    Lowering blood pressure may help the brain

    Keeping a tight lid on blood pressure isn’t just good for the heart. It may also help the brain. 

    People given intensive drug treatment for high blood pressure were less likely to develop an early form of memory loss, according to preliminary results from a major clinical trial. This approach reduced the rate of early memory loss, called mild cognitive impairment, by around 19 percent,...

    This colorful web is the most complete look yet at a fruit fly’s brain cells

    If the secret to getting the perfect photo is taking a lot of shots, then one lucky fruit fly is the subject of a masterpiece.

    Using high-speed electron microscopy, scientists took 21 million nanoscale-resolution images of the brain of Drosophila melanogaster to capture every one of the 100,000 nerve cells that it contains. It’s the first time the entire fruit fly brain has been imaged...

    How a variation on Botox could be used to treat pain

    Painkillers crafted with a part of the wrinkle-smoothing drug Botox provide long-term pain relief in mice.

    Researchers added the modified Botox to molecules that target pain-messaging nerve cells. Mice given a single spinal injection of the new drugs showed signs of pain relief for the full duration of the experiments, around three weeks, researchers report online July 18 in Science...

    Publicity over a memory test Trump took could skew its results

    When President Donald Trump took a mental test as part of his physical in January, the results called attention to far more than his fitness for office. (He passed with a perfect score, according to his physician.) It put a test commonly used to catch early signs of dementia in the spotlight. That publicity could lead to missed diagnoses, researchers warn July 16 in JAMA Neurology.

    The brain may clean out Alzheimer’s plaques during sleep

    Neuroscientist Barbara Bendlin studies the brain as Alzheimer’s disease develops. When she goes home, she tries to leave her work in the lab. But one recent research project has crossed into her personal life: She now takes sleep much more seriously.

    Bendlin works at the University of Wisconsin–Madison, home to the Wisconsin Registry for Alzheimer’s Prevention, a study of more than 1,500...

    Pregnancy depression is on the rise, a survey suggests

    Today’s young women are more likely to experience depression and anxiety during pregnancy than their mothers were, a generation-spanning survey finds.

    From 1990 to 1992, about 17 percent of young pregnant women in southwest England who participated in the study had signs of depressed mood. But the generation that followed, including these women’s daughters and sons’ partners, fared worse...

    The right mix of gut microbes relieves autism symptoms in the long run

    MADISON, Wis. — Giving children with autism a healthier mix of gut bacteria as a way to improve behavioral symptoms continued to work even two years after treatment ended.

    The finding may solidify the connection between tummy troubles and autism, and provide more evidence that the gut microbiome — the collection of bacteria and other microbes that live in the intestines — can influence...

    In research, detours are a key part of discovery

    For more than a century, scientists have known that abnormal clumps and tangles in the brain are the hallmarks of Alzheimer’s disease. But identifying the cause of that devastating damage has proven elusive, hampering efforts to come up with a cure for an affliction that robs memory from millions of people worldwide.

    But what if those clumps and tangles accumulated because the brain...

    Vaginal microbes in mice transfer stress to their pups

    Mouse mothers can transmit stress signals to offspring, changing the way the pups’ bodies and brains develop. Some of these stress messages get delivered during birth, scientists suggest July 9 in Nature Neuroscience.

    Researchers suspected that vaginal microbes from stressed-out moms could affect male pups in ways that leave them vulnerable to stress later in life (SN: 12/14/2013, p. 13...

    Nerve cells that help control hunger have been ID’d in mice

    Newly identified nerve cells deep in the brains of mice compel them to eat. Similar cells exist in people, too, and may ultimately represent a new way to target eating disorders and obesity.

    These neurons, described in the July 6 Science, are not the first discovered to control appetite. But because of the mysterious brain region where they are found and the potential relevance to people...
