Can soft machines remember past events using their body, without any processor? 💭 Out now in Device (Cell Press @cellpress.bsky.social), we harness bistable elastic shells to program and memorize locomotion behaviors upon interactions with the surroundings. 🎈🐙 🧪⚛️ www.doi.org/10.1016/j.de... (1/9)

christoph: "yes" is a wholesome answer, occasionally 😄
Zooming in, we saw that the worm bends its body so much that it can form a kink at the bend! Kinks are usually detrimental in structures. For example, Kinked straws are useless. But this nematode can reversibly kink its body and keep jumping!

Buckling normally happens when you compress something slender, but 'tug' on a piece of crumpled paper at two points and it also buckles. Read more about how this "localized-TUG folding" occurs in many systems at: www.pnas.org/doi/10.1073/pnas.2423439122
July 5 - 6 is World Firefly Day! Like a lot of insects fireflies are threatened by our actions. 🧪🐡Check out fireflyersinternational.net to find out how you can help gather data on these magical animals & help scientists track their populations. My #linocut print shows 3 fireflies (Photinus pyralis,

Physical synchronization of soft self-oscillating limbs for fast and autonomous locomotion
Animals achieve robust locomotion by offloading regulation from the brain to physical couplings within the body. In contrast, locomotion in artificial systems often depends on centralized processors. ...

Closing out my second talk at the RoboSoft workshops with this: take robot joy seriously! Examples include EMFcamp, Cat Royale, and sextech hack. Fantastic bunch of people doing cool things. Feels like my brain has had a good spring clean.

Why we study shrimp on treadmills: The case for curiosity-driven research
“If we cut or limit funding for curiosity-driven research, we risk shutting down the pipeline of future innovation,” writes Carole LaBonne of Northwestern.

Nature research paper: Adaptive locomotion of active solids https://go.nature.com/41KlOVd
Adaptive locomotion of active solids - Nature
The development of active solids based on centimetre-scale building blocks incorporating odd elasticity shows that they can spontaneously undergo limit cycles of shape changes, leading to adaptive locomotion such as rolling and crawling.

From a visit to the Renwick Gallery in DC a couple of weeks ago: a very cool art piece by Lauren Mabry showcasing coiling instabilities in viscous fluids. A beautiful intersection of art, fluid mechanics (and some rheology!). @sorheology.bsky.social @apsdsoft.bsky.social
