    Great river cycles carbon quickly

    Some of the organic material carried to the sea by the Amazon is thousands of years old, but much of the carbon in carbon dioxide emanating from the river was stored in plants for less than a decade.

    Lyme microbe forms convenient bond with tick protein

    The bacterium that causes Lyme disease commandeers a gene in the deer tick, inducing overproduction of a salivary protein that the bacterium uses to escape immune detection once it's inside a mammal.

    Life thrived below solid ice shelf

    A survey of a segment of Antarctic seafloor that until recently had laid beneath a thick, floating ice shelf for thousands of years has revealed an ecosystem apparently based on chemical nourishment, not sunshine.

    Speed Reader: Gene sequencing gets a boost

    The first lab-ready technology to challenge the dominant gene-sequencing technique known as the Sanger method taps miniaturization and parallel reading of hundreds of thousands of DNA stretches to boost speed and slash cost.
