To predict the behaviour of a primate, would you rather base your guess on a closely related species or one with a similar brain shape? We looked at brains & behaviours of 70 species, you’ll be surprised!

🧵Thread on our new preprint with @r3rt0.bsky.social , doi.org/10.1101/2025...
Brain Surfaces of 70 primate species

Sea stars control their movement speed and adapt to different loads and orientations by dynamically adjusting how long their tube feet stick to surfaces, demonstrating sophisticated locomotion without a central brain. In PNAS: https://ow.ly/lYwr50Y4uUe

The world feels rough right now

So please enjoy this shrimp, filmed off Cozumel, Mexico. It may be a larval reef shrimp, but we don’t know what species or how long it lives or what it eats. The world is still full of wonder and beauty and mystery.

Happy Winter Solstice!

Beer can, pinhole camera photos of the Summer to Winter Solstice (2024) and the Winter to Summer Solstice (2025).

You never know quite what you're going to get with these photos, set the beer can pointing towards the sun at hopefully the correct angle and wait 6 months!
A pinhole camera photo taken from Summer to Winter Solstice. It's a bit blurry as the aperture was made with a tiny needle and no focus mechanism. There are yellow to green lines across the photo, that's the Sun moving across the sky over the course of a day. The top line is from the Summer Solstice, the bottom line from the Winter Solstice. Cloudy days don't have any lines or broken lines as the Sun was obscured by clouds. There are some trees on the left, right and in the background. A pinhole camera photo, a 6 month exposure from Summer to Winter solstice. There are trees on the right side and background. A house with two cars in the drive are visible almost in the center of the photo. The lines are made from the Sun moving across the sky with the bottom line being the Winter Solstice and the top line the Summer solstice. On cloudy days the lines are broken or not visible as the sun was obscured by clouds. The lines show some reflections from a tree trunk. The lines are mostly a white color with some hints of blue, green and yellow in places. Some of the colors could be from rain or snow staining the paper I was using. A solargram/pinhold camera photo taken from the Winter Solstice of 2024 (21 Dec) to Summer Solstice of 2025 (20 June). It's a 6 month long exposure taken with a beer can pinhole camera, it shows the sun's movement across the sky during that time period, each day the Sun scribes a line on the paper in the pinhole camera. The bottom line is Dec 21 2024 and the top line is 20 June 2025. This kind of photo makes the movement of the Sun during the day into visible trails on the paper in the camera. There is a long orange-yellow arc going across the paper showing the whole 6 months. There is a shadow of my tree on the image, the tree blossomed during the exposure. Shades of blue and pink are on the paper too. There is a black kind of semi circle at the top of the image, that's where the water was disintegrating the top part of the paper.

I wrote a little bit about the "missing heritability" question and several recent studies that have brought it to a close. A short 🧵
The missing heritability question is now (mostly) answered

Hi, I’m David Brückner @davidbrueckner.bsky.social.

I’ll take you through how cells in a tissue can use information distributed by biochemical gradients to make decisions, and how we can measure such positional information.

This year we have sold 31% of the advent calendars that we sold last year 😓

The art is so pretty and colorful 🥺
The facts are so good 🥺
Eels are so cool 🥺

Get an eel facts advent calendar at EelFacts.net
Sarah holds up an eel facts advent calendar in front of blooming flowers on her sidewalk. It says eel facts an advent calendar. It has 24 boxes with orange and yellow zigzags and yellow circles in the middle with numbers one through 24 in the middle of the boxes there are six eels depicted on this calendar, one green Moray, two splendid garden eels, one blue and yellow ribbon eel, and one American eel and one European.
