Improving measurements by reducing quantum noise

If you want to measure something very precisely, such as slight variations of a length, then you are very likely to use light waves. However, many effects, such as variations of gravity, or surface forces, can only be measured ...

Neutrons uncover new density waves in fermion liquids

Scientists working at the Institut Laue-Langevin, one of the world's leading centres for neutron science, have carried out the first investigation of two-dimensional fermion liquids using neutron scattering, and discovered ...

Neutrons reveal key to extraordinary heat transport

Warming a crystal of the mineral fresnoite, Oak Ridge National Laboratory scientists discovered that excitations called phasons carried heat three times farther and faster than phonons, the excitations that usually carry ...

Dawn spacecraft spirals down to lowest orbit

(PhysOrg.com) -- NASA's Dawn spacecraft successfully maneuvered into its closest orbit around the giant asteroid Vesta today, beginning a new phase of science observations. The spacecraft is now circling Vesta at an altitude ...

Bringing neutron stars down to Earth

Imagine taking all of the water in Lake Michigan—more than a quadrillion gallons—and squeezing it into a 4-gallon bucket, the kind you'd find at a hardware store.
