Scientists have developed swarms of tiny magnetic robots that work together like ants to achieve Herculean feats, including traversing and picking up objects many times their size. The findings suggest that these microrobot swarms -- operating under a rotating magnetic field -- could be used to take on difficult tasks in challenging environments that individual robots would struggle to handle, such as offering a minimally invasive treatment for clogged arteries and precisely guiding organisms.

Microgravity is known to alter the muscles, bones, the immune system and cogni tion, but little is known about its specific impact on the brain. To discover how brain cells respond to microgravity, scientists sent tiny clumps of stem-cell derived brain cells called 'organoids' to the International Space Station.
