Italian Designers Propose Social Bike Sharing System

In the near future it would be possible to share the bike along with your experience with Internet users. Currently the GloBike system is just a concept, but it can have a great future.

The initial idea was to support the cultural exchange among people from various communities by using a special online portal. Because bicycle represents one of the most famous eco-friendly means of transport the designers decided to include it in their project.

The new bikes can transmit information on their current location to the Globike portal. Users can use the system to access the portal and call the nearest bicycle for their use.

The system features two parts that allow the user to navigate, share and chat - one is the hardware part, represented by a device featuring a NFC chip installed on the bicycle and the other part is the web portal.

It is worth mentioning that the system represents an updated version of Freecycle, which was developed by Massimo Brugnera, Alessandro Brunello and Cristiano Giuggioli. Globike involved the cooperation of these designers with Milan-based Cristiano Giuggioli, who specializes in industrial design and 3D modeling.

Internet Giant Launches Online Flu Shot Finder Tool

This week Google released a new online tool that can track down the locations where people can get vaccinations against A(H1N1) as well as seasonal influenza in the U.S.

The new service is available at It is worth mentioning that Google's new online tool will also be available at and websites of the American Lung Association.

According to a message written by Roni Zeiger and Jennifer Haroon of Google in a blogpost, the current project is currently in its first stage, with more information about flu shots locations to come. They say that Google receives very little information on these locations. "Especially given slower than expected vaccine production, we think it's important to bring together flu shot information in a coherent manner," the message says.

Last month the California-based company expanded its flu-tracking tool, with 16 more nations being added. The tool examines local patterns in search results in order to identify the spread of the H1N1 virus and influenza. Google Flu Trends includes Russia, Japan and countries from Europe. In addition, the Internet giant provides the information at in 37 languages.

After launching the tool in November 2008, Google managed to expand Flu Trends to feature such countries as Australia, Mexico, and New Zealand. The tool estimates the number of flu-related results on its search engine and offers estimates regarding influenza outbreaks in respective locations.

First Worm Attack on Apple iPhone

Australia registered the world's first worm that infects the Apple iPhone. The worm changes the wallpaper of the iPhone to an image of Rick Astley, a pop singer of the 1980s. In addition, it generates a message that reads: "ikee is never going to give you up." The worm has been dubbed ikee and it can only influence "jail-broken" devices, meaning iPhones that had their protection mechanisms removed by the user to be able to run various programs that have not been approved by Apple.

Although the current iPhone worm is not harmful, experts believe that it could bring a new wave of malware that might have a more serious impact on the device. Mikko Hypponen, a representative of F-secure, a security firm, wrote that the developer of the iPhone worm managed to liberate a full source code of the 4 existing types of the worm. "This means that there will quickly be more variants, and they might have nastier payload than just changing your wallpaper," he wrote.

Up till now only Australia registered the circulation of the iPhone worm. This can be easily explained - the developer of the worm, known as Ashley Towns, lives in Australia. According to the 21-year-old Towns, he developed the worm to make people aware of the security issues.

The worm only affects devices that have SSH installed, which is a program that allows other phones to connect to the device and alter the system and files. The iPhone is infected in case the user did not consider changing the default password after installing SSH, reports BBC News.

As soon as the device is infected with the worm, the SSH service is disabled, which prevents re-infection. There are several comments included in the code. These messages were written by Mr. Towns to explain his motivation. One of the messages reads: "People are stupid and this is to prove it. It's not that hard guys. But hey who cares its only your bank details at stake."

To get rid of the worm the user has to change the device's password and delete a number of files. According to some estimates, today up to 10 percent of all iPhones and iPod Touches are jail-broken.

SleepBox Might Be the Most Useful Invention for Urban Commuters

A great idea was proposed by architects Goryainov A. and Krymov M. from the Arch Group. They thought about designing a rental booth that would allow travelers rest during their busy schedules.

The two architects named their booth SleepBox. The SleepBox can truly deserve the title of one of the most useful inventions for urban travelers. These boxes could be installed at decking railroad stations, airports, public and shopping centers, as well as accommodation facilities and even on streets.

One booth is quite spacious, having an area of 3.75 square meters. It includes a bed measuring 2x0.6 meters and featuring an automatic system for changing the bed linen.

The occupier can stay in the boot for several hours. The SleepBox includes a ventilation system, sound alerts in case of emergency, built-in LCD TV, WiFi and sockets that could be used to charge a mobile phone or a laptop. This can indeed be one of the most useful inventions for contemporary urban areas.

Latest Discovery: Producing Fuel From CO2 Using Engineered Microbes

Joule Biotechnologies recently stated that it managed to directly generate fuel from the abundant CO2 in the air by making use of highly engineered photosynthetic microbes.

The later thrive off of sunlight and carbon dioxide within special reactors. As a result, based on the type of organism, they are able to generate straight ethanol, diesel or a number of other hydrocarbons, informs Gas2.0.

The company's latest discovery might be considered similar to biofuels generated from algae, but it involves a completely different approach. The engineers from Joule Biotechnologies apply a beneficially different mechanism for a number of reasons, including the fact that their process does not produce biomass, there is no need to use agricultural feedstock, it can be carried out on non-arable land, it doesn't require fresh water and it generate fuel directly, which means there is no need for refinement.

