September 20, 2011

In a press conference, the scientific coordinating the project HIVACAT, Christian Brander, explained that “now we proceed to test the effectiveness of the vaccine in rabbits and pigs, although the first phase of human study will begin within two years, after checking that it is completely safe.”

“There are still many obstacles to overcome, since the results are good but not definitive, and among the great difficulties the fact remains is that HIV is a virus with a great capacity for mutation.”

This project consists of ‘an investigation of the AIDS vaccine, which succeeded in identifying a promising HIVACAT vaccine immunodeficiency virus (HIV), after obtaining positive results in clinical trials with mice’.

The International Space Station (ISS) managed to collect thousands of images of Planet Earth in just 60 seconds.

Science professor James Drake spliced images of the ISS, which travels about 220 miles above Earth’s surface, to achieve what became a sensation on the web.

Drake used the images from the Gateway to Astronaut Photography of Earth, so everyone can enjoy the breathtaking view of North and South.

The film was uploaded on September 15 and attracted around 50,000 views on YouTube, begins in the Pacific Ocean and moves over North America and South America before going into the light of day near Antarctica.

Some cities and places of interest are: Vancouver Island, Victoria, Vancouver, Seattle, Portland, San Francisco, Los Angeles, Phoenix, some urban areas in Texas, New Mexico, Mexico City, the Gulf of Mexico and the Peninsula Yucatan.

You can also see the Pacific Ocean and countries such as Guatemala, Panama, Colombia, Ecuador, Peru, Chile, and the Amazon.

The images include the Earth’s ionosphere (thin yellow line) and stars of our galaxy.

United States, September 15, 2011

Through the Kepler mission, NASA scientists made the first discovery of a planet orbiting two suns at the same time, like Tatooine from the Star Wars saga.

In the video presentation, experts explain that “the Kepler mission has made an important discovery. The first planet orbiting two suns”.

“At 200 light years away [from Earth], planet Kepler 16-b orbits two suns,” they add.

The small star orbits the larger one (both smaller than our sun), and when her sister gets covered, the brightness in the planet is dimmed to what would be the power of the late evening on Earth.

Kepler 16-B is a gaseous planet of the size of Saturn and nearly a billion years younger than our solar system. Every 239 days, it makes a turn around the greatest. It iscovered by smaller one every 49 days.

While the globe could not sustain life due to its composition, NASA experts do not dismiss being able to find rock planets orbiting around such systems, giving support to one of the dreams of science fiction.

It is available in France. Apple wille be denounced by anti-Semitism.

¿Jewish or not Jewish?, is the name of the new application for Apple iPhones who classified according to whether or not celebrities artists are. In France, it generated controversy The communications company is acussed of violating the Criminal Code.

The application, developed by a British engineer Johann Lévy, can be used on phones from Apple for the cost of $ 1.08, classifying people according to whether they are Jewish mother, father or converts.

The organization SOS Racisme, said that they will denounce the controversial creator of the application and ask the U.S. mobile phone factory, which validates the applications before putting up for sale, to take it out of the market. They may also take legal action against the company Apple.

The International League against Racism and Antisemitiso (Lycra) argues that the application violates Article 226-19 of the French Criminal Code. That article prohibits creating or maintaining computer printout where people are classified according to their religious choice. In case of breach, the law provides a maximum penalty of five years in prison and a fine of EUR 300 000.

Levy, the creator of the controversial application claimed to be Jewish and said: “The goal is to provide the Jews a sense of pride when they see a businessman or celebrity are also Jews.”"The data already on the internet and I have collected myself,” he argued.

A new planet called HD85512b was discovered from the Atacama Desert with a powerful telescope and experts believe could harbor life.

The planet is located about 36 light years from Earth, has between one and ten times the mass of it, reaches temperatures between 35 and 50º and is in the “habitable zone” strip in which the experts placed those planets that may have liquid water and therefore life.

From now on, this celestial body will be watched carefully trying to determine if its atmosphere has oxygen.

With this telescope called Harps, located in La Silla town, astronomers have been able to locate at least 49 exoplanets ie those found outside our solar system.

