A cool, yet ingeniously simple little robot, made out of LEGO, which is able to play tic-tac-toe. It scans every place on the board, and puts a piece where it thinks it's best. Brilliant!

This is a really cool video clip. It shows what a bullet filmed in slow motion can do to different objects: fruits, soda cans, bottles....It's actually quite amazing to see how they explode after the bullet passes. Anyway, enjoy this bullet slow motion video!

This guy tries to scare the garbage man, by getting into one of the garbage cans. His prank doesn't quite have the desired effect, but something else happens! Have a look! Hilarious!

Well, I know it's a war zone in Iraq, but the Americans will not be loved more, if they do this kind of thing often. I understand that they can not stop for anyone because of the great attack risk, but they could at least get a horn, and honk it when entering an intersection Does insurance cover being run over by a tank?

It takes a hole bunch of cops and a few cans of pepper spray to subdue this drunk guy. He seems to think he's a black Bruce Lee or somethin'. Anyway...it's only one way it could've ended: with him in handcuffs.

Well..if you thought the these little tin cans are a death trap...think again. They can actually protect you waaaaay better than most old cars from the early 90's. Don't forget...security comes first!

Here's a bunch of guys which can throw cans from various distances and positions into garbage bins. It's a quite of skill to manage a can throw whilst moving, make it hit a pole, and then get into the bin. Enjoy these can throw tricks.

A new instrument to simultaneously measure the magnetic field and the atomic structure of matter at the nanoscale has been developed. The applications of this are future generations of high-density memories Snapshots of the weakest and microscopic magnetic fields generated by just a few molecules of a nanometer (billionth of a meter). The researchers have obtained the S3 Center of the National Institute for the Physics of Matter (INFM-CNR) of Modena and the University of Modena . This is a scanning microscope combined with a new highly sensitive magnetic sensor. The microscope scans close with his point - made up of a few atoms - the area of the test and how it relates to the roughness with a resolution of several nanometers. Beside the point, the sensor records the magnetic field intensity, but with high detail ( millionth of a meter). In this way the researchers were able to get together for the first time, images of atomic structure and magnetic properties of a thin layer of nano-magnet on a support of silicon. "The microscope allows us to measure directly the properties of nano-molecular magnets on the surface, even at temperatures close to absolute zero, to minus 270 degrees," says Marco. "Above all," says the researcher, "it helps us to understand the magnetism on the molecular scale."

In the blood of alligators and crocodiles proteins were discovered with high antibacterial and antifungal activity. Unlike men, alligators can combat fungi, viruses and bacteria without the body being previously subjected to these micro-organisms. The researchers have demonstrated the McNeese State University and Louisiana State University who collected the blood from alligators and analyzed the white blood cells, which are the cells appointed to immune defense.

According to an American study published in Science, spending on others is the secret of happiness. The secret of happiness? Be generous. The claim is of Elizabeth Dunn of British Columbia University and Lara Aknin and Michael Norton of Harvard University, just published a study in Science, that people feel happiest when they spend for their loved ones or for purposes of charity. The researchers examined a representative sample of the national population composed of more than 630 Americans, of whom 55 percent women. The survey took into account various factors, including the "degree of happiness" perceived by volunteers and the report of this subjective value with the annual income, the average monthly expenditure, the total number of "gifts" referred to themselves and the other, and donations to charities. It is found that, regardless of income, people who spend larger quantities of money for others and for themselves, feel happier.

Using functional magnetic resonance imaging, researchers have been able to associate a brain activation pattern to the memory of an image. According to a study in Nature. Reading the thoughts of other people is not yet possible, but scientists are working on it. One tool developed by Jack L. Gallant and collaborators at the University of Berkeley (California) is able to recognize an image that a person has just seen through his brain activity. Two of the authors of the study published in Nature - Kendrick Kay and Thomas Naselaris - were submitted in person by observing the experiment at random photographs from a group of 120 during brain scans using functional magnetic resonance (fMri). The results of fMri, combined with a mathematical model, have served to associate the images neuronal activity that a person has just had before our eyes.

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.
