A user-controlled file security scheme for cloud services

By securing data files with a 'need-to-know' decryption key, researchers at Singapore's Agency for Science, Technology and Research (A*STAR) have developed a way to control access to cloud-hosted data in real time, adding an extra layer of security for data sharing via the Internet.

Connecting solutions for grid resilience

Imagine Alexander Graham Bell's reaction if someone handed him an iPhone and told him that the device in his hand was the same as the large, cone-mounted transmitter he invented and used to call Thomas Watson in 1876.

A Comparison of Damaging Meteoroid and Orbital Debris Fluxes in Earth Orbit

Abstract: Low Earth orbit is populated with a substantial amount of orbital debris, and it is usually assumed that the flux from these objects contributes to most of the hypervelocity particle risk to spacecraft in this region. The meteoroid flux is known to be dominant at very low altitudes (less than 300 km), where atmospheric drag rapidly removes debris, and at very high altitudes (beyond geostationary), where debris is practically non-existent. The vagueness of these boundaries and repeated questio...

Classical synchronization indicates persistent entanglement in isolated quantum systems

As if by magic, seemingly independent pendulum clocks can come together to tick simultaneously and in synchrony. The phenomenon of "self-organized synchronization" frequently occurs in nature and engineering and is one of the key research fields of Marc Timme's team at the Max Planck Institute for Dynamics and Self-Organization. The physicists in Göttingen are part of a German-Italian collaboration which has now published an amazing discovery in Nature Communications: even quantum systems can synchronize through self-organization, without any external control. This synchronization manifests itself in the strangest property of the quantum world – entanglement.
