Life knows how to keep going - even if it’s freezing -15 degrees C 🥶 outside. AGU just covered our discovery of ultra resistant ice diatoms gliding into a world record! 🧪🔬Enjoy the story here: eos.org/articles/ice...

Ice Diatoms Glide at Record-Low Temperatures - Eos

New observations reveal how microscopic organisms move through polar ice and illustrate how they may have evolved to thrive in extreme environments.

Did you know tiny algae can "skate" within Arctic sea ice? ⛸️ Our new study in @pnas.org reveals the secret life of ice diatoms: they are actively gliding to navigate the ice! This adds a new dimension to the sea ice ecosystem, revealing an active, dynamic ecological niche. @prakashlab.bsky.social

Save the date 📆 Dyche Mullins and I are hosting the “Cell Biology at the Extremes” session at the #CellBio24 meeting on Monday, Dec 16, 5:00 PM. @ascbiology.bsky.social You’ll learn about the latest cool ❄️ hot 🔥 and ultrafast 💨 cell biology. Kindly supported by @focalplane.bsky.social

Coming to #CellBio24 this year? Posters/Talks/Booths from our lab. Grace, Ray(2), Charlotte, Jiju, Qing are presenting posters, Charlotte, Qing, Ray & Manu giving short talks. Hongquan & Jim/Hannah/Brian/Ken at Cephla & Foldscope booths respectively. Lots of surprises 😱 in store if you find us.

Just another day conducting research with the Prakash Lab @prakashlab.bsky.social: sailing to the Arctic and ice-olating diatoms at -15°C! Talk about a cool discovery ❄️🔬

Our latest discovery of “lowest recorded temperature for eukaryotic cell motility” going all the way down to -15deg C. Come for the crazy cold Arctic & stay for diatoms. Will write longer thread - but enjoy video below of diatoms gliding on frozen ice surfaces. Congrats @zqing.bsky.social & team.

@tuthill.bsky.social I see your frozen walking snow fly and raise you a frozen gliding diatom 😊

Loving all the cool 🆒 puns - keep them coming. We have a tradition in lab to draw a doodle for every group meeting - usually by Rebecca Konte (a resident artist in my lab for last 10 years). Here is the doodle of from last year group meeting as “ice skating diatoms” @abelaer.bsky.social #protistsky

Ice gliding diatoms establish record-low temperature limit for motility in a eukaryotic cell

Despite periods of permanent darkness and extensive ice coverage in polar environments, photosynthetic ice diatoms display a remarkable capability of living inside the ice matrix. How these organisms ...
