Happy accident yields a self-assembling quantum marvel

The findings unlock a path to harnessing ultra-fast magnetic materials and cleaner computer memory and hardware — enabling performance gains that could solve major energy bottlenecks facing modern data centers.

How scientific instruments reinforced distorted ideas about race

A new exhibit at Harvard’s Collection of Historical Scientific Instruments, opening Friday, probes how calipers and spirometers never simply recorded differences. They helped invent them.

 Analyzing ‘time capsules’ from the early solar system, delivered by meteorites

Harvard geoscientists reported that organic matter harvested from certain meteorites bears chemical traces of “primitive oxygen reservoirs” that have changed little since the birth of our solar system. The findings help trace the origins of organic matter that meteorites may have delivered to a young Earth, supplying the planet with ingredients essential for life.

How to build an evolutionary trap for viruses

Two Harvard scientists describe a way to engineer the evolutionary landscape that viruses experience, pushing them away from dangerous variants and into evolutionary dead ends.

Mapping source of volcanic activity deep within the Earth

Upon moving to Cambridge, geophysicist Xiyuan Bao often relied on navigation software to find his way through the unfamiliar network of roads. He realized the same technology could help him find something else: a solution to a mystery deep within the Earth.
