New paper with @beatezein.bsky.social & @jedalong.bsky.social:

⭐A new data-driven paradigm for the study of avian migratory navigation⭐

We propose how the multi-modal multi-scale nature of navigation could be studied w/ data mining, machine learning & AI.

A new data-driven paradigm for the study of avian migratory navigation - Movement Ecology
Avian navigation has fascinated researchers for many years. Yet, despite a vast amount of literature on the topic it remains a mystery how birds are able to find their way across long distances while ...

I've seen some similar projects, but IMO this seems to better capture some of the fine-grained detail

I'm convinced AI is our generation's radium - a discovery with genuinely useful applications in specific, controlled circumstances that we stupidly put in everything from kid's toys to toothpaste until we realised the harm far too late where future generations will ask if we were out of our minds.

VC, founder, dumbass
@Nick_Davidov Asked Claude Cowork organize my wife's desktop, it stated doing it, asked for a permission to delete temp office files, I granted it, and then it goes "ooops" Turns out it tried renaming and accidentally deleted a folder with all of the photos my wife made on her camera for the last 15 years. All photos of kids, their illustrations, friends' weddings, travel, everything. It's not in trash, it was done via terminal It's not in iCloud, it already synced the new file structure. She didn't have Time Machine. Disc recovery tools can't see anything. I called Apple and they pointed me to a feature in iCloud allowing to retrieve files that were saved before but are no longer on iCloud Drive (they keep them for 30 days). I'm now watching it load tens of thousands of files. I nearly had a heart attack.

We're *so* close to some students spending more time to have AI do their work, then use AI to make it not seem like AI and then have AI check it ... all taking more time and money than, you know, doing that actual work.

...then everyone sounds the same. Which means interviews become meaningless, and we enter the next phase in the arms race of "how do I evaluate these people in a way they can't fuck about with using AI"?

But sure. My weakness is that I'm a perfectionist, right? Next!

1. The thing about science that these jokers don't understand is that science cannot be vibe-coded.

Whatever its flaws, the point with vibe coding is that you're trying to quickly make something that sorta works, where you can immediately sorta see if it sorta works and then sorta use it.

“The idea is to put ChatGPT front and center inside software that scientists use to write up their work in much the same way that chatbots are now embedded into popular programming editors.

It’s vibe coding, but for science.”

Should you go to academia or industry for research in AI or cognitive science? It's the most common question I get asked by PhD students, and I've written up some of my thoughts on the answer, as an epilogue to my research-focused series on these fields: infinitefaculty.substack.com/p/on-researc...

Aurora Coolness

xkcd.com/3196/
Comic. My experience seeing the Northern Lights: [Graph: x axis is increasing time, y axis is increasing aurora coolness, going from visible glow on the horizon, color only visible in photos -> sheets and pillars of light, colors faintly visible -> “oh wow, it’s getting really bright now.” -> spectacular ribbons of color spanning the sky and illuminating the landscape. Graph shows dips and peaks over many hours with the topmost peeks for only around 5 or 10 minutes.] [caption] Aurora tip: If you get good views of the aurora, keep watching the sky; you might suddenly get great ones.

Here is a current view of the Matterhorn in Switzerland with bright red aurora and green proton aurora spots.

Solar wind data are turning a bit sour for extreme low-latitude aurora for the U.S., but the system is still pumped up enough for Europe!

Beautiful arch and now you can also see the green, meaning that it's moving southwards. It's green below and red on the top, so if you are far away, ypu only see the red because of the curvature of the Earth.
