    When anxiety happens as early as preschool, treatments can help

    When Molly was 10 months old, her parents took her to a Halloween party with other young families. While the other babies explored their surroundings, Molly sat and watched. She’s always been cautious, says Molly’s mom, Rachel. Early on, though, the little girl’s shyness didn’t raise red flags.

    By the time Molly turned 4, however, life was getting harder — for everyone. Even though she...

    The herbal supplement kratom comes with risks

    Kratom, an herbal supplement available at vape shops and online stores, has been linked to 91 deaths over 18 months from July 2016 to December 2017, according to a report by the U.S. Centers for Disease Control and Prevention.Those deaths made up less than 1 percent of the 27,338 overdose fatalities analyzed for the report, released online on April 12. Although small, the numbers point to...

    Dead pig brains bathed in artificial fluid showed signs of cellular life

    Scientists have restored cellular activity to pig brains hours after the animals’ death — an unprecedented feat. This revival, achieved with a sophisticated system of artificial fluid, took place four hours after the pigs’ demise at a slaughterhouse.

    “This is a huge breakthrough,” says ethicist and legal scholar Nita Farahany of Duke University, who wasn’t involved in the research. “It...

    Ketamine cultivates new nerve cell connections in mice

    Ketamine banishes depression by slowly coaxing nerve cells to sprout new connections, a study of mice suggests. The finding, published in the April 12 Science, may help explain how the hallucinogenic anesthetic can ease some people’s severe depression.

    The results are timely, coming on the heels of the U.S. Food and Drug Administration’s March 5 approval of a nasal spray containing a...

    Our brains sculpt each other. So why do we study them in isolation?

    Brains have long been star subjects for neuroscientists. But the typical “brain in a jar” experiments that focus on one subject in isolation may be missing a huge part of what makes us human — our social ties. 

    “There’s this assumption that we can understand how the mind works by just looking at individual minds, and not looking at them in interactions,” says social neuroscientist Thalia...

    When an older person’s brain waves are in sync, memory is boosted

    Nudging an older person’s brain waves into sync temporarily boosts her recall powers. After about a half hour of precisely calibrated stimulation, people were better able to mentally juggle images seen on a screen, researchers report April 8 in Nature Neuroscience.The results are the latest example of technology that aims to improve thinking by reshaping brain waves, an approach that may...

    The science of CBD lags behind its marketing

    Treatments for pain and other common health problems often fall short, leading to untold misery and frustration. So it’s not hard to understand the lure of a treatment that promises to be benign, natural and good for just about everything that ails you. Enter cannabidiol, or CBD.

    So far, the U.S. Food and Drug Administration has approved only one drug containing the chemical: a...

    The CBD boom is way ahead of the science

    A few months back, a new storefront appeared in my small Oregon town. Its shelves were packed with tinctures, jars of salve, coffee beans, bath bombs — even beard oil. This motley collection shared a single star ingredient: CBD.

    Produced by the cannabis plant, CBD is the straitlaced cousin of marijuana’s more famous component — the THC that delivers a mind-swirling high. CBD, or...

    Epileptic seizures may scramble memories during sleep

    SAN FRANCISCO — Seizures during sleep can scramble memories — a preliminary finding that may help explain why people with epilepsy sometimes have trouble remembering.

    The sleeping brain normally rehashes newly learned material, a nocturnal rehearsal that strengthens those memories. Neuroscientist Jessica Creery and her colleagues forced this rehearsal by playing certain sounds while nine...

    A single sweaty workout may boost some people’s memory

    SAN FRANCISCO — For some older people, the brain boosts from exercise can be almost immediate. Improvements in their thinking abilities after a single 20-minute bout of pedaling a stationary bike mirrored those produced by three months of regular exercise, according to a preliminary study presented March 24 at the annual meeting of the Cognitive Neuroscience Society. 

    In addition to...
