Great to see our perspective in print! Chad, Eva, and I suggest that geological and genomic records support the idea that Earth’s first oxygenated habitats formed on the seafloor, especially in shallow benthic settings along continental shelves

Perspective: The oxygenation of Earth's atmosphere about 2.45-2.30 billion years ago may have initiated in the oxidised bottom waters of marine shelves

Our lab is looking for a new PhD student to contribute to research on the early evolution of microbial life with @sanchez_baracal and @LewisAlcott at @BristolUni . Deadline coming-up soon on Monday 19th Jan.

@scientificgio @ISME_microbes Eek!

Super excited to share the first paper published from my PhD, which utilises stable isotope geochemistry and metagenomics to reveal the dominant controls on biological N cycling in Mars analogue systems!

My entire team wrote an opinion paper about Common misconceptions of speciation research. Each section is written by 1-2 team members. The bulk of the writing happened during two writing retreats. It was a lot of fun and I am very happy with the result. https://t.co/4UHcFFODlG

[Dr Richard Kirby @PlanktonPundit]

Some of the amazing, microscopic algae and animals that float at the sea surface. (From my plankton net tows) It is shocking that this vital world of life is so overlooked by natural history TV programmes. In fact, I'd say it is a dereliction of duty. @zeiss_micro

[Joanne Boden @ColoradoJo19]

@lithologuy Enjoyed listening to this last week! Some thought-provoking ideas about life's origins (maybe cryoconite holes should be added to our list of potential places) and intelligent life in the Universe (can it take less than 4.6 billion years to make a space-exploring-species?).

[Joanne Boden @ColoradoJo19]

Proud to be working with some of these role-models, congratulations!

We are pleased to announce that the 2024 GBGM Division awards go to Nagissa Mahmoudi (pre-tenure; @NagissaM), Eva Stüeken (post-tenure), and Alan Kaufman (distinguished career). Check out the full announcement on our website and the thread below (1/10)! (https://t.co/i77aWNnsP2)

I'm hiring a postdoc, for bioinformatics work on amino acid substitution models. I think they are key for understanding biophysics of selection on proteins, mutation patterns, and ancient life, as well as improving phylogenetic methods. https://t.co/qNGlXk6LMM

Some great insights into how RuBisCO has evolved and changed through time, with potential impacts on the efficiency of oxygenic photosynthesis through time!

[Ancient Biology @KacarLab]

📢 New preprint from us! ➡️ Ancestral structure prediction reveals the conformational impact of the RuBisCO small subunit across time

h/t grad student @Kaustubh_2797 and @BrZuviria!

@spacesword13 Congratulations Emma!!!

Are you involved in PhD admissions? Do you advertise projects or assess candidates?

Check out this paper, the latest publication from our Equator project. Doctoral recruitment is often biased against students from marginalised backgrounds- we propose changes to improve equity:

Some really useful advice to share with students for any kind of fieldtrip!

Update: here's a primer and best practice suggestions for discussing toilets and periods on #geology and #geoscience fieldtrips. It's released under a CC-BY-4.0 license, so please share widely with students and staff and adapt as necessary. https://t.co/LqBWyEFVZK

#5 Unless pure olivine minerals were more common during the early evolution and establishment of life on Earth, phosphite from serpentinizing vents probably didn't supply life with the phosphorus it needed to grow.

[Joanne Boden @ColoradoJo19]

Serpentinizing hydrothermal vents have been proposed as cradles for the origin and evolution of life on Earth, but did they also supply early microbial communities with phosphite?

https://t.co/cCGggxM5sX

[Joanne Boden @ColoradoJo19]

#4 Geochemical models made to simulate the chemical reactions which occur in serpentinizing vents calculate that little phosphite can be produced, and to generate any at all requires precise temperatures, lithologies and water:rock ratios.

[Joanne Boden @ColoradoJo19]

#3 We found that microbes were equipped with genes to access phosphite at some of the serpentinizing sites, but not others. We think this might be because phosphite isn't emanating from the vent itself.

[Joanne Boden @ColoradoJo19]

#2 @sanjoymarcel, @wbrazelton, Rika, Eva and I investigated by characterizing the phosphorus-uptake capacities of microbial communities at four different serpentinizing hydrothermal vents.
