Shining light on the radical production of DNA building blocks

Despite its fundamental role in biology and extensive studies over half a century, many aspects of how DNA's building blocks are formed remain unclear. Now, an international team of scientists has revealed valuable details ...

Scientists discover how mitochondria import antioxidants

Many of the processes that keep us alive also put us at risk. The energy-producing chemical reactions in our cells, for example, also produce free radicals—unstable molecules that steal electrons from other molecules. When ...

Artificial anti-oxidant may be the next go-to supplement

Naturally-derived anti-oxidants have become the 'it' health ingredient to look for in food. But researchers from UBC Okanagan and the University of Bologna have discovered that TEMPO—a well-known artificial anti-oxidant—is ...

Researchers describe how free radicals contribute to aging

Aging in part is the result of oxidative damage to proteins caused by free radicals, a byproduct of interaction of our bodies and radiation such as sunlight. A new study by Yale scientists provides some clues into how this ...

Research reveals what turns free radicals on

(Phys.org) —UOW chemistry researchers have revealed what turns free radicals on...and off again in an article recently published in Nature Chemistry.

Silver nanoparticles may adversely affect environment
