Lasers drag tractor beams from sci-fi to sci-possible

A Week After The Invention of a Worlds First Anti laser,a device that absorbs, rather than emits,a beam of light.Scientists Have Successfully Demonstrated The Possibility of Tractor Beam In Future.
Tractor Beam is a Term Familiar To Those Who Are Fans of Science Fiction Movies Like Star Trek And Star War and Even In Austin Powers.
All Those Catchy intresting Concepts of Science Fiction Are more Likely To be Real soon Like Warp Effect,Anti laser ,Antimatter,Teleportation And Now the Star Trek Iconic Concept of Gravitational Beaming Of Objects "Tractor Beam"
Its Not A Thing To us ,Scientists are carrying out on this Things From Decaes And They Are Working on  Every Single of possibility of Turning of Our Science Fiction Things Into Reality .Tractor Beam is Very Famous For its Usage in Star Trek the starship Enterprise often dragged objects towards it with its glowing tractor beam.
Now There Is Every Possibility of Having This In Reality .But It May be Take a Decade To get into Play.

So What is A Tractor Beam And How It Drags The objects

A tractor beam is a device with the ability to attract one object to another from a distance. Since the 1990's, technology and research has labored to make it a reality, mostly at microscopic level. Less commonly, a similar beam that repels is called a pressor beam or repulsor beam. Gravity impulse and gravity propulsion beams are areas of research from fringe physics that coincide with the concepts of tractor and repulsor beams.

When light falls on an opaque object, the surface reflects most of the photons back in the direction they came from. What's less obvious is that these bouncing photons push back on the object, causing it to move away from the light source. If the object is very small, this push can be significant. But this is the exact opposite of the suction-like behaviour of tractor beams in science fiction.

Now Jun Chen of Fudan University in Shanghai, China, and colleagues, have shown that it is possible to create exotic beams that would pull rather than push on an object. For tiny particles with dimensions of a thousandth of a millimetre or so, this would result in the particle being drawn back towards the beam.

These Latest Advacnements Proves That The Future is Of "Lasers" And Likely To Live In The World Of Science Fiction  Movies.

'Anti-laser' built for first time

Two Scientists of Yale university Have Created The World's First Anti Laser,a device that absorbs, rather than emits,a beam of light unlike The conventional Laser Which Emits The coherent Beam of Light In only One Direction.The concept was first published in the July 26, 2010, issue of Physical Review Letters, by a team at Yale University led by theorist A. Douglas Stone.From Then Attempts Are progessed in A Way to Create Antilaser.

Antilaser Works In Exact Opposite of Laser it absorbs and light and forces them to move until their energy vanishes.In a laser, energy is pumped into a medium — which can be a solid, liquid or gas — between two mirrors, stimulating the emission of photons that are coherent, or of the same frequency and phase. The photons reflect back and forth between the mirrors, resulting in amplification of the light.

An anti-laser uses mirrors, too, but the other components are the reverse of a laser. The medium that provides amplification is replaced with one that provides absorption, and the outgoing light beam is replaced with an incoming one.

The device focuses two lasers beams of a specific frequency into a specially designed optical cavity made from silicon, which traps the incoming beams of light and forces them to bounce around until all their energy is dissipated.

In a paper published in the journal Science they demonstrated that the anti-laser could adsorb 99.4 per cent of incoming light, for a specific wavelength.

This Turns to be a Significant Invention which would be a major advantage for Computing Because it is built using silicon.This Could be A Path for Future Generation of computing Called optical Computing ,We can Build Super computers using light instead of High level present computing replacing electrons .It can also be used In Radiology for treating of Cancer to concentrate  to a small region within normally opaque human tissue.
Anti-lasers could be used to modulate the intensity of that light, or to convert light signals into electrical form for on-chip processing, the researchers say.Anti Lasers can Alos Be used In Defence  .
Well Apart From these It could become a part of Future of  Science Fiction movies,The Hero May counter Attack The Bad Guys with Anitlaser.

