Older adults with long-term exposure to higher levels of pollution are at higher risk for hospitalization for pneumonia, according to researchers in Canada. http://www.physorg.com/news180768309.html Medicine & Health Wed, 23 Dec 2009 06:40:02 EST news180768309 (AP) -- Philippine troops on Monday pressed the last 3,000 villagers who have refused to heed government warnings to leave the danger zone around a volcano that experts say is ready to erupt. http://www.physorg.com/news180594352.html Space & Earth Mon, 21 Dec 2009 05:06:42 EST news180594352 Bacteria possess an ingenious mechanism for preventing oxygen from harming the building blocks of the cell. This is the new finding of a team of biologists that includes Joris Messens of VIB, a life sciences research institute in Flanders, Belgium, connected to the Vrije Universiteit Brussel. The scientists made this discovery by modifying the DNA of the intestinal bacterium Escherichia coli. http://www.physorg.com/news177944623.html Biology Fri, 20 Nov 2009 13:30:01 EST news177944623 (PhysOrg.com) -- Much of our planet's mineral wealth was deposited billions of years ago when Earth's chemical cycles were different from today's. Using geochemical clues from rocks nearly 3 billion years old, a group of scientists including Andrey Bekker and Doug Rumble from the Carnegie Institution have made the surprising discovery that the creation of economically important nickel ore deposits was linked to sulfur in the ancient oxygen-poor atmosphere. http://www.physorg.com/news177863954.html Space & Earth Thu, 19 Nov 2009 15:30:01 EST news177863954 (PhysOrg.com) -- A team of chemists from the U.S. and France has found compelling evidence of a previously undocumented large volcanic eruption that occurred exactly 200 years ago, in 1809. http://www.physorg.com/news176049231.html Space & Earth Thu, 29 Oct 2009 15:35:09 EST news176049231 A new report from the National Research Council examines and, when possible, estimates "hidden" costs of energy production and use -- such as the damage air pollution imposes on human health -- that are not reflected in market prices of coal, oil, other energy sources, or the electricity and gasoline produced from them. The report estimates dollar values for several major components of these costs. The damages the committee was able to quantify were an estimated $120 billion in the U.S. in 2005, a number that reflects primarily health damages from air pollution associated with electricity generation and motor vehicle transportation. The figure does not include damages from climate change, harm to ecosystems, effects of some air pollutants such as mercury, and risks to national security, which the report examines but does not monetize. http://www.physorg.com/news175174465.html Space & Earth Mon, 19 Oct 2009 12:50:02 EST news175174465 Scientists are reporting the first evidence that China's sharp focus on reducing widespread damage to soil by acid rain by restricting sulfur dioxide air pollution may have an unexpected consequence: Gains from that pollution control program will be largely offset by increases in nitrogen emissions, which the country's current policy largely overlooks. The study, which suggests that government officials adapt a more comprehensive pollution control strategy that includes a new emphasis on cutting nitrogen emissions, is scheduled for the Nov. 1 issue of ACS' Environmental Science & Technology. http://www.physorg.com/news174746733.html Space & Earth Wed, 14 Oct 2009 15:10:01 EST news174746733 (PhysOrg.com) -- A knowledge gap exists in the area of climate research: for decades, scientists have been asking themselves whether, and to what extent man-made aerosols, that is, dust particles suspended in the atmosphere, enlarge the cloud cover and thus curb climate warming. http://www.physorg.com/news174049928.html Space & Earth Tue, 06 Oct 2009 12:30:06 EST news174049928 A high-speed chase across the Panama Canal in a Boston Whaler may sound like the beginning of another James Bond film -but the protagonist of this story brandishes a butterfly net and studies the effects of climate change on insect migrations at the Smithsonian Tropical Research Institute. http://www.physorg.com/news173969205.html Biology Mon, 05 Oct 2009 13:48:00 EST news173969205 Tiny objects known as nanoparticles are often heralded as holding great potential for future applications in electronics, medicine and other areas. The properties of nanoparticles depend on their size and structure. Now researchers from North Carolina State University have learned how to consistently create hollow, solid and amorphous nanoparticles of nickel phosphide, which has potential uses in the development of solar cells and as catalysts for removing sulfur from fuel. Their work can now serve as a "how-to" guide for other researchers to controllably create hollow, solid and amorphous nanoparticles - in order to determine what special properties they may have. http://www.physorg.com/news173008630.html Nanotechnology Thu, 24 Sep 2009 11:30:02 EST news173008630 The Department of Energy's Pacific Northwest National