Alien Spaceships are Coming to Earth, November 2011


Planet Earth and it's natural satelite - the Moon


NASA confirmed that three alien spaceships are on track to arrive in Earth’s atmosphere.

Three giant alien spaceships are heading for Earth! Scientists predict they will arrive in November of  2011.


Three giant ships with aliens are traveling to Earth. We will meet them soon - in November, estimated scientists from the Research Center of SETI (Search for Extraterrestrial Intelligence). Do not rush to enjoy your dream to see a UFO, because the intentions of the aliens are not clear. 


Aliens who recently passed by Jupiter, are detected by the system HAARP, based in Alaska. HAARP was designed to study the phenomenon of northern lights.
“Three giant spaceships are heading toward Earth. The largest one of them is 200 miles wide. Two others are slightly smaller. At present, the objects are just moving past Jupiter.  Judging by their speed, they should be on Earth by the fall of  2011” said John Malley, the lead extraterrestrial expert at SETI. 


Scientists are adamant that these are alien ships. In November 2011 - when they reach Mars' orbit - they will be close enough to be seen with optical telescope. The U.S. government is aware of the "event". 


Alien (not a real picture)

Recently controversial site "Wikileaks" revealed many classified documents, proving that senior NASA and U.S. figures are informed about the journey of the three extraterrestrial ships. They are even making plans to battle the spaceships. They have been concealing information from the U.S. public for decades. According to "Wikileaks" there is sufficient evidence that the UFO invasion has begun - something that SETI has predicted.

The three spaceships will mark the official beginning of the alien invasion.


A Chinese official had obtained over than 1,000 secret NASA photographs depicting not only human footprints, but even a human carcass on the surface of the Moon. Some of the bones in the carcass were missing, the official said. The human corpse must have been dropped on the Moon from an alien spaceship, whereas the extraterrestrials kept some tissue samples for research.


Dr. Ken Johnson said that U.S. astronauts had found and photographed ancient ruins by an unnatural artificial origin, on the Moon.
US astronauts had seen large unknown mechanisms on the Moon.


Beginning in August of 2011 the U.N. will begin preparing citizens of the world for the attack of the three spaceships – which are believed to come from Planet Zeeba.




Earth and Moon - part of the Solar System

These news really sound like a screenplay for some fantastic sci-fi movie. But the scientist are very serious, they say their statements are true.

Alies - a dream for some, a fear for another, a fiction for others.


Looks like in just a mounth we all will see if there are aliens. 
If they are having good or bad intentions.
So... we will wait, until November comes.

Internet Addiction - More Powerful Than Drugs

Internet Addiction

Young people are spending much more time infront of the computer screen, than outside.
Younsters prefer to stay at home and browse the Internet. They don't anymore like to go out and take a walk in the park or play some sport.

Is Internet becoming more powerful addiction than the drugs?
Look at the answers in the article - they're based on statistical researches and young people's opinion.

The Effects of Internet Addiction

From 2002 until today the number of young people, using drug and tobacco products is reducing, the expense of increasing addiction to the Internet and electronic games, a survey of Brussels Free University. 

For the past nine years, declining by six per cent of young people who smoke every day - from 18,7 percent to 12,7 percent. In 2002, eight out of every 100 youths said they smoked marijuana at least once a week and recently gave a similar response to 4,9 per cent of respondents. When ecstasy users also experience a change - from 5,3% nine years ago to 2,7 percent last year. 

According to sociologist Damien Fravres, these data can be explained by increased parental control over young people who have come out less at night. So basically they are spending more time in their rooms, sitting at the computer. The survey reported that while in 2002 only seven percent of young people said they spend at least four hours daily in front of the computer, the latest data show an increase of nearly double those responses - 13%. 

The survey was conducted among 12 000 young people aged between 12 and 20 years.

Are We Being Held in Chains by the Internet?

Yes, I think that computers and Internet are very useful. But we should not overdo anything.

It's true that most of the youths are spending they time in Internet social network, than going outside with friends and talk face to face.

Particles Travel Faster Than Light

Physicists reported that sub-atomic particles called neutrinos can travel faster than light, a finding that - if verified - would blast a hole in Einstein's theory of relativity.


Physicists have found that tiny particles called neutrinos are making a 454-mile (730-kilometer) underground trip faster than they should — more quickly, in fact, than light could do. If the results are confirmed, they could throw much of modern physics into upheaval.


In experiments conducted between the European Centre for Nuclear Research (CERN) in Switzerland and a laboratory in Italy, the tiny particles were clocked at 300,006 kilometres per second, about six km/sec faster that the speed of light, the researchers said.


"This result comes as a complete surprise" said physicist Antonio Ereditato, spokesman for the experiment, known as OPERA. "We wanted to measure the speed of neutrinos, but we didn't expect to find anything special."


Results from the CERN laboratory in Switzerland seem to break this cardinal rule of physics, calling into question one of the most trusted laws discovered by Albert Einstein.

Scientists spent nearly six months "checking, testing, controlling and rechecking everything" before making an announcement.


Researchers involved in the experiments were cautious in describing its implications, and called on physicists around the world to scrutinise their data, to be made available online overnight.


But the findings, they said, could potentially reshape our understanding of the physical world.


"If this measurement is confirmed, it might change our view of physics" said CERN research director Sergio Bertolucci, a view echoed by several independent physicist contacted by AFP.


In the experiments, scientists blasted a beam producing billions upon billions of neutrinos from CERN, which straddles the French-Swiss border near Geneva, to the Gran Sasso Laboratory 730 kilometres away in Italy.


