In new work by Elizah Stephens, she looks at soil N emissions after wildfires.
Wildfire increased soil NO emissions. N2O emissions did not differ significantly; however, only burned soils produced N2O fluxes that were statistical outliers up to ∼165 × higher.

You wanna know if deeply rooted grasses put more carbon in the ground? "Sometimes you've gotta rent a van and drive around the country..." So said @ericslessarev.bsky.social & team in this wonderful study. 12 sites in central/eastern USA...

We are looking for a candidate to develop a proposal on:
Nitrogen cycling in arid and/or drought-affected ecosystems, with a focus on soil microbial processes (including fungi).

It was wonderful to be there and thank you so much for hosting me! Looking forward to future interactions
“NCAR has played a greater role in advancing weather prediction & atmospheric modeling than perhaps any other single entity in the world,” says @weatherwest.bsky.social
Dismantling NCAR would be “like taking a sledgehammer to the keystone holding up our scientific understanding of the planet.” KH

Lower N emissions were mechanistically linked to lower microbial processing of N as soil moisture decreased under warming. This shows that warming-induced losses in soil moisture can offset expected temperature effects on soil N cycling as the planet warms.
We show that opposite to projections based exclusively on temperature, soil N emissions were suppressed under warming, an observation shared across other warming experiments receiving < 1,000 mm/y precipitation—but not by those receiving > 1,000 mm/y where warming increased N emissions.

Please share with anyone who cares about NSF support for graduate students and take 30 seconds to sign and leave a comment.
The deadline for the 2025 Graduate Research Fellowship Program is about one month away and literally no one can apply. #NSFGRFP

The GRFP announcement from NSF cuts out an entire cohort of 2nd year students from consideration, without warning. This is so deeply unfair that it warrants a formal protest from the scientific community. If someone wants to work with me to craft an open letter and solicit signatures, LMK.
We are witnessing a full blown war on science, public health & truth itself.
Let me be clear: Vaccines have prevented more than 1.1 million deaths, 500 million cases of illness & 32 million hospitalizations.
That's a lot of moms and dads who don't have to bury their children.
GUYS. The comment period for this ends in THREE DAYS. PLEASE if you have even a little bit of time, submit a comment here: www.regulations.gov/commenton/FD...
Let them know EVERYONE should be able to get COVID vaccines. They BACK DOWN when WE PUSH BACK. www.statnews.com/2025/05/20/f...
Everyone needs to understand that dismantling NSF will have devastating long term consequences in our competitiveness and innovation in science, technology and beyond. 1/

Inducing severe water limitation may push drylands across “aridity tipping points” beyond which AOB are not stimulated by excess soil N availability, but AOA contributions to NO emissions persist. This caused nitrate to accumulate in soils, leading to the emission of N2O upon rewetting.
We found that both increasing and decreasing summer precipitation can favor AOB-derived NO emissions when soils wet up at the end of the summer, a period characterized by N loss across drylands.
In new work by Sharon, we studied whether changes in #soil N in response to shifts in precipitation may favor tradeoffs between AOA and AOB nitrifiers and the emission of NO and #N2O 🧪 onlinelibrary.wiley.com/doi/10.1111/...
I am crushed to learn that a brilliant researcher at CDC/NIOSH with decades of expertise and seminal papers on flu virus in respiratory particles and effectiveness of masks has been fired.
Exciting! And likely occurring in soils as well to help explain the rapid reduction of 15N-nitrate to N2O we observe in sunny California deserts. www.science.org/doi/10.1126/...
Very interesting finding: photochemical formation of N2O in freshwater and marine waters.
The N cycle gets more complex. 🧐

Science has learned that grant termination letters went out last night to principal investigators of 29 awards made by the National Institute of Allergy and Infectious Diseases (NIAID), including nine grants that were part of a program hoping to deliver antiviral drugs to prevent future pandemics.
Other terminated grants involved research to develop improved COVID-19 vaccines and to address Long Covid, the mysterious lingering aftermath of some SARS-CoV-2 infections. “The research is being treated like we already have all the answers we will need in the future and that the current vaccines work well enough and don’t need improvement, which we know is not true,” says an investigator involved with one of the NIAID grants who asked not to be named for fear of retribution. “Some of the studies being canceled were attempting to make a pancoronavirus vaccine, which would hopefully be available the next time a novel coronavirus jumps species into humans.”
Folks, very bad news for #LongCOVID. Deep breath.
29 awarded grants to do with COVID and Long COVID have been rescinded by NIH. 🧪

Just heard that Trump is putting an end to atmospheric monitoring site NY67 that is run out of my lab. This is one of the oldest NADP sites in the US, continually measuring acid rain and other pollutants since 1977. Closing it down is tragic.
We strongly denounce the Trump Administration’s latest round of NASA firings and office closures, which will undermine the agency’s ability to carry out its missions to advance scientific knowledge and benefit humanity.
