What the electron’s near-perfect roundness means for new physics
The electron remains stubbornly round, meaning we may need to build beyond the Large Hadron Collider to find physics outside of the standard model.

The Neil Armstrong biopic ‘First Man’ captures early spaceflight’s terror
At a time when NASA is considering how to return astronauts to the moon, ‘First Man’ is a sobering reminder of how risky the first giant leap was.
