NASA Spitzer Space Telescope has identified the fastest-spinning brown dwarf known. Brown dwarfs are generally more massive than planets but not massive enough to become stars. These cosmic in-betweeners are plentiful throughout the galaxy, but many mysteries about them remain. To measure the rotation rate of the brown dwarf, Spitzer looked for regular changes in its brightness that repeat with each rotation. Scientists then created a simulation of how the rotation speed would affect the brown d

Fastest 100 m by a quadrupedal robot - Guinness World Records The fastest 100 m by a quadrupedal robot is 16.33 seconds and was achieved by Whiterhino, developed by Center for X-Mechanics, Zhejiang University (China) in Hangzhou, Zhejiang, China on May 27, 2025. Whiterhino's exceptional performance stems from the robot forward design methodology developed by the XMECH lab. This achievement is the culmination of XMECH's long-term research in dynamic motion mechanics. The research was collaborativ
