    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.

    Stretching and twisting a bright idea

    A new, stretchy type of liquid-crystal component makes it possible to change a laser's color by simply pulling on the membrane—a much easier, cheaper means of adjustment than that used for today's complex and expensive tunable lasers.

    In a squeeze, nitrogen gets chunky

    Remarkable already for being a semiconductor and, perhaps, an explosive, a new, solid form of nitrogen made by crushing the ordinary gas to the highest pressures ever also stands out because it continues to survive when the pressure is released.

    Electrons trip on tiny semiconductor steps

    A first glimpse of how a semiconductor's surface alters electrons' magnetic fields, or spins, suggests that tiny steps in the surfaces are tripping up efforts to create so-called spintronics circuits from semiconductors.
