The researchers also studied fossils of extinct fishes dating back almost 400 million years and saw evidence that some of the oldest jawed fishes had bones with joint cavities for articulated ...

They can present draining areas with wide unsealed joints or with gravel spaces or landscaping without cobblestone. Unlike other drainage pavements, the pavers will not move from their position ...

This pushes the origin of our flexible joints back millions of years. “The origin of mobile joints in our fish ancestors enabled them to move about and feed in new ways,” study authors write ...

Results from this work have the potential to elucidate a solution for effective design and management of “greener” flexible pavement infrastructure. The novel materials proposed in this research could ...
