While it is clear that massive destruction of tropical rainforests poses a serious threat to the incredibly rich biodiversity found on Earth, other hazards are not so explicit. An international group of prominent scientists argue in the November 17th issue of the journal Current Biology, a Cell Press publication, that the most promising new strategy to protect our planet may not live up to its full potential. The group calls for global implementation of careful and sensible protective policies. http://www.physorg.com/news177599405.html Biology Mon, 16 Nov 2009 13:20:01 EST news177599405 (PhysOrg.com) -- The nucleus of an active galaxy, an AGN, contains a massive black hole that is vigorously accreting material. In the process it typically ejects jets of particles and radiates brightly at many wavelengths, in particular at X-ray wavelengths. http://www.physorg.com/news177337799.html Space & Earth Fri, 13 Nov 2009 12:30:51 EST news177337799 (PhysOrg.com) -- Astrophysicists at the University of Warwick and Kiel University have discovered two earth sized bodies with oxygen rich atmospheres - however there is a bit of a disappointing snag for anyone looking for a potential home for alien life, or even a future home for ourselves, as they are not planets but are actually two unusual white dwarf stars. http://www.physorg.com/news177258394.html Space & Earth Thu, 12 Nov 2009 14:27:33 EST news177258394 (PhysOrg.com) -- Astronomers have published the discovery of the farthest known object in the cosmos: a star that exploded when the universe was only 630 million years old -- only 4.6% of its current age. Light from this cataclysm had been traveling towards us for about 13 billion years, finally arriving here last April 23. http://www.physorg.com/news176733128.html Space & Earth Fri, 06 Nov 2009 12:50:01 EST news176733128 While most people were turning their clocks backward over the weekend, Microsoft research chief Craig Mundie was moving his forward, five to 10 years into the future. http://www.physorg.com/news176660694.html Technology Thu, 05 Nov 2009 16:50:02 EST news176660694 The most probable place to find intelligent life in the galaxy is around stars very similar to our sun, a new study has found. http://www.physorg.com/news176661214.html Space & Earth Thu, 05 Nov 2009 16:50:01 EST news176661214 During the last ice age, massive glaciers covered much of our planet. However, a region of Alaska, Siberia and the Canadian Yukon remained ice-free. This region, known as Beringia, supported unique organisms and was an important haven for evolution. Now, scientists may have uncovered how Beringia supported such diversity at a time when conditions for life were harsh. http://www.physorg.com/news176056791.html Space & Earth Thu, 29 Oct 2009 17:50:03 EST news176056791 A team of researchers led by a Case Western Reserve University physicist is planning the world's largest, most sensitive experiment to catch the stuff of dark matter, stuff that's proved way beyond invisible. http://www.physorg.com/news176041529.html Physics Thu, 29 Oct 2009 14:10:02 EST news176041529 (PhysOrg.com) -- The most distant object ever discovered is described in this week's edition of the science journal Nature. Two international teams of astronomers report their observations of a gamma-ray burst from a star that died when the Universe was 640 million years old, or less than 5 percent of its present age. http://www.physorg.com/news175969717.html Space & Earth Wed, 28 Oct 2009 17:30:09 EST news175969717 (PhysOrg.com) -- The Orion Nebula is one of the most beautiful sights of the winter night sky, its gas and dust glowing from the intense ultraviolet radiation of a cluster of massive young stars. http://www.physorg.com/news175507575.html Space & Earth Fri, 23 Oct 2009 09:07:12 EST news175507575 (PhysOrg.com) -- Sidekick users have been without some of their services for days, and have just been told by the company, T-Mobile, that for some users their data may be lost forever due to a server error at Microsoft subsidiary, Danger. http://www.physorg.com/news174545918.html Electronics Mon, 12 Oct 2009 06:00:32 EST news174545918 (PhysOrg.com) -- Supernovae, the explosive deaths of massive stars, disburse into space all of the chemical elements that were spawned inside the progenitor stars. http://www.physorg.com/news172501824.html Space & Earth Fri, 18 Sep 2009 15:00:01 EST news172501824 (PhysOrg.com) -- Our understanding of star formation leans heavily on observations of stars like the sun, namely, those that are modest in mass and that are born and evolve at a relatively leisurely pace. http://www.physorg.com/news172237617.html Space & Earth Tue, 15 Sep 2009 12:50:14 EST news172237617 The Central Molecular Zone (CMZ) of our galaxy is a giant complex of molecular gas and dust situated in the innermost 700 light-years of the Milky Way. Although the galaxy is over 100,000 light-years in size, nearly 10% of all of its molecular gas lies in the CMZ. Astronomers know that regions of dense gas and dust tend to produce new stars as the material coalesces and heats up under the influence of gravity. http://www.physorg.com/news170687664.html Space & Earth Fri, 28 Aug 2009 14:15:25 EST news170687664 (PhysOrg.com) -- An