Golden Horde introduces swarm tactics to guided munitions—but it also lets the weapons make real decisions.

CHINA’S increasingly belligerent behaviour on the world stage poses a major challenge for NATO, with Taiwan a looming flashpoint, a new report has warned.

The PLA Navy may be poised to overcome a technological and tactical defect that has plagued it since its founding.

Here’s What You Need To Remember: American submariners long lampooned Soviet and Chinese nuclear boats for being noisy and easy to detect. PLA Navy boats remained backward long after the Cold War. Ultraquiet propulsion, though, would put an end to unquestioned U.S. acoustic supremacy, opening up new operational and strategic vistas before the PLA Navy while ushering in a deadlier phase of U.S.-China strategic competition.

A second fan on the rear then pushes air behind the craft, driving it forward. Rudders behind this thrust fan turn the craft. It may be a hovercraft at its core, but like regular cars on the street, it has got headlights, navigation lamps, cockpit lights, as well as a flux capacitor — that’s the coloured lights around the perimeter. The hovercraft took a total of four-and-a-half years to build.

So, piloting the hovercraft feels like driving a car that’s constantly sliding around on ice. You got your foot pedal and steering wheel and it feels like you’re in a car, but you are just sliding around every way with no friction.

As cool as it is ingenious, this custom-built hovercraft by college student Ken Chung just might be the world’s fastest, courtesy of its jet turbine engine. Continue reading for the video — courtesy of reader James.

“We believe we are uncovering the tip of the iceberg in terms of distant SGRBs,” said Kerry Paterson, the study’s first author. “That motivates us to further study past events and intensely examine future ones.”

The origin of our teeth goes back more than 400 million years back in time, to the period when strange armored fish first developed jaws and began to catch live prey. We are the descendants of these fish, as are all the other 60,000 living species of jawed vertebrates — sharks, bony fish, amphibians, reptiles, birds and mammals. An international team of scientists led by Uppsala University (Sweden), in collaboration with the ESRF, the European Synchrotron (France), the brightest X-ray source, has digitally ‘dissected’, for the first time, the most primitive jawed fish fossils with teeth found near Prague more than 100 years ago. The results, published recently in Science, show that their teeth have surprisingly modern features.

Teeth in current jawed vertebrates reveal some consistent patterns: for example, new teeth usually develop on the inner side of the old ones and then move outwards to replace them (in humans this pattern has been modified so that new teeth develop below the old ones, deep inside the jawbone). There are, however, several differences between bony fish (and their descendants the land animals) and sharks; for example the fact that sharks have no bones at all, their skeleton is made of cartilage, and neither the dentine scales nor the true teeth in the mouth attach to it; they simply sit in the skin. In bony fish and land animals, the teeth are always attached to jawbones. In addition, whilst sharks shed their worn-out teeth entire, simply by detaching them from the skin, bony fish and land animals shed theirs by dissolving away the tooth bases.

The consumer-electronics research arm has been quiet for years—but it’s also been busy. Its new mission: Make Google hardware as smart as Google software.
