The aircraft wings or wind turbine blades themselves fill cracks that appeared after a clash or because of aging is the hope brought by numerous research projects, one of which comes from a lead product appears sufficiently effective and inexpensive.

The search for materials that can heal cracks is particularly active and has generated a lot of work. Broadly speaking, the solution makes use of epoxy resins, ie polymer, thus trained bricks chemically linked, the
monomers. In the material, reserves intact monomers are voluntarily included. When a crack occurs, it releases the monomers that are expected to go polymerize.
Ripping will be filled by the newly formed resin and will adhere to the walls of the crack.

Easier said than done… Monomers reluctant to spontaneously polymerize and we must make a solvent, energy or a catalyst to convince them.

We must therefore include in the material infrastructure complex capable of the catalyst or the solvent, or otherwise distribute energy.

Several methods have been devised, to a sophisticated technique using carbon nanotubes and a localized melting with an electric current.

In the United States, at the University of Illinois at Urbana-Champaign, the team of Scott White and Kathleen S. Toohey, presented in June material vascularized, inspired biological tissues.

Reducing the cost to launch the industrialization

Physicists from the experience of Belle KEK laboratory in Japan have discovered a curious meson called Z. According to some, this would be a particle consisting of four quarks. Such a thing seems almost impossible under the theory of quantum chromodynamics.

Since their introduction in the world of particle physics in the early 1960's by Gell-Mann, Ne'eman and Zweig, the quarks physicists have consistently intrigued by their abnormal behavior in relation to that of other elementary particles. Yet, the theory of strong interactions dominating the world of hadrons built with them has been particularly successful in describing experiences accelerators.

However, the equations of QCD (quantum chromodynamics) describing the exchange of gluons between quarks, and responsible for the composite structure of
protons and
neutrons, are notoriously difficult to resolve because of their nonlinear structure. The fact that there was still not quite sure why quarks are confined within hadrons, although there has been much progress since the late 1960's, and it is still almost impossible to predict the mass of protons and neutrons without using computers.

Nevertheless, the theory implies quite strong that quarks can gather that paired
particle- antiparticle to form mesons, and three to train baryons.

The Japanese regulatory agency of health care products, the PMDA
(Pharmaceutical and Medical Device Agency), equivalent to the French Agency of
health security of health care products (AFSSaPS) has approved the marketing
of the first two vaccines developed and manufactured in Japan against the
avian flu H5N1 virus.

In preparation for this vaccine, Japan had established in 2005 and funded a
collaboration between the PMDA, the four Japanese manufacturers of vaccines (BIKEN
(Research Foundation for Microbial Diseases of Osaka University), the
Institute Kitasato, Denka Seiken Co and Kaketsuken) and university research
groups such as the National Institute of Infectious Diseases, IMSUT (Institute
of Medical Science, University of Tokyo) and the Research Institute for
Microbial Diseases of Osaka University .

Research using the reverse genetics engineering
technique developed by Professor Kawaoka had allowed a vaccine
is prepared from whole virus NIBRG-14 inactivated grown on eggs. NIBRG-14 is a
modified virus in the laboratory from a strain of influenza, A virus and the
H5N1 avian influenza virus is the reference of WHO. Clinical trials phase I
study showed administered in two doses separated by 3 weeks, the vaccine was
well tolerated and provided sufficient immune
protection.

A study conducted at Michigan State University's National Superconducting Cyclotron Laboratory (NSCL), with a CCD camera developed by physicists from the University of Warsaw (Warsaw University), shows images of a new form radioactivity is resting on the emission of several protons unlinked.
This is not the first time that researchers have noted the
radioactive decay of a rare isotope of iron 45 Fe in the form of exotic emission of two protons. Already in early 2000 and again in collaboration with researchers Polish, experiments conducted at the laboratory french Ganil had demonstrated that the iron core, consisting of 26 protons and 19 neutrons, could well disintegrate by issuing protons.Toutefois the exact process is not yet clearly understood. Was the issuance of protons or a single bound, but unstable, called diproton?
To find out, Marek Pfutzner and his colleagues at the University of Warsaw have therefore decided to build a CCD camera for high-performance imaging products disintegration of 45 Fe.
You should know that, unlike the iron that one usually meets on Earth, and is composed of 26 protons and 30 neutrons, this isotope is unstable. This means that the camera must be related to a room in which a beam of nuclei of 45 Fe artificially produced with the cyclotron of NSCL.

 It is called Adept Quattro. One would say a little a spider with his 4 arms of different ergonomics. Left the imagination of European brains, it is about the industrial robot the fastest manipulator of the world. Conceived by the Spanish foundation Fatronik, in collaboration with the LIRMM (French laboratory CNRS/université de Montepellier2) *, Quattro is twice faster than all the other  industrial robots of this existing type today on planet.
The secrecy holds here on the innovating solutions developed at the point by the researchers, as much on the shape of this parallel robot that on its control device.

DSM Somos launches DMX-SL 100, the first resin of stereolithography intended for the high-strength applications and for the development of direct manufacture. This product results from joint work from R & D of DSM Somos and from the DSM Research Group located at the Netherlands

This resin is characterized by its shock resistance and to the very high rupture. Its shock resistance reaches 0,71 J/cm and its module of inflection lies between 2.000 and 2.400 MPa. It offers the rigidity of materials of the ABS type with twice more shock resistance and up to 20% of elongation to the rupture moreover.

 ensures a very great shock resistance even after ageing at high temperature. Its optical and tactile properties are in addition interesting: its aspect and its touch are close to those of a thermoplastic.

