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.

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.

Working toward more effective tuberculosis (TB) vaccines, researchers have developed two strains of mycobacteria with "kill switches" that can be triggered to stop the bacteria after they activate an immune response.

Adding engineered human blood vessel-forming cells to islet transplants boosted the survival of the insulin-producing cells and reversed diabetes in a preclinical study led by Weill Cornell Medicine investigators. 

In their effort to answer a decades-old biological question about how the hepatitis B virus is able to establish infection of liver cells, research led by Weill Cornell Medicine, Memorial Sloan Kettering Cancer Center and The Rockefeller University identified a vulnerability that opens the door to new treatments.

A multi-national, multi-institutional study led by Weill Cornell Medicine investigators found little natural resistance to a new HIV therapy called lenacapavir in a population of patients in Uganda.

Two Weill Cornell Medicine physician-scientists, Dr. Niroshana Anandasabapathy and Dr. Rohit Chandwani, have been elected members of the American Society for Clinical Investigation (ASCI) for 2025.

Blood clots form in response to signals from the lungs of cancer patients—not from other organ sites, as previously thought—according to a preclinical study by Weill Cornell Medicine.

The distinct population of endothelial cells that line blood vessels in the insulin-producing “islets” of the human pancreas have been notoriously difficult to study, but Weill Cornell Medicine investigators have now succeeded in comprehensively detailing the unique characteristics of these cells. 

Weill Cornell Medicine investigators have identified in a preclinical model a specific brain circuit whose inhibition appears to reduce anxiety without side effects. 

Non-white communities had significantly less access to opioid medications commonly prescribed for moderate to severe pain than white communities over the decade beginning in 2011, according to a study by Weill Cornell Medicine researchers.

Drs. Steven Josefowicz, Ekta Khurana and Kristen Pleil were among 400 early-career scientists and engineers to receive the Presidential Early Career Award for Scientists and Engineers.

The overwhelming majority of those in New York City who obtained a naloxone kit to counteract opioid overdose had a high need for the drug, according to a new study by Weill Cornell Medicine investigators and the New York City Department of Health and Mental Hygiene.

Weill Cornell Medicine researchers have found that pharmacy benefit managers (PBMs)—organizations that negotiate access to medicines for most patients in the United States—steer patients to use their own pharmacies.

Beneficial gut microbes and the body work together to fine-tune fat metabolism and cholesterol levels, according to a new preclinical study.
