You know, one gram of DNA can store files up to 2.2 million gigabits of data information or about 468 thousand DVD, which can last up to more than six hundred years without a rewrite.

A new technology that might replace today's hard disk storage technology. During this storage technologies such as flash drives that we use everyday, has a weight of more than one gram. While one gram of human DNA that exist in the body, can store data of millions of times more, impressive is not it?

The results of a recent study presented at the American Astronomical Society Conference in California on Monday (07/01/2013), revealed that the number of Earth-sized planets in the Milky Way reached 17 billion, is on one of the six stars.

Some planet orbits its star at a distance that is relatively close, closer than Mercury's orbit distance. Further studies need to be conducted to determine the number of Earth-sized planet orbiting at a distance further away, are in the habitable zone.

The mission is the search for extrasolar planets by the Kepler telescope. Research shows that 17 percent of the planet candidates Kepler found measuring 0.8 to 1.25 times the size of Earth and orbits in 85 days or less.

The percentage of super-Earth planets dengqn 1.25 times the size of Earth's orbit about 150 times larger today as much as 25 percent. The same percentage also owned a mini planet Neptune with 2-4 times the size of Earth and orbits with a time of about 250 days.

Meanwhile, the larger planet less frequently. Only three per cent of the candidates belonging to the class planet Neptune, 4-6 times Earth's size. Only 5 percent were classified as a gas giant, 6-22 times the size of Earth and orbits its star with a period of about 400 days or less.

Francois Fressin, researchers from the Harvard Smithsonian Center for Astrophysics, who presented the results, said the planet circling all types of stars. He also said there are many factors that support life on Earth that has not been found on other planets.

"There are a number of factors supporting 20-30 life on Earth as we know that may not be found on other planets. Example, it may be very rare to see Earth-like planet that is only partially covered with water," said Fressin as quoted by Discovery, Monday.

In his presentation, Fressin also revealed that there were 461 candidate planets found by the Kepler again. In total, there are 2740 candidate planets found. Research on planet candidates were expected to reveal the existence of a second Earth.

LONDON, KOMPAS.com - a giant cliff with a depth of 250 meters was found at the bottom of the Red Sea. The cliff is found by the mission of the MHS Enterprise owned by the British Navy.

The cliffs are found when the mission of HMS Enterprise 3D mapping the Red Sea region to the west of the Suez Canal, Egypt. The Ministry of Defence announced this discovery on Tuesday (02/26/2013).

The cliffs can be found with the help of sound waves. The sound waves are sent to the ocean floor and then let bounce. The longer period waves bouncing, the more the seabed being mapped.

The data obtained by observation is then converted into a 3D map. Finally, the discovery of a class Grand Canyon's cliffs.

Derek Rae, mission controllers Enterprise, told Discovery on Tuesday, said, "The cliffs may be formed from an ancient river that breaks the rock before it turns into the Red Sea region thousands of years ago."

It is possible, cliffs also has a younger feature, a feature that is still suffering formation.

Enterprise will still be in the Middle East this year. Its mission has remained the same, map the seafloor. Brother mission, HMS Echo, after 19 months of the mission, managed to find a variety of wrecks in various waters of the world.

LONDON, KOMPAS.com - British scientists find life gap hot water (hydrothermal) deepest in the world. This discovery utilizing robotic remote-controlled study (ROV) equipped with a camera with high definition images.

This gap is known three years ago in the Cayman Trough, a giant trench between two tectonic plates. One part of that hydrothermal vents at depths Beebe named 4968 meters below sea level.

On the BBC website, on Thursday (21/02/2013), is described, expedition funded by the Natural Environment Research Council using British research vessel James Cook. Lead researcher Jon Copley of the National Oceanography Center said the ROV observations demonstrate the amazing view.

There is life in the gaps "spout" water temperatures over 400 degrees Celsius along the seabed water temperature 4 degrees celsius. Extreme difference is exploited marine animals to live.

