We report the first calculation of light scattering on heavy dark matter (DM) particles: #DarkMatter, the substance that makes up most of the Universe, could potentially be detected as a red or blue light ‘fingerprint’, new research shows: https://www.york.ac.uk/news-and-events/news/2025/research/dark-matter-light-colour/
"The relationship between national identity and how people feel Scotland should be governed is, if anything, even bigger now than it was in 2015. In our latest survey, support for #ScottishIndependence is 60 points higher among those who say they are ‘Scottish, not British’ than it is among those who indicate they are wholly or mostly British"

"People notice that while AI can now write programs, design websites, etc, it still often makes mistakes or goes in a wrong direction, and then they somehow jump to the conclusion that AI will never be able to do these tasks at human levels, or will only have a minor impact. When just a few years ago, having AI do these things was complete science fiction!"

The venerable Risks Digest has not been published in a couple of months. Checking to see if this is an intentional break or not.
Now I expect many reading this to either be learning of Risks for the first time or realize they've forgotten about it. Old school.

"However, by 2015, support for independence stood at 52% among those on the left, compared with just 24% among those on the right – a difference of 28 points... In our most recent survey in 2024, those on the left were 34 points more likely than those on the right to say that Scotland should become an independent country"
