A clock based on just a single atom — the simplest clock yet — has now been devised, researchers say. This new device to measure time could help lead to a radically new way to define mass as well, ...

In the quantum world, making the simple atom behave is one thing, but making the more complex molecule behave is another story. Now scientists have figured out an elegant way to stop a molecule from ...

Forbes contributors publish independent expert analyses and insights. I write about physics, science, academia, and pop culture. These days, everybody learns in grade school that an atom looks a bit ...

A quantum dot is usually charged by inserting electrons. But electrons can also be removed from a neutral dot. Unexpectedly, positively charged dots are different from highly charged negative ones, ...

Using ultra-high-precision laser spectroscopy on a simple molecule, a group of physicists has measured the wave-like vibration of atomic nuclei with an unprecedented level of precision. The physicists ...
