    Science 8 July 2011: Vol. 333 no. 6039 pp. 173-175 Galaxy Zoo Volunteers Share Pain and Glory of Research 1. Daniel Clery A project to "crowdsource" galactic classifications has paid off in ways the astronomers who started it never expected. Figure View larger version: * In this page * In a new window Space oddity. Greenish "voorwerp" spotted by a Dutch volunteer still intrigues scientists. "CREDIT: NASA, ESA, W. KEEL (UNIVERSITY OF ALABAMA), AND THE GALAXY ZOO TEAM" The automated surveys that are becoming increasingly common in astronomy are producing an embarrassment of riches for researchers. Projects such as the Sloan Digital Sky Survey (SDSS) are generating so much data that, in some cases, astronomers don't know what to do with them all. SDSS has compiled a list of more than 1 million galaxies. To glean information about galaxy evolution, however, astronomers need to know what type of galaxy each one is: spiral, barred spiral, elliptical, or something else. At present, the only reliable way to classify galaxies is to look at each one. But the SDSS list is so long that all the world's astronomers working together couldn't muster enough eyeballs for the task. Enter the "wisdom of crowds." An online effort called Galaxy Zoo, launched in 2007, set a standard for citizen-scientist participation projects. Zealous volunteers astonished the project's organizers by classifying the entire catalog years ahead of schedule. The results have brought real statistical rigor to a field used to samples too small to support firm conclusions. But that's not all. Buoyed by the curiosity and dedication of the volunteers, the Galaxy Zoo team went on to ask more-complicated classification questions that led to studies they hadn't thought possible. And in an online discussion forum on the Galaxy Zoo Web site, volunteers have pointed to anomalies that on closer inspection have turned out to be genuinely new astronomical objects.

    Webcast: 'We Sea Change,' a Climate Change Education Video 0 What is climate change, and how is it affecting coastal Carolina? That is the question that a group of teens from Isaac Bear Early College High School set out to answer for their Third National Student Summit on the Ocean & Coasts project. Representing the North Carolina Aquarium at Fort Fisher, four teens spent months researching climate change issues such as salt water intrusion in rivers, changes to barrier islands, disappearing beaches, and habitat loss in longleaf pine forests in the Wilmington, N.C., region. The students presented a video documenting this research during the National Student Summit on February 15, 2011 at the Smithsonian's National Museum of Natural History. After the Summit, the team broadened the project's scope to include climate change education through the production of a second video. This film, We Sea Change, aims to give their local community in Wilmington an understanding of climate change, impacts on the coastal Carolina region, and how people can be part of the climate change solution. We Sea Change will be broadcast live to the Ocean Portal from the North Carolina Aquarium at Fort Fisher on Wednesday, September 28, 2011 at 7pm. There will be a panel discussion on climate change immediately following the 7pm screening. Meet the team! The Cape Fear Beach Bears: Sandy Paws for a Cause team members include students Jessica Lama, Keela Sweeney, Evan Lucas, and Dustin Chambers. They have conducted research and produced their videos under the guidance of teachers Bryan Bishop from Isaac Bear Early College High School and Megan Ennes from the North Carolina Aquarium at Fort Fisher.

"orange goo" found in Alaska - 0 views

    http://www.alaskafisheries.noaa.gov/newsreleases/2011/orangesubstance081811.pdf Alaska - NOAA determines "orange goo" in Alaska's Kivalina village is fungal spores The "orange goo" that washed ashore earlier this month in the remote Eskimo village of Kivalina along Alaska's northwest coast is fungal spores, not microscopic eggs as preliminary analysis indicated. Scientists at the NOAA Alaska Fisheries Science Center's Auke Bay Laboratory announced last week that the substance was biological in nature, rather than oil or pollution as originally thought by concerned residents of Kivalina. Per standard scientific procedure, samples were sent to NOAA's Analytical Response Team for a more thorough and detailed analysis and verification process. At NOAA's National Ocean Service Center for Coastal Environmental Health and Biomolecular Research, based in Charleston, S.C., a team of scientists highly-specialized and equipped to analyze microbiologic phenomena such as this determined that the substance is consistent with spores from a fungi that cause rust, a disease that infects only plants causing a rust-like appearance on leaves and stems. Rust fungi reproduce to infect other plants by releasing spores which disperse often times great distances by wind and water. However, whether this spore belongs to one of the 7,800 known species of rust fungi has not yet been determined. More information will be posted on the Alaska Fisheries Science Center website as it becomes available.