Investigators found a white ghost shrimp in the rocks. Hydrothermal vents is an interesting site for research scientists since first discovered in the 1970s. At least, 200 points hydrothermal vents have been known, especially in the South Atlantic Ocean and Aquatic

BRUSSELS, KOMPAS.com - Stone space found in Antarctica. Size is sufficiently large meteorite. Weighing up to 18 kg.

The team of scientists from Belgium and Japan found a meteorite while exploring the highland areas in eastern Antarctica. Initial identification shows that it is kind of chondrite meteorites, the most common type of meteorite found.

"This is the largest meteorite found in Antarctica east in 25 years," said Vinciane Debaille, a geologist from the University of Brussels.

"It's something very special. When you find a meteorite on Earth, is actually much larger sizes while still in space," he added, as quoted by LiveScience, Thursday (28/02/2013).

Every year, many scientists find meteorites in Antarctica. Environmental snowy, cold, and dry ikllim help preserve the space rock.

Debaille own expedition managed to find a meteorite 425 in 40 days. Total weight of meteorites collected up to 75 kg. According Debaille, the team may find Martian meteorites and meteorite fragments asteroid Vesta.

It has long been suspected that one of the causes of the extinction of the dinosaurs is an asteroid hit. The incident occurred during the Tertiary and Creatcous known as the KT event.

Now, geologists find new evidence that what is alleged is true. Geologists analyze the impact crater 180 km wide near the town of Chicxulub, Mexico. A 10 km asteroid impacts that releases energy as much as 100 trillion tons of TNT, billions of times the Hiroshima and Nagasaki bombs.

The results of the analysis revealed that the collision that formed the Chicxulub crater and the KT event only difference 33,000 years. These results were obtained with high precision radioactive dating techniques, see the proportion of radioactive material in the crater impact.

The fact revealed by this study to update the results of previous research which states that the difference with the KT impact event that formed the Chicxulub is between 300,000 and 180,000 years old.

"We show that the impact and mass extinction occurred coincident in time so that one can be demonstrated with existing dating techniques," said Paul Renne, an expert geokronologi and Berkeley Geochronology Center director in California.

Although the impact and mass extinctions occurred within huddle, asteroid impact can not be said to be the sole cause of extinction. Climate change is happening millions of years in the future also contribute herding animals on the brink of extinction.

"The phenomenon that happened before makes a global ecosystem becomes more sensitive to triggers that are relatively small," Renne said as quoted by LiveScience, Thursday (02/07/2013) ago. This research was published in the journal Science, Friday (02/08/2013).

Today the world is being led to the nanotechnology revolution in which up to 2020 will be remarkable acceleration occurs in the application of nanotechnology in the industrialized world.

It is common knowledge that the developed countries of the world, such as USA, Japan, Australia, Canada and European countries, as well as some Asian countries, such as Singapore, China, and Korea amid Actively develop a new branch of the popular technology called Nanotechnology.

As the name implies, nanotechnology is a technology on the scale of nanometers, or billionths of a meter. With nanotechnology, Indonesia's natural resource wealth can be given added value in order to win the global competition. By creating substance to measuring one-billionth of a meter (nanometers), the nature and function of these substances can be changed as desired.
Nanotechnology, technology-based nano-sized materials management or one-billionth of a meter, is a leap in technology to transform the material world become much more valuable than ever.
While the nanomaterial is a major cornerstone in the development chain of nanotechnology products. Not to mention the micro-electronics technology based on silicon (1 micrometer = 0.001 millimeter) that dominate all aspects of human life can be controlled, the world has entered a new era called nanotechnology. It is an engineering material in order nanocrystal (1 nanometer = 0.000001 millimeters)
Any material as long as can be made in the form of a nanocrystal will produce stunning nature and does not even exist in nature. It is estimated by 2010, industrial products to any scale will use nanotechnology material engineered. The rapid development will change the face of technology in general because nanotechnology penetrated all areas of science. the term "nano". The term comes from the word nanos (Greek) which means one billion.

