Rethinking surface tension

(Phys.org) —If you've ever watched a drop of water form into a bead or a water strider scoot across a pond, you are familiar with a property of liquids called surface tension.

Human eye inspires clog-free ink jet printer invention

Clogged printer nozzles waste time and money while reducing print quality. University of Missouri engineers recently invented a clog-preventing nozzle cover by mimicking the human eye.

Using lasers to vaporize tissue at multiple points simultaneously

Researchers at Vanderbilt University have developed a new technique that uses a single UV laser pulse to zap away biological tissue at multiple points simultaneously, a method that could help scientists study the mechanical ...

Nano-sensor measures tension of tissue fibres

Bacteria are able to attach themselves to tissue fibres with the aid of a 'nano-adhesive'. Just how they achieve this was investigated a few years ago by Viola Vogel, Professor of Applied Mechanobiology at ETH Zurich, using ...

Physical basis of tissue coordination uncovered

The little striped zebrafish starts out as single big cell sitting on top of the yolk. During the next 3 days, cells divide and tissues move to give the fish its final shape. But how do tissues coordinate their often-complicated ...
