How to 3-D print your own sonic tractor beam

Tue, 01/03/2017 - 17:23
After demonstrating the first acoustically driven tractor beam platform, researchers develop a simpler, cheaper version using 3-D printable parts and open-source electronic components for the maker community.

Streamlining the Internet of Things and other cyber-physical systems

Tue, 01/03/2017 - 17:23
Computer engineers have laid out a framework to improve research on cyber-physical systems. They encourage combining model-based design with data-based learning: in other words, merge two existing paradigms into one practice.

Quantum simulation technique yields topological soliton state in SSH model

Tue, 01/03/2017 - 17:23
Using atomic quantum-simulation, an experimental technique involving finely tuned lasers and ultracold atoms about a billion times colder than room temperature to replicate the properties of a topological insulator, a team of researchers has directly observed for the first time the protected boundary state of the topological insulator trans-polyacetylene. The transport properties of this organic polymer are typical of topological insulators and of the Su-Schrieffer-Heeger (SSH) model.

Scientists turn memory chips into processors to speed up computing tasks

Tue, 01/03/2017 - 15:18
A team of international scientists has found a way to make memory chips perform computing tasks. The advance means data could now be processed in the same spot where it is stored, leading to much faster and thinner mobile devices and computers.

Random access memory on a low energy diet

Tue, 01/03/2017 - 15:18
Memory chips are among the most basic components in computers. The random access memory is where processors temporarily store their data, which is a crucial function. Researchers have now managed to lay the foundation for a new memory chip concept. It has the potential to use considerably less energy than the chips produced to date -- this is important not only for mobile applications but also for big data computing centers.

A social reboot for illegal downloaders

Tue, 01/03/2017 - 13:43
Unauthorized downloading of digital goods, including copyright music, videos, computer games, and images has become an increasing problem for content providers and those who hold the copyright on such goods and expect remuneration for distribution. A new research study suggests that content providers must take a pragmatic view based on social consensus to persuade illicit downloaders that their behavior is economically and ethically unacceptable behavior among their peer group or other social group to which they belong.

Novel hardware-based modeling approach for multi-robot tasks

Thu, 12/29/2016 - 16:56
Technological revolution means robots no longer are the song of the future. The Governor of the Bank of England predicts today that up to half of British workforce face redundancy in the imminent 'second machine age'. No wonder, the research of multi-robot systems generates serious buzz both for promising (albeit at times scary) results and for their application prospects in the real world.

While painful, surge pricing is still a good deal

Wed, 12/28/2016 - 15:26
New research shows price hikes in ride-sharing services such as Uber and Lyft during peak use times, such as New Year’s Eve, can actually benefit both drivers and consumers.

Control algorithms could keep sensor-laden balloons afloat in hurricanes for a week

Tue, 12/27/2016 - 16:02
Controls engineers have developed practical strategies for building and coordinating scores of sensor-laden balloons within hurricanes. Using onboard GPS and cellphone-grade sensors, each drifting balloon becomes part of a 'swarm' of robotic vehicles, which can periodically report, via satellite uplink, their position, the local temperature, pressure, humidity and wind velocity.

Investigations of the skyrmion Hall effect reveal surprising results

Tue, 12/27/2016 - 16:02
Researchers have made another important breakthrough in the field of future magnetic storage devices.

Realistic training for extreme flight conditions

Tue, 12/27/2016 - 13:33
Missions at sea, in mountainous regions or close to skyscrapers are extremely risky for helicopter pilots. The turbulent air flows near oil rigs, ships, cliffs and tall buildings can throw a helicopter off balance and cause a crash. To provide pilots with optimal preparation for these challenging conditions, engineers are developing new simulation software.

A wolverine-inspired material

Mon, 12/26/2016 - 04:19
Scientists have developed a transparent, self-healing, highly stretchable conductive material that can be electrically activated to power artificial muscles and could be used to improve batteries, electronic devices, and robots.

Hack-proofing our devices

Sat, 12/24/2016 - 05:04
A researcher is building better safeguards into the everyday technologies of radio-frequency identification (RFID) and mobile phones.

Linking human genome sequences to health data will change clinical medicine, says expert

Fri, 12/23/2016 - 00:15
The value of intersecting the sequencing of individuals' exomes (all expressed genes) or full genomes to find rare genetic variants -- on a large scale -- with their detailed electronic health record (EHR) information may have big benefits for medicine, reports a new article.

Electron-photon small-talk could have big impact on quantum computing

Thu, 12/22/2016 - 19:35
In a step that brings silicon-based quantum computers closer to reality, researchers have built a device in which a single electron can pass its quantum information to a particle of light.

The sound of quantum vacuum

Thu, 12/22/2016 - 18:16
Quantum mechanics dictates sensitivity limits in the measurements of displacement, velocity and acceleration. A recent experiment probes these limits, analyzing how quantum fluctuations set a sensor membrane into motion in the process of a measurement. The membrane is an accurate model for future ultraprecise quantum sensors, whose complex nature may even hold the key to overcome fundamental quantum limits.

Researchers use mathematical modeling to explain evolutionary phenomenon that leads to treatment resistance

Thu, 12/22/2016 - 14:51
Reserachers are using mathematical models to explain how bacteria and cancer cells exploit an evolutionary process known as bet-hedging to resist medical intervention.
