This week in science: Webb traces the most distant known fast radio burst, IceCube earns the 2026 Physics Nobel, nuclear clocks begin ticking, Artemis II sees lunar impacts, and Hubble finds a possible second-generation planet.

The 2026 Physics Nobel recognizes Francis Halzen’s decisive contributions to IceCube—the Antarctic observatory that transformed a cubic kilometer of ice into a new way to study the universe.

A peer-reviewed model explores how a compact extra dimension could naturally create resonant dark matter and testable experimental signals.
