"Day 127, orbit 1968 — That aurora was absolutely spectacular… shimmering and dancing beneath us, stretching as far as the eye could see, and so intense it lit up the Station in shades of green 💚", says @esa.int astronaut Sophie Adenot.   📸 ESA/NASA – S. Adenot #εpsilon

This is a great study and (one of?) the first of its kind! A note of caution from a human contributor though: given the slow academic publishing process, the findings should primarily be interpreted as a snapshot of AI capabilities (and the capabilities of researchers using AI) in 2024. (1/4)

1/ Can AI help researchers check whether published social science results actually reproduce? In our new PNAS paper, we tested this directly in the AI Replication Games: 288 researchers, 103 teams, and real replication packages from quantitative social science.

Thought provoking science commentary: "AI models assume that relationships remain stable over time, that training data are representative of future conditions, and that observations are independent. These assumptions are routinely violated in ecological systems." www.pnas.org/doi/10.1073/...

Thought provoking read about how climate impacts running and how running impacts climate change. “Runfluencer culture and over-consumption in running fashion are dramatically increasing the environmental cost of what should be a low-impact activity. #HowWeKitUp theconversation.com/hurdles-to-a...

Hurdles to a hobby: How climate change and ‘runfluencer’ culture impact our daily jog

Climate change is already re-shaping how people engage in sport. Due to warming temperatures, running may become less accessible and safe for many of us.

The Atlantic’s “conveyor belt” is slowing. New observations from 16.5°–42.5°N show a two-decade, basin-wide decline in deep western overturning, the first robust observational evidence that the AMOC is weakening, confirming long-standing model predictions. www.science.org/doi/10.1126/...

Meridionally consistent decline in the observed western boundary contribution to the Atlantic Meridional Overturning Circulation

Western boundary observations in the Atlantic suggest a meridionally consistent decline in the ocean overturning circulation.

1/ Forget tales of escapees from the film set of The African Queen. Ignore rumours of Jimi Hendrix’s supposed liberation of a pair on Carnaby Street. Newly declassified documents from the Ministry Of Defence reveal how Ring-necked Parakeets colonised the UK through Operation Norwegian Blue! 😮 🪶

A close up image of the head of a Ring-necked Parakeet showing its bright green plumage and red bill. Wording alongside reads: Origin of the UK’s Ring-necked Parakeets finally revealed!

I just did the dumbest thing of my entire career to prove a much more serious point. I tricked ChatGPT and Google, and made them tell other users I’m a competitive hot-dog-eating world champion People are using this trick on a massive scale to make AI tell you lies. I’ll explain how I did it

Bluesky is the new science Twitter, new study by @whysharksmatter.bsky.social and Julia Wester concludes! "Results show that for every reported professional benefit that scientists once gained from Twitter, scientists can now gain that benefit more effectively on Bluesky than on Twitter."

Scientists no Longer Find Twitter Professionally Useful, and have Switched to Bluesky

Synopsis. Social media has become widely used by the scientific community for a variety of professional uses, including networking and public outreach. For

Happy New Year! 🎆 As expected, sadly, the radars once again lit up with MILLIONS of birds fleeing from #fireworks. GIF of the @knmi.nl Herwijnen radar See other years: horizon.science.uva.nl/fireworks/ Thread and more science below 🧪🪶

Another NYE, another night of terror for millions of birds across the Netherlands (and around the world). Last year we published in @ecologicalsociety.bsky.social Frontiers 🧪 about the massive impact of fireworks on birds 🦅. Paper: doi.org/10.1002/fee.... Thread below 🧵👇
