Somewhere in the future it is possible to see flying robots flown by fruit flies! It seems there is some use for them, after all...Enjoy!
I heard that it's like this all over India not just in this particular case, and that the India road network is actually in very poor condition. I've seen a funny show on which some guy from Britain came to India to build cars with a famous Indian designer. You can see that their road network is full of potholes, but I am sure that with the right kind of money going into their road infrastructure they can improve it, and by doing so, their road safety will improve also. Let's not forget that around ONE BILLION souls live over there, so you can imagine the kind of traffic you can expect. Just have a look:

Here's a dog that can properly mark his territory: instead of peeing in one spot, he develops a method of peeing on the whole sidewalk and the street, in one continuous flow
One of my favorite game reviewer is the so called "Escapist". It's reviews, are sort, to the point, yet always (almost) hilarious. If you want an honest opinion about a game, this is the review to look for. He's latest game review is Spore. Enjoy!
I love a good game review. And nobody can top the reviews of "The Escapist". My favorite is by far that of Portal. But this one is good, also! It compares the new MMORPG "Age Of Conan" against the more popular World of Warcraft. Enjoy!
Here's a hilarious video, which I won't spoil for you. All I can say, is that this video provides an interesting exercise alternative for overweight people. Really hilarious! Enjoy!
Since today is 14th of February 2008, it's Valentine's Day. Which can also be seen as another opportunity for the flower vendors and chocolate companies to prosper on our backs. Anyway, here's a hilarious video, made just in time for Valentine's Day! . Enjoy!
If you've been drinking, like the guy in the video, you'd probably might consider taking a second look on the sign on the fence you're urinating on, making sure you won't have any surprises. Wow. That's a shocker!
Here's the real reason why at zoo's they tell you not to get too close to the animals. This guy didn't want to respect that sign, so he gets too close to the cage, and gets what he deserves. Very funny . Enjoy this vid!

Here's another cornstarch and water solution, which becomes a non-newtonian fluid.
A Non-Newtonian fluid, has properties that cannot be described by classical fluids. In this video clip, the non-newtonian fluid is a mixture of corn starch and water.
This is a followup of Pool with non newtonian fluid. As seen there non-newtonian fluids can have different properties (fluid/liquid) depending on the stress. Here is an up-to-date application for the military: Liquid Armor. Enjoy!

Amazing
The answer: a whole lot. Look at this fat little hamster munching away on carrots and sunflower seeds like a vacuum cleaner. There's nothing stopping him. Go, go, hungry hamster!
Parkour is now the new extreme urban sport. Invented in France, it's actually a form of climbing, jumping, and doing all kinds of stunts in an urban environment. The catch is that everything has to have a nice flow to it. That said, it's time to watch this cool video, and see how some of the best guys do it! Enjoy!

Small robots that walk on water like insects? The kitchen table, the walls of a room or the arms of an armchair that are self-cleaning? Two phenomena that Xiao Cheng Zeng, a professor of chemistry at University of Nebraska in Lincoln (USA), considers possible in the near future, and based on the same characteristic: super hidrofobia.
Thanks to the computational performance of the super computer of the Riken Institute in Japan, the researcher is able to reproduce the conditions that give the area the property is to "roll" away the drops of water.
In nature this phenomenon is observed on the bristles of caterpillars or on lotus flowers, and allows insects that often are seen on ponds slip skate on water. As the authors of the study reported the caterpillars or insects skaters get the super hydrophobia surface through a "two-tier" surface which means a waxy base on which there are microscopic structures like hair, often covered in turn by smaller "hair".
These gradients decrease the surface area in contact with the drop of water. The result is that the drop rolls instead of sliding, as it would be a hydrophobic surface.
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).
An enzyme that can rewind the DNA at points where the two propellers should remain separate, even fatal, causing disturbances.
The cause of some serious diseases, such as the rare immune-dysplasia of bone Schimke is a protein able to settle the two propellers of DNA at points in which they should remain separate and thus induce the expression of genes that would otherwise be idle.
Under normal circumstances the DNA presents a series of "bubbles", namely the segments in which there is space between them and raggomitolate. The unusual alignment of the two parallel strips, led by newly discovered protein, called Harp (HEPA-related protein), reactivates the expression of genes in these traits, which may in this way to start even occurrence of very serious diseases.
The enzyme is and was discovered by James Kadonaga and Timur Yusufzai, two biologists at the University of San Diego (California) authors whose research results were published in Science. Just as a zip, the enzyme flows on the tape of DNA tangles the lines and welding to the two separate entities, thereby according the traits of nucleic acid that ordinarily are designed to remain inactive. Exactly the opposite of what another enzyme, the "elicasi", which has the role to unwind the DNA during replication of the molecule, being essential for life.
The protein discovery is only the first of an entire class of enzymes candidates to be the basis of occurrence of disorders characterized by cardiac or kidney malfunction, with even fatal effects on children.
To isolate individual cells of the immune system and study the interaction in order to improve the treatment of cancer. At this will serve the new biosensor prototype developed under the project Cochise (Cell-On-CHIp bioSEnsor), supported by the European Union and coordinated by Roberto Guerrieri, professor of Electronics at the Faculty of Engineering, University of Bologna .
The biological approach used to treat cancer patients consisting of interferon, interleukin-2 or other factors stimulating the growth of different cell types and able to reinforce the natural defenses of the body. But these substances are not always well tolerated. An alternative approach is to identify the immune cells able to fight cancer, cultivate them in vitro and then re-introduce them in the body. But here the problem lies in identifying and in isolating the small number of cells that are selectively able to fight cancer.
The objective of the project Cochise (which is intended to last three years), is to develop a new class of biosensors capable of isolating cells (not more than 1 in 10 thousand) that are actually effective in fighting cancer cells . As the first objective was developed a prototype, used to demonstrate the possibility of controlling the flow of two individual cells and putting them in a display where you can study the interaction.
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.
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.
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.
