  • Tiny genetic switch found to control brain balance and behavior

    Tiny genetic switch found to control brain balance and behavior

    Researchers at the Institute for Basic Science (IBS) have identified a remarkably small but critical piece of genetic code that helps determine how brain cells connect, communicate, and function. The discovery not only deepens our understanding of how the brain’s wiring is built but may also explain the origins of several neurological and psychiatric conditions.

    The study, conducted by the Center for Synaptic Brain Dysfunctions at IBS and led by Director KIM Eunjoon (Distinguished Professor…

  • How stress disrupts emotion control in people with mental health conditions

    How stress disrupts emotion control in people with mental health conditions

    New Edith Cowan University (ECU) research suggests that acute stress may impair key brain functions involved in managing emotions — particularly in people living with ‘distress disorders’ such as depression, anxiety, and borderline personality disorder.

    The study by ECU Masters student Tee-Jay Scott and Professor Joanne Dickson found that rather than enhancing mental focus in high-pressure moments, stress may temporarily disrupt executive functions — the brain’s control processes that help…

  • Study discovers DNA switch that controls TB growth, and could help unlock its antibiotic resistance secrets

    Study discovers DNA switch that controls TB growth, and could help unlock its antibiotic resistance secrets

    The bacteria that cause tuberculosis (TB) may have an “on-off switch” that lets them pause and restart growth, according to a new study from the University of Surrey and the University of Oxford. The research helps explain why TB is so hard to treat with antibiotics and could pave the way for better drugs.

    In a study published in The EMBO Journal, researchers show how Mycobacterium tuberculosis uses a reversible process called ADP-ribosylation to modify its DNA and control both replication…

  • How cholera bacteria outsmart viruses

    How cholera bacteria outsmart viruses

    When we think of cholera, most of us picture contaminated water and tragic outbreaks in vulnerable regions. But behind the scenes, cholera bacteria are locked in a fierce, microscopic war — one that could shape the course of pandemics.

    Cholera bacteria aren’t just battling antibiotics and public health measures — they are also constantly under attack from bacteriophages (phages), viruses that infect and kill bacteria. These viruses don’t just influence individual infections; they can make…

  • A potential ‘anti-spice’ that could dial down the heat of fiery food

    A potential ‘anti-spice’ that could dial down the heat of fiery food

    If you’ve ever regretted ordering a spicy meal, take note: A new study identifying molecules that suppress the heat of chili peppers hints at the possibility of adapting these compounds into an “anti-spice” condiment for food that’s too fiery to eat.

    The research helps explain differences in chili pepper pungency, or spiciness, by identifying three compounds in a range of pepper samples that chemical analysis predicted, and study participants on a tasting panel confirmed, are linked to lower…

  • Looking to cut calories? Try adding chilies, study suggests

    Looking to cut calories? Try adding chilies, study suggests

    Throwing a little heat on your meal might be an effective strategy for cutting back on calories, according to a new study led by researchers at Penn State.

    Scientists at the University’s Sensory Evaluation Center examined how increasing “oral burn” — the spicy taste from ingredients like chili pepper — affects how much food people consume during a meal. The findings, available online now and slated to publish in the October issue of the journal Food Quality and Preference, suggest that…

  • When doctors skip the numbers, patients may misjudge the health risks

    When doctors skip the numbers, patients may misjudge the health risks

    When a physician says a procedure is “rarely risky,” what does that really mean? Although terms like “common” and “unlikely” may sound descriptive enough, experts in medical decision-making suggest that leaving out numbers may be misleading for patients.

    In a paper published on April 29 in the Journal of General Internal Medicine, a team of researchers and clinicians explained that patients often overestimate risk estimates, like possible side effects or medical conditions, when given only…

  • Potential new treatment for Alzheimer’s disease, other neurodegenerative conditions

    Potential new treatment for Alzheimer’s disease, other neurodegenerative conditions

    Worldwide, more than 55 million people suffer from dementia caused by Alzheimer’s Disease (AD) and other conditions that destroy cells in the brain and nervous system.

    While there is no treatment to control or manage these neurodegenerative conditions, investigators at Case Western Reserve University, University Hospitals and the Louis Stokes Cleveland VA Medical Center have identified a new and promising drug to treat AD.

    The drug — and their approach by identifying a new target in the…

  • New factor linked to heart failure

    New factor linked to heart failure

    When the workload on the heart increases, the ventricular wall may thicken too, known as cardiac hypertrophy. This is an adaptive response that reduces pressure on the heart and maintains the activity of this vital organ. It is often a reversible process that does not cause serious effects on the structure or function of the heart, but if the factor causing cardiac overload becomes chronic, it can lead to pathological hypertrophy with more serious effects (dilatation of the ventricular…

    Scientists test in an animal model a surgical technique to improve cell therapy for dry AMD

    National Institutes of Health (NIH) scientists have developed a new surgical technique for implanting multiple tissue grafts in the eye’s retina. The findings in animals may help advance treatment options for dry age-related macular degeneration (AMD), which is a leading cause of vision loss among older Americans. A report about the technique published today in JCI Insight.

    In diseases such as AMD, the light-sensitive retina tissue at the back of the eye degenerates. Scientists are testing…
