researcher examining psychedelic mushrooms

The psychedelic drugs LSD and psilocybin activate serotonin receptors on brain cells in a way that reduces the energy needed for the brain to switch between different activity states, according to a study led by Weill Cornell Medicine researchers.

The study, which appeared Oct. 3 in Nature Communications, offers insight into the mechanism of these drugs’ effects—effects that many hope can someday be harnessed...

colonies of a fungus

The presence of some fungal species in tumors predicts—and may even help drive—worse cancer outcomes, according to a study from Weill Cornell Medicine and Duke University researchers.

The study, which appears Sept. 29 in Cell, provides a scientific framework to develop tests that delineate specific fungal species in tumors that are relevant for prediction of cancer progression and therapy. The results also point to...

A new screening tool for electronic medical records accurately identifies patients who are at high risk of having or developing progressive scarring of the lungs, a condition called idiopathic pulmonary fibrosis, according to investigators from Weill Cornell Medicine, NewYork-Presbyterian, the University of Chicago, Brigham and Women’s Hospital and Mayo Clinic.

Idiopathic pulmonary fibrosis (IPF) is usually fatal, in part because it tends to be diagnosed late in its course, when...

By analyzing key enzymes in a new way, an international team led by researchers at Weill Cornell Medicine has discovered how a well-known signaling molecule can either stimulate or suppress tumor growth depending on where it’s produced. The work, published Sept. 27 in Cell Reports, reveals a new aspect of tumor cell biology, and points to a promising strategy for treating many types of...

An advanced software tool for analyzing DNA sequences from tumor samples has uncovered likely new cancer-driving genes, in a study led by Weill Cornell Medicine researchers.

In the study, published Sept. 26 in Nature Communications, the researchers designed the software, known as CSVDriver, to map and analyze the locations of large mutations, known as structural variants (SVs), in tumor DNA datasets. They then applied the...

A common, spontaneous mutation in blood stem cells, which has been linked to higher risks of blood cancer and cardiovascular disease, may promote these diseases by altering the stem cells’ programming of gene activity and the mix of blood cells they produce, according to a study co-led by investigators at Weill Cornell Medicine, NewYork-Presbyterian, the New York Genome Center...

Aggregates of the protein alpha-synuclein spread in the brains of people with Parkinson’s disease through a cellular waste-ejection process, suggests a new study led by Weill Cornell Medicine researchers.

During the process, called lysosomal exocytosis, neurons eject protein waste they cannot break down and recycle. The discovery, published Aug. 22 in Nature Communications, could resolve one of the mysteries...

Weill Cornell Medicine investigators have identified definitive biological links between African ancestry and disease processes that affect an aggressive cancer type called triple-negative breast cancer (TNBC). Their analysis of TNBC tumors from a diverse patient population yielded a large set of genes whose expression differed in patients with African ancestry compared with patients with European ancestry.

In the...

A collaboration between Weill Cornell Medicine scientists and other leaders in Alzheimer’s disease research has revealed widespread metabolic changes in the brains of individuals with Alzheimer’s disease. The findings could lead to the development of new treatments aimed at ameliorating the metabolic effects of the disease.

For the study, published July 13 in Alzheimer’s and Dementia, the investigators...

An easy-to-use device for infant circumcision has proved to be safe in an international randomized controlled clinical trial led by Weill Cornell Medicine physician-scientists. The results suggest that the device could boost efforts to increase circumcision rates and prevent HIV in low-resource settings where early infant circumcision is not widespread. 

The trial, whose results were...

Tampa FL (Sept. 13, 2022) – Artificial intelligence may soon help doctors diagnose and treat diseases, including cancer and depression, based on the sound of a patient’s voice, as 12 leading research institutions launch a landmark National Institutes of Health-funded academic project that may establish voice as a biomarker used in clinical care.

The University of South Florida in Tampa, FL, is the lead institution on the project in collaboration with...

NEW YORK (Sept. 9, 2022)—Weill Cornell Medicine was awarded a $61.9 million grant from the National Institutes of Health’s National Center for Advancing Translational Sciences (NCATS) to continue funding its Clinical and Translational Science Center (CTSC) until 2027. It is the largest federal grant ever awarded to Weill Cornell Medicine and the fourth consecutive time this initiative has been funded by the NIH, representing...

Immune cells called group 3 innate lymphoid cells (ILC3s) play an essential role in establishing tolerance to symbiotic microbes that dwell in the human gastrointestinal tract, according to a study led by researchers at Weill Cornell Medicine.

The discovery, reported Sept. 7 in Nature, illuminates an important aspect of gut health and mucosal immunity—one that may hold the key to better treatments for inflammatory bowel...

A new preclinical model for thymic cancer developed by Weill Cornell Medicine investigators has revealed insights into how a common mutation found in thymic epithelial tumors sparks their formation. The model may help speed the development of targeted therapies for cancer of the thymus, a gland that makes immune cells that help protect the body from infections.

In a study published Aug. 29 in the Journal of...

A new study from Weill Cornell Medicine investigators shows that cultural values and social support may influence a caregiver’s burden, self-efficacy and depressive symptoms. These findings suggest interventions aimed at buffering the negative effects of care-related stress should reinforce the importance of social connections. 

In a study reported in the July 2022 issue of the Journals...
