I guess the idea works, but there’s one little snag.

Putting solar panels into our roads isn’t the craziest idea, but we may as well admit that it poses some unique challenges. For instance, people may want to walk away with pieces of it. That’s what happened in China, anyway, just five days after authorities opened up what they claim is the world’s first solar panel-paved highway.

As reported by the Qilu Evening News (and noted by TechNode), the experimental kilometer-long stretch of road in Shandong is covered in more than 10,000 solar panels, sandwiched between an insulating layer on the bottom and a durable, transparent one on top — less than 3 cm thick all told. There are coils that can charge electric cars as they drive over it, and the system can even warm up in order to melt snow and ice. It opened to use on December 28.

Unfortunately, during an inspection on the morning of January 2, officials found a narrow piece missing, neatly cut. About 6 inches wide and 6 feet long, the piece didn’t appear to have detached on its own — suggesting someone stole it. But why?

The robots, with man-made “hands and eyes”, could assemble different types of deadly explosives including artillery shells, bombs and rockets, he said. They could also make more sophisticated ammunition such as guided bombs, equipped with computer chips and sensors, that could carry out precision strikes.

Robots could treble China’s bomb and shell production capacity in less than a decade according to a senior scientist involved in a programme that is using artificial intelligence to boost the productivity of ammunition factories.

Xu Zhigang, a researcher with the Chinese Academy of Sciences’ Shenyang Institute of Automation and a lead scientist with China’s “high-level weapon system intelligent manufacturing programme”, told the South China Morning Post last Wednesday that about a quarter of the country’s ammunition factories had replaced many workers with “smart machines” or begun to do so.

TransAstra Corporation recently completed an in-depth study of how to use resources from near Earth objects to facilitate space exploration and settlement.

The 82-page report, “Stepping Stones: Economic Analysis of Space Transportation Supplied From NEO Resources,” was funded with a $100,000 grant from NASA’s Innovative Advanced Concepts (NIAC) program.

“The Stepping Stones economic analysis of space transportation supplied from near-Earth object (NEO) resources demonstrates the potential to break the tyranny of increasing space transportation costs created by dependence on Earth-based resources, particularly propellant,” the report states.

Usually, when we’ve referred to Crispr, we’ve really meant Crispr/Cas9—a riboprotein complex composed of a short strand of RNA and an efficient DNA-cutting enzyme. It did for biology and medicine what the Model T did for manufacturing and transportation; democratizing access to a revolutionary technology and disrupting the status quo in the process. Crispr has already been used to treat cancer in humans, and it could be in clinical trials to cure genetic diseases like sickle cell anemia and beta thalassemia as soon as next year.

But like the Model T, Crispr Classic is somewhat clunky, unreliable, and a bit dangerous. It can’t bind to just any place in the genome. It sometimes cuts in the wrong places. And it has no off-switch. If the Model T was prone to overheating, Crispr Classic is prone to overeating.

Even with these limitations, Crispr Classic will continue to be a workhorse for science in 2018 and beyond. But this year, newer, flashier gene editing tools began rolling off the production line, promising to outshine their first-generation cousin. So if you were just getting your head around Crispr, buckle up. Because gene-editing 2.0 is here.

Virgin Hyperloop One set a test speed record of nearly 240 miles per hour during its third phase of testing at its site in Nevada.

The company also tested a new airlock which helped transition test pods between atmospheric and vacuum conditions during a test campaign which was completed on December 15, 2017.

The tests were conducted in a tube depressurized down to the equivalent air pressure experienced at 200,000 feet above sea level.

A Virgin Hyperloop One pod quickly lifts above the track using magnetic levitation and glides at airline speeds for long distances due to ultra-low aerodynamic drag.
