Elon Musk's claim his brain-machine interface startup Neuralink implanted a device in its first live human subject comes after the company navigated a rigorous approval process, with some bumps along the way.
Why it matters: If successful, Neuralink says its technology will allow users to operate devices like a phone using only brainpower, and could be used to treat neurological diseases. While the technology is unproven, starting human testing is a major step.
A "treasure trove" of images featuring 19 nearby spiral galaxies that the James Webb Space Telescope captured were released by NASA and partner agencies on Monday.
Why it matters: Scientists are studying the images and their analysis will "advance our understanding of star formation and the evolution of spiral galaxies," per a statement from the European Space Agency.
