"The latest in download technology and best of all, practically invisible" LOL. So funny...just watch!!! "Thanks Eye Fi"

Wow. If you want to see something go bad, give a first timer a .50 caliber Desert Eagle to shoot, and then close your eyes. This is exactly what happens in this video. Ouch!

Sculptures that fit inside the eye of a needle. That's what this micro sculptor does. If with the naked eye you can't see something, get a microscope, and then you'll realise how incredible this is! Enjoy!

The asymmetry of the skull of flatfish is the result of a progressive adaptation of the species. A study in Nature The bizarre anatomy of flatfish had surprised even Charles Darwin, which had not managed to find an explanation for the asymmetry of their skull. All adult in this family - including the sole, turbot, halibut - in fact, have both eyes on the top of the head. But in fossils of fish of their progenitors, this feature was absent. The mystery of the asimmetric skull is now being revealed by a study carried out by Matt Friedman, a researcher at the Committee on Evolutionary Biology and the University of Chicago and State Department of Geology at the Field Museum and published in Nature: in the Eocene era, about 50 million years ago, there were fish with intermediate characteristics. The U.S. researcher says it is enough to review the collections of fossils preserved in museums in some European countries (Italy, France, Austria, United Kingdom) to be able to find two kinds primitive - Amphistium, described for the first time more than 200 years ago, and the Heteronectes, unknown until now - in which the eye migration is partial. "We discovered thus an intermediate stage of development of these species," said Friedman, "showing that the asymmetry of the head of the fish we know today is the result of a gradual natural evolution."

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.

Even a visual stimulus extremely short, less than millisecond, affects the decoding of information in the nervous system. The Ferrari of insects, the horsefly, a tiny acrobat who moves at high speed, has proved that even a very short visual stimulus (on the scale of milliseconds) affects decoding information in the nervous system. This was discovered by scientists in universities of Indiana, Princeton (New Jersey) and the Los Alamos National Laboratory (New Mexico), one of the largest multidisciplinary institutions in the world. A human being is unable to record the continuous change of scenery and should have a supra-sensory stimulation. But this is a fly: its nervous system processes information very quickly so that the insect can adapt to what he sees with a reaction time of 30 milliseconds. "During the flight," says Ruyter van Steveninck University of Indiana, "the horsefly must quickly analyze a number of complex information and, because of its ability to move rapidly, it is reasonable to think that the way it deciphers level sensory-motor data is optimal. We then decided to study its visual system to understand how his brain can order a continuous stream of very complex data in such an efficient way. "

Filming particles is now possible. It was done for the first time by a group of Swedish researchers using extremely short pulses of light Getting images of electrons that do not appear to "move" has been impossible because of the speed of these microscopic particles. But a group of researchers in the Faculty of Engineering at the University of Lund (Sweden) now has found a way to shoot the movement of an electron using an innovative technique that provides for the use of flash light of extremely short duration.
