Pranav Mistry’s Sixth Sense Technology.

Sixth sense! you know all about sixth sense very well. Till now you were completely aware of five sense. but now a days as technology is growing up very fast, there is more space at the bottom. New technology is now sixth sense?

 I will say in answer about this is latest new tech for your future is sixth sense. now you are reading this article on your pc or laptop or on your mobile, but after some days, you will read in on any surface. YES, sixth sense means that you can do anything without pc, means you can make any surface ad monitor, keyboard, or mouse. your palm will be used as your photo frame, your table surface can be used as keyboard. with sixth sense you can see video in your news paper! ! !

 Now, we use the projector to project the visual information by using some surface like white curtain or may be walls and the moving objects around us can be used as interfaces. In the meantime, the camera recognizes and feeds the user’s hand gestures and physical objects on the screen using computer-vision based techniques, somewhat like a touchscreen 

So strange ? don't be that. this is all right. And credit goes to Mr. Pranav Mistry . Pranav Mistry has redefined the meaning of this word using visual tracking fiducials, which is going to change the whole dynamics of how the digital world and the real world operate. He is a MIT’s Media Lab PhD student in the Fluid Interfaces Group. The technology says, that we can bridge the gap between the real and virtual world.

And the news is the model based on above theory will be in market soon. I think it's price will be around $350. Ya, that's right! you think it's costly ! but it's beginning.

New Research Explores 'False Memories': you have to know

Did you really lock your door, or is it all in your head? Researchers exploring the 

fascinating phenomenon of false memories have observed subjects who had false 

memories created by watching someone else. Researchers found the subjects were 

much more likely to falsely remember doing an action if they had watched someone else 

do it.

 eaPsychological resrch has shown various ways "false memories" are created, such as through the power of suggestion or through vivid imagination. Now scientists studying imagination have found that people who watched a video of someone else doing a simple action often didn't remember and thought they had done it themselves when asked about it two weeks later.

"This is a completely new type of false memory," says Gerald Echterhoff, a psychology professor at the University of Muenster in Germany and co-author of the paper published in the September issue of the journal Psychological Science.

"This is a false memory from just observing someone," he says.

Psychologist Daniel Schacter of Harvard University in Cambridge, Mass., who has edited a book on false memories, says he hasn't read the new paper, but it "sounds like an extension of earlier work that has shown imagining you'd done something can result in false memories."

"I think it's partly new and partly related to earlier work," Schacter says. "You saw something on TV that you think actually happened. It's another kind of example of what people have talked about as a source memory failure."

Echterhoff says more than 25 percent of participants in the study, as well as in several follow-up experiments, had false memories created by watching someone else. Since the first research on 170 participants was done, findings have been replicated with almost 500 participants, he says.

The paper details three different experiments in which participants read about or actually performed a series of simple actions, such as shaking a bottle or shuffling a deck of cards. Then they watched videos of someone else doing simple actions -- some of which they had done and some they had only seen being done. Two weeks later, they were asked which of as many as 30 actions they had done themselves.
Researchers found the subjects were much more likely to falsely remember doing an action if they had watched someone else do it. Echterhoff says the research controlled for the common situation of thinking you had done something because you do it yourself every day.

Zeiss adapts lenses to video SLR era

Carl Zeiss, a venerable German maker of camera lenses, is showing new ambitions by trying to tap into the market of video SLRs and by expanding into the realm of accessories.

The company has announced two new lenses in its Compact Prime CP.2 line, a second generation of hybrid lenses designed for use either on cinema cameras or on newer SLRs that can shoot video.

The new CP.2 models are a 50mm f2.1 macro with 0.24-meter close-focus distance and a 100mm f2.1 with a 0.7-meter close-focus point. The new products debuted at the IBC Conference for the media and entertainment industry.

The CP.2 models are notable for an adapter ring that makes it possible to fit the lens to a variety of camera bodies--initially those using Canon's EF mount and the PL (positive lock) mount used in filmmaking circles. Now Zeiss has released an adapter that lets the lenses attach to the F mount of Nikon SLRs as well. That helps with photographers or videographers who might have a variety of cameras in use.

In addition, Zeiss "soon" plans to expand to the Micro Four Thirds lens mount used by new Panasonic and Olympus cameras and to the Sony Alpha mount. One point worth mentioning: it's easier to span all these camera body styles because because cinema users rely on manual focus; Zeiss's CP.2 lenses don't have the electronic links necessary for autofocus and other camera communications.

The CP.2 lenses use the same optical formulas as the company's other lenses, but are particularly suited to cinema purposes. For example, all the models except the new 100mm macro lens have the size lens barrel for easier interchangeability when mounted in a camera rig. And they have a higher-precision focusing ring that travels 300 degrees, a silently changing aperture setting, a 14-blade aperture for more pleasing bokeh in out-of-focus areas, and gearing for attachment of follow-focus equipment and other external apparatus.
The CP.2 line isn't cheap, with an average price of $3,900, but the lenses are less expensive than the other cine lenses of Zeiss' Ultra Prime and Master Prime lines.

Zeiss also has expanded beyond its core lens products to accessories. First up are polarizing and ultraviolet filters with diameters of 58mm, 67mm, 72mm, and 82mm. Second is a padded camera strap with quick-release buckles.

Also, earlier this month, Zeiss announced a new member of its more photography-oriented lenses, the Distagon T* 1,4/35 ZE, a 35mm f1.4 lens with a cost of about $1,700. It has a close-focus distance of 0.3 meters (11.8 inches), 11 lens elements, and a weight of 850g (1.9 pounds).(by:stephen Shankland)

LOOKING TO LEAVES FOR SOLAR TECHNOLOGY ???

