A new study contradicts prevailing theories about the origin of water and life on Earth

These analysts suggest that the origin of terrestrial water and life can come from carbonated chondrites and comets.

Scientists have been long convinced that comets, or other more primitive meteorites called carbonaceous chondrites (stony meteorites-non-metal-with chondrules, submillimeter spheres formed by different minerals) were the origins of the elements volatiles from the Earth, including hydrogen, nitrogen and carbon, and possibly organic elements. Understanding the origins of these volatile elements is crucial in determining the origins of the present water and life on our planet. New research, led by Conel Alexander, Carnegie Institute, focuses on the frozen water was distributed throughout the solar system, but probably not in the materials initially joined to form the Earth.

The evidence of this ice is now present in objects such as comets and carbonaceous chondrites aquifers. The findings of this group of researchers contradict prevailing theories about the origins similar two body types and suggests that meteorites, asteroids and primitive, are more likely to direct sources of ground water, rather than comets. His work has been published on July 12 in Science Express.

Looking at the proportion of hydrogen in the heavy isotope deuterium in water ice (H2O), scientists can get an idea of ​​the relative distance from the Sun to which objects containing water were formed. The objects that formed farther from the Sun should generally have a higher proportion of deuterium in the ice that formed those close and those that formed in similar regions should have similar isotopic compositions of hydrogen. Therefore, when comparing the deuterium content in water of carbonaceous chondrites with deuterium content of comets, it is possible to identify whether similar regions formed in the solar system.

It has been suggested that comets and carbonaceous chondrites formed beyond the orbit of Jupiter, perhaps even within the limits of the Solar System, and then moved inland, over time even coming to Earth, along with his loading of volatiles and organic material. If this theory were true, then the ice found in comets and the remains of ice preserved in carbonaceous chondrites in the form of hydrated silicates such as clays, may have similar isotopic compositions.

Alexander's team includes scientists from Carnegie Nitler Larry, Marilyn Fogel, and Roxane Bowden, as well as Kieren Howard, Natural History Museum of London, Christopher Herd, University of Alberta. Samples of 85 carbonitas carbonaceous, and were able to show that they are not formed in the same regions of the solar system comets, as they have much less deuterium content. If this is substantiated by the study contradict the two dominant models of the formation of our solar system.

These analysts suggest that carbonate chondrites formed in the asteroid belt between the orbits of Mars and Jupiter. What is more, they suggest that most of the volatile elements terrestrial arrived from a variety of chondrites, not from the kites.

"Our results show important new constraints on the origin of volatile elements in the inner solar system, including Earth. And they have essential implications for current models of formation and orbital evolution of planets and minor bodies in our solar system," concludes Conel Alexander

Solar Storm On Thursday | 13.03.2012

Our planet will undergo a bombardment of electromagnetic particles that should affect our technologies ...

Attention storm. From Thursday, the largest solar flare in five years will lead to Earth particle bombardment electromagnetic might disrupt satellite communications and electrical distribution networks, announced Wednesday the U.S. authorities.

This eruption of solar plasma occurred Tuesday night and its effects should not be felt on our planet before Thursday morning around 13h French time, to last until Friday, according to forecasts by the National Oceanic and Atmospheric (NOAA).

Increase in solar flares

This solar storm, charged particles that hit the Earth at a rate of 6.44 million km / h, can potentially affect the distribution of electricity, satellite communications, GPS, astronauts on the International Space Station (ISS) and compel airlines to change their routes to avoid the polar regions.

A spokesman for NASA told AFP that the agency took no specific action because "we do not believe that the ISS crew is in danger." "Increasing the number of solar flares - the last occurred on January 23 - is normal in terms of business cycles of eleven years the sun, which for this period is expected to peak in 2013, " NASA explained.

One of the most powerful since 2006

Such intensification of solar flares is more common as the sun completes one cycle of activity minimum to start a much longer active. The solar storm is probably "one of the most powerful since December 2006," according to Joseph Kunches, space weather expert at NOAA.

Besides the risk of disrupting communications satellites now highly dependent, the latter probably solar storm will create auroras in Central Asia on Thursday evening, promises Joseph Kunches. These experts point out that the Earth is well protected from these solar storms by its magnetic field.

What is Solar Tsunami?

A 60,000-mile-high wave of super-hot plasma blazing across the sun’s surface at 560,000 mph? Yep.
“Now we know. Solar tsunamis are real,” said John Gurman of the Solar Physics Lab at the Goddard Space Flight Center, in a press release Tuesday.

NASA’s Solar Terrestrial Relations Observatory has confirmed that the crazy circular bursts on the surface of the sun, rising higher than the Earth is wide, aren’t just optical illusions.

STEREO consists of two spacecraft pointing at the sun, one ahead of Earth in its orbit and one behind, that acquire stereoscopic images of the sun to give a sort of three-dimensional view, similar to the way our two eyes do.

Though these solar tsunamis, technically known as fast-mode magnetohydrodynamical waves, were first seen by the SOHO mission more than a decade ago, the single spacecraft couldn’t determine if the wave was real or the shadow of a coronal mass ejection. But in February the STEREO twins were perfectly poised to catch the eruption of a sunspot that spawned a wave, seen in the movie above.