They have also been estimated that at least 40% of stars like our Sun possess at least a planet smaller than Saturn, which is appropriate to find life beyond this size the chances are nil.

U.S. researchers were able to make some cats immune to the virus that causes AIDS, after a modification in their genome that makes them glow in the dark. Discovery that could help prevent the disease in cats and that would advance research in humans. The study was conducted by inserting genes from monkeys that block the virus in eggs cats. The modified cells could be recognized by the green color caused by inserting genes from jellyfish.

The results showed that cats were resistant to the virus FIV after the experiment causes AIDS in these animals. Dr. Poeschla of the Mayo Clinic in Rochester, who led the study said: “This gives an unprecedented ability to study the effects of protective genes to an animal vulnerable to AIDS.”

He explained: “Humans, cats, and to some extent chimpanzees are the only mammals that develop a naturally occurring virus that causes AIDS.”

Just as the human immunodeficiency virus, or HIV, it does in people, the VIF works by killing cells that fight infections.

In both humans and cats, responsible for combating viruses are protein restriction factors. HIV and FIV, leaving helpless override these proteins the immune system.

However, it was shown that some versions of this factor in the monkey are intact and are able to confront the virus.

“This technology can be applied to a wide range of species for which there are many clear benefits and potential applications,” said Dr. Laurence Tiley, of Cambridge University said in a statement. ”It will be interesting to see how you get this capability in cats and how communities are adopted in HIV research and neurobiology, and what other research opportunities offered. A representative primate animal model would be a great new tool for studying the pathogenesis of HIV, “he said.

Poeschia team plans to go further: “If you can show that you can confer protection to these animals, give us much information about the protection in humans.”

An unmanned U.S. rocket took off heading to the moon

United States, September 11, 2011

From Cape Canaveral in Florida reported that “An unmanned U.S. rocket blasted off on Saturday from the Air Force Station to carry two robotic probes to the moon to discover what is inside”.

As was reported by Reuters “the engine of 37.8 meters, took off from the coast at 13:08 GMT, arching over the Atlantic Ocean as it walked into the orbit”.

The Delta 2 rocket launch took place two days later than was planned because of the strong winds at the launch area and because they had to conduct a technical review of the rocket after the fuel tank was damaged after the failed launch on Thursday.

The twin satellites on board were directed to a point in space 1.5 million kilometers to balance out the gravity of the Sun and Earth.

From there, the satellites of the Interior and Recovery Laboratory of NASA’s Gravity (GRAIL) will approach slowly and extended to the moon, coming back between December 31 and January 1.

GRAIL twin probes are designed to precisely map the moon’s gravity so scientists could find out what lies beneath the lunar crust and if the core is solid, liquid, or a combination of both.

Combined with high-resolution images, current analysis of rock and soil samples taken by the Apollo missions from 1969 – 1972 and computer models, maps of gravity could provide the missing key to the mystery of how was formed and evolved the natural satellite of the Earth.

The ships are connected by radio waves, can detect changes in the strength of lunar gravity as small as one micron, ie, the width of a red blood cell.

Researchers at the University of Bristol, UK, reported that after a high-precision analysis on some of the oldest rock samples from Earth provides clear evidence that the world accessible supplies of precious metals are the result of meteorite bombardment that took place 200 million years after the formation of Earth. This research was published in Nature.

When the Earth was formed, cast iron sank to the center forming the core. This phenomenon has carried the vast majority of our planet’s precious metals like gold and platinum. In fact, there are enough precious metals in the Earth’s core to cover the entire planet’s surface with a layer of four meters thick.

Dr. Matthias Willbold and Professor Tim Elliott of Bristol Isotope Group of Earth Sciences School revealed that they analyzed Greenland rocks formed almost four billion years, collected by Professor Stephen Moorbath, University of Oxford. These ancient rocks provide a unique window into the composition of our planet soon after the formation of the nucleus, but before the bombardment of meteorites.

