(PhysOrg.com) -- Scientists at Cornell University in the U.S. have found a new way of breaking two of the strongest chemical bonds, at ambient temperature and pressure, and this breakthrough could lead to low-energy processes for making organic compounds containing nitrogen. http://www.physorg.com/news180170164.html Chemistry Wed, 16 Dec 2009 07:22:43 EST news180170164 (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 (PhysOrg.com) -- A new generation of optical sensors is enabling the development of robust, long-lasting, lighting-fast trace gas detectors for use in a wide range of industrial, security and domestic applications. http://www.physorg.com/news179142263.html Technology Fri, 04 Dec 2009 10:00:01 EST news179142263 Smoking tobacco through a waterpipe exposes the user to the same toxicants - carbon monoxide and nicotine - as puffing on a cigarette, which could lead to nicotine addiction and heart disease, according to a study led by a Virginia Commonwealth University researcher published in the December issue of the American Journal of Preventive Medicine. http://www.physorg.com/news178995752.html Medicine & Health Wed, 02 Dec 2009 17:03:10 EST news178995752 (PhysOrg.com) -- Researchers at Sandia National Laboratories have built a machine that uses the sun's energy to convert carbon dioxide waste from power plants into transportation fuels such as gasoline, diesel, and jet fuel. The system could provide an alternative to carbon sequestration; instead of permanently storing CO2 underground, the CO2 could be recycled and put to use. http://www.physorg.com/news178203219.html Chemistry Mon, 23 Nov 2009 13:06:36 EST news178203219 Sniff, sniff, sniff -- Yum! Sniff, sniff, sniff -- Oh, yuck!!! For almost 25 years, chemists and other scientists have tried to build a machine that can do exactly that. http://www.physorg.com/news176412689.html Chemistry Mon, 02 Nov 2009 19:50:03 EST news176412689 (PhysOrg.com) -- For decades, climate scientists have worked to identify and measure key substances -- notably greenhouse gases and aerosol particles -- that affect Earth`s climate. And they`ve been aided by ever more sophisticated computer models that make estimating the relative impact of each type of pollutant more reliable. http://www.physorg.com/news176058147.html Space & Earth Thu, 29 Oct 2009 18:03:19 EST news176058147 To subdue the steaming heat of hurricanes or to thaw out during a blizzard, gasoline-powered, portable generators are a lifeline during weather emergencies when homes are cut off without electricity. But these generators emit poisonous carbon monoxide -- a single generator can produce a hundred times more of the colorless, odorless gas than a modern car's exhaust. http://www.physorg.com/news174074356.html Technology Tue, 06 Oct 2009 19:40:01 EST news174074356 Pedestrians could reduce the amount of traffic pollution they breathe in simply by crossing the street, according to the latest research from the University of Leeds. http://www.physorg.com/news173963610.html Space & Earth Mon, 05 Oct 2009 12:13:54 EST news173963610 Beginning August 26, 2009, and continuing into September 2009, a large wildfire in the Angeles National Forest north of Los Angeles known as the Station Fire burned more than 140,000 acres through September 3. http://www.physorg.com/news171293995.html Space & Earth Fri, 04 Sep 2009 14:40:16 EST news171293995 Predatory fish are well aware of the problem: In a swarm of small fish it is hard to isolate prey. A similar situation can be found in the microcosm of atoms and molecules, whose behavior is influenced by "swarms" of electrons. In order to achieve control over single electrons in a bunch, ultrashort light pulses of a few femtoseconds duration are needed. http://www.physorg.com/news171031838.html Physics Tue, 01 Sep 2009 13:51:15 EST news171031838 Exposure to carbon monoxide, even at levels well below national limits, is associated with an increased risk of hospitalization for the elderly with heart problems, according to a study published today in Circulation: Journal of the American Heart Association. http://www.physorg.com/news170956364.html Medicine & Health Mon, 31 Aug 2009 16:53:23 EST news170956364 A UCLA study has discovered that chronic exposure during pregnancy to miniscule levels of carbon monoxide damages the cells of the fetal brain, resulting in permanent impairment. The journal BMC (BioMed Central) Neuroscience published the findings June 22 in its online edition. http://www.physorg.com/news165146334.html Medicine & Health Thu, 25 Jun 2009 11:01:40 EST news165146334 Mayo Clinic researchers have shown that very low doses of inhaled carbon monoxide in diabetic mice reverses the condition known as gastroparesis or delayed stomach emptying, a common and painful complication for many diabetic patients. The findings will be presented on June 1 at Digestive Disease Week in Chicago. http://www.physorg.com/news163095925.html Medicine & Health Mon, 01 Jun 2009 17:25:53 EST news163095925 Hours after Hurricane Ike roared ashore in Texas, more than two million homes were without power, which left some scrambling to preserve food and others looking for ways to entertain children, a move that proved to be, in some instances, poisonous. Researchers at The University of Texas Health Science Center at Houston found that 75 percent of children treated for carbon monoxide poisoning caused by gasoline-powered electrical generators were playing video games. http://www.physorg.com/news162579314.html Medicine & Health Tue, 26 May 2009 17:55:59 EST news162579314 A large, well-controlled, multi-national clinical trial program has demonstrated the effectiveness and safety of what may become the first FDA-approved medicine for idiopathic pulmonary fibrosis, or IPF. http://www.physorg.com/news161787643.html Medicine & Health Sun, 17 May 2009 14:01:16 EST news161787643 (PhysOrg.com) -- "With lots of methane in the atmosphere, it becomes clear why Pluto's atmosphere is so warm," says Emmanuel Lellouch, lead author of the paper reporting the results. http://www.physorg.com/news155220047.html Space & Earth Mon, 02 Mar 2009 12:41:26 EST news155220047 (PhysOrg.com) -- In the search for answers to the planet's biggest challenges, some MIT researchers are turning to its tiniest organisms: bacteria. http://www.physorg.com/news154107803.html Chemistry Tue, 17 Feb 2009 15:43:51 EST news154107803 (PhysOrg.com) -- A new version of an environmentally friendly, energy efficient technology that could replace combustion engines in cars and batteries in mobile devices such as phones and laptops is being researched by Aberdeen experts. http://www.physorg.com/news151076750.html Technology Tue, 13 Jan 2009 13:45:50 EST news151076750 A strange mix of oxygen found in a stony meteorite that exploded over Pueblito de Allende, Mexico nearly 40 years ago has puzzled scientists ever since. Small flecks of minerals lodged in the stone and thought to date from the beginning of the solar system have a pattern of oxygen types, or isotopes, that differs from those found in all known planetary rocks, including those from Earth, its Moon and meteorites from Mars. http://www.physorg.com/news139757643.html Space & Earth Thu, 04 Sep 2008 14:34:03 EST news139757643
