In a study of the molecular mechanisms by which plants protect themselves from oxidation damage should they absorb too much sunlight during photosynthesis, a team of researchers has discovered a molecular "dimmer switch" that helps control the flow of solar energy moving through the system of light harvesting proteins. This discovery holds important implications for the future design of artificial photosynthesis systems that could provide the world with a sustainable and secure source of...

NEW YORK (Reuters Health) - For people who don't smoke, the risk of developing diabetes is lower in those with higher levels of carotenoids in their blood, according to a new report. The effect is not seen in smokers, however. Carotenoids -- plant-derived antioxidants found in vegetables such as carrots, tomatoes and spinach -- may reduce the risk of diabetes by cutting oxidative stress, the authors of the study explain in the American Journal of Epidemiology. Likewise, high levels...

NEW YORK (Reuters Health) - The risk of developing diabetes for people who don't smoke nonsmokers -- but not smokers -- is lower in those with higher levels of carotenoids in their blood, according to a new report. Carotenoids -- plant-derived antioxidants found in vegetables such as carrots, tomatoes and spinach -- may reduce the risk of diabetes by cutting oxidative stress, the authors of the study explain in the American Journal of Epidemiology.

A new study in the July 18 issue of The Journal of Experimental Medicine shows that gold-colored bacteria are more harmful than their unpigmented relatives. A group of scientists led by Victor Nizet (UCSD, San Diego, CA) have discovered that the molecules that give certain bugs their color also help them resist attack by immune cells called neutrophils. Scientists and clinicians have known for many years that gold-colored strains of a bacterium called Staphylococcus aureus tend to be cause...


Word of the Day
out-herod
  • In the phrase to out-herod Herod, to be more violent than Herod (as represented in the old mystery plays); hence, to exceed in any excess of evil.
Herod refers to 'Herod the Great,' a Roman client king and 'a madman who murdered his own family and a great many rabbis.' According to the OED, the term is 'chiefly with allusion to Shakespeare's use' in Hamlet.