Lasers have also become a fascination of many television shows and movies.We Have Seen Movies Of James Bond,Batman that Have dealt with lasers.Even an Episode In Bigbang theory ,a group of guys who work in physics at a university in California, make a machine to shoot a laser and reflect it off the moon. Its Time For Antilaser To Take over the screen.
Now batman Has got Another Weapon in his sack of Weapons.It would Be Exciting for movie buffs To watch this on screen

Quantum Entanglement Could Stretch Across Time--Wired Science

In the weird world of quantum physics, two linked particles can share a single fate, even when they’re miles apart.
Now, two physicists have mathematically described how this spooky effect, called entanglement, could also bind particles across time.
If their proposal can be tested, it could help process information in quantum computers and test physicists’ basic understanding of the universe.
“You can send your quantum state into the future without traversing the middle time,” said quantum physicist S. Jay Olson of Australia’s University of Queensland, lead author of the new study.
In ordinary entanglement, two particles (usually electrons or photons) are so intimately bound that they share one quantum state — spin, momentum and a host of other variables — between them. One particle always “knows” what the other is doing. Make a measurement on one member of an entangled pair, and the other changes immediately.
Physicists have figured out how to use entanglement to encrypt messages in uncrackable codes and build ultrafast computers. Entanglement can also help transmit encyclopedias’ worth of information from one place to another using only a few atoms, a protocol called quantum teleportation.
In a new paper posted on the physics preprint website arXiv.org, Olson and Queensland colleague Timothy Ralph perform the math to show how these same tricks can send quantum messages not only from place to place, but from the past to the future.

The equations involved defy simple mathematical explanation, but are intuitive: If it’s impossible to describe one particle without including the other, this logically extends to time as well as space.
“If you use our timelike entanglement, you find that [a quantum message] moves in time, while skipping over the intermediate points,” Olson said. “There really is no difference mathematically. Whatever you can do with ordinary entanglement, you should be able to do with timelike entanglement.”
Olson explained them with a Star Trek analogy. In one episode, “beam me up” teleportation expert Scotty is stranded on a distant planet with limited air supply. To survive, Scotty freezes himself in the transporter, awaiting rescue. When the Enterprise arrives decades later, Scotty steps out of the machine without having aged a day.
“It’s not time travel as you would ordinarily think of it, where it’s like, poof! You’re in the future,” Olson said. “But you get to skip the intervening time.”
According to quantum physicist Ivette Fuentes of the University of Nottingham, who saw Olson and Ralph present the work at a conference, it’s “one of the most interesting results” published in the last year.
“It stimulated our imaginations,” said Fuentes. “We know entanglement is a resource and we can do very interesting things with it, like quantum teleportation and quantum cryptography. We might be able to exploit this new entanglement to do interesting things.”
One such interesting thing could involve storing information in black holes, said physicist Jorma Louko, also of the University of Nottingham.
“They show that you can use the vacuum, that no-particle state, to store a lot of information in just a couple of atoms, and recover that info from other atoms later on,” Louko said. “The details of that have not been worked out, but I can foresee that the ideas that these authors use could be adapted to the black hole context.”
Entanglement in time could also be used to investigate as-yet-untested fundamentals of particle physics. In the 1970s, physicist Bill Unruh predicted that, if a spaceship accelerates through the empty space of a vacuum, particles should appear to pop out of the void. Particles carry energy, so they would be, in effect, a warm bath. Wave a thermometer outside, and it would record a positive temperature.
Called the Unruh effect, this is a solid prediction of quantum field theory. It’s never been observed, however, as a spaceship would have to accelerate at as-yet-unrealistic speeds to generate an effect large enough to be testable. But because timelike entanglement also involves particles emerging from vacuums, it could be used to conduct more convenient searches, relying on time rather than space.
Finding the Unruh effect would provide support for quantum field theory. But it might be even more exciting not to see the effect, Olson said.
“It would be more of a shocking result,” Olson said. “If you didn’t see it, something would be very wrong with our understanding.”

Antimatter created, captured for the first time

Scientists working at the CERN announced they have Created And Captured Anti Matter For the First time , which could offer new insights into the universe.
They were able to preserve the antimatter atoms for one-tenth of a second.

Scientists working on the big bang machine in Geneva have done the seemingly impossible: create, capture and release antimatter.

The development could help researchers devise laboratory experiments to learn more about this strange substance, which mostly disappeared from the universe shortly after the Big Bang around 14 billion years ago.

Right from the day when Antimatter was first predicted in 1931 by the British physicist Paul Dirac, who theorized that antimatter is ordinary matter in reverse.It was Huge subject For science fiction movies like Startrek Series and To  Dan Brown 's Angels and Demons .

