  • Tundra Carbon Impact?

    There is a concern with the carbon stored in the form of frozen partially decomposed vegetation in the vast tundra of the north. When the permafrost melts, it may releases carbon in the form of carbon dioxide and methane, both of which are greenhouse gases. The amount of greenhouse gases which will be released from…

  • April Showers

    They say “April showers bring May flowers” and this year, April really did live up to its expectations of bringing down the rain. According to the National Oceanic and Atmospheric Administration (NOAA), the average precipitation for April in the contiguous US was 2.9 inches! This is 0.27 inches above average tying April 1953 as the…

  • EarthTalk: Climate Change and Hawaii’s Coral Reefs

    Despite sweeping protections put in place near the end of George W. Bush’s presidency for large swaths of marine ecosystems around the Hawaiian Islands, things are not looking good for Hawaii’s coral reefs. Poisonous run-off, rising ocean levels, increasingly acidic waters and overfishing are taking their toll on the reefs and the marine life they…

  • Ancient Trapped Water

    The world is a big place with a lot of cavities and hidden places. Scientists have now discovered water that has been trapped in rock for more than a billion years. The water might contain microbes that evolved independently from the surface world, and it’s a finding that gives new hope to the search for…

  • Mount Everest glaciers have shrunk 13% in 50 years

    Glaciers in the Mount Everest region have shrunk by 13 percent and the snow-line has shifted 180 meters (590 feet) higher during the past 50 years, according to a study that will be presented this week at a conference organized by the American Geophysical Union.

  • Eating More Protein is Associated with Weight Loss

    At some point in our lives, we have been on some kind of diet or other. There is the ‘cabbage soup diet’; ‘5:2 diet’; and then high protein diets such as Atkins, Zone and South Beach, etc. Some people turn to higher-protein diets to lose weight, because some studies suggest that higher-protein diets help people…

  • Nature is Good for your Health!

    A walk in the park can calm and restore you. This is something we take for granted in parks and recreation, because we have known it to be true ever since we started spending time in nature. But new research reported in the British Journal of Sports Medicine now provides scientific proof that walking in…

  • What is Really Pristine Wilderness Really?

    New research shows that humans have been transforming the earth and its ecosystems for millenniums — far longer than previously believed. These findings call into question our notions about what is unspoiled nature and what should be preserved. Are there any pristine ecosystems out there? The evidence is growing that our ideas about virgin nature…

  • Makran Earthquakes

    Earthquakes happen but where they may happen as well as when is a matter to be studied. Earthquakes similar in magnitude to the 2004 Sumatra earthquake could occur in an area beneath the Arabian Sea at the Makran subduction zone which is just south of Pakistan, according to recent research published in Geophysical Research Letters.…

  • Web tool tracks insecticide-resistant malaria mosquitoes

    An online mapping system to track insecticide resistance in malaria-causing mosquitoes around the world has been launched. The free interactive website identifies places in more than 50 malaria-endemic countries where mosquitoes have become resistant to the insecticides used in bed nets and indoor sprays. IR Mapper was launched last month (25 April) by Vestergaard Frandsen,…
