Researchers found that growing brain organoids with mouse skin cells combined with four growth factor molecules produces the best results for cell therapy studies. Their guidelines could help standardize organoid development, which may lead to more accurate medical models.
Researchers simulated Earth’s collision with the ancient Mars-sized celestial body Theia, showing how it could have created the Moon 4.5 billion years ago. The simulation suggests the molten Earth would have absorbed most of Theia, leaving today’s relatively puny Moon in orbit.
Scientists identified asteroid 1998 OR2 as the nearest known source of shock-darkened meteorites, which are altered by impacts to look as if they’re made of different materials. Identifying the sources of these meteorites is important to efforts to deflect potentially hazardous asteroids.
NASA combined data from the James Webb and Hubble Space Telescopes to find where dust is collecting in galaxy pair VV 191. Tracing interstellar dust can show scientists where new stars are forming, and the finding was only possible by comparing the two telescopes’ different capabilities.
