Swimming is a Drag for Bacteria, Brown Physicists ExplainImagine yourself swimming in a pool: It's the movement of your arms and legs, not the viscosity of the water, that mostly dictates the speed and direction that you swim. For tiny organisms, the situation is different. Microbes' speed and direction are subjected more to the physical vagaries of the fluid around them. “For bacteria to swim in water,” explained Jay Tang, associate professor of physics at Brown University , “it's like us trying to swim through honey. The drag is dominant.” |
This image shows how opposite rotations of the head and tail of the single-celled microbe Caulobacter crescentus creates drag, which helps dictate its swimming direction in a fluid.

Nano Conference: ‘Innovations in Textiles 2009’
Smart, Nano and Technical Textiles for Medical, Industrial and Clothing Applications
18 -19 March 2009: The Royal College of Physicians, London, UKThe Institute of Nanotechnology has previously organised three international conferences on textiles, providing an international platform where a diverse community of professionals from industry, academia and fashion can come together to share information, research findings and practical experiences – ranging from nano to smart textiles.
Building on the success and popularity of previous textile conferences the IoN is organising a further conference at The Royal Society in London on March 18th – 19th 2009 on this subject, bringing together multiple disciplines and various technologies and developments in the textiles arena. The conference will have an application side, as to where textile developments can be used by various industries, as well as keeping the audience up to date on the latest technologies and ideas being developed.
CALL FOR PAPERS - Authors are invited to submit papers for oral and poster presentations.
Abstracts for presentations should be emailed to: gemma.mcculloch@nano.org.uk

Drug Delivery Using Nanotechnologies:
Technologies, Markets and Competitive Environment
|
Drug delivery commands a sizeable proportion of the overall pharmaceutical market, approximately 15% or some US $109 billion in 2008. It is also expected to grow at a faster rate than the overall pharmaceutical market over the next 4 years.
The reason? Extending patent life for existing drugs and offering new alternatives for delivery, in particular the peroral route. In all of this nanotechnology is a major enabler.
This report provides a comprehensive overview of these new technologies and a market analysis of opportunities to 2012. It concludes with a description of emerging companies in this exciting and fast-developing field. |
