In advanced chemistry labs and classrooms around the world, one rule has quietly endured for nearly a century. Introduced in ...

Abstract: In this article, we propose an amplitude-modulated spin-decoupled anisotropic metasurface and its application to a dual-circularly polarized (dual-CP) transmitarray (TA) with suppressed ...

The key idea behind our framework is that life produces molecules with purpose, while nonliving chemistry does not. Cells ...

From Viking to Perseverance, scientists have spent decades chasing chemical hints that could point to life beyond Earth.

A way to electrically modify the chirality of organic–inorganic hybrid materials, in which chiral molecules adsorb onto ...

When NASA scientists opened the sample return canister from the OSIRIS-REx asteroid sample mission in late 2023, they found something astonishing. Dust and rock collected from the asteroid Bennu ...

Many carbon-rich meteorites contain ingredients commonly found in life, but no evidence of life itself. James St. John, CC BY When NASA scientists opened the sample return canister from the OSIRIS-REx ...
