The better to see you with: Scientists build record-setting metamaterial flat lens
For the first time, scientists working at the National Institute of Standards and Technology have demonstrated a new type of lens that bends and focuses ultraviolet (UV) light in such an unusual way that it can create ghostly, 3D images of objects that float in free space. The easy-to-build lens could lead to improved photolithography, nanoscale manipulation and manufacturing, and even high-resolution three-dimensional imaging, as well as a number of as-yet-unimagined applications in a diverse range of fields.

Research effort deep underground could sort out cosmic-scale mysteries
(Phys.org) —The Department of Energy's Oak Ridge National Laboratory has begun delivery of germanium-76 detectors to an underground laboratory in South Dakota in a team research effort that might explain the puzzling imbalance between matter and antimatter generated by the Big Bang.

Physicists suggest possible existence of other kinds of dark matter
(Phys.org) —A team of Harvard University physicists has proposed the possible existence of a type of dark matter not described by current physics models. In their paper published in the journal Physical Review Letters, the team suggests it's possible that not all dark matter is cold and collision-less.

New family of tiny crystals glow bright in LED lights
(Phys.org) —Minuscule crystals that glow different colors may be the missing ingredient for white LED lighting that illuminates homes and offices as effectively as natural sunlight.

Observation of skyrmions (magnetic vortex structures) in a ferromagnet with centrosymmetry
Researchers using Lorentz electron microscopy have shown that magnetic skyrmions are spontaneously formed as nanomagnetic clusters in a ferromagnetic manganese oxide with centrosymmetry.
