A ring of beads connected to tentacles A modeling study shows how chemical reactions can stimulate motion in simple systems, like the structure here—made of enzyme coated beads connected to ...
The reaction generates amino acids and nucleic acids, the building blocks of proteins and DNA. Four billion years ago, the Earth looked very different than it does today, devoid of life and covered by ...
Color-changing breath, chemical goo, elephant toothpaste. Color-changing breath, chemical goo and elephant toothpaste? Explore chemical reactions and discover how hydrogen molecules break and fuse to ...
Many attempts have been made to harness the power of new artificial intelligence and large language models (LLMs) to try to predict the outcomes of new chemical reactions. These have had limited ...
When you get right down to the atomic scale, things happen much faster than we’re used to. That makes it hard to actually see what happens during chemical reactions, so researchers at Harvard have ...
