Researchers have developed a powerful computational framework that shows how carefully optimized nanotube shapes can amplify ...

NASA scientists have discovered a third global energy field around Earth. Known as the ambipolar electric field, this force drives charged particles into space above the poles. Two major global energy ...

Earth’s magnetic field has long been framed as a planetary force field, a protective bubble that keeps the worst of the Sun’s radiation at bay. Increasingly, though, scientists are finding that this ...

This remarkable miniature rotorcraft is so lightweight and efficient that it can lift its own mass given nothing but sunlight. The entire thing weighs about as much as four paperclips, and it can fly ...
