A number of people just signed up this week for Friday’s Elk–I’m guessing after seeing a link to it in my Reddit Ask-Me-Anything session on Tuesday. Welcome!

Just so you know, I use this email to keep interested folks up to date with my writing and talks. And, taking a page from science writer Ed Yong (who puts out a superb email newsletter), I’m going to start sharing the science-related things I’m consuming–articles, podcasts, etc.–that I consider particularly link-worthy. 

The Ultimate Parasite

Parasites are a thing for me. In Parasite Rex, I sang the praises of creatures like tapeworms. (One of my career highlights is lending my name to the tapeworm Acanthrobothrium zimmeri.) I’ve explored the exquisite stripped-down cunning of viruses in A Planet of Viruses. I have defended the reputation of parasites on Radiolab. But this week was the first time I reported on what is perhaps the ultimate parasite: deformed proteins called prions.

Prions replicate by forcing normal proteins to bend into their own disease-causing shape. On Tuesday, I wrote a story in the New York Times about a raging epidemic of prions that’s spread across much of the United States over the past fifty years.Aside from hunters, most people aren’t familiar with it. That’s because chronic wasting disease attacks only deer and elk. For now, there’s no clear evidence of people getting sick from eating prion-laced meat from these animals. But that’s no reason not to be concerned. One expert told me he sees only one promising way to slow down the outbreak: fire. (You could say, “Kill it with fire,” except that the prion was never really alive to begin with.)
 

The Gene That Makes Men Live Longer

To understand why we get old, scientists have been searching for genetic variations that are more common in long-lived people. It’s been a hard search, but in recent years scientists have had a few successes. I wrote earlier this month in the Times about a variant in the gene for the receptor for growth hormone that appears to extend people’s lives by a decade. For some reason, though, the effect only works on men. The study raises a lot more questions than it answers, so don’t expect an army of immortal men any time soon. Here’s my story.
 

The Genetics Revolution

The Aspen Ideas Festival asked me a few questions about how CRISPR and other new technologies are changing science and shaping our future. Here’s my response.
