‘The results were impressive’: Drug to fight aging purges the body of damaged ‘zombie cells’

A drug to fight aging may finally be on the horizon after the first trials in humans showed “impressive” results. For many years, scientists have known that an accumulation of senescent cells in the body is linked to aging symptoms such as frailty and arthritis, as well as diseases such as Alzheimer’s and Parkinson’s.

Exercise-related hormone irisin found to target key bone cells

Scientists have discovered that irisin, a hormone released by muscles during exercise, directly acts on key regulatory cells that control the breakdown and formation of bone. The researchers say this insight raises the prospect of new treatments for bone-thinning disorders such as osteoporosis. Reporting in Cell, Bruce Spiegelman and colleagues at Dana-Farber Cancer Institute say they have for… Read More »
