A second minor planet may possess Saturn-like rings

There are only five bodies in our solar system that are known to bear rings. The most obvious is the planet Saturn; to a lesser extent, rings of gas and dust also encircle Jupiter, Uranus, and Neptune. The fifth member of ...

Tiny laser gives big boost to high speed data transmission

(Phys.org) —High-speed communication just got a turbo boost, thanks to a new laser technology developed at the University of Illinois that transmits error-free data over fiber optic networks at a blazing fast 40 gigabits ...

Making quantum encryption practical

One of the many promising applications of quantum mechanics in the information sciences is quantum key distribution (QKD), in which the counterintuitive behavior of quantum particles guarantees that no one can eavesdrop on ...

Researchers at IceCube detect record energy neutrinos

(Phys.org) —Researchers at the Antarctic research station IceCube are reporting that they've detected the highest ever energy neutrinos ever observed. In their paper they've uploaded to the preprint server arXiv, the team ...

Silicon nanophotonics: Using light signals to transmit data

(Phys.org)—IBM announced today a major advance in the ability to use light instead of electrical signals to transmit information for future computing. The breakthrough technology – called "silicon nanophotonics" – allows ...

Quantum mechanics enables perfectly secure cloud computing

Researchers have succeeded in combining the power of quantum computing with the security of quantum cryptography and have shown that perfectly secure cloud computing can be achieved using the principles of quantum mechanics. ...

Using nanophotonics to reshape on-chip computer data transmission

A team at Stanford's School of Engineering has demonstrated an ultrafast nanoscale light emitting diode (LED) that is orders of magnitude lower in power consumption than today's laser-based systems and able to transmit data ...

Chemically assembled metamaterials may lead to superlenses

(PhysOrg.com) -- Nanomanufacturing technology has enabled scientists to create metamaterials -- stuff that never existed in nature -- with unusual optical properties. They could lead to "superlenses" able to image proteins, ...