It seems that Joule's latest discovery involves the use of unique genes found inside the microbes that generate the enzymes responsible for producing the molecules that can be found in diesel. After discovering the genes, it was rather easy for researchers to make other types of fuels. Up till now the production of fuels took part only in laboratory conditions. However, the company looks forward to bring their latest discovery to a pilot factory that is expected to open in 2011.

Useful Invention from US Researchers - Spray-on Solar Ink

If you like this invention then vote for it here.

Together with his team of scientists from the University of Texas, Austin, Brian Korgel, is working on probably one of the most useful inventions - a spray-on solar ink that could become a much less expensive development compared to the already popular silicon solar cells used widely nowadays.

The lead researcher explained that the team intends to create an ink or a paint that one can just spread on a certain substrate at room temperature or use a heat lamp and it will function as a solar cell.

In order to create their new invention, researchers make use of a material known as copper indium gallium selenide, shortly CIGS. The sunlight is soaked up by nanoparticles from CIGS which then transform it into electricity.

It is worth mentioning that Korgel's team is not the only one to carry out experiments with solar inks.

A similar work is currently in the development stage at the New Jersey Institute of Technology where Dr. Som Mitra is working on a solar ink material, which she believes can become a very useful invention in the near future. The scientist considers that in 5 years it would be quite common to see painted solar cells on various rooftops. Mitra's group uses a different technique to develop solar cells.

A polymer replaces CIGS nanoparticles in Mitra's experiment. The polymer is the one to produce an electrical charge. Then researchers apply a carbon-nanotube composite in order to boost the transport of electricity, reports Discovery News.

Both Korgel and Mitra believe that today more people and companies have an increased interest in green energy, which leads to the increasing cost of oil among various nonrenewable resources.

Satellite that Harnesses Solar Energy to Debut in 2010

Recently a non-profit organization for space exploration, Planetary Society, stated that in 2010 it looks forward to send its satellite called LightSail-1 into outer space. The most important fact of the project is that the satellite will be powered by solar energy, the latter being harnessed by solar sails.

The device will be much lighter than other satellites, around 11 pounds, due to the fact that it won't carry fuel. In addition, it is to be the first out of three satellites in the program that looks forward to provide evidence that solar sailing can be widely used in the field. After the launch, the satellite will stay close to the planet, but with each new mission, engineers will launch their devices further into space.

With open sails, LightSail-1 will span six meter across. The satellite is composed of three small cubes, two of which hold the sail while the third one holds the controls along with electronics. It will feature four triangle-shaped aluminized Mylar sails, each being a quarter as thick as a trash bag. It is worth mentioning that the light from the sun features protons that carry momentum. When they hit the satellite's sails, the latter push LightSail-1 further into space. The technology resembles the one we can observe on Earth when the wind conveys the momentum into the sails of a boat.

Researchers think that it is too yearly to talk about carrying humans on a LightSail craft, mainly because such task would require technology that has not yet been developed. But there's still hope. At the end of 2010 Planetary Society hopes to send LightSail-1 on a planned mission with an American or Russian spacecraft. This might not be so difficult, considering the light weight of the satellite.

The Biggest Man-Made Mountain to Be Erected Over Berlin

Can you imagine a man-made mountain that is 1,000 meters tall? That is the idea recently revealed by Jakob Tigges, a German architect. The mountain will be placed in Berlin at the site where the Tempelhof airport was located. The project is entitled "The Berg" and it is expected to be the largest man-made mountain on the planet.

The Berg is expected to attract a large number of tourists, especially those who enjoy skiing. In his manifesto, the designer says that the current project made such big German cities as Munich and Hamburg feel jealous. He says: "While big and wealthy cities in many parts of the world challenge the limits of possibility by building gigantic hotels with fancy shapes, erecting sky-high office towers or constructing hovering philharmonic temples, Berlin sets up a decent mountain."

The project is really incredible but it is still doubtful, since most designers would choose eco-friendly livable buildings over a mountain that occupies a huge territory and can be used only for outdoor sports. The Berg became very popular in a rather short period of time, with the project being mentioned in a German media and gaining huge popularity on Facebook. Tell us what you think about this project - check out the comment section below. More information is available here.

Bubblegum for Diabetics Could Replace Daily Insulin Jabs

American scientists are working on an interesting invention - a bubblegum that could deliver insulin and thus end daily jabs for people suffering from diabetes. The gum will allow people to take medicine orally. When they chew the gum, the medicine is absorbed into the bloodstream. It is worth mentioning that insulin cannot be swallowed due to the fact that it is unable to survive the journey through the digestive system since the acid bath in our stomach along with the enzymes found in the intestines destroy it.

Now a team of researchers, led by Tejal Desai of the University of California, are working on designing devices that make use of microscopic capsules that protect insulin and bring it to the bloodstream.

The capsules are so small that the patient will not notice when these are swallowed after being dissolved in the saliva. Covered in spines, the capsules stick to the gut's walls and then steadily release insulin inside, reports The Daily Telegraph. The professor is currently upgrading the capsules in order to improve their adhesion as well as their rate of supply of insulin.

This interesting invention has not yet been tested on humans. Prof. Desai is to reveal the results of the tests on humans at the annual meeting of the American Institute of Physics. The researcher believes that the gum could also be used to deliver hormones and anti-inflammatory drugs.
