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 ...

Sleep serves as the brain's nightly clean-up crew, flushing out harmful oxygen-derived free radicals that accumulate during ...

Is there a way to chemically manipulate small, confined areas on cellular surfaces? Scientists have developed a microfluidic probe to send a flow of free radicals on live cells and track the outcome ...

IN recent months the importance of the reactivity of the free radicals in polymerization systems has been stressed, in particular the ability of a free radical both to initiate and terminate reaction ...
