Weill Cornell Medicine researchers have found that intracranial hemorrhages, or "brain bleeds" caused by a ruptured blood vessel in the brain, double a person’s risk of developing dementia later in life.

While the connection between dementia and ischemic strokes caused by clots that block blood supply to the brain has received more attention, the...

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, Memorial Sloan Kettering Cancer Center and University of California San Diego Health. Clots are the second-leading cause of death among cancer patients with advanced disease or aggressive tumors.

While blood clots usually form to stop a wound from bleeding, cancer patients can form clots without...

Almost 50 million Americans—disproportionately in rural areas—must drive 25 miles or more to access a gastroenterologist for diagnosis and treatment of issues involving the digestive system, according to a study from Weill Cornell Medicine researchers.

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. The resulting atlas advances basic research on the biology of the pancreas and could lead to new treatment strategies for diabetes and other pancreatic diseases.

New York (January 31, 2025)—Reflecting the ongoing evolution of science toward interdisciplinary collaboration, Weill Cornell Medicine has created a new Department of Biochemistry and Biophysics, combining expertise from its Departments of Biochemistry and of Physiology and Biophysics. Dr. Samara Reck-Peterson, a nationally renowned mechanistic cell biologist, has been recruited to lead the department, which marshals biochemists, biophysicists and experts in...

Women who go on to develop postpartum depression (PPD) may have characteristic levels of neuroactive steroids, molecules derived from the hormone progesterone, in their blood during the third trimester of pregnancy, according to a new study by researchers at Weill Cornell Medicine and the University of Virginia School of Medicine. These molecules influence the brain’s stress response and emotional regulation.

The findings...

Weill Cornell Medicine investigators have identified in a preclinical model a specific brain circuit whose inhibition appears to reduce anxiety without side effects. Their work suggests a new target for treating anxiety disorders and related conditions and demonstrates a general strategy, based on a method called photopharmacology, for mapping drug effects on the brain.

In their study, published Jan. 28 in Neuron...

The Translational Research Institute for Pain in Later Life (TRIPLL), a New York City-based center to help older adults prevent and manage pain, has been awarded a five-year, $5 million renewal grant from the National Institute on Aging (NIA).

The institute, formed in 2009 as one of the Edward R...

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.

The findings, published Jan. 21 in Pain, stretched across all socioeconomic groups, and suggest that communities of color may be...

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.

The study, published Jan. 16 in the Journal of Urban Health, found that 97% of people who...

A group of immune proteins called the inflammasome can help prevent blood stem cells from becoming malignant by removing certain receptors from their surfaces and blocking cancer gene activity, according to a preclinical study by Weill Cornell Medicine investigators.

The study, published Jan. 2 in Nature Immunology, may lead to therapies that target the earliest stages of cancer. The findings bolster the idea that the...

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. However, these pharmacies appear less used in Medicare than in other market segments. These PBMs are part of integrated health care conglomerates that own insurance companies and pharmacies, which may create conflicts of interest.

When Dr. Tamatha Fenster received a call from a young patient requesting a refill on her Oxycodone for pelvic pain, she was faced with a dilemma: letting the patient remain in pain or refill a prescription and perpetuate an opioid dependency.

With few other pain-relief options, she refilled the prescription. “I had to think of an alternative for pelvic pain for women,” said Dr. Fenster, assistant professor of clinical...

Beneficial gut microbes and the body work together to fine-tune fat metabolism and cholesterol levels, according to a new preclinical study by investigators from Weill Cornell Medicine and the Boyce Thompson Institute at Cornell University’s Ithaca campus.

The human body has co-evolved with the beneficial microbes that live in the gut (termed the microbiota), resulting in mutually favorable relationships that aid in the digestion of food and...

Dr. Jim Castellanos (M.D. ’20, Ph.D. ’18), an instructor in anesthesiology at Weill Cornell Medicine, has been selected as a 2024 Hanna H. Gray Fellow by the Howard Hughes Medical Institute (HHMI).

Dr. Castellanos is one of 25 early-career scientists in the United States selected this year for this prestigious program, which aims to recruit and retain...

People with diabetes who were taking GLP-1 receptor agonist drugs such as tirzepatide and semaglutide had significantly lower rates of hospital readmission, wound re-opening and hematoma after surgery, according to a large study led by investigators at Weill Cornell Medicine, Columbia University Vagelos College of Physicians and Surgeons and NewYork-Presbyterian.

Weill Cornell Medicine has received a five-year, $2.3 million grant from the Centers for Disease Control and Prevention to improve equitable access to care, quality of life and survival outcomes for young people with all stages of breast cancer.

The grant will enable Weill Cornell Medicine to enhance care coordination for patients and caregivers to optimize support of physical, mental, emotional, social and spiritual needs, while offering culturally relevant resources and targeted...

The hormone estrogen regulates binge drinking in females, causing them to “pregame”—consume large quantities of alcohol in the first 30 minutes after it’s offered, according to a preclinical study led by scientists at Weill Cornell Medicine. The study establishes, for what is thought to be the first time, that circulating estrogen increases binge alcohol consumption in females and contributes to known sex differences in this behavior.

Immune cells in the brain called microglia can partially break down large amyloid plaques characteristic of Alzheimer’s disease by latching on to them, forming a sort of external stomach and releasing digestive enzymes into the space, according to a preclinical study by Weill Cornell Medicine investigators. The findings could ultimately lead to therapies that boost the ability of microglia to break down amyloid plaques.
