Almost 200 years after the Carnot limit defined the maximum efficiency of heat engines, scientists have introduced a microscopic design that seems to break the rule. Called the “Gambling Carnot Engine,” it works by monitoring a single trapped particle and stepping in at just the right instant. This clever feedback process allows the engine to convert nearly all ab…

On Sept. 21, 2025, GOES-19’s CCOR-1 coronagraph recorded a natural lunar eclipse. The Moon’s trajectory appeared curved due to a satellite yaw-flip. Unlike L1-based coronagraphs, GOES-19’s orbit enabled this rare capture, helping scientists refine imaging systems and improve understanding of the Sun’s corona.

Researchers in China have unveiled RoboFalcon 2.0, a bird-inspired robot with flapping, sweeping, and folding wing motions. Unlike earlier versions, it can achieve self-takeoff and maintain flight at low speeds. Tested in wind tunnels and real-world trials, the design showed improved control and reduced strain on lift. While limitations remain, such as hovering abilit…
