Several processes in the human body are regulated by biochemical reactions involving hydrogen peroxide (H 2 O 2). Although it can act as a 'secondary messenger', relaying or amplifying certain signals ...

The common household chemical hydrogen peroxide, also made naturally by living cells, appears to be involved in regulation of circadian rhythms, according to a new study. If a circadian rhythm is like ...

Chemical engineers have developed a sensor that lets them see hydrogen peroxide inside cancer cells and determine whether they are responding to drugs that affect redox signaling. MIT chemical ...
