Oh, yes! One of the most popular games of all times, is coming out soon! To be more precise it's announced release date is: 10.16.07 . Only 6 months to go, but for the long wait, here's the official Grand Theft Auto 4 trailer to get you going.
Tech
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.
Amazing
Artist Willard Wigan creates ultraprecision. This is precision work done by people and seems seems to have surpassed even machinery in the kind of details this guy is able to create. Does anyone want a statue of liberty sculpture that can fit in the ear of a needle?
This guy can pop champagne corks with amazing accuracy. He can aim the cork so precisely, that he's able to blow out candles with it. The slow motion replay shows it clearly. Simply amazing!

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.
The use of an organic material has been put in place a structure capable of transmitting data at rates eight times higher than those of traditional devices .
The study of materials capable of transmitting data at ever higher speeds is the constant challenge of the technology of optical communications. The use of a new organic material, tested by a team of U.S. and European research coordinated by Ivan Biaggi of Lehigh University (United States), has enabled to achieve data transfers much higher than that obtained so far with traditional devices.
The novelty lies in the combination of structures in silicon with organic material, identified by the initials Ddmebt . This is essentially a kind of "nonlinear" device, able to change its molecular structure to the passage of light, making it propagate at high speed. To minimize interference with the passage of data, researchers have vaporized the organic material and the deposit left on the rails of silicon and in the spaces between them. In this way, explain the authors, the molecules are deposited "like snowflakes", forming a highly homogeneous plastic. It is precisely in the interstices between the rails of silicon, filled with new material, that the light passes at high speed, allowing you to transmit data up to 170 Gigabit per second (with the traditional structures, which consist only of silicon, you can reach a maximum speed around 20-30 Gigabit per second). Combining silicon with an architecture was needed to channel and confine the flow of light within very small spaces (the guide of silicon is separated by a few tens of nanometers).
The ventral striatum, a part of the brain already known to be associated with rewards and unexpected stimuli, is the center of our desire for adventure. The research in Neuron.
A group of researchers from the Wellcome Trust Centre for Neuroimaging at the University College of London has identified the area of the brain directly linked to our desire for adventure. Or, more precisely, our propensity to live new experiences and to experience what we do not know.
For the study, published in Neuron, researchers have developed a test: the participants were presented a series of images associated with different sums of money put into a premium, and were asked to guess which of the sums was higher. Although the volunteers easily could identify the image associated with richer rewards, when it was introduced a new figure, all of them tended to choose the latter rather than those already known with secure profits. Through magnetic resonance imaging, neuroscientists have noticed that the area of the ventral Striatum (an area of the brain already known to be associated to receive a reward and unexpected stimuli) was particularly active when participants opted for the novelty.
Particles in a confined microscopic space, move in a coordinated manner and can be manipulated and observed with a precision never achieved.
A nano-trap can be imagined as a tube the size of a billionth of a meter in which electrons are closed to study their behavior. Thus, scientists from the centers of the Italian Institute for physics of matter of Cnr "S3", Modena and "Nest" of Pisa in collaboration with Columbia University in New York, were able to observe with great precision the behavior of a quartet of electrons confined in one of these structures. Result: the particles move in a coordinated manner and with precise frequencies and can be manipulated. The study was published in Nature Phisics.
As it is known, the physics of the matter the size of an atom or less follows different laws than those of classical physics. According to these principles, which fall in quantum physics, the behavior of particles such as electrons can not be described as we are used to (for larger bjects),but it is outlined mainly in terms of probabilistic forecasts.
The technique developed by Cnr made it possible to determine the frequency of vibrations of particles through the use of a beam of laser light. The electrons in a nano-trap can only move in a coordinated manner and in accordance with the laws of quantum mechanics, vibrate at frequencies well defined that, thanks to this method, was possible to measure with unprecedented precision.
An improvement in dating techniques with argon-argon allows us to place more correctly the extinction of large reptiles.
When did the dinosaurs become extinct? 65.5 million years ago, more or less 300 thousand years. This is the answer, or at least it was until yesterday. Thanks to a more refined timing technique, researchers from Berkley, California, have reduced by nearly 10 times the range of error, identifying with extreme precision the "moment" in which dinosaurs were extinct, which matches the passage between the era of geological Cretaceous and the Tertiary. The new answer is 65.95 million years ago, with a margin of error of only 40,000 years.
For the first time there was a negative charge exactly equal to 25 percent of that unit. Research in Nature magazine.
Since the electricity comes from the transport of electrons, it is logical to expect that the smallest load that can be transported is equal to the charge of a single electron. Under specific conditions, it is possible to observe portions of this fundamental unit. Even in these conditions, however, there have been observed only odd fractions of charge: third, fifth, seventh. In the last issue of Nature it was published the existence of a quasi-particle with a charge corresponding exactly a quarter of that of an electron.
In particular, these unique elementary particles, which have been precisely called "quasi-particles" to their particular nature, are formed when electrons are confined in a two-dimensional system, which forces them to interact strongly with each other. It is known that when a flow of electrons is confined in a two-dimensional plan of a semiconductor and it is applied simultaneously in a strong magnetic field perpendicular to this plane, the electrons have unusual quantum properties. In a research just published in Nature, in an electron gas, two-dimensional and ultra-pure, were detected within the fluid vortexes charges carrying exactly one quarter of the charge of an electron.
New mechanisms based on mercury and aluminum allow an accuracy ten times higher than the current systems.
New generation atomic clocks have been developed at the National Institute of Standards and Technology (Nist), an international collaboration which includes Luke Lorini also of the National Research Metrologica (Inrim) in Turin. The research appeared in Science magazine, and showed the ability to measure frequencies, and thus time, with 17 significant digits, reaching an unprecedented accuracy. The two new atomic clocks are based on atoms of mercury and aluminum. The first system had already been submitted in 2000, but the current version is definitely improved, the mechanism based on aluminum represents a completely new system.
