The study examined the small - scale mechanical behaviour of teeth from limpets using atomic force microscopy, a method used to pull apart materials all the way down to the level of the atom.

The pattern generates a small but potent amount of mechanical force that shows cells where to line up.

Instead of using uncontrolled mechanical force, this new insulated transseptal needle has a closed end that safely delivers radiofrequency energy to create a small hole in the atrial septum, allowing the needle to pass to the left atrium with increased efficacy and control.

The researchers proposed that the roaches owe their ability to make this 90 ° move to their small size and hardy exoskeleton, calculating that critters under 1 kg can rely on brute mechanical force to flip themselves from floor to wall.

«This project will enable precision measurements of the physical, chemical and biological changes that occur when cells are subjected to mechanical loading, ranging from small perturbations to high - force, high - speed impacts,» said Megan Valentine from UC Santa Barbara.
