Scientists at the Lewis Katz School of Medicine at Temple University uncover how tau protein weakens the brain’s vascular defenses in Alzheimer’s disease

A harmful form of tau protein directly damages blood vessels in the brain, leading to inflammation and weakening the brain's protective shield. The discovery highlights the importance of focusing on early neurovascular changes mediated by tau to prevent or slow down damage to the blood-brain barrier.

Atomically dispersed catalysts are tough puzzles to solve, but worth the effort

Researchers are developing atomically dispersed catalysts to make industrial processes cleaner and more efficient. However, the field is plagued by common pitfalls, including inadequate testing and characterization. Experts like Jason Bates and E. Charles Sykes emphasize the need for repeatable, rigorous science.

New research explains why our waistlines expand in middle age

Researchers at City of Hope discovered a novel target for preventing age-related abdominal fat by identifying the cellular culprit behind midsection widening in middle age. The study found that aging triggers the arrival of new adult stem cells and enhances the body's massive production of new fat cells, especially around the belly.
