Possible Read Head for Quantum Computers

Possible Read Head for Quantum Computers

Nitrogen-vacancy centers in diamonds could be used to construct vital components for quantum computers. But hitherto it has been impossible to read optically written information from such systems electronically. Using a graphene layer, a team of scientists headed by Professor Alexander Holleitner of the Technische Universität München (TUM) has now implemented just such a read [...]

Security Risk: We Ignore Online Warnings

Security Risk: We Ignore Online Warnings

Say you ignored one of those “this website is not trusted” warnings and it led to your computer being hacked. How would you react? Would you:   A. Quickly shut down your computer? B. Yank out the cables? C. Scream in cyber terror? For a group of college students participating in a research experiment, all [...]

Cybersecurity Experts Discover Lapses in Heartbleed Bug Fix

A detailed analysis by cybersecurity experts from the University of Maryland found that website administrators nationwide tasked with patching security holes exploited by the Heartbleed bug may not have done enough. First disclosed in April 2014, Heartbleed presents a serious vulnerability to the popular OpenSSL (Secure Sockets Layer) software, allowing anyone on the Internet to [...]

Gold Nanoparticles Confine Light On Nanoscale

Gold Nanoparticles Confine Light On Nanoscale

A multidisciplinary team at the Centre d’Elaboration de Matériaux et d’Etudes Structurales (CEMES, CNRS), working in collaboration with physicists in Singapore and chemists in Bristol (UK), have shown that crystalline gold nanoparticles aligned and then fused into long chains can be used to confine light energy down to the nanometer scale while allowing its long-range [...]

Accuracy of Mobile Phone Population Mapping Demonstrated

Accuracy of Mobile Phone Population Mapping Demonstrated

A study by an international team, including the University of Southampton, has shown population maps based on anonymous mobile phone call record data can be as accurate as those based on censuses.   Their findings show maps made using mobile records are detailed, reliable and flexible enough to help inform infrastructure and emergency planners; particularly [...]

Drones Help Show How Environmental Changes Affect the Spread of Infectious Diseases

Drones Help Show How Environmental Changes Affect the Spread of Infectious Diseases

Unmanned aerial vehicles, or drones, can collect detailed information in real time at relatively low cost for ecological research. In a new Opinion piece published in the Cell Press journal Trends in Parasitology, experts demonstrate that drones can be used to understand how environmental factors influence the spread of infectious diseases.   “Drones can provide [...]

Future Computers Built from Magnetic ‘Tornadoes’

Magnetic materials form the basis of most hard disc drives as they are able to store data. A team from the University of Sheffield’s Faculty of Engineering have been investigating whether they could also be used to perform calculations, and so take on the role of a computer’s central processing unit (CPU). Lead researcher, Dr [...]

Quantum Info Transmitted Through Atmosphere

Quantum Info Transmitted Through Atmosphere

It could be difficult for the NSA to hack encrypted messages in the future — at least if a technology being investigated by scientists at the Max Planck Institute for the Science of Light in Erlangen and the University Erlangen-Nürnberg is successful: quantum cryptography. The physicists are now laying the foundation to make this technique, [...]
