I hypothesize that they were knocked off by other cats.

The Oatmeal turns out to be wrong about them though. Yes, they have far more types of color receptors than us, but in tests of actual behavior they are much worse at discriminating colors.
See, we take out three types of cones and contrast them to get a whole gamut of colors. The same thing happens in other vertebrates and in insects like bees. That processing does take time though. In mantis shrimp vision is instead optimized for speed. The eyes have a special band in the middle to quickly scan things and in order to detect different colors at all, they need to have a different receptor for each one. Thatâs why they have so many.
They do see things that we donât, but they are not colors, they are polarizations. Insects, crustaceans, and cephalopods can generally see linear polarization. Mantis shrimp are so far unique in also seeing circular polarization, again with the special band. I donât know what all that tells them but some also do have circularly polarized markings, invisible to all animals except one another.

Just to be clear, they found a way to determine if a tumor is chemo-resistant so other modalities can be used. The headline reads as though the tumors are gaining resistance, as though they were bacteria or something. They are not.

That was a bit of a split second rollercoaster between reading FGD135âs and your comments; stomach drop, and then âwhew!â

Just saw my first case of postinfluenza encephalopathy ever. 13 yo kid, athlete, honor student, barely functional. No treatment but time. Scary as hell. (No flu shot either, but the uptake this year was absolutely miserable.)

Checks out. Sounds legit.

My immediate thought was; would it help with radiation shielding in outer space?

The four extra limbs might come in handy too.

The four extra limbs would come after the radiation exposure, I assume. Wouldnât that closing the barn door after the horse has left?

Honestly this feels like it might be more of a PR and fundraising pitch than a major development in mammoth de-extinction, but I would be curious to see mouse-sized mammoths if they figured out how to do thatâŠ

But there were also some intriguing findings, although the effect sizes were quite small. There was a slight association between how participants perceived the duck versus rabbit and optimism and emotional stability, for example. Whether a participant first saw the older or the younger woman did seem to correlate with age. And subjects who saw the seal first scored higher on intuition and spontaneity measures.
Schrödingerâs bun.
