Materials scientist have just discovered a way to give the workhorse transistor a big boost, using a new technique to incorporate vanadium oxide, one of a family of materials called functional oxides, into the device.
Soft steps and large feet can allow animals and robots to maintain high speeds on very loose soil and sand. These findings offer a new insight into how animals respond to different terrain, and how robots can learn from them.
Use of an iPad app that fosters parent-child interactions around math markedly increases children's math achievement across the school year, especially for children with parents who are habitually anxious about math.
If you want to learn how something works, one strategy is to take it apart and put it back together again. For 10 years, a global initiative called the Blue Brain Project has been attempting to do this digitally with a section of juvenile rat brain. The project presents a first draft of this reconstruction, which contains over 31,000 neurons, 55 layers of cells, and 207 different neuron subtypes.
Most robotic parts used to today are rigid, have a limited range of motion and don't really look lifelike. Inspired by both nature and biology, a scientist has designed a novel robotic finger that looks, feels and works like the real thing. Using shape memory alloy, a 3D CAD model of a human finger, a 3D printer and a unique thermal training technique, this robotic finger could ultimately be adapted for use as a prosthetic device, such as on a prosthetic hand.
For nearly nine years, researchers at Lund University have been working on developing implantable electrodes that can capture signals from single neurons in the brain over a long period of time - without causing brain tissue damage. They are now one big step closer to reaching this goal, and the results are published in the scientific journal Frontiers in Neuroscience.
A research team has created the exotic ring-shaped magnetic effects called skyrmions under ambient room conditions for the first time. The achievement brings skyrmions a step closer to use in real-world data storage as well as other novel magnetic and electronic technologies.
In support of the Department of Homeland Security (DHS), researchers have developed a concept for a more accurate method of delivering certain types of messages that could even warn users to avoid particular nearby locations.
People tend to have distinctive, personal rhythms of digital communication that persist in time, research shows. Selective monitoring of these daily rhythms for at-risk patients could have applications in health care, their reports outlines.
The promise of big data lies in researchers' ability to mine massive datasets for insights that can save lives, improve services and inform our understanding of the world.These data may be generated by surfing the web, interacting with medical devices or passing sensors. Some data may be trivial, but in many cases, data are deeply personal. They can even influence our insurance premiums or the price we pay for a product online.
Bioengineers have developed a mathematical algorithm that can "see" your intention while performing an ordinary action like reaching for a cup or driving straight up a road -- even if the action is interrupted.
Researchers have built a microbiome analysis platform called QIIME (pronounced “chime” and short for “Quantitative Insights Into Microbial Ecology”). This software will now be more readily accessible to hundreds of thousands of researchers around the world through BaseSpace, a cloud-based app store.
How many people read online privacy warnings? Few probably do. Long, detailed and technical privacy notices are the current answer to one of the greatest privacy issues of our time: websites collect information about us all the time and we frequently allow it without really knowing or understanding the conditions. Scientists have found that web design, and the information shown on the screen, does influence how and whether a user discloses personal data.
Researchers are developing a computer system that uses genetic, demographic, and clinical data to help predict the effects of disease on brain anatomy.
Crime in Los Angeles dropped dramatically when the Los Angeles Police Department deployed officers based on crime predictions made by a mathematical model, a team of scholars and police department colleagues reports today. The mathematical model would be effective in cities worldwide, the researchers said.
Online advertising based on Google search terms is a potentially effective way to deliver targeted cancer prevention education, according to a new study.
The influence of our social networks can be a powerful motivator to encourage more physical activity, say researchers in a new report. What this new study reveals is that these same positive behavior signals are also powerful in our online networks, and can be harnessed for the social good. This approach could be applied not only to encourage exercise, but also to promote vaccinations, medication compliance, and preventative care.
In about one in 20 cancer cases, the doctor can confirm that the patient has cancer -- but cannot find the source. These patients then face the prospect of a long wait with numerous diagnostic tests and attempts to locate the origin of the cancer before starting any treatment. Now, researchers have combined genetics with computer science and created a new diagnostic technology based on advanced self-learning computer algorithms which can, with 85 per cent certainty, identify the source of the disease and thus target treatment and, ultimately, improve the prognosis for the patient.
An international team of researchers have designed and synthesized a nanometer-scale DNA 'machine' whose customized modifications enable it to recognize a specific target antibody.
Those looking for data and analytical reports often turn to the American Community Survey (ACS) from the US Census, which provides data such as unemployment, median household income, and housing prices for multi-year periods. Now, using sophisticated statistical methods, researchers have developed a system that improves ACS data, allowing end users to more accurately analyze critical information in predefined geographic areas, making it easier for city, county, state and federal planners to use estimates in policy decisions.
