Take for example the recent introduction of G4 Bluetooth by Cardo Systems. These little devices are basically designed for bikers so that they can converse with each other while riding on the same bike or on different bikes. Hence, even bikers also can keep in touch with each other while riding bikes. There are different types of headsets available in the market today. There are user specific headsets and you can choose the one that suits all your requirements. The following list will help you decide which one would be best suited to you and will fulfill all your needs........ ]]> http://www.blogspan.org/blogs/permalinks/2-2010/hosting-provider-for-your-website.html http://www.blogspan.org/blogs/permalinks/2-2010/hosting-provider-for-your-website.html Mon, 08 Mar 2010 15:14:24 GMT One of the reasons why a lot have been setting up their own websites either for personal or for business is that there’s just so many options to choose from these days. But sometimes, the more choices there are, the more confusing it is to actually choose the right provider. If you don’t want to spend much or to spend at all on a hosting provider, then you might be looking for something like a free hosting package. Although, there are a lot of web hosts who offer free hosting, not all of them are quite nice neither for your website nor worth your time. Some web hosts actually put annoying ads, even pop-ups on your site in exchange for the free service they provide. Your site may look very unprofessional and you’re not even going to get any share from it either. And others are just simply not capable enough of providing you a good and reliable hosting........ ]]> http://www.blogspan.org/blogs/permalinks/2-2010/stitching-together-lab-on-a-chip.html http://www.blogspan.org/blogs/permalinks/2-2010/stitching-together-lab-on-a-chip.html Mon, 08 Mar 2010 15:14:24 GMT Researchers in Australia are reporting the first use of ordinary cotton thread and sewing needles to literally stitch together a microfluidic analytical device microscopic technology that can transport fluids for medical tests and other purposes in a lab-on-a-chip.

Their study is in ACS Applied Materials and Interfaces, a monthly journal........ ]]> http://www.blogspan.org/blogs/permalinks/2-2010/genes-environment-or-chance.html http://www.blogspan.org/blogs/permalinks/2-2010/genes-environment-or-chance.html Mon, 08 Mar 2010 15:14:24 GMT Biologists attribute variations among individual organisms to differences in genes or environment, or both. But a newly released study of nematode worms with identical genes, raised in identical environments, has revealed another factor: chance. It's another source of variation for researchers to consider. "Scientists have been exploring whether organisms evolve different ways to cope with genetic and environmental variation," said author Scott Rifkin, an assistant professor of biology at UC San Diego. "This study adds random variation to that mix"........ ]]> http://www.blogspan.org/blogs/permalinks/1-2010/supercomputers-to-explore-nuclear-energy.html http://www.blogspan.org/blogs/permalinks/1-2010/supercomputers-to-explore-nuclear-energy.html Mon, 08 Mar 2010 15:14:24 GMT Ever wanted to see a nuclear reactor core in action?

A new Tel Aviv University tool could either confirm your suspicions or better yet, set your mind at rest. Prof. Eyal Ben-Dor and his Ph.D. student Dr. Sandra Chudnovsky, of TAU's Department of Geography have developed a sensor called "Dust Alert" - the first of its kind - to help families and authorities monitor the quality of the air they breathe. Like an ozone gas or carbon monoxide meter, it measures the concentration of small particles that may contaminate the air in your home. Scientific studies on "Dust Alert" appeared recently in the journal Science of the Total Environment, Urban Air Pollution: Problems, Control Technologies and Management Practices........ ]]> http://www.blogspan.org/blogs/permalinks/9-2009/dual-simulation-improves-crash-performance.html http://www.blogspan.org/blogs/permalinks/9-2009/dual-simulation-improves-crash-performance.html Mon, 08 Mar 2010 15:14:24 GMT Crash tests often produce startling results. A new simulation process which factors in deformation during production as well as preliminary damage can predict the results of a crash test more accurately than ever. There are components that save lives: if a car rolls over during an accident, the 'B-pillar' plays a key role. It forms one of the connections between the floor and roof of the vehicle and is designed to prevent the passenger cell from deforming too much. The materials from which the B-pillar is manufactured therefore need to meet very exacting requirements: to save fuel they need to be ultra-lightweight, yet at the same time need to be tremendously strong and must not break. Yet what does the optimum component actually look like? With the aid of countless experiments, simulations and crash tests, the auto industry has been getting nearer to answering this question. Now Fraunhofer scientists are providing further impetus to development........ ]]> http://www.blogspan.org/blogs/permalinks/12-2008/the-most-exciting-future-biophysics160tool.html http://www.blogspan.org/blogs/permalinks/12-2008/the-most-exciting-future-biophysics160tool.html Mon, 08 Mar 2010 15:14:24 GMT If you could wish for any capabilities in an instrument to help you with your research, what would they be? It might not be hard to come up with a useful super power that’s way out of reach of current or near-future technology, but what about something you might actually have in the next 10 or 20 ......... ]]> http://www.blogspan.org/blogs/permalinks/12-2008/healthcare-in-second-life.html http://www.blogspan.org/blogs/permalinks/12-2008/healthcare-in-second-life.html Sun, 07 Dec 2008 17:10:34 GMT I just found a playlist on Youtube that is dedicated to healthcare in Second Life, the virtual world. Numerous videos about tools for medical education and sites for patient support.
