Printable holograms could make holograms more widespread

(Phys.org)—Holograms have a wide variety of applications, from 3D displays to data storage, but the potential applications are currently limited by the complexity and cost of hologram fabrication. In an attempt to simplify ...

How energy-efficient is cloud computing?

(PhysOrg.com) -- Conventionally, data storage and data processing are done at the user's own computer, using that computer's storage system and processor. An alternative to this method is cloud computing, which is Internet-based ...

A four-way switch promises greater tunability of layered materials

A scientific team from the Department of Energy's Oak Ridge National Laboratory and Vanderbilt University has made the first experimental observation of a material phase that had been predicted but never seen. The newly discovered ...

Planck finds no new evidence for cosmic anomalies

ESA's Planck satellite has found no new evidence for the puzzling cosmic anomalies that appeared in its temperature map of the Universe. The latest study does not rule out the potential relevance of the anomalies but they ...

The amazing camera that can see around corners (w/ video)

How can a person see around a blind corner? One answer is to develop X-ray vision. A more mundane approach is to use a mirror. But if neither are an option, a group of scientists led by Genevieve Gariepy have developed a ...

Researchers demonstrate holographic memory device

(Phys.org) —A team of researchers from the University of California, Riverside Bourns College of Engineering and Russian Academy of Science have demonstrated a new type of holographic memory device that could provide unprecedented ...
