  • Ocean microbe communities changing, but long-term environmental impact is unclear

    Updated: 2012-02-09 19:43:59
    CORVALLIS, Ore. – As oceans warm due to climate change, water layers will mix less and affect the microbes and plankton that pump carbon out of the atmosphere – but researchers say it's still unclear whether these processes will further increase global warming or decrease it. The forces at work are enormous and the stakes huge, said Oregon State University scientists in an article to be published Friday in the journal Science.read more

  • 3-D laser map shows earthquake before and after

    Updated: 2012-02-09 19:43:33
    Geologists have a new tool to study how earthquakes change the landscape down to a few inches, and it's giving them insight into how earthquake faults behave. In the Feb. 10 issue of the journal Science, a team of scientists from the U.S., Mexico and China reports the most comprehensive before-and-after picture yet of an earthquake zone, using data from the magnitude 7.2 event that struck near Mexicali, northern Mexico in April, 2010.read more

    Updated: 2012-02-09 05:30:49
    DALLAS (Feb. 9, 2012) — In a study to be presented today at the Society for Maternal-Fetal Medicine's annual meeting, The Pregnancy Meeting ™, in Dallas, Texas, researchers will report findings that suggest that induction of labor in patients who suffer a rupture of membranes between the 34th and 37th week of gestation (before the onset of labor) does not reduce the risk of infection or respiratory problems in the newborn.read more

  • Scientists make iron transparent

    Updated: 2012-02-08 18:30:57
    At the high-brilliance synchrotron light source PETRA III, a team of DESY scientists headed by Dr. Ralf Röhlsberger has succeeded in making atomic nuclei transparent with the help of X-ray light. At the same time they have also discovered a new way to realize an optically controlled light switch that can be used to manipulate light with light, an important ingredient for efficient future quantum computers. The research results are presented in the current edition of the scientific journal Nature (DOI: 10.1038/nature10741).read more

  • NIST provides octagonal window of opportunity for carbon capture

    Updated: 2012-02-08 16:01:14
    Filtering carbon dioxide, a greenhouse gas, from factory smokestacks is a necessary, but expensive part of many manufacturing processes. However, a collaborative research team from the National Institute of Standards and Technology (NIST) and the University of Delaware has gathered new insight into the performance of a material called a zeolite that may stop carbon dioxide in its tracks far more efficiently than current scrubbers do.*read more

  • More focus on men needed in HIV prevention

    Updated: 2012-02-07 22:30:34
    Edward Mills of the University of Ottawa, Canada and colleagues argue in this week's PLoS Medicine that the HIV/AIDS response in Africa needs a more balanced approach to gender, so that both men and women are involved in HIV treatment and prevention. Traditionally, targeted efforts at reducing the impact of the HIV epidemic have focused on women and children while men have received considerably less attention.read more

  • A bronze matryoshka doll: The metal in the metal in the metal

    Updated: 2012-02-07 16:30:14
    A doll in a doll, and then one more, enveloping them from the outside – this is how Thomas Faessler explains his molecule. He packs one atom in a cage within an atom framework. With their large surfaces these structures can serve as highly efficient catalysts. Just like in the Russian wooden toy, a hull of twelve copper atoms encases a single tin atom. This hull is, in turn, enveloped by 20 further tin atoms.read more

    PHILADELPHIA -- In a study of the harsh but beautiful White Sands National Monument in New Mexico, University of Pennsylvania researchers have uncovered a unifying mechanism to explain dune patterns. The new work represents a contribution to basic science, but the findings may also hold implications for identifying when dune landscapes like those in Nebraska's Sand Hills may reach a "tipping point" under climate change, going from valuable grazing land to barren desert.read more

    DURHAM, N.C. – When Hiroaki Matsunami, Ph.D., at Duke set out to study a chemical in male mouse urine called MTMT that attracts female mice, he didn't think he would stumble into a new field of study. But the research has led scientists at Duke University Medical Center and the University of Albany to the discovery that it's the copper in our bodies that makes mammals recoil from sulfur chemical smells.read more

  • UNH ocean scientists shed new light on Mariana Trench

    DURHAM, N.H. – An ocean mapping expedition has shed new light on deepest place on Earth, the 2,500-kilometer long Mariana Trench in the western Pacific Ocean near Guam. Using a multibeam echo sounder, state-of-the-art equipment for mapping the ocean floor, scientists from the University of New Hampshire Center for Coastal and Ocean Mapping/Joint Hydrographic Center found four "bridges" spanning the trench and measured its deepest point with greater precision than ever before.read more

  • Global extinction: Gradual doom as bad as abrupt

    The deadliest mass extinction of all took a long time to kill 90 percent of Earth's marine life--and it killed in stages--according to a newly published report. It shows that mass extinctions need not be sudden events. Thomas Algeo, a geologist at the University of Cincinnati, and 13 colleagues have produced a high-resolution look at the geology of a Permian-Triassic boundary section on Ellesmere Island in the Canadian Arctic.read more

  • What drives public opinion on climate change?

    Updated: 2012-02-06 16:31:20
    Public concern about climate change has varied widely over the past few decades. For example, Gallup has been polling individuals about how much they personally worry about climate change. In 2004, 26 percent of the respondents stated that they worried "a great deal." By 2007, this proportion had risen to 41 percent. But by 2010, this fraction dropped to 28 percent. Why?read more

  • Political leaders play key role in how worried Americans are by climate change

    Updated: 2012-02-06 16:30:39
    COLUMBUS, Ohio – More than extreme weather events and the work of scientists, it is national political leaders who influence how much Americans worry about the threat of climate change, new research finds. In a study of public opinion from 2002 to 2010, researchers found that public belief that climate change was a threat peaked in 2006-2007 when Democrats and Republicans in Congress showed the most agreement on the issue. But public concern has dropped since then, as partisanship over the issue increased.read more

  • The effect of occasional binge drinking on heart disease and mortality among moderate drinkers

    Updated: 2012-02-02 15:31:00
    Most studies have found that binge drinking is associated with a loss of alcohol's protective effect against ischemic heart disease (IHD) and most studies have found an increase of coronary risk among binge drinkers. This study followed 26,786 men and women who participated in the Danish National Cohort Study in 1994, 2000, and 2005 and sought to see if binge drinking increased the risk of IHD or all-cause mortality among "light-to-moderate" drinkers: (up to 21 drinks/week for men and up to 14 drinks/week for women). A "drink" was 12g.read more

  • Heat and cold damage corals in their own ways, Scripps study shows

    Updated: 2012-02-02 15:02:00
    Around the world coral reefs are facing threats brought by climate change and dramatic shifts in sea temperatures. While ocean warming has been the primary focus for scientists and ocean policy managers, cold events can also cause large-scale coral bleaching events. A new study by scientists at Scripps Institution of Oceanography at UC San Diego compared damage to corals exposed to heat as well as cold stress. The results reveal that cool temperatures can inflict more damage in the short term, but heat is more destructive in the long run.read more
