For allergy sufferers, the pollination period is a tough time, whereas for plants it is the opportunity to reproduce: in addition to the wind, insects, in particular, carry pollen from one flower to another to pollinate them. ...

Light driven movement is challenging in nonliquid environments as micro-sized objects can experience strong dry adhesion to contact surfaces and resist movement. In a recent study, Jinsheng Lu and co-workers at the College ...
The cytoskeleton is a structure that not only helps cells maintain their shape and internal organisation, but also enables them to perform functions like movement and migration to sites far from the place where they originated. ...

Hydrogels are commonly used as biomaterials for applications in biomedicine due to their biocompatibility. However, the relationship between biological cells and the hydrogel surface is still unclear and the existing parameters ...
Ludwig-Maximilians-Universitaet (LMU) researchers in Munich, Germany, have characterized the physical mechanism that enables a widespread bacterial pathogen to adhere to the tissues of its human host.

Many geckos inhabit trees, often living high in the canopy. Relying on their incredible adhesive strength to help them break their fall, they jump from trees, and land on either leaves or relatively smooth tree trunks. How ...

In extreme slow-motion, a molecule of medicine entering a cell receptor would look a little like a Soyuz space capsule docking at the International Space Station. It would brake here, boost there; rotate, translate and then, ...
