This is why we need 100% renewables:

There are a hundred more important things to say, and I tried to say some of them in my essay for "Thinking About...", but: invading a country for oil is also just atavistic at this point. Even if it worked, which it won’t, it still wouldn’t work.

Finger weg vom 2017 Renault Zoe! Nach 55k km war der Motor platt. Sonst auch sehr schlecht gebaut. Mein VW Diesel hat hingen 225k km und nie ein Problem. Kann also auch daneben gehen. Generell mag ich EVs aber man ist jetzt auf der Hut bezgl des Herstellers.

His children from his German ex-wife are British-German and presumably speak both? The level of dishonesty is quite remarkable.

Stephen Flynn criticises Nigel Farage from attacking children who speak more than one language #BBCQT

"A man who aspires to be PM of these isle would pick a fight with school kids, would hold school kids up as an object to beat, absolutely repulses me and it should repulse all of you as well"

The Economic Impact of Brexit Other

Still reeling from the Stanford report on Brexit. Reduced GDP by up to 8% and investment by as much as 18%. The UK Treasury would have Β£40 billion more each year if Britain had remained in the EU. Devastating self-immolation.

The role (and esp. mechanism) of PGR5 remain elusive and we needed new tools to get to the bottom of it. Biosensors have so much potential to gain a deeper understanding of cellular bioenergetics πŸ”¬πŸŒ±βš‘οΈ

So happy this is out as a preprint (for) now. Since measuring ATP is tricky, we used ATP biosensors in collab with @schwarzlanderlab.bsky.social to show that in chloroplasts without PGR5, NPQ and pmf are diminished, yet ATP levels unchanged. Balancing ATP/NADPH must be achieved by different means.

Our new preprint πŸš¨πŸŒ±β˜€οΈon flourescent biosensing of ATP levels in chloroplasts in vivo shows disequilibrium between proton motive force and ATP levels. We show PGR5 dependent cyclic electron transfer does not augment ATP/NADPH ratios @gustaf23.bsky.social πŸ™Œ

Today, Germany remembers the November pogroms of 1938.

87 years ago, Jews were targeted in a wave of orchestrated violence in Germany. Jewish shops and synagogues were destroyed. Many Jews were murdered.

These acts of terror paved the way for the Holocaust.

It took decades for the work of Mary Brunkow, Fred Ramsdell, and Shimon Sakaguchiβ€”the winners of this year's Nobel Prize in Medicine or Physiologyβ€”to have clinical relevance. That and more of the best in @science.org and science in this edition of #ScienceAdviser: www.science.org/content/arti... πŸ§ͺ

We mourn the passing of our Editor-in-Chief Steve Long.

His vision to establish one of the first journals dedicated to Global Change over 30 years ago was truly ahead of its time. Through GCB, researchers have demonstrated that biology and ecosystems are not simply victims of global change..

A very mistaken list of the last 12 presidents of the United States and their years in office produced by the Ph.D level scholar known as ChatGPT-5. Includes John F. Katwady, president 1991-1968; George W. bush, president 220Z-1999), and Bill Christen, president 1999-2001

I've seen this on Bluesky and had to try it myself. The image below was the response to the prompt: "Show me a diagram of the US presidents since Herbert Hoover, with their names and years in office under their photos" Bravo, OpenAI, bravo.
