Hormone Hang-Ups
Parasitoid Wasps may turn spiders into zombies by hacking their internal code
Abril 26, 2019
Parasitoid wasps lay their eggs on a spider’s back. This team proposes that by injecting the spider host with the molting hormone, ecdysone, the wasp induces the spider to make a special web for the wasp’s pupa.

Is evolution predictable?
Butterflies take different paths to arrive at the same color pattern
Noviembre 14, 2019
Unrelated butterflies may have the same wing patterns. These patterns warn off predators and help suitors find the right mate. But if wing patterns in each species evolved the same way, knocking out an important gene should have the same effect in both. Carolina Concha and her team discovered that knocking out the WntA gene results in different effects in co-mimics, so the two species evolved the same pattern via different pathways.
