I found this ring in the parking lot this morning.

I was going to turn it in at the information office, but I dunno, maybe I’ll hang on to it. For a while.

Hey Canadians, this is a huge issue. This mine will pump out millions of gallons of sulphuric acid that will flow into Quetico Park, Rainy River, right up to Lake Winnipeg. It's 40km from the border. It could be Sudbury all over again for Canadian lakes. And our governments are doing nothing. read:

Doug Ford nixes idea of grocery surveillance pricing ban in Ontario Ontario Premier Doug Ford is nixing the idea of banning so-called surveillance pricing on groceries, as Manitoba has proposed.

What a surprise. Ford shows yet again he is perfectly fine with letting his corporate owners screw over the people of Ontario.

Why the AI backlash has turned violent And why it's probably only going to get worse from here.

Last week, a 20 year-old man threw a molotov cocktail at Sam Altman's mansion; two days later, people fired a gun at it. Earlier that week, someone fired gunshots into an city councilman's house who approved a data center.

Why the AI backlash has turned violent:

The lack of scientific literacy will destroy us all. I wonder if the people who designed the sign that says "H₂O₄U" even know what they have written.

Obligate faunivorous megatheropod size class patterns across the Jurassic-Cretaceous Periods Allosauroidea, Ceratosauria, Megalosauroidea, Megaraptora, and Tyrannosauroidea are five clades containing obligate faunivorous megatheropods. These clades included apex predators from the Early Jurassic until the end of the Cretaceous Period. Studying the timeline of median size class change for ceratosaurians, tyrannosauroids, and megaraptorans compared to the extinction of the incumbent apex predator clades, allosauroids and megalosauroids, is important regarding megatheropod guild structure. This study used the median size classes exhibited by these clades throughout the Jurassic and Cretaceous Periods, along with the relationship of the median number of missing size classes under different apex predatory regimes. We calculated size class medians for each clade during six discrete time bins. Statistical tests on the median size class data were run to identify potential significant differences and test if increases in median size class occurred after the Cretaceous Thermal Maximum (KTM). Statistical tests were run on the number of missing size classes for each type of apex predator regime to determine if previously proposed hypotheses may explain potential differences. Statistical differences were found between four pairs of clades and their respective median size classes. Median size class increased after the Cretaceous Thermal Maximum for tyrannosauroids and potentially megaraptorans, but increased before the Cretaceous Thermal Maximum for ceratosaurians and did not change afterwards. The median number of missing size classes was found to be higher in the abelisauroid, abelisauroid/megaraptoran, and tyrannosauroid ecosystems compared to allosauroid/megalosauroid ecosystems. The median number of missing size classes between allosauroid/megalosauroid environments and tyrannosauroid-dominated environments was found to be significantly different, with a higher median number of missing size classes in tyrannosauroid-dominated environments. The analysis provides support for hypotheses, such as intraclade niche partitioning or niche shifting, to explain the differences in the median number of missing size classes between abelisauroid, abelisauroid/megaraptoran, and tyrannosauroid ecosystems and allosauroid/megalosauroid ecosystems. This study implies a complex history regarding the timing of the increase in the median size class for clades that survived the Cretaceous Thermal Maximum, which requires further study.

The idea that high oxygen levels led to the appearance (and eventual disappearance) of giant insects in the Carboniferous has been weirdly difficult to kill, even though insects stayed quite big for quite some time afterward. This, hopefully, puts a bullet through it

The first non-mammalian synapsid embryo from the Triassic of South Africa Oviparity was likely the plesiomorphic reproductive condition for non-mammalian Synapsida, the stem-mammal group. Yet, despite nearly two centuries of research, no definitive fossil eggs of late Palaeozoic or early Mesozoic synapsids have been discovered. Here, three perinate specimens of the dicynodont genus Lystrosaurus from the Early Triassic of the South African Karoo Basin are examined using high-resolution CT and synchrotron scanning. One specimen, NMQR 3636, displays a tightly curled posture suggestive of an in ovo position and completely lacks tusks. Crucially, the lower jaw symphysis remains unfused—a developmental trait found only in pre-hatching embryos of modern birds and turtles. No calcified eggshell is preserved, so the egg might have been soft and leathery. The large size of the reconstructed egg suggests a precocial, non-milk-feeding developmental strategy. As a non-cynodont synapsid, Lystrosaurus offers a rare and valuable glimpse into reproductive biology far removed from the mammalian crown group. Unlike the more derived, mammal-like cynodont Kayentatherium, whose egg size aligns with lactation, Lystrosaurus anchors the plesiomorphic condition deep within Synapsida. Its reproductive strategy may have played a crucial role in its resilience and ecological dominance following the end-Permian mass extinction.

“We see a future where intelligence is a utility, like electricity or water, and people buy it from us on a meter,” said Altman, laying out an intensely dystopian future as just another business development. “One of the most important things in the future is that we make intelligence, to borrow an old phrase from the energy industry that didn’t quite work, ‘Too cheap to meter.’”

When I first heard what Altman had said, I was shocked and bewildered. How does someone even conceive of metering (and monetizing) intelligence if they’re not a tech billionaire with an intense antipathy toward humanity? It was clearly not something that would ever be achieved in practice. But it did hint at a much deeper issue with these AI tools, what they’re doing to our cognitive capacities, and the broader ideology underpinning the industry’s effort to force AI into every facet of our lives.

Altman made this declaration at an infrastructure summit hosted by BlackRock. It’s the latest in a long line of outrageous statements he’s made to try to justify the rollout of generative AI and the massive cost to power it.

Scientists invented a fake disease. AI told people it was real Bixonimania doesn’t exist except in a clutch of obviously bogus academic papers. So why did AI chatbots warn people about this fictional illness?

Bloody hell. Researchers invented a disease, published two fake papers to see if LLM’s would ingest them and kick them up as fact — and then it broke containment and all the major AI’s bought in. Information pollution.

Make ‘em dumb, sell ‘em smarts Sam Altman wants intelligence to be a utility that you pay him for

Sam Altman has a new plan to make money from generative AI: he wants intelligence to be treated like water or electricity — and we’ll all have to pay him for it.

His chatbots are degrading people’s ability to retain information and think critically. Now he wants to sell smarts back to us.

So, in those spaces where AI is viewed as a useful tool, the narrative is generally that it is what you use for the unimportant things so you can get onto what matters.

I’m not averse to that framing, because it allows the use of AI to communicate to me what something thinks is unimportant.

As AI Breathes Down Our Necks, It’s Time for a Luddite Renaissance Nineteenth-century textile workers longed to stay human in a machine age. So do we.

The Luddites were the good guys!

Technically skilled masters of their textile crafts, they opposed wealthy industrial speculators who forced workers (including children) to give up control over their future and toil in Blake’s “dark satanic mills.”

In this AI moment, we can learn a lot from them.

I think AI is poison to paleontology. I've seen it create fake citations in scientific papers. I've seen it create garbage art, stolen from talented artists.

Paleontology doesn't need AI.

The beautiful preservstion of trilobite compound eyes will never cease to amaze me. On this little 400ish million year old Phacops you can see all the little lenses - each one a rigid calcite mineral crystal! Together they had excellent 360° vision, perfect for finding lunch on the seafloor.