With these characteristics, the supplier brings closer still a little more the stereolithography of direct manufacture, i.e. the production of plastic parts personalized without passing by a traditional process and tools. This product allows the use of the stereolithography like profitable alternative to selective sintering by laser and the vacuum casting.

The town of Rome will try out a new system of dynamic cartography at the time of its “sleepless night”. It will make it possible to the users to be informed in real time on unfolding of the event. 

After the enzymes let us gloutons, the energy bacteria! At the Ampere1 laboratory, in Lyon, directed by Laurent Nicolas, of the scientists currently work with the development of a generator of at the very least original current: a microbial fuel cell. Developed for one year by Timothy Vogel and Jean-Michel Monier, this astonishing device has been intended to reduce the cost of the waste processing: by astutely exploiting the properties of the micro-organisms present in the effluents, it could ensure part of the power supply of the stations of purification! Explanations.
To nourish itself, certain bacteria degrade the organic molecules of their environment while releasing from the electrons and the protons. From where the idea often advanced on paper to transfer these particles on electrodes in order to produce electricity on the principle of the fuel cell (CAP) 2. These “biopiles” could then feed from the autonomous or isolated systems: beacons in the mountainous or desert zones, equipment for the international space station and even robots. Problem: the current prototypes have really a too low power.

Very powerful toxic insecticide, the chlordecone, classified like cancerogenic substance at the man, poses environmental problems. In spite of a prohibition of use in France since 1990, it would have been used, until 2002, in Guadeloupe and in Martinique, to fight against the charançon in the banana plantations. Last on August 2, the president of the regional Council of the Guadeloupe pled for the creation of a parliamentary board of inquiry on the use of this pesticide in the Antilles.

It is possible to handle the conscience that the human beings of their body using a process of virtual reality have. A proof of the contribution determining of the vision in the body conscience.An experiment carried out starting from a process of virtual reality showed that it was possible to influence the conscience that the men of the limits of their own body have. A team of Swiss researchers indeed succeeded in modifying the way in which the brain perceives and analyzes the body which contains it. The principle of the experiment is simple.

The schedule of conditions of the portable systems of energy production becomes increasingly constraining. Indeed, the new sources of energy must face an increase in the electric consumption of these devices and satisfy the tendency of miniaturization of the systems. In this context, the fuel cell represents a serious alternative to the batteries whose performances (150 to 200 Wh/kg) do not seem to be able to follow the evolution of this energy demand.

In a few years, the difference in temperature between the surface of the body of an animal and that of its medium (air, water) will release sufficient energy to make function electronic instruments.

It was already possible to feed in electricity an alarm clock with vegetables. To make function a device with the body temperature between now in the field of the possible ones. The applications are without limits since it would be a question of feeding as well from the portable telephones as medical sensors (pressure, temperature, pulse) or any device whose vocation is to be in contact with the human body. Researchers coming from various institutes of industrial engineering research - measurement technique, materials, integrated circuits - Fraunhofer Company planchent on the subject.

A team of scientists shelled advertisement to have succeeded in reversing the Casimir effect, which causes the attraction of the microphone-objects between them. This discovery Of nano-engineering could improve their operation of the nanomachines.

Scientists as of the Scottish university of St Andrews announce to have discovered a new means of making leviter small objects. For that purpose, the team attacked the natural laws and succeeded in reversing the phenomenon known under the name of Casimir effect, and which pushes the infinitely small structures in general to be stuck between them by the quantum force. This discovery should solve a major problem for the scientists, that of the attraction of the small objects between them within current the nanomachines.

As opposed to what one could believe, the subject of the nucleosynthesis is still far from being closed. One still does not know with certainty from which gold comes for example, even if there is not a doubt that an important component of this core present in the galaxy comes directly from the supernovas. The nuclear astrophysicists always study the physics of the cores rich in neutrons but unstable which would be stage-keys for the nucleosynthesis of the elements heavy beyond iron by addition of neutrons according to two baptized processes “S (slow fox trot) process” and “R (fast) process”. For the first time, the spectroscopy gamma of a magnesium 36 core could be made.

The proteins are essential actors of all the processes of the alive one. For their operation, these chains of amino acids must form a well defined structure, and must thus “be folded up” correctly. The incorrect folding up of certain proteins is in the beginning various pathologies like the neurodegenerative diseases of Alzheimer and Parkinson, or the diseases implying the protein prior (insane cow, Kreutzfeld-Jacob). The knowledge of the fundamental mechanisms of the folding up and the stability of proteins, as well as kinetics of inter conversion from one state to another, thus remains a major objective in the comprehension of the molecular bases of the alive one. The spectroscopy by Nuclear Magnetic Resonance (NMR) multidimensional is the method of choice to study the structural and dynamic protein properties in solution. But the study of kinetic processes like folding up or the unfolding of proteins by this technique is limited by important times of measurement which characterize it. At the Laboratory of Magnetic Resonance Nuclear at the Institute of Structural Biology (IBS-LRMN), we succeeded in reducing times of measurement of two-dimensional spectra NMR of a few minutes to a few seconds by combining technological projections (cryogenic probes, injecting rapid) with spectroscopic developments (experiments of fast NMR). This new technique, SOFAST 2D NMR, enable us to follow the folding up or unfolding of a protein in real time with a temporal resolution of about a second simultaneously for a great number of atoms along the peptide chain.