Meteor impact at the time, shake the mantle of the Earth by giant convection processes. A goal for future work is to study the duration of this process. Subsequently, the geological processes formed the continents and concentrates of precious metals (and tungsten) in deposits of minerals that are mined today.

“Our work shows that most of the precious metals, key to our economies and many industrial processes, came to our planet by a fortunate coincidence, when the Earth was hit by the asteroid material,” experts said.

A huge X class solar flare, the strongest of its kind, took place in the final hours of yesterday and goes straight to the Earth, traveling at 5 million kilometers per hour.

NASA warned about the phenomenon, ensuring that the solar plasma could seriously affect communications on Earth, since it would influence the magnetic field.

Traveling at this speed, the flame would reach the Earth tomorrow and it is feared that the GPS signals, radio communications and energy networks are seriously at risk.

The Solar and Heliospheric Observatory (SOHO) detected the large flare X-2.1 yesterday detailing the phenomenon peaked after eighth minutes of its origin. These ejections are classified into different categories: C, the lowest intensity, M mid-level and X the most powerful.

This reaction of the Sun is not isolated, since it is the second this week. The first was of medium intensity and the plasma was not released to our planet. If it reached the Earth’s magnetic field, it would not have a significant impact, according to experts.

The Sun has just awakened from a sleep cycle; therefore these storms will be constantly, in fact, it is expected about 1,700 of varying intensity this year.

In 2006 took place the highest recorded so far, X-6.9 class, but the plasma was not released to the planet.

Biologists discover why men have longer ring finger than women

United States, September 6, 2011
________________________________________________________

One study conducted by U.S. biologists from the University of Florida has found the reason why men have their ring finger longer than women.

The key is the exposure of the fetus to male and female hormones during pregnancy, which implies a sort of “genetic signature” for the rest of life. This means that the proportions are determined by the balance of sex hormones (androgen and estrogen) during early embryonic development.

This feature of human development can reveal the relationship between the sizes of the fingers with the amount of sperm in men, which means the level of fertility in each individual.

It is also possible to know the sexual orientation, musical ability, aggressiveness as well as the sporting prowess. Also, it is a source of information for health problems such as autism, depression, heart attacks and breast cancer.

Biologist Martin Cohn, who participated in the research, told the journal Proceedings of the National Academy of Sciences (PNAS), which published the discovery that “the proportions of the fingers are a signature for the life of our hormonal environment early.”

He added, “In addition to understanding the foundations of one of the strangest differences between the sexes, it is exciting to think that our fingers can tell us something about the signals that we are exposed for a short period of our life in the womb. There is increasing evidence that several adult diseases are of fetal origin. With the new data, we found that prenatal fingers reflect the activity of androgens and estrogens. “

Facebook renews and adds video calls in joining with Skype

Today’s popular social network ”Facebook” announced the integration of video calls with a number of changes in the designof the website.

Under the “stunning announcement” in the words of Mark Zuckerberg, Facebook introduced the video call function in conjunction with Skype. This company became part of Microsoft,recently.

This service will be available progressively in the next four weeks.For use, it will be need to install a plugin, which is only enabled for Windows and Mac at the moment.

Facebook has 750 million users this way, the summary of the 15th million using Skype. Unlike Hangout, the system offered by Google + video calls, Facebook only allow the individual video calls between two users and not allow multiple conference.

When asked about the functions of this new addition to Mark Zuckerberg said that his company is “Right now is one to one to one communication with multiple functions have the new chat groups.”

There would also be a redesign of the site that would allowmultiple conversations in chat while Facebook had a better view of the contacts.

A bacteria is created to produce vaccine against tuberculosis

Deborah Michelini — Mon, 05 Sep 2011 17:46:58 +0000

September 5, 2011

A modified bacterium, a relative of that causes tuberculosis (TB), has the potential to protect against infectious disease, say U.S. scientists.

As expressed by scientists Albert Einstein College of Medicine in New York, although the study is in its early stages, the finding could lead to a new vaccine against the disease.

The only shot that currently exists against tuberculosis-Bacillus Calmette-Guerin or BCG, is not very effective.
This has shown to have highly variable between 0 and 80% in different parts of the world.

