Injections of nanoparticles were proved to be effective while revealing blood clots location. The developed particles contain bismuth, which is actually a toxic heavy metal. The nanoparticles are rendered harmless by use of a compound that prevents the bismuth atoms from running loose in the body. Another molecule added to the nanoparticles' surface is attracted to fibrin, a particle found only in blood clots. The molecule draws the particles to the clots, where the bismuth shows...

A new ultrasonic nozzle will use ultrasound technology to increase the cleaning efficiency of ordinary water while also reducing water use. The nozzle will differ from conventional ultrasound cleaning devices by the addition of bubbles, which will scrub the nooks and crannies of the material. The power will be set to low or high, and device will use one tenth the amount of water as a conventional pressure washer. It will also reduce the chances of contamination by putting less...

My idea is to create an application for smartphones which will use phone's GPS and accelerometers to sense and pinpoint the location of potholes. The great challenge there will be how to teach the phone to tell the difference between a pothole and a speed bump or sewer grate.

Why not develop a new lithium-ion battery able to store more energy than its predecessors without overheating? The battery will use a graphite current collector and imide salt in the electrolyte of the battery, which will increase the life of the battery as well as allowing it to withstand high temperatures. The battery will have an energy density of 225 watt hours per kilogram; 50 percent higher than the lithium-ion batteries used in electric vehicles.

The new smartphone application will be able to customize a mobile device's output to suit the specific hearing needs of the user. Since no one has the same kind of hearing loss, the application will run a simple test to identify the user's particular type of hearing loss across a range of frequencies. The software will then alter the output of the device by turning up the volume on the frequencies the user will mark as difficult to hear.

It is known that a basking shark feeds by swimming with its mouth open. The shape of the shark's body plays an important role in its efficiency as a feeder. A pressure differential is created as the shark swims, resulting in lower pressure along the shark's top and helping to draw water out of the shark's gills in a way that allows it to rely on the passive flow of water to feed. Why not design a turbine with the shark's design in mind? Water enters through the first turbine while...

The DNA of E.coli bacteria was found to be a great data storage. Data compressed into chunks can be placed in different cells and easily located later. This new method enables one gram of E. coli to store the same amount of data as 450 two-terabyte hard drives, and can even be used to store images, music, and videos.

For many, the sound of the drill is a big cause of anxiety when it comes to visiting the dentist. I have an idea to create a device which will cancel out the noise of a dentist's drill helping people overcome their fear of a check-up. This new device will allow patients to listen to music on an MP3 player, while the sound of the drill will be blanked out. Patients will still be able to hear the dentist's voice because not all sounds are to be filtered out. The device will be...

For decades, rag-pickers have been marching up and down the city's railway tracks gathering empty plastic bottles, wrappers and other garbage discarded by commuters. The solution for this has already been found in India. Central Railway engineers there modified an old engine into a massive trash can able to pull in all the garbage as it chugs along the tracks.

It was proved that the bacteria in a sheep's stomach that enable it to digest cellulose can also help clean TNT contaminated soil. The TNT breaks down completely, leaving no trace in the animal's feces. Why not plant grasses in TNT contaminated soil and set the sheep free to graze and clear the land at the same time. According to my estimations, a flock of 20 sheep could completely clear an acre of TNT residue in less than three years.
