Zwei Milliarden für den Langzeitbetrieb: Gösgen-Chef fordert Hilfe vom Bund
Das AKW Gösgen könnte bis 2059 am Netz bleiben – dafür wären Investitionen von rund zwei Milliarden Franken nötig. Daran soll sich auch der Bund beteiligen.

Today, science became a target for Russia. My heart goes out to the heroes searching for people trapped inside Ukraine’s National Academy of Sciences. As well as to the families and loved ones of the victims of horrific attacks across the country.

I am sad to report that a formidable colleague, Ken Lane (Boston U), has died. Ken made many notable contributions, among them his work on the Cornell charmonium model, dynamical symmetry breaking in the form of extended technicolor, and supercollider physics. He shared the 2011 Sakurai Prize. RIP!

A bit of history of particle physics that takes an unexpected turn today. In 2003 the BaBar experiment at SLAC reported a particle decaying to a Ds meson and a neutral pion, with a mass of 2317 MeV. arxiv.org/abs/hep-ex/0...

An update @koppenburg.ch! A week and a half in, and the arXiv is humming with theoretical takes on LZ230616.
Chart showing cumulative arXiv preprints mentioning "LUX-ZEPLIN," by original submission date. Light blue curve begins in bottom left on October 7, 2013, the first preprint submission date, and curves to the top right to a count of 130 total preprints by July 27, 2026. A solid black diamond at coordinates (9/1/2026, 131) denotes the announcement date of LZ230613, the candidate dark matter detection event. From September 1, 2026, to September 10, 2026 inclusive, an additional 44 preprints mentioning LUX-ZEPLIN have been posted, nearly all of which are dark matter theory papers.

While the Higgs mechanism gives mass to particles that's only 1 to 2 % of your mass. The rest is due to the kinetic energy of quarks and the strong interaction in the protons and neutrons that make up everything.

Most of what makes Bluesky different is invisible from the feed! It runs on the AT Protocol, an open network that no single company fully controls, and that shapes everything here, from how blocks work to what happened when a state tried to restrict it. A few lesser-known facts: 🧵

Erwin Schrödinger not a paedophile after all(?). While googling Schrödinger I found this article by @jolauki.bsky.social (in its French version in my local newspaper) about how biographer Walter Moore invented Schrödingers "Lolita syndrome" based on incomplete reading of his memoirs.

Did you know that despite the claims that the Higgs Boson was the final puzzle piece of the Standard Model, there is another Standard Model particle that we have still never unambiguously observed? It isn't a quark or a gluon... So what is it?... Link: www.youtube.com/watch?v=srbC... ⚛️🧪
