Gradually Mountain View boys continue their way to the commercial launch of the Google Glass; glasses with think revolutionize the world of technology. For months now are testing several lucky Google Glass. Announcing recently a new version of this accessory, with significant improvements. This new version is more focused on the future commercial release but still undergoing testing and will be launched first in the test program “Explorer” formed by a group of people who test fixture in order to improve it further.
Well, it seems that the new version of Google Glass is beginning to reach the hands of the early testers, who will surely be eager to try anything new that have been incorporated into the fitting and see the improvements. Google has set up an exchange program in order that the present owners of a Google Glass can change the old for the new free of charge, until next February 5, 2014.
I few days ago, we announced the phone Quechua Phone 5 shall be put up for sale in Decathlon stores. Well, in a presentation, this has been confirmed and Spain will be one of the first countries to reach the terminal, which has been manufactured by the French company Archos. This model, which will be priced at 299.95 euros in all Decathlon stores, is thought to be a record for outdoor enthusiasts because it has great resistance in one of its key strengths.
For example, it is able to withstand water splashes (IP54) and blows both the Gorilla Glass protection, as its back cover protected with rubber. Therefore, we speak of a reduced cost options offered. Panel Quechua Phone 5 has a size of five inches and in addition to offering the aforementioned protection, it should be noted that it is backlit with a brightness of 350 cd / m² (which searches you can do your best in exterior) and a resolution of 840 x 480, which is not exactly remarkable. Incidentally, the viewing angle that lets reaches 83 degrees.
It seems that Samsung is planning to launch to compete in the models is priced as aggressive. In addition, an example of this, they may be some devices that come in early in 2014. One of these could be the Galaxy Tab 3 Lite; a tablet that could cost would be around 100 euros.
Everything indicates that this device would be one more than at the beginning of the year come with the “name” Lite, among which are the Galaxy Note and Grand. They could be presented during the show Mobile World Congress held in Barcelona in February, although it is not ruled out that precisely the Galaxy Tab 3 Lite is heading a little before you land on the market in January.
It is feasible to implement under the sensor skin based on carbon nanotubes to detect nitric and able to stay there for more than year rust. Nitric oxide is one of the most important signal substances in living cells, carrying messages within the brain and coordinating functions of the immune system. In many cancer cells, their levels are abnormal. ‘s research and development team has done and Nicole Iverson Michael Strano, Massachusetts Institute of Technology (MIT) in Cambridge, USA, offers a new way of measuring the oxide nitric, and potentially other substances into the body and in real time.
The new sensor made of nanotubes can detect nitric oxide in live animals for more than one year. Sensors of this type can be implanted under the skin and used to detect and monitor inflammation, a process that produces nitric oxide. This is the first demonstration that nanosensors could be used in the body for such a long period. Sensor is made of nanotubes embedded in a gel made of alginate, a common polymer in certain algae. Once the gel containing nanotubes and is implanted under the skin of mice has been shown to remain in place and are functional for at least 400 days.
Like the Grand Canyon on our planet Earth, the Martian valley called Valles Nanedi has a serpentine path and a number of features that suggest the existence in the past of a river of liquid water in the region, as some argue scientists in a recent study seem to have solved a puzzle about the conditions, previously considered almost miraculous, allowing the existence of liquid water on the surface of the Red Planet. Many studies conducted so far on how Mars could come to possess the precious liquid in surface were confronted with an obstacle: Calculations with digital models and simulations to reconstruct the evolution of the Martian climate to the greenhouse effect, which apparently was the mechanism that held the heat required, failed to reach that state.
At least not counting only carbon dioxide and water as the main actors. Equipment Ramses M. Ramirez, James Kasting and Ravi Kopparapu, of Pennsylvania State University in the U.S., a new model has been used to show that an atmosphere with enough carbon dioxide, water and hydrogen itself could generate greenhouse needed to keep temperatures Martian surface above the freezing point. These temperatures allow liquid water to flow to the surface of Mars some 3,800 million years ago.
The enigmatic persistence of Jupiter’s Great Red Spot, a huge storm that began centuries ago and has not yet ceased, defies conventional scientific explanations. Now a specialist in geophysical fluid dynamics has developed a new model that seems to explain why the mysterious Great Red Spot on the planet has not disappeared despite the centuries since its formation. ‘s Great Red Spot on Jupiter is one of the greatest mysteries of solar system. As scientists know on fluid dynamics, this massive storm, large enough to fit inside two or three planets the size of Earth should have disappeared centuries ago.
Pedram Hassanzadeh, University Harvard in Cambridge, Massachusetts, and Philip Marcus of California at Berkeley, both universities in the United States believe they can explain the reason for the unusual persistence of the storm in the largest planet in our solar system. I response to commonly accepted theories, the Great Red Spot you should disappear after several decades after its inception. Instead, it has been there for hundreds of years. Many processes are capable of dissipating vortices like the Red Spot. The turbulence and other phenomena that occur in and around the same tend to weaken the strength of their winds.
