Read moreFast or superfast water transport with carbon nanotubes?
There were high hopes of using carbon nanotubes, particularly for ultra-fast water transport to desalinate seawater. However, a simulation now reveals that these ultra-fast transport rates might have not been properly grounded after all. Researchers who work with experiments and computer models have been at odds over the capabilities and governing physics of the material ever since.

Read moreScientists build record-setting metamaterial flat lens
For the first time, scientists working at the National Institute of Standards and Technology (NIST) 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.

Read moreA quantum simulator for magnetic materials
Physicists understand perfectly well why a fridge magnet sticks to certain metallic surfaces. But there are more exotic forms of magnetism whose properties remain unclear, despite decades of intense research. An important step towards filling these gaps comes now from Tilman Esslinger and his group at the Department of Physics. The team has developed a new kind of device that uses laser beams and atoms to emulate magnetic materials.
