First seen shared on Mastodon. Glorious. apod.nasa.gov/apod/ap26090...
An image of the sky in vertical segments, each advancing time as the sun lowers in the sky. Each time slice is a period of the recent solar eclipse waxing from left to right, so the segments darken and change colour. The full eclipse is a black stripe with striking bright ring in the centre of the image. The slices then continue, with the eclipse waning, into a red sunset.

Was literally about to reply with this...
Two novelty candles of the Nazi leader Toht from Raiders of the Lost Ark, screaming. One of the candles is half melted like the character at the end of the film.

Just back from the framers: a wonderful print from @ciaraioch.bsky.social. Brendan the Navigator, and a line from the traditional prayer to him.
A framed print of a painting - dark sea at night, faintest hint of light on the horizon. The bright wake of a sailing coracle with St. Brendan's cross lights the lower third of the image, and in fine white paint in the night sky is a quotation from a traditional prayer to the same saint: "I will trust in the darkness."

"Wind and solar, supported by battery arrays and e-fuels, are now the cheapest, cleanest sources of energy in history. Last year, Ireland alone added 1GW of new solar capacity, meaning we now have at peak a total of 8GW of green electricity, or the equivalent of five [nuclear] plants"
Wind and solar, supported by battery arrays and e-fuels, are now the cheapest, cleanest sources of energy in history. Last year, Ireland alone added 1GW of new solar capacity, meaning we now have at peak a total of 8GW of green electricity, or the equivalent of five Olkiluoto plants.

To grasp the exponential nature of renewable energy roll-out, consider that in 2004, a total of 1GW of solar was deployed globally. Last year, the same amount was added every 12 hours.

Some progress but more to do on the psych's WEIRDness Martingano, A. J., Trivedi-Bateman, N., Gauger, L., Huggett, M., Allcock, B., Jackson, R. E., & Holschuh, G. (2026). Still WEIRD, still underreported: An updated benchmark for psychological science. American Psychologist doi.org/10.1037/amp0...
Psychological science has long been critiqued for relying on samples drawn primarily from Western, educated, industrialized, rich, and democratic societies. The present study examines the current state of this critique by integrating three lines of evaluation: national sample origins, demographic representativeness, and adherence to American Psychological Association reporting standards. We analyzed all human subjects research published in 2024 in six leading psychology journals (k = 1,217) and compared their samples with previous reviews. While the proportion of U.S.-based samples continues to decline, U.S. participants remain vastly overrepresented (59% of samples in 2024). For demographic representativeness, we found substantial improvements in demographic reporting since 2014, but participants’ race, ethnicity, socioeconomic status, and education are still frequently omitted. For reporting standards, we evaluated compliance with  journal Article Reporting Standards for Race, Ethnicity, and Culture (APA, 2023). We find wide variation across journals in the adoption of practices, with some, such as including sample justifications, almost unanimously adopted, whereas others, such as conducting analyses of diversity, are much less common. Overall, our findings show that  psychology still depends heavily on Western, educated, industrialized, rich, and democratic samples, with only modest and uneven progress toward inclusivity and transparency. By combining three evaluation  criteria, we establish a holistic benchmark that can be used to systematically monitor change in these research practices in the future.

Heading to Dublin on Wednesday and you should always have something sensational to read in the train. Looking forward to getting stuck into @tonychemero.bsky.social 's latest.
A physical copy Tony Chemero's new book, "Intertwined Creatures" sitting on a desk littered with mouses and trackpads. The cover is a complex image - simultaneously kaleidoscope, organic, and multi-symmetrical. An intricate radial pattern evocative of fruit and seeds, cells and nerve tissue, and the continually unfolding movement of a kaleidoscope.

Larson was a prophet.
A Far Side cartoon by Gary Larson. A cartoon cow stands on its hind legs behind a table of bizarrely shaped objects: a blob that might be a strange stone, a second like a mix between a chicken drumstick and a rock, a long twig, and a weird saw made of bone or something else organic.

Denzel bringing in home in Unstoppable and, arguably, Deja Vu too (though does the ferry count?).
The movie poster for the film "Unstoppable" featuring the faces of Denzel Washington and Chris Pine, amid action shots of them both between moving train carriages.

Movie tagline: "1,000,000 tons. 100,000 lives. 100 minutes."

I guess this one might count as a bit obvious, but was a book that turned me on to biographies in general.

We and our students can choose not to use these technologies. Just like we have banned smoking from public spaces, we could foster that process of banning both by choosing to individually quit smoking and by demanding regulation of the tobacco industry. Hence, we can also choose to unshackle ourselves and others from harmful technology industry frames, products, and lifestyles.

