Is our universe just one of many? The idea may sound a bit bizarre, but it could be a reality, scientists say.
Massive declines in coral reefs, mangrove swamps and wetlands.
The sun’s energy is virtually limitless, but harnessing its electricity with today’s single-crystal silicon solar cells is extremely expensive — 10 times pricier than coal, according to some estimates. Organic solar cells — polymer solar cells that use organic materials to absorb light and convert it into electricity — could be a solution, but current…
Scientists have long puzzled over why the surface of the sun is cooler than its corona, the outer hazy atmosphere visible during a solar eclipse. Now thanks to a five-minute observation by a small, but very high-resolution ultraviolet telescope they have some answers. Even before the July 2012 launch of the High-resolution Coronal Imager, nicknamed…
Unthinkable as it may be, humanity, every last person, could someday be wiped from the face of the Earth. We have learned to worry about asteroids and supervolcanoes, but the more-likely scenario, according to Nick Bostrom, a professor of philosophy at Oxford, is that we humans will destroy ourselves. Bostrom, who directs Oxford’s Future of…
In surprising numbers, people posted, viewed and searched for science-related topics last year — sharing news from space and undersea, commenting on new discoveries and uploading photos and video in a full-out embrace of the ability to communicate with thousands of others about global subjects in real time. The trend is, in some ways, self-fulfilling….
The search for the perfect alliance between science and technology has married quantum computing to the future of IT – the cloud. Researchers have used quantum mechanics to encrypt heavy-duty number-crunching computing, thereby removing a major obstacle in the adoption of the cloud for many enterprises – how safe is my data when it’s hosted…