And now it was No longer a fantasy in science fiction movies as physcits made this possible .I'm a Guy who relates Everything In Life whether its science or sports to Movies,so Whenever i Think of Antimatter The First thing which comes in Mind Is the movie " Angels And Demons" in which a secret society hides an antimatter bomb beneath St Peter’s Basilica in Rome.If you have seen Angels and Demons then you would understand why am i saying .Its Not only a Mystrey Thriller film following symbols but for the First time it Made me to Realise The concept of Antimatter.Movie Presented An Excellent Demonstration of How Antimatter is Created ,what Results May end up if we play with Antimatter.

So What is AntiMatter

Antimatter is ordinary matter in reverse. Atoms normally consist of positively charged nuclei and negatively charged orbiting electrons. Their antimatter counterparts have negatively charged nuclei and positively charged electrons. For example, a positron (the antiparticle of the electron) and an antiproton can form an antihydrogen atom in the same way that an electron and a proton form a normal matter hydrogen atom. Furthermore, mixing matter and antimatter can lead to the annihilation of both in the same way that mixing antiparticles and particles does, thus giving rise to high-energy photons (gamma rays) or other particle–antiparticle pairs.This Energy can Be used for productive purposes rather than Destructive way.
A single pound of antimatter would contain more destructive power than the largest H-bomb.
Previous Experiments

In 2002 scientists at CERN produced antihydrogen atoms in large quantities, but they had an incredibly short lifespan -- just several milliseconds -- because the antihydrogen came into contact with the walls of their containers and the two annihilated each other.

In this latest experiment the lifespan of the antihydrogen atoms was extended by using magnetic fields to trap them and thus prevent them from coming into contact with matter just like vials seen in Angels and Demons but of huge size.

The researchers created 38 antihydrogen atoms and held on to them for about a tenth of a second, which is long enough to study them says Professor Jeffrey Hangst, one of the team of CERN scientists who worked on the program.

Invisibility cloak closer with flexible 'metamaterial'

  

Scientists in the UK have demonstrated a flexible film that represents a big step towards the “invisibility cloak” made famous by Acclaimed Socio-Fantasy series Harrypotter.
Scientists are Close to Relaising the scientific fantasies As we see Regularly in science Fiction movies,the may be close In near future the Flying cars,Warp effects of Star trek,3d Holograms Of Starwars can be Reality.

As cloaks  designed  to shield objects from Tera Hertz and Near Infrared waves have already been designed by phyicsts at St. Andrews Universityin Scottland,they have develpoed the Metamaterial which can create  independent flexible material that could theoretically appear invisible to naked eye ideal for use in a wide range of applications including the Invisibility cloak.It manipulates The Behaviour of Light.But these Materials only affected light of a colour far beyond the human eye’s ability to discern.

 The tiny structures in the newly Created film bond together to create a meta-material which causes objects to become invisible by bending light around them.

The New York Journal of Physics has reported the demonstration and physicists worldwide have declared the approach a giant step forward in light-bending technology. They haven’t, so far, commented on the social implications of an invisibility cloak.

Meta-materials work by blocking and channelling beams of light at a fundamental level, bouncing light waves in prescribed directions in order to achieve a planned result. The laws of optics work in such a way that light can only be manipulated by structures around the same size as the light-waves’ lengths.

Until the recent demonstration, the most striking former demonstrations of invisibility have used light waves with a longer wavelength which the human eye cannot detect. The reason for this is that it is far easier to construct these materials with larger structures.

The shorter light waves that the human eye can discern require nanostructures, which stretch the boundaries of present-day manufacturing techniques to the limit. The author of the paper presented at the demonstration, St Andrew’s University’s Andrea di Falco, said that the most important step in the process was believing that it could be done.

Dr di Falco used a thin polymer film to fabricate a single layer instead of the previously-used brittle silicon and proved that the film had the properties to construct a 3D flexible meta-material. The physicist Ortwin Hess, holder of the Leverhulme Chair in meta-materials, has welcomed the work as ‘a huge step forward in many ways’. He told reporters that it’s not yet an invisibility cloak but it’s the right way forward.

Astronomers Say they have Found oldest Galaxy

Astronomers Believe That They Have Found the oldest thing ever seen in the universe,It's A Galaxy Far away From us,From a lont time ago.

A team Of European Astronomers Have Managed to Calculate the oldest And Farthest Galaxy in the universe after Analysing the hidden small smudge of light in a Photograph by
Hubble Telescope earlier This year.
It was now the Farthest Thing ever know To man which was Estimated to be Formed around 13.7 billion years ago.Scientists say that the light was from the time when The universe was very young,Just 600 million years old.
The Galaxy was temporarly named by a sequence of Letter and digits ,"UDFy-38135539".
The European astronomers calculated the age after 16 hours of observations from a telescope in Chile that looked at light signatures of cooling hydrogen gas.

