This Impossible Tunnel Put Together Like Lego Bricks Sticks Together with No Support

Yeah, I’m not ashamed to admit this: I feel slightly less comfortable when I’m under a tunnel than when I’m not. It’s not that I think that the tunnel will collapse on me, but it’s because I know the sky definitely won’t. This tunnel would put my fear into overdrive, because it has no permanent support and looks like it would collapse. In fact, the entire construction process looks like piecing together Lego bricks, and yet it can support so much weight. Read More >>

These Enormous Caverns Below NYC are Starting to Look Like Train Tunnels

It's been several months since we last checked in with New York City's perennially delayed, incredibly expensive infrastructural wonder: The East Side Access project, a plan to build a new station beneath Grand Central station that will connect Manhattan and Queens. Deep below the city, work continues—and now, the MTA has given us an update. Read More >>

Ancient Worms May Have Saved Life on Earth 530 Million Years Ago

About 2.5 billion years ago, microbes began making a poison that would cause one of the largest mass extinctions on Earth. The few organisms that could handle this poison flourished, going on to become our ancestors. The poison? It was oxygen. It's a wonder that oxygen levels didn't keep rising until Earth became uninhabitable, though, and a new study suggests we have an ancient worm tunnelling through the sea floor to thank. Read More >>

The Last Trace of Humans on Earth Will Be the Holes We Dug

When most of us think of what humans will leave behind when we go, we imagine skeleton buildings or toxic landfills. But according to some geologists, the longest-lasting impact we'll have on Earth is actually beneath our feet—in the form millions of tunnels, deep boreholes, and mines. Read More >>
