Blanket of light may give better quantum computers Posted: 17 Oct 2019 11:11 AM PDT Researchers describe how -- by simple means -- they have created a 'carpet' of thousands of quantum-mechanically entangled light pulses. The discovery has the potential to pave the way for more powerful quantum computers. |
Highest throughput 3D printer is the future of manufacturing Posted: 17 Oct 2019 11:10 AM PDT Researchers have developed a new, futuristic 3D printer that is so big and so fast it can print an object the size of an adult human in just a couple of hours. |
Weaving quantum processors out of laser light Posted: 17 Oct 2019 11:10 AM PDT Researchers open a new avenue to quantum computing with a breakthrough experiment: a large-scale quantum processor made entirely of light. |
Darn you, R2! When can we blame robots? Posted: 17 Oct 2019 09:52 AM PDT A recent study finds that people are likely to blame robots for workplace accidents, but only if they believe the robots are autonomous. |
Posted: 17 Oct 2019 09:19 AM PDT Engineers have found a way to significantly speed up the planning process required for a robot to adjust its grasp on an object by pushing that object against a stationary surface. Whereas traditional algorithms would require tens of minutes for planning out a sequence of motions, the new team's approach shaves this planning process down to less than a second. |
Bio-circuitry mimics synapses and neurons in a step toward sensory computing Posted: 17 Oct 2019 08:49 AM PDT Researchers have demonstrated bio-inspired devices that accelerate routes to neuromorphic, or brain-like, computing. Their discovery could support the emergence of computing networks modeled on biology for a sensory approach to machine learning. |
First demonstration of one petabit per second network node Posted: 17 Oct 2019 08:17 AM PDT Computer scientists have demonstrated the first large-scale optical switching testbed capable of handling 1 Petabit per second optical signals. This demonstration made use of state-of-the-art large-scale and low-loss optical switches based on MEMS technology, three types of next-generation spatial-division multiplexing fibers, and included data rates from 10 Terabit per second to 1 Petabit per second. This is a major step forward towards practical petabit-class backbone networks. |
Daily exposure to blue light may accelerate aging, even if it doesn't reach your eyes Posted: 17 Oct 2019 07:12 AM PDT Prolonged exposure to blue light, such as that which emanates from your phone, computer and household fixtures, could be affecting your longevity, even if it's not shining in your eyes. New research suggests that the blue wavelengths produced by light-emitting diodes damage cells in the brain as well as retinas, according to a new study in a model organism. |
Mathematical modeling vital to tackling disease outbreaks Posted: 17 Oct 2019 04:55 AM PDT Predicting and controlling disease outbreaks would be easier and more reliable with the wider application of mathematical modelling, according to a new study. |
Information theory as a forensics tool for investigating climate mysteries Posted: 17 Oct 2019 04:55 AM PDT During Earth's last glacial period, temperatures on the planet periodically spiked dramatically and rapidly. A new article suggests that mathematics from information theory could offer a powerful tool for analyzing and understanding these mysterious events. |
New augmented reality system lets smartphone users get hands-on with virtual objects Posted: 16 Oct 2019 12:37 PM PDT A new augmented reality system places virtual objects within real-world backgrounds on cell phone screens and lets people interact with those object by hand as if they were really there. |
Consumers trust influencers less when there is a variety of choices for a product Posted: 16 Oct 2019 12:36 PM PDT Consumers have been relying on opinion leader recommendations to make choices about product quality and purchases for a long time. It is even more prominent now with the prevalence of influencers on social media platforms. The problem is, when there is a wide variety of the same product, consumers question if a positive recommendation is based on quality or personal preferences. |
Recovering 'lost dimensions' of images and video Posted: 16 Oct 2019 12:36 PM PDT Researchers have developed a model that recovers valuable data lost from images and video that have been 'collapsed' into lower dimensions. |
Clingfish biology inspires better suction cup Posted: 16 Oct 2019 12:36 PM PDT A team of engineers and marine biologists built a better suction cup inspired by the mechanism that allows the clingfish to adhere to both smooth and rough surfaces. Researchers reverse engineered the clingfish's suction disk and developed devices that cling well to wet and dry objects both in an out of water. The devices can hold up to hundreds of times their own weight. |
Family members' emotional attachment limits family firm growth Posted: 16 Oct 2019 09:46 AM PDT New research shows family-related considerations often trump a desire to grow and expand in family firms. |
Use of social media is taking place both online and offline Posted: 16 Oct 2019 09:46 AM PDT Social media has changed how people interact. However, social media use is neither static or specifically linked to certain platforms. Emerging technical capabilities, changes in lifestyle and time management as well as the increasing possibilities to engage in online and offline interaction simultaneously affect our use of social media. |
Assembler robots make large structures from little pieces Posted: 16 Oct 2019 09:46 AM PDT Systems of tiny robots may someday build high-performance structures, from airplanes to space settlements. |
Brands are resilient against 'fake news' on social media Posted: 16 Oct 2019 09:45 AM PDT 'Fake news' stories targeting corporations may be obnoxious, but a new study finds that they likely pose little threat to well-established brands. |
Computer models show clear advantages in new types of wind turbines Posted: 16 Oct 2019 09:45 AM PDT Researchers have modeled the fluid dynamics of multi-rotor wind turbines via high-resolution numerical simulations. The simulations demonstrate a clear advantage for a turbine model with four rotors. The researchers found, that the wind turbine wake recovers much faster with multi-rotor turbines, that multi-rotor turbines produce slightly more energy than single-rotor turbines, and that a turbine with four rotors as far apart as possible is the optimal construction. |
Do we trust artificial intelligence agents to mediate conflict? Not entirely Posted: 16 Oct 2019 06:49 AM PDT We may listen to facts from Siri or Alexa, or directions from Google Maps or Waze, but would we let a virtual agent enabled by artificial intelligence help mediate conflict among team members? A new study says not just yet. |
Putting the power of a film director in an autonomous drone Posted: 15 Oct 2019 11:02 AM PDT Commercial drone products can tackle some automated tasks, but one thing those systems don't address is filming artistically. Researchers have now proposed a complete system for aerial cinematography that learns humans' visual preferences. The fully autonomous system does not require scripted scenes, GPS tags to localize targets or prior maps of the environment. |
