Drinking tea improves brain health, study suggests

A recent study led by researchers from the National University of Singapore (NUS) revealed that regular tea drinkers have better organised brain regions — and this is associated with healthy cognitive function — compared to non-tea drinkers. The research team made this discovery after examining neuroimaging data of 36 older…

An ‘EpiPen’ for spinal cord injuries

An injection of nanoparticles can prevent the body’s immune system from overreacting to trauma, potentially preventing some spinal cord injuries from resulting in paralysis. The approach was demonstrated in mice at the University of Michigan, with the nanoparticles enhancing healing by reprogramming the aggressive immune cells — call it an…

Astrocytes protect neurons from toxic buildup

Astrocytes are overtaxed neurons’ pit crew. The brain cells collect damaged lipids secreted by hyperactive neurons, then recycle those toxic molecules into energy, researchers at the Howard Hughes Medical Institute’s Janelia Research Campus report May 23, 2019, in the journal Cell. It’s a mechanism to protect neurons from the damaging…
