I was asked a couple weeks ago to contribute a piece to a special series of articles in Newsweek about the future of Wi-Fi. I must admit that a fair amount of the stuff that’s on the Wi-Fi horizon seems a little banal to me. It’s nice to know that I will be able to swallow a camera-pill that will wirelessly send pictures of my bowels to my doctor, but it hardly cries out paradigm shift. On the other hand, I’ve been deeply intrigued and a little disturbed by the possibility that the next digital device to go Wi-Fi is the human brain. Here’s my short essay on the subject.

STONY BROOK, NEW YORK—On a recent sunny Saturday, scientists from the United States, Canada, and Europe gathered at the State University of New York (SUNY), Stony Brook, to talk about their research. A geneticist from Harvard University spoke about preeclampsia, a potentially fatal condition during pregnancy. An ichthyologist described the loyalty—or lack thereof—that male fish show to the mothers of their offspring. Psychologists discussed economic decision-making. A psychiatrist reviewed some of the genes associated with clinical depression.

Jack Szostak, a scientist at Harvard Medical School, is trying to build a new kind of life. It will contain no DNA or proteins. Instead, it will based on RNA, a surprisingly mysterious molecule essential to our own cells. Szostak may reach his goal in a few years. But his creatures wouldn’t be entirely new. It’s likely that RNA-based life was the first life to exist on Earth, some 4 billion years ago, eventually giving rise to the DNA-based life we know. It just took a clever species like our own to recreate it.
On the east coast, we’re bracing for the howling emergence of a massive brood of 17-year cicadas in a couple weeks. Here’s a nice piece in the Washington Post about the evolution of this strange life history.
