Black branes are higher dimension #BlackHoles that have hydrodynamic properties. The Holographic Principle means these branes ≈ lower dimension #QFT fluids. The absorption cross-section of low energy #Gravitons by the brane is then proportional to ideal fluid viscosity. #Science #Physics #Gravity 🧪⚛️

The question isn’t IF climate change is making extreme weather worse—it’s how much.
Science can put a number on how many more homes flood, how much more rain a hurricane dumps, how much larger wildfires grow--and how much worse it will get if we don't act now.

Major test case for new geothermal technology launches in small German town
Residents in the German town of Geretsried have long wanted to run their buildings with clean heat and electricity from geothermal energy rather than fossil fuels.

On Friday night, HHS ordered CDC to take down all flu vaccine campaign materials from its website. Materials are starting to come down.
For example, a campaign explaining that flu shot can reduce flu severity from "wild to mild" is now offline. Left image is from Friday, right is now

I struggle to express just how *weird* Vance’s #MSC2025 speech was. This is a transatlantic security conference, happening while there is a war in Europe, and the US is announcing a partial withdrawal from European security. And the US VP speaks about (alleged) threats to free speech in Europe??

Based on peer-reviewed modeling, this report says that climate change -- via rising insurance prices & shifting consumer preferences -- is going to wipe out $1.47 trillion in US net property value.
I'm bad at budgeting. Is $1.47 trillion a lot?

Romania is diverse.
Romania has helped and is helping Ukraine a lot. It often helped silently, without any fuss. From the very first days, Romania opened its borders to our refugees and helped to transport equipment.
Romanian volunteers have fought and are still fighting in Ukraine.
