Study exposes major flaw in classic artificial intelligence test

Tue, 07/05/2016 - 13:20
A serious problem in the Turing test for computer intelligence is exposed in a new study.

Making astrophysical simulations more accurate

Tue, 07/05/2016 - 13:20
New research may result in better simulations of large astrophysical events such as supernova explosions. This work also raises hopes of finding out more about how atomic nuclei behave in neutron stars.

Teaching drones about the birds and the bees

Mon, 07/04/2016 - 12:27
Unmanned Aerial Vehicles (UAVs) of the future will be able to visually coordinate their flight and navigation just like birds and flying insects do, without needing human input, radar or even GPS satellite navigation.

Grade-school students teach a robot to help themselves learn geometry

Fri, 07/01/2016 - 01:45
Researchers create rTAG, a tangible learning environment that utilizes teachable agent framing, together with a physical robotic agent to get students away from the traditional computer monitor, keyboard, and mouse.

Low-current, highly integrable spintronics device developed

Thu, 06/30/2016 - 22:03
Scientists have developed a device capable of controlling magnetism at a lower current level than conventional spintronics devices. The new device was fabricated by combining a solid electrolyte with a magnetic material, and enabling insertion/removal of ions into/from the magnetic material through application of voltage.

Tracking brain atrophy in MS could become routine, thanks to new software

Thu, 06/30/2016 - 20:37
The loss of brain tissue, called brain atrophy, is a normal part of aging, but multiple sclerosis (MS) accelerates the process. Such atrophy is a critical indicator of physical and cognitive decline in MS, yet because measuring brain atrophy is expensive and complicated, it’s done primarily in research settings. That may be changing, say scientists.

Liability of internet 'intermediaries' in developing countries

Thu, 06/30/2016 - 18:50
If someone posts illegal content on your website, are you liable? A new project addresses that question by examining the potential liability faced by website owners and other online service providers in five countries - Brazil, Russia, India, China and Thailand. The project provides new insight on the murky area of internet intermediary liability in developing countries.

Scientists develop computer models to unravel the complexities of TB infection

Thu, 06/30/2016 - 18:09
Scientists used computers to model the formation of tuberculosis granulomas in the lung -- the non-active (latent) form of infection found in 2 billion individuals worldwide (11 million in the U.S.) that can activate to become a life-threatening infection. Employing a computer model aims to speed analysis of TB’s complex life-cycle and to identify potential new antibiotics, antibiotic targets, and biomarkers that can predict transition to active infection.

Weight-loss technologies train the brain to resist temptation

Thu, 06/30/2016 - 15:54
Can a computer game train your brain to resist sweets? The game is designed to improve a person's "inhibitory control," the part of the brain that stops you from giving into unhealthy cravings -- even when the smell of French fries is practically begging you to step inside a fast food restaurant. Researchers are testing whether a new smartphone app and computer game can change behaviors.

New tool to measure homeland security risks in US

Thu, 06/30/2016 - 14:22
Researchers have validated a new risk assessment tool that can be used by the Department of Homeland Security to help evaluate decisions and priorities in natural disasters, terrorist events, and major accidents.

Bioinformatics software developed to predict effect of cancer-associated mutations

Thu, 06/30/2016 - 14:20
A new piece of software has been developed that analyses mutations in proteins. These mutations are potential inducers of diseases, such as cancer. The development is free, easy, versatile and, above all, fast bioinformatics application that is capable of analyzing and combining the information from 40,000 proteins within the space of one minute.

Brilliant hard drive quality with magnetic field sensors made of diamond

Thu, 06/30/2016 - 13:26
Quantum mechanics is not only of high interest in fundamental research. The current progress in quantum technologies promises numerous innovations of industrial relevance, which will be transferred into the economy within the next five to ten years. Researchers are now developing highly sensitive diamond probes as a basis for novel quantum sensors. These are able to characterize smallest magnetic fields with a spatial resolution in the nanometer range.

The irony of awkward: Study shows the effects of problematic media on social withdrawal for young millennials

Thu, 06/30/2016 - 13:21
Not all withdrawn individuals are the same, but for emerging adults who do everything they can to avoid social interaction, combining that with things like violent video games or pornography can cause big problems.

Wearable technology gets good ratings from plastic surgeons

Wed, 06/29/2016 - 18:52
Plastic surgeons see some clear advantages of using Google Glass in the operating room, reports a new survey.

Key power-splitting component for terahertz waves

Wed, 06/29/2016 - 16:58
One of the most basic components of any communications network is a power splitter that allows a signal to be sent to multiple users and devices. Researchers have now developed just such a device for terahertz radiation -- a range of frequencies that may one day enable data transfer up to 100 times faster than current cellular and Wi-Fi networks.

Surprising qualities of insulator ring surfaces

Wed, 06/29/2016 - 16:56
Topological insulators behave like insulators at their core and allow good conductivity on their surface. They owe their characteristics to a new quantum state within the material discovered in 2007 and 2009 for 2-D and 3-D materials, respectively. Scientists studying the surface of ring-shaped, or toric, topological insulators, have just discovered some characteristics that had only previously been confirmed in spheres.

Crowd-sourced competition to create 'big data' diagnostic tools

Wed, 06/29/2016 - 14:58
A crowdsourced collaboration/competition known as DREAM 9 set out three years ago to develop ideas for computational tools that would help treat patients with acute myeloid leukemia.

Skype data of 500 million people reveals the real patterns of social adoption

Wed, 06/29/2016 - 14:02
Global patterns of adoption spreading are induced by local adoption cascades initiated by multiple spontaneous adopters arriving at a constant rate, amplified by a large number of adoptions induced by social influence, and controlled by individuals who are immune to the actual adoption. This study shows that the structure of real-world adoption clusters is radically different from previous expectations. Vulnerable adoptions, induced by a single adopting neighbor, appear to be important only locally. Instead stable adopters, who are initially resisting to be exposed, are actually responsible for the emergence of global social adoption.

Vision through the clouds

Wed, 06/29/2016 - 13:48
Poor weather can often make the operation of rescue helicopters a highly risky business, and sometimes even impossible. A new helmet-mounted display may in the future be able to help pilots detect hazards at an early stage, even when their visibility is severely impaired: the information required to do this is created in an on-board computer and imported into digital eye glasses.

Engineers to use cyborg insects as biorobotic sensing machines

Tue, 06/28/2016 - 18:14
A team of engineers is looking to capitalize on the sense of smell in locusts to create new biorobotic sensing systems that could be used in homeland security applications.
