A new separation process that depends on an easily-distinguished physical difference in adhesive forces among cells could help expand production of stem cells generated through cell reprogramming. By ...

A team of researchers at Åbo Akademi University in Finland made a surprising discovery. They found that Talin-1, a protein primarily known for its role in cell adhesion at the periphery of the cell, ...

Scientists have developed a method with which they can measure the contact area between a bacterium and the surface it is 'sitting' on. Interestingly a large contact area does not necessarily mean a ...

The arrays of fine adhesive hairs or 'setae' on the foot pads of many insects, lizards and spiders give them the ability to climb almost any natural surface. Researchers have found that the different ...

(Nanowerk Spotlight) Animals that cling to walls and walk on ceilings owe this ability to micro- and nanoscale attachment elements. The highest adhesion forces are encountered in geckos. A gecko is ...

Every predator needs to catch its prey. We humans use our hands, sharks and wolves use their jaws, but a few animals like frogs use something much stranger: their tongues. To understand just how frogs ...

Portland, Ore. – As microelectromechanical systems scale down in size, common forces such as surface tension and friction become more dominant. At Sandia National Laboratories (Albuquerque), friction ...

Back in 1871, James Clerk Maxwell predicted that light exerts a force on any surface it hits. This radiation pressure was experimentally discovered some 30 years later and has since emerged as a ...

Few things are as disconcerting, or as curious, as the sight of a gecko or spider skittering effortlessly upside down along the ceiling. This ability is known to be facilitated by microscopic hairs or ...
