Hubble reveals a stunning twist in how the universe emerged from darkness
Hubble data on starburst galaxies show faster supernova winds let less ionizing light escape, opposite to a leading idea about reionization.

Radio waves delivered through a scanning tunneling microscope flipped the nuclear spin of a single atom, an effect simple theory says should fail.

A long-lived heavy right-handed neutrino may have dominated the early universe and shaped the matter-antimatter imbalance, possibly leaving gravitational-wave traces.

A theoretical analysis finds a black hole could fission into two only when its spin is extreme, the reverse of the usual merger story.

Six-layer rhombohedral graphene shows insulating states, superconductivity and two kinds of orbital magnetism where electrons and holes coexist.
