Part of the Vaujany village ('Le Petit Vaujany', 1235 m asl) was temporarily isolated after two avalanches descended on both sides! ❄️🌊

All these point in one direction: the climate is changing, and the rapid changes started after the steam engine was invented and society started using fossil fuels to generate heat and power on an industrial scale.

Perhaps we ought to think about curtailing our use of fossil fuels?

Just an idea.

US applications for prestigious European research grants surge 👇

"…but it is not clear whether Europe has the funds to absorb these extra researchers without increasing competition for existing staff."
(without change in total budget and success rate it will not)

A new fully open-source #AI LM model claims to be more efficient for scientific literature search and synthesis.

I tested their online portal with a few questions on tectonics and/or earthquakes and, hmm, it worked very badly… 1/2 ⚒️

I don't say this often but: I'm so proud to be a climate and environment reporter. We cover an issue that is vitally important to humanity and the natural world. 14 of my climate colleagues at the Post were laid off today and I'm devastated.

The killing of Alex Pretti is a heartbreaking tragedy. It should also be a wake-up call to every American, regardless of party, that many of our core values as a nation are increasingly under assault.

Videos verified by The New York Times show the man federal agents shot and killed in Minneapolis on Saturday was holding a phone, not a gun, before the agents took him to the ground and shot him. At least 10 shots appear to have been fired within five seconds. www.nytimes.com/interactive/...

This is Alex Pretti.

This morning he was murdered by ICE. Six ICE agents held him down and shot him at point blank range. Alex was a nurse and researcher at the VA.

Our thoughts are with his loved ones and we stand united in action calling for the abolishment of ICE.

Two different agents are visibly firing their guns, with at least 10 shots being heard in total. Most of them are fired after a brief delay, when the man is already lying motionless on the ground. The current videos of the shooting only show these two agents with guns drawn.

I asked this to a generalist #AI chatbot (LeChat):
"I have a question about your training data and scientific articles you can access / read. I see that you can cite articles openly accessible on the web. Do you have access to the thousands articles that are under paywalls?"
Answer NO 👇

1/3 ⚒️ 🧪
Screenshot of chatbot answer. Verbatim: Great question, Robin. My training data includes a broad range of publicly available texts up to November 2024, but I do not have direct access to scientific articles behind paywalls. Here’s how it works: Open Access Articles: I can cite and reference articles that are openly accessible on the web, such as those published under open access licenses or available on preprint servers like arXiv, bioRxiv, or institutional repositories. Paywalled Articles: I cannot access or read articles that require a subscription or payment to view. If you provide me with the text or key details from a paywalled article, I can help analyze, summarize, or discuss it, but I cannot retrieve it myself. If you need information from a paywalled article, you can: Share the text or key points with me, and I’ll help you work with that content. Use your institutional access (e.g., through CNRS) to obtain the article and then share relevant details with me.
