  • Study identifies Shisa7 gene as key driver in heroin addiction

    Study identifies Shisa7 gene as key driver in heroin addiction

    Opioid use disorder is associated with more than 350,000 deaths annually worldwide. Guided by the need for an increased understanding of critical neurobiological features of addiction, researchers have now found a unique molecular signature and genes in the orbitofrontal cortex associated with heroin-seeking behavior. A preclinical rodent model implicated a gene called Shisa7 as the key predictor. A new study in Biological Psychiatry, published by Elsevier, provides valuable insights into…

  • Scientists discover why obesity takes away the pleasure of eating

    Scientists discover why obesity takes away the pleasure of eating

    The pleasure we get from eating junk food — the dopamine rush from crunching down on salty, greasy French fries and a luscious burger — is often blamed as the cause of overeating and rising obesity rates in our society.

    But a new study by scientists at the University of California, Berkeley, suggests that pleasure in eating, even eating junk food, is key for maintaining a healthy weight in a society that abounds with cheap, high-fat food.

    Paradoxically, anecdotal evidence suggests that…

  • Highly educated people face steeper mental declines after stroke

    Highly educated people face steeper mental declines after stroke

    When someone has a stroke, it can accelerate the loss of cognitive ability over the coming years.

    Stroke survivors who have attended some level of higher education may face even steeper mental declines, according to a study led by Michigan Medicine.

    In an analysis of cognitive outcomes for more than 2,000 patients seen for stroke between 1971 and 2019, college graduates performed better on initial post-stroke examinations of global cognition, a measure of overall cognitive ability that…

    Lasso-shaped antibiotic evades standard drug resistance

    A small molecule shaped like a lasso may be a powerful tool in the fight against infectious diseases, according to a new study in Nature co-authored by University of Illinois Chicago researchers.

    Lariocidin, a peptide made by bacteria living in soil, was effective against several different microbes responsible for deadly infections. UIC researchers working with collaborators at McMaster University in Canada determined how the new antibiotic works and why the drug evades bacterial…

  • How cells respond to stress is more nuanced than previously believed

    How cells respond to stress is more nuanced than previously believed

    The body’s cells respond to stress — toxins, mutations, starvation or other assaults — by pausing normal functions to focus on conserving energy, repairing damaged components and boosting defenses.

    If the stress is manageable, cells resume normal activity; if not, they self-destruct.

    Scientists have believed for decades this response happens as a linear chain of events: sensors in the cell “sound an alarm” and modify a key protein, which then changes a second protein that slows or shuts…

    The Benzodiazepine Problem No One’s Talking About, Mainly For Women

    A silent crisis is unfolding in medicine—one that disproportionately affects women and has gone largely unchecked for decades. The overprescription of benzodiazepines, commonly known as tranquilizers, is not just a case of individual misuse; it is a systemic failure in healthcare.

    Despite well-documented risks of dependence, withdrawal complications and cognitive impairment, women continue to be…
