Nano-machines achieve huge breakthrough

Everywhere I look I’m seeing that we’re on the threshold of major advances in medicine, space, technology and, especially, in the field of nano scale technologies.

A major advance in nanotechnology with far-reaching potential benefits in medicine and other fields is to be announced at this year’s BA Festival of Science in Dublin.

According to this, this and this article,

“Scientists have built molecules that can, for the first time ever, move larger-than-atom-sized objects. Constructing molecular machines capable of performing relatively large-scale mechanical tasks has never been achieved before.

Now, in an unprecedented breakthrough, chemists at Edinburgh University have used light to stimulate man-made molecules to propel small droplets of liquid across flat surfaces and even up 12° slopes against the force of gravity. This is equivalent to tiny movements in a conventional machine raising objects to over twice the height of the world’s tallest building.

This significant step could eventually lead to the development of artificial muscles that use molecular ‘nano’-machines of this kind to help perform physical tasks. Nano-machines could also be used in ‘smart’ materials that change their properties (e.g. volume, viscosity, conductivity) in response to a stimulus. They could even control the movement of drugs around the body to the exact point where they are needed.”

Connecting the Dots Podcast

Podcasting hit the mainstream in July of 2005 when Apple added podcast show support within iTunes. I'd seen this coming so started podcasting in May of 2005 and kept going until August of 2007. Unfortunately was never 'discovered' by national broadcasters, but made a delightfully large number of connections with people all over the world because of these shows. Click here to view the archive of my podcast posts.
