Get in losers, we're reinventing Narrow AI
Excerpt reads: "Smaller models fine-tuned for industries such as law and finance - or even individual companies - could make AI cheaper to run. Trained on specialist or proprietary data, they may require less computing power while outperforming general-purpose frontier models on narrow tasks."

I'm an associate editor at ICRA and my humble conclusions so far are: 1. We should ban Claude ("It's *B*, not A") 2. We should stop the made-up acronyms, names and catchy titles. It was fun in 2012, not anymore.

Just a reminder that people don’t always realize they were raped in the immediate aftermath. It can take hours, days, months, and even years to realize you were raped, and it doesn’t make it any less true. There are many kinds of responses, including fawning and trying to appease your rapist

A suggested statement for Andy Burnham.
‘The British public decided in the 1930s that they would not tolerate black-shirted militias marching through their streets. They would cherish robust political argument; they would not accept thuggery and intimidation. When Oswald Mosley led his Blackshirts to Cable Street, local people turned them back. A new law – introduced by a Liberal, backed by Labour and carried by a Conservative majority – banned private militias, political uniforms and ‘the use or display of physical force in promoting any political object’. The British people are as determined today as in the 1930s that they will not accept the methods of Mussolini and the Munich Beer Hall. This government will uphold the law and defend the traditions of British democracy’.

Operational biological sex definitions applied to hummingbirds (Bleiweiss 1992; Bleiweiss 1999; Bleiweiss 2001; Diamant et al. 2021; Falk et al. 2022; Falk et al. 2021) where sex is operationally defined by binary plumage phenotypes in the field. Each row depicts a wild individual hummingbird with morphological traits (beak length, plumage coloration), behavioural traits (territoriality) and their unobserved gamete type. This example illustrates how the same individual can be operationally defined as one sex in the field (based on external phenotypes) but classified as a different sex based on their gametes (which cannot be easily observed in the field), highlighting how definitional choices shape scientific reporting of sex.

UK waters hit with extreme heatwave as global sea temperatures reach record levels
Experts warn that some marine species are at risk of ‘mass mortality events’ in ever-warming oceans UK waters are being hit with an “extreme” marine heatwave, the Met Office has said, as scientists warn the high ocean temperatures globally could result in “mass-mortality events” for some species. The forecasters said these elevated temperatures have developed rapidly because of last month’s heat dome, during which most of Europe sweltered in its worst ever heatwave that scientists said would have been impossible without the climate crisis.
