Computer chips with superconducting circuits -- circuits with zero electrical resistance -- would be 50 to 100 times as energy-efficient as today's chips, an attractive trait given the increasing power consumption of the massive data centers that power the Internet's most popular sites.
Computer simulations have been used to show how bacteria are able to destroy antibiotics -- a breakthrough which will help develop drugs which can effectively tackle infections in the future.
Today’s smartphone user can obtain a lot of data about his or her health, thanks to built-in or separate sensors. Researchers now take this health monitoring to a higher level. Using the system he developed, the smartphone also acts as an ‘activity coach’: it advices the user to walk or take a rest. In what way the user wants to be addressed, is typically something the system learns by itself.
A new computational model may help illuminate the conditions surrounding tumor dormancy and the switch to a malignant state. The so-called cellular automaton model simulated various scenarios of tumor growth leading to tumor suppression, dormancy or proliferation.
Despite the growing popularity of using computer simulation to help teach college anatomy, students learn much better through the traditional use of human cadavers, according to new research.
Researchers used supercomputer simulations to dispel a popular misconception about magnesium-ion batteries that should help advance the development of multivalent ion battery technology.
The familiar interfaces of online social networking sites might be adapted to allow us to interact more efficiently with our networked devices such as cars, domestic appliances and gadgets. The concept would also extend to the idea of those devices connecting with each other as necessary to improve efficiency of heating and lighting, make our home entertainment systems smarter and much more.
Unwanted intruders are finding it more and more difficult to hack computer systems and networks thanks to today's advanced detection technologies. With the help of emulation-based technologies, many attacks can be detected at an early stage. However, even these technologies are not watertight.
The use of electronic health care services (versus more traditional methods) to reduce the high incidence of heart disease in China will be debated by leading cardiologists from around the world. “Clearly there is an urgent need to do something to reverse the trend in China where one in five people have cardiovascular disease and smoking and obesity are major issues,” said one expert.
New ways of documenting and sharing artifacts are being explored in recent study. Archaeologists are now using the tools of the 21st century to explore the past, researchers say, and are exploring how structured light 3D scanning can capture both the surface and geometry of artifacts. This technology will eventually help put artifacts that have been excavated in pieces back together again, they hope. The same technology can produce three-dimensional models of artifacts, allowing researchers around the world to study pieces online.
Two professors are figuring out the most effective ways we’re influenced to give away personal information online and what warnings would be most effective to get us to stop.
Engineers have developed a surgical robot designed to perform brain surgery by entering through the cheek instead of the skull that can operate on a patient in an MRI scanner. Additionally, the engineers have designed the system so that much of it can be made using 3-D printing in order to keep the price low.
A software program that allows climate researchers to access historical climate data for the entire global surface (excluding the poles) has been developed. This software include the oceans, and is based statistical research into historical climates.
Researchers have been working to make prostheses more comfortable in a twofold approach: sensors that detect how the prosthesis fits and a system to make the fit better, pointing out that it doesn't matter how high-tech a prosthesis is if it's not comfortable.
A researcher has shown that tiny tweaks to the soundtrack can make TV ads much more memorable, increasing their commercial impact.
A longitudinal study of broadband Internet usage illuminates the relationship among services, performance, pricing, and demand in developed and developing countries.
Computers of the future could be built from 'magnetic tornadoes,' according to new research into nanotechnology. Using computer simulations, the team have shown it is possible to create magnetic 'logic gates', the fundamental building blocks of a CPU, using magnetic materials.
A study of tamper-resistant voting methods revealed that only 58 percent of ballots were successfully cast across three voting systems.
From performing surgery and flying planes to babysitting kids and driving cars, today’s robots can do it all. With chatbots such as Eugene Goostman recently being hailed as “passing” the Turing test, it appears robots are becoming increasingly adept at posing as humans. While machines are becoming ever more integrated into human lives, the need to imbue them with a sense of morality becomes increasingly urgent. But can we really teach robots how to be good?
A new implant gives patients the opportunity to send daily updates about their heart condition to physicians. The system features a paper clip-sized sensor that is implanted in the pulmonary artery to measure pulmonary artery pressure. Increased pressure along with weight and blood pressure changes are indications of worsening heart failure. It also allows patients to transmit daily sensor readings from their home to their physician or nurse allowing for personalized and proactive management of their condition.
