OSU researchers have found that a specific detoxification compound, glutathione, helps resist the toxic stresses of everyday life – but its levels decline with age and this sets the stage for a wide range of age-related health problems. A new study also highlighted a compound – N-acetyl-cysteine, or NAC — that is already used in high doses in medical detoxification emergencies. But the researchers said that at much lower levels NAC might help maintain glutathione levels and prevent the routine metabolic declines associated with aging.

Decline of these detoxification pathways are causally linked to cardiovascular dis...

These microrobots are powered by H2O2 and magnetically controlled. They will inspire a new generation of ‘smart’ microrobots that have diverse capabilities such as detoxification, sensing and directed drug delivery, the nanoengineers of University of California, SD said.

The technique used to fabricate the microfish provides many improvements over other methods with locomotion mechanisms, eg microjet engines, microdrillers and microrockets...
