Zika virus, like all other viruses, is mutating

Not long after the appearance of an outbreak of viral disease, first scientists, and then newswriters, blame it all on mutation of the virus. It happened during the Ebolavirus outbreak in West Africa, and now it’s happening with Zika virus.

Early-life bacterial colonizers may influence later development of asthma

This past weekend, I went to visit a friend and meet his twin toddler boys for the first time. Though both boys eagerly ran around the playground we visited, one was just slightly less active. “He has asthma,” his dad explained to me, “but his brother doesn’t.” Why would two boys with the same e...
