“Kangaroo care,” or skin-to-skin contact, may be neuroprotective and is associated with neonatal development in areas of the brain involved in emotional regulation in preterm infants, according to a new preliminary study from Weill Cornell Medicine, Burke Neurological Institute and Stanford Medicine investigators. Even short sessions correlated with noticeable effects on brain imaging scans, which is important because more than half...

A multi-institutional team led by Weill Cornell Medicine investigators has been awarded a five-year, $20.8 million grant from the National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health, for advanced preclinical development of a promising experimental HIV vaccine.

A successful vaccine to prevent new HIV infections would be a major public health breakthrough. About...

Patients taking an experimental oral GLP-1 drug lost significant weight and improved their heart and metabolic risk factors in a large, international, phase 3 clinical trial led by investigators at Weill Cornell Medicine, McMaster University, York University and other institutions.

The results from the ATTAIN-1 trial were published Sept. 17 in the New England Journal of Medicine. The trial included 3,127 non-diabetic patients with obesity or...

Weill Cornell Medicine has received a four-year, $3.4 million grant from the National Institute of Diabetes and Digestive and Kidney Diseases, part of the National Institutes of Health, for a study of the details and dynamics of the autoimmune process that causes type 1 diabetes. Dr. Shuibing Chen, the Kilts Family Professor of Surgery and director of the Center for Genomic Health at Weill Cornell Medicine, will lead the...

Increased risk for anxiety may begin before birth, shaped by infection or stressful events during pregnancy, according to a new preclinical study from researchers at Weill Cornell Medicine. While scientists have long known that maternal difficulty during pregnancy may raise a child’s risk for psychiatric illness, the biological pathways between these prenatal experiences and later mental health have been unclear.

The...

Although the material damage from 2012's Hurricane Sandy may have been repaired, the storm left a lasting impact on cardiovascular health, according to new findings from Weill Cornell Medicine and New York University researchers.

The study, published Sept. 3 in JAMA Network Open, found that older adults living in flood-hit areas in New Jersey faced a 5% higher risk of heart disease for up...

Nearly 20 years ago, a man named Timothy Ray Brown who was living with HIV and cancer, underwent two courses of stem cell transplantation to treat his acute myeloid leukemia. By using donor cells that lacked a key molecule needed for HIV to enter and infect immune cells, the procedures not only led to remission of his cancer, but also cured him of HIV.

When SARS-CoV-2, the coronavirus that causes COVID-19, began spreading worldwide in 2020, many research teams immediately set to work developing a vaccine against it. Building on decades of previous work on mRNA technology and on other viral vaccines, including HIV, they achieved their goal within the year. The most widely used mRNA vaccine design contains the genetic instructions for...

A multi-institutional team led by Weill Cornell Medicine has received a five-year, $14.9 million grant from the National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health, to find ways to remove latent HIV from the cells of individuals with HIV. The team aims to use a personalized medicine approach to transform the management of HIV into effective cures.

Over 40 million people worldwide are living with HIV, according to the World Health...

Neurons in the gut produce a molecule that plays a pivotal role in shaping the gut’s immune response during and after inflammation, according to a new study by Weill Cornell Medicine investigators. The findings suggest that targeting these neurons and the molecules they produce could open the door to new treatments for inflammatory bowel disease and other disorders driven by gut inflammation.

Hundreds of millions of neurons make up the enteric nervous system, the “second brain” of the...

Dr. Rainu Kaushal, a distinguished health services researcher, information scientist and physician leader, has been named senior associate dean of health data science, effective immediately.

In this new role, Dr. Kaushal will help Weill Cornell Medicine harness data science opportunities in service of better patient outcomes. She will work across academic departments to develop the institution’s strategic vision for data science,...

Dr. Daniel R. Alonso, dean emeritus of Weill Cornell Medicine-Qatar and professor emeritus of pathology and laboratory medicine at Weill Cornell Medicine, died July 31 in Norfolk, Va., at age 88. An esteemed physician, administrator and teacher, Dr. Alonso served both institutions with distinction for more than 40 years.

A native of Argentina, Dr. Alonso started medical school at age 17 enthusiastic about medicine but unsure about what specialty to practice, recalled his son,...

COVID-19 prevention methods such as masking and social distancing also suppressed the circulation of common respiratory diseases, leaving young children lacking immunity to pathogens they otherwise would have been exposed to, a new multi-center clinical research study reveals. The investigators say their findings help explain the large post-pandemic rebound in these diseases and enable more accurate predictions for the future.

By understanding differences in how people’s brains are wired, clinicians may be able to predict who would benefit from a self-guided anxiety care app, according to a new analysis from a clinical trial led by Weill Cornell Medicine and NewYork-Presbyterian investigators. The preliminary study suggested that young people with weaker connections between two brain areas involved in both attending to and regulating responses to anxiety were more likely to benefit from a self-guided anxiety care...

A new study reveals that some men who are diagnosed with “Grade Group one” (GG1) prostate cancer may actually be at higher risk than biopsy results suggest, according to research led by Weill Cornell Medicine, University Hospitals Cleveland and Case Western Reserve University. The researchers conclude that relying on biopsy grade alone can lead to underestimating disease risk and misclassifying individuals who may benefit from definitive treatment with either surgery or radiation. Biopsies...

Dr. Mohammad Arifuzzaman, an assistant professor of immunology in medicine, was named a 2025 AAI ASPIRE Award winner by the American Association of Immunologists. The award recognizes up to six outstanding early career investigators for research accomplishments and professional promise in the field of immunology.

Dr. Veronika Horn, a postdoctoral associate...

Weill Cornell Medicine researchers have discovered that PD-1—a molecule best known for putting the brakes on immune cells—also plays a critical role in helping T cells become long-term immune defenders in the skin. Early during infection, PD-1 acts like a steering wheel, guiding T cells to become protective resident memory T cells (TRM) that stay in place. These cells remember invading germs or cancer and quickly mount a response if that enemy reappears.

The preclinical...
