Imagine tiny cages made of molecules, called bis-porphyrin nanocages. These cages have metals like iron, cobalt, or zinc at their core. Scientists used these cages to see how their tiny pores and interactions with carbon nanomaterials affect their ability to turn CO2 into CO. These cages can stick t
Cobalt is a key player in a new method that turns CO2 into useful stuff. This isn't just any method. It uses sunlight to power the reaction. The process involves special materials called metal-covalent organic frameworks (MCOFs). These MCOFs have tiny, super-efficient parts called catalytic active s
Imagine surviving a storm but still feeling its effects years later. That's what many people are experiencing with long COVID.

In France, patients with advanced or metastatic non-small cell lung cancer (LAM NSCLC) have been given nivolumab as a second-line or later treatment.
