Our paper on the need for field studies to test ocean iron fertilization as a climate solution is out - please read it, share widely, and let me know what you think!

🌊Check out our new publication on what responsible, next-generation ocean iron fertilization #OIF fieldwork requires: larger & longer field trials, rigorous monitoring, clear safeguards, & community engagement www.whoi.edu/press-room/n... doi.org/10.1177/2976... @cafethorium.bsky.social @whoi.edu

If we turned all the carbon we burn every year into a giant pile of diamonds, it would be as big as 1,100 Great Pyramids of Giza. Every year.

Re-upping this piece by @mrmattsimon.bsky.social in @grist.org back in August about #OIF for #mCDR. Good work @smith8272.bsky.social and @eschwaab.bsky.social for your quotes in the article. @cafethorium.bsky.social

For CTENOPHORE DAY, a little survey: Which end of this fishing Pleurobrachia is the mouth on? Please just "vote" in the comments — no definitive answers. 🦑🧪🌊 P.S. this is one of my earliest #ctenophore photos, shot on film in a home-built kreisel. P.P.S. Legit data-gathering for a future paper.

The Northern Pacific Ocean is currently smashing temperature records. And it is reaching these levels far earlier than the current generation of climate models had expected. A short thread 🧵

Of all the stupid things that this regime has done, this is right up near the top. Postdoctoral researchers come to the US on H-1B visas. This will further destroy the US science enterprise. Stupid stupid stupid.

I can't stress enough how close U.S. science is to the cliff. "Numbers released in May by the National Science Foundation (NSF) indicate that if Congress approves the cuts to the agency proposed by the White House, the number of early-career researchers it supports could fall by 78%" (@science.org)

‘It’s a nightmare.’ U.S. funding cuts threaten academic science jobs at all levels

“There is a lot of pressure to essentially leave the country or not pursue research,” one Ph.D. student says

Terpenoid production can be engineered and optimized in Phaeodactylum tricornutum - a promising chassis for bioproduction. Excellent keynote by @michelefabris.bsky.social @ #MLD8

I’ve assumed that the diatom fossil record was more helpful in resolving early diatom evolution than it actually is. Karolina Brulka sets the record straight at #MLD8, revealing that Lower Jurassic Pyxidicula fossils were most likely calcareous nannofossils www.nature.com/articles/s41...

Day 3 of #MLD8 started with an awesome plenary by @sinkingdiatom.bsky.social - identifying the “slow burning fuse” of diatom evolution, punctuated by three pulses of accelerated evolution. Definitely a seminal and must-read pub if you haven’t come across it yet www.pnas.org/doi/full/10....

The oil-producing diatom Fistulifera solaris had an interesting evolutionary trajectory. Two species that diverged from the last F. solaris common ancestor millions of years ago, re-hybridized ~0.12MYA which underlies the current allodiploid genome. Hikaru Tago at #MLD8

In Pseudo-nitzschia, only 20% of the cells engage in sexual reproduction, but scRNA-seq shows they are all primed and ready to go. Antonella Ruggiero at #MLD8

Using sexual reproduction markers identified from scRNA data, Arthur Cleyman developed new tools to transform Cylindrotheca closterium and make “pheromone sensing” lines. Cool 😎 #MLD8 @gustbilcke.bsky.social
