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!

Yeah...here's the reason why they have this rule. A pretty good rule know that you think about it. But, what about medical metal parts(bolts, prosthesis, and so on)? What happens with them? Anyway, it's cool! Enjoy!

A cool video animation showing what parts an engine is made of, and how it's put together. If you're a motor freak (like me) I'm sure you'll love it. Enjoy!

Here's a funny skit from the popular show Robot Chicken in which the actual actors from Battlestar Galactica (Taminoh Pinkett, Katie Sackoff and Michael Hogan) gave their voices to their Robot Chicken counterparts! Enjoy!

Today being the international recognized Women's Day (Mother's Day in some parts), I thought I'd bring you something on that line. In this video filmed on an elevator, a thief tries to snatch the woman's purse, only to be pinned down by her superior martial arts skills (aka luck). Enjoy ;)

With global warming and such, in some parts winters seems to come a lot harder now. In this video you can see what happens in such cases when cars aren't properly prepared for winter. Enjoy!

Yes..but not as funny as their Japanese counterparts. I feel sorry for the store owners...the place looked like exactly like after a party. Brutal flash mob, eh? Sad!

There are few if any models in the world to rival the Ferrari 312PB built by Pierre Scerri. This 1:3 scale masterpiece is the real thing in every sense, from its operating 100cc 12-cylinder engine to the exact scale operating Ferrari gauges which are calibrated precisely to indicate rpm, oil pressure, water temperature and oil temperature. It took Pierre 15 years and more than 20,000 hours to build this car! He learned to make glass so he could make the exact pattern lens for the operating headlights. He learned to make rubber so he could mold his own tires. The creator of the original gearbox even came out of retirement to produce an exact 1:3 scale version for the model. Featured on Jeremy Clarkson's Extreme Machines.

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.

For the first time a gene was identified that allows the repair of damaged nerves in nematodes. The study is from Science Express. A gene that can stimulate the growth of nerve cells was first identified by researchers at the University of Utah (USA), thanks to cutting-edge experimental techniques and a huge genetic screening on a nematode (cylindrical or worm). The neurons, which in the embrio are able to regenerate, in adults have their capacity to "repair" reduced or absent. In other words, damage to the central nervous system (brain or spinal cord) and its consequences - paralysis, loss or reduction of cognitive faculties - are permanent. "In the past molecules have been identified that can inhibit the growth of neurons in different organisms," says the coordinator of research Michael Bastiani, "but their removal in the laboratory had no effect. That is why we went to look for those genes that can stimulate rather than inhibit, the regeneration of nerve. " Taking as a experimental model flat worms (Caenorhabditis elegans), biologists have searched for the genes that trigger the regrowth of motor (neurons that "command" voluntary muscles): in practice, with an experimental technique called RNA interference to "shut down ", one by one, 5000 on 20,000 genes in the DNA of worms (genes similar are also present in humans). The analysis led to the identification of dlk-1, which appears to play a key role in the regeneration of nerve tissue, and three other genes responsible for the formation of axons (parts of the neuron that conduct electrical signal). The researchers found that in nematodes, the gene dlk-1 not only triggers a chain of events known as "Map kinase" behind the growth of neurons, but also that their regeneration can be increased or decreased by stimulating the gene to produce amounts more or less high of the protein dlk-1.

An amazing material was developed by Chinese scientists which is composed of carbon nanotube films and has a possible application (among otther) to produce the world's thinnest speakers. Nanotubes, are a new carbon breed of material, which is 1000 times smaller than the width of a hair and can give sound with the "same quality of conventional speakers". This, however, does not require magnets of any sort or moving parts for that matter at all. You can easilly imagine speakers everywhere: on walls, helmets, thinner ear plugs or even on your shirt. This is possible because very thin carbon nanotube films, with the right frequency of electric currents, can emit sound. It also has a wide frequency response range and high sound pressure. It also turns out that they are practical to build, and are even stretchable. Here is a video with the actual speackers embedded in a flag!

The sense of justice and the practical idea of efficiency are encoded in different ways and in different areas of the brain. A study in Science. Giving a lot to very few, or just a little at everyone? According to a study published on this number of Science, most people follow the second choice, relying on fairness. The neurophysiologists at the University of Illinois and California Institute of Technology have succeeded, through magnetic resonance imaging, to identify which brain areas are involved in taking such decisions. Scientists have concluded that two different parts of the brain, the insula (a small area of bark MEP to the perception of physiological states) and the putamen (Part nuclei that control voluntary movement), are activated when judging respectively fairness and efficiency. A third area, the caudate nucleus, is the coordination of the first two areas.

Satb1 controls the expression of genes that control the growth of tumour mass and the formation of metastases. The discovery in Nature magazine. It is a protein the cause of the aggressiveness of breast cancer. It's called Satb1 and was already known to scientists involved because expression of T cells of the immune system. Only now it has revealed its darkest side, showing that they play a key role in the malignant form of breast cancer. Metastases, which are formed when cells are adding themselves to the tumour to invade tissues nearby and colonize other parts of the body, represent the advanced stage of the disease. Researchers have now discovered that the cells of the breast cancer need their protein Satb1 to become metastatic. The study has just been published in Nature.
