Early scientific theories—such as those explaining basic phenomena like gravity, burning, and the movement of molecules in ...

Using lasers, quantum sensors, and ultra-precise instruments, researchers can now detect forces once thought undetectable.

NASA’s Magnetospheric Multiscale Mission has uncovered surprising behavior of pickup ions drifting through the solar wind ...

Experiments reveal that when slabs of salty ice are strained, electricity is generated, though practical uses are still a long way off.

For centuries, people believed ice was slippery because pressure and friction melted a thin film of water. But new research from Saarland University reveals that this long-standing explanation is ...

The force of a spring (F) is directly proportional to the length (x). This means the more you stretch a spring out, the more it wants to snap back in place. Even though “K” is a constant in this ...

When a droplet of liquid the size of a grain of icing sugar hits a water-repelling surface, like plastics or certain plant ...

At a busy street crossing, people wait for the signal to change. When one person steps out first, others soon follow.
