Neurosurgeons identify growth of new adult brain cells, possible treatment for epilepsy
SAN FRANCISCO It had long been
thought that once the human brain is fully matured, no new brain cells develop. Now a team of researchers and scientists has found evidence of cell generation in the brains of adults with epilepsy and say it could lead to ground-breaking treatment f...

Babies born after surgery on eggs

born after doctors performed a kind of transplant surgery on the eggs of their mothers, for whom normal IVF had failed. But other experts are concerned about the long-term safety of the technique. The technique, developed by Chii-Ruey Tzeng's team at...

Molecule that helps DNA replicate may make good target for cancer therapy
...The proteins that bring about DNA replication have been
highly conserved during evolution; that is, the proteins are virtually identical whether the organism is yeast, an invertebrate or a human. Therefore, whatever is learned from yeast--which are much easier to work with than are human cells--is likely ...
