The aim of the SDO is to monitor solar activity and see how that impacts space weather. As part of its observations, the SDO captures an image of the Sun every 12 seconds using the onboard Atmospheric Imaging Assembly, but varies those shots across 10 different wavelengths. NASA has now collected three years worth of image data from the SDO and has put together a video letting us see the Sun spin in all its glory." If you watch closely, you can see individual frames containing the Moon and Venus.

ananyo writes "With Taiwan announcing the first case of H7N9 avian flu outside mainland China, researchers have revealed how the virus may spread in China — and beyond. The projections use risk maps developed for human infection by another, well-established avian flu — H5N1. Indeed, when human cases of H7N9 are overlaid on a risk map, they appear to fall within the highest risk areas for H5N1. The map suggests that high-risk areas for H7N9 might include Shandong province (where the first case was reported 23 April) and a belt extending around the Bohai sea to Liaoning province in the north. Though there has been no evidence of sustained human-to-human spread of H7N9 so far, researchers have analyzed airline passenger data for China. Eastern China — the epicenter of the current the H7N9 outbreak — is one of the world's busiest hubs for airline traffic. From the Nature story: 'A quarter of the global population outside of China lives within two hours of an airport with a direct flight from the outbreak regions, and 70% if a single connecting flight is included.'"
An anonymous reader writes "Matter and antimatter are thought to have existed in equal amounts at the beginning of the Universe, but today the Universe appears to be composed essentially of matter. By studying subtle differences in the behavior of particles and antiparticles, experiments at the LHC are seeking to cast light on this dominance of matter over antimatter. Now the LHCb experiment has observed a preference for matter over antimatter known as CP-violation in the decay of neutral B0s particles. The results are based on the analysis of data collected by the experiment in 2011."
astroengine writes "In a galaxy, far, far away (6 billion light-years away to be precise), the most efficient star 'factory' has been discovered. Called SDSSJ1506+54, this galaxy generates a huge quantity of infrared radiation, the majority being generated by a compact region at its core. NASA's Wide-field Infrared Survey Explorer first spotted the galactic oddity and Hubble confirmed the maelstrom of stellar birthing near its core. But the most amazing thing? This galaxy is the 'greenest' factory yet discovered — it uses 100 percent of all the available hydrogen to supply the protostars, leaving no waste. 'This galaxy is remarkably efficient,' said lead scientist Jim Geach of McGill University in a NASA news release. 'It's converting its gas supply into new stars at the maximum rate thought possible.'"
MightyMait writes "A study from a team at McGill University has found Tetris to be a good treatment for lazy eye. 'Armed with a special pair of video goggles they set up an experiment that would make both eyes work as a team. Nine volunteers with amblyopia were asked to wear the goggles for an hour a day over the next two weeks while playing Tetris, the falling building block video game. The goggles allowed one eye to see only the falling objects, while the other eye could see only the blocks that accumulate on the ground in the game. For comparison, another group of nine volunteers with amblyopia wore similar goggles but had their good eye covered, and watched the whole game through only their lazy eye. At the end of the two weeks, the group who used both eyes had more improvement in their vision than the patched group (abstract).' As someone born with crossed-eyes who underwent surgery as an infant and has lived with a lazy eye his whole life (without 3-D vision), the prospect of fixing my vision by playing Tetris is an enticing one."
