Scientists have discovered a unique beaked, plant-eating dinosaur in China. The finding, they say, demonstrates that theropod, or bird-footed, dinosaurs were more ecologically diverse in the Jurassic period than previously thought, and offers important evidence about how the three-fingered hand of birds evolved from the hand of dinosaurs.

Human tissues normally discarded after surgical procedures could be a rich additional source of stem cells for regenerative medicine. New research shows for the first time that human fallopian tubes are abundant in mesenchymal stem cells which have the potential of becoming a variety of cell types.

Sewage treatment plants fail to remove artificial sweeteners completely from waste water. What’s more, these pollutants contaminate waters downstream and may still be present in our drinking water. Researchers were able to demonstrate the presence of several artificial sweeteners in waste water.
Stressful life events are strongly associated with a person’s risk for major depression, but a certain gene variation long thought to increase risk in conjunction with stressful life events actually may have no effect.

New muscular dystrophy (MD) research is moving doctors and scientists closer to disease diagnosis in advance of patient symptoms. Since it is now clear that early treatment significantly improves life expectancy and quality of life for muscular dystrophy children, this new discovery regarding MD’s prenatal origin has the potential to result in earlier diagnosis, and [...]

Researchers have created bright, stable and bio-friendly nanocrystals that act as individual investigators of activity within a cell. These ideal light emitting probes represent a significant step in scrutinizing the behaviors of proteins and other components in complex systems such as a living cell.
