(Phys.org) —Holograms have attracted wide attention for their ability to produce a realistic 3D image of an object by recording the object's light field and later reconstructing the light field on a 2D surface. Now researchers ...
(Phys.org) —Two researchers from Queensland University in Australia have developed a way to describe polarizing objects in a way that can be visualized by the human eye. In their paper published in Proceedings of the Royal ...
(Phys.org) —There is, so to speak, uncertainty about uncertainty – that is, over the interpretation of how Heisenberg's uncertainty principle describes the extent of disturbance to one observable when measuring another. ...
Using bundles of vertical zinc oxide nanowires, researchers have fabricated arrays of piezotronic transistors capable of converting mechanical motion directly into electronic controlling signals. The arrays could help give ...
Fraunhofer Heinrich Hertz Institute (HHI) and Fujitsu Laboratories Ltd. have achieved locally distributed wavelength-division multiplexing with exactly defined frequency spacing. Four Nyquist-shaped 25-GBd quadrature phase-shift ...
Animals consist of many distinct cell types, all of which originate during development from a single cell: the fertilized egg. To generate this vast cellular diversity, the egg and its descendants must divide unevenly to ...
NASA has mobilized its remote-sensing assets to help assess the spread and impact of the Deepwater Horizon BP oil spill in the Gulf of Mexico at the request of U.S. disaster response agencies.
Applied scientists at the Harvard School of Engineering and Applied Sciences (SEAS) in collaboration with researchers from Hamamatsu Photonics in Hamamatsu City, Japan, have demonstrated, for the first time, lasers in which ...
When it comes to quantum information processing and cryptography, retrieving information encoded in orthogonal quantum states can, in principle, be done perfectly (although in practice it may be hard to implement). When it ...
When a snowball melts, you can tell it has achieved a liquid state when the frigid water drips through your fingers. But if you could follow the melting process, driven by the heat of your hand, from its very first moments ...
