The fallen tree here is, I am almost certain, a red oak I watched fall on a windy afternoon between 1994 and '98 in Wingra Woods, UW Madison Arboretum. I returned to it last week to get a sense of what 25 years of decomposition looks like for a red oak in an upland oak forest, north-facing slope, south-central Wisconsin.
Lake Wingra in the background, with white and red oaks and planted sugar maples.
@johnrhutchinson and his team used this exact mount from Staatliches Museum für Naturkunde Stuttgart for the 3D reconstruction of Batrachotomus. Our study also compared our simulations to fossil trackways of Chirotheriids, and was the first (that we know of) to identify gait transitions in an ancient pseudosuchian. It was a lot of fun, and I wish we still had "Rauisuchians" like Batrachotomus around today!
This 3D printed bearing has no right to be this good. This is how it is straight off the printer (with just a little work to free the rollers), no lubricant https://www.thingiverse.com/thing:2746804 #3Dprinting
#throwbackthursday to this #coolbugs I found in Bamfield BC 10 years ago. Harpaphe haydeniana, the "almond-scented millipede" (Almond scented because of the cyanide). I think they're pretty common but for an Alberta boy it was startling to see. Also #Mosstodon
When you spend hours trying to adjust the tolerances to fit a 6 mm Allen key only to realize that it's a 1/4" 😭 #3Dprinting #MetricPlease
Faculty at more prestigious universities publish more bc they have funded Ph. D. students and postdocs to do the work.
In fields where advisors aren't put on Ph. D./postdoc research pubs, there is no relationship between university prestige and faculty productivity.
Mid-career faculty, matched, who move to institutions with more funded Ph. D./postdocs publish more.
Counting pubs is a poor method of judging a researchers quality.
Hi! I am a CS PhD student at the University of Illinois, Urbana-Champaign. I am broadly interested in learning based #robotics to solve problems in #agriculture.
Currently I am working on vision-based navigation of under-canopy agricultural robots (https://ansivakumar.github.io/learned-visual-navigation/). These small robots could enable various precision agriculture applications like autonomous cover crop planting, mechanical weeding etc in an affordable way.

And if you’ve never seen Paddlefish eat, here you go:
^Paddlefish use that long snout (laced with electroreceptors) to detect plankton, then filter them out of water with their gaping mouths & sieve-like gill rakers! https://twitter.com/stuart_orr/status/1597342422572630016
So, robots in movies are always depicted as being nimble on their feet and dextrous -- like the new trailer for M3GAN where the robot wanders around a house and dances and gently strokes a child's cheek
In reality even the best household robot we can build would trip over literally anything or accidentally shatter your ribcage while trying to open a box of cereal

This is something I never considered before, but is a great use case for Dall-E and #AI generated art: as a resource for conceptual diagrams in papers.
Most of us researchers see how beautiful art can sell our research visions but lack artistic skills. These tools could help level the field somewhat.

Since Mastodon saw its initial popularity circa 2017, I've noticed that most users and those reporting on it either don't think about the Fediverse as anything more than Mastodon, or treat its history as beginning with Eugen Rochko and the beginning of Mastodon. In fact, Mastodon is the latest in a long line of federated social networks, going at least back to Identi.ca, and though I wasn't around for all of it,I find this history pretty interesting. (Thread; boosts welcome!)
I've been lurking for a few days, and I think it's time for an #introduction.
I'm a biologist who works on the comparative #biomechanics and #neuroscience of vertebrate copulatory systems. I'm also a science writer and a fact-checker for narrative #podcasts and science magazines.
Hoping to find all the people I followed on the birdsite, and meet new folks, too!
It's finally finished: my new and improved full scale Archaeopteryx skeleton model is done! More stable, easier to assemble and a bit more accurate. Special thanks to Scott Hartman
for the input! Modelled in #b3d, printed on an @anycubic3dprint
