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 ...

Under physiological conditions, most double-stranded nucleic acids adopt right-handed helical conformations such as B-DNA or A-RNA. However, under specific cellular stresses, nucleic acids can ...

Oxidative stress is a direct consequence of an excess in the body of so-called free radicals—reactive, unstable molecules that contain oxygen. Free radicals are normal metabolic by-products and also ...

When you think of stress, you might turn to the family drama that kept you from sleeping at night or an overwhelming, heart-racing panic about an anxiety-inducing work project. However, there could be ...

Upon resonant excitation, plasmonic nanoparticles (NPs) interact strongly with light and induce localized surface plasmon resonance (LSPR) resulting from the collective oscillations of free electrons.

A new study suggests melatonin supplements may help night shift workers boost their body's DNA repair processes, potentially offsetting some of the damage linked to working overnight. The findings are ...

Sep. 1—(Family Features) In a healthy person, the body is like a well-oiled machine. However, sometimes things go wrong, and when that happens, finding the source of damage, illness or disease often ...
