Organic molecule stores solar energy for years, then releases it as heat on demand

When the sun goes down, solar panels stop working. This is the fundamental hurdle of renewable energy: how to save the sun's power for a rainy day—or a cold night. Chemists at UC Santa Barbara have developed a solution ...

Redesigned electrolyte helps lithium-metal batteries safely reach full charge in 15 minutes

Lithium-metal batteries (LMBs) are rechargeable batteries that contain an anode (i.e., the electrode through which current flows and a loss of electrons occurs) made of lithium metal. Compared to conventional lithium-ion ...

'Dynamic plastic delocalization' can slow metal alloy cracking, engineers find

Metal alloys crack and fail through a mechanism called "fatigue" when repeatedly loaded and strained. While it is well known how to design alloys to withstand static loads and pressures, it is very difficult to design resistance ...

What is 'AI-induced psychosis'? Study explains how chatbots may sustain delusions

When generative AI systems produce false information, this is often framed as AI "hallucinating at us"—generating errors that we might mistakenly accept as true. But a new study argues we should pay attention to a more ...

From flattery to debate: Training AI to mirror human reasoning

Generative artificial intelligence systems often work in agreement, complimenting the user in its response. But human interactions aren't typically built on flattery. To help strengthen these conversations, researchers in ...