Earlier this year, astronomers had made a general estimate of 600 to 800 million years after the Big Bang for the most distant fuzzy points of light in the Hubble photograph, which was presented at an astronomy meeting back in January.
The Light coming from The Galaxy might Be from the ages of Early big bang which is carrying some Valuable Information about the formation of universe and stars.ofcourse We are not sure that Galaxy may still be of its Earlier Form ,it may be Transformed into Bigger one or it just collapsed.
This Would be an useful finding for astrnomers to find and answer the various Questions on when The first Stars and Galaxies are formed.

Star Trek Teleportation is likely to be reality -"Beam me up Scotty"

When ever i Watch Star Trek Series and Movies one thing i Fantaise was about the teleportation,moving from one palce to another .
I used To play myself being Captain Spock saying my Brother the iconic Phrase "beam me up scotty",well all that were chidish games.

But they are no longer a Dream.soon this could be close to reality as scientists successfully teleporting objects from one place to another with the help of Energy Rays.
A team of scientists at the australian national university in canberra using tractor,the tractor beams the rays that can move objects .they managed to shift tiny particles up to 59 inches. 

The machine used to create the tractor beam which brought the art of molecular transportation closer
The method involves the shining of a hallow laser beam arouny the object which heats up the air around it ,but the centre of the beam which strikes the particles stays cool resulting in their being drawn towards the beam's warm edges. 
The heated air molecules that are bouncing around strike the surface of the object surface and nudge it back to the cooler centre. Researcher mr.rhode said his team can movie objects 100 times bigger over a distance of almost five feet .the daily mail

DNA test may predict your child's talent-ACTN3 sports gene

 

An increasing number of curious parents are going to subject their children to a DNA test to determine what they will be best at as adults in future.

Already in the developed countries like us and Europe such tests have progressed to determine the child's potential IQ,memory power.

It will help the parents the way they  groom  children.

Even, India has started using to  to ascertain what sport their children will do best in when they grow up.
“Analysis of the ACTN3 gene can be used to predict the kind of muscle fibre the child will develop as he/she grows up. Based on this we can figure out the body’s capacity to adapt to different sports,” says a leading orthopedic surgeon,Mr Naresh Padmanaban in Chennai.

The sample can collect as many as 10,000 cells that enable scientists to isolate up to 40 different genes.

By studying the genetic code, scientists can extract specialized DNA information about a child's IQ, athletic ability, artistic ability, emotional control, focus and other talents and even health and disease related factors.

Doctors use information extracted from what they claim is the "sports Gene" to predict what kind of game the child will be best suited to.

Tablet PC for $ 35

India’s Human Resource Development Minister Kapil Sibal recently revealed the prototype of a $35 touchscreen tablet device,which is India's first ipad like computer with fully Indian technology .
Mr.Kapil sibal launched this prototype on 31st of last month.


Aimed at students, the tablet supports web browsing, video conferencing and word processing, say developers.

Human Resource Development Minister Kapil Sibal said a manufacturer was being sought for the gadget, which was developed by India's top IT colleges.

Earlier cheap laptop plan was came forward by mit(Massachusetts Institute of Technology) to develop a laptop for $100 which eventually droped .


The newly revealed Linux-based $35 device, looks very similar to iPad, and feature 2 GB of memory, a USB port, and built-in Wi-Fi connectivity.

The $35 tablet prototype from India, which was developed by research teams at IIT and the Indian Institute of Science, is expected to go into production by 2011.

Most Advanced Microscope of World

Canadian center for Electron Microscopy has developed a new powerful microscope Titan 80-300 cubed that is the most powerful microscope till now.


According to Gianluigi Botton, Director of Canadian center for Electron Microscopy, says that the power of this microscope can be thought as equivalent to "taking Hubble Telescope and aiming it at atomic level"

"With this microscope we can now easily identify atoms, measure their chemical state and even probe the electrons that bind them together," added  Botton.
John Preston, director of McMaster's Brockhouse Institute for Materials Research, said  scientists will be now  able to understand, alter and improve products' efficiency which help in diagnosis of a disease.
scientists are planning to use the titan to make research on protiens and for drug delievery to identify cancer.

Fei company,a Netherlands Based company which supplies electron microscope tools for manufactures and researchers build this microscope with an estimated cost of $15 million .
