We humans might not be able to regrow a leg, as can a cockroach or salamander, or regenerate a missing half, like a flatworm, but our organs can replenish themselves – thanks to stem cells. Two new reports about opposite ends of the respiratory system may pave the way for replacement breathing parts.

Gene therapy is experiencing a renaissance, with many of the recent successes in children. For some conditions, the younger the child, the better the genetic correction, because affected tissues degenerate with time. This is the case for adrenoleukodystrophy (ALD), the “Lorenzo’s Oil” disease that strips the insulation from brain neurons. One goal of  Read More
