Fascinating and deeply satisfying resolution to why adenovirus-based vaccines produced blood clots in 1 out of 200,000 people.
Two factors interacted:
a mutation in an antibody gene + weak similarities between a viral protein & a human blood-clotting protein = induced clotting cascade.

Five years after the rollout of Covid-19 vaccines started, it seems the mystery of why the Astra-Zeneca and J&J vaccines led to a rare but deadly side effect of unusual blood clots and bleeding has finally been solved.
It's a fascinating case of molecular mimicry that may help make vaccine safer.🧪

Ukrainian skeleton racer Vladyslav Heraskevych was banned from using a helmet at the 2026 Olympics that depicted fallen Ukrainian athletes. At the same time, an Italian snowboarder competed wearing a helmet with the Russian flag - which is prohibited and "there was no reaction to this."

Ukrainians will soon be required to register their Starlink terminals to be added to a whitelist, after which only verified and registered terminals will be allowed to operate in the country.
Russian drones use Starlink, but Ukraine has plan to block their Internet access
Defense chief: "No Ukrainians have been killed by Russian drones using Starlink."

Almost 4 years into this full scale war and Russian tankers are now using NATO territorial waters in order to avoid being attacked by Ukrainian drones.
You read that correctly. Russians hiding behind NATO, because they lost control of the Black Sea.

The actual story is that a family of American citizens trying to evacuate from a neighborhood that ICE had made unsafe, and then ICE tossed munitions into the car, causing three kids to be hospitalized and a six month old to stop breathing. DHS called the family “radical agitators”

🧵 Thread on beautiful data centers:
MareNostrum 4 (Barcelona SCC): Often called "the most beautiful data center in the world," this facility is housed inside the Torre Girona Chapel, a deconsecrated 19th-century church.
When fully installed, it will have a peak performance of 13.9 Petaflops.

No signs of an end to rapid gains in AI ability at ever-decreasing costs (which is a log scale) yet. I have to update this monthly or more frequently at this point.
All AI benchmarks are flawed, but GPQA Diamond has been a pretty good one, though likely close to being maxed out.
