    Kangaroos have ‘green’ farts

    The farts and belches of these animals contain less methane than do those from other big grass grazers. Microbes in their digestive tract appear to explain the ‘roos lower production of this greenhouse gas, a new study finds.

    Return of the giant zombie virus

    Scientists have discovered a new type of virus in Siberian soils. It's the largest virus ever discovered. And guess what: It could infect cells even after 30,000 years in cold storage.

    Some of chocolate’s health benefits may trace to ‘bugs’

    Dark chocolate offers people a number of health benefits. A new study finds that the breakdown of chocolate by microbes in the human gut be behind some benefits.

    Intel STS finalist finds new flu fighters

    Intel Science Talent Search finalist Eric Chen used a computer simulation to narrow down chemical targets to fight influenza. The drugs that he identified could be the next big weapons against flu.

  5. Animals

    Passing diseases from bee to bee

    A study finds that the viruses and parasites that plague honeybees can infect bumblebees too, sickening another important pollinator.

  6. Animals

    ‘Crazy’ ant fight

    By neutralizing the poison produced by fire ants, ‘crazy’ ants can survive heated battles. And that may help explain why crazy ants are edging out fire ants in parts of the southern United States.

    First living fish leaves ‘endangered’ list

    Twenty-one years ago, a minnow facing a high risk of extinction was placed on the U.S. Endangered Species List. With help from scientists, the fish appears to have largely recovered. It’s the first ‘listed’ fish to do so.
