Is it better to jump with a long foot or short foot?
The cases below only differ by whether the in-lever or out-lever is bigger. Which will jump higher?
Ignore contraction dynamics & imagine the body is constrained to go straight up.
Answer and discuss below 👇 #biomechanics
Thanks to all who made it to my talk at #SEB2023! For those who couldn't, here's a prerecorded version https://youtu.be/BIwkG6a5WEo
Watch to find out when it's better for a foot to be a foot vs a leg... And how #lizard toes are a bit like wheels 🦎🛞
What does this #3Dprinted device have to do with #Lizard feet? To find out, come to my #SEB2023 talk Fri at 9:30 in Tinto for the Open #Biomechanics session: "Plantigrade feet avoid work through serial linkages"
You might even get a copy to take home (while supplies last)! 🦎👣
Hoping to connect over here with #evolution #biodiversity and #biomechanics folks! Will aim to post and support others. Here is a cool surgeonfish (Ctenochaetus) we dissected recently.
For the record, I acknowledge that the wrist contacts the ground, so the forelimbs are unambiguously plantigrade. To my eyes, though, the hindlimbs are digitigrade.
Also, not everyone agrees in the literature; some authors explicitly say mice are digitigrade - e.g.
https://doi.org/10.3389/fbioe.2018.00061
Are #mice and #rats plantigrade or digitigrade?
I've seen a loooot of studies that code them as plantigrade (e.g.
https://doi.org/10.1073/pnas.1814329116)
... but their ankle is well above the ground (e.g. video from https://doi.org/10.3389/fnins.2016.00042)

Any recommendations for #dinosaur activities for a class of 4-5 year-olds? Visiting my daughter's classroom in a few weeks to talk about #dinosaurs, but coming up short on ideas! I have access to #3dprinting and laser cutter if that helps... #SciComm #education 🦖🦕

Can you see the bat sleeping in the snow?❄️
The Ussuri tube-nosed bat (𝘔𝘶𝘳𝘪𝘯𝘢 𝘶𝘴𝘴𝘶𝘳𝘪𝘦𝘯𝘴𝘪𝘴), found in Japan, Siberia, & Korea, is one of only two animals known to hibernate in snow- the other being polar bears.

Another #introduction post for all the new Twitter people (and just new people in general!). A little about me: I’m Sabrina - I’m a #writer (some #scicomm) and #author of #ScienceFiction (and #ClimateFiction and #dystopian) #books - my series Aestus was on the Amazon hard #scifi bestseller list recently. 😊 I also do #archery and #photography and enjoy #hiking - I would love to get into #astrophotography. I am learning #German and really enjoy good convos/coffee/tea. Sry for so many hashtags 😅
Just seen on Mastodon that the Sony/BMG royalty dispute means Rick Astley's "Never Gonna Give You up" is now blocked globally on YouTube. Playing just yields a "blocked in your region" message.
Absolute end of an internet era. 😔
8 wheels = 96 "legs" to bring to #SICB2023 Keep your eyes out for the passive dynamic walkers on Thursday 👀
