How do swimming microalgae move in snow? And how does this couple to climate change? We have a fully-funded @ONEPlanetDTP PhD opportunity to study in my group in collaboration with @mjsandells, @scienceisnotfun and @xanthellaltd. Please RT. More info here https://tinyurl.com/snowalgaeswim
YES! as much as we love sampling - we must also keep supporting culture collections! they do such an important job and are indispensable for fundamental research

Single-celled organism, Loxophyllum, eats a multicellular rotifer! This is almost a 5 years old clip but I thought I could share it today!

The motility of the outer hair cells provides an active mechanism for cochlear amplification helping the inners in their fine frequency selectivity. Their stereocilia are filled with parallel actin filaments and dense molecular complexes at the lower and upper tip-link ends.

How can a single cell learn without a brain? We explore this in my first paper from my PhD with @WallaceUcsf, co-first-authored with @TMakushok! We discovered that gradual habituation in a cell population is due to step-like switches in single cells https://bit.ly/3GNg702

My first #toot on the woolly mammoth thing. I was rubbish at twitter, I'll probably be worse on Mastodon...but here are some neurons as a way of a premature apology :)
@MingqingCai thanks very much for your interest! yes we hope this technology is useful for many different specimens!
@StearnsLab @Mill_lab @jekely
Thanks Tim! Great question! Yes there will always be some boundary effects, depending on whether it's a water-air interface or a solid boundary. In fact we show in the paper that the solid boundary is what tends to align the cell with the wall and makes it swim in circles in our set-up.
But in the end it depends on the question you're trying to answer... if you use a big enough droplet/trap then there's a good chance that behaviour will be largely unaffected. Secondly, consistency is key - so if you're looking at the effect on behaviour of some orthogonal parameter say light or chemicals, then as long as you keep the physical environment the same, it's a valid comparison!

Apparently the alga Mesostigma swims like 'falling leaves'...

かなりマイナーな霞ヶ浦のプランクトン。メソスティグマ(Mesostigma sp.)。陸上植物に近い系統の藻類で、ミカヅキモなどと同じストレプト植物門に属している（メソスティグマ藻綱）。オレンジ色の眼点と、細胞を取り囲む微細な鱗片が特徴。ひらひらと落葉が舞うように泳ぐよ。
