Clearing Out Aging Cells Made Stem Cell Repair Work Far Better in Mice
Based on: Synergistic senolytic-regenerative therapy significantly extends healthspan and lifespan.
Old, worn-out cells (called senescent cells) seem to block the body's natural repair work. In mice with liver damage and forced aging, combining a treatment that clears these cells with stem cell therapy worked far better than either alone. The combo reversed signs of aging and restored repair signals. This is early animal research, not tested in people.

How a Cellular Calcium Glitch Speeds Up Aging in Mice
When cells lose control of their calcium balance, it sets off a chain reaction that triggers DNA damage and inflammation tied to aging. In mice, an old antidepressant called mianserin calmed this calcium chaos. It improved several signs of aging and lengthened their lives. This points to calcium control as a possible target for slowing aging.
Weak Grip Strength Linked to Higher Risk of Pneumonia and Sepsis
In over 400,000 UK adults, weaker handgrip strength was tied to higher rates of pneumonia, UTIs, skin infections, and sepsis. Each 5-kg drop in grip raised infection risk by about 5-10%. The link was strongest in underweight people, and inflammation-related proteins like GDF15 partly explained it.
Fitness Apps and Wearables May Boost Steps in Older Adults
Looking at 26 trials with over 4,000 older adults, digital tools like wearables and apps helped people walk about 800 more steps per day and get 46 more minutes of moderate exercise per week. But they didn't significantly cut sitting time or boost light activity. Standalone wearables and tools paired with human coaching worked best.
