Conflicting views on social media balanced by an algorithm

Tue, 12/05/2017 - 15:42
Researchers have designed an algorithm that is able to balance the information exposure so that social media users can be exposed to information from both sides of the discussion.

First step toward practical application of holographic memory with magnetic assist

Tue, 12/05/2017 - 14:36
Scientists have successfully applied magnetic assist recording to magnetic-holographic memory to reduce recording energy consumption and achieve error-free data reconstruction. This new technology is promising for practical application of magnetic-holographic memory as a rewritable, ultra-high-density, high-speed optical information storage medium.

Virtual reality users must learn to use what they see

Mon, 12/04/2017 - 22:28
When most people put on a virtual reality headset, they still treat what they see like it's happening on any run-of-the-mill TV screen, research finds.

New robots can see into their future

Mon, 12/04/2017 - 21:23
Researchers have developed a robotic learning technology that enables robots to imagine the future of their actions so they can figure out how to manipulate objects they have never encountered before. In the future, this technology could help self-driving cars anticipate future events on the road and produce more intelligent robotic assistants in homes, but the initial prototype focuses on learning simple manual skills entirely from autonomous play.

Replicating peregrine falcon attack strategies could help down rogue drones

Mon, 12/04/2017 - 20:06
Peregrine falcons steer their attacks using the same control strategies as guided missiles, new research indicates. The findings could be applied to the design of small, visually guided drones that can take down other 'rogue' drones in settings such as airports or prisons.

Computer simulations reveal roots of drug resistance

Mon, 12/04/2017 - 19:47
New supercomputer simulations have revealed the role of transport proteins called efflux pumps in creating drug-resistance in bacteria, research that could lead to improving the drugs' effectiveness against life-threatening diseases and restoring the efficacy of defunct antibiotics.

Electricity generated from low-cost biomaterial

Mon, 12/04/2017 - 19:47
Mobile phone speakers and motion detectors in cars and video games may soon be powered by electricity generated from low cost and sustainable biomaterials, according to new research.

Nature's toughest substances decoded

Mon, 12/04/2017 - 16:51
Researchers have developed computer simulations to decode nature's toughest materials, like seashells and tooth enamel, to guide making synthetic multifunctional composites.

Online risks are routine for teens, most bounce back

Mon, 12/04/2017 - 15:53
Teens routinely encounter online risks, such as sexual solicitations, cyberbullying and explicit material, but research shows that the negative effects of such exposure appear to be temporary, vanishing for most teens in less than a week. A new study found that typical teens seem to be resilient and cope with most online risks, moving beyond the temporary negative impacts quickly.

Computerized biology, or how to control a population of cells with a computer

Mon, 12/04/2017 - 15:53
Researchers explain computer control of cellular processes. Hybrid experimental platforms combining microscopes and software are enabling researchers to interface living cells with control algorithms in real time. The research illustrates that these solutions make it possible to create new and easily reprogrammable behaviors of cell populations. This external control of living tissue would then become a formidable research tool for acquiring a detailed understanding of the biological role of certain proteins.

Advances to brain-interface technology provide clearer insight into visual system

Mon, 12/04/2017 - 15:53
Engineers and cognitive neuroscientists have demonstrated that a new high-density EEG can capture the brain's neural activity at a higher spatial resolution than ever before. This next-generation brain-interface technology is the first noninvasive, high-resolution system of its kind, providing higher density and coverage than any existing system. It has the potential to revolutionize future clinical and neuroscience research as well as brain-computer interfaces.

How can humans keep the upper hand on artificial intelligence?

Mon, 12/04/2017 - 14:49
Researchers have shown how human operators can maintain control over a system comprising several agents that are guided by artificial intelligence.

Swarm-based simulation strategy proves significantly shorter

Mon, 12/04/2017 - 14:49
How long do computer simulations need to run to be accurate? Speeding up processing time to elucidate highly complex study systems like the dynamics of biological molecules has been a common challenge. Now, scientists have developed a practical solution to the problem of saving time when using computer simulations that require bringing a complex system into a steady state of equilibrium and measuring its equilibrium properties.

Helping hands guide robots as they learn

Mon, 12/04/2017 - 14:49
Researchers help humans and robots collaborate by enabling real-time interactions that modify a robot's path to its goal. The study will help robots make the transition from structured factory floors to interactive tasks like rehabilitation, surgery and training programs in which environments are less predictable.

Ideal size for computer memory

Mon, 12/04/2017 - 14:15
Ultraprecise simulation of a computer storage technology known as CBRAM reveals its optimal geometry: an insulator roughly ten atoms thick sandwiched between two electrodes.

Medical note system could boost patients' engagement in their health care

Fri, 12/01/2017 - 23:15
Patients could benefit if they are invited to co-produce medical notes, called 'OurNotes,' with their doctors, rather than merely reading them. The practice may also benefit doctors by reducing time spent on documentation, suggests a new report.

Graphene nano 'tweezers' can grab individual biomolecules

Fri, 12/01/2017 - 20:09
Researchers have found yet another remarkable use for the wonder material graphene -- tiny electronic 'tweezers' that can grab biomolecules floating in water with incredible efficiency. This capability could lead to a revolutionary handheld disease diagnostic system that could be run on a smart phone.

Kids and screen time: Signs your child might be addicted

Fri, 12/01/2017 - 17:29
It's a familiar sight in the majority of young families: young children bent over a screen for hours, texting or gaming, lost in a digital world.

Monitoring security glass panes: Smart alarm system recognizes attempted break-ins

Fri, 12/01/2017 - 15:47
There is a huge selection of glass break detectors on the market. Although these detectors reliably trigger an alarm when window panes break, they do not register all other ways in which burglars can interfere with a pane. To counter this, researchers have created a new type of alarm system that recognizes any attempt to manipulate the window. It registers temperature changes in real time as well as vibrations caused by external interference with the glass, leaving burglars with no chance.
