Local groups initiated the effort after observing mass amphibian deaths. Wildlife cameras later captured over 2,200 ...

Deep below the thick ice of Greenland lies a labyrinth of tunnels that were once thought to be the safest place on Earth in case of a war. First created during the Cold War, Project Iceworm saw ...

The Tiltrotor Test Rig, a test bed developed by NASA to study advanced designs for rotor blades, is seen in the 40- by 80-foot test section of the National Full-Scale Aerodynamics Complex in ...

When the new wind tunnel opens in Virginia in 2025, the space agency's machine will be more than 100 feet tall. ... How epic wind tunnels on Earth make us better at flying through space.

Though the chance of finding micro-tunnels on Earth is likely small, they may be present in places around us, like the rocks, glass, and metal of buildings — particularly old buildings.

Stojkovic and his colleague calculated that if a very fast PBH with a mass of 2.2 x 10^19 pounds (that’s 22 followed by 18 zeros) shot through a solid object, it would leave behind a tunnel 0.1 ...

During downtime after the project, Potter reportedly read the fantasy novel “At the Earth’s Core,” which among other things is about an “iron mole” that tunnels hundreds of miles down.

There’s no shortage of work out there, either. China recently completed a 20-kilometer railway tunnel in the Longmen Mountains after a decade of construction. There’s the HS2 rail project in ...

For objects without a liquid core, PBHs might simply pass through and leave behind a straight tunnel, the study proposes. For example, a PBH with a mass of 10 22 grams — that’s a one with 22 zeros — ...
