  • Should We Take Steps to Prevent Alzheimer’s and Parkinson’s Contagion?

    One of the most intriguing new areas of research in neuroscience has to do with the discovery that proteins involved with Alzheimer’s, Parkinson’s and other neurodegenerative illnesses can contort into the wrong shape. The misshapen molecules can spread throughout the brain in a manner akin to prion diseases—the most notorious of which is variant Creutzfeldt-Jakob [...]

    Does drinking alcohol—even heavily—protect against ALS?

    Everyone knows that ALS is a very bad disease, an awareness underscored by the recent Ice Bucket Challenge. The death of neurons that results in paralysis can be caused by specific genetic mutations.  But in most cases, single genes are not the culprit. So researchers have looked for other risk factors that might play a [...]

    Coinciding with Super Bowl week, the journal Neurology just came out with a study by Boston University researchers that looked at retired professional football players, comparing the cognitive functioning of players who had started tackle football before age 12 with others who hadn’t. Here is a summary of the findings, encapsulated in an accompanying editorial [...]

    Site Survey Shows 60 Percent Think Free Will Exists. Read Why.

    We are responsible for our own actions. Of course we are. Sure about that? “I think I can?” “I think I can’t?” All philosophizing aside, the assumption that we have free will has been called into question by research that suggests our brains are deciding for us before we become conscious of the decisions streamed [...]

    Bio Bigwigs Go after Drugs for Parkinson’s, Alzheimer’s and ALS

    yumanity.2

    Lists of the biggest challenges in brain science often start—or end—with consciousness. “End” because consciousness is considered so overwhelming a hack that it merits coming last on the list—the ultimate challenge. Consciousness probably deserves its first-or-last place of preference. But there is another entry that should be on the list that is frequently  left out. [...]

    Brain Training Doesn’t Give You Smarts…Except When It Does

    Our site recently ran a great story about how brain training really doesn’t endow you instantly with genius IQ. The games you play just make you better at playing those same games. They aren’t a direct route to a Mensa membership. Just a few days before that story came out—Proceedings of the National Academy of [...]

    Bhopal at 30: Lessons Still Being Learned

    In 1989, I was working as an at editor at IEEE Spectrum when I was assigned to write a feature on Bhopal. The thirtieth anniversary of that industrial disaster that killed thousands is tonight. My article back then began: On arriving at work on Dec. 3, 1984, Rick Horner, a chemical safety engineer with the [...]

    A Mouse Experiment Suggests How We Might One Day Sleep Off Toxic Memories

    One area of brain science that has drawn intense interest in recent years is the study of what psychologists call reconsolidation—a ponderous technical term that, once translated, means giving yourself a second chance. Memories of our daily experience are  formed, often during sleep, by inscribing—or “consolidating”—a record of what happened into neural tissue. Joy at [...]

    Brainfest 2014: Will Football Players Be Tested for Magnetic Polarity as Well as Anabolic Steroids?

    Virginia Commonwealth University is not exactly known as a big football school. A former president once commented that a football team would not be fielded by VCU “on my watch.” The campus bookstore, at least at one time, has sold T-shirts with the slogan: “VCU Football, Still Undefeated.” The school now has a club team.

    Learning About Your Family’s Elevated Alzheimer’s Risk—as Early as Age 8

    A Colombian university is providing regular workshops on brain basics and genetics to grade schoolers from families who face a high risk of developing Alzheimer’s in the prime of life from a rare genetic mutation. The “talleres” set up by the University of Antioquia in Medellin attempt to prepare these youngsters for the all-too-frequent possibility [...]
