New findings overturn understanding of light-dependent environmental oxidants
Breathing oxygen… can be hazardous to your health?
Indeed, our bodies aren’t perfect. They make mistakes, among them producing toxic chemicals, called oxidants, in cells. We fight these oxidants naturally, and by eating foods rich in antioxidants such as blueberries and dark chocolate.
All forms of life that breathe oxygen—even ones that can’t be seen with the naked eye, such as bacteria—must fight oxidants to live. (more…)

The number of known places in our galaxy theoretically hospitable to life may be significantly greater than previously thought, according to new research.
Researchers with Planet Hunters are reporting the discovery of a Jupiter-sized planet in the so-called “habitable zone” of a star similar to Earth’s sun, as well as the identification of 15 new candidate planets also orbiting within their star’s habitable zone. (more…)
A person’s style of speech — not just the pitch of his or her voice — may help determine whether the listener perceives the speaker to be male or female, according to a University of Colorado Boulder researcher who studied transgender people transitioning from female to male.
The way people pronounce their “s” sounds and the amount of resonance they use when speaking contributes to the perception of gender, according to Lal Zimman, whose findings are based on research he completed while earning his doctoral degree from CU-Boulder’s linguistics department. (more…)
Experiencing rejection not only affects how we think and feel — over the long-term it can also influence our physical and mental health. New research suggests that when rejection comes in the form of discrimination, people respond with a pattern of thoughts, behaviors, and physiological responses that may contribute to overall health disparities.
“Psychological factors, like discrimination, have been suggested as part of the causal mechanisms that explain how discrimination gets ‘under the skin’ to affect health,” says psychological scientist and senior researcher Wendy Berry Mendes of the University of California, San Francisco. “We wanted to explore the behavioral consequences that follow experiences of discrimination to better understand these mechanisms.” (more…)
