We are losing stars one streetlight, one neon sign, one suburb at a time For most of human history, the night sky has been a shared inheritance, a source of wonder. Now, more than a billion children see barely any stars in the night sky above their homes. So what does that...

“You understand your place in the universe very quickly when you look at something 1 billion light-years away … and realise that those photons, they predate dinosaurs, they predate humans, they predate the continents,”

The question for me that seems to have been forgotten or passed over is why did the Queen pay £12m to Virginia Giuffre if she believed Andrew was innocent?

I’m fine with *exploring* the solar system, with robotic probes and some crewed vehicles.

But that’s not the same as trying to live there…

Weird how this, the ultimate 'rape gang', isn't making the front page of the Daily Mail - especially since almost all of the redacted documents can be read.

No one says to legit business owners, "hey I see there's an underground market selling toxic knock-offs of your product: how will you incorporate the toxic product AND protect your customers against its harms?" But apparently it's fine to make this suggestion to educators with respect to AI.

I know disciplinary standards differ, but I've been at this for decades and I've never cited a paper I didn't read. Didn't like, sure; didn't understand, often; kind of drifted off in the middle there, it happens. But didn't read at all? Nah. Come on.

Evolutionary ecology of animal memory | TREES DLA This project seeks to explore how memory evolves in response to the ecological tasks that animals face in their natural environment. Associative memory exists in some form in almost all animal species...

It's not asylum seekers who jack up rents, undermine the NHS, hold down wages and keep people insecure.
It's capital.
The role of the far right is to shift the blame for decades of economic attacks by the rich and powerful onto powerless people who have only just arrived here.

This is just getting ridiculous. Nothing that has happened (or is reported below the headline to have happened) this weekend remotely justifies talk of an explosion or mass protests. The media are confecting a crisis, and, in some sections of it, hoping to provoke one. 1/3

This is maybe the worst part about being an educator in the AI era.

AI companies are *stealing your time* by making you work around it/find it/adjudicate it. Time that, 4 years ago, you would have used to improve your materials, or stay up-to-date on some area of research.

AI thrives where education has been devalued | The Observer A culture that views knowledge as a means to an end invites the misuse of new technology

“It is less that AI is the cause of degradation in reading and thinking, and more that the creation of a culture that views knowledge primarily in an instrumental manner has made it easier to misuse AI.” My ‪@theobserveruk.bsky.social column: observer.co.uk/news/opinion...

The depressing, awful reality of where we are as a society.

Two graphs from the paper. 

The left graph shows US net greenhouse gas emissions from 1990 to 2022. The official EPA estimates decline fairly steadily from 6.6 gigatonnes per year in 2005 to 5.5 in 2022 (17% below 2005 levels), largely reflecting natural gas displacing coal for electricity generation. The adjusted estimates, which reflect independent measurements of methane emissions from oil and gas infrastructure, end at 6.3 gigatonnes per year in 2022 (only 5% below 2005 levels).

The right graph shows 2022 emissions increasing linearly with the assumed global warming potential of methane. Climate scientists are divided on whether to use the 100-year GWP, 20-year GWP, or something in between. With methane warming impacts assessed via the 20-year GWP, the central 2022 emissions estimate is 7.9 gigatonnes per year - 20% *above* the EPA's official 2005 estimate.

Caption: Figure 1: Left: United States net greenhouse gas emissions over time. Right: Scaling of 2022 net emissions with methane’s GWP. After adjustment to reflect recent measurements of methane emissions from natural gas infrastructure, United States net emissions remain nearly as high as their 2005 level.

New paper. I wish this wasn't the case, but most progress on reducing US greenhouse gas emissions is likely spurious. Why? EPA underestimates methane emissions from oil and gas. Relevant today as Repubs vote to gut IRA's methane monitoring/mitigation program. 🧵