TB is caused by Mycobacterium tuberculosis, kills between 2 and 3 million people each year worldwide.
In recent years the disease problem has been worsened by the emergence of a strain highly resistant to available drugs.

New research published in Nature Medicine, analyzed a group of genes called ESX-3, which are variants that are found in all types of mycobacteria, including M. tuberculosis, and that help the organisms to evade the immune system.
M. tuberculosis can not survive without their esx-3 genes but one of his relatives, llamadaMycobacterium smegmatis, can.
In experiments with infected mice, the researchers removed the genes of the ESX-3 M. smegmatis and injected a dose that would have been lethal genes, in animals.
The results showed that in mice infected with the bacterium M.tuberculosis those who received no vaccine died within 54 days on average.

Those who were vaccinated with BCG lived about 65 days. But the mice immunized with Ikeplus survived 135 days.
However, in animals that survived longer than 200 days, scientists did not detect any trace of the lethal bacterium.
“Consistently we better protect the mice with BCG Ikeplus” explains Professor William Jacobs, who led the study.

The researcher cautioned, however, only 20% of the mice achieved long-term survival, so that the vaccine still needs to be perfected.
As stated by a spokesman for the TB Alert “These are interesting experiments but it is too early to tell what impact the development of a new safe and effective vaccine.”

Nuclear power plant for the Moon, Mars and other planets

U.S. researchers are developing the first nuclear power plant for the production of electricity on the bases of the Moon, Mars and other planets.

James E. Werner, project manager, reported to National Meeting & Exposition of the American Chemical Society (ACS), that “This innovative fission technology is very different from current nuclear power stations onshore, spread over huge areas of land and have large structures, such as cooling towers. This new technology of fission, the reactor itself may be approximately 30 inches wide by 60 high, about the size of a carryon. In addition, there are no cooling towers. A system of nuclear fission energy is a compact, reliable and secure as it can be critical to establish national platforms or habitats on other planets. This technology can be applied on the Moon, on Mars, where NASA needs a continuous power generating point.”

The experts attempt to “build a demonstration unit of this technology in 2012. It is a cooperative project between NASA and the Department of Energy (DOE)”.

Sunlight more fuel were the pillars that generated electricity in past space missions. According to Werner, “The biggest difference between solar power reactors and nuclear power is that nuclear reactors can generate power in any environment. Nuclear fission technology is not dependent on sunlight, which is capable of producing large amounts of energy constant at night or in hostile environments like the Moon or Mars”.

“A fission power system on the moon could generate about the same amount of energy needed to supply eight houses on Earth. Furthermore, this power system could work in a variety of locations such as craters, canyons and caves.The main point is that nuclear power has the ability to provide power anywhere in our solar system and the technology is developed, affordable and safe.While the physics is the same, the low-power control of the reactor and the material used for the reflection of neutrons are completely different.”

Once this technology is fully developed and validated, can be an option more affordable and versatile to provide energy in the long-term space exploration.

Small ‘diamond planet’ is discovered in our galaxy

________________________________________________________

An international team of scientists announced that a new planet was discovered, composed of carbon and high density in the Milky Way i.e. in our own galaxy.

The scientists hypothesize that “it is the densest planet ever discovered” and that “appears to be smaller than Jupiter but has more mass.”

As it was reported in the U.S. magazine Science, the planet lies in the constellation Serpents to only four thousand light years from Earth, which, in astronomical terms, is not that far.

This planet has particular physical characteristics as its composition is primarily carbon and its density is extremely high, which are also diamonds attributes.

Matthew Bailes, a researcher at the Center for Astrophysics in Melbourne, Australia, explained that “There is sufficient evidence to affirm that the planet is 18 times the density of water. That means it can not be made up of gases such as hydrogen or helium, as most of the stars. Rather it should be made of heavier elements like carbon and oxygen, hence its crystalline nature, like diamonds.”

The planet revolves around a star that also has high density, and together they form a binary structure called by astronomers ‘pulsar’, which in less specialized terms may be explained as a small solar system formed by only one star and one planet that share a high-density magnetic field and whose orbital speed is extremely fast.”

