Robo-Worm Might Give You the Creeps
Scientists funded by the Pentagon have created a robot for the purpose of looking into hard-to-reach places, from spaces trapped beneath earthquake rubble to the private quarters of state enemies.
Scientists funded by the Pentagon have created a robot for the purpose of looking into hard-to-reach places, from spaces trapped beneath earthquake rubble to the private quarters of state enemies.
The miniature, autonomous “Meshworm” has a body of soft metallic mesh that crawls across surfaces by squeezing segments of its body like an earthworm. The robot survived multiple blows from a hammer and the stomping of a foot.
The British-based Chartered Institute for IT confirmed that the worm could be used for spying.

Your support matters…New York Daily News:
The worm was created with various flexible materials: a mesh-type tube for its body and nickel-titanium alloy for its muscle. The muscle is shape-memory material so it expands and contracts when exposed to heat, reports MIT. By sending a current through the wire, the team caused the robo-worm to move much like a real earthworm.
… Meshworm’s real-life counterpart inches along the ground by contracting and stretching their muscles throughout their bodies – a process called peristalsis. The human gastrointestinal tracts also use this process to carry food through the body.
Professor Kellar Autumn, a biomechanics specialist at Lewis and Clark College, thinks the team’s accomplishment hints toward technological developments in the near future that may affect us all. He predicts that shape-shifting synthetic muscles will appear in cars, cell phones and laptops, according to MIT. Additionally, the technology could help the medical field with implants, endoscopes and prosthetics.

Obama's only takeaway from the Syria episode was to never again seek Congressional approval for military action.
The president’s foreign policy seldom matches his anti-war rhetoric. In 2020, it’s incumbent on his opposition to offer a true alternative.
There’s a lot about our wars that we don’t know, but what we do know is enough to make a person cry.
The president's 2020 opponents would do well to watch his moves on the international front, as they could help his re-election cause.