Five principles to protect the human knowledge ecosystem 5/5
Responsibility precludes scientists from using AI products whose use is irresponsible, e.g. harmful to people, animals, and the environment, or otherwise in violation of legal guidelines (e.g. copyright, data privacy, labour laws, Butterick 2025; Cole 2025; Rijo 2025; Tafani 2024a). Minimizing harm is vital for both engineers (ACM Code 2018 Task Force 2018) and theoreticians (Guest 2024).

Five preoccupied to protect the human ecosystem 4/5
Independence means that scientists ensure that their research is unbiased by AI companies agendas, and that any potential conflicts of interest are declared in publications and other public communications (this also follows from Honesty and Transparency; cf. Mohamed Abdalla and Moustafa Abdalla 2021; Atkin 2025; Forbes and Guest 2025; Knoester et al. 2025).

Five principles to protect the human knowledge ecosystem 3/5
Transparency requires that the AI technologies are open source and computationally reproducible.
Here we must recall the technology industry’s obfuscatory tactics: “the name of the current producer of ChatGPT. ‘OpenAI’ sounds like it is engaged in open science, but as we have now seen, ‘open’ never really means what you think it does.” (Mirowski 2023, p. 738; see also Dingemanse 2025; Hao 2025; Jackson 2024; Liesenfeld and Dingemanse 2024; Liesenfeld, Lopez, et al. 2023;

Five principles to protect the human knowledge ecosystem. 2/5
Scrupulousness demands, among other things, that scientists only use AI products whose functionality is well-specified and validated for its specific scientific usage (cf. Kwisthout 2024; Kwisthout andRenooij2025).Thisincludesterminologicalprecisionaboutwhatformalisms,models,and/or technologies are used (recall Figure 1) and rigorous argumentation to motivate why these technologies are appropriate for the scientific purposes at hand.

Five principles to protect the ecosystem of human knowledge. 1/5 @tomstafford.bsky.social has argued that the infoglut we live in is like when densely populated cities made plagues more likely. We need to normalise new hygienic practices. @olivia.science et al set some out.
Honesty implies that we do not secretly use AI technologies without disclosure, and that one does not make unfounded claims about the presumed capabilities of AI technologies (this also follows from Responsibility; see example from MIT Economics 2025, where perhaps too little too late was done).

"But AI tools will be just like calculators..."
we ban calculators when teaching children addition and other basic arithmetic operations for a reason (cf. Lodge et al. 2023). Otherwise, they would not learn these arithmetic operations, and calculators do not help to understand the basic mathematical rules. For the same reasons, we also do not allow the use of spellcheck software for children learning to spell, or keyboard typing when learning to write by hand

Students aren't generally looking to cheat, and most think LLM use should not be allowed in college education. Let's not allow salespeople to speak for them.
Technology companies are not shy of falsely claiming that students are lazy or lack writing skills. Such a mantra serves only to sell products — or coverupandexcuseoverworkingthembyourcolleagues—withnoreflectiononreality.We condemn those claims and reassert students’ agency vis-à-vis corporate control.

Why higher ed teaching is hard, and always will be. But we don't do it because it is easy, and we are trusted to do it well because we have hard earned expertise in our fields. Let's not undervalue that, hey?
Students have always cheated. Bending and breaking the rules is human nature. And by the same token, educators are not police. We are not here to obsessively surveil our students — education is based on mutual trust. Therefore, our duty is to build mutually shared values with our students and colleagues.

It is vital that we don't overestimate our understanding of human cognition. Yes, there is reason to believe we have a better grasp of some things than when AI hype first appeared in the 1950s, but that better understanding is not clear, and almost certainly isn't on the basis of simple computation
Although we do not fully understand human thinking, this does not licence attributing thinking to whichever machine or technology, uncritically and through anthropomorphisation. Such arguments from ignorance lack all scientific rigour. The only argument from ignorance that science permits is caution, more research, and care as appropriate actions when something is truly unknown.

Sigh. Paging Sam Altman.
AI hype cycles appear to go hot and cold every few years, it is also rife with valuable teaching moments. For example, a news story like this would not be out of place in the present:

The Navy revealed the embryo of an electronic computer today that it expects will be able to walk, talk, see, write, reproduce itself and be conscious of its existence.

The more I learn about history, the more I understand how important learning about history is. This is doubly important in my own professional field. @olivia.science and colleagues driving home the point against the inevitability of AI reminding us of this.
When we engage with the public, we notice people think that AI, as a field or a technology, appeared on the scene in the last three years. And they experience confusion and even dissonance when they discover the field and the technologies have existed for decades, if not centuries or even millennia (Bloomfield 1987; Boden 2006; Bogost 2025; Guest 2025; Hamilton 1998; Mayor 2018). Such ahistoricism facilitates “the AI-hype cycles that have long been fuelled by extravagant claims that substitute fictionforscience.”(Heffernan, 2025,n.p. Duarte etal.2024).
