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…

Caltech scientists developed a hybrid quantum memory that stores qubit states 30 times longer by converting them into sound waves. The method, using mechanical oscillators at gigahertz frequencies, reduces energy loss and shows scalability potential. Published in Nature Physics, the breakthrough marks a step toward practical, long-term storage for superconducting quan…
