These remote controlled jets can be quite expensive, but whats really interesting is that they crash exactly like their bigger counterparts: in a huge fireball. Anyway, I guess that being a spectator at one of these events is even more dangerous! Enjoy this spectacular crash!

The most ridicoulos and mad skills on this dude. He's flying a remote controlled airplane indoors, in a gymnasium. The stunts he does will simply blow you away. Guess he doesn't have anything better to do at home. Enjoy!

People have been fascinated with explosives since ancient times. That's why fireworks are here. But sometimes you want more. This video shows the controlled destruction of explosives against several various obsolete structures. Enjoy the mayhem!

Here's a cool remote controlled truck race...but with a cool twist: the trucks fly! Yup, it's definitely cool and unexpected Enjoy!

One of the biggest remote controlled model airplanes I've ever seen. It it complete with mini turbo engines. Mount a camera and you've got an UAV. A loud one! Enjoy!

Now this is a weird race. The little RC car has only 1.5 bhp. But with a good power/weight ratio, it has stunning acceleration. Have a look at this video and be amazed of the speed it's got, and the skills of the drivers. Enjoy!

A very cool remote controlled airplane, which looks like a witch and can actually fly. Watch this guy take it out for a spin

Here's a cool remote controlled turbine powered helicopter, doing a few laps around on a field. Just a warning though...this thing is really loud...so turn down your speakers. Enjoy!

Here's a remote controlled helicopter equipped with nothing else than a rifle with live ammo. Guess, that's not for sale, huh? It would've been a great toy to have in Los Angeles ;)

Although the actual ride seems to be controlled by a human, it's still very funny to see her not being able to get up for so long! Lol. Enjoy!

This creepy looking robot is Simroid which translates as Pain Girl. This high-tech robot simulates a dental patient complete with pain noises and cavities. Of course, she is controlled by a human, which gives it the chooses the proper responses from a multitude of possibilities. Creepy stuff

I'm all against animal cruelty and such, but sometimes, these experiments can bring forward something that would benefit millions of people. I think that one such case is this. This monkey has a microchip implanted in its brain, and linked up to a robotic arm. The amazing thing is that the monkey can control the arm like an extension of its body, with incredible precision, and without any visible effort!

A stunning footage of an indoor R/C airplane performing some incredible stunts. The precision with which it's controlled, is the amazement factor...whether it's flying inches from the ground or it's doing a tail slide, it's really worth watching! Enjoy!

The switch that turns off and on to command the superconducting property of the new device is a trivial electric field. In practice, what has been done by Andrea Ankle and colleagues at the University of Geneva in the first superconducting transistors. The operation, represents a milestone of applied physics and paves the way for the development of a new generation of microchips - and therefore computers - much faster than at present. To understand how and why the device is considered so promising it must be from another discovery, made last year by the same group of university research in Switzerland and published in Science. In one study, physicists have created a single crystal in which two metal oxides (strontium titanate and lanthanum aluminate) are separated. Between these two materials, researchers have found a layer of free electrons (electronic cloud) and 0.3 Kelvin - that is just above absolute zero - traveling without any resistance. At that temperature, the crystal becomes a superconductor. Scientists have now discovered how to turn off and turn on the superconductivity of this crystal at will, or modules, simply by applying an electric field to the point of contact between the two oxides. The result is a version of superconductive field effect transistors (FET) devices known in applied physics, able to switch from one state to a semiconductor insulator, and basic digital information in electronics (the fact that the current can pass or not is used as a binary 1-0 to store information). As the field effect transistors is a semiconductor, however, it always has resistance to the passage of current. This means that the speed at which you can get the electrons when the device is "on" is limited which means heat develops beyond a certain limit. This side effect is damaging the transistor. A superconducting transistor, however, can pass electrons (and record information) much more quickly, as it does not oppose any resistance to the passage of current and, therefore, not heat. There remains the problem of extremely low temperatures required for superconductivity. A limit that research is a long time trying to overcome.

Robo4, present in the cells of the blood vessel wall, may improve or prevent the consequences of eye diseases The age-related ocular degeneration is the leading cause of blindness in people over 65 years old, and retinopathy lead to total loss of sight in most of the patients of diabetes, about 21 million in the world. In particular, the degeneration and the destabilization of the vessel wall causes many times a loss of liquid and, consequently, severe inflammation that can lead to blindness. A new protein, named Robo4, identified in cells in the wall of blood vessels, may prevent these anomalies and help reduce or even prevent various vascular diseases related to an increase. The study, conducted by Dean Li and colleagues at the University of Utah, in the United States, was published in Nature.
