Since Windows took 10 years in becoming the software that everyone wanted it to be, here's another version that promises to deliver even more, and wants to fill the gap which is currently filled by a number of software products (HyperSnap, Total Commander,..). Let's hope it gets better...if not...Ubuntu!
With the 2007 Indianapolis F1 GP approaching fast, I thought it'd be a great opportunity for all racing fans to review the qualifying lap that put Michael Schumacher in pole position last year, and provided him with an easy win for Ferrari. If the commentary bugs you, just mute the video, at the loss of engine noise
Funny
While doing a Yoga lesson with her kitty, the teacher got a surprise. The bad little kitty scratches her, in the most inappropriate way
Probably the animal that represents me the most!
WTF..?!
Disneyland might be the place to take your kids, but it seems that you have to keep an eye out for Pluto, as he can get mad and chase your kid like he wants to kidnap him. WTF?
Ouch
Probably a cable snapped when this Sukhoi Su-33 was landing, causing this crash. Luckily, the pilot ejected, as the plane went for a dive.
This guy, tried to smash a can of WD40 cleaner. The hit generated by the compression of the liquid inside the can made it explode into flames, and spread burning liquid everywhere. It's a good alternative for Napalm! So...don't try this at home!
These guys decided that there wasn't enough adrenaline in their life, so they took a canister of gas threw it on top of some dry wood and lit it on fire....the only problem was that things didn't turn out as they wished...
Amazing
This crow can be compared to Einstein in humans. It's behavior is a brilliant adaptation to the modern city. I've seen all kinds of smart behavior in ravens, but not in crows. Anyway, what he's doing is very smart but also dangerous. Good luck with that!

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.
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."
Npas4: This protein regulates the formation of inhibitory synapses between neurons.
The inhibitory activity of neurons is regulated by a particular switch. This is a protein involved in the formation and maintenance of synapses in regulating selectively switching the electrical signal between nerve cells. Its name is Npas4 and was discovered by researchers from the Children's Hospital in Boston this week to publish their study in Nature.
In particular, the protein in question is a transcription factor, that is a molecule that can activate or deactivate specific genes. Those which would be linked to Npas4 are more than 270. When the protein is produced in large quantities, we are seeing an increase in the number of inhibitory synapses on the surface of nerve cells.
But what induces the production of high levels of Npas4? According to the researchers this is a reaction to excitatory synaptic. "It is as if the same excitement triggers a program to rebalance the brain with inhibition," says Michael Greenberg, coordinator of the study, which continues: "The mice in which the protein is suppressed, in fact, have neurological problems: are anxious, hyperactive and more subject to seizures. " The discovery could help researchers in studying these disorders. Inhibition, in fact, plays an important role in brain development.
The mutation of the gene Alk would be responsible for inherited forms of cancer.
Neuroblastoma is a childhood cancer more widespread and aggressive: it attacks the autonomic nervous system during development, forming frequently in tumor masses or into the chest. A study, published in Nature and coordinated by the Children Hospital of Philadelphia (USA), indicates that mutations in the gene anaplastic lymphoma kinase (Alk) would be responsible for inherited forms of the disease.
The international group of researchers, including some of the Italian Institute for Cancer Research in Genoa, have collected genetic information of 20 families where the disease was presented in more than one occasion, by analyzing the DNA of 176 people ( of which 49 with neuroblastoma). Eight families, in which at least three individuals suffering from the disease were closely analyzed, possessed the changed Alk gene. The normal role of this gene, which expresses a transmembrane receptor, is not yet understood in depth but, according to previous studies, its alterations increase the risk of developing lymphoma or lung cancer.
The procedural memory remains imprinted in the chemical synapses. It is not the merit of a cell constant.
When we drive a car or we tie a shoe knot, we store a series of gestures that are accessed faster and automatically whenever you need that action again. It is the so-called working memory or procedural memory, whose operation resembles that of cache memory of a computer, for example, allows us to more quickly open a website already visited.
A study conducted by Gianluigi Mongillo of French Cnrs research, and Omri Barak and Misha Tsodyks the Weizmann Institute (Israel) would seem to refute the widespread belief that this type of memory is fixed thanks to a number of specific neurons. On the contrary, the procedural memory is recorded at the level of chemical changes in cells that remain after the transition pressure in nervous synapses (points of contact and communication between neurons).
Infm-Cnr and Federico II University have developed a technique ultra-miniaturized to study the behavior of red blood cells.
In the film "Fantastic Journey" of 1966, to study the physiology of the human body some scientists were miniaturized and were injected with their micro-bus, in the bloodstream. Today is, in a sense, the opposite: to understand the behavior of red blood cells reproduces the circulatory network on a device the size of a chip. The device has been developed by researchers of the center Coherentia at the National Institute for Physics of Matter (Infm-Cnr) and the Department of Chemical Engineering University Federico II of Naples. Their results were presented today at the conference "The research ideas to work" in the Corsican town.
