    Spermicide Flip Side: Compound may promote papillomavirus infection

    A widely used spermicide may increase a woman's risk of contracting human papillomavirus from a sex partner, a study in mice suggests. On the other hand, a thickening agent in many vaginal lubricants sold commercially impedes the virus' ability to infect female mice via their genital tracts—even in the presence of the spermicide.

    It remains to be seen whether the findings will translate...

    Dropping the Ball: Air pressure helps objects sink into sand

    Here's good news if you happen to drop something while you're strolling across a sandy section of Mars: You should be able to find what you dropped more easily than if you had dropped it into desert sands on Earth. And that's not just because of Mars' weaker gravity. Two teams of physicists have shown that a denser atmosphere, such as Earth's, makes a falling metal ball penetrate much deeper...

    Allergy Nanomedicine: Buckyballs dampen response of cells that trigger allergic reactions

    Scientists have shown that soccer ball–shaped carbon molecules, commonly called buckyballs, can block allergic responses in both human cells and mice. The findings point to a new way of treating allergies using these nanoscale particles.

    In recent years, several labs have begun harnessing the unusual physical and chemical properties of buckyballs to develop new drugs and diagnostic...

    Hidden Smarts: Abstract thought trumps IQ scores in autism

    There's more to the intelligence of autistic people than meets the IQ. Unlike most individuals, children and adults diagnosed as autistic often score much higher on a challenging, nonverbal test of abstract reasoning than they do on a standard IQ test, say psychologist Laurent Mottron of H´pital Rivière-des-Prairies in Montreal and his colleagues.

    The same autistic individuals who score...

    Bad News for Cats: Cat allergen hits all allergic people

    For people who have asthma or respiratory problems that are triggered by cats, living with Fluffy is obviously a bad idea. Now, researchers have found evidence suggesting that people who know that they have other allergies may also want to avoid the furry felines.

    Scientists who conducted a study across 14 European countries say that people allergic to irritants such as dust...
