the initial injury, even in mild to moderate cases, according to two new studies in JAMA Network Open led by Weill Cornell Medicine researchers. While most TBIs occur in low- and middle-income countries due to road traffic accidents, long-term patient outcomes remain poorly understood.

To shed light on this critical issue, the researchers analyzed data from a trauma registry of...

Brain-resident immune cells that have reached an old-age state called “senescence” secrete a protein that causes dysfunction in other brain cells, according to a study led by investigators at Weill Cornell Medicine. The discovery sheds light on how aging impairs memory and cognition and makes the brain vulnerable to neurodegenerative disorders.

The researchers, whose ...

New York (Aug. 10, 2026)—Dr. Angela Kadenhe-Chiweshe, an accomplished pediatric surgeon and leader in complex pediatric surgery, has been appointed chief of the Division of Pediatric Surgery at NewYork-Presbyterian Komansky Children’s Hospital of Children’s Hospital of New York and Weill Cornell Medicine, effective July 1.

Dr. Kadenhe-Chiweshe will lead pediatric surgical services at NewYork-Presbyterian Komansky...

Researchers at Weill Cornell Medicine have uncovered how a key Parkinson's protein called LRRK2 shifts between inactive and active forms, revealing the structural changes that enable certain mutations to push the protein into an overactive state.  Mutations that cause LRRK2 to become abnormally active are among the most common genetic causes of...

Complex healthcare policies are often challenging to implement. That’s a reality states across the country will deal with as new Medicaid work requirements get rolled out next year.

The new federal rule, part of the Budget Reconciliation Act of 2025 (HR 1), requires adults enrolled under the Affordable Care Act (ACA) expansion of Medicaid eligibility to complete at least 80 hours per month of qualifying work or community engagement activities or meet exemption criteria to maintain...

Earlier use of a targeted radionuclide therapy delays metastatic prostate cancer progression when administered as part of a trio of drugs, according to a phase 3 clinical trial led by Weill Cornell Medicine, NewYork-Presbyterian, Memorial Sloan Kettering Cancer Center and investigators at several other institutions worldwide.

The results, published in The Lancet on Aug. 6, may change the...

During development, regional dips in oxygen levels serve as a signal that triggers the coordinated growth of heart muscle and coronary vessels, according to a study led by researchers at Weill Cornell Medicine. The findings, published online in the Proceedings of the National Academy of Sciences, could point toward innovative approaches for treating cardiovascular conditions that lead to heart failure.

“The signaling...

A protein secreted by common cancer types makes blood vessels leakier to allow metastatic tumors to form in the lungs, according to a study led by investigators at Weill Cornell Medicine and Memorial Sloan Kettering Cancer Center. The discovery could lead to new ways of monitoring and reducing lung metastasis risk in cancer patients.

The researchers, whose findings appear Aug...

A protein that can dial down oxidative stress in cells helps some cancers resist treatment with a widely used class of drugs called BTK inhibitors, according to a study led by investigators at Weill Cornell Medicine. The discovery points to a possible solution to the problem of BTK inhibitor treatment resistance.

BTK inhibitors reduce the activity of the enzyme BTK (Bruton’s Tyrosine Kinase), which has a central role in immune cells called B cells. Inhibiting BTK chokes off the ability...

An overactive immune response in the brain may play a role in Dravet Syndrome, a rare and severe genetic epilepsy that typically begins in infancy, according to Weill Cornell Medicine researchers. Children with the condition experience frequent seizures that are often difficult to control with medication and may also face developmental, cognitive and behavioral challenges. Until now, most research has focused on how a mutation in the SCN1A gene disrupts electrical signaling in the brain....
