I've been watching some of the behind the scenes stop motion puppet development from the creators for this one for the last few years and I'm so pumped to go check it out!!! If you are an animation nerd I HIGHLY recommend the Laika Studios instagram account 🤌 theconversation.com/in-an-age-of...

theconversation.comIn an age of AI, Wildwood is a film that reminds us human creativity is irreplaceableThe latest stop-motion offering from Laika Studios was a 16-year-long labour of love.

Incredible work and fantastic video editing in this paper!

Here's what they don't tell you about woodpecker tongues: Some of them are barbed (pileated & downy 'peckers) to allow them to spear insects. The barbs are keratinized, so *hard*. Meaning woodpecker *threat displays* can involve poking an interloper with a barbed tongue. (📷: u/ElvisIsNotDjed)

A busy weekend of #3Dprinting!! Three long prints all between 19-31hrs. Unfortunately, the longest and probably coolest print failed from a suspected spool jam 😭 We were out for some of the weekend so I couldn't catch it in time. Time to remove all these supports! #Prusa #spiders #microCT

A wild story that sums up so much about this moment. Rare books bought up by a hyperscaler, driven across the country by truck, scanned and fed into the woodchipper by low wage workers so the rich can build and own systems that squeeze, surveil, and automate labor and control knowledge generation.

SCOOP: 404 Media placed a tracking device in a shipment of rare books to see which AI company was buying it. What did we find? It ended up at an Amazon facility where Amazon scans and destroys books. Yes. This is literally the logo outside the Amazon warehouse door. Read now:

1/8 Breathing seems automatic. But it's a finely tuned motor behavior that has to be controlled. In this preprint, I map the circuits that match a fly's respiration to the metabolic demands of flight and mitigate the risk of dehydration. 🧵🪰 www.biorxiv.org/content/10.6...

Here's the working prototype of my setup. It's a 3D-printed black block with a socket to hold a watch glass, and a 3D-printed diffuser that sits on top of the block. Recessing the glass greatly reduces stray light & glare. #NaturalHistoryCollections #Macrophotography #FocusStacking #DIYImagingStage

I've been working on a better setup for capturing focus-stacked images of immature insects in alcohol...and it's working well. 🙂 #NaturalHistoryCollections #Macrophotography #FocusStacking #Psephenidae #APennyForYourThoughts

After the Heiligenberg plenary lecture, there was another session of concurrent participant talks, for example a session on #evolution of sensory and motor systems chaired by @fiorella.bsky.social who also gave the talk "One and done or back for more: stinging strategies in bees and ants" 🐝🐜

Cool new behavior caught on video! This is a special type of octopus known as a #papernautilus (aka #argonaut) and her shell is a little less than 5cm. Watch as she extends and retracts her fleshy mantle - at the end, she rapidly retracts it all! #blackwater #blackwaterdiving

You know that annoying sound mosquitoes make when they buzz around your face? Florian Muijres reports that mosquito flight is the outlier among flies and they prioritize sound production at the cost of exceptionally high power requirements. #ICN2026

New methods preprint! doi.org/10.64898/202... Are you interested in #tracking 3D movements of animals into reconstructions of habitats using #photogrammetry? I'm specifically tracking #mantisshrimp but our approach could be adapted to other animals. Please reach out with questions or feedback 😊

doi.orgTracking animal routes in 3D space through reconstructed habitats from dynamic videosContextualizing the movements of animals into their three-dimensional (3D) habitat contexts is still a major challenge for fields relying on animal tracking methods. This promises to change as Structure-from-Motion photogrammetry tools and techniques revolutionize image processing into the truly 3D spatial realm, by enabling reconstructions of habitat models from overlapping photographs. Combined with tracking data, these techniques would help elucidate drivers behind animal movements that have been previously masked by two-dimensional approaches. Unfortunately, tracking methods are often still impractical for use with understudied or non-model animals, especially those living underwater. In this paper, we describe a method for tracking the translational movements of animals into a photogrammetric habitat model. Our approach spans three general parts: (1) filming the navigation paths of wild animals by following individuals with small cameras (GoPros) on extendable sticks whilst SCUBA diving, (2) reconstructing a 3D spatial habitat model from separate footage, and (3) manually plotting the 3D trajectories of animals into the habitat model. We used one popular commercial software for photogrammetric reconstruction, trajectory plotting, and measurement of trajectories, after which the plots can be exported in a variety of formats for further analyses. Straightforward and flexible methodologies such as this stand to encourage more fieldwork concerning animals that live in structurally complex habitats, or animals that are underrepresented in movement or navigation research. We expect that this approach can be adapted to study many aquatic or terrestrial animals in different habitats, and at various scales. ### Competing Interest Statement The authors have declared no competing interest.

This is such a beautiful scientific illustration.

Conceptually delighted and weirdly repelled by Julia Stack's vision of the "spinal homunculus" - the body scaled by numbers of spinal motor neurons devoted to each part. In its lap is the motor cortex equivalent, with large representations of the hands and face. academic.oup.com/brain/articl...
