First Ever 'Logic Gate' made out of Bacteria

Thinking of upgrading your PC or increasing your hard disk space and you are out of money. Take no worries now. As the scientists in imperial college of london have come up with a way of creating the logic gates out of bacteria. Yup! you heard it right. 'Bacteria'.


The scientists constructed a type of logic gate called an “AND Gate” from bacteria called Escherichia coli (E.Coli), which is normally found in the lower intestine. The team altered the E.Coli with modified DNA, which reprogrammed it to perform the same switching on and off process as its electronic equivalent when stimulated by chemicals.


The days are not that far now when you can harvest bacteria at your home to increase your PC's GB by breeding bacteria. The researchers claim that they are the first one to make bacterial logic gates, which can be sorted out to make more complex logic gates and a possibility of creating a biological processor.

E-Coli bacteria used

Researchers belive that not only they could one day be used as part of a PC's processor but may one day be used in the human body to kill the cancer cells and clear our arteries.

Einstein was Wrong > E=mc2 is Wrong

9/27/2011 11:33:00 PM Science, Tech News 1 Comment

Einstein was Wrong >> E=mc2 is Wrong


Albert Einstein was always valued above all scientists because of his special theory of relativity — but now new research in Switzerland and Italy suggests that Einstein might have been wrong. OPERA, an international group of physicists at CERN's particle accelerator outside Geneva, claims that they have tested that neutrinos can travel faster than the speed of light — which is contrary to what Einstein believed and mentioned under his theory that light being the only entity in the universe that can travel at the highest speed.

Here is a brief information that you should know

What are neutrinos?
Neutrinos are virtually invisible, shape-shifting particles. They're "among the weirdest denizens of the weird quantum subatomic world,". And they travel effortlessly "through walls and planets like wind through a screen door." Over three years, the OPERA team fired 15,000 beams of neutrinos underground from CERN to the subterranean Gran Sasso laboratory south of Rome — primarily to study the shifting properties of neutrinos, not the speed at which they travel. But their speed "is becoming a main issue," says OPERA leader Antonio Ereditato, dryly.

How much faster than light did the neutrinos travel?
Light travels the 454 miles from CERN to Gran Sasso in 2.4 thousandths of a second, and the neutrinos beat that time by 60 nanoseconds, or 60 billionths of a second, the scientists say. "You could say it's peanuts, but it's not," says Ereditato, "It's something that we can measure rather accurately with a small uncertainty."

How does this challenge Einstein?
Einstein's 1905 special theory of relativity states that c, the speed of light, is a sort of "cosmic speed limit" — that nothing in the universe moves faster than light, which travels at 186,282 miles per second. That idea is a key foundation of modern physics, and it has withstood more than 100 years of intense scrutiny.

Could the OPERA team be wrong?
The OPERA team spent six months trying to find holes in its research, but "the finding is so startling that, for the moment, everybody should be very prudent," says Ereditato, who suspects human error is responsible for the shocking result.

And what if Einstein is wrong?
The biggest implication might be that time travel would be theoretically possible. The average person "could, in principle, travel to the past and kill their mother before they were born," says De Rujula. For his part, Ereditato is avoiding dwelling on what the demotion of light could mean. "We will continue our studies and we will wait patiently for the confirmation," he says. "Everybody is free to do what they want: To think, to claim, to dream." At least for now, he adds, "I'm not going to tell you my dreams."

Watch Out: NASA Satellite Falling Tonight on Earth

9/23/2011 06:00:00 PM Astronomy, Space No Comments

Watch Your Heads, NASA Satellite is going to fall today- Friday 23, Sept 2011

A satellite is falling down on earth as the fuel for the satellite has ended months ago. The falling satellite is speeding towards earth with the speed of 18,000mph(28 968.192 km/h). The satellite could fall anywhere excluding North America

The satellite is almost the size of a bus, and will break up due to air resistance upon entering Earth atmosphere. Huge chunks(around 26 pieces) of the metal may weight up to 350lb(350kg) and will all across hundred of miles. Please see the blow picture for the best guess where the satellite pars could land.

Satellite parts could land any where in between the lines.

