Something extraordinary is happening on Capitol Hill. This month, a once-in-a-generation public lands bill passed with overwhelming Republican support and was signed into law by President Trump. And ...

Stellar processes exemplify energy conservation, where energy released from nuclear fusion, though dispersing as light and neutrinos, remains fundamentally conserved by spreading over a larger volume.

When optical gain or loss are precisely controlled using nanophotonics, a new physical event called the non-Hermitian phenomenon can be observed, potentially the next-generation technology of optical ...

We are at a critical time and supporting climate journalism is more important than ever. Science News and our parent organization, the Society for Science, need your help to strengthen environmental ...

The first semester of an undergraduate physics course invariably spends a lot of time on two big ideas: The momentum principle and the work energy principle. Both deal with forces acting on an object, ...

Time crystals are a true anomaly as they violate the law of conservation, which states that energy cannot be created or destroyed. The crystals are incredibly rare, but now scientists at Yale ...

The Work Energy Principle is one of the big ideas in introductory physics courses. It's so big that the textbook presentation can get a little confusing - but it doesn't have to be that way. I haven't ...
