    Turning magnetic resonance inside out

    A new method of manipulating magnetic signals makes it possible to gather useful information about a chemical sample—or perhaps one day a person—without often-claustrophobic confinement inside a magnetic coil.

    Antimatter mystery transcends new data

    The discovery of a disparity in decays of subatomic particles known as B mesons and anti-B mesons sheds light on how matter and antimatter differ but deepens the mystery of why matter predominates in the universe today.

    Physics Bedrock Cracks, Sun Shines In

    The first data from a new Canadian detector of particles called neutrinos not only resolve a 30-year-old puzzle about how the sun works, but also revise estimates of mysterious "dark" matter in the universe and strengthen a key challenge to the prevailing theory of particle physics.
