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 ...

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 ...

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 ...

Polymetallic nodules, collected from the ocean floor, sit in simulated seawater in chemist Franz Geiger's laboratory at Northwestern University. An international team of researchers, including a ...
