Goodbye, cavities? New gel could regrow tooth enamel

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.

Scientists discover the hidden brain switch that assigns bees their jobs

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.
