No one can control the weather, but certain clouds can be deliberately triggered to release rain or snow. The process, known as cloud seeding, typically involves dispersing small silver iodide ...

MIT researchers have devised a new molecular technique that lets electrons probe inside atomic nuclei, replacing massive particle accelerators with a tabletop setup. By studying radium monofluoride, ...

Bose-Einstein condensates (BECs) are fascinating states of matter that emerge when atoms or molecules are cooled to extremely ...

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 ...

The first “atoms” in the universe were not atoms at all—they were just nuclei that had not found electrons yet. The simplest nucleus, that of common hydrogen, is a bare proton with no frills. When the ...

Just about anybody who played hide-and-seek as a kid remembers counting, with eyes (presumably) covered, in units of one-one-thousand. “One-one-thousand. Two-one-thousand. Three-one-thousand.” It’s ...

Astronomers used the James Webb Telescope to detect complex carbon molecules frozen around a young star, ST6, beyond our ...

IT may be doubted whether, fifty years ago, chemists and physicists believed very deeply in the actual reality of the molecules and atoms, which they used as convenient and simplifying conceptions to ...
