Physicists have given Schrödinger's famous cat a second box to play in, and the result may help further the quest for reliable quantum computing.
One of the undeniable powers of social media is its ability to influence people and their behaviors. This is especially true, a study finds, when it comes to alcohol use. Researchers found that when participants in a study were exposed to ads touting beer, as opposed to those selling bottled water, they were more inclined to consider drinking alcohol.
Black holes are still very mysterious celestial bodies which, according to the majority of physicists, do not, however, escape the laws of thermodynamics. As a result, these physical systems possess an entropy though no real agreement has been reached about the microscopic origin of this propriety and how it should be calculated. Scientists have now achieved important results in this calculation by applying a new formalism (Group Field Theory) of Loop Quantum Gravity (LQG), a very popular approach in the area of quantum gravity.
A team of scientists spends its days incorporating millions of atmospheric observations, sophisticated graphic tools and lines of computer code to create computer models simulating the weather and climate conditions responsible for hurricanes.
In a computational analysis of the words used by more than 65,000 consenting Facebook users in some 10 million messages, it was discovered that women use language that is warmer and more agreeable than men.
Machine-learning algorithms increasingly make decisions about credit, medical diagnoses, personalized recommendations, advertising and job opportunities, among other things, but exactly how usually remains a mystery. Now, new measurement methods could provide important insights to this process.
In 1977, Princeton mathematician Paul Seymour made a conjecture about certain large graphs. Nearly 40 years later, mathematicians have come up with a proof he was right. The conjecture is 13 words long; the proof covers 120 pages of math reasoning.
A new study asserts that the three-parameter 'alpha-beta-gamma' (ABG) model used in the past by 3GPP for predicting signal coverage might spell trouble at frequencies above 6 gigahertz (GHz).
The ubiquitous Chat Bot popping up on websites asking if you need help has become standard on many sites. We dismiss, we engage, but do we trust the algorithm that is aiding our experience? Giving us answers and advice? A recent study found that participants were less likely to return to an automated advisor if given bad advice over a human advisor under the same circumstances.
The 'Internet of Things' could make cities 'smarter' by connecting an extensive network of tiny communications devices to make life more efficient. But all these machines will require a lot of energy. Rather than adding to the global reliance on fossil fuels to power the network, researchers say they have a new solution. They report on a single device that harvests wind and solar energy.
GPS-based navigation, communication systems, electrical power grids and financial networks all rely on the precise time kept by a network of around 500 atomic clocks located around the world. Researchers now present a way to use optical clocks for more accurate timekeeping than is possible with today's system of traditional atomic clocks. The researchers also measured an optical clock's frequency -- analogous to it's 'ticking' -- with unprecedented precision.
With the rapid proliferation of smart mobile devices, and the subsequent increase in data that is being gathered, the challenge is: how do we harness it?
Despite policy pressure on GPs to offer consultations by email or internet video programs such as Skype, few GPs do and most have no plans to introduce them in future, according to a new study from the United Kingdom.
A study shows which psychological characteristics of some new mothers may affect how they use Facebook to show off their baby. The research concluded that those mothers who posted more on Facebook tended to report more depressive symptoms after nine months of parenthood than other moms.
A mathematical approach for studying local magnetic interactions has helped scientists understand the magnetic properties of a material with long-range magnetic order.
Parents struggling to find and afford therapy for their child with autism may eventually be able to provide that therapy themselves with the help of telehealth training, a new report suggests.
For the first time, two mathematicians have created a 3-D simulation of the mass transport capabilities of mode-2 waves. Such models will help define how mode-2 waves can carry materials that are either beneficial (such as phytoplankton and other food sources) or detrimental (such as crude oil and other contaminants) between ecosystems.
Excessive internet use contributes to the development of school burnout. School burnout, in turn, may lead to excessive internet use or digital addiction. Mind the Gap, a longitudinal research project in Finland, has established a link between digital addiction and school burnout in both comprehensive school and upper secondary school students.
Scientists are proposing a new method for creating extremely strong spin currents. They are essential for spintronics, a technology that could replace today's electronics.
Telemedicine, which allows doctors to communicate, diagnose and even treat their patients remotely is on the rise thanks to advances in information technology. It allows healthcare workers to securely monitor patients in inaccessible parts of the world as well as providing more timely responses for patients in many situations. New research suggests that the well-known social networking site, Facebook, and smart phone use could make telemedicine even more common and useful in healthcare.
