Researchers discovered that leucine, a nutrient found in protein-rich foods, can supercharge mitochondria by protecting crucial energy-producing proteins inside cells. The breakthrough uncovers a powerful new link between diet and cellular energy — with possible implications for cancer and metabolic disease treatments.

A hearing would air questions about James O’Neill’s qualifications to lead the agency

MIT scientists have identified cysteine — an amino acid found in foods like meat, dairy, beans, and nuts — as a potent trigger for intestinal repair. In mice, a cysteine-rich diet activated immune cells that released healing signals, helping stem cells rebuild damaged intestinal tissue after radiation exposure. Researchers say the discovery could eventually lead to new dietary therapies for cancer patients suffering from treatment-related gut damage.

Jeffery Taubenberger’s departure from a leadership position caps year of upheaval at National Institute of Allergy and Infectious Diseases

A better understanding of battles between bacteria and viruses could inspire new medicines

Odd phenomenon first seen in plants could explain puzzling disease inheritance patterns

Women may be especially sensitive to the effects of common dementia risk factors, according to a new UC San Diego study of over 17,000 adults. Researchers say tailoring prevention strategies specifically for women could be key to reducing Alzheimer’s risk.

A newly identified enzyme called IDOL could become a major new target in the fight against Alzheimer’s disease. Researchers found that removing it from neurons sharply reduced amyloid plaques and improved key brain processes linked to resilience and communication between cells. The discovery may lead to future treatments that go beyond slowing Alzheimer’s — potentially helping protect the brain from further decline.

By restoring some functions to intact brains from deceased donors, the startup Bexorg hopes to create a better drug development test bed for neurodegenerative diseases

Researchers have developed a light-driven method for creating tiny, high-energy “housane” molecules that are valuable for drug development and materials science. These compact ring-shaped structures are difficult to produce because of the intense internal strain they contain. By using photocatalysis and carefully tuning the starting molecules, the team managed to guide the reaction into a clean and efficient pathway.
