It might not look like much — a plastic box that fits in the hand, with tiny tubes jutting out the top and bottom. Too simple to be cutting edge. Too humble to save so many lives.

But for 20 years, researchers in Robert Prud’homme’s lab have fine-tuned this little box that has revolutionized drug manufacturing, enabling everything…

Two years ago, molecular biologist Zemer Gitai and his research group announced that they had discovered an antibiotic that simultaneously pierced through a disease's defenses while poisoning it from within, like a poison-tipped arrow. And better yet, it was not susceptible to antibiotic resistance.

Discovering the “poisoned arrow"…

Princeton chemists find the surprisingly simple way mammals keep their bloodstream in balance

Chemists tend to think of the human body as operating out of a sense-and-respond paradigm. For example, you eat sugar, the pancreas senses the intake, and it responds by releasing the hormone insulin to keep your glucose levels in check.

Scientists have long wondered whether there is a similar regulatory strategy for clearing other…

During animal development, specific genes become active in different cells at exact times in order to produce all the tissues and structures of the body. This exquisite genetic choreography is made possible by multiple layers of organization built into organisms’ DNA.

The ability to edit the genome by altering the DNA sequence inside a living cell is powerful for research and holds enormous promise for the treatment of diseases. However, existing genome editing technologies frequently result in unwanted mutations or can fail to introduce any changes at all. These problems have kept the field from reaching…
