Liquid transforms into an energy-rich gel that stores power for months

A new liquid material developed by Northwestern University can harvest, store, and release energy in a single system, transforming into a black gel upon charging that stores power for months and reverting to liquid when exposed to air. Inspired by cellular cytoskeletons, it is the first material to store energy by physically rebuilding itself, with potential applications in energy storage, environmental remediation, and soft electronics.

How working memory could give rise to consciousness

The “doorway effect” occurs when entering a new room causes you to forget your intention because working memory, which holds limited information (about four “slots”), clears that information once it’s no longer needed. This phenomenon highlights the close link between working memory and consciousness, as forgetting in working memory corresponds to leaving conscious awareness.

A martian rock has lots of carbon on it, and it’s not clear why

NASA’s Perseverance rover detected complex macromolecular carbon on the surface of a rock at Bright Angel in Jezero Crater, the shallowest such detection on Mars. The carbon’s spectral signature resembles terrestrial kerogen, which is typically biological in origin, but researchers caution its source could be abiotic without sample return.
