About The Study: In this cohort study, exposure to Migrant Protection Protocols was associated with higher rates of trauma during migration among asylum seekers. Such policies may be associated with adverse health outcomes for asylum seekers, with potential downstream implications for U.S. public health and security. The Migrant Protection Protocols were introduced in January 2019 and changed U.S. asylum procedures by requiring certain asylum seekers to remain in Mexico while awaiting immigration proceedings.

A new AI model designs peptides (short proteins) that are targeted by enzymes called proteases, which are overactive in cancer cells. Nanoparticles coated with these peptides can act as sensors that signal if cancer-linked proteases are present in the body.

A class of ultrasmall fluorescent core-shell silica nanoparticles developed at Cornell is showing an unexpected ability to rally the immune system against melanoma and dramatically improve the effectiveness of cancer immunotherapy, according to a new study led by Weill Cornell Medicine and Cornell Engineering researchers.

Resistance to antibiotics is increasing worldwide. This also applies to drugs that are central to the treatment of tuberculosis (TB), such as bedaquiline. An international panel of experts from 32 countries has therefore presented specific antimicrobial stewardship standards for TB care for the first time. The recommendations, published in the International Journal of Tuberculosis and Lung Disease, aim to anchor tuberculosis more firmly in antimicrobial stewardship structures, optimize resistance monitoring and diagnostics, and improve the quality of treatment in the long term.

In a world-first, a team of researchers at the National Institutes of Health (NIH) and Emory School of Medicine, Atlanta, has successfully performed a coronary artery bypass — a normally open-heart surgery — without cutting the chest wall. The team employed a novel intervention to prevent the blockage of a vital coronary artery, which is a very rare but often lethal complication following a heart-valve replacement. The results suggest that, in the future, a less traumatic alternative to open-heart surgery could become widely available for those at risk of coronary artery obstruction.

January 6, 2026 – The American Pediatric Society (APS) is pleased to announce that Vanderbilt University School of Medicine has been selected as the host institution for the newly reinstated APS Howland Visiting Professor Program. This program serves as an extension of the prestigious APS John Howland Award, the highest honor bestowed by APS in recognition of distinguished leadership and contributions to academic pediatrics.
