Deep sea phytoplankton observed ballooning to 6x their size in order to float to the surface to capture sunlight. @CurrentBiology Learn more: cell.com/current-biolog… @Planktonico @ManuPra18599785 @PrakashLab
Free scientific illustrations for biologists! 😍 @NIH has released a library of 500+ free scientific illustrations to create figures, presentations, and illustrations! all freely available in the public domain. Retweet and spread the message! bioart.niaid.nih.gov
Check self-deployable, adaptive robots (arxiv.org/abs/2410.02974) based on Contracting-Cord Particle Jamming (doi.org/10.1039/D4MH00…). These robots hold potential for exploration in remote, complex areas. Accepted to ISRR2024. #softrobotics #AdaptiveRobotics #ParticleJamming
Invited talks by Michael Shelley (@Michael80429772) and Senthil Arumugam (@dopaminator). Session organizers: @koslovergroup, @ajay_gopinathan, @RayChang0612 Submit abstracts to session #04.01.04: summit.aps.org/attend/sorting…
Interested in how cells transport signals and material among their own compartments or to other cells? Join us at the 2025 APS March Meeting Focus Session on Intra- and inter-cellular transport! Abstracts due Oct 25.
Most birds use a funny running style: grounded running. It's a paradox: GR costs more energy than normal running, but animals usually minimize costs. Do birds waste energy? We resolve this with a model of the emu (the best bird). 1st PhD chapter, out in @ScienceAdvances 1/17
What if you could deliver molecular tools directly into oocytes without microinjection? In our new paper, online today @Dev_journal (doi.org/10.1242/dev.20…), we introduce VitelloTag, a new cargo delivery tool to enable injection-free genome editing. 👇Read on for a short 🧵
Congrats to all the Prakazoans who celebrated today with doctoral degrees. @Eliott_Flaum @RayChang0612 Anton Molina Jerome Nowak @hongquan_li Since I could not do the formal hooding ceremony, we ended up doing a hooding on Kilo Moana (first graduation on a boat I am told)
Congratulations to all of our graduates! Today the Stanford Engineering community gathered to celebrate the conferral of 765 bachelor’s degrees, 1,291 master’s degrees, and 330 doctoral degrees to the class of 2024.
The tiny predator Lacrymaria olor owes its shape-shifting ability to an “origami-like” cellular architecture, a new Science study finds. The results offer a glimpse into geometrical control of behavior in single cells. Learn more in this week's issue: scim.ag/7eu
Thrilled to announce that I will be joining the faculty of Polymer Science and Engineering at the University of Massachusetts Amherst in 2025 @UMassAmherst! And SO grateful for the many friendships/future collabs that budded (across many universities!) this interview season. 1/11
It has been an amazing 5 years with you @PrakashLab! Hard to summarize what I learned from you -- from science to curiosity and your commitment to society. The story goes on. Praise the Lord!
(1/2) Congrats Dr. Dr. Ray Chang @RayChang0612 (not a typo, he is also a MD) - spectacular thesis defense from the lab on “ultrafast cellular biophysics”.. the breadth of ideas and discoveries (a new non-dimensional number and scaling law, discovery of topological damping..
Our new paper in @elife: Fluid mechanics of luminal transport in actively contracting endoplasmic reticulum doi.org/10.7554/eLife.… Purely theory/simulation-based exploration of (im)possible ways to generate mixing currents inside the ER network
My take on Ettienne's famous drawing in 1970! Thank you Rebecca for the fun group meeting today!

Excited to release arxiv.org/abs/2307.11827, led by @abigail_plummer & former undergrad Caroline Adkins in collaboration with Andrej Košmrlj! We studied how the growth/expansion of a body is altered (often in surprising ways!) by obstructions. 🧽🎆 Tweetorial follows... [1/11]
What's your favourite #protist? Magnificent protist image resource from Yana Eglit & @pjkeelinglab just out in @PLOSBiology journals.plos.org/plosbiology/ar…
(1/n) In case you still want to make some Diwali Rangoli - and want to explore a new kind of "topological trap" in spiral active matter - enjoy this hypnotic thread from latest story from the lab #DFD2023 Read details here: arxiv.org/abs/2305.12572
Excited to share our GFM video at #APSDFD2023! It’s been so fun to study the hydrodynamics of marbling art while doing some marbling! Huge thanks to Prof. John Bush and @SaverioIV! And my advisor Chris Rycroft for inspiring this work 3 years ago. youtu.be/yzlPvtDmtAE
The jamming of components inside a rapidly contracting Spirostomum ambiguum cell could protect the organism from internal damage, according to results from @PrakashLab @ManuPra18599785 @Stanford Story by @KatSkipps physics.aps.org/articles/v16/1…
Beautiful news piece on our discovery of “topological jamming” inside a cell. Original paper: pnas.org/doi/abs/10.107… I discovered spirostomum strange abilities first with #foldscope around Lake Tahoe (w/my kids). If we keep eyes open, wonder what we find. Congrats @RayChang0612
