the immune system, researchers have found. The finding may help explain how a mother avoids rejecting a genetically foreign fetus and provides a new target for treatments to help the immune system ignore other desirables like a transplanted organ. "...

some neurons near the green, quietly-firing cells. When she did that, the green cells were able to compete successfully and formed longer, more complex arbors. Although this work specifically examined the brains of fish, Smith said the same rules lik...
