🚨 Exciting new crab preprint! A Japanese team found that sideways walking only evolved once! Maybe carcinization itself is necessary but not sufficient to go sideways? When it's lost, the species that go forward have alternate anti predation behaviors. 🧪🦑🦀

Evolution of sideways locomotion in crabs
The evolutionary change in the mode of locomotion is often a major evolutionary event, triggering diversification. Sideways locomotion is a defining feature of true crabs (Brachyura) and may have cont...

This work reveals RNA stability as a "hidden layer" of gene regulation that: 1) Operates independently of transcription 2) Works locally in neuronal processes 3) Is disrupted in neurodevelopmental disorders 4) Expands our view of activity-dependent plasticity (10/11)

Focusing on what truly benefits kids, with their input, would save us all. I wish that, collectively, we desired a free future for children more than we desired the power to harm or control another adult. Every day I try to imagine that better world for all the children who should get to live there.

Sad to hear that David Baltimore died. I am one of hundreds of scientists that David generously mentored, supported, and inspired. His influence on each of us was deep and lasting, and his impact on the world immeasurable. Arguably David Baltimore is one of the greatest scientists of any generation.
