    Add high-fat diet to the ‘don’t’ list for pregnant moms

    WASHINGTON — There’s always new advice coming out about what pregnant women should — or should not — eat. Get enough protein. Get enough folate. Don’t eat too much sugar. But don’t go too low-carb. Don’t gain too much weight during pregnancy. Eat more nuts. Don’t drink. It’s enough to make any mom-to-be’s head spin.

    Four different animal studies presented at the recent Society for...

    After injury, estrogen may shield the brain

    WASHINGTON — Estrogen can protect the brain from harmful inflammation following traumatic injury, a new study in zebra finches suggests. Boosting levels of the sex hormone in the brain might help prevent the cell loss that occurs following damage from injuries such as stroke.

    Estrogen levels quadrupled around the damaged area in both male and female zebra finches after researchers gave...

    Breathing returns to paralyzed rats

    WASHINGTON — Paralyzed rats can breathe a sigh of relief: A new treatment can restore lung function, even a year and a half after a spinal cord injury that takes it away.

    When researchers injected a scar tissue–chewing enzyme into the rats’ spinal cords and then dialed down the animals’ oxygen intake, they could breathe easily again, neuroscientist Philippa Warren reported November 17 at...

    Areas people like to be caressed match up with nerve fibers

    WASHINGTON — Being stroked in the right place at the right speed activates specialized nerve fibers. The caresses that people rate most pleasant line up with the probable locations of the fibers on the skin, new research suggests.

    “Touch is important in terms of our physical health and our psychological well-being,” said Susannah Walker, who presented the research November 17 at the...

    Protein production prevents sleep-loss forgetfulness

    WASHINGTON — Losing sleep damages the brain’s ability to make memory-building proteins, new research in mice suggests.

    Raising protein production in one of the brain’s learning and memory centers erased the forgetfulness that comes with sleep deprivation, neuroscientist Jennifer Tudor of the University of Pennsylvania reported November 17 at the annual meeting of the Society for...

    Mold may mean bad news for the brain

    WASHINGTON – Moldy houses are hard on the lungs, and new results in mice suggest that they could also be bad for the brain. Inhaling mold spores made mice anxious and forgetful, researchers reported November 15 at the annual meeting of the Society for Neuroscience.

    Cheryl Harding, a psychologist at the City University of New York, and colleagues dripped low doses of spores from the toxic...

    ‘Bath salts’ reduce communication in rat brains

    WASHINGTON — The recreational drugs known as bath salts reduce communication between different areas of the brain in rats, new research finds. This decline may be tied to the depression and aggressive behavior that some users feel after taking the drugs.

    Compared with control animals, rats dosed with one bath salt variant had less synchronized activity, or “functional connectivity,”...

    Magnets in helmets might make football safer

    WASHINGTON, D.C. — Adding magnets to football helmets could reduce the risk of concussions, new research suggests. When two players collide, the magnets in their helmets would repel each other, reducing the force of the collision.

    “All helmet design companies and manufacturers have the same approach, which is to try to disperse the impact energy after the impact’s already occurred,”...
