Submission + - 16th-Century Map May Provide New Clues About The Fate Of The Roanoke Colony (nytimes.com)

JoeRobe writes: Roanoke Colony (on the coast of North Carolina) disappeared sometime between 1587 and 1590, with the only clue to its fate being the word "Croatoan" carved into a wooden post. Now, as if straight out of an Indiana Jones script, new clues to the whereabouts of the lost colony may have been discovered on a 16th-century map. The British Museum has re-examined the watercolor map to find a hidden symbol under a patch, in the shape of a 4-pointed star. The star likely indicates the location of an existing or intended fort that the settlers may have retreated to after abandoning the colony. Adding to the mystery, the patch overlaying the star may have been added in order to hide it from the "spy-riddled English court."

Submission + - US Approves Two New Nuclear Reactors

JoeRobe writes: For the first time in 30 years, the US Nuclear Regulatory Commission has approved licenses to build two new nuclear reactors in Georgia. These are the first licenses to be issued since the Three Mile Island incident in 1979. The pair of facilities will cost $14 billion and produce 2.2 GW of power (able to power ~1 million homes). They will be Westinghouse AP1000 designs, which are the newest reactors approved by the NRC. These models passively cool their fuel rods using condensation and gravity, rather than electricity, preventing the possibility of another Fukushima Daiichi-type meltdown due to loss of power to cooling water pumps.

Submission + - New "Rubber Robot" able to crawl through small spa (cnn.com)

JoeRobe writes: Researchers at Harvard have developed a pneumatically-controlled rubber robot that combines undulation and quadrupedal "crawling", allowing it to maintain a low profile while moving. In a paper in published in PNAS, they describe it as "A soft robot, composed exclusively of soft materials (elastomeric polymers), which is inspired by animals (e.g., squid, starfish, worms) that do not have hard internal skeletons." The robot is solely powered by relatively low pressures (10 psi), and controlled by 5 pneumatic actuators. The research was funded by DARPA.
