Created by the sun, the protective bubble of the heliosphere shields our solar system from harmful radiation. A new mission has launched to map it like never before.

Traditionally, chemical reactions have been described as one-line "equations" in which substrates, say A and B, convert purposefully but rigidly into a desired product, say C. Naturally, it has been ...

Reactions that sever typically unreactive carbon-hydrogen bonds, known as C–H activations, are a well-studied staple of organic chemistry. So it’s a well-known fact that palladium-based catalysts tend ...

NASA’s Interstellar Mapping and Acceleration Probe (IMAP) lifted off aboard a SpaceX Falcon 9 rocket from the agency’s ...
