    Monitors get weird vibes from Antarctic

    In late 2000, seismometers on islands in the South Pacific picked up vibrations that were eventually traced to a large iceberg drifting in the Ross Sea north of Antarctica.

    Symbionts affect coral’s chemistry

    The presence of symbiotic organisms in the tiny animals that build coral reefs changes the rates at which the animals take in minerals from the water, a finding that may affect the results of many research projects that have used chemical analyses of coral remains to infer past sea-surface temperatures.

    The Silent Type: Pacific Northwest hit routinely by nonquakes

    Once every 14 months or so, portions of coastal British Columbia and northwestern Washington State experience a slow ground motion that, if released all at once, would generate an earthquake measuring more than 6 on the Richter scale.

    Smog’s ozone spawns funky carpet smells

    Strange, unpleasant odors may emanate from carpets for years due to reactions caused by exposure to smoggy air.

    Feminized Frogs: Herbicide disrupts sexual growth

    At concentrations currently found in water, the widely used weed killer atrazine hormonally strips male frogs of their masculinity and may be partly responsible for global amphibian declines.

    Motion of ice across Lake Vostok revealed

    New measurements of the movement of the Antarctic ice sheet across a lake that harbors microbial life beneath 4 kilometers of ice could help scientists determine where to drill to get the freshest samples of frozen water without contaminating the lake.

    Do your bit to fight toxic pool pollution

    New data suggest that showering before a swim in the community pool could help limit the formation of toxic chemicals in the water.

    Journal disowns transgene report

    The journal Nature now says it shouldn't have published a report that genetically engineered corn is leaking exotic genes into the traditional maize crops of Mexico.

    Stemming the Tide

    New approaches to stopping the introduction by ships of invasive species to North American waters are beginning to show promise but have a long way to go.

    Satellites discover new Arctic islands

    Danish researchers analyzing satellite observations of remote Tobias Island, discovered in 1993 off the northeastern coast of Greenland, have stumbled upon a new group of small islands nearby.

    All Cracked Up from the Heat? Major hunk of an Antarctic ice shelf shatters and drifts away

    A Rhode Island-size section of an Antarctic ice shelf splintered into thousands of icebergs in a mere 5-week period during the area's warmest summer on record.

    Rocks in Earth’s mantle could hold five oceans

    Analysis of minerals created in the laboratory under conditions that simulate those deep within the planet suggests that the zone of rocks just outside Earth's core could hold enough water to fill the oceans five times.
