i do not care about "the future of the democratic party" as discussed by professional-class bozos who cannot see beyond their next client. i care about not living under a military occupation that is disappearing my neighbors

disappointed that @biorxivpreprint.bsky.social is implicitly endorsing the use of LLMs to replace scientific thought

@richardsever.bsky.social this is a short-sighted move and a net negative for science

IT'S HAPPENING! 💥 I'm psyched to launch the collaboration between @qedscience.bsky.social & @openrxiv.bsky.social @biorxivpreprint.bsky.social! Preprint + q.e.d = your science is out there, and anyone can appreciate it. Let's care about making discoveries, and not on “getting published” (1/3) 👇

Hi all! I am seeking an ecology or applied math PhD student interested in quantitative ecology, specifically ecological theory, food web modeling, or population dynamics. If you are interested, have a look at our lab website below and reach out to me.

An update from the team on the uncertain future of our program and the impact of NSF budget cuts. Please share and reach out 🦠

Some difficult news from the team:

In NSF's FY25-26 Budget Request to Congress, we learned that our program will take a whopping 50% cut - meaning that in September, we'll be $1.25m short of an operating budget that currently supports a cohort of seven PhD students, four postdocs, and three full-time staff.

Verena is one of the largest and last pandemic prevention-focused programs in the United States: since 2020, we've supported the training of over 60 postdocs, graduate students, and undergraduates. Our researchers have established unique laboratory resources for studying animal immune systems, and discovered new antiviral immune adaptations in bats; developed risk assessment algorithms for wildlife and livestock viruses, and diagnostic algorithms for viruses like dengue, Ebola, and Zika; and quantified the effects of climate change, deforestation, and factory farming on spillover risk. Everything we develop is 100% open source, and our data has supported the research of nearly 150 external researchers in 21 countries to date.

We have three months to make up our budget shortfall. Every dollar spent on Verena supports not just our team, but the community of researchers who use our data, code, and resources. You can help us by sharing this post, and reaching out if you're able to support a unique and vulnerable program. Or just head over to viralemergence.org, and take a look at what we do. 🦟 🦇 🦠

The 2022 release is here, in case others need it web.archive.org/web/20220705...

2022 Release - North American Breeding Bird Survey Dataset (1966-2021)

The 1966-2021 North American Breeding Bird Survey (BBS) dataset contains avian point count data for more than 700 North American bird taxa (species, races, and unidentified species groupings). These data are collected annually during the breeding season, primarily in June, along thousands of randomly established roadside survey routes in the United States and Canada. Routes are roughly 24.5 miles (39.2 km) long with counting locations placed at approximately half-mile (800-m) intervals, for a total of 50 stops. At each stop, a citizen scientist highly skilled in avian identification conducts a 3-minute point count, recording all birds seen within a quarter-mile (400-m) radius and all birds heard. Surveys begin 30 minutes before local sunrise and take approximately 5 hours to complete. Routes are sampled once per year, with the total number of routes sampled per year growing over time; just over 500 routes were sampled in 1966, while in recent decades approximately 3000 routes have been sampled annually. No data are provided for 2020. BBS field activities were cancelled in 2020 because of the coronavirus disease (COVID-19) global pandemic and observers were directed to not sample routes. In addition to avian count data, this dataset also contains survey date, survey start and end times, start and end weather conditions, a unique observer identification number, route identification information, and route location information including country, state, and BCR, as well as geographic coordinates of route start point, and an indicator of run data quality.

It looks like Breeding Bird Survey data has disappeared from ScienceBase. I've found a copy of the 2022 version on the Internet Archive, but I'm curious if anyone downloaded the most up to date data before the administration change?

A LinkedIn comment with text: "We celebrate Christ who MAY HAVE actually been quantum too. He dissappear for 3 days but some scholars think he just shrank down VERY SMALL until he able to find growth ray or pill or liquid (unknown). It a test of our faith to believe in that which we cannot see like molecules or ants.