NOAA awards grant to advance harmful algal bloom warnings to protect public and animal ... - 0 views

  •  
    Scientists researching harmful algal bloom "hot spots" off southern and central California have been awarded $821,673 for the first year of an anticipated 5-year $4,076,929 project to investigate methods that could provide early warning detection of the toxic blooms, also known as red tides. The research is being conducted in partnership with two U.S. Integrated Ocean Observing System partners - the Central and Northern California Ocean Observing System and the Southern California Coastal Ocean Observing System. The teams will combine the detection and monitoring of the toxic blooms with ocean models that can forecast ocean conditions, potentially leading to bloom predictions.

Humans Are Driving Extreme Weather; Time to Prepare - 0 views

    "Science 25 November 2011: Vol. 334 no. 6059 p. 1040 DOI: 10.1126/science.334.6059.1040 * News & Analysis Climate Change Humans Are Driving Extreme Weather; Time to Prepare 1. Richard A. Kerr Figure View larger version: * In this page * In a new window Thai floods 2011 Hurricane Katrina 2005 Texas drought 2011 "CREDITS (LEFT TO RIGHT): PAULA BRONSTEIN/GETTY IMAGES; JEFF SCHMALTZ, MODIS RAPID RESPONSE TEAM, NASA/GSFC; NOAA" An international scientific assessment finds for the first time that human activity has indeed driven not just global warming but also increases in some extreme weather and climate events around the world in recent decades. And those and likely other weather extremes will worsen in coming decades as greenhouse gases mount, the report finds. But uncertainties are rife in the still-emerging field of extreme events. Scientists cannot attribute a particular drought or flood to global warming, and they can say little about past or future trends in the risk of high-profile hazards such as tropical cyclones. Damage from weather disasters has been climbing, but the report can attribute that trend only to the increasing exposure of life and property to weather risks. Climate change may be involved, but a case cannot yet be made. Despite the uncertainties, the special report from the Intergovernmental Panel on Climate Change (IPCC) released 18 November stresses that there is still reason for taking action now. The panel recommends "low-regrets measures," such as improvements in everything from drainage systems to early warning systems. Such measures would benefit society in dealing with the current climate as well as with almost any range of possible future climates. The report takes a cautious, consensus-based approach that draws on the published literature. Headlines and even some scientists may point to the current Texas drought or the 2003 European heat wave as the result of the strengthening greenhouse. But the report fin

    "Stephanie Keske does computer visualization work, and is starting a graduate program this fall at Texas A&M University. She told me, "Just living on a ship, I think … you know, I try to be outside as much as I can so just being trapped on a floating hunk of metal is maybe going to be a little difficult. I don't know: I've never been in one place with an inability to leave it for 2 months solid." At the moment, Keske's in the northeast Pacific onboard an oceanographic research vessel. She and six other educators and artists from the US and France are working with the science team to do unprecedented outreach. Have a listen."

Right Whales Finally Coming Home - 0 views

    Right Whales Finally Coming Home Figure "CREDIT: MICHAËL CATANZARITI/WIKIMEDIA COMMONS" After more than 100 years, right whales have returned to their calving grounds in New Zealand, an international team of scientists reports. The 100-ton whales, known for their social frolicking and impressive acrobatic displays, were hunted to extinction in these same waters during the 19th and 20th centuries' era of industrial whaling. A small population managed to survive near remote, sub-Antarctic islands south of New Zealand. In recent years, a few dozen females found their way back to the same bays their ancestors used for bearing their young. Normally, such cultural knowledge is passed from mother to daughter, the researchers say. But the tradition had been lost, until these pioneering females began making the journey once again. Reporting in Marine Ecology Progress Series, the scientists-from Canada, the United States, Australia, and New Zealand-confirmed that some of the females had migrated from the southern islands to New Zealand by comparing the DNA in tissue samples collected from seven whales at both sites. Now that the tradition has been restored, scientists expect more whales to follow the pioneers.
