DNA repair proteins monitored at double-strand break

...he site of a double-strand break allows the DNA to unravel and expose the area to repair proteins; the loss of functioning ATM and NBS1 blocks this important process. The team also showed that both NBS1 and ATM are needed to ensure that the repair factor, XRCC4, arrives at the double-strand break to help rep...

Danish researches solve virus puzzle

Deconstructing brain wiring, one neuron at a time

... and behavior. But these circuits are difficult to unravel because dozens of different neuronal types are entangled within a precisely connected network, and even neighboring neurons of the same type differ in connectivity and function. So, researchers have been trying to figure out the pattern of connec...

Researchers develop marker that identifies energy-producing centers in nerve cells

Gene study shows three distinct groups of chimpanzees

...itats, all threatened, instead of just one." To unravel the evolutionary history to chimpanzees, the research team collected DNA from 78 common chimpanzees and six bonobos, a separate species of chimpanzee, and examined 310 DNA markers from each. They found four "discontinuous populations," three of c...
