The aquatic bacterium Caulobacter crescentus cancome, quite literally, to a sticky end. As Peter H. Tsang and colleagues report (Proc. Natl Acad. Sci. USA 103, 5764–5768; 2006), the bacterium’s long, tail-like anchor sticks it so tightly to a supporting surface that it often tears apart when a detaching force is applied, rather than relinquishing its grip. The adhesion is thought to be the strongest of biological origin yet discovered......The holdfast enables the bacterium to remain stuck to the surface even in strong jets of water, and Tsang et al. calculate that, were it to cover an area of 1 cm 2 , it could support a weight of 680 kg, even on a wet surface. - NATURE|Vol 440|27 April 2006
Wow! This man was really amazing. Thank you for that invention. I am pretty sure that this thing will hit all the market world wide. Got to go! I need to write more of my custom essays.
