Scientists are scouring garbage sites around the world for bacteria, fungi and even insects that harbor enzymes that could be harnessed for breaking down various polymers. It’s early days, but if the efforts can be efficiently scaled-up, such biological recycling could put a dent in the plastic waste problem.
A new character has stepped onstage in the story of human aging: neural excitation.
The brain’s neural activity, long implicated in disorders ranging from dementia to epilepsy, plays a role in human aging and life span, according to research led by scientists in the Blavatnik Institute at Harvard Medical School.
