In 1957, the United States conducted its first underground nuclear test, known as Rainier, at the Nevada Test Site. The device was detonated inside a carved tunnel deep within the rock, marking a major shift from open-air tests to underground experiments that produced far less radioactive fallout. The explosion created a powerful seismic wave that scientists used to study how nuclear blasts behave beneath the earth. via: NNSANevada yt | History In Pictures

🚇🗺️ A London-based developer has created a live 3D map of the London Underground. The interactive map uses real-time TfL data to show trains moving across nine of the 11 Tube lines. Ben James said he thought people "enjoyed it much more" than he thought, and said "it's been really fun to see". #London #LondonNews #LondonLife #LondonUnderground #LondonTube | BBC London
