Wearable tech requires both strength and flexibility. A new nanowire design -- a boron nitride nanotube (BNNT) filled with tellurium atomic chains -- holds promise for electronics triggered by light and pressure. Physicists have now created and tested the new nanowire alongside carbon nanotubes.

Some species of mammals can delay the implantation of their embryos until conditions are better for bearing and rearing offspring. This enigmatic reproductive strategy can help improve the odds of survival. Researchers have found some of the biological mechanisms behind this suspension of embryonic development. Similar reversible dormant states are also found in some cancer tumors.

The first crewed SpaceX flight could happen around May 7th
Last month, Elon Musk said he expected the SpaceX Crew Dragon to launch, with astronauts onboard, sometime between April and June. Now, Ars Technica's Eric Berger reports that first crewed flight could take off on May 7th. Though, due to "a number of variables not hardware related" the launch could happen in late April or later in May. We don't know yet how long the flight will...
Gulf coast mollusks rode out past periods of climate change
About 55 million years ago, a rapidly warming climate decimated marine communities around the world. But according to new research, it was a different story for snails, clams and other mollusks living in the shallow waters along what is now the Gulf Coast of the United States. They were able to survive.
