A marshmallow factory explosion creates a shock-wave that resembles that of a nuclear bomb, in the Nevada desert, near Las Vegas.

The largest nuclear weapon ever constructed or detonated was the Russian Tsar Bomba . It was detonated at 4000 m altitude the 30th of October 1961 at Mityushikha Bay test range, on the Novaya Zemlya Island. It had a yield of 50 Megatons. Awesome power!!!

The People's Democratic Republic of Koreea might be playing with nuclear bombs, but when you go through PyongYang, you can't help but feel sad, for the people that live there. It's almost a ghost town. People are probably too hungry and miserable to go outside. Really sad!

According to Reuters, this bomb is similar in power to a nuclear detonation, but it doesn't have the contamination effects. Because it doesn't violate any treaties, it can be used freely, just as the US uses its thermobaric bombs which are very similar.

Here's a cool way to hunt for fish. Forget dynamite. You'll be gathering them up for a few days. No, really, this tests sometimes are mad, people got to think that other humans could be at the receiving end of that! In an artistic way though, it's very beautiful. Enjoy!

In the 1960 America (and Russia) begun underground nuclear tests. Not only were they trying to see how the new nuclear bombs perform, but also they wanted to see if it was possible to shape the relief with the help of underground nuclear explosions. After a few tests, the idea was droped, but the video of this underground nuclear explosion remained. Enjoy!

The Atomic Cannon detonated at the Nevada Test Site in 1953, showing the atom bomb detonation and weapon effects. It exploded with a force of 15 kilotons. At this force it is actually called a tactical atomic bomb. This video sequence is from "Trinity and Beyond - The Atomic Bomb Movie"

Twenty years after the first partially successful attempt to cold fusion, a new experiment seems to have reopened the hopes of obtaining nuclear reactions at low energy (LENR low-energy nuclear reactions). This was announced by a team of researchers led by Pamela Mosier-Boss of the Space and Naval Warfare Systems Center San Diego (California), with a study presented at the annual meeting of American Chemical Society, the first visible evidence of the production of neutrons, the particles subatomic whose presence demonstrates the atomic reaction occurred. It was 1989 when Martin Fleischmann and Stanley Pons showed that it has obtained experimentally the Cold Fusion, arousing great outcry in the scientific community. Fusion is the reaction that takes place inside of stars, their source of energy, able to reproduce in the laboratory at room temperature this process would be an amazing achievement. Further research then disappointed initial expectations: the rare attempts (for example, those of 2000 and 2002) to reproduce the results of 1989 and have not convinced the path of nuclear reaction at low energy has not proved viable as an alternative to "clean" nuclear fission, which is based on the common operation of nuclear power.

Cloned cells were transplanted into the brain of mice who suffered from this disease and they replaced sick neurons. The success of therapeutic cloning in mice. Researchers of the Sloan-Kettering Institute in New York, led by neuro-scientist Lorenz Studer, have treated the guinea pigs suffering from Parkinson with the transplantation of embryonic stem cells obtained from the skin of rodents themselves sick. The experiment, described in Nature Medicine, not only has recorded cases of rejection, but also significant improvements in the evolution of clinical pathology. The group Studer - after having caused lesions in the brains of mice that would determine the same effects of Parkinson's disease - has transferred the nuclei of cells inside the tail skin cell mouse egg "emptied" of its nucleus, through the technique known as therapeutic cloning (or Scnt, Somatic Cell Nuclear Transfer). The cloned cells, cultivated, were then developed into blastocysts. The researchers thus generated 187 lines of embryonic stem cells from 24 different mice, most of which later differentiate into neurons capable of producing dopamine.

Presented today, the Italo-Spanish computer Janus, has a high level of parallelism, in which the architecture of physical connections is established when you run the program! He was baptized Janus, as the Roman god Janus Bifronte, dual supercomputer programmability, where the programmer decides not only what instructions to follow but also, with the same lines of code, which is the exact structure of links physical on which the program should be run.
