No jasně. I tak se dneska někteří ošklíbají i nad (druhdy běžně používaným) studentstvem.

I must admit I've become more and more trusting towards language models, I use them for coding help and as a sounding board to think about complex problems. They seem to work pretty well.

Until you ask them to make a list of about 30 items from a simple webpage and they make a third of them up...

It’s the renewables, stupid.

10 days of war have cost our taxpayers an additional €3 billion in fossil fuel imports.

As long as Europe depends on imported fossil fuels, our security & our energy bills remain hostage to geopolitical chaos.

Europe must invest in independence, not dependency. ⚡🌍

Vlastně si říkám, jestli dneska ještě vůbec někdo hrozí komunismem, jestli se už Overtonovo okýnko autodominance nevyrolovalo tak daleko, že už její kritika prostě ani nedává smysl a nevyžaduje protiargumenty...

Ribosome transfer via tunnelling nanotubes rescues protein synthesis in pancreatic cancer cells - Cell Communication and Signaling Cell Communication and Signaling - Pancreatic ductal adenocarcinoma (PDAC) is considered as one of the deadliest types of cancer. Tunnelling nanotubes (TNTs) are thin, membranous, intercellular...

Our paper (with @stanam.bsky.social and others) reporting the discovery of intercellular ribosomal transport and it capacity to modulate protein synthesis in cancer cells is published! It was a bit of a journey to find a home for this so very happy it's out! 🧪

One of the few things imo that we should just outright make illegal. Sunbeds kill people, and usually after costing the state enormous sums to prolong their lives. Completely needlessly. People can not comprehend the risks.

Statistical Rethinking Lecture A10 - Hidden Confounds & Sensitivity Analysis YouTube video by Richard McElreath

Here we go again: Lecture A10 of Stat Rethinking 2026 - Unmeasured confounds, confounded mediation analysis, collider bias (again), masked discrimination, sensitivity analysis and the importance of making strong assumptions, how to defend yourself against a hostile scientific literature.

Just read the abstract 🫠 via Alexander Magazinov. I don't believe he is on Bluesky.

Je to ovšem podmínka nutná, nikoli dostačující.

Pollen analysis indicates 9,000-year-old Shaman had a floral burial New scientific research has shed fresh light on one of Central Europe’s most remarkable archaeological discoveries — the 9,000-year-old grave of the so-called “Shaman of Bad Dürrenberg” in Germany. - ...

Shift in the Gulf Stream could signal ocean current collapse Models show that as the Atlantic Meridional Overturning Circulation gets weaker, the Gulf Stream will drift northwards. There are signs that this is already happening, and a more abrupt shift could wa...

A gradual northward shift in the Gulf Stream has provided more evidence that the system of currents keeping Europe warm is weakening. And modelling suggests that abrupt shift in the Gulf Stream could signal an imminent, catastrophic collapse in the ocean current.

Statistical Rethinking Lecture B09 - Generalized Linear Madness YouTube video by Richard McElreath

Lecture B09 of Stat Rethinking 2026: Generalized Linear Madness. Two examples of analyses that build up from scientific models first. #1 allometry predicts weight from height with ZERO parameters. #2 Vibrant ODEs for time series instead of cold dead lag models. Fully coded and animated with love.

You’re welcome. Happy day! 😆

For some time I used to mix them up in English, now I know the reason!

Fakt nechci, aby Ádvojka zanikla. Nic srovnatelně aktuálního, obzory rozšiřujícího a kvalitně udělaného u nás není a ta obtýdenní zásilka by mi fakt chyběla. Předplácím i přispěju.

Krásný, Arane!

This is not my image, nor was it my camera. My hats off to whoever took this beautiful picture. It shows that life will allow more than one species to benefit from one thing at once. Even Bees and Hummingbirds can share water or nectar.

Á, už tu máme naše RFK jr...

Ah, yes, the invaluable wisdom of the markets.
