  • Can ecotourism save threatened species?

    Ecotourism can provide the critical difference between survival and extinction for endangered animals, according to new research from Griffith University.Using population viability modelling, the Griffith team of Professor Ralf Buckley, Dr Guy Castley and Dr Clare Morrison has developed a method that for the first time quantifies the impact of ecotourism on threatened species.

  • Giant Iceberg Causes Penguin Deaths

    For the past six years, an iceberg the size of Rome has blocked the access of Adélie penguins to the sea in Antarctica. To find food, they must walk a detour of nearly 40 miles to the coast.The impact on the colony has been devastating: More than 150,000 penguins have died.The approximately 1,800-square-mile iceberg (referred…

  • Algal Toxins Detected in One-Third of Streams Assessed in Southeastern United States

    USGS scientists have detected toxins known as microcystins produced by various forms of algae in 39 percent of the small streams assessed throughout the southeastern United States. Their recent study looked at 75 streams in portions of Alabama, Georgia, North Carolina, South Carolina and Virginia.

  • UCLA studies the long-term health impacts of ozone

     Adults with long-term exposure to ozone (O3) face an increased risk of dying from respiratory and cardiovascular diseases, a study  “Long-Term Ozone Exposure and Mortality in a Large Prospective Study” published online ahead of print in the American Thoracic Society’s American Journal of Respiratory and Critical Care Medicine suggests.Using data from a large U.S. study begun in 1982,…

  • Lawrence Livermore Laboratory looking at ways to deflect killer asteroids

    Asteroids headed for a collision with the Earth, if found early enough, can be acted upon to prevent the potentially devastating consequences of an impact. One technique to divert an asteroid, called kinetic impact, uses a spacecraft to crash into the body at high speeds.This approach delivers the momentum of the spacecraft, while also providing…

  • Smart water management could help produce much more food

    Improved agricultural water management could halve the global food gap by 2050 and buffer some of the harmful climate change effects on crop yields. For the first time, scientists investigated systematically the worldwide potential to produce more food with the same amount of water by optimizing rain use and irrigation. They found the potential has…

  • The differences between organic and non-organic milk and meat

    A new study has shown that both organic milk and meat contain around 50% more beneficial omega-3 fatty acids than conventionally produced products. Analysing data from around the world, the team led by Newcastle University, reviewed 196 papers on milk and 67 papers on meat and found clear differences between organic and conventional milk and meat, especially…

  • What is your dog's IQ?

    Researchers in Scotland are attempting to come up with an easy, fast and reliable canine IQ test. This comes after an initial study showed that much like in humans, intelligence in dogs varies considerably. Similarly to human IQ tests, the canine IQ test used spatial patterns and problem solving to determine an underlying intelligence. To administer the test…
