Another atom-swapping reaction has entered the ring. Yoonsu Park and his team at the Korea Advanced Institute of Science and Technology (KAIST) have devised a light-driven reaction that replaces an ...

Researchers discover that embedding iridium atoms inside catalyst crystals instead of on the surface dramatically improves ...

One broken piece of quartz in a physics lab could shed light on the history of life on Earth and the search for other habitable worlds. Today, most life as we know it depends on oxygen. Specifically, ...

After scientists created oxygen-28 in the lab, it almost immediately degraded, baffling physicists around the world. When you purchase through links on our site, we may earn an affiliate commission.

TALIF works by using a precisely tuned laser to excite the atoms being measured. Instead of absorbing a single photon, each atom absorbs two photons at the same time, and the combined energy of these ...

There is more than one way to describe a water molecule, especially when communicating with a machine learning (ML) model, says chemist Robert DiStasio. You can feed the algorithm the molecule's ...

Today, our sister planet Venus resembles an environment as close to hell as one can imagine. Surface temperatures on the amber world soar to 450 degrees Celsius (842 degrees Fahrenheit), while about ...