Neutrinos are electrically neutral particles so small that only recently were they found to have mass.


"The neutrinos arrived 60 nanoseconds earlier that the 2.3 milliseconds taken by light" Ereditato told AFP.


Under Albert Einstein's theory of special relativity, however, a physical object cannot travel faster than the speed of light in a vacuum.


Newton's theory of gravity, still explains the movement of planets well enough to send missions into space, even if Einstein's theories proved that it was not quitecorrect.


Theoretical physicists are sure to begin searching for new explanations to account for the unsuspected quickness of neutrinos.


It could be that "the particles have found a shortcut in another dimension" besides the four - three in space, plus time - we know about.


"Or it could simply mean that the speed of light is not the speed limit we thought it was."

Dinosaur Feathers Found in Amber

The dinosaur feathers encased in amber

CNN - Dinosaur feathers discovered in 80-million-year-old amber provide new clues about dinosaurs.

Paleontologists made this discovery of feather specimens near Grassy Lake in southwestern Alberta, Canada, and described the results in the journal Science.

Researchers don't know which feathers were actually from birds that flew and which might have been from theropod dinosaurs, but the filament structures resembles those seen in other non-avian fossils.

There appear to be two types in the sample: those resembling the feathers of modern birds, and "protofeathers" which are similar to the hair-like structures found in a halo around dinosaur specimens from China in early Cretaceous rock. Those simpler feathers in the amber, which differ from what modern birds have, may have came from small, meat-eating dinosaurs.

"Sort of finding a dinosaur trapped in the amber itself, it’s the best we can do" said Ryan McKellar, a paleontology graduate student of the University of Alberta and lead author of the study.

Although the feather fragments themselves are tiny - ranging from only 2 to 8 millimeters in length - they are preserved in 3D in extraordinary detail, scientists say.

Even some of the pigment remains, so we know what color feathers may have covered these prehistoric creatures. The dinosaur-looking ones display a pale to dark brown color, while the bird-like feathers have a wide range of appearances: There are white downy feathers, as well as flattened, veined feathers of black, brown, and lots of shades in between.

The dinosaur-looking feathers resemble mammal hair-fur and would be useful for things like insulation, and perhaps camouflage and display. The bird-like feathers are even more specifically formed: Some fragments have structural adaptations for flight, and others show characteristics of being able to pick up water, so they could carry water back to their nests or dive better.

How do feather fragments get so well preserved?

About 80 million years ago, these feathers likely blew into some tree resin and, over time, it hardened into an intermediate stage called copal, which then turned to amber. The resin hardens as its volatile component dissipates, and what's left behind is similar to plastic in structure.

The amber used in jewelry today is usually about 17 million to 40 million years old; more than 65 million years old is too brittle for decorative purposes, meaning there probably aren't dinosaur feathers in your mother's amber necklace.

But insects do often get trapped in amber; in fact, McKellar and colleagues found a feather fragment trapped in a spider web in one of the pieces of amber. That's right, there were spiders making spider webs 80 million years ago.

Fat Cells for Broken Hearts



A company is testing whether stem cells from fat could help prevent long-term damage after a heart attack.

Too much fat around the waist may be bad for your health, but the stem cells it contains might one day save your life. Starting this month, a new European trial aims to determine whether stem cells harvested from a person's own fat, delivered shortly after a heart attack, could prevent some of the cardiac muscle damage that results from blocked arteries.

During a heart attack, blood vessels that deliver blood to the heart muscle are blocked, and the lack of oxygen slowly kills the tissue. San Diego-based Cytoryi Therapeutics has developed a treatment that aims to prevent much of that muscle damage before it starts. It works by injecting a concentrated slurry of stem cells and other regenerative cells isolated from the patient's body directly into the heart's main artery within 24 hours after an attack. "Time is muscle. The quicker you get in, the better," says Christopher Calhoun, Cytori's chief executive officer. "You can't do anything about dead tissue, but tissue that's bruised and damaged—that's revitalizable. If you can get new blood flow in there, that tissue comes back to life."

Adult stem cells, which exist in small populations throughout the body, can differentiate to form specific tissue types and are responsible for repairing injuries and replacing dying cells. The prospect of using them to heal damaged heart muscle has tantalized biomedical researchers for more than two decades. If the stem cells come from a patient's own body, there is no risk of rejection. A number of clinical trials in recent years have focused on using stem cells collected from bone marrow, since this potent population can differentiate into both cardiac muscle cells and blood vessel cells, among other types. But marrow stem cells are difficult to collect and somewhat scarce; they must be isolated and then grown in culture before they're injected back into an injured heart. The process can take weeks.

Cytori has created a portable machine that, in less than an hour, can reduce a sample of fat "about the size of a can of Coke," Calhoun says, to less than a teaspoon of concentrated slurry that Cytori believes contains its most vital elements: stem cells, smooth muscle cells, cells that line blood vessels, and a number of other regenerative cells that can promote growth healing.

Cytori began a large-scale trial this month and hopes to test the procedure on 360 patients. The company aims to start large-scale clinical trials on heart attack patients in the United States by 2014 and on patients with chronic heart failure even earlier than that.

But it's still early. Clinical trials of stem cells derived from bone marrow have shown mixed results in treating heart disease, and it's unclear whether fat-derived cells will fare better. "If it works, it would be wonderful to have a ready-made source of autologous stem cells," says Richard Schatz, research director of cardiovascular interventions at Scripps Health in San Diego, one of the inventors of the coronary stent. But he and others note that it will take many more trials to determine how effective Cytori's methods are compared with treatments based on marrow stem cells.
