Scientists have expressed genes from snapdragon in tomatoes to grow purple tomatoes high in health-protecting anthocyanins. Anthocyanins are naturally occurring pigments found at particularly high levels in berries such as blackberry, cranberry and chokeberry. Scientists are investigating ways to increase the levels of health-promoting compounds in more commonly eaten fruits and vegetables. "Most people do not eat 5 portions of fruits and vegetables a day, but they can get more benefit from...

Many people believe fossils are petrified bone or impressions of a shell in rock. But fossils actually are any type of evidence of the existence of a once-living organism - plant or animal. Accurately dating the age of the Earth is commonplace today. Take a few rocks, analyze them on fancy machines, and presto, out pops the Earth's age. But these techniques are not new. A century ago, B.B. Boltwood outlined the basics. Boltwood got his doctorate from Yale University in 1897. A decade...

By Chandler, Stephen Tanaka, Yoshikazu An important driving force for the floriculture industry is the development of novel plants and flowers. New varieties provide marketing opportunities for retailers and judicious selection can increase productivity for growers, as well as improving the quality of the final product in the consumer's hands. While plant exploration and conventional breeding programs have been very successful in achieving these goals, genetic modification offers additional...

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...

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...