“It was definitely a wave,” George Mason University scientist Spiros Patsourakos, lead author of a paper on the solar tsunamis in August in The Astrophysical Research Journal Letters, said in a press release. “Not a wave of water,” he adds, “but a giant wave of hot plasma and magnetism.”

solar_tsunami_orangeThe spacecraft have also spotted waves crashing into other solar structures.

“We’ve seen the waves reflected by coronal holes. And there is a wonderful movie (at right) of a solar prominence oscillating after it gets hit by a wave (near the top of the image),” co-author Angelos Vourdilas of the Naval Research Lab in Washington, D.C., said in a press release. “We call it a dancing prominence.”

Watching the waves interact with other things can reveal new information about the sun’s atmosphere, and help forecast when a coronal mass ejection or radiation storm will impact Earth.

Strawberry Crab Information

Ever see a crab with a shell like strawberries? It must not ever do you? Now this rare two tailed crabs found in Taiwan.

Both are true crabs have been found since June 2009 earlier in the Kenting National Park, Taiwan. At that time, Ho and his team are doing a study on the impact on marine life shipwreck. According to Ho, the southern coast of Kenting National Park is known as an area rich in diverse marine creatures.

Ho takes long enough to determine that the species had found a new species of crab. After analyzing approximately 10 000 species of crabs, then Ho is sure to announce that the invention is at least a new species of crab. Thus the quoted statement from Discovery, Wednesday (06/01/2010).

When you first see it, everyone will be impressed with the crab shells. If in general the red crab shell looks smooth, not so with this new crab species. On a bright red shell scattered small spots of white colored, strawberry-like fruit. Appearances like this then make it known crab crab strawberries.

Ho and his team from National Taiwan Ocean University mentions strawberry crab species generally live in waters of Hawaii, Polynesia and Mauritius. But the crabs are found a little different because it has a shape like a clam shell and the width approximately 2.5 cm.

Battery that generating energy when you shake it

A Japanese electronics company sourced a vibration generator that can replace the standard battery.

Brother Industries, better known as the typewriter products, claimed this tool can replace the role of AA or AAA batteries for sjeumlah usage.

At an event in Tokyo, this tool switch Brothers shows a remote control (remote control), a button to turn on the lights and LED flashlight sbeuah.

The mechanism works similarly to a bicycle dynamo, only difference with whipped several times a direct electrical power generated.

"Vibration Energy Battery Cells we create electric power with the introduction of a spring, magnet, and the condenser which produces electricity. All this is in in the battery," a spokesman told BBC News Brother.

"Because the power produced by only a little then this tool is designed for use on devices like TV remote and LED devices, which only require low power and electrical power do not eat constantly."
Shake energy

The idea behind this technology is the need to replace the use of batteries that contain toxins that harm the environment.

So far two new AA size model products generate voltages elbih at 3.2 V or lower, just enough to fill the electrical power tools such as remote control.

Yet according to Carl Telford, an analyst at consulting firm Strategic Business Insights, says this battery is a potential breakthrough.

"That was great because if you need AA batteries for electric power is shaken; eg for remote control," he added on BBC News.

"The size is too small, dense, and can be directly used on the electricity resources that we know. Brother says this tool can generate electric power at low frequencies, skeitar 4-8Hz - is impressive."

"If you walk with this tool in the bag it will produce vibrations with a frequency of about 2Hz. You do have to shuffle the tool is on loud, but can lah."

While other companies are also pursuing a target to find the source of a new battery without charge standard.

U.S. Companies Inc. TenXsys. Kinetic Energy is currently developing technology for these devices, including scavenging for military equipment.

While the UK mobile company Orange has recently revealed its newest product Power Wellies, are made with the cooperation with renewable energy experts GotWind.

Teleportation can be achieved 10 Year Again

According to a survey involving 1,500 British citizens, approximately 31 percent of them believe that if the teleportation technology will be realized in the near future.

Teleportation itself is a technology that can move the object / person from one place to another through space and time. This technology has the same sense with the theory of quantum leap.

Amazingly, through a survey conducted computer company Cisco, many British citizens who believe in this theory. In fact, they are more skeptical of the technology available today. Many of those who believe if a new video conferencing technology will be booming in a much longer period, although this technology is already in general use today.

In fact, the public predictions about the future of technology such as broadband is also quite surprising and terlau does not seem accurate. Of the total respondents, approximately 65 percent of them believe that if 100 Mbps broadband connection may not be implemented within four to six years in the future. Even ultra high speed broadband connections will be implemented in several cities in the UK until the end of this year.

This report provides insight into the expectations of society towards technology as well as how well people perform filtering information into environmental innovation.

"25 years ago there were approximately 1000 hosts on the Internet, now there are more than 1.7 billion Internet users worldwide, and human networks to create change in the way we live our lives, businesses and jobs," said Cisco CEO and VP of Ireland and England.

Although there has been a big leap in technology in recent years but many of the general public who just are not aware of new technologies.
Smart Fridge example. Many of respondents who believe that if such new technology will be implemented in the year 2015. But it turns out, Electrolux now has a refrigerator model that is able to send picture messages (MMS).

