The late-night screen habit that steals your sleep

Paperleap podcast ·

2025/08/12

A large international study of over 45,000 university students found that each extra hour of screen use in bed after lights out was linked to a 59% higher likelihood of insomnia symptoms and roughly 24 minutes less sleep per night, regardless of activity type. Surprisingly, students who used only social media before sleeping had better sleep outcomes than those engaging in other screen activities, suggesting total time on devices may matter more than the specific content consumed.Read the full

Antibody raincoat keeps muscle stem cells young

Paperleap podcast ·

2025/08/09

Researchers spotlight a precision “immuno-prevention” strategy for sarcopenia, showing that an antibody called 1H41C10 shields the muscle-repair molecule HGF from oxidative damage and restores its ability to activate stem cells in lab tests. The findings suggest that protecting this single growth factor, rather than broadly fighting free radicals, could one day translate into therapies that preserve muscle strength and function as we age.Read the full article