international team of researchers has debunked one of astronomy's long held beliefs about how stars are formed, using a set of galaxies found with CSIRO`s Parkes radio telescope. http://www.physorg.com/news170429814.html Space & Earth Tue, 25 Aug 2009 14:37:35 EST news170429814 (PhysOrg.com) -- For decades, astronomers have gone about their business of studying the cosmos with the assumption that stars of certain sizes form in certain quantities. Like grocery stores selling melons alone, and blueberries in bags of dozens or more, the universe was thought to create stars in specific bundles. In other words, the proportion of small to big stars was thought to be fixed. For every star 20 or more times as massive as the sun, for example, there should be 500 stars with the sun's mass or less. http://www.physorg.com/news169924281.html Space & Earth Wed, 19 Aug 2009 18:12:23 EST news169924281 The existence of black holes is one of the most amazing and bizarre predictions of Einstein's theory of gravity. Despite his original misgivings about their reality, massive black hole holes are today believed to lie at the centers of most galaxies and to be the inevitable consequence of the demise of massive stars. http://www.physorg.com/news169819669.html Space & Earth Tue, 18 Aug 2009 13:08:36 EST news169819669 University of California, San Diego computer scientists have created software that they hope will lead to data centers that logically function as single, plug-and-play networks that will scale to the massive scale of modern data center networks. The software system -- PortLand -- is a fault-tolerant, layer 2 data center network fabric capable of scaling to 100,000 nodes and beyond. http://www.physorg.com/news169753059.html Technology Mon, 17 Aug 2009 18:38:47 EST news169753059 (AP) -- Repairs to two small helium leaks in the world's largest atom smasher will delay the restart of the giant machine another month until November, a spokesman for the operator said Thursday. http://www.physorg.com/news168180155.html Physics Thu, 30 Jul 2009 13:43:42 EST news168180155 (PhysOrg.com) -- A team of researchers working with data from ESA`s Integral gamma-ray observatory has disproved theories that some form of dark matter explains mysterious radiation in the Milky Way. http://www.physorg.com/news167493073.html Space & Earth Wed, 22 Jul 2009 15:40:01 EST news167493073 The potential for a huge Pacific Ocean tsunami on the West Coast of America may be greater than previously thought, according to a new study of geological evidence along the Gulf of Alaska coast. http://www.physorg.com/news167303056.html Space & Earth Mon, 20 Jul 2009 10:04:45 EST news167303056 This beautiful image gives a new look at Stephan's Quintet, a compact group of galaxies discovered about 130 years ago and located about 280 million light years from Earth. The curved, light blue ridge running down the center of the image shows X-ray data from the Chandra X-ray Observatory. http://www.physorg.com/news166371617.html Space & Earth Thu, 09 Jul 2009 15:21:24 EST news166371617 A new class of black hole, more than 500 times the mass of the Sun, has been discovered by an international team of astronomers. http://www.physorg.com/news165675129.html Space & Earth Wed, 01 Jul 2009 13:52:39 EST news165675129 A new image from NASA's Chandra X-ray Observatory shows a supernova remnant with a different look. This object, known as SNR 0104-72.3 (SNR 0104 for short), is in the Small Magellanic Cloud, a small neighboring galaxy to the Milky Way. Astronomers think that SNR 0104 is the remains of a so-called Type Ia supernova caused by the thermonuclear explosion of a white dwarf. http://www.physorg.com/news163771339.html Space & Earth Tue, 09 Jun 2009 13:03:09 EST news163771339 In a controversial new paper in the journal Nature, astronomers from Queen's University Belfast have proposed a new physical interpretation of a supernova discovered on 7th November 2008. http://www.physorg.com/news163760815.html Space & Earth Tue, 09 Jun 2009 10:07:23 EST news163760815 The colossal stellar explosions called supernovae come in many kinds and flavours. Some of them are produced when a massive star reaches the end of its life in a sudden gravitational collapse. Astronomers have just found one of these explosions that defies the current classification scheme. The results of this research have been published in Nature, and Calar Alto has contributed to this discovery. http://www.physorg.com/news163397750.html Space & Earth Fri, 05 Jun 2009 05:16:41 EST news163397750 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 Two decades ago a renowned statistician described a computer data set of 1 billion bytes as "huge" and 10 trillion bytes as "ridiculous." http://www.physorg.com/news161534202.html Technology Thu, 14 May 2009 15:37:47 EST news161534202 (AP) -- Google Inc. is about to add more features to its already dominant Internet search engine - and some of the changes could give Web surfers less reason to click through to other sites. That scenario might upset the creators of the material highlighted in Google's results. http://www.physorg.com/news161364058.html Technology Wed, 13 May 2009 05:00:08 EST news161364058 Is there a bit of Bernie in you?
