Why did they form at that time? Astronomers know from observing distant exploding stars that the size of the universe has ...

What color is an atom? Since atoms are smaller than the wavelength of visible light, we can’t see them directly - but they ...

Physicists at the Massachusetts Institute of Technology (MIT) have made a groundbreaking discovery, developing a tabletop ...

Getting atoms to do what you want isn’t easy — but it’s at the heart of a lot of ground-breaking research in physics. Creating and controlling the behavior of new forms of matter is of particular ...

If you think of a single atom as a grain of sand, then a wavelength of visible light—which is a thousand times larger than ...

Scientists used a fast laser to wiggle atoms, temporarily altering material behavior, a step toward smaller, more efficient electronics like smartphones. (Nanowerk News) Researchers at Michigan State ...

Imagine a knot so small that it can’t be seen with the naked eye. Then think even smaller. Chemists have tied together just 54 atoms to form the smallest molecular knot yet. Described January 2 in ...
