When we thought Tesla’s Optimus project was settling into a routine of shirt-folding chores and tasks, Elon Musk threw us a curveball. A new video, shared by the Tesla CEO on X(formerly Twitter), showcases Optimus in its new Gen 2 avatar in a state we haven’t seen before, walking but decidedly undressed.

But unlike the polished presentations we’ve seen before, this time, Optimus is bare-bones, revealing its intricate inner workings in all their unpolished glory.

Astronomers have identified the most massive stellar black hole yet discovered in the Milky Way galaxy. This black hole was spotted in data from the European Space Agency’s Gaia mission because it imposes an odd ‘wobbling’ motion on the companion star orbiting it. Data from the European Southern Observatory’s Very Large Telescope (ESO’s VLT) and other ground-based observatories were used to verify the mass of the black hole, putting it at an impressive 33 times that of the sun.

Researchers at the University of Copenhagen’s Niels Bohr Institute have developed a new way to create quantum memory: A small drum can store data sent with light in its sonic vibrations, and then forward the data with new light sources when needed again. The results demonstrate that mechanical memory for quantum data could be the strategy that paves the way for an ultra-secure internet with incredible speeds.
