Pre-2022 data is like pre-1945 steel.
The flexible principles and cartoon villainy currently in vogue among so many of our narcissistic tech and political leaders could lead the public to sour on AI tools entirely.
NSF LTER program “archived”.
LTER=“Long Term Ecological Research”.
This program has been incredibly successful, incredibly frugal for what they accomplish, and…of course…targeted by evil know-nothings.
My heart is breaking.
I'd be happy to discuss and receive feedback. If this is of-interest, get in touch!
2. Metabolomics IDs specific compounds as key to the microbial drought response
3. Metagenomics indicates that drought-stressed "survivalists" are adapted for more rapid growth - we see evidence in their genome character.
4. We measure how methanotrophy and respiration respond in tandem! (2/3)
Excited to share a new preprint: "SIP-enabled multiomics reveals microbial growth responses to drought and rehydration"
1. We use three forms of stable isotope probing to measure in situ microbial growth under both dry and wet conditions

🌡️ Another day, another record high in Boulder. Sunday reached 82° and was our 10th record high set in the last 12 days.
📖 More historical context: 9 of the warmest 11 March days recorded since 1893 have occurred in the last two weeks... #COWx #Boulderwx #colorado #Heatwave
"Science finds, industry applies" was the motto of the 1933 Chicago World's Fair (minus the awkward "man conforms" bit 😉 )
Former INSTAAR Garrett Boudinot is putting that adage into action. He now leads a thriving climate tech startup built on lessons from his research career.
$2.45 billion NIH grant cuts and ~2300 terminated active research grants were DOGE'd in early 2025

So excited to release this research we've been cooking on for the last 6 months! And huge shout out to @joeyshoyer-yall.bsky.social who led much of the technical analysis. Going to share a couple interesting findings below
take the everclear and put it in a glass science-looking bottle with a hazard triangle :)
I'm with Richard on a lot of this & would also add that pushing for systemic solutions *is* a behavior change. It needs to be collective to be effective, which is a different kind of lift than "many people independently make the same, often costly change for their household."
Assessing the rate that weathering could draw #CarbonDioxide out of the atmosphere requires understanding why lab- and field-based rate measurements differ by orders of magnitude.🔍

The Chinese government’s investment in science comes in sharp contrast to US President Donald Trump’s administration, which has tried to cut science spending since Trump took office in early 2025. Many of those proposed cuts have so far been rejected by Congress. www.nature.com/articles/d41...
"the top 25 list..is dominated by facilities in Turkmenistan...Super-polluting plumes were also seen in the US, the largest detected in 2025 occurring in Texas.. Venezuela (five) and Iran (three) also had multiple mega-leaks.

And if you have not been accepted, understand that this is a VERY weird time for grad admissions. Lack of acceptance may not be due to YOU, but due to uncontrollable factors at the university. Keep trying in the future.
We're hiring a postdoctoral researcher in plant genome engineering with expertise in synthetic biology, gene editing, and omics, with an interest in developing next-generation technologies for plants.🪴🧬
Available immediately. If interested, send your CV!
Feel free to share with your networks.
If he's going to get a national profile on the strength of a younger woman's campaign, I'm going to come out and say it: during his short-lived tenure as a math professor, Biss had an inappropriate romantic relationship with one of his undergraduate students. I was that student.
Meanwhile
"Although the country’s latest R&D budget proposal is the same as the target set in the 14th FYP, China’s spending on science and technology in absolute numbers is rising significantly (...) Today’s 7% represents an absolute annual increment far exceeding that of five years ago”
A single course of antibiotics can have lasting effects on your gut microbiome, with changes that last well beyond 4 years. Three types of antibiotics stood out for their long term disruptive impact (3 at left, Figure)

Enhanced rock weathering (ERW) on agricultural soils is being considered as a carbon dioxide removal strategy. However, uncertainties remain regarding feedstock availability, plant-soil impacts, CDR efficiency, and socio-economic considerations, limiting large-scale deployment. 🧪
Owusu et al. say that either top-down control (e.g. grazing) or nutrient limitation (e.g. N) shape bacterial communities which in turn set DOC levels in the oceans. The EOS piece by @saimamay.bsky.social is a good summary.

Our perspective on ERW -Uncertainties of enhanced rock weathering for climate-change mitigation- was featured in the New Scientist

Would it be possible to plot all directorates on the same plot, normalized to 2024 funding rates (so we get a sense of which directorates may be prioritized?)
