How To Unboil An Egg ?

Have you ever thought of unboiling a boiled egg? Scientists have figured out a way to do exactly the same. Here is what it is..

When you boil an egg, the heat causes the proteins inside the egg white to tangle and clump together, solidifying it. A new research published in ChemBioChem by scientists at UC Irvine shows how they can essentially reverse the clumping process by adding chemicals to a cooked egg.

“Yes, we have invented a way to unboil a hen egg,” UCI biochemist Gregory Weiss said in a statement.

Are We On the Brink of Finding a Second Earth?

"It could happen almost any time now. We now have the technological capability to identify Earth-like planets around the smallest stars." says NASA/Harvard Teams

To date, Planet hunters have spotted more than 200 planets beyond our solar system, but the vast majority are hot, Jupiter-sized planets that would dwarf the Earth and are almost certainly lifeless.

Astronomers may be on the brink of discovering a second Earth-like planet, a find that would add fresh impetus to the search for extraterrestrial life, according to the US journal Science. Astronomers from six major centers, including NASA, Harvard and the University of Colorado, outline how advances in technology suggest scientists are on the verge of being able to detect the presence of small, rocky planets, much like our own, around distant stars for the first time. The planets are considered the most likely habitats for extraterrestrial life.

One technique relies on observing the shift in light coming from a star as a planet swings around it. Until recently, this "radial velocity" method has only been sensitive enough to pick up planets far more massive than Earth, but improvements now make the discovery of a second Earth highly likely, said Dave Latham, a co-author on the paper at the Harvard-Smithsonian Center for Astrophysics.

"It could happen almost any time now. We have the technological capability to identify Earth-like planets around the smallest stars even now," he said.

Earlier this year, the world's largest and most prolific team of planet hunters, the Anglo-Australian, California and Carnegie Planet Searches ( AAPS), reported their findings of 37 exoplanets that have been discovered over the past couple of years, 7 of which were previously unreported brown dwarfs.

Depending on whose number you go by, the total number of exoplanets currently discovered is 212 or 240, the majority of which have been discovered by the AAPS and their colleagues in the California and Carnegie searches.

Is the world going to end ?

Apparently, the world is going to end on December 21st, 2012. Yes, you read correctly, in some way, shape or form, the Earth (or at least a large portion of humans on the planet) will cease to exist. Stop planning your careers, don't bother buying a house, and be sure to spend the last years of your life doing something you always wanted to do but never had the time. Now you have the time, to enjoy yourselves before… the end.

So what is all this crazy talk? We've all heard these doomsday predictions before, we're still here, and the planet is still here, why is 2012 so important? Well, the Mayan calendar stops at the end of the year 2012, churning up all sorts of religious, scientific, astrological and historic reasons why this calendar foretells the end of life as we know it. The Mayan Prophecy is gaining strength and appears to be worrying people in all areas of society. Forget Nostradamus, forget the Y2K bug, forget the credit crunch, this event is predicted to be huge and many wholeheartedly believe this is going to happen for real. Planet X could even be making a comeback.

Light in Reverse Gear - The backward moving pulse

Ever thought of reversing the light?? Yeah thats not a trick , not at all
In the recent years scientists have started to "PUSH LIGHT INTO REVERSE". Hey that in no way turning off the lights (haha!!)

From everybody's knowing and common sense light is known to travel fastest. And according to Einstein if something could move faster than that , then it can be seen reaching its destination before it left its starting position. Laugh !!! LOL .. think how can that be possible. So according to him nothing can do that

But researchers found that "back-ward moving pulse of light is faster" than that. Pretty Confused !!

Yeah!! Now that is putting light into the reverse gear. So everything now seems to have reverse gear. Read more at : Light’s most exotic trick yet: so fast it goes backwards?

The article is as below:

In the past few years, physicists have found ways to make light go both faster and slower than its usual speed limit. Now researchers say they’ve gone a step further: pushing light into reverse. As if to defy common sense, they say, the backward-moving pulse of light travels faster than light. Confused? You’re not alone. “I’ve had some of the world’s experts scratching their heads over this one,” said Robert Boyd of the University of Rochester in Rochester, N.Y., one of the researchers. “It’s weird stuff.” “Theory predicted that we could send light backwards, but nobody knew if the theory would hold up or even if it could be observed in laboratory conditions.” Einstein determined that nothing can be accelerated to a speed greater than that of light in a vacuum. That’s about 300,000 kilometers (190,000 miles) per second. If something broke that limit, then some observers could see it reach its destination before it left, violating a universal law of causality. But physicists in recent years have reported finding tricks to slow light to a near-standstill, or even speed it up in apparent violation of Einstein’s rule. Now, Boyd said, he’s taken what was once just a mathematical oddity—negative speed—and shown it working in the real world. The findings are published in the May 12 issue of the research journal Science. Boyd and colleagues sent bursts of laser light through an optical fiber laced with the element erbium. An optical fiber is a thin, transparent tube that transmits light by letting it bounce along its interior. “The pulse of light is shaped like a hump with a peak,” Boyd explained. “We sent a pulse through an optical fiber, and before its peak even entered the fiber, it was exiting the other end. Through experiments we were able to see that the pulse inside the fiber was actually moving backward.” To understand how light’s speed can be manipulated, think of a funhouse mirror that makes you look fatter. As you first walk by the mirror, you look normal. But as you pass the curved portion in the center, your reflection stretches. The far edge seems to leap ahead of you momentarily. In the same way, a pulse of light fired through a special material may move at normal speed until it hits the substance, where it is stretched out to reach and exit the material’s other side . Conversely, if the funhouse mirror were the type that made you look skinny, your reflection would appear to suddenly squish together, with the leading edge of your reflection slowing as you passed the curved section. Similarly, a light pulse can be made to contract and slow inside a material, exiting the other side later than it naturally would. To visualize the backward-moving light pulse reported by Boyd, replace the mirror with a TV and video camera. As you may have noticed when passing such a display in an electronics store window, as you walk past the camera, your on-screen image appears on the opposite side of the TV. The image walks in the direction opposite to yours, and thus toward you. It passes you in the middle, and continues until it exits the other side of the screen.
