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.
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.
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' 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.
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.
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.
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.
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.
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.
In a world increasingly reliant on high-speed networks, introducing microsecond delays into such systems can have profound effects.
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.
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.
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 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.
Scientists have found new evidence to support a classification system for viruses based on viral structure.
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.
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.
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.
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.
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.
