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.

Nearly 200 scientists, investors and industry representatives attended Weill Cornell Medicine’s 2025 Biomedical Innovation Conference April 1, sharing their startup journeys and experiences nurturing biomedical advances into health care products and companies.

Dr. Helen Boucher, dean of Tufts University School of Medicine, delivered the Women in Medicine and Science lecture for Weill Cornell Medicine’s seventh annual Diversity Week.   

Weill Cornell Medicine’s Celebration of Diversity honored leaders who go beyond their official roles, dedicating time, energy and empathy to build inclusive environments. The ceremony, part of the institution’s seventh annual Diversity Week, was held April 7 in Griffis Faculty Club.

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.

Diversity is a tool for truth, not political agendas, said Vincent D. Rougeau,  president of the College of the Holy Cross, in a keynote address.

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.

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.

Students in the Class of 2025 learned on Match Day where they will be doing their internship and residency training—setting the stage for the next several years of their medical careers and lives.

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.

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.

People with Crohn’s disease and related joint inflammation linked to immune system dysfunction have distinct gut bacteria or microbiota, with the bacterium Mediterraneibacter gnavus being a potential biomarker, according to new study by Weill Cornell Medicine researchers.

A new study unveils a precise picture of how an ion channel found in most mammalian cells regulates its own function with a “ball-and-chain” channel-plugging mechanism. The findings could lead to new drugs that target these channels to treat disorders such as epilepsy and hypertension.
