Manhattan, which airs on WGN America and streams on Hulu, follows physicists designing what will become the bomb dropped on Hiroshima, starting about two years before August 6, 1945. The project staff and their families are living in a laboratory campus built and hyper-secured by the U.S. military in the desert near Los Alamos, New Mexico, but in many respects they could be working at any research university today. Here’s my (spoiler-y) list of the parallels, which are sometimes dangerously on-the-nose:
Over at The Molecular Ecologist, I discuss a new paper that exemplifies how we’re going to be studying the genetics of adaptation in the age of high-throughput DNA sequencing—even if it doesn’t quite live up to that promise. It’s a study of adaptation in Atlantic salmon, whose lifestyle makes them uniquely suitable for a particuar sampling design:
Salmon hatch in freshwater rivers, and spend at least their first year in that environment before swimming downstream to the ocean, where they develop into reproductively mature adults. When they’re ready to mate, they migrate back from the ocean, up the river where they hatched to spawn at the site of their birth. Those major migrations and the transitions between freshwater and salt-water are likely to be major selective events for salmon, and they offer convenient times to catch and study salmon from roughly the same age-cohort: when they migrate downstream to the ocean, and when they return to their birth-river.
By taking genetic samples of juvenile salmon on their way out to sea, and then adults on swimming upstream to breed, you can test for genetic changes—adaptation—that has occurred over the course of the fishes’ life in the ocean. And that’s exactly what the authors of this paper did—go read the whole post to find out how it worked.
So Science, that lovable institutional behemoth of scientific publishing, has just produced a list of “top 50 science stars of Twitter” that manages to contain, by my count—I’ve triple-checked—four women. Eight percent.
I hereby propose this as a new, painfully minimum standard for gender parity: If I passed more women on a trip between the dance floor and the bar at the Saloon last weekend than are present in your speaker roster, reviewer panel, or unasked-for list of notables, you’re doing it wrong. In the interest of establishing this as a rigorous benchmark, I plan to immediately embark on a systematic survey of gay bar gender ratios, starting Friday night; interested collaborators should contact me through the usual channels.

Over at Nothing in Biology Makes Sense, I discuss a big new review article on all the ways understanding evolutionary biology will be critical for human health and development in the next hundred years:
The long list of authors, led by Scott P. Carroll and including Ford Denison, whose lab is just down the hall from my office at the University of Minnesota, explicitly connect evolutionary principles to global goals for sustainable development. These include the reduction of both “chronic lifestyle” diseases and infectious diseases, establishment of food and water security, clean energy, and maintenance of healthy ecosystems. Carroll and his coauthors divide the applications of evolution to these problems into cases where evolution is the problem, and those where evolution may offer the solution.