The planet is five times larger than Earth and might have previously been a star, but for the moment has no name.

Apple would be making a new version of the iPhone based on the familiar iPhone 4 with an internal storage capacity of 8 GB.

This cell would have a very low value, compared with the current version. This would be possible for the costs the company would save in some components. The new price would be 200 American dollars.

The big fight in the market for smart phones that is occurring worldwide would leave the iPhone in a unique position. The prices of so-called smart phone range from $ 600 onwards. These prices make many companies subsidize operating costs for these phones are more accessible to its customers.

Many users of such phones are expecting with good eyes this possible version of the iPhone 4 8GB, and the other companies must be very clever to compete against it.

Jorge Odon is an Argentine mechanic and inventor who already has several patents, but this new invention, tested by experts, helps both mother and unborn baby.

Everything started with a bet on a friend. He assured that could get a cork from inside an empty bottle with a little plastic bag. The trick was well done and thus he won the bet.

Jorge while asleep had an idea about the trick to ease childbirth. So he presented his new ‘idea’ and was successfully tested in 11 births. Right now, the research is maintained by the Department of Gynecology and Obstetrics Cemic, with the support of the Department of Reproductive Health World Health Organization (WHO).

Dr. Hugo Krupitzi, who participates in the research, said “It is a device designed to facilitate delivery in the so called prolonged second stage, when the woman on the maximum dilation is bidding, but the delivery does not occur.”

Dr. Angel Fiorillo, head of the Department of Gynecology and Obstetrics Cemic added that “The advantage is that a device is inexpensive and easy to implement.” “It can be used in places where there are no ways to solve this situation, as in Africa, where you can not do a Caesarean section or forceps use.”

Other benefits of the device are to reduce the risk of prenatal infections, such as mother-child transmission of HIV, and risk of postpartum hemorrhage.

Solar storms may become more damaging to aircraft and spacecraft

Researchers at the Reading University, England, reported that “Within a few decades, solar storms can become more damaging to aircraft and spacecraft.”

The research was published in Geophysical Research Letters, and it predicted that “once the Sun moves into a period of low solar activity, more dangerous wave of radiation will reach the Earth.”

Experts stated that “the sun is currently in a period of great activity. This phase began in the 1920s and lasted throughout the space age.”

According Professor Mike Lockwood, physics at the Reading University, “All the evidence suggests that the sun will soon leave a large solar maximum, which lasted from before the beginning of the space age.”

In a large solar maximum, the peaks of 11-year solar cycle are larger and the average number of flares and associated events such as coronal mass ejections are greatest.”

On the other hand, in a solar minimum there are almost no sunspots for several decades. The last time this happened was during the Maunder Minimum, between 1650 and 1700.”

“The increase in radiation is a particular problem for the aviation and communications technologies that did not exist the last time the solar cycle finished his maximum”, experts said.

NASA scientists believe they found saltwater in Mars according some photographs taken from the Newton crater near to the Ecuador of the red planet.

The images from the program “Mars Reconnaissance Orbiter” (MRO) show some lines in the surface and according to experts they would be saltwater flows that appear in spring and summer and disappear in the winter of the neighbor planet.

They said it is not fresh water because it would be frozen due to the low temperatures of the zone. At the contrary, the saltwater stayed liquid in these conditions.

However, the scientists confessed that these evidences are not enough to be a hundred per cent sure that these lines are saltwater flows. Nevertheless they are very optimistic.

According a group of investigators the Paracetamol is one of the analgesics more widely adapted in the world that can increase the memory.

They considered that it acts over the key cells that control memory.

The British has an average of 106 Paracetamol pills per year generally used for low the fever or calm the pain.

Scientists believe that its analgesic properties came from the capacity of reduce the number of chemical products in the body called prostaglandins.

These are released as an answer of an illness or injury and it is believed that sensitized the nerve ending.

Experts believed that paracetamol tablets have an enzyme called ciclooxigenasa-2 that stop the production of prostaglandins that caused the pain and show that paracetamol causes the liberation of serotonin on the brain.

