Here are some projections from a private party. They are among the coolest I have ever seen. Really ingenious work! Enjoy!

Let's say you're at workm and your boss is giving you a hard time about a due date on a project. What can you do? You can't open up a can of beer and drown your sorrows. Here's a solution: have a beer, while everyone thinks it's a coke. Cool!

Here's a cool window with a projector probably behind it, and some kind of projection surface. It's an unique but also brilliant idea, which I think could catch on! Anyway, it makes for one heck of a Halloween decoration! Enjoy!

Here's a cool project, that I wish I would've made as a student: a motion detecting paintball sentry gun. Now this is what I call a great idea! This guy, actually made it to work properly, and it also has decent reaction times! Enjoy this demo video!

Here's a cool project: a personnel helicopter, that actually seems feasible to use. Although I find it cool, especially because it can be made portable, I can't stop to think that in a moment of not paying attention, or if you crash, those blades could (potentially) turn you into mince meat. Do you see this as the future of personal transportation?

A really powerful homemade railgun, fired at some household items. The power (for a homemade railgun) is incredible, and while it doesn't compare to some military projects out there, it is pretty cool! Too bad the vid is so short Enjoy!

NASA hopes that this new rover concept is the way to go into the future and it will lead towards a new way of exploring harsh environments, hopefully on other planets! Very cool! And here's an actual (smaller) project built by NASA:

Here's a tape with some of the best homemade roller coasters out of K'nex pieces. Some of them are unbelievable high, needing storage in a school's gym. Their very cool, and I think that a lot of work went into those projects!

From the first Animusic DVD. Pipe Dream has been voted one of the 50 greatest animation projects ever (by 3D World magazine).

You can probably remember a Japanese project that we featured similar to this one. If not, here is the link. Anyway this one is more advanced, and probably still largely classified in the way it functions. But yes, it opens the way to some of the greatest Sci-Fi robots you've seen on TV and dreamed about. It's now possible even to make the famous exoskeleton loader we've seen in "Alien".

This little transformer can morph from a Humvee into a robot in a few seconds. Of course, there's not much future for it in real life, but it's freakin awesome to make as a science project!

A gauss gun, works by sequentially accelerating a projectile to a desired speed by using either magnets or coils. The first video is a small demonstration of the principle behind the whole thing, by using magnets. The following videos are weapons which were homemade, and as you can see work remarkably well. So well in fact, that the US Navy will implement such weapons on its ships by 2020, after they succesfully tested an 8 Megajoule prototype.

Italian researcher Alessandra Luchini wins the first edition of "The Prize Award” with a paper of a system to identify those molecules that signal the presence of a tumor (tumor markers) that are beyond the traditional methods of investigation. To do this requires making a hydrogel containing certain microscopic nano-spheres that once inserted in the samples of blood taken for analysis diagnostic trap some markers and protect them from deterioration. "These nano-spheres, made of the same plastic as hydrated soft contact lenses are equipped with special molecules that, once in the blood, snap-specific tumor markers and incorporate them. In this way, they protect them from enzymes that would otherwise deteriorate them. Usually blood tests fail to identify precisely because these markers are destroyed prematurely, " says researcher Alessandra Luchini. "The beauty of this system," says the researcher, "is that it does not need very sophisticated tools, which is simple and economical: with one hundred U.S. dollars we can make nano-spheres for more than two hundred patients." The new method is not going to replace the standard, but acts at a stage prior to analysis by providing a better quality.

To isolate individual cells of the immune system and study the interaction in order to improve the treatment of cancer. At this will serve the new biosensor prototype developed under the project Cochise (Cell-On-CHIp bioSEnsor), supported by the European Union and coordinated by Roberto Guerrieri, professor of Electronics at the Faculty of Engineering, University of Bologna . The biological approach used to treat cancer patients consisting of interferon, interleukin-2 or other factors stimulating the growth of different cell types and able to reinforce the natural defenses of the body. But these substances are not always well tolerated. An alternative approach is to identify the immune cells able to fight cancer, cultivate them in vitro and then re-introduce them in the body. But here the problem lies in identifying and in isolating the small number of cells that are selectively able to fight cancer. The objective of the project Cochise (which is intended to last three years), is to develop a new class of biosensors capable of isolating cells (not more than 1 in 10 thousand) that are actually effective in fighting cancer cells . As the first objective was developed a prototype, used to demonstrate the possibility of controlling the flow of two individual cells and putting them in a display where you can study the interaction.

A newly discovered molecule, Isx-9, is able to make stem cells mature into brain cells. The study in Nature Chemical Biology They came across this behavior, while they were stimulating stem cells to give rise to cardiac cells, when researchers from the Southwestern Medical Center at the University of Texas at Dallas, have discovered that some of the molecules tested have matured however into neural cells. Completely random, therefore, this lead to the isolation of Isx-9, the most powerful among the compounds tested, capable, at very low concentrations, to create differentiated neurons. The study, conducted by researchers led by Jay Schneider and Jenny Hsieh was published on the number of Nature Chemical Biology. Scientists began testing 147 thousand molecules for the project in order to isolate those who could stimulate embryonic stem cells to differentiate into cardiac cells. Stunningly, American researchers have noted that five of these compounds caused the stem to rise to neurons. One of these molecules was selected because it was acting to lower concentrations of the other and was more soluble in water. This, has given life to the compound Isx-9 that has been tested on neural stem cells from the brain, particularly those of the hippo campus of laboratory animals. In the test tube, the stem, under the action of Isx-9, could form the clusters and develop the first steps towards the formation of neurons.

A new advanced thermometer, based on noise Johnson, increased by five times the accuracy of current systems After seven years of work, researchers from the National Institute of Standards and Technology (Nist), the U.S. organization for the development of technologies, have managed to build a new type of thermometer, Johnson Noise Thermometer (Jnt), defined by the same scientists a goal of thermometry, which advances to five times the current state of the art. The new device will in fact take measurements of extreme precision, never obtained so far, fundamental for basic research and for the definition of units of measurement. At the head of the project is Sam Benz, the Quantum Devices Group, which officially presented it on June 9th at a conference on measures of accuracy in Broomfield, Colorado. The new thermometer provides the temperature starting from noise Johnson (hence the name), generated by the random motion of electrons inside a resistance. This measure is directly proportional to the temperature, and the system makes it possible to reduce the error without any additional calibrations. "All measurements are electrical, and do not require volumes of gas or mechanical systems that sometimes, depending on environmental conditions, could give approximate results." says Benz, " beauty is that the measurement is also very simple to perform. "

The transfer of data will be hundred of times faster than that by radio waves. The promise is made by the first tests conducted by a German institute. Receiving images in Google Earth or photos of the Hubble telescope in real time may soon be reality. A German institute has experienced a communication system based on lasers which will transfer data at a rate one hundred times higher than that possible with radio waves. The technology was developed by researchers from the Fraunhofer Institute for Laser Technology in Aachen on the company's Tesat GmbH & Co. under a project funded by the German Aerospace Center (Dlr).
