Early Humans Weren’t Apex Predators—They Were Eaten by Leopards
Homo habilis was thought to be the first hominin to use stone tools for hunting and processing meat, but they might have been prey instead of predators.

The 2025 Roadmaps for the US Magnet Development Program
The US Physics community completed the Snowmass planning process in 2022, culminating in the HEPAP Particle Physics Project Prioritization Panel (P5) publishing its summary report at the end of 2023. Building on this, the US Magnet Development Program, a national accelerator magnet R&D program established by DOE-OHEP in 2016, has updated its strategic plan to align with the 2023 P5 report, resulting in this roadmap document.

KI aus Deutschland: Hingewurschtelt in Germany - Golem.de
EU-Milliarden fließen in KI-Projekte, doch es kommt wenig dabei heraus - gerade in Deutschland. Das liegt vor allem am falschen Fokus.

Hemingway in For Whom the Bell Tolls: "He had heard these people talk many times and he thought what they said was often beautiful and fine to hear but he did not like them. It is not liberty not to bury the mess one makes, he thought. No animal has more liberty than the cat; but it buries the mess it makes. The cat is the best anarchist. Until they learn that from the cat I cannot respect them."

Ok, yeah, I'm not done processing my anger over liberals doing shit like this. So this historian sees a rise in right wing violence, sees the US government carrying out ethnic cleansing, sees a rise in white supremacist terrorism, and then says, "oh yeah... this reminds me of a time right around the 1920s. Hum... yeah, ANARCHISTS fighting the government! Yeah, that's the same thing."
FFS, IT'S THE RED SUMMER! If you want a parallel between today and some horrible time in US history, TALK ABOUT THE RED SUMMER. The point of the language of dehumanization that the right uses, the point of all the anti-black and anti-emigrant rhetoric, is that it leads to genocide. Trump already carried out an act of genocide (#USPol

EGRORIAN: Apparently not. Can I offer you some refreshment? Everything here is reconstituted, of course, but it remains palatable.
AVON: We came here to talk, Egrorian.

Advancing 1D thermo-hydraulic tools for large cryogenic facilities
The Cryogenic Division at Fermilab develops large-scale cryogenic systems for particle accelerators and superconducting magnet test facilities. To support design and diagnostics, a Python-based code was created to calculate pressure drops in components such as valves and pipes. This paper presents recent enhancements to the code, including new heat transfer functions that improve the accuracy of thermal and hydraulic predictions. The first application models pressure and temperature changes in …

Series D, Episode 03 - Traitor
VILA: He's not the man for the job. Tarrant has about as much subtlety as a Tarzian Warg Strangler. All I'm saying is Tarrant's going to walk straight into trouble and get himself killed or captured. If he's dead he can't talk. But if the Federation find out we're hanging around, we won't stand a chance. Not in this ship. At least in the Liberator we could always outrun them.
AVON: Vila, if the Federation do have some ne…
