See the massive "bending" tunnel machine digging Sydney's Western Harbour Tunnel. It's a record-breaking feat of engineering.

China finished a tunnel 89 meters under the Yangtze. Bullet trains will soon cross at 217 mph without slowing down.

China is racing to build a self-sufficient artificial intelligence stack, from cutting edge chips to nationwide deployment, and its leaders now treat that effort with the urgency of a wartime program.

China has quietly built a machine that bends one of the most stubborn limits in physics research: gravity itself. By pushing hypergravity to levels roughly half again higher than the previous world ...
