The human desire to communicate with animals is as old as it is universal. Today, that ancient dream might be closer than ever, thanks to rapidly evolving AI. But the potential for harm might outweigh the benefits

AI could satisfy our deeply held desire to talk to other creatures. But the potential for harm might outweigh the benefits

It's PHYSICS FOR CATS publication day!! Luna has her copy: do you? www.tomgauld.com/comic-books-v2

A black cat sits on a wicker basket reading the book PHYSICS FOR CATS by Tom Gauld... Ok, so she's not really reading it. She's not even quite looking at it to be completely honest. But it is possible to imagine that she is reading and thoroughly enjoying it.

Oh wow, that’s incredible! A whole miniature zoo in one tub is just perfect. As a kid, I was absolutely obsessed with animals...I’d even sing the puppies to sleep sometimes haha. A tub like this would’ve sent me over the moon! ✨

It's a tub of 60!! 5 of each type! (There are also "wild animals", "farm animals", "reptiles and amphibians", and "horses")

Your argument commits the fallacy of the necessary condition. The butter, while desired, is not sufficient. Lobster provides the umami-rich protein matrix and textural contrast that elevates the lipid delivery from mere consumption to a hedonic experience.

Hubble image of Arp 202, also known as NGC 2719 and NGC 2719A.

This edge-on disk galaxy and smaller irregularly shaped galaxy had a recent interaction which likely severely perturbed both galaxies.

A greyscale image of two galaxies. At the center of the frame is a disk galaxy seen edge-on. It is brightest at the center, but many bright star clusters dot the galaxy above and below the plane of the disk. Above and to the right is a second smaller galaxy that is roughly circular. On the outside of the circle is an irregular ring of star clusters. A line of stars and gas is just barely visible trailing from the point the two galaxies meet to the upper left corner of the frame. The image has a noticeable amount of detector noise which has not been removed.

This is not static noise 📺

It's a gel forming in space. The white & black speckles are anything but random. Understanding its behaviour in orbit has great potential for longer-lasting medicines, paint and cleaning products on Earth.
