    Folding with a little help from friends

    A chaperone protein (bottom, yellow) called SecB guides the folding of another protein (transparent) in this artist's illustration. "Interactions with chaperones are very common for all proteins," says Sander Tans of the FOM Institute for Atomic and Molecular Physics in Amsterdam, and they exert a strong influence on protein shape and function.

    But previous studies of the...

    Smells Funny: Fish schools break up over body odor

    Just an hour's swim in water lightly contaminated with a common pollutant can turn fish into rejects with an odor that causes their untainted schoolmates to shun them, researchers say.

    In a lab test, brief exposure to 4-nonylphenol (4-NP), a surfactant used in many soaps, detergents, and other products, disrupted the normal tendency of banded killifish (Fundulus diaphanus)...

    Stunting Growth: Ozone will trim plants' carbon-storing power

    Increases in low-altitude ozone predicted for the upcoming century will stifle the growth of vegetation in many regions, causing planet-warming carbon dioxide to build up in Earth's atmosphere more quickly than had been expected, a new model suggests.

    Low-altitude ozone—as opposed to the planet-protecting layer of the gas in the stratosphere—forms when the sun's ultraviolet...

    Universities seek armchair astronomers

    Nonscientists and researchers alike have a chance to see something no one else ever has—a few of the million far-off galaxies that the Sloan Digital Sky Survey has recently photographed. The price of admission: People viewing the new images online must do a little work for the astronomers in charge, classifying individual galaxies as either spiral armed or elliptical collections of stars....

    Sour Genes, Yes—Salty Genes, No

    Some people abhor broccoli, complaining about its intensely bitter taste. Others (myself included) find broccoli's flavor interesting and pleasing—decidedly, not bitter. What leads to our differing culinary opinions is the possession of, or lack of, (in my case, evidently) genes conferring a super sensitivity to bitter taste. Science has recognized such genetic differences for at least a...
