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 ...

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, ...

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 ...

If a picture is worth a thousand words, an animation could be worth countless more when it comes to the intricate molecular processes that scientists have spent decades trying to unravel and ...

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 ...
