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

TWENTY children have been 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...

For inferring the biological tree of life, simple is better

It has long been known that several metabolic traits including high cholesterol and hypertension cluster in individuals more frequently than by chance, but the underlying causes were unknown. This study, published early in Science Express on line, suggests that alter...

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 ...
