• Reaching for The Stormy Cloud with Chameleon

    Some scientists dream about big data. The dream bridges two divided realms. One realm holds lofty peaks of number-crunching scientific computation. Endless waves of big data analysis line the other realm. A deep chasm separates the two. Discoveries await those who cross these estranged lands.

    Unfortunately, data cannot move seamlessly between Hadoop (HDFS) and parallel file systems (PFS). Scientists who want to take advantage of the big data analytics available on Hadoop must copy data from parallel file systems. That can slow workflows to a crawl, especially those with terabytes of data.

  • NASA Sees Tropical Cyclone Donna Shearing Apart

    NASA's Terra satellite captured an infrared image of Tropical Cyclone Donna as it was being sheared apart by winds southeast of New Caledonia.

    An infrared image taken May 10 at 11:55 UTC (7:55 a.m. EDT), from the MODIS instrument aboard NASA's Terra satellite showed cloud top temperatures of the dying storm. Strongest thunderstorms with cloud tops so high in the troposphere they were as cold as minus 70 degrees Fahrenheit (minus 56.6 degrees Celsius) were pushed to the southeast of the center from northwesterly wind shear.

  • Climate change could increase ER visits for allergy-related asthma

    More children could wind up in hospital emergency rooms suffering from allergy-induced asthma if greenhouse gas emissions continue to rise and cause longer oak pollen seasons, according to a new study.

  • Rising Temperatures Threaten Stability of Tibetan Alpine Grasslands

    A warming climate could affect the stability of alpine grasslands in Asia’s Tibetan Plateau, threatening the ability of farmers and herders to maintain the animals that are key to their existence, and potentially upsetting the ecology of an area in which important regional river systems originate, says a new study by researchers in China and the United States.

  • Global warming kills gut bacteria in lizards

    Climate change could threaten reptiles by reducing the number of bacteria living in their guts, new research suggests.

    Scientists from the University of Exeter and the University of Toulouse found that warming of 2-3°C caused a 34% loss of microorganism diversity in the guts of common lizards (also known as viviparous lizards).

  • U.S. had 2nd wettest, 11th warmest April on record

    “April showers bring May flowers,” or so the saying goes.   

    Perhaps a more appropriate description this year might be, “Heavy April showers bring record flooding.”

  • Scottish badgers highlight the complexity of species responses to environmental change

    In a new study researchers have found that although warmer weather should benefit badger populations, the predicted human population increase in the Scottish highlands is likely to disturb badgers and counteract that effect. These results emphasise the importance of interactive effects and context-dependent responses when planning conservation management under human-induced rapid environmental change.

  • NASA Spots Powerful Tropical Cyclone Donna Between Vanuatu and New Caledonia

    Tropical Cyclone Donna continues to move through the South Pacific Ocean as a major hurricane. NASA's Aqua satellite passed over the storm and captured an image of a clear eye as the storm was located between the island nations of Vanuatu and New Caledonia. The GPM satellite found that the powerful hurricane was generating very high amounts of rainfall.

  • Leaf litter has slower decomposition rate in warm temperatures than previously thought

    The time it takes for a leaf to decompose might be the key to understanding how temperature affects ecosystems, according to Kansas State University ecologists.

  • Scientists track porpoises to assess impact of offshore wind farms

    A new study by scientists at the University of Maryland Center for Environmental Science’s Chesapeake Biological Laboratory, Cornell University and Duke University is the first in a series to understand how marine mammals like porpoises, whales, and dolphins may be affected by the construction of wind farms off the coast of Maryland. The new research offers insight into previously unknown habits of harbor porpoises in the Maryland Wind Energy Area, a 125-square-mile area off the coast of Ocean City that may be the nation’s first commercial-scale offshore wind farm.
