Virtual reality appears to dramatically change how the brain physically registers pain

The work, which used a specialized type of magnetic resonance imaging to track pain-related brain activity, showed drops of as much as 97 percent in such activity in some brain centers. The study marks the first time that scientists have documented a link between virtual reality and pain reduction in terms of an actual physiological response.

Oxidants are responsible for sex in algae

Colonies of the multicellular green alga Volvox carteri exposed to temperatures of 111 degrees Fahrenheit (42.5 degrees Celsius) had twice the amount of free radicals, oxidants that can damage biological structures, as unheated colonies. High levels of oxidants within their cells activated the algae's sex-inducer gene, the researchers report.
