Patients with a cluster headache, which is characterized by bouts of excruciating pain usually near the eye or temple, were more likely to report being pain-free within 15 minutes of treatment with high-flow oxygen than patients who received a placebo treatment, according to a study in the December 9 issue of JAMA. http://www.physorg.com/news179513515.html Medicine & Health Tue, 08 Dec 2009 17:20:40 EST news179513515 Noted for harbouring Eta Carinae -- one of the wildest and most massive stars in our galaxy -- the impressive Carina Nebula also houses a handful of massive clusters of young stars. The youngest of these stellar families is the Trumpler 14 star cluster, which is less than one million years old -- a blink of an eye in the Universe's history. This large open cluster is located some 8000 light-years away towards the constellation of Carina (the Keel). http://www.physorg.com/news179068963.html Space & Earth Thu, 03 Dec 2009 13:23:15 EST news179068963 On Noah's Ark animals came in twos: male and female. In human bodies trillions of cells are coupled, too, and so are the molecules from which they are composed. Yet these don't come in twos, they are regrouped into indistinguishable clusters. Because these complex cell networks are the backbone of life - and illness - scientists have long searched for ways to splice cell clusters down to their original pairs. http://www.physorg.com/news176986612.html Biology Mon, 09 Nov 2009 10:57:46 EST news176986612 (PhysOrg.com) -- The spectacular new camera installed on NASA's Hubble Space Telescope during Servicing Mission 4 in May has delivered the most detailed view of star birth in the graceful, curving arms of the nearby spiral galaxy M83. http://www.physorg.com/news176638796.html Space & Earth Thu, 05 Nov 2009 10:20:24 EST news176638796 (PhysOrg.com) -- Astronomers have tracked down a gigantic, previously unknown assembly of galaxies located almost seven billion light-years away from us.

A new program funded by the American Recovery and Reinvestment Act through the U.S. Department of Energy will examine cloud computing as a cost-effective and energy-efficient computing paradigm for scientists to accelerate discoveries in a variety of disciplines, including analysis of scientific data sets in biology, climate change and physics. http://www.physorg.com/news174751466.html Technology Wed, 14 Oct 2009 15:05:10 EST news174751466 Researchers at Carnegie Mellon University and Intel Labs Pittsburgh (ILP) have combined low-power, embedded processors typically used in netbooks with flash memory to create a server architecture that is fast, but far more energy efficient for data-intensive applications than the systems now used by major Internet services. http://www.physorg.com/news174741979.html Electronics Wed, 14 Oct 2009 12:27:53 EST news174741979 (PhysOrg.com) -- Not surprisingly, interacting galaxies have a dramatic effect on each other. Studies have revealed that as galaxies approach one another massive amounts of gas are pulled from each galaxy towards the centre of the other, until ultimately, the two merge into one massive galaxy. The object in the image, NGC 2623, is in the late stages of the merging process with the centres of the original galaxy pair now merged into one nucleus. However, stretching out from the centre are two tidal tails of young stars showing that a merger has taken place. During such a collision, the dramatic exchange of mass and gases initiates star formation, seen here in both the tails. http://www.physorg.com/news174649432.html Space & Earth Tue, 13 Oct 2009 11:20:41 EST news174649432 Australian scientists have found that the bacterium Cupriavidus metallidurans catalyses the biomineralisation of gold by transforming toxic gold compounds to their metallic form using active cellular mechanism. http://www.physorg.com/news174140990.html Physics Wed, 07 Oct 2009 14:20:01 EST news174140990 (PhysOrg.com) -- Ram pressure is the drag force that results when something moves through a fluid -- much like the wind you feel in your face when bicycling, even on a still day -- and occurs in this context as galaxies orbiting about the centre of the cluster move through the intra-cluster medium, which then sweeps out gas from within the galaxies. http://www.physorg.com/news173529292.html Space & Earth Wed, 30 Sep 2009 11:36:07 EST news173529292 The newly released image extends across a field of view of more than one and a half square degree - an area eight times larger than that of the full Moon - and was obtained with the Wide Field Imager attached to the MPG/ESO 2.2-metre telescope at the La Silla Observatory in Chile.

The scientists have produced a ground-breaking study of what could be called "cosmic feeding". It has now been published in the prestigious scientific journal Astronomy and Astrophysics. http://www.physorg.com/news171293489.html Space & Earth Fri, 04 Sep 2009 14:33:18 EST news171293489 Small, smaller, "nano" data storage! Interest is growing in the use of metallofullerenes - carbon `cages` with embedded metallic compounds - as materials for miniature data storage devices. Researchers at Empa have discovered that metallofullerenes are capable of forming ordered supramolecular structures with different orientations. By specifically manipulating these orientations it might be possible to store and subsequently read out information. http://www.physorg.com/news171041009.html Nanotechnology Tue, 01 Sep 2009 16:24:05 EST news171041009 (PhysOrg.com) -- Researchers at the University of Warwick have found what could be the signal of ideal wave "surfing" conditions for individual particles within the massive turbulent ocean of the solar wind. The discovery could give a new insight into just how energy is dissipated in solar system sized plasmas such as the solar wind and could provide significant clues to scientists developing fusion power which relies on plasmas. http://www.physorg.com/news170947797.html Physics Mon, 31 Aug 2009 14:30:59 EST news170947797 (PhysOrg.com) -- Computer scientists have developed an inexpensive solution for diagnosing networking delays in data center networks as short as tens of millionths of seconds -delays that can lead to multi-million dollar losses for investment banks running automatic stock trading systems. Similar delays can delay parallel processing in high performance cluster computing applications run by Fortune 500 companies and universities. http://www.physorg.com/news169997201.html Technology Thu, 20 Aug 2009 14:40:01 EST news169997201 The dense star cluster RCW 38 glistens about 5500 light years away in the direction of the constellation Vela (the Sails). Like the Orion Nebula Cluster, RCW 38 is an "embedded cluster", in that the nascent cloud of dust and gas still envelops its stars. Astronomers have determined that most stars, including the low mass, reddish ones that outnumber all others in the Universe, originate in these matter-rich locations. Accordingly, embedded clusters provide scientists with a living laboratory in which to explore the mechanisms of star and planetary formation. http://www.physorg.com/news169894333.html Space & Earth Wed, 19 Aug 2009 09:52:41 EST news169894333 A 17-member team has found what may be the smoking gun of a much-debated proposal that a cosmic impact about 12,900 years ago ripped through North America and drove multiple species into extinction. http://www.physorg.com/news167329938.html Space & Earth Mon, 20 Jul 2009 18:20:01 EST news167329938 (PhysOrg.com) -- Today ESO has released a new and stunning image of the sky around the Eagle Nebula, a stellar nursery where infant star clusters carve out monster columns of dust and gas. http://www.physorg.com/news166960881.html Space & Earth Thu, 16 Jul 2009 11:01:41 EST news166960881 An international team of researchers led by a UC Riverside astronomer has completed the largest ever survey designed to find very distant clusters of galaxies. http://www.physorg.com/news165601534.html Space & Earth Tue, 30 Jun 2009 17:26:07 EST news165601534 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 The joint Japan-U.S. Suzaku mission is providing new insight into how assemblages of thousands of galaxies pull themselves together.
