In addition, having a sensor which doesn't need batteries could be extremely useful to the military and police sampling air for potential bioterrorism attacks in the United States, Wang says.

While biosensors have been miniaturized and can be implanted under the skin, he points out that these devices still require batteries, and the new nanogenerator would offer much more flexibility. A major advantage of this new technology is that many nanogenerators can produce electricity continuously and simultaneously. On the other hand, the greatest challenge in developing these nanogenerators is to improve the output voltage and power, he says.

Last year Wang's group presented a study on nanogenerators driven by ultrasound. Today's research represents a much broader application of nanogenerators as driven by low-frequency body movement. Delivering all the performance of a desktop, enabled in a revolutionary, sleek, and killer notebook.

Here we see the leaked photos and information about the Nokia N97, the next-generation of powerhouse multimedia packed cellular phones which is still in infancy.

Rumour say that the N97 cellular phone which we would prefer to name as prince of GSM cellular phone, will comes with 3-inch huge display screen, a 5-megapixel camera with 20x zoom who needs 20x zoom? Scientists and engineers who have been working on the James Webb Space Telescope mission for years are getting very excited, because some of the actual pieces that will fly aboard the Webb telescope are now being built.

One of the pieces, called the Backplane, is like a "spine" to the telescope. Not only will the Backplane be carrying a large mirror, but it will be supporting a lot of weight. Being the "spine" of the mirror requires it to essentially be motionless while the mirrors move to see far into deep space. Imagine holding the handle of a magnifying glass to see a tiny object. If your hand shakes a lot, it will be hard to focus on the object.

So, just as you have to hold the magnifying glass handle steady with your hand, the Webb backplane has to hold the telescope mirrors steady, to allow them to focus. The Backplane is made with advanced graphite composite materials mated to titanium and invar fittings and interfaces.

Invar is a nickel steel alloy notable for its uniquely low changes due to thermal expansion. It will be completed and delivered to Northrop Grumman in late for integration into the Webb telescope.

The James Webb Space Telescope is expected to launch in By observing in infrared light, it will be able to see faint and very distant objects, explore distant galaxies, formation of star systems, and nearby planets and stars. Webb will be able to see "back in time" to the first light after the Big Bang. The information it will send back to Earth will give scientists clues about the formation of the universe and the evolution of our own solar system. ATK is a key partner with Northrop Grumman.

Giant Solar Twists Discovered. Scientists at Queen's University have made a finding that will help us to understand more about the turbulent solar weather and its effect on our planet.

Along with scientists at the University of Sheffield and California State University, the researchers have detected giant twisting waves in the lower atmosphere of the Sun. The images also contain some surprises — interlopers both far and near. Sometimes objects in the sky that appear strange, or different from normal, have a story to tell and prove scientifically very rewarding.

The image proves to contain several surprises. Arp lies about 70 million light-years distant in the constellation of Libra, the Scales. Its chaotic and very unusual structure is created by the interaction of two galaxies that are engaged in a slow motion, but highly disruptive close encounter. Although individual stars are very unlikely to collide in such an event, the huge clouds of gas and dust certainly do crash into each other at high speed, leading to the formation of bright new clusters of very hot stars that are clearly seen in the picture.

The paths of the existing stars in the galaxies are also dramatically disrupted, creating the faint swirls extending to the upper left and lower right of the image. Both interacting galaxies were probably dwarfs not unlike the Magellanic Clouds orbiting our own galaxy.

The images used to create this picture were not actually taken to study the interacting galaxies at all, but to investigate the properties of the inconspicuous object just to the right of the brightest part of Arp and close to the centre of the image. This is an unusual exploding star, called SN N, that is thought to be the result of the final collapse of a massive star at the end of its life, a so-called core collapse supernova.

SN N is unusual because it has faded very slowly — and still shows clearly on this image more than seven years after the explosion took place! It is also one of the few supernovae to have been observed to emit X-rays. It is thought that these unusual characteristics are a result of the exploding star being in a dense region of space so that the material blasted out from the supernova ploughs into it and creates X-rays.