They also believe that it activates a brain zone involved in the learning, the memory and the resolutions of problems called hippocampus.

Hundreds of spectators gathered near the lane to welcome Atlantis, which slided through a clear moon light to complete a 13-day-cargo-mission to the International Space Station.

The new project for space shuttles is the Constellation, but it has been put on hold by President Barack Obama due to its costs.

July 2, 2011

Javier Fornes, an Argentine who defines himself as an “inventor”, created the prototype of a device that allows bling people to detect objects which are 3 meters away.

M24Digital did a follow up on this Telemeter which, through sound, is able to make the person aware of objects which are 3 meters away, and even tell about their shape.

Fornes explained that “the device was created to capture dangerous objects on the middle distance, beyond the pole [used by blind people when walking]. It can tell you whether a column is square or round”.

“In the long term there is possibility of transferring auditory cortex to the visual,” which makes it “likely for blind people to see real images, but not as we know them. The brain can form images from the visual cortex”.

The asteroid called MD 2011 approached at a cosmic distance that almost “kisses” the earth yesterday.

The huge rock passed within 7.600 miles of our planet at 18:14 GMT.

In the video, people can follow its journey as the images provide a fascinating insight into how the asteroid travels through the universe. It shows the asteroid’s close encounter with Earth at a speed much higher.

The Earth is directly in the flight path of the asteroid. And fly to the South Pole, traveling over Antarctica and then to the tip of South America before continuing its journey through the universe.

MD 2011 was potentially dangerous because of its size and would have done a terrific bang if it hit our atmosphere, although it would not have reached the ground.

A house size asteroid will pass only at 17,700 miles from Earth, which means an orbit 23 times closer than the Moon.

The asteroid, called 2011 MD, has a diameter of about 8 to 18 meters, but this doesn’t represent any danger to our planet, in fact if it gets into the atmosphere will become a fireball and would be completely destroyed.

The passage of the asteroid is so close that its orbit will be modified by the gravity of Earth. The same will approach to the area where the communications satellites are placed, but the possibility of a collision is minimal, experts say.

The closest approach of the rock will be held on Monday at 13.26 UTC, on the southern Atlantic Ocean, off the coast of Antarctica. Consequently, in some areas of the southern hemisphere, the asteroid can be seen with an amateur telescope.

As reported by the Wall Street Journal, Google will be investigated by the United States to determine if it breaks the antitrust law in that country.

The Federal Trade Commission (FTC) holds “the most serious antitrust complaint so far” against the search engine, used by two thirds of Internet users in that country.

Until today, Google only had been examined by some of its acquisitions (like YouTube), but this time the charge is more serious because there is evidence that controls more than half of U.S. traffic.

British police said Tuesday that “arrested a 19 year old boy on suspicion of masterminding the international group of hackers called LulzSec.”

He was arrested during a raid organized jointly by Scotland Yard and the U.S. FBI.

This group recognized “have been behind several security breaches to the websites of several organizations, including the Organized Crime Agency of the United Kingdom, the United States Senate and the CIA, as well as companies Nintendo and Sony.”

Also LulzSec reported its assault on government computer systems in the UK saying that “managed to extract all information from the UK census of 2011 and by the time saved the data to give them the correct format and can be distributed across from ThePirateBay.”

The group highlighted its alliance with Anonymous (another group of hackers) to conduct coordinated attacks against any government, agency or corporation in the world to try to stifle freedom and progress.

LulzSec this morning attacked a security agency, the British government (SOCA).

LulzSec once acknowledged responsibility for the attacks said they used the portal Pastebin, which became one of the main roads to ensure that the attacks managed data across the population census of 2011 UK.

Scientist Natalia Avseenko, 36, swam without any artificial material (that includes clothing) between belugas in Russia to study its relationship with humans.

The specialist tried to approach and domesticate the animals near Murmansk Oblast in the northwestern zone of the Eurasian country.

The belugas, dolphins premium species, flee to artificial materials, for which Natalia had to undress for a swim in the water, which was at 1.5 degrees below zero.

