Mystery of rare 5-hour space explosion explained
University Park (SPX) Sep 23, 2014
Next week in St. Petersburg, Russia, scientists on an international team that includes Penn State University astronomers will present a paper that provides a simple explanation for mysterious ultra-long gamma-ray bursts - a very rare form of the most powerful explosions in the universe. "The recent discovery of ultra-long gamma-ray bursts raised questions about whether some new physics is required to explain them, but our work suggests a much simpler explanation," said David Burrows, a Penn State ... read more

Big surprises can come in small packages Astronomers using the NASA/ESA Hubble Space Telescope have found a monster lurking in a very unlikely place. New observations of the ultracompact dwarf galaxy M60-UCD1 have revealed a supermassive b ... more		Hubble Helps Find Smallest Galaxy Containing Supermassive Black Hole Astronomers using data from NASA's Hubble Space Telescope and ground observation have found an unlikely object in an improbable place - a monster black hole lurking inside one of the tiniest galaxi ... more		Three's a charm: NIST detectors reveal entangled photon triplets Researchers at the University of Waterloo in Canada have directly entangled three photons in the most technologically useful state for the first time, thanks in part to superfast, super-efficient si ... more
				Physicists teleport photon over 15 miles Professor Nicolas Gisin and his team have successfully teleported a photon over 15 miles in its quantum state. The Swiss team of scientists aimed to transport the photon into a crystal without the two touching, and they did just that. The same team were able to accomplish this in 2003, but they were only able to teleport the light a little less than four miles. The reporting of the accomplishment can be found in the latest issue of Nature Photonics. ... more		Elusive quantum transformations found near absolute zero Heat drives classical phase transitions-think solid, liquid, and gas-but much stranger things can happen when the temperature drops. If phase transitions occur at the coldest temperatures imaginable ... more

But as galaxies age and grow more massive over time, their ability to create their own stars wanes, and they are forced to add on mass by swallowing up other smaller galaxies. ... more

The confusion starts from the several uses of the word "life" in English.
