Today, the University launched one of the world’s first Ph.D. programs in the subject of quantum science and engineering.

Researchers at Harvard have designed new, highly selective tools that can add or remove sugars from a protein with no off-target effects, to examine exactly what the sugars are doing and engineer them into new treatments for “undruggable” proteins.

Odontoblasts have a newly discovered function: sensing cold, which can trigger pain in teeth. But scientists have also found a way to block the pathway to cold-sensitive teeth.
