Shortening the school week to four days has a positive impact on elementary school students' academic performance in mathematics, according to researchers.
Scientists create a biological circuit by programming bacteria to alter gene expression in an entire population. They have created a biological equivalent to a computer circuit that involves multiple organisms to influence a population.
A new study found that three times as many female high school students were interested in enrolling in a computer science class if the classroom was designed to be less 'geeky' and more inviting.
Physicists have found a radical new way confine electromagnetic energy without it leaking away, akin to throwing a pebble into a pond with no splash.The theory could have broad ranging applications from explaining dark matter to combating energy losses in future technologies.
Rsearchers have developed a questionnaire to help you determine if you suffer from nomophobia or a fear of being without your mobile phone.
For more than a decade, gene sequencers have been improving more rapidly than the computers required to make sense of their outputs. Searching for DNA sequences in existing genomic databases can already take hours, and the problem is likely to get worse. Recently, scientists have been investigating techniques to make biological and chemical data easier to analyze by, in some sense, compressing it.
A study presents a new method for dealing with delays that, they conclude, keeps system-wide delays virtually constant while distributing delays among airlines more evenly. Specifically, it lets airlines distribute delays among themselves more evenly by allowing them to swap schedule slots with each other. The result, the researchers say, is more fair, without sacrificing efficiency.
Researchers are using high-performance computing to simulate the processes that take place during the first moments of photosynthesis. Using quantum mechanics as the basis, computer scientists, physicists and chemists are working together to produce simulations of the molecule in which photosynthesis occurs.
If you feel stressed out by your smartphone, it might be down to your personality as well as your phone, a new study suggests.
Robotically steering flexible needles can reach their intended target in tissue with sub-millimetre level accuracy. A major advantage of steering flexible needles is that one can avoid obstacles or sensitive tissues and can re-orient the path of the needle in real time as you insert the needle.
Nanoengineers at the University of California, San Diego used an innovative 3-D printing technology they developed to manufacture multipurpose fish-shaped microrobots -- called microfish -- that swim around efficiently in liquids, are chemically powered by hydrogen peroxide and magnetically controlled. These proof-of-concept synthetic microfish will inspire a new generation of 'smart' microrobots that have diverse capabilities such as detoxification, sensing and directed drug delivery, researchers said.
Targeted punishments could provide a path to international climate change cooperation, new research in game theory has found.
Students heading back to school can always count on one thing: Technology will be a little bit more advanced than it was last year. After all, 21st century learning experiences are increasingly enhanced by gadgets and software, and the ability to plug into worlds beyond the classroom. Even so, technology is no substitute for everyday student engagement and collaboration among students, researchers find.
Biophysicists have taken another small step forward in the quest for an automated method to infer models describing a system's dynamics -- a so-called robot scientist.
With current research suggesting that many young people don’t question the information they find online, a new study reveals the factors that are most likely to predict they will.
E-health is vital to winning the battle against heart disease, cardiology leaders said. The novel paper outlines how the ESC will exploit e-health in education and research, while tackling issues of quality control and data security.
Electronic triggers designed to search for key data, developed by researchers at Baylor College of Medicine and Michael E. DeBakey Veterans Affairs Medical Center, were able to identify and reduce follow-up delays for patients being evaluated for a diagnosis of colon or prostate cancer.
For software programmers, security tools are analytic software that can scan or run their code to expose vulnerabilities long before the software goes to market. But these tools can have shortcomings, and programmers don't always use them. New research tackles three different aspects of the issue.
Like the Rubik's Cube, a three-dimensional combination puzzle where every twist also scrambles the face opposite of it, economics puzzles are similarly interlinked -- a change in policy may lead to repercussions elsewhere.
Using computer vision, signal processing and privacy protection, a doctoral student, along with electrical and computer engineering professors, have developed "MEBook," a combination of a social narrative and gaming system that psychologists and parents can use as behavioral therapies for autistic children.
