Changing an atom in a molecule using light? This South Korean scientific breakthrough could revolutionize the pharmaceutical industry. Replacing a single atom in a molecule without altering the others ...

An animation shows how attaching molecular anvils (gray cages) to softer molecules (red and yellow balls) distributes the pressure from a bigger diamond anvil unevenly, so chemical bonds bend and ...

Physicists at MIT have developed a new way to probe inside an atom's nucleus, using the atom's own electrons as "messengers" within a molecule. Typically, experiments to probe the inside of atomic ...

For all its possibilities, nature tends to replay one particular scene over and over again: the confrontation between matter and light. It stages the scene in a practically infinite number of ways, ...

Physicists have discovered a unique new molecule that could lead to many useful applications, and show how chemical reactions can be studied on a microscopic scale using tools of physics. UCLA ...

And now to another in our Brief But Spectacular series. Tonight, we hear from Janet Iwasa, an assistant professor of biochemistry at the University of Utah, who is trying to increase the public's ...

A molecule with a knack for picking up and delivering atoms may prove a useful tool for atomic-scale construction. Scientists in France and Germany who created and tested the molecule say that it and ...

For some time now, researchers have been managing to craft ever-smaller devices, though they're approaching the problem from two directions. Some researchers are etching small features into chips to ...

Call it the big chill. Laser cooling has tackled its biggest molecule yet, bringing the temperature of a three-atom molecule to within a thousandth of a kelvin of absolute zero for the first time. The ...

This image depicts the radium atom’s pear-shaped nucleus of protons and neutrons in the center, surrounded by a cloud of electrons (yellow), and an electron (yellow ball with arrow) that has a ...
