    Window Opens into Strange Nuclei

    By creating peculiar atomic nuclei that contain not just protons and neutrons but also pairs of rare nuclear particles with so-called strange quarks inside, researchers are shedding new light on the fundamental structure of matter and how it behaves under extreme conditions, as in neutron stars.

    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.
