You’re traveling more than 1,000 miles across the barren snowscape of Antarctica. Along the way, many crevasses lie hidden between you and your quest to resupply the hungry scientists at the Amundsen-Scott South Pole Station. The good news is you can detect these deathtraps with a radar arm. The bad news is it only gives you approximately four seconds of warning before you and your tracked vehicle, which weighs several tons, plummet to a dark and silent tomb. If only there were a robot that could map crevasses ahead of such expeditions. Preferably one with an adorable yet mildly ferocious name.
Meet the Yeti. This four-wheel-drive rover drags a ground-penetrating radar arm capable of logging information that tells scientists what lies—or more importantly, doesn’t lie—below. At just 180 pounds, the bot crosses snow-covered crevasses like it ain’t no thing. (Since people don’t wander around on foot down there, the real danger is the heavy tracked vehicles breaking through the snow bridges.) It functions at temperatures around -20 degrees Fahrenheit. In short, Yeti is an awesome little minion redrawing the boundaries of hazard georeferencing.
Most of us don’t have to think about such things, but doing science on the bottom of the world is a tricky endeavor. In addition to dangerous weather conditions and 30-foot-wide trapdoors in the ice, the logistics of assembling personnel, equipment, and supplies at the South Pole is nothing short of extraordinary.
“The focus of this effort was to support the actual operations and logistics side of the Polar Program,” James Lever, mechanical engineer and specialist in over-snow mobility for the U.S. Army’s Cold Regions Research and Engineering Laboratory, told me. (I bet you never heard a kindergartener say she wants to grow up to specialize in over-snow mobility.) Lever and his co-principal investigator professor Laura Ray published their findings this month in the Journal of Field Robotics. “Whether you have researchers in Antarctica or Greenland, you have to keep people safe and comfortable. You’re a long way from everything else and so it’s expensive to do science there.”
The little Yeti—and its predecessor, the solar-powered Cool Robot—have found support from the operations and science arms of the National Science Foundation as well as NASA’s Jet Propulsion Laboratory—after all, rover work on Earth’s poles isn’t so different from rover work on Mars or other celestial bodies. And the lessons we learn from tweaking Yeti may one day help us in space. For instance, one of the paper’s coauthors from the Thayer School of Engineering at Dartmouth College is developing an algorithm to detect characteristic moments just before Yeti gets stuck. If the algorithm can prevent the bot from getting into jams in the first place, it saves Lever and his colleagues an annoying trip out into the white. For NASA on the other hand, an immobilized rover is a really expensive bummer. For as Lever put it, “They don’t get theirs back.”
Sweden Recognizes Palestinian State; Israel Upset 2014 10 31
Sweden on Thursday became the biggest Western European country to recognize a Palestinian state, prompting a strong protest from Israel, which swiftly withdrew its ambassador from Stockholm.
The move by Sweden’s new left-leaning government reflects growing international impatience with Israel’s nearly half-century control of the West Bank, east Jerusalem and its blockade of the Gaza Strip. It also comes during increased ...
Fed-Backed Study: How to Brainwash Public into Fearing “Climate Change” Like Ebola 2014 10 31
$84K study seeks ways to make public fear "climate change and overpopulation"
The National Science Foundation is funding a study to determine how to brainwash the public into fearing “climate change and overpopulation” as if they were Ebola.
The NSF awarded an $84,000 grant to researchers at the State University of New York at Buffalo yesterday to figure out how to make ...

“If you do not specify and confront real issues, what you say will surely obscure them. If you do not alarm anyone morally, you yourself remain morally asleep. If you do not embody controversy, what you say will be an acceptance of the drift of the coming hell.” C Wright Mills.

Google’s New Computer With Human-Like Learning Abilities Will Program Itself 2014 10 30
In college, it wasn’t rare to hear a verbal battle regarding artificial intelligence erupt between my friends studying neuroscience and my friends studying computer science.
One rather outrageous fellow would mention the possibility of a computer takeover, and off they went. The neuroscience-savvy would awe at the potential of such hybrid technology as the CS majors argued we have nothing to ...