NASA said it will only know two hours before impact where it will land – and even that prediction will only be accurate to the nearest 6,000 miles. It could be anywhere between the 57th parallel north, which crosses Britain, and the 57th parallel south, which passes just below South America.

Ever Imagined: A planet orbiting two suns

Ever Imagined: A planet orbiting two suns

Discovered for the first time a planet orbiting a binary star system, passing in front of both its parent stars along its orbit

The planet, Kepler-16b, resembles Saturn in its mass and gaseous makeup. That mostly rules out the possibility of any living beings being present to enjoy the double sunset view, although chances are good Kepler-16b has an icy, non-gaseous satellite or two, as Saturn does.

If any one of you has watched Starts wars Episode IV, they might have imagined how beautiful the scene could be as predicted , incase some one missed those scenes, they can watch the below video

Lab Builds a Fully Functioning Artificial Small Intestine

7/07/2011 02:45:00 PM Research 1 Comment

Small Intestine in LAB(ready for implant)

California researchers have created a tissue-engineered small-scale small intestine in mice, a breakthrough for regenerative medicine and a step toward growing new intestines for humans. The process re-creates all the layers of cells that make up a functioning intestine.
New small intestines grew on the scaffold, the researchers say, and they had all the constituents of a normal intestine. The new intestines “contained the most essential components of the originals,” according to the news release.

The research could someday be used to treat various intestinal disorders, including a particular gastrointestinal disease that affects premature babies, according to Children’s Hospital. An engineered replacement organ would conceivably last much longer than a transplant, if one is even available.

Stuxnet - A cyber Nuclear Weapon

6/29/2011 12:38:00 PM Research, Science 1 Comment

Stuxnet - A cyber Warhead

The Stuxnet computer virus, created to sabotage Iran's nuclear programme, was the result of collaboration between at least one Western power and the Israeli secret service, a British cyber security expert has found.A highly sophisticated computer worm that has spread through Iran, Indonesia and India was built to destroy operations at one target: possibly Iran's Bushehr nuclear reactor.

Experts had first thought that Stuxnet was written to steal industrial secrets -- factory formulas that could be used to build counterfeit products. But Langner found something quite different. The worm actually looks for very specific Siemens settings -- a kind of fingerprint that tells it that it has been installed on a very specific Programmable Logic Controller (PLC) device -- and then it injects its own code into that system.


When Stuxnet finally identifies its target, it makes changes to a piece of Siemens code called Organizational Block 35. This Siemens component monitors critical factory operations -- things that need a response within 100 milliseconds. By messing with Operational Block 35, Stuxnet could easily cause a refinery's centrifuge to malfunction, but it could be used to hit other targets too, Byres said. "The only thing I can say is that it is something designed to go bang

A study of the spread of Stuxnet by Symantec showed that the main affected countries in the early days of the infection were Iran, Indonesia and India:
CountryInfected computers
Iran 58.85%
Indonesia 18.22%
India 8.31%
Azerbaijan 2.57%
United States 1.56%
Pakistan 1.28%
Others 9.2%

The Real Shape of the Earth- (forget 6th grade Earth shape)

4/05/2011 05:58:00 PM Space 3 Comments

Giant potato in space.

And yet, the information in this model is the sharpest view we have of how gravity varies across the Earth.
The globe has been released by the team working on Europe's Goce satellite. It is a highly exaggerated rendering, but it neatly illustrates how the tug we feel from the mass of rock under our feet is not the same in every location. Gravity is strongest in yellow areas; it is weakest in blue one.


Scientists say the data gathered by the super-sleek space probe is bringing a step change in our understanding of the force that pulls us downwards and the way it is shaping some key processes on Earth.Chief among these new insights is a clearer view of how the oceans are moving and how they redistribute the heat from the Sun around the world - information that is paramount to climate studies.

Those interested in earthquakes are also poring over the Goce results. The giant jolt that struck Japan this month and Chile last year occurred because huge masses of rock suddenly moved. Goce should reveal a three-dimensional view of what was going on inside the Earth.

"Even though these quakes resulted from big movements in the Earth, at the altitude of the satellite the signals are very small. But we should still seem them in the data," said Dr Johannes Bouman from the German Geodetic Research Institute (DGFI).
