Prostate tumors can rewire amino acid metabolism to override the normal brakes on cholesterol production, a process that may fuel hormone therapy resistance, according to a study by Weill Cornell Medicine investigators.

A single application to water containers can significantly reduce yellow fever mosquito (Aedes aegypti) populations—and thus the spread of dengue fever—for many months. Researchers from the Faculty of Medicine at the University of Freiburg demonstrated this in a study published in The Lancet Infectious Diseases.

It’s widely understood that the microbiome—especially microbes found in the mouth and the gut—can have a profound effect on health. In a study published in the journal Cell Host & Microbe on Aug. 20, researchers report that by analyzing the makeup of oral microbes, they may be able to detect signals associated with gastric (stomach) and colorectal cancer. These findings could lead to the development of new, less invasive screening tests for gastrointestinal cancers.

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease that, according to the CDC, currently affects around 35,000 Americans—with 5,000 more diagnosed each year. Risk climbs with age, and treatments only slow progression. With no cure and an aging population, scientists are urgently seeking insights that could change those devastating outcomes.
