- A beautiful, crazy and amazing story of science right under our collective feet. I'd heard when the signal got originally reported but got distracted. It's a great example of what makes science simultaneously fun, important and beautiful.
- Reposted by Fernando PérezYou may have seen this news shared today and wondered why it matters. I could write a long report on the many ways Unidata impacts students, educators, scientists, and institutions. For brevity, allow me to share one small specific example that, until now, I have taken for granted. NetCDF.
- Due to the current gap in funding from the U.S. National Science Foundation (NSF), the NSF Unidata Program is pausing most operations effective 12 May 2025. Nearly all staff will be furloughed until funds from our existing NSF grant become available. For more information, see buff.ly/d2TC1Oy
- Huge thanks to @agu.org for engaging seriously with the current crisis and fighting to defend science! Happier than ever to pay my dues and support the organization.
- Reposted by Fernando PérezKeep celebrating the wins. And keep pushing for more.

- It's hard to take seriously a "critique" of preprints that calls them "anti-science" and doesn't even mention or discuss the arXiv, the foundation of preprints in science. I guess physics, math and computing aren't science anymore, given they collapsed due to the arXiv?
- Who’s with me? #PeerReview ensures the integrity of scientific knowledge. Science isn’t social media, and it’s dangerous to treat it as such. For this reason, I believe preprints serve an anti-science agenda & threaten our fields. Check out my editorial in @ScholarlyKitchen.bsky.social. 🧪 #SciPub

- Reposted by Fernando PérezEver needed to simplify street networks? I did. And it is a pain. So we wrote an algorithm that does that for us. And can do for you, as it is available as a Python package called `neatnet`. Here's a short blog about it - martinfleischmann.net/simplificati... and package - uscuni.org/neatnet

- Reposted by Fernando PérezURGENT ACTION FOR NSF GRANTEES. For current & recent (since 2020) awards, archive your award history this afternoon/tonight. Screenshot/download/print your work in research.gov & alert your partners. We have credible threats to integrity of awards tracking systems (via @jeremymberg.bsky.social)
- 🚨 Practical URGENT tip for NSF grantees: Out of an abundance of caution, I would right now go into Research.gov and… 1. Download your NSF award letters. 2. Print PDF your annual reports. 3. Screenshot the status table for annual reports. NSF is planning maintenance tomorrow to Research.gov

- Reposted by Fernando Pérez🧪 Tip: You have the right to contest a grant termination, even though NSF says you don't. 🧵 On Friday, NSF terminated 402 grants (per Musk's DOGE). The notification letters had one of the most egregious violations of fed regulations I've seen so far in these cases: "not subject to appeal"
- Here's a copy of an NSF grant termination notice that went out today. "NSF is issuing this termination to protect the interests of the government pursuant...on the basis that they no longer effectuate the program goals or agency priorities." Not subject to appeal. #HigherEd #AcademicSky
- A great writeup - how to use new-ish Python features for cleaner and more robust versions of code I'm sure we've all written many times - dataclasses and typing in a very common use case.

- Reposted by Fernando PérezGrad enrollment will accordingly plummet in fall 2025. A year with fewer grad students may not seem like a big deal, but it is. Individually, limited options will fundamentally alter the trajectory of lives. (2/4)
- Reposted by Fernando PérezI'm going to state something that's obvious at every university: today was the deadline for folks to decide which grad school they'll join in the fall. This probably won't make headlines, but because we don't expect normal funding, universities aren't admitting a normal number of students. (1/4)

- Reposted by Fernando PérezI'm devastated and heartbroken. Staff at the U.S. Global Change Research Program (USGCRP) got the ax. Most likely means the Sixth National Climate Assessment (NCA6) is also cooked. USGCRP was the glue across the Federal family on all things climate - reducing duplication and making efficiencies.
