Mathematical Equation Calculates Cost of Walking for First Time

Why do tall people burn less energy per kilogram when walking?

Any parent that takes their kid out for a walk knows that children tire more quickly than adults, but why is that? Do kids and small adults walk differently from taller people or do they tire faster for some other reason? Peter Weyand from Southern Methodist University, USA, is fascinated by the effect that body size has on physiological function.

‘Longevity Gene’ Helps Prevent Memory Decline and Dementia

Scientists at Albert Einstein College of Medicine of Yeshiva University have found that a “longevity gene” helps to slow age-related decline in brain function in older adults. Drugs that mimic the gene’s effect are now under development, the researchers note, and could help protect against Alzheimer’s disease.

New research may explain the ongoing loss of muscle in older people, whose arms and legs become thinner as they age

Have you ever noticed that people have thinner arms and legs as they get older? As we age it becomes harder to keep our muscles healthy. They get smaller, which decreases strength and increases the likelihood of falls and fractures. New research is showing how this happens — and what to do about it.

Coffee drinkers may have another reason to pour that extra cup. When aged mice bred to develop symptoms of Alzheimer’s disease were given caffeine — the equivalent of five cups of coffee a day — their memory impairment was reversed.

Coffee drinkers may have another reason to pour that extra cup. When aged mice bred to develop symptoms of Alzheimer’s disease were given caffeine – the equivalent of five cups of coffee a day – their memory impairment was reversed, report University of South Florida researchers at the Florida Alzheimer’s Disease Research Center.
