Chile’s complementary set of policies targeting food products high in fat, salt and sugar plausibly reduces the risk of school age children being overweight or having obesity, finds a study published in The Lancet.

As the Andes hantavirus draws international attention, a breakthrough from The University of Texas Medical Branch offers new hope. Single-dose mRNA vaccines are showing remarkable protection in preclinical studies.

A new study led by UCLA Health physician-scientists suggests that subtle changes in heart structure and function may signal an increased risk for developing certain cancers years later.

Blood lead levels in young children in the United States declined in the last decade, but state data reveal that children of color and children from low-wealth families are still exposed to higher levels of lead, according to a new study in the American Journal of Public Health. No level of lead in children’s blood is safe.

Honoring the legacy of Valentin Fuster, MD, PhD, MACC, president of Mount Sinai Fuster Heart Hospital in New York, forty-seven clinicians were selected to participate in the American College of Cardiology’s inaugural Fuster Prevention Forum in Washington on June 12 – 13.  The in-person, two-day educational course focuses on early cardiovascular disease prevention and equips clinicians with the tools they need to enact change and foster a culture of prevention in their communities.

The Society of Nuclear Medicine and Molecular Imaging (SNMMI) is pleased to announce the recipients of five Drs. Jane & Abass Alavi Mars Shot Research Awards from SNMMI’s 2026 Mars Shot Fund. With a focus on advancing imaging research in infection and inflammation, the awards will support studies on inflammatory bowel disease (IBD), artery inflammation, diabetic bone infections, prosthetic joint infections, and rheumatoid arthritis.

The Gerontological Society of America (GSA) has received renewed grant support to welcome a 17th class of reporters for the Journalists in Aging Fellows Program. The current funders include Silver Century Foundation, The John A. Hartford Foundation, The Commonwealth Fund, National Institute for Health Care Management Foundation (NIHCM), and Health Foundation for Western & Central New York.

A new Yale-led study provides one of the most detailed and comprehensive analyses to date of genetic variation in human populations in Oceania, filling a major gap in representation in genomics research. 

Despite harboring remarkable diversity, populations in this vast region in the South Pacific historically have been overlooked in global human genetic studies, which have often focused largely on peoples of European descent, researchers say. 

“The drastic underrepresentation of Oceanians limits our understanding of human evolution and could exacerbate health inequalities as genomic research is used to develop novel medical treatments” said the lead author Serena Tucci, assistant professor of anthropology in Yale’s Faculty of Arts and Sciences and the principal investigator of the Yale Human Evolutionary Genomics Laboratory. “To fill that gap, my research team embarked on a large-scale project to expand what is known about human genetic variation, including genetic variants inherited from extinct hominins.”

The study, published on June 11 in the journal Science, shows how the genes that ancient humans acquired after mating with extinct hominins continue to shape the biology, health, and survival of our species today.
