NASA satellites 'eyes' changes in Hurricane Katia
T, 09/06/2011 - 06:00(NASA/Goddard Space Flight Center) Major Hurricane Katia continues to approach the US East coast and stir up rough surf. Meanwhile two NASA satellites have provided a look at the changes in organization and cloud patterns over the last several days.
NASA spacecraft images offer sharper views of Apollo landing sites
T, 09/06/2011 - 06:00(NASA/Goddard Space Flight Center) NASA's Lunar Reconnaissance Orbiter (LRO) captured the sharpest images ever taken from space of the Apollo 12, 14 and 17 landing sites. Images show the twists and turns of the paths made when the astronauts explored the lunar surface.
Peer pressure? It's hardwired into our brains
T, 09/06/2011 - 06:00(University of Southern California) A new USC study explains why people take stupid chances when all of their friends are watching that they would never take by themselves. According to the study, the human brain places more value on winning in a social setting than it does on winning when you're alone.
USGS research frontiers on fish at the American Fisheries Society Conference
T, 09/06/2011 - 06:00(United States Geological Survey) The 141st annual meeting of the American Fisheries Society will take place in Seattle from Sept. 4-8, 2011. The theme of this year's conference is "New Frontiers in Fisheries Management and Ecology: Leading the Way in a Changing World." For more information, visit http://afs2011.org/ All talks will be at the Washington State Convention Center.
Neutron analysis reveals unique atom-scale behavior of 'cobalt blue'
T, 09/06/2011 - 06:00(DOE/Oak Ridge National Laboratory) Neutron scattering studies of "cobalt blue," a compound prized by artists for its lustrous blue hue, are revealing unique magnetic characteristics that could answer questions about mysterious properties in other materials.
Poor outlook for water quality in Germany
T, 09/06/2011 - 06:00(Helmholtz Association of German Research Centres) The good chemical and ecological status of water bodies as defined by the EU Water Framework Directive is unlikely to be attained in Germany by 2015. This is the conclusion of a study in which data from the four largest rivers in northern Germany - the Elbe, Weser, Aller and Ems - were analysed over ten years. The study was carried out by the University of Koblenz-Landau, the UFZ and Freiberg University of Mining and Technology, and published in the international scientific journal Environmental Science & Technology.
Circadian clocks in a blind fish
T, 09/06/2011 - 06:00(Public Library of Science) Do animals that have evolved underground, completely isolated from the day-night cycle, still "know" what time it is? Does a normal circadian clock persist during evolution under constant darkness? A new study tackles these questions by investigating a species of cavefish which has lived for 2 million years beneath the Somalian desert, finding that it has an unusual circadian clock; it ticks with a period of up to 47 hours, and is completely blind.

Male-female ring finger proportions tied to sex hormones in embryo; may offer health insights
E, 09/05/2011 - 06:00(University of Florida) Providing a genetic explanation for a raft of studies that link finger proportions with traits ranging from sperm counts and musical ability to health problems such as autism, depression and heart attack, researchers have found that male and female digit proportions are determined by the balance of sex hormones during early embryonic development.
Ancient humans were mixing it up
E, 09/05/2011 - 06:00(University of Arizona) Anatomically modern humans interbred with more archaic hominin forms even before they migrated out of Africa, a UA-led team of researchers has found. The discovery suggests genetic exchange with their more morphologically diverged neighbors was more widespread than previously thought and all humans today may carry genes from now-extinct Homo species.
WHOI-led study sharpens picture of how much oil and gas flowed in Deepwater Horizon spill
E, 09/05/2011 - 06:00(Woods Hole Oceanographic Institution) In a detailed assessment of the Deepwater Horizon oil spill, researchers led by a team from the Woods Hole Oceanographic Institution (WHOI) have determined that the blown-out Macondo well spewed oil at a rate of about 57,000 barrels a day, totaling nearly 5 million barrels of oil released from the well between Apr. 20 and July 15, 2010, when the leak was capped. In addition, the well released some 100 million standard cubic feet per day of natural gas.
Yale researchers solve mystery of disappearing bird digit
P, 09/04/2011 - 06:00(Yale University) Yale researchers solve evolutionary mystery of origin of bird digits.
Fast, cheap, and accurate: Detecting CO2 with a fluorescent twist
P, 09/04/2011 - 06:00(Institute for Integrated Cell-Material Sciences, Kyoto University) Detecting specific gases in the air is possible using a number of different existing technologies, but typically all of these suffer from one or more drawbacks including high energy cost, large size, slow detection speed, and sensitivity to humidity.Overcoming these deficiencies with a unique approach, a team based at Kyoto University has designed an inexpensive new material capable of quick and accurate detection of a specific gas under a wide variety of circumstances.

N, 09/01/2011 - 06:00(NASA/Goddard Space Flight Center) An infrared satellite look at Tropical Depression 8E along the Mexican coast shows that the storm became more disorganized in the last 24 hours, and is now a remnant low pressure area.
NASA sees Katia become second Atlantic Hurricane
N, 09/01/2011 - 06:00(NASA/Goddard Space Flight Center) The second Atlantic Ocean Hurricane was born today, Sept. 1 as Katia strengthened from a tropical storm in the central Atlantic. NASA's TRMM satellite noticed towering thunderstorms within Katia yesterday which clued forecasters that she would become a hurricane today. NASA's Aqua satellite showed strong thunderstorms around Katia's center today as the hurricane continues to strengthen.
