Scientists have developed a working laboratory demonstrator of a lithium-oxygen battery which has very high energy density, is more than 90% efficient, and, to date, can be recharged more than 2000 times, showing how several of the problems holding back the development of these devices could be solved, and would enable an electric car with a battery that is a fifth the cost and a fifth the weight of those currently on the market to drive from London to Edinburgh on a single charge.
There is no question that our knowledge of brains has expanded massively in the past century. But what does all this data about brains really tell us about consciousness? Not a great deal.
In this video, Ralph Smart of Infinite Waters Diving Deep shares 10 amazing scientific ideas that he thinks will change the world.
For a whole lot of people, especially those in developing countries, science — and with it, medicine — isn’t readily available to the majority of citizens. But Manu Prakash wants to change that. Prakash, an assistant professor of bioengineering at Stanford, is the proprietor of “frugal science,” a term he coined to explain the movement toward building cheap versions of high tech tools. His endeavour aims to make medical devices both affordable and available to the masses…So in 2014 he created a paper microscope, aptly named the Foldscope, that costs only 50 cents to produce.
Lihong Wang creates the sort of medical technology you’d expect to find on the starship Enterprise. Wang, a professor of biomedical engineering at Washington University in St. Louis, has already helped develop instruments that can detect individual cancer cells in the bloodstream and oxygen consumption deep within the body. He has also created a camera that shoots at 100 billion frames a second, fast enough to freeze an object traveling at the speed of light.
Video Source: AsapSCIENCE With the recent release of the movie, Self/Less, where Ben Kingsley’s wealthy and powerful character transfers his consciousness into the body of a much younger Ryan Reynolds for more longevity, there is a natural curiosity about whether this sort of thing is even remotely plausible. The curious guys at Science Asap explore that […]
Today, predicting the direction in which technology is heading is a lot easier than it was 65 years ago. Unfortunately, these advancements don’t always have the potential to benefit mankind, sometimes the opposite is true. Is our way of life, or indeed all of humanity, at risk from these dangers?
The THRIVE Movement has received over 500 breakthrough projects in the past three years, both technological and social innovations. This excerpt from the ThriveTogether event describes the potential for Open Source and 3D printing in getting new energy technologies out to the world.
Dr. Michio Kaku takes us on a grand tour of what the future holds, giving us not only a solid sense of how the brain functions but also how these technologies will change our daily lives. He even presents a radically new way to think about “consciousness.” Kaku says that one day we might have a “smart pill” to enhance our cognition; upload our ain to a computer, neuron for neuron; send thoughts and emotions around the world on a “brain-net”; control computers and robots with our minds; push the limits of immortality, sending consciousness across the universe.
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.
