Inserting, removing or swapping individual atoms from the core of a molecule is a long-standing challenge in chemistry. This ...

Heterocycles, molecular rings found in many pharmaceuticals, have a reputation for stubbornly resisting modification. That is, in a heterocycle, heteroatoms of one type aren’t easily swapped for ...

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 ...

Scientists are still trying to understand the nuances of oxygen’s atomic behavior in water. A new study using an ultra-advanced laser successfully imaged an oxygen atom in water for the first time. To ...
