[MIND] For generations, we’ve assumed memory to be a purely brain-based function, encoded in the wiring of the tangled neurons and electrical impulses in our brains that surge when we remember a face, a song, or a heart-warming story. But a remarkable study from New York University is forcing us to reconsider that assumption. The researchers found that human cells outside the brain - including kidney and connective-tissue cells - can display a primitive form of memory-like behavior . In this research, scientists exposed non-neural cells to bursts of chemical signals (imitating neurotransmitters). When the bursts were spaced apart, the cells activated a specific memory-related gene more strongly and for a longer duration than when signals came rapidly or continuously. That reaction lingered, as if the cells had formed a kind of molecular memory. This research challenges everything we thought we knew. ...
[HEALTH] Forget fancy fitness trackers - your floor might be the truest measure of your health! The Sitting-Rising Test (SRT) is a quick and easy test that measures your muscular strength, flexibility, balance, and “risk of death” in less than a minute. HOW TO DO THE SITTING-RISING TEST Start by standing barefoot on a flat surface. Lower yourself to the floor without using your hands, knees, or arms for support. Get up again, without using any support. The ideal score is 10 points, 5 for the sit and 5 for the rise. You lose 1 point each time you use a hand, knee, or lose your balance. Half-points are also subtracted for slight instabilities. SCORING 8–10 points: Great mobility and physical condition 6–7.5 points: Fair, could have better flexibility or balance 3–5.5 points: Below average, showing a lack of functional fitness 0–2.5 points: Bad, with higher risks of falls and even mortality in the elderly WHY IS THIS IMPORTANT? In 2012, a study published in the European Journa...
