Xenobots, a type of programmable organism made from frog cells, can replicate by spontaneously sweeping up loose stem cells, researchers say. This could have implications for regenerative medicine.
A panel of U.S. health advisers on Tuesday narrowly backed the benefits of a closely watched COVID-19 pill from Merck, setting the stage for a likely authorization of the first drug that Americans could take at home to treat the virus.

NASA uses stuffed animals on flights because when the little guys start to float, it indicates that the spacecraft has entered space's zero gravity.
Scientists have evidence that SARS-CoV-2 is circulating in white-tailed deer in the U.S. They say the findings could essentially dash any hopes of eliminating the virus in the U.S. — and the world.
