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…

NASA’s Perseverance rover has discovered striking megaripples — giant Martian sand waves — at a site called Kerrlaguna in Jezero Crater. These formations, about a meter tall, are larger than Earth’s beach ripples but smaller than the biggest dunes. Scientists say they formed when Mars had a thicker atmosphere and stronger winds, and many now appear frozen in t…
