Russia claims its new anti-satellite weapon is only for defensive purposes against incoming enemy weapons.
With the help of a roller coaster and a 3D printed model of a full kidney, a team of medical researchers may have recently discovered why roller coasters cause people to pass kidney stones. According to Gizmodo, the Journal of the American Osteopathic Association published a study this month by Michigan State University urologist David D. Wartinger and his team of researchers which presented evidence that riding moderate-intensity roller coasters can trigger the passage of small kidney stones.
Scientists at the University of Rochester develop a process for making metal so hydrophobic that water is forcefully repelled from its surface. Since the microscopic and nanoscale pattern in the metal is etched into the surface, it won't degrade like chemical coatings.
Every corner of human endeavor has its researchers, and that includes activities that we might think are just supposed to be fun for kids, like pinewood derbies. In case you don't know, a pinewood derby where kids build a car out of a block of wood, add some nails for axles and plastic wheels and then race them head-to-head on a length of track with an elevated starting line. It's all about kids having fun with gravity and little chunks of timber.
Proving that there is still something to be learned on television these days, National Geographic Channel recently introduced a new series called Duck Quacks Don't Echo. On the first episode of this science/comedy show, host Michael Ian Black proposes the idea that a truck can be supported with a ceramic coffee mug under each wheel – yes, he says that the entire weight of a truck can be balanced on just four coffee mugs.
Our sister site keeps up with the plainly-visible automated machines that are precursors to The Robot Apocalypse. But what about the microscopic machines that the T900s will be working with? At right in the picture above is a Top Fuel dragster. To the left is a nanodragster; the red guys in the foreground are the front wheels, and the chassis runs to the rear axle and wheels.
