When drugmakers want to improve on compounds they have already created, they can replace a carbon atom with a nitrogen atom. While effective, the techniques they use to perform this chemical swap, known as skeletal editing, have some downsides. For example, older approaches often

When drugmakers want to improve on compounds they have already created, they can replace a carbon atom with a nitrogen atom. While effective, the techniques they use to perform this chemical swap, known as skeletal editing, have some downsides. For example, older approaches often require harsh chemicals or only work on specific types of molecules.

A quantum prediction from 1931 just came to life

Nearly a century after physicist Hans Bethe predicted them, scientists have created and directly observed unusual quantum states known as “Bethe strings” in an ultracold gas. By cooling cesium atoms to near absolute zero and trapping them in thousands of tiny one-dimensional tube
