INTRODUCTION: Healthy aging is often accompanied by a loss of hearing sensitivity and a reduced ability to understand speech in both quiet and noisy environments. From a physiological perspective, neural oscillations are thought to fundamentally contribute to parse the speech signal into meaningful units and to extract linguistically relevant information at multiple hierarchical levels. Given that syllables are essential structural elements of the speech signal that recur with quasi-rhythmic...

CONCLUSION: These findings indicate that amyloidosis is associated with reduced reliability of spatial memory performance and impaired handling of competing spatial information, particularly under conditions requiring flexible updating of overlapping mnemonic representations. The results further suggest increased vulnerability to interference-related spatial memory deficits with age. Together, these findings support the utility of the OUL paradigm for studying memory updating impairments in...

A major study of more than 112,000 people found that eating foods containing common preservatives may be linked to a higher risk of high blood pressure and heart-related diseases. Researchers tracked participants for up to eight years and discovered that people consuming the highest amounts of certain preservatives had significantly greater risks of hypertension, heart attack, stroke, and other cardiovascular problems.

Data security experts say increased oversight is needed, but researchers are struggling to comply

Rotating neuronal waves are built into brain anatomy and help coordinate far-flung regions, mouse imaging study suggests

Scientists have taken a surprising step toward unlocking regeneration in mammals, showing that the ability to rebuild complex body parts may not be lost after all—it may simply be switched off. Using a two-stage treatment, researchers redirected the body’s normal healing response away from scar formation and toward regrowth, successfully restoring bone, joints, ligaments, and tendons after amputation in animal studies.

A Rutgers study suggests GLP-1 drugs such as Ozempic and Wegovy may weaken the link between impulsive tendencies and violent behavior. The surprising finding hints that these medications could affect how people act on impulses, though researchers stress that cause and effect have not been proven.
