Nano Piano’s Lullaby Could Mean Storage Breakthrough

Nano Piano’s Lullaby Could Mean Storage Breakthrough

Researchers from the University of Illinois at Urbana-Champaign have demonstrated the first-ever recording of optically encoded audio onto a non-magnetic plasmonic nanostructure, opening the door to multiple uses in informational processing and archival storage.   “The chip’s dimensions are roughly equivalent to the thickness of human hair,” explained Kimani Toussaint, an associate professor of mechanical [...]

New Highly Efficient Search Engine Developed

New Highly Efficient Search Engine Developed

Researchers at the Helsinki Institute for Information Technology HIIT have developed a new search engine that outperforms current ones, and helps people to do searches more efficiently.   The SciNet search engine is different because it changes internet searches into recognition tasks, by showing keywords related to the user’s search in topic radar. People using [...]

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 [...]

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 [...]
