The lipids might function to push away any water beneath the spatulae, allowing them to make closer contact with the surface, said physicist and co-author Tobias Weidner of Aarhus University in Denmark. Its likely they will be able to go about 2-3 weeks, but time is of the essence. He pieced the genealogy together with Eli Greenbaum from Villanova University, by analysing six genes from 244 gecko species.

Their toe pads are covered in millions of small hair-like projections called setae, which are each about 100 m long and 5 m in diameter. Engineers envisioned robotic instruments that could climb walls or grab objects without dropping them, and rovers that could maneuver rugged terrain on distant planets. Heres why each season begins twice. For a start, it gives a better idea of the relationships between the geckos. To create their artificial gecko adhesive, the Stanford team started by making silicone microwedges, which imitated gecko hair.

Those toes that maintained contact with the surface were able to shift orientation and better distribute the load. Capillary forces are attractive forces created by the surface tension of a molecular layer of absorbed water that forms between two surfaces.
