No Earth impact in 2040: NASA releases workshop data and findings on asteroid 2011 AG5 (June 15, 2012) -- Researchers anticipate that asteroid 2011 AG5, discovered in January 2011, will fly safely past and not impact Earth in 2040. Observations to date indicate there is a slight chance that AG5 could impact Earth in 2040. Experts are now confident that in the next four years, analysis of space and ground-based observations will show the likelihood of 2011 AG5 missing Earth to be greater than 99 percent. ... > full story
Data from NASA's Voyager 1 point to interstellar future (June 15, 2012) -- Data from NASA's Voyager 1 spacecraft indicate that the venerable deep-space explorer has encountered a region in space where the intensity of charged particles from beyond our solar system has markedly increased. Voyager scientists looking at this rapid rise draw closer to an inevitable but historic conclusion -- that humanity's first emissary to interstellar space is on the edge of our solar system. ... > full story
Test of spare wheel puts NASA's Mars Odysse orbiter on path to recovery (June 15, 2012) -- In a step toward returning NASA's Mars Odyssey orbiter to full service, mission controllers have tested a spare reaction wheel on the spacecraft for potential use with two other reaction wheels in adjusting and maintaining the spacecraft's orientation. ... > full story
Dawn easing into its final science orbit (June 15, 2012) -- After successfully completing nearly five months scrutinizing the giant asteroid Vesta at its lowest orbit altitude, NASA's Dawn spacecraft will begin its final major science data-gathering phase at Vesta on June 15, at an average altitude of 420 miles (680 kilometers) above the surface. ... > full story
First flight instrument delivered for James Webb Space Telescope (June 15, 2012) -- The first of four instruments to fly aboard NASA's James Webb Space Telescope (Webb) has been delivered to NASA. The Mid-Infrared Instrument (MIRI) will allow scientists to study cold and distant objects in greater detail than ever before. ... > full story
Neutrons escaping to a parallel world? (June 15, 2012) -- In a new paper, researchers hypothesize the existence of mirror particles to explain the anomalous loss of neutrons observed experimentally. The existence of such mirror matter had been suggested in various scientific contexts some time ago, including the search for suitable dark matter candidates. ... > full story
Physicists predict success of movies at the box office based solely on advertising costs (June 15, 2012) -- A group of Japanese scientists have surprised themselves by being able to predict the success or failure of blockbuster movies at the box office using a set of mathematical models. The researchers used the effects of advertising and word-of-mouth communication to create a model that turned out to be successful in predicting how each movie fared once it hit the silver screen. The only data the researchers needed to put into the model were the daily advertisement costs of 25 movies that appeared in Japanese cinemas. ... > full story
New solar active region spitting out flares (June 14, 2012) -- An active region on the sun, numbered AR 1504, rotated into view over the left side of the sun on June 10, 2012. The region fired off two M-class flares and two coronal mass ejections (CMEs) on June 13 and June 14, 2012. ... > full story
Catching some rays: Organic solar cells make a leap forward (June 14, 2012) -- Organic solar cells are becoming more efficient thanks to a new set of discoveries that alter their behaviors at the electronic level. ... > full story
Engineers perfecting carbon nanotubes for highly energy-efficient computing (June 14, 2012) -- Carbon nanotubes represent a significant departure from traditional silicon technologies and offer a promising path to solving the challenge of energy efficiency in computer circuits, but they aren't without challenges. Now, engineers have found ways around the challenges to produce the first full-wafer digital logic structures based on carbon nanotubes. ... > full story
Switchable nano magnets may revolutionize data storage: Magnetism of individual molecules switched (June 14, 2012) -- Using individual molecules instead of electronic or magnetic memory cells would revolutionize data storage technology, as molecular memories could be thousand-fold smaller. Scientists have now taken a big step toward developing such molecular data storage. ... > full story
Optical displays from water and air (June 14, 2012) -- For many years, scientists have been pursuing ways to mimic the perplexing capability of the lotus leaf to repel water. Lotus leaves hate water so much that droplets effortlessly roll off the surface, keeping it clean from dirt. Now an international team of researchers have come up with an entirely new concept of writing and displaying information on surfaces using simply water. They exploit the unique way a trapped layer of air behaves on a lotus-inspired dual-structured water-repelling surface immersed under water. ... > full story
