A new study from Weill Cornell Medicine provides insights into how cells maintain the tiny end caps of chromosomes as they divide, a key process in keeping cells healthy. Using yeast, the researchers reveal protein interactions that could explain how the enzyme telomerase is tightly regulated to prevent cells from dividing uncontrollably or aging prematurely.

Bacteria naturally present in the human intestine, known as the gut microbiota, can transform cholesterol-derived bile acids into powerful metabolites that strengthen anti-cancer immunity by blocking androgen signaling, according to a preclinical study led by Weill Cornell Medicine investigators.

As chair, Dr. Ehrt seeks to build on the department’s already robust national and international footprint in tuberculosis research and expand its portfolio in other areas of research and innovation.

A new, error-corrected method for detecting cancer from blood samples is much more sensitive and accurate than prior methods and may be useful for monitoring disease status in patients following treatment, according to a study by Weill Cornell Medicine and New York Genome Center investigators.

New research from Weill Cornell Medicine has uncovered a surprising culprit underlying cardiovascular diseases in obesity and diabetes—not the presence of certain fats, but their suppression.

Dr. Timothy Ryan has been named one of eight academic principal investigators to participate in the SPARK NS Translational Research Program, 2025 cohort.

A Phase I clinical trial demonstrated that a targeted approach to treating a deadly brain tumor in children called diffuse intrinsic pontine glioma (DIPG) is safe, reported Weill Cornell Medicine and Memorial Sloan Kettering Cancer Center investigators.

Linoleic acid, an omega-6 fatty acid found in seed oils such as soybean and safflower oil, and animal products including pork and eggs, specifically enhances the growth of the hard-to-treat “triple negative” breast cancer subtype, according to a preclinical study led by Weill Cornell Medicine investigators. 

Knocking out a single gene reprograms part of the large intestine to function like the nutrient-absorbing small intestine, according to a new study by Weill Cornell Medicine investigators.

A multi-institutional study co-led by Weill Cornell Medicine finds that pregnancy may offer some protection from developing Long COVID— a condition lasting for months after a person recovers from SARS-CoV-2 infection.

Leveraging the power of AI and machine learning technologies, researchers at Weill Cornell Medicine developed a more effective model for predicting how patients with muscle-invasive bladder cancer will respond to chemotherapy.

With a mission to understand how nutrition and metabolism impact the body’s ability to control cancer, four leading research institutions have united under the Weill Cancer Hub East, an innovative, collaborative partnership that aims to transform cancer treatment.

An program developed by NewYork-Presbyterian and Weill Cornell Medicine that combines physician telehealth with home health care administered by paramedics helps reduce hospital readmissions for patients with heart failure and other chronic conditions, according to new research.

Weill Cornell Medicine researchers found that restricting telehealth prescriptions for opioid use disorder could prevent thousands from accessing buprenorphine, a medication that helps people recover from addiction.

Dr. Jim Hu was awarded a grant from the Prevent Cancer Foundation to support and innovate initiatives aimed at reducing misinformation, improving patient decision making, and addressing disparities in prostate cancer diagnosis and treatment.

A new Weill Cornell Medicine and Oregon Health & Science University co-authored study provides critical insight for the development of a vaccine that can more effectively block the spread of cytomegalovirus, or CMV, across the placenta to babies before they are born.

A person’s “bioenergetic age” — or how youthfully their cells generate energy — might be a key indicator of whether they’re at risk of developing Alzheimer’s disease, new research from Weill Cornell Medicine shows.

Tuberculosis bacteria rely on a family of genes that help them survive the challenging journey from one person’s lungs to another person’s during coughing, sneezing or talking, according to researchers from Weill Cornell Medicine and the Massachusetts Institute of Technology.

Dr. Jacqueline Burré and a team of researchers were recently awarded an R01 grant from the National Institute of Neurological Disorders and Stroke expected to be $3.9 million over five years. 

A single molecular switch is essential for blood stem cells to enter an activated, regenerative state in which they produce new blood cells, according to a preclinical study led by Weill Cornell Medicine investigators.
