(PhysOrg.com) -- Global temperatures are increasing. Sea levels are rising. Ice sheets in many areas of the world are retreating. Yet there`s something peculiar going on in the oceans around Antarctica: even as global air and ocean temperatures march upward, the extent of the sea ice around the southern continent isn`t decreasing. In fact, it's increasing. http://www.physorg.com/news171129293.html Space & Earth Wed, 02 Sep 2009 17:10:06 EST news171129293 (PhysOrg.com) -- ESO has released a striking new image of a nearby galaxy that many astronomers think closely resembles our own Milky Way. Though the galaxy is seen edge-on, observations of NGC 4945 suggest that this hive of stars is a spiral galaxy much like our own, with swirling, luminous arms and a bar-shaped central region. These resemblances aside, NGC 4945 has a brighter centre that likely harbours a supermassive black hole, which is devouring reams of matter and blasting energy out into space. http://www.physorg.com/news171105483.html Space & Earth Wed, 02 Sep 2009 10:30:06 EST news171105483 (PhysOrg.com) -- University of Hawaii (UH) astronomer Dr. Tomotsugu Goto and colleagues have discovered a giant galaxy surrounding the most distant supermassive black hole ever found. The galaxy, so distant that it is seen as it was 12.8 billion years ago, is as large as the Milky Way galaxy and harbours a supermassive black hole that contains at least a billion times as much matter as our Sun. The scientists set out their results in a paper in the journal Monthly Notices of the Royal Astronomical Society later this month. http://www.physorg.com/news171105318.html Space & Earth Wed, 02 Sep 2009 10:15:45 EST news171105318 A new mathematical tool from Dr. Eran Halperin of TAU's Blavatnik School of Computer Science aims to protect genetic privacy while giving genomic data to researchers. http://www.physorg.com/news170937537.html Medicine & Health Mon, 31 Aug 2009 11:39:30 EST news170937537 (AP) -- This week's indictment of a hacker believed responsible for the biggest retail-store data breaches in U.S. history doesn't necessarily make shoppers safer from having their credit card numbers plundered. http://www.physorg.com/news169835746.html Technology Tue, 18 Aug 2009 17:36:57 EST news169835746 Imagine Earth without an atmosphere - without clouds, wind or air.

The discovery provides important new information about the mysterious workings of the powerful "engines" in the centers of innumerable galaxies throughout the Universe. http://www.physorg.com/news165763462.html Space & Earth Thu, 02 Jul 2009 14:24:43 EST news165763462 This new guide for astronomers, known as the APEX Telescope Large Area Survey of the Galaxy (ATLASGAL) shows the Milky Way in submillimetre-wavelength light (between infrared light and radio waves). Images of the cosmos at these wavelengths are vital for studying the birthplaces of new stars and the structure of the crowded galactic core. http://www.physorg.com/news165669952.html Space & Earth Wed, 01 Jul 2009 12:27:58 EST news165669952 Astronomers Karl Gebhardt of The University of Texas at Austin and Jens Thomas of the Max Planck Institute for Extraterrestrial Physics have used new computer modeling techniques to discover that the black hole at the heart of M87, one the largest nearby giant galaxies, is two to three times more massive than previously thought. http://www.physorg.com/news163781722.html Space & Earth Tue, 09 Jun 2009 15:56:18 EST news163781722 The massive Arches Cluster is a rather peculiar star cluster. It is located 25 000 light-years away towards the constellation of Sagittarius (the Archer), and contains about a thousand young, massive stars, less than 2.5 million years old [1]. It is an ideal laboratory to study how massive stars are born in extreme conditions as it is close to the centre of our Milky Way, where it experiences huge opposing forces from the stars, gas and the supermassive black hole that reside there. The Arches Cluster is ten times heavier than typical young star clusters scattered throughout our Milky Way and is enriched with chemical elements heavier than helium. http://www.physorg.com/news163329933.html Space & Earth Thu, 04 Jun 2009 10:27:01 EST news163329933 NASA's Chandra X-ray Observatory has found a cosmic "ghost" lurking around a distant supermassive black hole.

Nearly two-thirds of Earth's ozone is gone -- not just over the poles, but everywhere. The infamous ozone hole over Antarctica, first discovered in the 1980s, is a year-round fixture, with a twin over the North Pole. The ultraviolet (UV) radiation falling on mid-latitude cities like Washington, D.C., is strong enough to cause sunburn in just five minutes. DNA-mutating UV radiation is up 650 percent, with likely harmful effects on plants, animals and human skin cancer rates. http://www.physorg.com/news156686815.html Space & Earth Thu, 19 Mar 2009 13:07:28 EST news156686815 An international team of astrophysicists using telescopes on the ground and in space have uncovered surprising changes in radiation emitted by an active galaxy. The picture that emerges from these first-ever simultaneous observations with optical, X-ray and new-generation gamma-ray telescopes is much more complex than scientists expected and challenges current theories of how the radiation is generated. http://www.physorg.com/news156613697.html Space & Earth Wed, 18 Mar 2009 16:49:17 EST news156613697 On Friday, March 6, 2009, for the first time ever, a North Atlantic right whale that had been severely entangled in fishing gear, was administered a sedation mixture that made it possible for rescuers to remove 90 percent of the entanglement. http://www.physorg.com/news156001023.html Biology Wed, 11 Mar 2009 14:37:54 EST news156001023 (PhysOrg.com) -- The rotating black hole has been described as one of nature's most perfect objects. As described by the Kerr solution of Einstein's gravitational field equations, its spacetime geometry is completely characterized by only two numbers - mass and spin - and is sometimes described by the aphorism "black holes have no hair.'' http://www.physorg.com/news154627589.html Physics Mon, 23 Feb 2009 16:06:59 EST news154627589 (PhysOrg.com) -- With the greatest total energy, the fastest motions, and the highest-energy initial emissions ever before seen, a gamma-ray burst recently observed by the Fermi Gamma-ray Space Telescope is one for the record books.
