Cyclopropanes are organic chemistry's smallest rings. Three carbon atoms are joined in a triangle, creating a compact and unusually strained structure. Despite—or partly because of—this unusual geometry, cyclopropanes are ...

Packaged food usually sits in plastic-lined bags designed to keep air, moisture and contaminants out. That same protection can also increase the chances of chemicals from the packaging seeping into the food. When a chemical ...
Copper has been knocked off the top of a stability ranking it had dominated for decades. Without altering the atoms directly bonded to the metal, a KAIST research team reversed the longstanding trend in which copper generally ...
