Fact of the day: the Irish Gaelic word for jellyfish—smugairle róin—translates literally as 'seal snot'.

I hope the strait of Hormuz is closed for as long as Israel closed the Rafah border. Yes. This affects all of us, so does genocide, but that didnt seem to move enough people, so maybe inflation will

GM orange petunias were made in the late 80s, but were banned in USA and EU cos GM. They circulated illicitly among petunia-fanciers until they were found outside a Finnish railway station in 2017. Cue THE GREAT PETUNIA MASSACRE. They were all destroyed. You can now buy them legally. More:

The internet, on scientists: They're secretive gatekeepers, they hoard esoterica/the truth, they don't want anyone in their ivory tower little clubs

Actual scientists: LOOK, WE FOUND A 300 MILLION YEAR OLD FOSSILIZED CLOACCAL IMPRESSION AND THE VENT IS HORIZONTAL! PLZ READ MY 67-PAGE PAPER ABOUT IT

A look at the Neanderthal deep cave structures from Bruniquel Ten years after describing the site, new work details ancient access to the cave.

Early Neanderthals walked into this cave, went three football fields into the earth, created 15-foot-wide bubbles of rock, lit and tended small fires upon them. Then they left.

This unique find has implications for how we underestimate many past peoples.

Took this week's seminar speaker for a walk around campus and was able to point out a firecrest 😊

I just stood beneath a singing firecrest and I think I’ve gotten everything I needed from life. A bullfinch nest, a pine marten and a firecrest.

Two scientists look at a monitor attached to a large apparatus consisting of pipes, tanks, vessels and hoses. 

The first scientist says
"I don't get it. The reaction is running perfectly, but we can't account for 7% of the heat."

The other says
"Have you Asked the Professor?"

The first replies
"We're not supposed To disturb him when He's in his office."

 On the other side of the apparatus, one of the pipes goes through a wall into another room where it warms the water for a hot tub in which the professor relaxes.

My GP thinks it’s orange fever, and has prescribed some mermaid scales, a lion's sneeze, a unicorn horn and half a pound of cheese.

Saw one yesterday but it was too far away to be able to say that I recognised it visually. But today I did get close.

The quest is over.

New teaching neurosis drops.
Student: It's funny. When I listen to the lecture recording the microphone picks up you heart beating, and so I can hear when you get nervous.
<sees look on my face>
Oh don't worry, it's not very noticeable.
2nd Student: Oh yeah, I've totally noticed that too!

Blue tit inspecting the entrance to the nestbox next to my office window. A little smaller and bluer than ideal, but pleasing nonetheless.

A rocky outcrop in the centre of the scene, with boulders and pebbles scattered around. In the distance, some gently rolling hills, and endless sand. All under a butterscotch sky.

You live in a time when you can see on your phone high-res photos taken over the weekend by a nuclear-powered rover on Mars.

I have never been good at art. Does these look like little faces? Or the organelles that transformed out planet?

“There is compelling evidence demonstrating that in-round riding of golf carts reduces the physical demands of golf, with users expending less energy and covering shorter distances”.

A stag in the field outside my shed-office has got a long rope tangled round its antlers. It’s trying to rub it off on a tree. Poor thing.

Don't think there's much I can do unless it gets tangled but would be glad to be told otherwise.

“Erbivores”. Is that a continent-wide pronunciation?
