Unicellular microRNA discovery
In the May 15th issue of Genes & Development, an international collaboration of researchers, led by Dr. Yijun Qi (National Institute of Biological Sciences, China), report on their discovery of microRNAs in the unicellular green alga, Chlamydomonas reinhardtii. This is the first finding of microRNAs in a unicellular organism. view more (2007-04-30)

Northwestern chemists develop new method for synthesizing anti-cancer flavonoids
Flavonoids. You've heard of them — the good-for-your-health compounds found in plants that we enjoy in red wine, dark chocolate, green tea and citrus fruits. Mother Nature is an ace at making them, producing different ones by the thousands, but no chemist has figured out a good way to synthesize a special class of these chemicals in the... view more...

Making mice with enhanced color vision
Researchers at the Johns Hopkins School of Medicine and their colleagues have found that mice simply expressing a human light receptor in addition to their own can acquire new color vision, a sign that the brain can adapt far more rapidly to new sensory information than anticipated. view more (2007-03-23)
Using brain scans, researchers find evidence for a two-stage model of human perceptual learning
Using advanced brain imaging techniques, researchers at Georgetown University Medical Center have watched how humans use both lower and higher brain processes to learn novel tasks, an advance they say may help speed up the teaching of new skills as well as offer strategies to retrain people with perceptual deficits due to autism. view more (2007-03-15)
