Metallica's popular song Enter Sandman played on a weird vibration instrument called a Kazoo. Somewhat weird, but kind of cool! Enjoy!

Some pretty amazing low level flying skills from French pilots in Africa. The first plane is a KC-135 Stratotanker, and the second is a mirage fighter. You gotta be downright crazy to do stuff like this!

Here’s a cool demonstration about how some special sand expands from a tiny amount to fifty times it’s own size. Pretty cool! Instant sand!

When you've got no snow to ski, and no money to go to Switzerland, what are you suppose to do? Just be creative! If you've got sand and an old pick-up truck you can do what these guys do: sand ski!

Well...I'll let you watch this hilarious commercial, and I won't spoil it for you by saying what brand it advertisers. Enjoy and have fun!

This is a funny video of how a training exercise can go hilariously wrong. A couple of soldiers landing on a beach got stuck in quicksand. It's even more hilarious, that after the first one gets stuck the other soldiers just keep coming. Lol..enjoy this funny soldiers video!

Who said technology and art can't live together? What human kind can build is limited solely by their imagination. I've seen before the creations of Theo Jansen, but this one, takes the cake. It's not only very beautiful, but gracious and functional, even though it has thousands of moving parts. Amazing.

When you see a giant wall of sand in the distance, seemingly touching the sky, then YOU KNOW your in deep s**t. Here's such a sandstorm in Al Asad, Iraq, transforming before your eyes night into day.

This technology is bound to make it into safer systems against car bombs! As a demonstration one traffic pole, and one truck full of sandbags, go head to head. Only one will make it out alive. Who will it be? Just watch!

The particles of cobalt-chromium can cause DNA damage even if they do not come physically into contact with the cells. The nano-particles manage to damage the DNA of cells protected by a barrier made up of cellular membranes, without physically entering into contact with the cell, but rather through a multitude of chemical signals. This was found in a study coordinated at the Bristol Implant Research Center, proving that it brings out a new risk associated with nanotechnology, but also the opportunity to exploit this behavior in an innovative way. Nano-particles are now widely used. In surgery, for example, are an integral part of prostheses and implants. The research conducted so far on the risks of nanoparticles, however, relates mainly to the effects of direct exposure, while very little is known about what can cause the indirect exposure. In the new study, researchers have wondered if a barrier device was able to protect cells from the effects of nano-particles consisting of chromium and cobalt in the tissues of the clothes and orthopedic implants. The researchers interposed a barrier between nanoparticles formed out of multilayer chromium-cobalt (in quantities thousands of times greater than those with whom we come in contact normally) and a culture of human fibroblasts (connective tissue cells). Although nano-particles have not managed to cross the membrane, the fibroblasts had DNA mutations which were ten times more than the control fibroblasts. According to scholars, the effect is due to chemical signals between the cell membrane and fibroblasts. If the lines of communication between them are broken, the rate of DNA damage returned to normal.

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.

Small robots that walk on water like insects? The kitchen table, the walls of a room or the arms of an armchair that are self-cleaning? Two phenomena that Xiao Cheng Zeng, a professor of chemistry at University of Nebraska in Lincoln (USA), considers possible in the near future, and based on the same characteristic: super hidrofobia. Thanks to the computational performance of the super computer of the Riken Institute in Japan, the researcher is able to reproduce the conditions that give the area the property is to "roll" away the drops of water. In nature this phenomenon is observed on the bristles of caterpillars or on lotus flowers, and allows insects that often are seen on ponds slip skate on water. As the authors of the study reported the caterpillars or insects skaters get the super hydrophobia surface through a "two-tier" surface which means a waxy base on which there are microscopic structures like hair, often covered in turn by smaller "hair". These gradients decrease the surface area in contact with the drop of water. The result is that the drop rolls instead of sliding, as it would be a hydrophobic surface.

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.
