4 Stranded Pilot Whales Treated at Fla.... - ABC News

Two male and three female whales were brought to Florida Atlantic University's Harbor Branch Institute after becoming stranded. Officials say one of the males had been stable Monday morning but died unexpectedly around noon.
The other whales, including one calf whose mother did not survive, show signs of inflammation and infection, but they are swimming on their own and accepting a thin fish formula fed through tubes every four hours.<br />http://abcnews.go.com/US/wireStory/stranded-pilot-whales-treated-fla-institute-17149493

Mars Rover Curiosity's Circular Marks Explained As 'Fiducials' - Huffington Post

"I talked to the engineers who specialize in computer vision, and we came up with the design for the fiducials [on Curiosity]," Leger said. "We wanted something that would be easy for either a computer program or a person to accurately pick the center of. Having that intersection in the middle makes it easier for a person -- they can zoom in on the image and click exactly on that intersection -- and [the design] also makes it easy for a computer, because it can compute the center of a circle."The circular markings are a staple of engineering that can serve two parallel purposes, Leger said: to calibrate cameras and to calibrate various mechanisms on the rover. They're a common feature in high-tech photography and robotics here on Earth, but the use of fiducials on extraterrestrial robots is relatively new. The technique started informally on the Mars Exploration Rover mission, which landed Spirit and Opportunity on the Red Planet's surface in 2004.<br />http://www.huffington!
