A Fingertip Patch Monitors Parkinson’s Drugs Through Sweat

Biotechnology, Medicine /

A battery-free sweat sensor could enable quicker, more personalized monitoring of levodopa levels in people with Parkinson’s disease. For people living with Parkinson’s disease, the benefits of a levodopa dose can sometimes wear off suddenly, causing movement difficulties to return before the next dose is due. To address this challenge, engineers and neuroscientists at the

MIT scientists created lab-grown artificial blood vessels using magnets

Biotechnology, Medicine /

Scientists hope to one day replace damaged body parts with lab-made alternatives, but recreating complex tissues and organs remains challenging. Blood vessel networks are particularly difficult to reproduce because tiny capillaries can be microscopic, with some measuring just 0.005 millimeters wide and allowing blood cells to pass through one at a time. MIT Creates More
