🚨Likely my last reminder ⚠️ 1 week left to register for VEGA26: Nov 18-19 in Berkeley CA, two days of talks and discussions around viral ecology, genomics, evolution, and applications. Check jgi.doe.gov/work-with-us... for the provisional agenda, and cvent.me/e0RnA0 to register (before Nov. 4th) !

This just dropped! A fun conversation about the coral holobiont with @markowenmartin.bsky.social in his podcast #MattersMicrobial Thank you so much for the invite! youtu.be/sO_TPJAHfWM?...

So excited for this program— getting folks with already-great experience into the thick of the carbon-climate conversation.

3(!) climate researchers won @macfound.org genius awards today: @hollyjeanbuck.bsky.social, Kaiyu Guan, Marika Holland! Well deserved. www.macfound.org/programs/awa...

If you care about keeping the Academy of Natural Sciences open to the public in Philadelphia, I need you to read and share this thread. Trish Wellenbach was sent from the mayor's office to oversee the Academy of Natural sciences situation. She needs to hear from us. Here comes the action item:

They warned us Mamdani would impose Sharia law. Instead, he unleashed the real threat: line dancing in Bryant Park.

Good morning, team. We have 3.5 days until Drexel closes the Academy of Natural Sciences. It’s time for you- yeah YOU- to make some calls. Step 1: Tell the following people we need help pressuring Drexel to keep the museum open: Josh Shaprio 717-787-2500 Mayor Parker's 215-686-2181

🏆 AGU is excited to announce the recipients of the 2026 Union Medals, Awards and Prizes; Fellows; and Section Awards and Lectures. Please join us in congratulating these accomplished individuals. spklr.io/63325ETfjN

Truth!

1/17 Submissions are now open for the 2027 Microbial Population Biology GRC! We expect this meeting to be extraordinarily oversubscribed. If you want to come, time is of the essence--apply ASAP! June 27–July 2 • Andover, NH www.grc.org/microbial-po...

Attention Philadelphia! We're hosting a rally to demand that Drexel University maintain The Academy of Natural Sciences Museum open to the public. Join us on Tuesday morning at 10am in front of the academy. Please spread the word, we need all hands on deck! RSVP here: luma.com/1qwnrqz2

The emissions scenarios underlying the next generation of climate model runs that will be featured in the upcoming IPCC 7th Assessment Report are officially out! I have a big new explainer over at Carbon Brief taking an in-depth look at what they mean and whats changed: www.carbonbrief.org/...

🚨WARNING🚨 Today is the LAST DAY to leave your public comment on the NSF Proposal. The Proposal implements some of Vought's Science-Destroying OMB Proposal plans in advance: zurl.co/9nywR Leave your public comment TODAY using our guide & tool: fight2win.standupforscience.net/campaign/Pro...

Three more days to comment on NSF's attempt to smuggle in OMB's already-rejected policies of terminating any grant without cause, gutting civil rights obligations and restricting international collaborations. Submit your comment today! Then call your representatives. 🧪

"I have to say I've never been more shocked by the so-called climate "movement." I don't know what I was expecting, but it wasn't the immediate cowering that so many organizations and politicians are doing" - @amywestervelt.bsky.social drilled.ghost.io/the-problem-...

Anyone else having trouble getting a NZ visa for #ISME20? Submitted mine days ago but it is still pending…now looks like I’ll miss Monday as well as the opening ceremony 😞

Huge faculty recruitment effort at the University of Chicago -- a division-wide, open-rank search looking to hire about 20 faculty across 5 research areas in biology. Come be our colleague! Full announcement: uchicago.app.box.com/s/ckih9zv3rj...

Deep-rooted grasses and forbes should be grown on marginal land on farms that they harvest to produce biochar soil amendment to help their operations become net-zero via Carbon Dioxide Removal. agupubs.onlinelibrary.wiley.com/doi/10.1029/... @jeffinerca.bsky.social

Congratulations to CoE Key Researcher @andreasrichter.bsky.social @cemess.bsky.social @univie.ac.at and ActiveSOIL team Caitlin Singleton @aau.dk, @jeffinerca.bsky.social, LLNL and Michael Obersteiner @ox.ac.uk on receiving €10 million from @novo-nordisk.bsky.social @fwf-at.bsky.social

We composited soil cores and lost 49 AM fungal taxa doing it. Sequencing individual subsamples found them. The ones that vanish are rare, patchy, and phylogenetically clustered. Also drying vs freezing made no difference really. Sample at the scale your question lives at. doi.org/10.1016/j.so...

I just followed this advice to comment on the OMB rule changes. There are about 3 hours left before the deadline (tonight at 11:59p EDT). If you benefit from US Government-funded research make sure to get your comments in. elizabethginexi.substack.com/p/what-we-ne...

🎉 Herzlichen Glückwunsch an @andreasrichter.bsky.social, Caitlin Singleton, @jeffinerca.bsky.social und Michael Obersteiner zum 10 Mio. € Grant der @novo-nordisk.bsky.social für Active Soil! 🌱 @cemess.bsky.social @microbesplanet.bsky.social @univie.ac.at 🌍👏 www.univie.ac.at/aktuelles/pr...

Inspired by an incredible week at #ISVC2026! 🌱 Researchers from 5 continents, 14 countries & 28 institutions dug into soil virus ecology. Huge thanks to our invited speakers: Joanne Emerson, @gtrubl.bsky.social, @karthik-a.bsky.social, @simrouxvirus.bsky.social, and @jeffinerca.bsky.social 🦠

#SOM2026 in São Paulo has been amazing! Huge thanks to the hosts who invited me to give a keynote talk about surprising biology in deep soils Escola Superior de Agricultura Luiz de Queiroz - ESALQ/USP and the CCARBON/USP - Center for Carbon Research in Tropical Agriculture

Great piece by @leahstokes.bsky.social www.sfchronicle.com/opinion/open...

Thrilled to announce that the Department of Microbiology at the University of Washington, School of Medicine is hiring at the Assistant Professor level (tenure-track)! The Pacific Northwest is an awesome place to live and do science 🧪🦠. Join us! apply.interfolio.com/185622 Applications due 8/1.

The next James Bond should be Gary Oldman in his Jackson Lamb persona.

California gubernatorial candidate Xavier Becerra just took half a million dollars from the fossil fuel industry. This on top of the max contribution from Chevron. When someone shows you who they are, believe them.

Devastating loss of Dr. Adriana Romero-Olivares this week. She was an amazing mycologist, a leader in her field, & my friend & collaborator. This is a tremendous loss for mycology, science, & the world. There is a meal train for her husband & two small children www.mealtrain.com/trains/l3kg64

Such heartbreaking news….i have long enjoyed Adriana’s work on fungi and warming, Valley Fever and ways to better engage with the Global South. My heart goes out to her family and colleagues.

In light of the Iran war, the UK will require all new homes to be built with solar panels and energy-efficient electric heat pumps. How...logical! www.cnbc.com/2026/03/24/i...
