(PhysOrg.com) -- The first phase of a star's formation are thought to begin deep inside a natal cloud of gas and dust. In the earliest stages, material coalesces under the influence of gravity into so-called "dense cores," which, because they absorb optical light, are sometimes seen in the sky as black shapes against a background of stars or nebulosity. http://www.physorg.com/news179153495.html Space & Earth Fri, 04 Dec 2009 13:40:01 EST news179153495 Intervals of regional warmth and cold in the past are linked to the El Niņo phenomenon and the so-called "North Atlantic Oscillation" in the Northern hemisphere's jet stream, according to a team of climate scientists. These linkages may be important in assessing the regional effects of future climate change. http://www.physorg.com/news178459644.html Space & Earth Thu, 26 Nov 2009 14:10:05 EST news178459644 A team led by scientists at The Scripps Research Institute have discovered a direct link between insulin -a hormone long associated with metabolism and metabolic disorders such as diabetes -and core body temperature. While much research has been conducted on insulin since its discovery in the 1920s, this is the first time the hormone has been connected to the fundamental process of temperature regulation. http://www.physorg.com/news177861868.html Medicine & Health Thu, 19 Nov 2009 14:20:01 EST news177861868 (PhysOrg.com) -- A new study of Antarctica's past climate reveals that temperatures during the warm periods between ice ages (interglacials) may have been higher than previously thought. The latest analysis of ice core records suggests that Antarctic temperatures may have been up to 6°C warmer than the present day. http://www.physorg.com/news177773495.html Space & Earth Wed, 18 Nov 2009 13:32:16 EST news177773495 An upgrade to a Cray XT5 high-performance computing system deployed by the Department of Energy has made the "Jaguar" supercomputer the world's fastest. Located at Oak Ridge National Laboratory, Jaguar is the scientific research community's most powerful computational tool for exploring solutions to some of today's most difficult problems. The upgrade, funded with $19.9 million under the Recovery Act, will enable scientific simulations for exploring solutions to climate change and the development of new energy technologies. http://www.physorg.com/news177608722.html Electronics Mon, 16 Nov 2009 16:30:02 EST news177608722 Long-term variations in volcanism help explain the birth, evolution and death of striking geological features called oceanic core complexes on the ocean floor, says geologist Dr Bram Murton of the National Oceanography Centre, Southampton. http://www.physorg.com/news177243136.html Space & Earth Thu, 12 Nov 2009 10:30:02 EST news177243136 (PhysOrg.com) -- The kelp forests off southern California are considered to be some of the most diverse and productive ecosystems on the planet, yet a new study indicates that today's kelp beds are less extensive and lush than those in the recent past. http://www.physorg.com/news177095541.html Biology Tue, 10 Nov 2009 17:40:02 EST news177095541 (PhysOrg.com) -- Researchers at Purdue University have discovered a new approach for repairing damaged nerve fibers in spinal cord injuries using nano-spheres that could be injected into the blood shortly after an accident. http://www.physorg.com/news176908863.html Nanotechnology Sun, 08 Nov 2009 13:22:11 EST news176908863 The seriousness of current global warming is underlined by a reconstruction of climate at Maxwell Bay in the South Shetland Islands of the Antarctic Peninsula over approximately the last 14,000 years, which appears to show that the current warming and widespread loss of glacial ice are unprecedented. http://www.physorg.com/news176727651.html Space & Earth Fri, 06 Nov 2009 11:30:07 EST news176727651 (PhysOrg.com) -- An unusual supernova rediscovered in seven-year-old data may be the first example of a new type of exploding star, possibly from a binary star system where helium flows from one white dwarf onto another and detonates in a thermonuclear explosion. http://www.physorg.com/news176653360.html Space & Earth Thu, 05 Nov 2009 14:33:57 EST news176653360 Researchers spent two months this summer high in the Peruvian Andes and brought back two cores, the longest ever drilled from ice fields in the tropics. http://www.physorg.com/news176399362.html Space & Earth Mon, 02 Nov 2009 16:00:24 EST news176399362 The diversity of colours, shapes, and sizes of planetary nebulae make them fascinating objects.

Today, the largest island in the world is covered with ice 1.6 miles thick. Even so, Greenland has become a hot spot for climate scientists. Why? Because tiny bubbles trapped in the ice layers may help resolve a fundamental question about global warming: how fast and how much will ice sheets melt? http://www.physorg.com/news175191286.html Space & Earth Mon, 19 Oct 2009 17:30:13 EST news175191286 An analysis of sediment cores indicates that biological and chemical changes occurring at a remote Arctic lake are unprecedented over the past 200,000 years and likely are the result of human-caused climate change, according to a new study led by the University of Colorado at Boulder. http://www.physorg.com/news175188684.html Space & Earth Mon, 19 Oct 2009 17:20:02 EST news175188684 (PhysOrg.com) -- At the IDF event, in Santa Clara, California, Intel announced the debut of their newest System-on-Chip (SoC), the Intel Atom processor CE4100.

They are learning about sources of nitrogen and how this element changes as it loops from the nonliving, such as the atmosphere, soil or water, to the living, whether plants or animals. Scientists have determined that humans are disrupting the nitrogen cycle by altering the amount of nitrogen that is stored in the biosphere. http://www.physorg.com/news163344321.html Space & Earth Thu, 04 Jun 2009 14:28:56 EST news163344321 Employees at the U.S. Department of Energy's Idaho National Laboratory recently reached an important milestone in developing the nation's next generation of nuclear reactors by the completion of the first of six planned Advanced Graphite Capsule (AGC) tests. http://www.physorg.com/news163091281.html Technology Mon, 01 Jun 2009 16:08:26 EST news163091281