Avseenko worked with Nilma and Matrena, who live in the Utrish Dophinarium. For this, he used yoga techniques that allowed him to be 10 minutes under water.

Primitive black hole discovered in a distant galaxy

_______________________________________________________

American astronomers reported “the first black hole discovered at an early stage of its development in a distant galaxy, a phenomenon that is very difficult to find because they are hidden behind dust and the gas that cause their host galaxies.”

This finding was published in the journal ‘Nature’, and according to the article, “the scientists used a technique called ‘stacking’, which consists of overlapping photos with different foci and approaches.

Trhough it they can detect signals incredibly weak issued by the central black holes in distant galaxies, about 13 billion light years from Earth.

Astronomers select about 250 galaxies (detected by the Hubble Space Telescope) that were postulated as good candidates to host a black hole at its epicenter.

University of Yale cosmologist Priyamvada Natarajan said that “the discovery of the distant black holes were also used to verify that this phenomenon is growing and evolving with their host galaxies, a trend that experts were able to see in the nearby universe and now corroborate the farthest.”

Kevin Schawinski, another expert at the university said, “This discovery tells us that there is a symbiotic relationship between black holes and galaxies, and this union has existed since the dawn of time.”

Scientists at the National Solar Observatory (NSO) and the Air Force Research Laboratoy (AFRL) reported that “The sun is up for the start of a new solar cycle with little activity and compared with that experienced in 1645 when there was a period of solar inactivity for 70 years who is known as the ‘Little Ice Age’. ”

After studying the Sun they detected a decrease in sunspot area and lower activity near the poles that determined a decrease in its activity and even hibernation for the next solar cycle, ie in the next 11 years.

NASA had been warned about this situation earlier this year when one of its scientific teams detected solar inactivity in the last three years.

Scientist Richard Fisher said that “the solar cycle, which usually lasts about 11 years, has its natural periods of low activity, however, this solar minimum is’ historically low and is lasting more than usual.

The main symptom of this slowdown in solar activity was detected in the absence of magnetic charge at its poles.

If the poles can not be loaded, the Sun will increasingly losing power during the cycle, and may even get to stop their activity almost completely.

The aircraft ‘Solar Impulse’ abandons its second international flight

The aircraft ‘Solar Impulse’, this Saturday, had to travel from Brussels to Paris, and after more than 24 hours, due to the high winds and rain in the Belgian capital it had to abandon its second international flight as the aircraft moves through solar energy.

Just after a few minutes of flight, participants stated that “they were experiencing difficulties that occur one after another”.

In its first international trip, Brussels – Payerne (Switzerland), it took 13 hours to complete the journey.

The prototype, which has a wingspan of 63.4 meters, similar to an Airbus 340, with a weight similar to a car – 1,600 kilos, “technology allows you to fly without fossil fuel and only solar energy reserves, acquired to over 12,000 photovoltaic cells, which move four engines of a power of ten horses each”.

Its first flight was conducted over 26 continuous hours, and remained in the air with the sun’s energy that was absorbed during the day, beating the record for flight duration of appliances nature.

In addition it surpassed the absolute altitude, 8,700 meters, and 11 hours and 53 minutes won the height up to 8,261 meters.

An Argentine satellite was launched today from the Vandenberg base, located in California, USA, through a Delta II rocket of 40 meters height.

While it will be on orbit at 650 kilometers above the Earth, the satellite called SAC-D / Aquarius will monitor the salinity of the ocean to collect data on climate change, thanks to some powerful sensors.

This ambitious project, now come true, was built by the National Commission on Space Activities (CONAE) and Invap, a privately held company and the state of the Rio Negro Province, in cooperation with the National Aeronautics and Space Administration of United States (NASA).

Argentina President Cristina Fernandez de Kirchner accompanied the release from the Government House and said, “It is the effort of our universities, is the effort of CONICET, the CONAE effort and is the effort of all Argentines”.

In addition, the president made a comparison with the 2001 crisis, saying “10 years ago we threw stones, now we are launching rockets and satellites.”

