Good Morning,

Japan's public broadcasting network is planning to unveil their Super Hi-Vision television technology, which has 16 times the resolution of current HD technology, during the London Olympics. Check out the details in the first article.

Until Next Time,
Erin

Japan displays super high-definition TV

TOKYO - Japan's public broadcasting network says new television technology will offer viewers a picture with 16 times the resolution currently available on HDTVs. Nippon Housou Kyoukai demonstrated its pioneer technology, dubbed Super Hi-Vision, on the world's largest plasma TV, a 145-inch screen made by Panasonic, The Sydney Morning Herald reported Wednesday. The technology will get a public test for the first time during the London Olympics, with Super Hi-Vision screens capable of displaying the 7680-by-4320 pixel images being built in Britain, the United States and Japan. "Super Hi-Vision will be a wonderful future and will be a part of daily life," said Keiichi Kubota, director general of science and technology research laboratories at NHK. Despite the Olympic trial, NHK said, the technology will not be available to the public until at least 2020. While the few existing cameras able shoot in Super Hi-Vision are extremely large and heavy, NHK said it is partnering with Japanese tech giant Hitachi to develop the world's first shoulder-mounted Super Hi-Vision camera.


Flying drone copies bat flapping

MADRID - A drone that mimics the way a bat changes its wing shape in flight could make small unmanned vehicles more agile in flight, U.S. and Spanish researchers say. "Bat wings are highly articulated, with wing skeletons very similar to those of human arms and hands," said Julian Colorado of the Polytechnic University of Madrid. "The way bats change the shape of their wings has great potential for improving the maneuverability of micro air vehicles." Colorado and colleagues in Madrid and from Brown University in Rhode Island have built a drone with an 18-inch wingspan inspired by a type of bat called the gray-headed flying fox, capable of changing the profile of its wing between the downstroke and upstroke, NewScientist.com reported Wednesday. On the downstroke a large wing surface area is required to generate lift and propulsion, but on the upstroke a large area creates drag, so a bat folds the wing inwards on the upstroke. In the "Batbot," the extension and contraction of the wing is controlled by shape-memory alloy wires that switch between two shapes when different currents are applied, pulling in to slim the wing profile on the upstroke.


'Chemical' chip could control our bodies

LINKOPING, Sweden - Researchers in Sweden say an electronic circuit based on chemistry could control and regulate the signal paths of cells in the human body. The chip is based on ion "transistors" for transport of both positive and negative ions, as well as charged biomolecules, rather than moving electrons as in conventional electronic circuits, Linkoping University reported Tuesday. The chemical chip can thus control the delivery of neurotransmitters, allowing chemical control of muscles, researchers said. "We can, for example, send out signals to muscle synapses where the signaling system may not work for some reason. We know our chip works with common signaling substances, for example acetylcholine," Magnus Berggren, a professor of organic electronics and leader of the research group, said. An advantage of chemical circuits is that the charge carrier in the circuit consists of chemical substances with various functions in the body, researchers said, opening up possibilities of treating certain physical conditions.


Clues hint at possible Jupiter moon life

MADRID - Scientists say a frozen landscape in Canada similar to that on one of Jupiter's moons offers clues for upcoming missions to search for traces of life on Europa. It is not easy to find a place on Earth where ice and sulphur are found together, as is suspected on Jupiter's moon Europa, but such a place has been found at Borup Fjord Pass in the Canadian High Arctic, researchers say. Sulphurous yellow emissions associated with arctic bacteria contrast with the whiteness of the environment at the pass, creating images similar to those captured of Jupiter's satellite. The sulphur involved in the life cycle of Arctic microorganisms has some characteristics that could help detect biological remains on Europa, researchers said. "We have discovered that elemental sulphur (S) can contain morphological, mineralogical and organic 'biosignatures' linked to bacterial activity," Damhnait Gleeson of the Centro de Astrobiologia in Spain said. "If they are found on Europa, this would suggest the possible presence of microorganisms," he said in a release from the Spanish Foundation for Science and Technology. "There is much evidence of bacterial activity," Gleeson said of the Canadian site. In Europa's icy crust, or the ocean or lakes supposedly beneath it, there could be similar microbial communities that use sulphur as their source of energy, he said.