The survey is part of Cisco's report, entitled 'Connected Conversations'.

CEO Phil Smith also commented on the future of technology and stating that if 2010 was a year of considerable importance. "2010 is the year of change in Green technology, fast broadband, business intelligence, digital economy, community regeneration, innovation, infrastructure, public sector efficiency. This is more than just words. They are important elements that will shape, not just the British economy, but the whole world, "he said.

"Technology has become a big part to play in the UK in preparing for the future, and we are far more ambitious to create technology that can provide something for us," he added.

This is the Aircraft Design Future of NASA

Not only taking care of the problem space, the United States space agency, NASA also contributed to develop future aircraft design in NASA Aeronautic Fundamental program, April 2010.

Through research for 18 months, NASA visualize the future of passenger aircraft. This new aircraft design will be applied 20-25 years from now. There are some fresh design ideas - although the first sight looks old. Instead of adopting the form of a plane in science fiction, this new aircraft design was drastically different from the existing form of aircraft.

However, if we look carefully, there are significant differences - a new breakthrough in the framework of the aircraft and the use of technology will make the plane more peaceful future, not noisy, clean, and efficient fuel. Also emphasizes the comfort of passengers.

By looking at the design of NASA, you can also see the shape of ultramodern with ceramic or composite fibers, carbon tubes, fiber optic cable, aircraft skin layers that can improve themselves, hybrid electric engines, folding wings, fuselage double, and a virtual window.

"Standing in front of the future, you probably can not distinguish with conventional aircraft. However, developed the revolutionary," said project scientist of NASA Fundamental Aeronautics Program, Richard Wahls, such as pages loaded NASA, Wednesday, May 19, 2010. "The amazing thing is on the technology, not just wrap the plane," he said.

In October 2008 then, NASA has called on industry and academia to imagine the concept of sophisticated aircraft in 2030's, which can anticipate the needs of commercial air transportation, but efficient in using fuel, is also environmentally friendly.

NASA did not say with certainty whether this future aircraft will be used for domestic flights or international flights with more distance.

Four teams joined in this program, namely:

1. GE Aviation team put the concept of a future aircraft that could carry 20 passengers. This aircraft can carry passengers from one location to another - are expected to reduce congestion in the metropolis.
This plane forms an oval, with a leveling feature air flow across the surface. The aircraft had fuel power plants that sophisticated. Aircraft engine was noisy, could take off in quick time and did not require much time to raise the aircraft.


2. Aircraft D 8 'double bubble' by the Massachusetts Institute of Technology (MIT) can carry 180 people - combining two of the fuselage to install three turbofan jet engine in its tail up position. Komponan important plane is the use of lightweight materials and bypass ratio turbofan engine with an ultra.

D8 design team to do the same job with the Boeing 737-800.



3. Boeing Company to develop subsonic Ultra Green Aircraft Research (SUGAR), dual-engine aircraft with hybrid propulsion technology. Having such tube fuselage and wings which help the plane climbed to the top. Compared with existing aircraft, SUGAR wing is longer, but can be folded when parked at the airport.


4. Northrop Grumman team's biggest need for the future foresee is the availability of the aircraft carrying 120 passengers, with smaller sizes and only require short runways.

The team called this plane as Silent Efficient Commercial Low Emissions Transport (SELECT). SELECT revolution is on its performance rather than on display.

Anthropologists have uncovered ancient fossil footprints in Kenya

Anthropologists have uncovered ancient fossil footprints in Kenya dating back 1.5 million years, the oldest evidence yet that our ancestors walked like present-day humans, a study showed Thursday.

The footprints were discovered in two sedimentary layers near Ileret in northern Kenya and revealed an essentially modern human-like foot anatomy.

The impressions came from the Homo ergaster, or early Homo erectus, the first hominid whose longer legs and shorter arms corresponded to the body proportions of the modern Homo sapiens, the study's authors said.

The footprints provided information on the soft tissue form and structure that are not usually available in fossilized bones, explained Matthew Bennett of Bournemouth University in Britain, the lead author of the study published in the journal Science.

Bennett scanned and digitized the footprint to make sure that comparisons with modern human and other fossil hominid footprints were objective.

The upper sediment layer contained three footprint trails: two trails of two prints each, a trail of seven prints and several isolated prints.

The other sediment layer, five meters (16 feet) deeper, preserved a trail of two prints and a smaller isolated print that the authors said probably was that of a child.

In all specimens, the big toe was parallel to the other toes, unlike apes, whose big toes are separated to help grasping tree branches. The Ileret footprints also show a pronounced arch and short toes that are human-like and are usually associated with the ability to walk on two feet.

Several Homo ergaster and Homo erectus fossils dating from the same era as the Ileret prints have been found in Tanzania, Ethiopia, Kenya and South Africa.

In 1978, British archeologist and anthropologist Mary Leakey discovered footprints in Laetoli, Tanzania that dated back 3.6 million years. But those prints were attributed to a less advanced creature, the Australopithecus afarensis, that showed a shallower arch and a more ape-like separated big toe.
