A functional MRI-compatible hemiparesis rehab device that creates a long latency stretch reflex at the exact time as a brain signal has been developed by researchers. It is designed to assist stroke victims. "The device is designed to adapt to people whether they are hyper, normo or hyporeflexive," said one developer.
Reviewing electronic health records using algorithms can successfully identify patients with previously undiagnosed hypertension, or high blood pressure, with a high rate of accuracy, researchers say. hypertension affects one in three adults in America and is referred to as the "silent killer" because it rarely exhibits any warning signs, causing many to never know they had it. Because of the nature of this serious condition, hypertension is associated with more than 50 billion of dollars in costs related to medical care and lost productivity in America alone.
If you've ever tried to watch a video on a tablet on a sunny day, you know you have to tilt it at just the right angle to get rid of glare or invest in a special filter. But now scientists are reporting that they've developed a novel glass surface that reduces both glare and reflection, which continue to plague even the best mobile displays today.
People with higher job status may be more willing to compromise privacy for security reasons and also be more determined to carry out those decisions, according to researchers.
Interested in an ultra-fast, unbreakable, and flexible smart phone that recharges in a matter of seconds? Monolayer materials may make it possible. These atom-thin sheets -- including the famed super material graphene -- feature exceptional and untapped mechanical and electronic properties. But to fully exploit these atomically tailored wonder materials, scientists must pry free the secrets of how and why they bend and break under stress. Supercomputer simulations have revealed unexpected transitions in graphene and other promising super materials under strain.
Political ideology and education levels affect when people search for climate information, research indicates. Republicans search the net for information about the weather, climate change and global warming during extremely hot or cold spells. Democrats Google these terms when they experience changes in the average temperatures. These are some of the surprising findings from a study that tracked how the temperature fluctuations and rainfall that Americans experience daily in their own cities make them scour the Internet in search of information about climate change and global warming.
A prototype of an automatic translation system for patents in the biomedical area has been developed by researchers. The system can be used to create multilingual documents with the same structure as the original patents, including images, formulae and other kinds of annotations. In addition, the system works in real time and can be incorporated in web applications.
Over the years, computer chips have gotten smaller thanks to advances in materials science and manufacturing technologies. This march of progress, the doubling of transistors on a microprocessor roughly every two years, is called Moore's Law. But there's one component of the chip-making process in need of an overhaul if Moore's law is to continue: the chemical mixture called photoresist. In a bid to continue decreasing transistor size while increasing computation and energy efficiency, chip-maker Intel has partnered with researchers to design an entirely new kind of resist.
A telephone-delivered intervention, which included automated symptom monitoring, produced clinically meaningful improvements in chronic musculoskeletal pain compared to usual care, according to a study. Pain is the most common symptom reported both in the general population and patients seen in primary care, the leading cause of work disability, and a condition that costs the United States more than $600 billion each year in health care and lost productivity. Musculoskeletal pain accounts for nearly 70 million outpatient visits annually in the United States each year. Telemedicine strategies for pain care have been proposed but not rigorously tested to date.
Brands spent $8.4 billion on mobile advertising in 2013, and that number is expected to quadruple to $36 billion by 2017, according to eMarketer. But do mobile display ads -- those tiny banner ads that pop up in your smartphone's web browser -- actually work? Researchers have found that, despite their size, mobile ads can have a big effect on consumers who are in the market for certain types of products.
Cancer’s no game, but researchers are borrowing ideas from evolutionary game theory to learn how cells cooperate within a tumor to gather energy. Their experiments, they say, could identify the ideal time to disrupt metastatic cancer cell cooperation and make a tumor more vulnerable to anti-cancer drugs.
Many parents assume the Internet leads to negative behavior in their children. But a team of researchers found kids found a sense of "community" by using the Internet in two after-school programs. By increasing at-risk children's exposure to various community-based websites, Facebook pages and other social media, one researcher said, they learn to use the Internet in a positive way.
The manipulation of atoms has reached a new level: Physicists were able to place 20 single atoms on a fully insulated surface at room temperature to form the smallest “Swiss cross”, thus taking a big step towards next generation atomic-scale storage devices.
Girls and young women who post sexy or revealing photos on social media sites are viewed by their female peers as less attractive and less competent to perform tasks, a new study indicates. One researcher's advice for girls and young women is to select social media photos that showcase their identity rather than her appearance, such as one from a trip or one that highlights participation in a sport or hobby.
Buying keywords of a popular competitors' brand names on search engines such as Google and Bing can backfire according to a new study. Firms often buy brand names of better-known rivals' to reach buyers looking for rivals' products or to be seen in the company of more popular companies. However, contrary to common belief, when an inferior brand's ad is seen next to a superior brand's web links, a large difference in reputation is further magnified in the minds of consumers.
In the movie 'Terminator 2,' the shape-shifting T-1000 robot morphs into a liquid state to squeeze through tight spaces or to repair itself when harmed. Now a phase-changing material built from wax and foam, and capable of switching between hard and soft states, could allow even low-cost robots to perform the same feat.
The type of therapy a cancer patient receives largely depends on the eye of a pathologist. However, human judgment is, by its very nature, subject to variation. To enhance the quality of diagnosis, scientists have developed a software that identifies cell structures and proteins in order to provide reliable diagnoses.
Developmental processes in all living organisms are controlled by genes. At the same time there is a continuous metabolism taking place. Researchers have analyzed this interaction between metabolism and developmental processes in flowering plants. In a recent study on flower development, changes in metabolism were linked to three-dimensional morphometric data using micro-computed tomography for the first time.
The creators of a unique kit containing anatomical body parts produced by 3D printing say it will revolutionize medical education and training, especially in countries where cadaver use is problematic. The '3D Printed Anatomy Series' is thought to be the first commercially available resource of its kind. The kit contains no human tissue, yet it provides all the major parts of the body required to teach anatomy of the limbs, chest, abdomen, head and neck.
Scientists have demonstrated for the first time a photonic router -- a quantum device based on a single atom that enables routing of single photons by single photons. This achievement is another step toward overcoming the difficulties in building quantum computers.
