Aging muscles may be losing strength for a reason scientists missed

What the research found
A newly identified breakdown in communication between nerves and muscles could help explain why people lose strength as they age. Researchers were able to improve muscle strength in an animal model by targeting a key protein, raising hopes that some age-related weakness could eventually be treated.
Evidence level: Human study. A study in people, but an association isn't proof of cause.
