As most culturally astute people of a certain age know, 2015 is "The Future" of "Back To The Future II." "Back To The Future" was, of course, a seminal comedy in 1985 - a time when terrorists were from the Mid-East and you could do a time-travel experiment on your dog without getting protests outside the theater.

A third of the inherited risk of prostate cancer is closer to being identifiable with 23 new genetic variants associated with increased risk of the disease.

But there are a lot of factors. The total number of common genetic variants linked to prostate cancer is about 100, and testing for them can identify men with risk almost six times as high as the population average - but that is still just 1%.


Agriculture has one hell of a footprint, occupying 37.6 percent of earth’s land area, or about 0.7 hectares (1.7 acres) per person to feed our world's

How can we ensure that someone is who they say they are? How can be sure that the person in our system, both digitally speaking or physically in front of us, is who whom they claim to be?

Artificial hearts were invented at a time when progress in science couldn't come fast enough. In 1969, when they first went into human use, DDT hadn't been banned, vaccines were considered the medical highlight of the century, and the Green Revolution promoted genetic modification as the way to feed the world's poor in the future.
Data from an initial representative 938-subject sample of  a 4,800-subject colorectal cancer trial at Hvidovre Hospital, Copenhagen demonstrated that the NuQ® blood-based diagnostic platform  is able to correctly diagnose 84% of colorectal cancers, including early-stage cancers.

Just as the game Minecraft sees players build their virtual world block by block, Satya Nadella’s bid for its parent company is his first solid move in Microsoft’s new platforming strategy.

A 'less is more' approach is not only making 3-D printed parts lighter and stronger, but faster and more economical.

A new technique under development is high speed sintering (HSS). Unlike commercial 3-D printers that use lasers, HSS marks the shape of the part onto powdered plastic using heat-sensitive ink, which is then activated by an infra-red lamp to melt the powder layer by layer and so build up the 3-D part.

The researchers from the University of Sheffield have discovered they can control the density and strength of the final product by printing the ink at different shades of grey and that the best results are achieved by using less ink than is standard.

VFH and UFH portions of the radio spectrum are reserved for over the air television broadcasts and the FCC keeps plenty of space between channels to prevent interference.

But unused UHF TV spectrum could be used for fat streams of data over wireless hotspots that could stretch for miles, according to a presentation at the Association for Computing Machinery's MobiCom 2014 conference.
