Hard believe it, but here’s the last Friday’s Elk of summer vacation…
 

I recently paid a visit to the lab of Jessica Whited, an assistant professor in the orthopedic surgery department at Brigham and Women’s Hospital in Boston. Whited doesn’t study people. Instead, she studies a spooky salamander called the axolotl. What makes the axolotl amazing is that it can regrow and entire leg in a matter of days. Whited is studying its powers of regeneration in the hopes of finding lessons that doctors can apply to people, coaxing our own bodies to fix themselves. I profile Whited in my latest “Science Happens!” video for Stat.

Front page news this week!
 

Twenty years ago, scientists were starting to study evolution in a new way: by picking apart the genes that govern the development of animals. Reporting on their work for Discover at the time, I was incredibly excited to watch the research unfold. Scientists could generate hypotheses about genetic changes that occurred millions of years ago, giving rise to new structures like limbs and wings. This new field of “evo-devo,” as it was sometimes called, helped inspire me to write my first book, At the Water’s Edge. Continue reading “Friday’s Elk, August 19, 2016” →

Greetings after a week of vacation!
 

Bet you never saw those words in that particular combination. Here’s the story:

Recently two scientists put together a new hypothesis about the evolution of the female orgasm. They argue that female mammals had orgasms, or at least precursors of them, 150 million years ago. And it started out with a function that was lost in our ancestors long ago. Continue reading “Friday’s Elk, August 12, 2016” →
