silouette of a pregnant woman

The immune system of pregnant women with anxiety is biologically different from that of pregnant women without anxiety, according to new research from Weill Cornell Medicine, Johns Hopkins University School of Medicine and Columbia University Irving Medical Center investigators.

The study, published Sept. 14 in Brain, Behavior and Immunity, demonstrates that pregnant women with anxiety have higher...

Patients of Various Ethnic and Racial Backgrounds In Hospital

Black and Hispanic patients were more likely than white patients to develop a wide array of lasting symptoms and conditions after a COVID-19 diagnosis, according to a new study led by Weill Cornell Medicine and NewYork-Presbyterian investigators.

The study, published in the Journal of General Medicine on Feb. 16, adds to a growing body of evidence demonstrating profound racial and ethnic disparities in the...

A new screening tool identified roughly half of primary care patients with chronic obstructive pulmonary disorder (COPD) who could benefit from available treatments, according to a nationwide study led by investigators at Weill Cornell Medicine; NewYork-Presbyterian; the University of Michigan, Ann Arbor; National Jewish Health; the University of Minnesota and their colleagues. This performance — which they evaluated as a part of a larger, as-yet unfinished project — indicates that further...

Five teams led by Weill Cornell Medicine scientists have been awarded funding from the Starr Cancer Consortium in its 16th annual grant competition. The grants will fund research on the molecular origins and evolution of blood, bladder, breast, and colon cancers.

The Starr Cancer Consortium was established in 2006 through the philanthropy of the Starr Foundation, and includes...

Surgery that removes only a portion of one of the five lobes that comprise a lung is as effective as the traditional surgery that removes an entire lobe for certain patients with early-stage lung cancer, according to results of a phase 3 multicenter clinical trial sponsored by the Alliance for Clinical Trials in Oncology, an NCI-supported clinical trials network. The trial team was led by Dr. Nasser Altorki, chief of the Division of...

Messenger RNAs (mRNAs) contain chemical marks that are critical for antiviral defense in cells, according to a new study from researchers at Weill Cornell Medicine. The finding solves a 50-year mystery concerning the purpose of these chemical modifications and suggests that faulty mRNA modification may underlie some autoimmune and inflammatory disorders.

The researchers, whose findings appear Feb. 1 in Nature, discovered...

Interim Dean Dr. Francis Lee sent the following message Jan. 26 to the Weill Cornell Medicine community.

Dear Colleagues,

After much consideration, I am reaching out to inform you that Weill Cornell Medicine will no longer submit data to U.S. News & World Report (USNWR) for its medical school rankings.

While medical schools share many common goals, we also have unique institutional cultures and missions, as well as different pedagogical approaches and...

A protein that prepares DNA for replication also prevents the replication process from running out of control, according to a new study by Weill Cornell Medicine researchers. The work, published Jan. 5 in Molecular Cell, solves a mystery that has long puzzled biologists.

The cells of humans and all other higher organisms use a complex system of checkpoints and “licensing” proteins to...

The key to understanding how the most aggressive lymphomas arise and resist current therapies may lie in mutations that disrupt a critical natural selection process among antibody-producing B cells, according to a multi-institutional preclinical study led by Weill Cornell Medicine investigators.

Diffuse large B-cell lymphoma (DLBCL) is the most common type of non-Hodgkin lymphoma, with at least 40 percent of cases not responding to treatment. Patients with mutations in the B-cell...

A protein commonly found at high levels in lung cancer cells controls a major immunosuppressive pathway that allows lung tumors to evade immune attack, according to a study led by researchers at Weill Cornell Medicine. The discovery could hasten the development of treatments that overcome this tumor defense mechanism and improve outcomes for lung cancer patients.

In the study, which appears Jan. 9 in Nature Communications...

an elder man looking out a window deep in thought

The National Institute on Aging of the National Institutes of Health has awarded a grant to Weill Cornell Medicine to develop a screening tool and intervention for elder neglect in patients with Alzheimer’s disease and related dementias.

Approximately one in 10 Americans over the age of 60 have experienced some form of elder abuse, a broad category that encompasses financial exploitation, physical abuse, emotional abuse, neglect and more. For this study,...

Cigarette smoking is associated with worse cognitive performance among people 60 years and older, and that association is broadly the same whether or not individuals have hypertension or diabetes, according to a study from investigators at Weill Cornell Medicine and NewYork-Presbyterian. The findings, published Dec. 6 in the Journal of Alzheimer’s Disease, underscore smoking’s adverse effect on...

students posing together to take a picture

More than 160 faculty and students filled Uris Auditorium Dec. 5 to hear doctoral candidates deliver bite-size presentations of their research in an entertaining way. The catch? They had to deliver their work in three minutes or less.

Oftentimes, the theses presentations were full of puns and good humor. From likening the ability of the blood-brain barrier to block the easy passage of molecules to a strict bouncer standing imposingly at a party’s entrance, and depicting a RAS mutant...

A new method can illuminate the identities and activities of cells throughout an organ or a tumor at unprecedented resolution, according to a study co-led by researchers at Weill Cornell Medicine, NewYork-Presbyterian and the New York Genome Center.

The method, described Jan. 2 in a paper in Nature Biotechnology, records gene activity patterns and the presence of key proteins in cells across tissue samples, while...

An enzyme that defends human cells against viruses can help drive cancer evolution towards greater malignancy by causing myriad mutations in cancer cells, according to a study led by investigators at Weill Cornell Medicine. The finding suggests that the enzyme may be a potential target for future cancer treatments.

In the new...
