My group at Science has been running a big campaign to engineer new channelrhodopsins.
Excited to share the first results from it today: a suite of highly sensitive new opsins.
We call them "WAChRs".
Everyday indoor office lighting is enough to activate them pretty strongly.

“whether C. cyclolites possess opsins…remains uncertain... However, C. cyclolites’ mode of locomotion, bell-shaped body plan, and ability to differentiate light bandwidths suggests the involvement of complex optical mechanisms and potentially more intricate neural systems akin to jellyfish.” Cool.
This disc coral rolls, slides, and pulses its dome-shaped body to “walk” in the direction of a light source.

Such an exciting diversity and quality of presentations related to the evolution of vision and opsins at #ESEB2025! I regret we did not organize an associated symposium on these topics. To make up for it, please pop by my poster today (035) and we can have a mini symposium right here!

We have 3 opsins in the cones. They are most sensitive to red, green, and blue wavelengths. (That’s why the light primary colors are RGB for humans.) The colors we perceive result from the brain’s processing of the signals sent by the opsins via the retina.

it's been months since learning what mice with fiber optic implants (for optogenetics studies) look like, and i still can't get over it. i would be so pissed off if i was a lab mouse who didn't get one of these.

There's actually a lot we know about that! Sticking to Red vs Green (L vs M), L and M cones themselves are the same cell type (not true of S), what makes them L or M is the opsin pigment they express.
