TUESDAY, Jan. 21, 2020 -- The chemicals in sunscreens help shield people from the sun's rays, but they are also absorbed into the body at levels that raise some safety questions, a new study confirms.
The study, by the U.S. Food and Drug Administration (FDA), is a follow-up to a 2019 investigation. Both reached the same conclusion: The active ingredients in popular sunscreens can be absorbed into the blood at levels that exceed the FDA threshold where they can be presumed safe.
THURSDAY, Oct. 31, 2019 -- Double-sided tape that quickly binds tissues shows promise in animal tests and may eventually offer an alternative to surgical sutures, researchers report.
"There are over 230 million major surgeries all around the world per year, and many of them require sutures to close the wound, which can actually cause stress on the tissues and can cause infections, pain and scars," explained study senior author Xuanhe Zhao. He is an associate professor of mechanical engineering and of civil and environmental engineering at Massachusetts Institute of Technology (MIT).
