Scientists get first glimpse at how plants, most animals repair UV-damaged DNA

...ort time, there's a danger of the donated electron jumping back to the photolyase enzyme before the repair is done. Zhong's work has revealed how the water in the pocket performs a critical function at this point. When the photolyase enzyme becomes excited, it jostles the water molecules, and that motion w...

European Commission funds EBI to do new research on synergies between bioinformatics and medical informatics

... shows less pathogenic strains are also capable of jumping to humans, giving them the opportunity to swap genetic material with human strains, which could result in a more virulent virus. Researchers in Italy studied outbreaks that occurred among poultry between 1999 and 2003, to determine the risk of avia...

Taking a flying jump

...n video, she showed that flies escaped by means of jumping in a forward fashion and directly away from the object, in addition to using their wings. Her results suggest that signals in the brain transferred via the 'giant fibre pathway', initiate a "take-off" sequence, involving stretching of the legs and de...

'Jumping genes' contribute to the uniqueness of individual brains

... Apart from their activity in testis and ovaries, jumping L1 elements are not only unique to the adult brain but appear to happen also during early stages of the development of nerve cells. The Salk team found insertions only in neuronal precursor cells that had already made their initial commitment to beco...
