Age-dependent vulnerability to spatial memory interference in APP/PS1 mice
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...

Researchers found 8 common food additives linked to high blood pressure and heart disease
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.

Humans may have hidden regenerative powers
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.
Ozempic and Wegovy linked to surprising drop in violent behavior
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.

Common plastic chemical linked to lifelong anxiety in new study
Exposure to a common plastic chemical before and shortly after birth may have lasting effects on behavior. Researchers found that male rats exposed early in life to DEHP—a plasticizer used in products ranging from medical devices to toys—showed significantly higher anxiety as adults, even long after exposure had ended. The animals were more hesitant to explore open spaces and spent more time frozen in place, classic signs of anxiety in rodents.
