Chemotherapy drugs that target a common mutation in colorectal cancer rapidly lose efficacy in patients, leading to relapse. According to a new preclinical study by Weill Cornell Medicine and MD Anderson Cancer Center investigators, colorectal tumors often find multiple ways to survive treatment, including additional genetic mutations and activation of cellular pathways typically associated with inflammation and regeneration. Targeting this tumor-specific inflammatory process could enhance the efficacy of some anticancer therapies and prevent drug resistance.

When Dr. Louisa Schilling was 15 years old, she read a book called “The Brain that Changes Itself,” by Norman Doidge. Her father, who has a doctorate in microbiology and immunology, received it at a conference and it ended up in his daughter’s hands. Her immediate reaction: “I want to study the brain.”

Weill Cornell Graduate School of Medical Sciences celebrated students in the Class of 2026 for their academic achievements during its May 13 convocation ceremony.

The ceremony, hosted by Dr. Barbara Hempstead, dean of Weill Cornell Graduate School, honored students who are graduating with their master’s and doctorate degrees, as well as those who earned special awards and prizes for their accomplishments in research, scholarship and service. The ceremony also recognized exemplary graduate school faculty.

All life forms need to continuously adapt to temperature changes to survive. Now, Weill Cornell Medicine investigators studying a bacterial protein have identified a new mechanism of sensing cold temperatures. The finding points to the possibility that this same type of mechanism exists in other organisms, including humans, and may have relevance for disorders involving faulty temperature regulation.

A pilot program aimed at reducing Medicaid drug spending has limitations, according to a multi-institutional research team including faculty from Weill Cornell Medicine.

Weill Cornell Medicine investigators have “reverse engineered” ketamine’s antidepressant effects to identify potential new strategies for treating depression.

While recreational cannabis laws have significantly reduced arrests for cannabis possession and sales, racial disparities in arrests still exist, according to a new study from Weill Cornell Medicine, Instituto Tecnológico Autónomo de México and The University of Texas at Austin. The authors suggest that recreational cannabis laws do not fully resolve underlying systemic inequities.

Rows of poster boards filled the Griffis Faculty Club at Weill Cornell Medicine, showcasing research ranging from cancer immunology and microbiome science to the emerging field of space biology. Standing beside them, graduate students explained months of work in a matter of minutes, fielding questions from judges, faculty and peers.

Nerve fibers within melanomas can slow the growth of these tumors, according to a study led by Weill Cornell Medicine investigators. The findings help clarify the emerging field of cancer neuroscience and may inform future therapeutic strategies.
