Weaver ants can pull harder as a team than individually, enhancing their strength through coordinated movements and sticky feet. This teamwork could provide insights into robotic design for heavy lifting. Research indicates that specific signaling pathways in mouth and face skin cells prevent scarring during healing, suggesting potential applications for scar prevention. Additionally, DNA analysis of seventh-century remains in England reveals two individuals with West African ancestry, implying greater diversity in the region's historical population than previously recognized.
Researchers found that when working together, weaver ants can co-ordinate their movements and positioning to boost the strength of their pull, nearly doubling the average force contribution of each ant.
In mouth and face skin, specialized skin cells communicate differently during healing, utilizing a signaling pathway and protein to prevent the formation of scars.
An analysis of DNA from seventh-century England reveals that two individuals had recent West African ancestry, suggesting the population was more diverse than previously thought.
