Bluetooth technology is one of the most popular forms of wireless tools used by consumers today. It is the one of the easiest ways to go hands free while talking on your cellphone or communicating through your laptop and other machines. It offers flexibility to users and is seen to continue being useful even in the years to come. It is most essential while driving. It helps to eliminate safety risks because you can talk for as long as you want without interrupting the way you drive.

There are a number of other reasons why a person makes use of a Bluetooth device. And just in case you are interested in the great offers of this technology, then why not get one for yourself? This might appear to be a challenging task, as shopping for ‘techie’ stuff can be confusing to those who are not really into it. And with the plethora of choices you have in Bluetooth headsets, picking the best one for you is not so easy. To help you decide, you have to know what features to look for.

Superior sound quality is one of the most important features you need to confirm for your device. Do not forget that you are buying this because you need it to communicate. Hence, you must see to it that you can hear and be heard well by the other party.

Another feature to look out for which is directly related to having a good sound quality is noise canceling capabilities. You have to assess carefully the device you are buying to make sure it is equipped with such a feature. Going through customer’s reviews is an effective way of determining whether you are making the right choice.

When examining your choices, you should also look into the battery life. Of course, for you to maximize its use, it has to allow long hours of talk time.

A Quick, Cheap Diagnostic Test for HIV and Other Infections

A simple microfluidics chip could improve health care in poor countries by making rapid diagnostic testing a reality.

A small plastic chip that costs just 10 cents to make can reliably diagnose HIV and syphilis within about 15 minutes. The chip, which is based on microfluidics, uses small wafers that precisely manipulate nanoliter volumes of fluid in order to carry out a sequence of chemical reactions.

This is Developed by Samual Sia and collaborators at Columbia University, the system was designed to be used in resource-poor settings. Field tests in Rwanda showed that the chip works as well as traditional laboratory-based HIV diagnostics. Sia wants to deploy the test in prenatal clinics in Africa.

Many health clinics and even city hospitals in Africa must send out blood samples to a national laboratory for processing—a process that can take days or weeks. But in poor, rural areas, where patients may have to travel days to reach a clinic, many people are unlikely to return for a second visit to get their results. Tests that give reliable results in minutes could make a huge difference by letting the physician treat the patient during the visit.

While rapid diagnostic tests for HIV and some other infections already exist, they are typically not used in poor areas of Africa because they are more complicated to read and more expensive to use. Such tests are limited to detecting a single disease per use. With Sia's chip, additional tests, such as for hepatitis or malaria, can be added to the chip without increasing the cost significantly.

To make microfluidics technology more practical to use in poor countries, Sia's team designed it to be inexpensive to make and easy to read, and then tailored manufacturing methods for those purposes. The chips are produced via a plastic injection molding process that has been optimized to create nanoscale features. The reagents for the detection reaction are stored in a tube, separated by bubbles of air, and brought into the chip with the simple pull of a syringe.

The process requires no moving parts, electricity, or external instrumentation, and it requires a very small amount of blood—about one microliter. Unlike many microfluidics devices, the results can be read without microscopes or other expensive optical systems. A simple optical sensor on an instrument that's about the size and cost of a cell phone gives the test results.

Sia's team worked with Columbia's School of Public Health, the Rwandan administrator of health, and nongovernmental health organizations to test the device in Rwanda's capital city of Kigali. As many as 8 percent of women in Kigali are HIV positive, and it can take days or weeks to get the results for HIV tests at the hospital because blood samples must be sent to an outside lab for analysis. When Sia's device was used to test for HIV, and HIV and syphilis in combination, it detected 100 percent of cases, with a false positive rate of about 4 to 6 percent—on par with standard laboratory tests. The findings were published today in the journal Nature Medicine.

Recognizing the challenge of raising funds to commercialize a technology for poor nations, Sia and two partners founded a company called Claros Diagnostics. They won venture funding to develop a device for use in doctors' offices in wealthy countries to monitor signs of prostate cancer—a device that garnered marketing approval in Europe in June. Sia's team at Columbia then adapted the technology to test for sexually transmitted diseases; in addition to HIV and syphilis and hepatitis, they are working on tests for hepatitis B and C, herpes, and malaria. While the test was developed for use in poor countries, it might ultimately find appeal elsewhere as well.

