Something happening in North Korea.
After all that hoo-ha about Stuxnet being an Israeli/US creation designed to take down Iranian nuclear sites, we really don't know any of that or much about its origin.
A scary and dangerous mess in Hungary. It's what could have happened in Sillamäe, although the mess would have spilled into the Baltic Sea, not the town. Fortunately, the Estonians stabilized that horribly engineered (probably not engineered at all) dam and constructed an engineered cover over the tailings. Now it's a port. One of the things I'm proud to have participated in. (h/t to Plutonium Page) Update: photos from Hungary.
