A Polish museum has invited Robert De Niro to view their portrait of a local 17th-century nobleman who many have noted looks remarkably similar to the Hollywood star, right down to the moles on their cheeks.

Actually, Trump is threatening to do something that Biden never did. The threat is about SECONDARY sanctions on Russia’s trading partners, not just more primary sanctions on Russia.
This is a long overdue move.
Seems Trump is finally coming around to a correct strategy. 🤞

How to sound tough but do nothing: Impose tariffs on a country where we already impose sanctions.
A 100% tariff on almost nothing will do almost nothing.

Meet Shraik, the wild kestrel who attacked a Russian drone mid-flight.
Wounded but alive, he was rescued by Ukrainian soldiers & underwent surgery.
Recovery will be long. His rescuers paid for everything. He is one of them now.
Now he rests. One day, he’ll fly again—over free Ukrainian skies.

It's wild to me that in 2025 there are academics advising their students to never use AI.
6. NEVER USE IT YOURSELF. EVER! The most common issue I hear from students is that some of their lecturers use ChatGPT for feedback, syllabus creation, etc., so why shouldn't they? Of course I'm not the boss of you, but as soon as you use it for ANYTHING, you're giving students implicit permission.
