Do you look like your name? People can match names to faces of strangers with surprising accuracy

Mon, 02/27/2017 - 15:08
If your name is Fred, do you look like a Fred? You might -- and others might think so, too. New research has found that people appear to be better than chance at correctly matching people's names to their faces, and it may have something to do with cultural stereotypes we attach to names.

Tracking the movement of cyborg cockroaches

Mon, 02/27/2017 - 15:07
New research offers insights into how far and how fast cyborg cockroaches -- or biobots -- move when exploring new spaces. The work moves researchers closer to their goal of using biobots to explore collapsed buildings and other spaces in order to identify survivors.

High-performance computation is available by cloud computing

Mon, 02/27/2017 - 13:25
A group of researchers has developed the world's first system for flexibly providing high-performance computation by cloud computing.

New software allows for 'decoding digital brain data'

Fri, 02/24/2017 - 18:39
New software allows for 'decoding digital brain data' to reveal how neural activity gives rise to learning, memory and other cognitive functions. The software can be used in real time during an fMRI brain scan.

Study examines ways to use demand information to adjust capacity

Fri, 02/24/2017 - 16:17
A new study derived optimal policies and data-driven, problem-solving techniques for firms to learn about demand so that they can decide when and by how much they should adjust their capacity level.

Interactive health apps may inspire healthy behaviors, but watch the tone

Fri, 02/24/2017 - 16:17
Just like real doctors and nurses, online health tools with good -- but controlled -- communication skills can promote healthier lifestyles, according to researchers. However, if their tone is conversational, these tools may lull users into a false sense of comfort, they add. In a study, people who experienced a back-and-forth interaction with an online health risk assessment website were more likely to follow the health behaviors suggested by the tool.

Using Twitter may increase food-poisoning reporting

Thu, 02/23/2017 - 21:02
Nearly 1 in 4 U.S. citizens gets food poisoning every year, but very few report it. Twitter communications between the public and the proper government authorities could improve foodborne illness reporting as well as the steps that follow, according to a new study.

Desks join the internet of things

Thu, 02/23/2017 - 19:47
The internet of things promises to revolutionize the way we live, connecting the objects in our homes to one another and to the vast array of information available online. The possibilities are enormous, and one benefit may be improving our health.

As thin as an atom: A revolutionary semiconductor for electronics

Thu, 02/23/2017 - 19:44
Semiconductors that are as thin as an atom are no longer the stuff of science fiction. A new two-dimensional material could revolutionize electronics, say researchers.

Understanding the impact of delays in high-speed networks

Thu, 02/23/2017 - 19:21
In a world increasingly reliant on high-speed networks, introducing microsecond delays into such systems can have profound effects.

Computer bots are more like humans than you might think, having fights lasting years

Thu, 02/23/2017 - 19:21
Bots appear to behave differently in culturally distinct online environments. A new paper says the findings are a warning to those using artificial intelligence for building autonomous vehicles, cyber security systems or for managing social media.

New gene sequencing software could aid in early detection, treatment of cancer

Thu, 02/23/2017 - 17:43
A research team has developed and successfully tested new computational software that determines whether a human DNA sample includes an epigenetic add-on linked to cancer and other adverse health conditions.

Computing with biochemical circuits made easy

Thu, 02/23/2017 - 16:48
A software tool and a systematic wet-lab procedure proven in practice are an advance in the design and construction of circuits made of DNA.

Researchers teach drones to land themselves on moving targets

Thu, 02/23/2017 - 16:47
Researchers are using artificial intelligence called fuzzy logic to get drones to navigate and land themselves on moving platforms. This holds promise for commercial uses such as delivering packages from moving vehicles.

Mathematics supports a new way to classify viruses based on structure

Thu, 02/23/2017 - 15:18
Scientists have found new evidence to support a classification system for viruses based on viral structure.

Paving the way for ionotronic nanodevices

Thu, 02/23/2017 - 14:21
Ionotronic devices rely on charge effects based on ions, instead of electrons or in addition to electrons. These devices open new opportunities for creating electrically switchable memories. Researchers have visualized how oxygen ion migration in a complex oxide material causes the material to alter its crystal structure in a uniform and reversible fashion, prompting large modulations of electrical resistance. Resistance-switching random access memories could utilize this effect.

Sum of their parts: Researchers use math to foster environmental restoration

Thu, 02/23/2017 - 02:53
Resource management boundaries seldom align with environmental systems, which can lead to scale mismatch or spatial misalignments. Researchers employ analytic modeling to counter this challenge and foster collaboration and efficient coordination of stakeholders' joint restoration efforts.

Tiny fibers open new windows into the brain

Wed, 02/22/2017 - 19:57
For the first time, a single multifunction flexible fiber no bigger than a human hair, has successfully delivered a combination of optical, electrical and chemical signals back and forth into the brain.

Making it harder to 'outsmart' concussion tests

Wed, 02/22/2017 - 17:56
Concussion testing on the athletic field depends upon comparing an athlete's post-concussion neurocognitive performance with the results of a previously administered baseline test. Experts believe some athletes, in hopes of a quicker post-injury return to play, may 'sandbag' the concussion test by giving a lackadaisical baseline performance. A researcher has developed a statistical technique to detect when an athlete is sandbagging.

Likelihood of dieting success lies within your tweets

Tue, 02/21/2017 - 20:07
There is a direct link between a person's attitude on social media and the likelihood that their dieting efforts will succeed. In fact, researchers have now determined that dieting success ­-- or failure -- can be predicted with an accuracy rate of 77 percent based on the sentiment of the words and phrases one uses on Twitter.
