Nielsen yesterday released a study it conducted on the popularity of the top 10 search engines for July. As expected, Google sat atop the list, commanding more than 60 percent of the market after enjoying 16 percent year-over-year growth. Trailing behind, Yahoo and Microsoft captured 17.4 percent and 11.9 percent of the market, respectively. More importantly, both companies lost ground to Google–Yahoo witnessed an 11 percent decline, while Microsoft suffered through a 10 percent decline.

And although countless tech pundits will chime in and discuss exactly why Google has been able to run roughshod over its competition, few will point out one basic fact that is too often overlooked: Google search is designed to get rid of you as quickly as possible.

Surely, some will attribute Google’s success to its better search results or Yahoo’s management troubles or Microsoft’s poor offering, but it goes far beyond that. Search isn’t simply about relevant results or the competition. Instead, search is all about getting you to your destination as quickly as possible.

And so far, it’s quite apparent that only Google understands that basic premise.

With a new analytical technique, a fingerprint can now reveal much more than the identity of a person. It can now also identify what the person has been touching: drugs, explosives or poisons, for example.

Writing in Friday’s issue of the journal Science, R. Graham Cooks, a professor of chemistry at Purdue University, and his colleagues describe how a laboratory technique, mass spectrometry, could find a wider application in crime investigations.

The equipment to perform such tests is already commercially available, although prohibitively expensive for all but the largest crime laboratories. Smaller, cheaper, portable versions of such analyzers are probably only a couple of years away.

In Dr. Cooks’s method, a tiny spray of liquid that has been electrically charged, either water or water and alcohol, is sprayed on a tiny bit of the fingerprint. The droplets dissolve compounds in the fingerprints and splash them off the surface into the analyzer. The liquid is heated and evaporates, and the electrical charge is transferred to the fingerprint molecules, which are then identified by a device called a mass spectrometer. The process is repeated over the entire fingerprint, producing a two-dimensional image.

The researchers call the technique desorption electrospray ionization, or Desi, for short.

In the experiments described in the Science paper, solutions containing tiny amounts of various chemicals including cocaine and the explosive RDX were applied to the fingertips of volunteers. The volunteers touched surfaces like glass, paper and plastic. The researchers then analyzed the fingerprints.

Because the spatial resolution is on the order of the width of a human hair, the Desi technique did not just detect the presence of, for instance, cocaine, but literally showed a pattern of cocaine in the shape of the fingerprint, leaving no doubt who had left the cocaine behind.

“That’s an advantage that this technique would have,” said Bruce Goldberger, professor and director of toxicology at the University of Florida who runs a forensics laboratory that helps medical examiners and law enforcement. Dr. Goldberger was not involved in the research.

The chemical signature could also help crime investigators tease out one fingerprint out of the smudges of many overlapping prints if the person had been exposed to a specific chemical, said Demian R. Ifa, a postdoctoral researcher and the lead author of the Science paper.

Prosolia Inc., a small company in Indianapolis, has licensed the Desi technology from Purdue and is already selling such analyzers as add-ons to large laboratory mass spectrometers, which cost several hundred thousand dollars each.

Prosolia has so far sold about 70 analyzers, said Peter T. Kissinger, the company’s chairman and chief executive. The most sophisticated $60,000 version that would be needed for fingerprint analysis went on sale this year.

However, fingerprints are not the main focus for Prosolia or Dr. Cooks. “This is really just an offshoot of a project that is really aimed at trying to develop a methodology ultimately to be used in surgery,” Dr. Cooks said.

If a Desi analyzer can be miniaturized and automated into a surgical tool, a surgeon could, for example, quickly test body tissues for the presence of molecules associated with cancer. “That’s the long-term aim of this work,” Dr. Cooks said.

In unpublished research, the researchers have successfully tested the method on bladder tumors in dogs.

Prosolia is collaborating with Griffin Analytical Technologies, a subsidiary of ICx Technologies, on a Desi analyzer that works with a portable mass spectrometer. That product is probably a year or two away from the market, Dr. Kissinger said.

As it becomes cheaper and more widely available, the Desi technology has potential ethical implications, Dr. Cooks said. Instead of drug tests, a company could surreptitiously check for illegal drug use by its employees by analyzing computer keyboards after the workers have gone home, for instance.

It can happen if hybrid machine car still using conventional machine with fossil fuel that supported with battery, but for this wind power car which developed by a company that located in New York, USA, it really not produce emission that harm to the earth.

This car can move by using air compressed propulsion energy.

This car developed by a Formula One engineer former who work for European MDI Corporation,

For now, this wind power car is ready for prototype making phase.

After doing some agreement which for estimation with Tata Motors and some Japan Automotive Producer, MDI just give license for that new technology to Zero Pollution Motors which base in New York.

That American automotive company will produce wind power car with 6 seats for capacity.

Even more this company target for American market with price lower than US$ 18.000 for first model which will launched in 2010.

According to Technoride, Zero pollution will develop wind power car which can run until 150km/h for top speed with 800 mile distance.

Who interested? We hope this car will mass produce and for all over the world market.

For processor, IdeaPad S10 have Intel N270 1.6GHz which work on mainboard with Intel 945GSE chipset. And for GPU it using Intel Integrated Graphics GMA 950 that the graphics processing result will displayed on 10.2 inch WSVGA screen which using LED backlight System and can displays until 1024 X 600 pixels.

To support this Intel processor, Lenovo plant until 2GB for memory. But, Lenovo only equip hard disk for option to this small notebook. If using SSD it can increase durability of its battery. For this moment, customers can only satisfy with 80GB until 160GB for hard disk capacity.

Although have small size ( 250.2 x 183 x 22 mm ), but this 1.1 kg notebook have big enough keyboard, almost same with keyboard on ordinary notebook. Exactly this IdeaPad S10 have completed with 1.3 Megapixels webcam and stereo speaker.

If you interest, you can have this Lenovo notebook with US$399 for price. Certainly after you visit photo galery from this IdeaPad S10.

Engineers John Rogers of the University of Illinois at Urbana-Champaign and Yonggang Huang of Northwestern University, Chicago have created an electronic eye-shaped camera that uses a new class of electronics technology that can conform to almost any shape of a human eye. The new retina-like camera sensor uses flexible photosensitive pixels.

“Using simple mechanics principles, the researchers have produced, for the first time, electronic devices on a hemispherical surface so that they can take images much like those captured by the human eye,” said Ken Chong, advisor in the National Science Foundation (NSF) Engineering Directorate, who is one of the officers overseeing the researchers’ National Science Foundation grant, in a statement.
