INTRODUCTION: Fidelity of detailed information retrieved from long-term memory (LTM) declines in aging due to changes affecting learning and remembering processes. Such behavioral deficits correspond with functional alterations in the hippocampal formation. However, it is unclear whether age-related decline in high-fidelity retrieval alters functional connections between hippocampal and cortical regions.

Researchers have developed a fluoride-free gel that could help rebuild damaged tooth enamel, something the body cannot naturally replace once it is lost. Inspired by the proteins that guide enamel formation in infancy, the gel fills microscopic cracks and draws calcium and phosphate from saliva to grow a new mineral layer that closely matches healthy enamel.

A plant-derived compound reduced swelling, inflammation, and joint damage in rats with rheumatoid arthritis. It also helped rebalance immune activity and improve the way certain fats were processed in the body. Researchers say the findings could lead to a new approach for treating the disease.

Researchers found that specific brain circuits help decide which jobs bees perform as they age. When those circuits were switched off, older worker bees began caring for the queen again instead of carrying out their normal later-life duties. The findings reveal that a bee colony’s complex division of labor may be guided by neural switches hidden inside each bee’s brain.
