Like other users of microfluidic systems, National Institute of Standards and Technology researcher Javier Atencia was faced with an annoying engineering problem: how to simply, reliably and most of all, tightly, connect his tiny devices to the external pumps and reservoirs delivering liquids into the system. While pondering this one day, he randomly picked up two magnets and began playing with them. As the magnets pulled apart and then snapped back together, Atencia realized that he had his solution. http://www.physorg.com/news177761689.html Physics Wed, 18 Nov 2009 11:00:02 EST news177761689 (PhysOrg.com) -- All seven contracts for the production of the NSLS-II storage ring magnets have now been awarded -- a significant milestone for the project. The magnets -- 750 in total -- will be made by vendors in the United States, Russia, China, Europe, and New Zealand. http://www.physorg.com/news177020042.html Physics Mon, 09 Nov 2009 20:30:01 EST news177020042 The diversity of colours, shapes, and sizes of planetary nebulae make them fascinating objects. In this photo release Calar Alto presents a rather unique view combining both optical and near-infrared data of the Ring Nebula (M57). http://www.physorg.com/news176374973.html Space & Earth Mon, 02 Nov 2009 09:20:01 EST news176374973 The National Institutes of Health has awarded Albert Einstein College of Medicine of Yeshiva University a four-year, $7.2 million grant to develop a microbicide-releasing vaginal ring to prevent HIV transmission. http://www.physorg.com/news173724660.html Medicine & Health Fri, 02 Oct 2009 18:20:01 EST news173724660 (PhysOrg.com) -- Soman, Tabun, and Sarin (which has already been used in terrorist attacks) are chemical weapons that attack the nervous system. When inhaled, these extremely toxic organophosphates can lead to death within minutes. The search for fast, simple detection methods for these colorless and odorless gases, which are unfortunately relatively easily manufactured, is correspondingly urgent. http://www.physorg.com/news172316206.html Chemistry Wed, 16 Sep 2009 10:37:54 EST news172316206 Scientists are comparing annual growth rings of the Pacific Northwest's largest bivalve and its most iconic tree for clues to how living organisms may have responded to changes in climate. http://www.physorg.com/news168174866.html Space & Earth Thu, 30 Jul 2009 12:16:15 EST news168174866 In a research article published in this week's PLoS Medicine, Ann Killary (from the University of Texas M. D. Anderson Cancer Center) and colleagues describe a new gene called DEAR1 that is genetically altered by mutation and deletion in breast tumors, and that may provide a new breast cancer prognostic marker. http://www.physorg.com/news160724140.html Medicine & Health Tue, 05 May 2009 06:36:04 EST news160724140 The club moss Lycopodium serratum is a creeping, flowerless plant used in homeopathic medicine to treat a wide variety of ailments. It contains a potent brew of alkaloids that have attracted considerable scientific and medical interest. However, the plant makes many of these compounds in extremely low amounts, hindering efforts to test their therapeutic value. http://www.physorg.com/news159037185.html Chemistry Wed, 15 Apr 2009 18:01:03 EST news159037185 On 24 February 2009, the NASA/ESA Hubble Space Telescope captured a photo sequence of four moons of Saturn passing in front of their parent planet. The moons, from far left to right, are the white icy moons Enceladus and Dione, the large orange moon Titan, and icy Mimas. Due to the angle of the Sun, they are each preceded by their own shadow. http://www.physorg.com/news156514110.html Space & Earth Tue, 17 Mar 2009 13:09:01 EST news156514110 (PhysOrg.com) -- NASA's Cassini spacecraft has found within Saturn's G ring an embedded moonlet that appears as a faint, moving pinprick of light. Scientists believe it is a main source of the G ring and its single ring arc. http://www.physorg.com/news155318928.html Space & Earth Tue, 03 Mar 2009 16:09:19 EST news155318928 (PhysOrg.com) -- In 2006, astronomer Alice Quillen of the University of Rochester predicted that a planet of a particular size and orbit must lie within the dust of a nearby star. That planet has now been photographed by the Hubble Space Telescope, making it only the second planet ever imaged after an accurate prediction. The only other planet seen after an accurate prediction was Neptune, discovered more than 160 years ago. http://www.physorg.com/news148055747.html Space & Earth Tue, 09 Dec 2008 14:35:47 EST news148055747 Researchers from the Ludwig Institute for Cancer Research at the University of California, San Diego School of Medicine have identified a key step required for cell division in a study that could help improve therapies to treat cancer. Their work describing the mechanism of the contractile ring - a structure that pinches the mother cell into two daughter cells - has been published in the December 5 issue of the journal Science. http://www.physorg.com/news148049853.html Biology Tue, 09 Dec 2008 12:57:33 EST news148049853 (PhysOrg.com) -- Estimated to be no more than three times Jupiter's mass, the planet, called Fomalhaut b, orbits the bright southern star Fomalhaut, located 25 light-years away in the constellation Piscis Austrinus (the Southern Fish). http://www.physorg.com/news145806946.html Space & Earth Thu, 13 Nov 2008 13:55:46 EST news145806946 (PhysOrg.com) -- NASA's Galaxy Evolution Explorer has lifted the veil off a ghost known to haunt the local universe, providing new insight into the formation and evolution of galaxies. http://www.physorg.com/news144679480.html Space & Earth Fri, 31 Oct 2008 13:44:40 EST news144679480 (PhysOrg.com) -- The Hubble Space Telescope is back in business after a one-month breakdown with a snapshot of the fascinating galaxy pair Arp 147. Scientists made two repair attempts, and last week's effort apparently worked. http://www.physorg.com/news144581056.html Space & Earth Thu, 30 Oct 2008 10:24:16 EST news144581056 (PhysOrg.com) -- NASA's Cassini spacecraft has detected a faint, partial ring orbiting with one small moon of Saturn, and has confirmed the presence of another partial ring orbiting with a second moon. This is further evidence that most of the planet's small, inner moons orbit within partial or complete rings. http://www.physorg.com/news139841673.html Space & Earth Fri, 05 Sep 2008 13:54:33 EST news139841673 A new study at Oregon State University has finally resolved a controversy that cellular biologists have been arguing over for nearly 50 years, with findings that may aid research on everything from birth defects and genetic diseases to the most classic "cell division" issue of them all - cancer. http://www.physorg.com/news139635986.html Biology Wed, 03 Sep 2008 04:46:26 EST news139635986 When a cell begins to multiply in a dangerously abnormal way, a series of death signals trigger it to self-destruct before it turns cancerous. Now, in research to appear in the August 15 issue of Genes & Development, Rockefeller University scientists have figured out a way in mice to amplify the signals that tell these precancerous cells to die. The trick: Inactivating a protein that normally helps cells to avoid self-destruction. http://www.physorg.com/news138027888.html Medicine & Health Fri, 15 Aug 2008 14:04:48 EST news138027888 New research has uncovered how different crimson rosella populations are related to each other - a discovery which has important implications for research into how climate change may affect Australia`s biodiversity. http://www.physorg.com/news136643514.html Biology Wed, 30 Jul 2008 13:31:54 EST news136643514 Again and again, experiments confirmed it. Without glia, neurons die. So scientists who wanted to study in living animals what glia - the most abundant brain cells - do for neurons besides keep them alive were out of luck. But now, a breakthrough. http://www.physorg.com/news135263394.html Biology Mon, 14 Jul 2008 14:09:54 EST news135263394 A puzzle in the control of cell division, one of the most fundamental processes in all biology, has been unravelled by Oxford University researchers. http://www.physorg.com/news134311778.html Biology Thu, 03 Jul 2008 13:49:38 EST news134311778