Apart from the interacting galaxy and its supernova the image also contains several other objects at wildly different distances from us. Starting very close to home, two small asteroids, in our Solar System between the orbits of Mars and Jupiter, happened to cross the images as they were being taken and show up as the red-green-blue trails at the left and top of the picture. The trails arise as the objects are moving during the exposures and also between the exposures through different coloured filters.

The asteroid at the top is number and the one to the left number They are probably less than 5 km across. The reflected sunlight from these small bodies takes about fifteen minutes to get to the Earth.

The next closest object is probably the apparently bright star at the bottom. It may look bright, but it is still about one hundred times too faint to be seen with the unaided eye. It is most likely a star rather like the Sun and about light-years from us — 20 million times further away than the asteroids.

Arp itself, and the supernova, are about times further away again than this star, but still in what astronomers would regard as our cosmic neighbourhood. Much more distant still, perhaps some fifty to one hundred times further away than Arp , lies the cluster of galaxies visible on the right of the picture. There is no doubt, however, that a much more remote object lies, unrecognised, amongst the faint background objects seen in this marvellous image.

Just as no two humans are the same, a Purdue University scientist has shown treating mice more as individuals in laboratory testing cuts down on erroneous results and could significantly reduce the cost of drug development. Mice have long been used as test subjects for treatments and drugs before those products are approved for human testing. But new research shows that the customary practice of standardizing mice by trying to limit environmental variation in laboratories actually increases the chance of getting an incorrect result.

It suggests scientists should change their methods and test mice in deliberately varying environmental conditions. Garner said that will decrease the number of false positive test results and eliminate further costly testing of drugs or treatments destined to fail.

You want to know if a drug is going to work in all people, so you test it on a wide range of different people. We should do the same thing with mice. But scientists often use mice that are basically genetically identical and try to limit internal and external environmental factors such as stress, diet and age to eliminate variables affecting the outcome.

Garner said there is no practical way to ensure that all environmental conditions are the same with mice, however, because they respond to cues humans cannot detect. For example, a researcher's odor in one lab might cause more stress for a mouse than another researcher's odor in a second lab with different mice, giving different results.

But scientists, unaware of the odor difference, may believe a treatment worked when the mice were actually responding to an environmental cue, giving a false positive. The study used three different strains of mice from previously published data and compared their behavioral characteristics against each other. The observations were done in three different labs, two different types of cages and at three different times to make 18 different replicates of the same experiment.

Traditional testing theories say the results should have been the same in all those experiments. Once the results were compared, however, the researchers found many false positives, or instances when one strain appeared to act differently from another when it actually should not. So they reevaluated the data, picking a mouse of each strain from each environment - similar to matching pairs in human clinical trials - and found only the same number of false positives as would be expected by chance.

When mouse testing creates a false positive, leading a researcher to believe a drug has worked, the drug could be sent to further animal testing and human clinical trials at a cost of millions of dollars.

Drugs that fail in clinical trials cannot be marketed, and the money is wasted. To recoup those losses, drug companies must increase the costs of marketable drugs. Numbers are hard to estimate, but for every drug that reaches the marketplace, well over have been abandoned at some point in their development. Weeding out an unsuccessful drug would eliminate an unnecessary second round of animal testing.

Their research will now focus on which environmental factors have the most impact on results. Scientists Fine-tunes Hubble Space Telescope. A scientist at Rochester Institute of Technology has expanded the Hubble Space Telescope's capability without the need for new instruments or billions of dollars.

Dan Batcheldor and his team improved the calibration of Hubble's Near-Infrared Camera and Multi-Object Spectrometer to enable high-precision polarimetry. Scientists like Batcheldor use this observational technique to read scattered light when investigating active galactic nuclei and for identifying proto-planets around very young stars.

The findings of the nine-orbit calibration plan, funded by the Space Telescope Science Institute, were published in the February issue of Publications of the Astronomical Society of the Pacific.

Carlson Center for Imaging Science. What a polaroid does is it makes you see only light aligned in a certain way. The scattering material acts like a mirror, allowing scientists to look into the center of these astronomical objects. And so now Hubble can do this even if only one percent of the light is polarized. Limitations caused by the previous calibration stalled his investigation of active galactic nuclei and needed to be fixed before he could continue his research. Follow us on Twitter.
