While our cells are performing some important, basic functions, they can generate compounds known as reactive oxygen species ...

For the first time, researchers have been able to show how a cell closes the door to free radicals—small oxygen molecules that are sometimes needed, but that can also damage our cells. The study is ...

Free radicals are highly unstable and reactive molecules that are literally stealing electrons from your healthy cells at this very moment, causing damage that accumulates over time and contributes to ...

Free radical chemistry centres on the study of species that possess one or more unpaired electrons – a feature that confers unique reactivity and diverse roles across chemical and biological systems.

Weill Cornell researchers uncovered how free radicals from astrocyte mitochondria can fuel dementia. Using new compounds that target these radicals at their source, they slowed brain inflammation and ...
