Like a whirlpool, a new light-based communication tool carries data in a swift, circular motion. The optics advancement could become a central component of next generation computers designed to handle society's growing demand for information sharing. It may also be a salve to those fretting over the predicted end of Moore's Law.
Over the past decade, the number of virtual field trips created to simulate in-person field excursions has grown, but one aspect of physical fieldwork is not commonly replicated: Virtual explorers do not often return to their desks with collections of virtual rocks. Three-dimensional virtual samples can enhance just about any geoscience activity, from online college courses to remote research collaboration.
A website with search and interaction history can be just as engaging as chatting with an online human agent, or robot helper, according to researchers.
Women who engaged on social media after a breast cancer diagnosis expressed more deliberation about their treatment decision and more satisfaction with the path they chose, a new study finds.
Researchers have unveiled a new photo-editing method for correcting distortions in 'selfies,' photos taken at abnormally close range, to make them look more like conventional portraits. The techniques have broader implications for adjusting and animating photos.
Researchers have successfully pulled off a feat that both sci-fi fans and Michael Phelps could appreciate. Using a rotating magnetic field they show how multiple chains of microscopic magnetic bead-based robots can link up to reach impressive speeds swimming through in a microfluidic environment. Their finding is the latest step toward using the so-called 'microswimmers' to deliver medicine and perform surgery inside the body.
A scheme to write data into next generation memory chips has been developed. The proposal requires considerably fewer resources to write data safely into memory -- even during a system failure.
RUMPEL, a ground-breaking hyperdata web browser that makes it simpler for people to access and use online data about themselves, is being rolled out to the public this month.
A new study finds a link between organizational after-hours email expectations and emotional exhaustion, which hinders work-family balance. The results suggest that modern workplace technologies may be hurting the very employees that those technologies were designed to help.
Obesity is a common problem that can result in a number of health problems including type 2 diabetes, heart disease, joint problems and stroke. Aside from changes to diet and increased levels of physical activity, behavioral counseling is effective at helping people lose weight, but previous studies have shown that to be effective intensive counseling and support is needed. An online behavioral counseling tool is effective at helping people lose weight, new research has found.
Engineers have discovered that interfacing two particular oxide-based materials makes them highly conductive, a boon for future electronics that could result in much more power-efficient laptops, electric cars and home appliances that also don't need cumbersome power supplies.
A novel phototransistor device could make the Internet faster and cheaper by replacing near-infrared wavelengths with mid-wavelength infrared, say scientists.
Any picture or text could be inkjet-printed as a solar cell, using a newly developed technology. When light is absorbed in an ordinary ink, it generates heat. A photovoltaic ink, however, coverts part of that energy to electricity. The darker the color, the more electricity is produced, because the human eye is most sensitive to that part of the solar radiation spectrum which has highest energy density.
New sentiment analysis algorithms are able to monitor the social network Twitter in search of violent groups. The system analyses both the messages these individuals share and how their relationships develop. Law enforcement authorities have already expressed interest in the tool.
Transparent electronics devices are present in today’s thin film displays, solar cells, and touchscreens. The future will bring flexible versions of such devices. Their production requires printable materials that are transparent and remain highly conductive even when deformed. Researchers have combined a new self-assembling nano ink with an imprint process to create flexible conductive grids with a resolution below one micrometer.
In computers of the future, information might be stored in the form of quantum bits. But how can a quantum bit be realized?
As cases of ADHD continue to rise among US children, pediatricians at busy community practices are getting an assist from a web-based technology to improve the quality of ADHD care and patient outcomes. A multi-institutional study reports that a new web-based software program is helping reduce ADHD behavioral symptoms in children receiving care at community pediatric practices by coordinating care and ensuring patients get the most effective ADHD medications.
After analyzing more than 20 years of Monday Night Football viewership, researchers have developed an optimization model that shows how its schedules could be improved despite the uncertainty that schedule makers face.
Researchers have developed the first placenta-on-a-chip that can fully model the transport of nutrients across the placental barrier. The flash-drive-sized device contains two layers of human cells that model the interface between mother and fetus.
Scientists use mathematical modeling to simulate human mesenchymal stem cell delivery to a damaged heart and found that using one sub-set of these stem cells minimizes the risks associated with this therapy. The study represents a development in novel strategies to repair and regenerate heart muscle and could improve stem cell treatments for heart attack patients.
