Meanwhile in Ukraine @meanwhileua.bsky.social · 01/03/2026
A rock band can’t stop a missile. But it can keep Ukraine in the world’s ears. U2 released “Yours Eternally” with Ukraine’s Antytila and Ed Sheeran, alongside a short film by Ukrainian filmmaker Illia Mykhailus using real frontline footage. Attention is a form of support.

I share the sad news that Prof. David H. Waldeck passed away after a battle with cancer. Dave was an extraordinarily creative scientist, a devoted educator, and to all of us a friend, mentor, and leader. He will be deeply missed #chemsky #chemchat

Today marks four years since the start of Russia’s unjustified, full-scale invasion of Ukraine. This morning, I spoke with members of the Coalition of the Willing to reinforce our support for a just and lasting peace.

Physics isn’t immune to the replication crisis. Sergey Frolov sees a way forward.
A critic of what he says are unjustifiably bold claims in his field, the Pitt physicist advocates for more data sharing in a new paper in Science.

Here is a temperature map (in celsius) of the USA today, during what is being called the "Big Freeze". Ukraine was colder than this basically every day from Jan 5-23. And thanks to the USA helping Putin, the country was starved of heat and power.

My view they should be written so that you don't need to read them. Write what readers need to know in short blocks and name the blocks so the info is easy to find.
