@carolinamicro.bsky.social Huang & @lbobay.bsky.social investigated genomic rearrangements across 121 microbial species, showing that rearrangements occur at a variable pace across bacteria and archaea, pointing to different selective constraints.

Congrats to @carolinamicro.bsky.social for leading this study! We looked at genome rearrangements over short evolutionary timescales. Among other things, we found that genomes are highly syntenic within most species. However, several bacteria experienced sudden and massive genome rearrangements.

Please apply if you are interested in environmental microbiology topics such as microbial dark oxygen production and methane cycling under oxygen depletion.

The idea that the president can randomly fire everyone in the administrative branch is toxic.
It’s enabling a slash and burn mentality across the federal government. What will be left in a couple of years?
Is anyone reporting on what’s going on at NASA?

If you're at #ASMicrobe, come see us today! I'm up at 8:15 in 403B, and our grad students: @oceancait.bsky.social at 9:15 in 403B and @astrobio-agb.bsky.social also at 9:15 in 402AB.

I'll be scrambling between the two rooms to see them!

Tomorrow at 12:45-1:30 in the EEB Track Hub in the poster hall #ASMmicrobe I am talking about microbial diversity including Asgard archaea, and an expanded tree of life from marine sediments.

At ASM Microbe? Check out @drmartinezrabert.bsky.social poster EEB-SUNDAY-1162 - “Exploring Earth's Atmosphere as an Active Microbial Ecosystem Using Thermodynamic Principles and Bioenergetic Modeling” on Sunday 🦠🌥️⚡️🧬 @hfspo.bsky.social @asm.org #ASMicrobe

Wow, @tallcuppajoe.bsky.social, spot on design for the shirt this year 🎯 totally not biased, of course 🤭 #asmmicrobe #binningsingletons

Hi #ASMicrobe go-ers!! I am convening a session tomorrow @8:15am PDT! (I may be half asleep bc my ✈️ gets in at midnight)

This session is about metal homeostasis in environmental 🦠 and includes topics like lanthanide metabolism, cable bacteria, Mn-oxidizing fungi, metal stress, and more!

#MicroSky

Attn ASM 2025 attendees interested in Mars, astrobiology, and sample return! I'll be speaking Fri June 20 (10:45am, AES Track Hub, Exhibit Hall) on the frontiers of microbial life detection in context of (potentially) returning samples from Mars. Hope to see you there! #ASMicrobe

A short thread about the people in my lab who will present posters and give rapid talks at #ASMmicrobe: 🧵

Oh wow. @nanoporetech.com has last minute canceled their participation in #ASMicrobe. This is sad. 😔 Wow.

How a discovery in Yellowstone National Park led to the development of PCR - Richmond Scientific A discovery in Yellowstone National Park led to the development of PCR, the gold-standard COVID-19 tests used to fight the global pandemic.

Reminder: Nobel-prize winning PCR (1983), used in basically all genetic tech today, was only possible because of extremophile bacterium discovered in 1964 in Yellowstone funded by a small ~$80k NSF grant with no obvious application at the time. #science 🧪

For non-scientists: the funding rate is somewhere between 7% to ~25% (rare) for NIH or NSF grants, depending on where you are applying. Grants are reviewed by a panel of peers who read the grants, score them, then debate the ratings for 1-2 days to rank them. It is INCREDIBLY competitive already.

Another casualty of Trump cuts? California students pursuing science research careers At least 24 UC and Cal State campuses lost science research training grants that provided their students with annual stipends of $12,000 or more.

CalMatters just released an article about our lab's students that have been affected by the funding cuts 💔 Thanks to the journalists for amplifying their voices.

Upset about the President's budget request to eviscerate NIH, NSF, and all science in the US? Call your representatives! Push back - 77% of Americans recently polled do not want to cut research funding. The cures and economic benefits from research are popular - don't let your reps forget that. 🧪

Exclusive: Trump team freezes new NSF awards — and could soon axe hundreds of grants The National Science Foundation is the latest US agency to be disrupted by Elon Musk’s DOGE.

While I was trying to wrangle reports of signs of life beyond Earth, @dangaristo.bsky.social was reporting on how ALL NEW RESEARCH GRANTS ARE BEING FROZEN AT THE NSF 🧪
