Researchers are studying graphene and ammonia to develop high-speed, high-capacity random access memory. The team engineered and tested improvements in the performance of a memory structure known as a ferroelectric tunnel junction.
Computer models show how microtubules age. The models reported by researchers help explain the dynamic instability seen in microtubules, essential elements in cells' cytoskeletons.
Researchers have made great progress in recent years in the design and creation of biological circuits -- systems that, like electronic circuits, can take a number of different inputs and deliver a particular kind of output. But while individual components of such biological circuits can have precise and predictable responses, those outcomes become less predictable as more such elements are combined. Scientists have now come up with a way of greatly reducing that unpredictability, introducing a device that could ultimately allow such circuits to behave nearly as predictably as their electronic counterparts.
Computer scientists are investigating how software-defined cellular networking might be used to give smart phone users the next generation of super-superfast broadband, 5G.
The need for the wireless transfer of data will increase significantly in the coming years. Scientists therefore propose to turn some of the TV frequencies that will become free into common property and to use it to extend existing wireless networks (WiFi) instead of using the frequencies for mobile communications. Their study recommends that the additional frequencies not be marketed but made available to the population and companies at no cost.
Although hummingbirds are much larger and stir up the air more violently as they move, the way that they fly is more closely related to flying insects than it is to other birds. Now, the most detailed, three-dimensional aerodynamic simulation of hummingbird flight conducted to date has definitively demonstrated that the hummingbird achieves its nimble aerobatic abilities through a unique set of aerodynamic forces that are more closely aligned to those found in flying insects than to other birds.
Researchers have provided insight into human behavior for scientists, engineers who design and build social robots.
Energy storage devices and computer screens may seem worlds apart, but they’re not. When an electrical engineering professor teamed up with and computer scientists to make a less expensive supercapacitor for storing renewable energy, they developed a new plasma technology that will streamline the production of display screens.
Banks are increasingly issuing 'CoCo' bonds to boost the levels of equity they hold. In a crisis situation, bondholders are forced to convert these bonds into a bank's equity. To date, such bonds have been regarded only as a means of averting a crisis. A study by German economists now shows that if such bonds are badly constructed, they worsen a crisis instead of stabilizing the banking system.
A new robot for inspecting ballast water tanks on board ships is being developed. The robot is able to move independently along rails built into the tanks. At the moment, people still carry out such inspections, with ships being brought into dry dock for the purpose.
The control of certain childhood diseases is difficult, despite high vaccination coverage in many countries. One of the possible reasons for this is 'imperfect vaccines,' that is, vaccines that fail either due to 'leakiness,' lack of effectiveness on certain individuals in a population, or shorter duration of potency. In a new article, authors use a mathematical model to determine the consequences of vaccine failure and resulting disease dynamics.
New research finds that people say they care about online security but behave like they don't -- such as ignoring security warnings. To better understand how people deal with security messages, researchers simulated hacking into study subjects laptops. The responses were telling.
Researchers are developing electronics that disappear to order. When the FM frequencies are removed in Norway in 2017, all old-fashioned radios will become obsolete, leaving the biggest collection of redundant electronics ever seen – a mountain of waste weighing something between 25,000 and 30,000 tons. The same thing is happening with today's mobile telephones, PCs and tablets, all of which are constantly being updated and replaced faster than the blink of an eye. The old devices end up on waste tips, and even though we in the west recover some materials for recycling, this is only a small proportion of the whole. And nor does the future bode well with waste in mind. Technologists' vision of the future is the "Internet of Things".
The first research to use computational modeling to predict and identify the metabolic products of gastrointestinal (GI) tract microorganisms has been published by researchers. Understanding these metabolic products, or metabolites, could influence how clinicians diagnose and treat GI diseases, as well as many other metabolic and neurological diseases increasingly associated with compromised GI function.
Scientists have created video games that add an important element of fun to the repetitive training needed to improve vision in people – including adults – with a lazy eye and poor depth perception.
Researchers have developed a computer game that can detect classroom bullies, victims and bystanders. The game's behavior analyses effectively identify classroom bullies, even revealing peer aggression that goes undetected by traditional research methods, the researchers say.
Physicists have discovered a new manganese compound that is produced by tension in the crystal structure of terbium manganese oxide. The technique they used to create this new material could open the way to new nanoscale circuits.
Researchers are offering an alternative to the celebrated “Turing Test” to determine whether a machine or computer program exhibits human-level intelligence.
Researchers spent four decades studying a group of mathematically talented adolescents, finding that by mid-life they were extraordinarily accomplished and enjoyed a high level of life satisfaction. Gender, however, played a significant role in how they pursued—and defined—career, family and success. Intellectually gifted women tracked for 40 years were found to earn less money, be less present in STEM fields, and work fewer hours than their male counterparts. Despite that, they expressed a high level of personal satisfaction and sense of achievement, defining success more broadly than men to include family and community service. These observations come from the most recent round of results from the Study of Mathematically Precocious Youth (SMPY), the largest longitudinal research project of its kind. The results were posted this week to Psychological Science.
Developers have built and tested a new kind of interactive wayfinder: 3-D maps that vocalize building information and directions when touched.