NASA’s Voyager spacecraft came to 14,500 million kilometers from Earth and are broadcasting news from the unexplored reaches of the solar system.

According to mission scientists they have just received very significant evidence.

They find out that the Sun’s magnetic field becomes bubbles in the heliopause.

The Sun’s magnetic field extends all the way to the edge of the solar system. Because the Sun rotates, its magnetic field becomes twisted and wrinkled, a bit like a ballerina skirt. Far, far away from the Sun, where the Voyagers are now, the folds of the skirt pile.

When a magnetic field is severely bent in this case, interesting things can happen. Magnetic force lines intersect and connect magnetic reconnection is the same energy process underlying solar flares. The folds of the skirt tend to reorganize, sometimes explosively, magnetic bubbles in foam.

World Day of IPv6, The sites change from the current IPv4 system to IPv6

June 8, 2011
_______________________________________________________

The strongest companies in the network like Google, Yahoo, Microsoft, Bing and Facebook are testing for one day the change of their sites from the current IPv4 system to IPv6.

The new Internet protocol IPv6 is more extensive than the present and guarantees that “the Net will continue to increase” and it celebrates on Wednesday June 8 the World Day IPv6.

For 24 hours, some of the world’s most important pages, like Google, Facebook and Yahoo will offer its content in the new protocol on a trial.

The aim is to encourage industry organizations, Internet service providers, manufacturers in hardware, operating system developers and companies operating in Internet-to prepare for IPv6 services in order to ensure the successful transition as IPv4 addresses are depleted.

Communication between different network elements and our own computer, telephone or ‘tablet’ uses a protocol called Internet Protocol (IP), whether for browsing, email or download a file. Practically since the Internet has a commercial use, the version of this protocol is the number 4 (IPv4). When IPv4 was designed almost as an experiment, it wasn’t thought that could have so much commercial success.

In this sense, one of the “fathers” of the Internet, Vint Cerf, recalled in January that the world would run out of IP addresses “within weeks” and acknowledged that this is due to a failure since the creation, as when IPv4 was designed in 1977, unaware that the “experiment end.”

In February, the Internet Corporation for Assigned Names and Numbers (ICANN) reported that it had delivered the last block of IPv4 addresses.

In this regard, Cerf also predicted that after the exhaustion of IPv4 addresses, there are some devices that only will understand IPv6, so it can be interactions problems with the old system.

Scientists found an explanation for the Bermuda’s Triangle

June 4, 2011

Apparently U.S. scientists found an explanation for shipwrecks and plane crashes at the site.

Much has been spoken about paranormal activities, sea monsters, UFOs and other explanations for unexplained phenomena. Those had been explanations among the mystery of disappearance of ships and planes in the Bermuda Triangle.

According to scientists in the area there are not aliens or anything unusual, just a lot of methane hydrates that come to the surface and cause instability.

The experts said that these banks of gas come from volcanic sites where bubbles are generated in an enormous way and grow geometrically while gaining altitude. For this reason the ship are captured by the balloon gas and immediately loses buoyancy and sinks.

The mystery began after a group of planes with 14 men aboard disappeared in December 1945. One of the pilots went on to say in the black box “we are entering white water, nothing seems to be right”.

However, in recent years, researchers have argued that the number of ships and aircraft lost in the area was statistically irrelevant, when compared with other parts of the ocean.

June 3, 2011.- A group of hackers called LulzSec claimed the attack on Thursday, which affected the personal information of more than one million customers of Sony.

The group said through a statement that “From a single operation, we can access to everything” and “Why do you put such faith in a company that allows itself to become open to these simple attacks?” they ask, saying that the data also wasn’t encrypted.

They also claim “have entered into a database that includes unencrypted passwords, names, addresses and dates of birth of users.”

Representatives of Sony confirmed that “they are investigating the statement made by the hackers on the theft of a million users’ passwords. A group of hackers calling itself LulzSec said jeopardized the personal information, including passwords, email addresses, phone numbers, addresses, dates of birth, and Sony all data related to their accounts.”