So 1 nanometer (nm) is equal to 12 048 meters. Nanotechnology is a technology that involves atoms and molecules with a size smaller than 1,000 nanometers. That means the size can be up to 100,000 times smaller than the diameter of a human hair. Superkecil, supermungil. But that does not mean the benefits too small. This tiny it has tremendous potential in providing answers and solving complex problems in the world.

Something that can precisely micro-sized macro impact. From the standpoint of size up and down like that, nanotechnology is important in the world of engineering as mankind strives to integrate a function or work in the nano-scale size lebih.Teknologi able to make the drug in nanogram size.

Only in times of a generation, now the Bamboo Curtain country has been transformed from an agrarian country to country with the largest industrial and commercial power is very strong. China's economy is now 20 times larger than 20 years ago and are now beginning to approach the strength of the U.S. economy which is the country with the strongest economy today.

But other things that also need to be a concern as well as tremendous economic power rapidly is the fact that the Chinese government is currently also active in the middle of building their military strength.

Ten years ago, the budget allocated for the Chinese People's Liberation Army (People's Liberation Army) is about 20 billion dollars. And now, some analysts expect the military budget has almost reached 160 billion dollars.

Chinese President Hu Jin Tao said that currently the Chinese People's Liberation Army historic center of the mission of the new century 21. Of the task of maintaining the sovereignty of China into a global military force in order to become a true superpower.

In some cases the presence of the Chinese army and can indeed go hand in hand with the United States military as when China joined the anti-piracy patrols in the sea of Somalia.

But some analysts worry that if one day the two forces met in a state with the aim of mutual beseberangan. Then there would be very risky because the two countries share the best military technology today.

U.S. government officials are not just worrying magnitude of China's military budget, but also the fact that China's military now has the capability of military technology that is almost equivalent to the United States.

 
For example, during the American found that F-22 fighter and the F-35 is the fighter of the fifth generation fighter aircraft which only the United States alone (both aircraft types is the aircraft that has the ability of anti tracked radar, capable machines and systems the ultimate flight control, and has a dedicated network computer systems). However, in 2011, when the U.S. defense secretary Robert Gates visited China, Chinese President Hu Jintao greeted by featuring performances flying J-20 fighter plane over the city of Cheng Du (This is just one type of anti-radar aircraft that are not confidential, how with the other?).

United States plans to introduce and launch the spacecraft's new military. Spacecraft and secret military smaller and unmanned. Spacecraft is part of the future U.S. air forces.

AFP on Tuesday (12/11/2012), reported that the spacecraft X-37B weighs five tons and a length of 8.9 meters. Spacecraft can carry a variety of materials from space to Earth as the shuttle program that has been retired. This aircraft was designed to be longer in space, ie 270 days.

X-37B aircraft last return to Earth in June last year of a pilot in space for 469 days. United Launch Alliance, a joint venture between U.S. aviation giant Boeing and Lockheed Martin, have agreed to the presence of the X-37B at Cape Canaveral, Florida, after a successful trial results following a launch into space separated two months ago.

This confirms the joint venture parties, global satellite positioning system (GPS) was successfully placed in orbit as expected on 4 October.

Patrick Air Force bases reported to signal alert when the launch schedule between the hours of 10:45 to 17:15 local time on Tuesday. This was reportedly due to a fuel leak in one of the rooms of fuel forcing the plane investigation.

So far the U.S. authorities did not give more information about the shuttle program recently. Information from the U.S. Air Force said the launch of this "experimental test program to demonstrate the technology reliable, can be reused, a program of unmanned space test for the U.S. Air Force.

Aircraft-secret X-37B made the speculation in the media that the spacecraft is designed to destroy enemy satellites state.

In 2007, China became the first country after the U.S. and the former Soviet Union managed to shoot its own satellites. An experiment by the Washington regarded as the increasing power of China's ambitions in space.

Project X-37B launched the U.S. Space Agency, NASA in 1999 before it adopted the Defense Advanced Research Projects Agency, which is designed with a new technology for the U.S. military.
