Here's a pretty cool power plant substation exploding after it burns for a few seconds. This happened in Miami, Florida at Ives Dairy substation. The substation's transformers are in oil (for it to manage to dissipate all the heat), so when you mix hot oil with high voltage you get a spectacular boom! Enjoy!
Some clips of Thermite from Brainiac science abuse. Thermite burns at around 4000 °F (2500 °C) and can cut just about anything. Watch it destroy anything in its path! Cool.
Funny
Since Easter comes with lots of chocolate eggs and bunnies, why not kill some? Here are 3 weird ways using heat, to destroy a chocolate bunny
Here's a really funny video (for all the geeks out there) about Intel's processors energy consumption. The video was reportedly shown at an employee celebration at AMD. Funny! Enjoy!
Why run in the heat with the rest of the mob, when you can outsmart them? That dog deserves a treat for thinking outside the box!
WTF..?!
This guy is dumb enough to jump over the rail crossing barrieres without even looking. This was such a close call that the train actually clips his shoe!
I was really waiting for something bad to happen to this guy: for example, the bullets in the loader to heat enough and shoot everywhere. But it seems he got lucky
Tech
This is a video presentation by Will Wheaton in which he praises Sony's OLED TV with 1,000,000/1 Contrast ratio. OLED TV's can be as thin as 3mm. So if you're thinking of buying yourself a plasma/LCD TV maybe you should wait, because as OLED technology matures, prices for plasma and LCD TVs will plummet!
Amazing
Well, usually a piano has a heavy plate made of cast iron. I suspect these guys cheated, and took it out, as I couldn't see it anywhere. Well, at least the shredder is nice
It's an interesting experiment. I'm not completely sure it's not a fake, but it's easy enough to try at home., so you should give it a try, and let me know how it works!
Sexy
Patricia Heaton played Debra in the popular comedy TV series Everybody Loves Raymond. This sexy video of her in lingerie seems to be taken from one of the episodes. It could do with some music, but it's really hot nonetheless. Enjoy Patricia Heaton in this sexy video!
Technology and Health News
This study researched killing cancer cells with nano-magnets, with the same principle as a microwave oven.
The study of nano-particles applied to biomedicine continues to give interesting results, as research is still in its infancy. Through their work, the chemists from the university of Cagliari are now investigating some of the possibilities opened by this field. One is to use magnetic particles to convey the drugs only to the diseased cells, the other is to drive up the tumor and then force them to oscillate under the control of a variable magnetic field, thereby heating the target cells, just like a microwave oven does with the water molecules contained in food.
This second mechanism exploits hyperthermia. It appears that cancer cells can be destroyed by beeing brought to a temperature of 42.5 degrees Celsius for about half an hour.
In order arrive at the place desired, the particles must be incorporated into liposomes, hollow microspheres formed by lipid bilayers (for which reason they are called "magneto-liposomes"), which are able to overcome the barrier of cells. They must have a diameter of about 20 nanometers. Larger could indeed block blood vessels, while smaller particles may be "eaten" by macrophage cells which are in charge with the elimination of foreign bodies.
Currently, the research team is working on the synthesis of particles and study of their structural and magnetic properties. Currently these are being built in oxide of iron or iron cobalt. The latter are more manoeuvrable, because their magnetic properties depend strongly on the direction along which the field is applied to (property known as magnetic anisotropy).
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.
A highly resistant and self lubricating material has been discovered, thanks to the formation of an oxide surface that captures the water vapor
Hard as diamond and slippery as a sheet of ice. The secret of the extraordinary characteristics of Bam, a special alloy-ceramics produced by blending a mix of boron, aluminum and magnesium (AlMgB14) with titanium boride (TiB2), was unveiled by researchers of Ames Laboratory, in Iowa (Usa ), who had accidentally discovered it a decade ago.
In 1999, researchers tried to obtain a substance capable of generating electricity if overheated, when, unexpectedly, found in the hands a league owned by the exceptional and seemingly inexplicable. The Bam is tough, despite possessing a complex structure, asymmetrical and not compact. Moreover, says Alan Russel of Iowa University, it is inherently slippery. One characteristic that, according to researchers, could be due to the formation on the surface of boron oxide, which can attract water molecules present in the air.
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).
