Quanta Magazine - Microbes Gained Photosynthesis Superpowers From a ‘Proton Pump’ | Quanta Magazine

“Using statistics on the distribution of the diatoms and other phytoplankton with the extra membrane throughout the global ocean, the researchers extrapolated that this boost in efficiency from the VHA membrane protein accounts for almost 12% of Earth’s atmospheric oxygen. It also contributes between 7% and 25% of all the oceanic carbon fixed each year. That’s at least 3.5 billion tons of carbon — almost four times as much as the global aviation industry emits annually. At the high end of the researchers’ estimate, VHA could be responsible for tying up as much as 13.5 billion tons of carbon a year.”

New #research: Can we trace development stages and ecology of a #permafrost thaw lake throughout the Holocene? Using an innovative combination of sedimentary proxies (ancient #DNA, #diatoms, #XRF), @Iza_bai et al. show: Yes, we can!

Long-term evolution of Central #Yakutia's vital #alaas #thermokarst lakes is traced throughout past millennia. This may help understand future pathways of culturally important lake systems!

Nature - Revealing the static and dynamic nanomechanical properties of diatom frustules—Nature's glass lace - Scientific Reports

We've long been making incredible insights from our study of diatoms, microalgae that can be found most anywhere in the world. Their biological structure is encased in silicate shells of such a tremendous variety that it's hard to even properly categorize them.

Now, Skolkovo Institute scientists have used one species to help develop nanomechanical improvements to light, sound, and electrical devices.

#introduction

Hi! I'm a #geology PhD student at University of Turku in Finland. Topic is permanent stratification (meromixis) of lakes caused by saline #mine waters. I published my first paper quite recently, it's open access here: https://link.springer.com/article/10.1007/s10230-023-00915-9

Next up will be paleolimnological proxies (#diatoms ❤️).

Hobbies include #plants, #reading (mostly non-fiction and #fantasy) and I'm hoping to adopt a rescue galgo or two quite soon 😍

I’m super excited by this one. I think, I _think_, this is Amphitetras antediluviana, a new-to-me species of diatom from Cromer. I ADORE their cubic form 🎁 (yes more geometry!)

Oh the wondrous geometry of diatoms! This fabulous triangular number is Triceratium favus.

Can anyone shed any light on this little mystery? Too big to be the diatom Cylindrotheca closterium, my second guess is a dinoflagellate (perhaps Amphisolenia sp.?). What do you think? Any help would be greatly appreciated.

So glad this diatom species is back in my samples. I don’t know why I love Ditylum brightwellii, but I do!

Twisty twisty! This colonial diatom Asterionellopsis glacialis is increasing in my samples. It has been known to bloom around here so it’ll be interesting to see how, when, and if that happens this year.

I could watch the ballet of colonial diatom Bacillaria paxilliferea for hours. Mesmerising!

This is the first time I’ve seen Thalassiosira eccentrica as a joined pair! Can you see the little thread between them joining them together? It’s the little things that get me excited!