• A leaf is constantly building new photosynthetic reaction centers to replace those damaged by oxygen and sunlight.

 

• Scientists are experimenting with ways to apply the same principles to building solar energy cells.

 

• This new technology could yield a system that's highly efficient, can self-repair and works well under low light conditions.

Plants may hold the key to better solar technology

A new technique may one day lead to solar cells that bring themselves together like a molecular flash mob and repair damage they sustain during the rough business of turning light into electricity.

The research lays the groundwork for cheap, self-repairing solar cells with an indefinite lifetime, a team reports Sept. 5 in Nature Chemistry.

"It's a man-made version of what nature does," says nanocomposite expert Jaime Grunlan of Texas A&M University in College Station. "This really looks like ground-breaking seminal work; I've never seen anything remotely like it."

The sun's rays can be brutal, even for a leaf that's harvesting them. When photosynthesis is going full blast, a leaf is constantly building new photosynthetic reaction centers to replace those damaged by harsh oxygen species and other destructive molecules generated by intense ultraviolet light.

So rather than trying to make solar cells that are extremely durable, the team decided to take a literal leaf from nature's book and go the route of self-repair, says chemical engineer Michael Strano of MIT, who led the project. He and Stephen Sligar and Colin Wraight of the University of Illinois at Urbana-Champaign, along with other colleagues, designed a system where damaged parts could be easily replaced.

The researchers began with light-harvesting reaction centers from a purple bacterium. Then they added some proteins and lipids for structure, and carbon nanotubes to conduct the resulting electricity.

These ingredients were added to a water-filled dialysis bag -- the kind used to filter the blood of someone whose kidneys don't work -- which has a membrane that only small molecules can pass through. The soupy solution also contained sodium cholate, a surfactant to keep all the ingredients from sticking together.

When the team filtered the surfactant out of the mix, the ingredients self-assembled into a unit, capturing light and generating an electric current.

The spontaneous assembly occurs thanks to the chemical properties of the ingredients and their tendency to combine in the most energetically comfortable positions. The scaffolding protein wraps around the lipid, forming a little disc with the photosynthetic reaction center perched on top.  These discs line up along the carbon nanotube, which has pores that electrons from the reaction center can pass through.

Adding the sodium cholate back into the mix disassembles the complexes. But filtering it out again brings them right back together.

"The idea that it happens reversibly and at will is quite amazing," says Strano. "It approaches what happens in biology -- forming a huge amount of order with the flip of a switch. It's kind of like taking puzzle pieces and throwing them up in the air and them coming down assembled."

The complexes eventually lose power, but they are easily revived, says Strano. The research team disassembled the units and replenished the photosynthetic reaction centers. Four such replacements over the course of a week kept keeping the complexes humming along.

"This is very nice work -- the procedure they've got, the control they have over the system," says biochemist Mike Jones of the University of Bristol in England. "It's simple, it's very nice."

The units can't compete with silicon-based solar cells in use today. But silicon-based solar cells reached their current level of efficiency only after decades of research and development, says Jones. Similar investment in this new technology could yield a system that's highly efficient, can self-repair and works well under low light conditions, he says.

What's more, the main ingredients for these solar cells might one day be easily extracted from plant material, says Strano, perhaps even from garbage biomass. "We could turn waste into an organized product," he says.

GAMMA RAY 'RACE' PROVES EINSTEIN RIGHT AGAIN !!!

Timing is everything, especially to physicists seeking to unite the mechanics of gravity with the quantum world of particles.

So when the opportunity came to measure if gamma rays of different energies traveled at the same speed, a team of physicists stepped up to the challenge.

At stake was nothing less than a foundation of modern physics -- Einstein's theory of relativity, which posits that all electromagnetic radiation travels at the same speed, whether low-energy radio waves, high-energy X-rays or gamma rays, or any wavelength in between.

A violent explosion 7.8 billion light-years away gave scientists the unique opportunity to punch a hole in Einstein's theory. NASA's Fermi Gamma Ray Telescope detected many gamma ray photons from the 2.1-second long burst, including one that was a million times more energetic than another.

Scientists wondered if the higher-energy photon might have arrived in the telescope's detector slightly later than its partner due to quantum-level entanglements in space that a less energetic photon wouldn't even notice.

"Some quantum gravity theories predict that the higher energy photons are more affected by the quantum nature of space-time and will travel more slowly than lower energy photons," said Stanford University's Peter Michelson, the lead scientist on the Fermi Large Area Telescope.

Michelson says it's kind of like the difference between a car and an ant traveling down a dirt road: The car isn't impacted by the pebbles and the rocks, whereas an ant has to go around every obstacle in its path.

After a journey of more than 7 billion light-years, however, the gamma ray photons arrived nine-tenths of a second apart on May 9, 2009 -- not enough of a lag to account for the theorized quantum effects.

"Einstein, at this point, wins again," Michelson said.

That's not to say that a theory of quantum gravity doesn't exist.

"It's a theory that would unify all the forces of nature," said Mario Livio, an astrophysicist with the Space Telescope Science Institute in Baltimore, Md.

"What Fermi has done here is push us to our limit," he added. "This only tells us where are the dead ends. It doesn't necessarily tell us where the correct way is."

The research was presented during a three-day symposium in Washington D.C. to highlight results of the telescope's first year of operations.(credit: discovery channel)
