When our warriors drove Russia out of Bucha, Irpin, Borodyanka, the entire Kyiv, Sumy, and Chernihiv regions, everyone could see that these were victories not only for Ukrainian courage and weapons, but also for human morality. May the entire world never forget the cost of this

Jon Stewart checks in on the war in Gaza and examines how America's "values" stack up against its support of Israel

A good law of history is that if you ever find yourself opposing a student movement while siding with the ruling class, you are wrong. Every single time. In every era. No matter the issue.

Let’s say we found evidence of any gov executing men ,women and children with hands zip tied behind them - being discovered in mass graves . Would it matter who they were ? What religion they said excused such atrocities - or what their ideological rationale was ? Of course

Student protesters were right about segregation in the early '60s, right about Vietnam in the late '60s, right about apartheid in the '80s, right about Iraq in 2003, and right about wealth inequality in 2011. Seems generally bad to side against student movements.

It was #fluorescencefriday yesterday 😌

In my view, being a PI isn't just about driving research forward—it's about creating real opportunities for the PhD students and postdocs in my lab. Their growth is as important to me as the science itself. #Mentorship #ResearchLeadership #PhDLife

🎉 Exciting news! Our 2nd-year PhD student Adam has just published his first paper! 📝 In it, we reveal that in alloyed Ag-In-Zn-S #QuantumDots, the photoluminescence mechanism is not linked to donor-acceptor-pair transitions. Great work, Adam! 🔬✨ See tinyurl.com/7kx4jhyu

Wittgenstein taught us that language isn't private—it works because it's shared and understood. Let's ensure the precision and clarity of scientific language by grounding it in well-established texts, not just the latest papers. #Read_Old_Papers

Former President of Poland Lech Wałęsa wrote the following letter to Donald Trump: 1/n

While you’re enjoying your weekend spring walk or Easter breakfast with family and friends, spare a minute and think of the children being shot, at the very same moment, in Ukraine, Gaza, Sudan.

Man, what a day to be in Ukraine. This country has proven again and again that the most powerful metric of any nation’s military strength is the will and dignity of free people fighting for a just and noble cause.