Sia's initial focus is on prenatal clinics. "If you catch the diseases in mothers, you can prevent transmission to newborns, increasing clinical impact," says Sia. According to the research, syphilis testing in mothers and pregnant women could reduce the number of years lost due to ill health, disability, or early death by 200,000 in Rwanda.

Sia and his collaborators still face a major hurdle: finding funding to develop the STD device into a commercial product. While the researchers won grants and garnered venture-capital funding to develop the technology, including money from the Gates Foundation to find the best market, they have yet to secure funds to widely implement the technology. Ironically, the Gates Foundation declined to fund the next step in development, though research showed that STD testing was the optimal market to apply the technology.

World's Most Advanced Microscope

Canadian center for Electron Microscopy has developed a new powerful microscope that is world's most powerful microscope till date. According to Gianluigi Botton, Director of Canadian center for Electron Microscopy, says that the power of this microscope can be thought as equivalent to "taking Hubble Telescope and aiming it at atomic level".
Titan 80-300 Cubed

This powerful microscope named Titan 80-300 Cubed was installed at the University early in the summer, and since then it has been put through its paces to achieve unprecedented resolution.
This microscope is so powerful that it can easily identify atoms, measure their chemical state and even probe the electrons that bind them together.
According to vice-president of Mc Master, Mr. Elbestawi this microscope will make McMaster a hub for a fast growing field.

Really Impressive Microscope

A group of international scientists who visited McMaster were really impressed by the amazing capabilities of this microscope. This microscope can help scientist to discover new things in biological and physical sciencesDean of Engineering David Wilkinson sees the microscope through another lens. Titan's ability can probe structure of solid materials to the atomic level and this will have an amazing impact on development and commercialization of new technologies from biomedical devices to water quality monitoring and improved energy storage systems.

The Cost of Microscope

This microscope has been build in Netherlands by FEI Company with a cost of about $15 million. This microscope can help to examine everyday products with its Nano details that can improve the efficiency of these products.

What This Microscope Can Do?

This microscope can be used to produce more efficient lighting and better solar cells, to study proteins and drug-delivery materials to target cancers. It will assess atmospheric particulates, and help create lighter and stronger automotive materials, more effective cosmetics, and higher density memory storage for faster electronic and telecommunication devices.

Funding the microscope

Funding for the microscope instrumentation was provided by the Canada Foundation for Innovation, the Ontario Innovation Trust, the Ministry of Research and Innovation of Ontario and the Ontario Ministry of Economic Development and Trade, through a partnership with FEI and McMaster University.

The Proof of Life at Titan

In a recent invention it has been found that there is some electrical activity at TITAN, the largest moon of Saturn. After that research, it is a hot matter of discussion in scientific community, whether there is life on Saturn or not.

Previous Beliefs and researches

According to all previous beliefs. It is almost impossible for Life to sustain on Saturn due to its extremely low temperature that is -350 degrees Celsius.

Huygens Mission of NASA

In 2005 Huygens spacecraft was send to study the clouds on Titan. It was the first spacecraft to go there. As soon as Huygens entered in the environment of Titan, force of fast winds turned it to 30 degrees. After this accident, it was not possible for Huygens to find the electrical resonance on Saturn.

Study by Juan Antonio Morente

Prof Juan Antonio Morente of University of Granada, Spain studied data collected by Huygens and found that there are clues that there may be Natural Electrical Field on the surface of Titan. This energy is same as, which started chemical energy on Earth that ultimately lead to the starting of life.

Supported Reasons for this research It has been found out that the processes that started life on earth are possible at many places in Universe out of which Saturn is one. It has been confirmed that there is a big lake of hydrocarbons on Saturn. So after earth Saturn is the second place with so much liquid present openly. In these situation if lighting occurs at Saturn, then it may lead to the birth of Atoms, which are known as the starting phase of life.
