Welcome back and a big welcome to Axios' new science writer, Erin Ross. She'll be contributing to the newsletter, our stream and whatever else we cook up. As always, I look forward to your feedback and comments at alison@axios.com.

In this issue, read about this week's top science stories, a big idea from the world of computer science, and, of course, something wondrous.

Invite: I'll be in LA next week to moderate an Axios event about the human brain on Wednesday morning. It's one of the most exciting areas of science — with the potential to improve lives and answer deep questions about what it means to be human. More information and RSVP here.
