Weill Cornell Medicine researchers have discovered a mechanism that ovarian tumors use to cripple immune cells and impede their attack—blocking the energy supply T cells depend on. 

A new artificial intelligence-based system can accurately assess the chromosomal status of in vitro-fertilized (IVF) embryos using only time-lapse video images of the embryos and maternal age, according to a study from investigators at Weill Cornell Medicine.

On Aug. 13, the 106 first-year medical students in Weill Cornell Medical College's Class of 2028 received their short white coats during the annual White Coat Ceremony, officially marking the beginning of their medical education.

An iron-binding drug that is already approved for treatment of other diseases could provide a novel way to attack ovarian tumors, according to a new study led by Weill Cornell Medicine researchers.

Vaccinating mothers against respiratory syncytial virus (RSV) during late pregnancy to protect their newborns is not associated with an increased risk of preterm birth or other poor outcomes, according to a study by Weill Cornell Medicine and NewYork-Presbyterian investigators.

By teasing out the biological mechanisms underlying postpartum mental health disorders, investigators at Weill Cornell Medicine are laying the groundwork for new ways to detect and treat women at risk. 

Researchers find that including BRCA1 testing at the time of obstetrical prenatal carrier screening may be a cost-effective way to identify those at risk of certain cancers.

When Nila Charles was diagnosed with breast cancer, she was the mother of two young children, working long hours and caring for a family member who was also diagnosed with cancer.

Dr. Jeannine Gerhardt, an assistant professor of stem cell biology in obstetrics and gynecology and in reproductive medicine at Weill Cornell Medicine, has received a five-year, $2.1 million grant from the National Institute of General Medical Sciences (NIGMS), part of the National Institutes of Health, for the study of repetitive DNA and RNA sequences and the mechanisms by which they cause cell dysfunction and diseases.

Weill Cornell Medicine has been awarded a five-year, $5 million grant from the United States Department of Health and Human Services through the Office of Population Affairs under the Teen Pregnancy Prevention Program to conduct a randomized trial testing whether a bilingual video game called “No Baby No (No Bebé No)” can increase the use of contraception among sexually active Black and Hispanic adolescents.

Pregnant individuals who had a previous COVID-19 infection and received a full course of COVID-19 vaccination and a booster have the strongest immune protection from the disease – and pass that protection along to their unborn babies.

The immune system of pregnant women with anxiety is biologically different from that of pregnant women without anxiety.

A protein commonly found at high levels in lung cancer cells controls a major immunosuppressive pathway that allows lung tumors to evade immune attack.

An artificial intelligence algorithm can determine non-invasively, with about 70 percent accuracy, if an in vitro fertilized embryo has a normal or abnormal number of chromosomes.

The long-term immune response to SARS-CoV-2 mRNA vaccination was similar in pregnant individuals compared with non-pregnant individuals of reproductive age.

Error-prone DNA replication and repair may lead to mutations and cancer in individuals who inherit a mutant copy of the BRCA1 gene, according to a new study by Weill Cornell Medicine investigators.
