Quantum interaction: 10,000 times faster than light

By Jesse EmspakLiveScience How fast do quantum interactions happen? Faster than light, 10,000 times faster. That’s what a team of physicists led by Juan Yin at the University of Science and Technology of China in Shanghai found in an experiment involving entangled photons, or p …   Original post on nbcnews.com    Comments on reddit.com   

Blinded by the Light by Bjørn Lomborg

On March 23, a billion or more people will participate in “Earth Hour” by turning off their lights from 8:30-9:30 in the evening. The organizers say that they are providing a way to demonstrate one’s desire to “do something” about global warming, but the stark reality is that Earth Hour will increase carbon emissions.   Original post on project-syndicate.org    Comments on reddit.com   

Graphene Breakthrough – One Photon Can Be Converted Into Multiple Electrons

A new discovery by researchers at the ICFO has revealed that graphene is even more efficient at converting light into electricity than previously known. Graphene is capable of converting a single photon of light into multiple electrons able to drive electric current. The discovery is an important one for next-generation solar cells, as well as   Original post on cleantechnica.com    Comments on reddit.com   

8th century gamma ray burst irradiated the Earth, study finds

(Phys.org)—A nearby short duration gamma-ray burst may be the cause of an intense blast of high-energy radiation that hit the Earth in the 8th century, according to new research led by astronomers Valeri Hambaryan and Ralph Neuhӓuser. The two scientists, based at the Astrophysics Institute of the…   Original post on phys.org    Comments on reddit.com   

Evolution inspires more efficient solar cell design: Geometric pattern maximizes time light is trapped in solar cell

(Phys.org)—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…   Original post on phys.org    Comments on reddit.com   

UV Light Emitting Machine Disinfects Hospital Rooms In Minutes

It’s a staggering modern-day irony that the most common complication for hospital patients is acquiring an infection during their visit, affecting 1 in 20 patients in the US. It’s a problem estimated to cause millions of infections with 100,000 or so leading to death per year and a whopping $45 billion annually in hospital costs. If this isn’t bad enough, the tragedies from deadly superbugs within healthcare facilities are on the rise and will likely continue as the last lines of antibiotics fail without any new drugs moving fast enough up the pipeline to help.   Original post on singularityhub.com    Comments on reddit.com   

University of Michigan News Service – Super-fine sound beam could one day be an invisible scalpel

A carbon-nanotube-coated lens that converts light to sound can focus high-pressure sound waves to finer points than ever before. The University of Michigan engineering researchers who developed the ne   Original post on umich.edu    Comments on reddit.com   

The great rush: Government to give green light to mass exploration for shale gas – Home News – UK

More than 60 per cent of the British countryside could be exploited for shale gas, government documents show, as ministers prepare to give the go-ahead for developing the country’s most significant new energy source since North Sea oil.   Original post on independent.co.uk    Comments on reddit.com