Laboratory has developed a reusable organic liquid that can pull harmful gases such as carbon dioxide or sulfur dioxide out of industrial emissions from power plants. The process could directly replace current methods and allow power plants to capture double the amount of harmful gases in a way that uses no water, less energy and saves money. http://www.physorg.com/news169810723.html Chemistry Tue, 18 Aug 2009 10:39:30 EST news169810723 Imagine Earth without an atmosphere - without clouds, wind or air. Earth's atmosphere protects, transports, and reacts to life on Earth. http://www.physorg.com/news168707591.html Space & Earth Wed, 05 Aug 2009 16:40:02 EST news168707591 Iron and manganese compounds, in addition to sulfate, may play an important role in converting methane to carbon dioxide and eventually carbonates in the Earth's oceans, according to a team of researchers looking at anaerobic sediments. These same compounds may have been key to methane reduction in the early, oxygenless days of the planet's atmosphere. http://www.physorg.com/news166367681.html Space & Earth Thu, 09 Jul 2009 14:15:22 EST news166367681 Rising levels of smokestack emissions from oceangoing ships will cause an estimated 87,000 deaths worldwide each year by 2012 -- almost one-third higher than previously believed, according to the second major study on that topic. The study says that government action to reduce sulfur emissions from shipping fuel (the source of air pollution linked to an increased risk of illness and death) could reduce that toll. The study is in the current issue of ACS' Environmental Science & Technology. http://www.physorg.com/news166268131.html Space & Earth Wed, 08 Jul 2009 10:35:54 EST news166268131 Scientists have unearthed striking evidence for a sudden ancient collapse in plant biodiversity. A trove of 200 million-year-old fossil leaves collected in East Greenland tells the story, carrying its message across time to us today. http://www.physorg.com/news164556026.html Space & Earth Thu, 18 Jun 2009 15:50:01 EST news164556026 Those worried about a performance drop-off going from standard diesel fuel to the more environmentally friendly B20 biodiesel blend can ease their minds. http://www.physorg.com/news163780702.html Technology Tue, 09 Jun 2009 15:38:49 EST news163780702 (AP) -- The summit of Hawaii's Kilauea volcano is glowing brightly as molten lava swirls 300 feet below its crater's floor, bubbling near the surface after years of spewing from the volcano's side. http://www.physorg.com/news163560445.html Space & Earth Sun, 07 Jun 2009 02:28:27 EST news163560445 A new sponge-like material that is black, brittle and freeze-dried (just like the ice cream astronauts eat) can pull off some pretty impressive feats. Designed by Northwestern University chemists, it can remove mercury from polluted water, easily separate hydrogen from other gases and, perhaps most impressive of all, is a more effective catalyst than the one currently used to pull sulfur out of crude oil. http://www.physorg.com/news161787550.html Chemistry Sun, 17 May 2009 13:59:46 EST news161787550 (PhysOrg.com) -- Geologists may have uncovered the answer to an age-old question - an ice-age-old question, that is. It appears that Earth's earliest ice ages may have been due to the rise of oxygen in Earth's atmosphere, which consumed atmospheric greenhouse gases and chilled the earth. http://www.physorg.com/news160910438.html Space & Earth Thu, 07 May 2009 10:21:43 EST news160910438 The Environmental Protection Agency on Tuesday called for the nation's first limits on mercury emissions from the more than 100 cement factories across the U.S. http://www.physorg.com/news159646809.html Space & Earth Wed, 22 Apr 2009 19:21:01 EST news159646809 (PhysOrg.com) -- A reservoir of briny liquid buried deep beneath an Antarctic glacier supports hardy microbes that have lived in isolation for millions of years, researchers report this week in the journal Science. http://www.physorg.com/news159111927.html Space & Earth Thu, 16 Apr 2009 14:46:18 EST news159111927 (PhysOrg.com) -- Sedimentary rocks created more than 2.4 billion years ago sometimes have an unusual sulfur isotope composition thought to be caused by the action of ultra violet light on volcanically produced sulfur dioxide in an oxygen poor atmosphere. Now a team of geochemists can show an alternative origin for this isotopic composition that may point to an early, oxygen-rich atmosphere. http://www.physorg.com/news159111288.html Space & Earth Thu, 16 Apr 2009 14:35:26 EST news159111288 Researchers at Temple University Maurice H. Kornberg School of Dentistry found that a color-changing oral strip is as effective in detecting periodontal disease as traditional methods, and is easier and less costly to administer. http://www.physorg.com/news158584347.html Medicine & Health Fri, 10 Apr 2009 12:12:56 EST news158584347 The Kilauea Volcano located on the Big Island of Hawaii is currently registering an Orange Alert which means the volcano is exhibiting a heightened or elevated risk of eruption or is erupting with minor or no volcanic ash emissions.
