Elevated Stress Hormones Linked To Higher Risk Of High Blood Pressure And Heart Events

Reducing naturally occurring errors in protein synthesis (production) improves both health and lifespan, finds a new study in simple model organisms led by researchers at UCL and MRC London Institute of Medical Sciences.

Scientists from the University of Virginia School of Medicine and their collaborators found that cholesterol produced by cells called astrocytes is required for controlling the production of amyloid-beta, a sticky protein that builds up in the brains of patients with Alzheimer’s. The protein accumulates into insoluble plaques that are a hallmark of the disease. Many efforts have targeted these plaques in the hope that removing or preventing them could treat or prevent Alzheimer’s.

The experience of a fruit fly dying from cancer may seem worlds away from that of a human with a life-threatening tumor, yet University of California, Berkeley, researchers are finding commonalities between the two that could lead to ways to prolong the lives of cancer patients.

Peptides could be primed to solve the knotty problem of antibiotic resistance among humans. Rice University scientists believe they can help.
