Graphene to Boost Internet Speed
Graphene, the strongest material on Earth, could help boost broadband internet speed. U.K. researchers have found a way to increase its sensitivity in optical communication systems.
What's the Latest Development?
Thanks to its superconductivity, scientists believe graphene, the world's strongest material, can be used to increase Internet speeds by improving on electronic components, such as the receivers used in fibre optic data connections. "The material's use in photo-electrical systems is not new. Scientists had previously managed to produce a simple solar cell by placing microscopic metallic wires on top of graphene sheets and shining light onto them. Its superconductive properties meant that electrons could flow at high speed with extreme mobility."
What's the Big Idea?
Discovered in 2004, graphene has been hailed as a 'wonder material' that has the potential to revolutionize commercial and personal electronics. Professor Kostya Novoselov, who was awarded the Nobel Prize in 2010 for discovering the material, says it holds promise for future technologies: "The technology of graphene production matures day-by-day, which has an immediate impact both on the type of exciting physics which we find in this material, and on the feasibility and the range of possible applications."
These five main food groups are important for your brain's health and likely to boost the production of feel-good chemicals.
We all know eating “healthy” food is good for our physical health and can decrease our risk of developing diabetes, cancer, obesity and heart disease. What is not as well known is that eating healthy food is also good for our mental health and can decrease our risk of depression and anxiety.
Infographics show the classes and anxieties in the supposedly classless U.S. economy.
For those of us who follow politics, we’re used to commentators referring to the President’s low approval rating as a surprise given the U.S.'s “booming” economy. This seeming disconnect, however, should really prompt us to reconsider the measurements by which we assess the health of an economy. With a robust U.S. stock market and GDP and low unemployment figures, it’s easy to see why some think all is well. But looking at real U.S. wages, which have remained stagnant—and have, thus, in effect gone down given rising costs from inflation—a very different picture emerges. For the 1%, the economy is booming. For the rest of us, it’s hard to even know where we stand. A recent study by Porch (a home-improvement company) of blue-collar vs. white-collar workers shows how traditional categories are becoming less distinct—the study references "new-collar" workers, who require technical certifications but not college degrees. And a set of recent infographics from CreditLoan capturing the thoughts of America’s middle class as defined by the Pew Research Center shows how confused we are.
