Scientists discover a surprising paradox in how our cells age

Scientists have discovered that the body's cellular recycling system behaves very differently during aging than previously believed, with higher activity sometimes linked to worse physical health. A small study suggests that even gentle exercise could help restore more youthful cellular recycling patterns in older adults.

Only one workout helped older adults lose fat and keep muscle

A six-month study suggests that high-intensity interval training (HIIT) may offer older adults a powerful advantage: losing body fat while keeping their muscle. Unlike moderate-intensity workouts, which led to a small loss of lean muscle, HIIT preserved it while also improving body composition around the waist.

Brain cells meant to protect us may be fueling cognitive decline

Scientists have uncovered a surprising cause of age-related cognitive decline involving brain cells previously thought to be entirely beneficial. As these cells become dysfunctional, they can produce abnormal amounts of myelin, disrupting nerve fibers and potentially contributing to worsening memory and thinking skills.

Because this somehow still seems to be necessary.

Scientists may have overlooked a hidden Alzheimer's culprit for decades

For decades, scientists have focused on amyloid beta as a major culprit behind Alzheimer’s disease, spending billions of dollars developing treatments that have often delivered disappointing results. Now, researchers at UC Santa Cruz are drawing attention to a largely overlooked peptide called P3 that could also play a role in the disease. Previously believed to be harmless, P3 can form harmful-looking protein clumps even faster than amyloid beta and may also damage brain cells.
