Snake-inspired robot uses kirigami to move

Wed, 21 Feb 18 00:04:50 -0800

Harvard researchers developed a soft robot inspired by snakeskin that crawls without any rigid components. The soft robotic scales are made using kirigami -- an ancient Japanese paper craft that relies on cuts, rather than origami folds, to change the properties of a material. As the robot stretches, the flat kirigami surface is transformed into a 3-D-textured surface, which grips the ground just like snakeskin.

This new information provides evidence to help astronomers better understand the process by which such planets form.

NASA seeks the gold in Winter Olympics snow

Thu, 08 Feb 18 00:15:40 -0800

NASA engineer Manuel Vega can see one of the Olympic ski jump towers from the rooftop of the South Korean weather office where he is stationed. Vega is not watching skiers take flight, preparing for the 2018 PyeongChang Winter Olympics and Paralympic games. Instead, he's inspecting the SUV-sized radar beside him. The instrument is one of 11 NASA instruments specially transported to the Olympics to measure the quantity and type of snow falling on the slopes, tracks and halfpipes.

WSU researchers build alien ocean to test NASA outer space submarine

Wed, 07 Feb 18 00:06:30 -0800

Building a submarine gets tricky when the temperature drops to -300 Fahrenheit and the ocean is made of methane and ethane. Washington State University researchers are working with NASA to determine how a submarine might work on Titan, the largest of Saturn's many moons and the second largest in the solar system. The space agency plans to launch a real submarine into Titan seas in the next 20 years.

In 2016, a team of researchers led by EU-funded astronomer Michael Gillon at the University of Liege, Belgium, discovered three temperate Earth-sized planets orbiting TRAPPIST-1, an ultra-cool dwarf star just 40 light years from Earth. A few months later, Gillon surprised the world with the discovery of a whole planetary system made of a total of seven planets around this star. A set of new studies reveals today the nature and composition of the planets, shedding light on their potential habitability.
