Researchers have successfully replicated a direct brain-to-brain connection between pairs of people as part of a scientific study following the team's initial demonstration a year ago. In the newly published study, which involved six people, researchers were able to transmit the signals from one person's brain over the Internet and use these signals to control the hand motions of another person within a split second of sending that signal.
A new study applies the latest computational methodologies to nationally representative data from the federal Centers for Disease Control and Prevention's Youth Risk Behavior Surveillance System. Researchers identified more than 40 different behavioral factors other than mental illness that are strongly associated with gun possession. These include heroin use, substance use on school property, having been injured in a fight, and having been a victim of sexual violence.
A new class of low-cost polymer materials, which can carry electric charge with almost no losses despite their seemingly random structure, could lead to flexible electronics and displays which are faster and more efficient.
Since 1999, the conjecture by Asher Peres, who invented quantum teleportation, has piqued the interest of many scientists in the field. According to his hypothesis, the weakest form of quantum entanglement can never result in the strongest manifestation of the phenomenon. Today, scientists have proven this conjecture to be false, thus solving one of the most famous problems in quantum information physics.
Whether physicians examine or operate on the bladder wall with an endoscope, they can catch a glimpse of only a miniscule section of the organ – their viewpoint is like that of someone looking through a keyhole. But soon, however, this perspective could be broadened to a panorama. ‘Endorama‘, a new software program, assembles this panorama from all the images acquired, researchers report.
Is there still is a place in science in modern times for the interpretation of results using rational numbers or simple ratios? In a time where supercomputers dominate scientific analysis, one expert argues that there is not enough attention being paid to the basic approaches to science of the past, which were able to profoundly illuminate our understanding of the natural world through the simplification of very complex topics and systems.
Testing of study participants who wore head-mounted display systems -- Google Glass -- found that the glasses created a partial peripheral vision obstruction, according to a study.
Scientists employed high-resolution X-ray computed tomography and digital visualization techniques to restore a rare dinosaur fossil. The focus of the study was the skull of Erlikosaurus andrewsi, a 3-4 meter large herbivorous dinosaur called a therizinosaur, which lived more than 90 million years ago during the Cretaceous Period in what is now Mongolia.
It turns out that in certain situations, combining messes can actually reduce the disorder of the whole; an international team of researchers has identified a set of conditions in which adding disorder to a system makes it more orderly. This behavior is known as antifragility, a concept introduced recently to describe similar phenomena in statistics, economics and social science.
A new statistical test that looks at the patterns of high-frequency network activity flow from brain signals can help doctors pinpoint the exact location of seizures occurring in the brain and make surgery more effective, according to researchers.
Recently, Spaniards had to re-tune all television sets as a result of the introduction of 4G mobile networks. Their data transmission speed (10 times higher than the 3rd generation’s) required a release of the frequency band hitherto occupied by several TDT channels. 4G is a fact, but we are nearing the 5G revolution. 5G network development is now underway to provide a network capacity one thousand times higher than that of existing mobile networks. But, what is 5G? How will it impact our lives and when will it become available? Who is going to make possible this leap in communications technology?
The growing disparity in economic inequality has become so stark that even Janet Yellen, Federal Reserve chairwoman, recently expressed concern. Interestingly, new research has discovered that American citizens desire an unequal, but more equal distribution of wealth and income. Lower levels of this 'unequality' are associated with decreased unethical behavior and increased motivation and labor productivity.
A team of leading criminologists have published the first-ever study on how convicted killers have used the social networking site Facebook in relation to their crimes.
The rapid increase in mobile technology such as smart phones and watches, tablets and Google Glass, has resulted in the need for more research to ensure those devices work well. But, say experts, there are no good tools to properly test mobile devices. So they invented a solution using the latest technology of Google Glass.
Integrating community housing data on such code violations as mold and cockroaches with health data can identify at-risk geographical areas of medical concern and help target patients for medical interventions, a study has demonstrated.
Collisions of heavenly bodies generate almost unimaginable levels of energy. Researchers used NASA's ultra-high-speed cannon and computer models to simulate such a collision on Vesta, the second-largest object in the asteroid belt. Their analysis of the images -- taken at a million frames per second -- shows how Vesta may have gotten the deep grooves that encircle its midsection.
Blending movement and computer programming supports girls in building computational thinking skills, according to an ongoing study. This is important research, as even with increasing demands for computationally savvy workers, there is a lack of representation among women in science, technology, engineering and mathematics fields (STEM), the researchers say.
A pioneering piece of technology will allow users to experience the world through the eyes of a person with Young-Onset Parkinson’s disease -- which could revolutionize the way carers and medical staff treat people with the degenerative condition.
Today's natural resource manager tending to the health of a stream in Louisiana needs to look upstream. Way upstream -- like Montana. Scientists have invented a way to more easily manage the extensive nature of streams.
It seems that no company can afford not to engage with its customers and potential clients via online social networking sites, such as Facebook and Twitter, these days. The likes of Facebook have become hubs for such direct company to customer interactions where queries can be quickly answered, grievances addressed and products and services promoted through a marketing model that simply did not exist when the web first went commercial long before the web 2.0 concept was realized. What companies would like to know for sure, however, is whether or not their online networking efforts offer a good return on investment in terms of the bottom line regardless of whether they improve customer relations.