The University of Salamanca in Spain, Researchers have designed a biopharmaceutical plant designed for the production of biological molecules that generate monoclonal antibodies with therapeutic applications in many different areas, such as cancer, autoimmune diseases and chronic inflammatory or addressing problems generating rejection of transplants. “Monoclonal antibodies are biopharmaceutical drugs that are booming in the market because they have anti-cancer applications for inflammatory diseases such as arthritis and even in the research of Alzheimer’s,” he explained told DiCYT Vanessa Ojeda Hernandez, author of the design.
Employs technology that is “multi”, ie, “we can make many kinds of monoclonal antibodies, one for cancer, one for rheumatoid arthritis, so …” he says. The plant would use “flexible” facility, so that by changing as little as possible to address these product changes. ‘s why those responsible for the initiative have opted for disposable items such as biofermentors. In tests, Vanessa Ojeda reached perform production of thousands of liters. “By the time you finish making a product here, you eliminate the bag and you put a new bag,” said pointing to the model that has been developed and is installed in a metal and carriage.
Earth was recapturing from one of the most profound shifts in their environment at two billion years ago: oxygenation of the atmosphere and oceans. This led to a series of major shifts in global bio-geochemical cycles, and resulted in a wide distribution of one of the key elements of life, phosphorus. Analyses team Aivo Lepland of NGU (Norwegian service Prospecting geological) and Richard Wirth German Research Center for Geosciences (GFZ) has made in Zaonega Training, a unique set of rocks preserved in Karelia, Russia, with an age of about two billion years, have revealed a surprising result.
The formation of the first phosphorite (phosphate-rich minerals) Earth was largely, or even entirely a phenomenon regulated by the activity of sulfur bacteria.

Radiation comes in a variety of different forms. In physics, it is seen as a process whereby energetic particles, or waves, travel through space to penetrate other materials. Not all forms of radiation are harmful, but they are all impossible to detect using human senses. Radiation can’t be seen, smelt or heard – so how do we detect it?
A number of different methods have been devised over the years to detect and measure radiation levels. Here are just three:
It was discovered in 1896 that uranium compounds could darken – or fog – a photographic plate. While working in Paris, Henri Becquerel found that the plates would be affected even when they were covered up and against the light. You can learn more about Becquerel, and other famous contributors to this scientific field, at Darvill.
This discovery has been used to help measure how much radiation has struck the film over the course of time. For workers who are exposed to areas where radiation is present, badges containing the film are worn to track the dose they are receiving each month. The badges are usually made out of different elements so that exposure to alpha, beta and gamma rays can be measured separately.
You are probably familiar with the infamous ‘clicking’ sounds these radiation detectors make. Invented by Hans Geiger in the early 1900s, the device absorbs radiation and turns it into an electrical pulse that can measured.
Argon gas fills the small metal tube of the detector. In the middle of this tube is a length of wire that is connected to an electrical current of over 400 volts. When the radiation passes through the metal tube and into the gas-filled chamber, the argon gas molecules fall towards the wire and generate a connected electrical current. The frequency of the clicking sound increases as the device absorbs more radiation.
Scintillation detectors are one of the most widely used devices by people who work in hazardous areas. Tracerco is a company that provide intrinsically safe radiation monitors that allow workers to measure the radiation dosage in challenging areas. Instead of being filled with a gas, this detector is filled with a type of salt – usually sodium iodide – that will create a small flash of light when it reacts with a radioactive photon. In order to get an accurate read-out on the electronic display, the tiny flash is amplified until it can be picked up by the detector.
The ecosystem detected data from a remote time of Earth’s past, not long after when it emerged the first life on the planet. Rebuilding the emergence of life on Earth, about 4,000 million years ago, is a challenge. The oldest sedimentary rocks on Earth where one could find some traces of that momentous chapter in the history of the planet, are not only rare, but always have been altered by hydrothermal and tectonic activity. A latest study by a team together Nora Noffke and Robert Hazen of the Carnegie Academy for Science in Washington, DC, has revealed the well-preserved remains of a complex ecosystem in a sedimentary rock about 3,500 million years old, in Australia.
The Pilbara region in Western Australia sector is one of the few geological regions of the world that allow a glimpse into the early evolution of life. Already been scientifically described microfossils of bacteria and traces of other classes, but a phenomenon known as microbially induced sedimentary structures, had not been seen before in this region. These structures are formed from “carpet” microbial (and modified surfaces colonized by microorganisms), a not very different from the typical “carpet” green today bacterial float on the surface of stagnant, smelly water mode. Team Research has scientifically examined and described several sedimentary structures induced by microbes preserved in the Dresser Formation, located in said area Pilbara.
