Operating on the eye, especially for things like retina repairs is one of the riskiest surgeries doctors perform - One where even a slight tremble of the hand could cost the patient his/her eyesight. Even experienced ophthalmologists who perform the surgery do it for only a limited number of years stopping, when they start to age. Now, a researcher has come up with a smart solution - A robotic assistant that does all the delicate work without ever flinching!...

The beautiful oceans that cover three-quarters of our planet are home to some of our most valuable natural resources. However, while our knowledge of outer space is quite extensive, the same cannot be said about the deep waters, thanks to the fact that any attempts to monitor them has either been too cumbersome or too expensive. Now, California-based Liquid Robotics has come up with an innovative invention that is both economical and easily deployable across the waters....

The unassuming gecko - That tiny lizard that seems to scamper around any surface in gravity-defying positions, has intrigued scientists for many years. In the past, this amazing ability has been duplicated by researchers to create wall-scaling robots and now, a team of scientists from Germany have come up with a gecko inspired adhesive tape, that can be re-used thousands of times....

The next time you are being told off for wasting time playing video games, inform your parents that you are merely trying to fire up your imagination and get your creative juices going. At least that's what a recent study performed by the University of Michigan, seems to have concluded....

On June 3rd 2010, six brave astronauts bid adieu to their family and friends and launched off to Mars - This of course was not an actual mission to the Red Planet, but a simulated journey that entailed confining them inside a sealed five-capsule 1000sq.ft. unit, for 520 days....

While we have integrated technology in almost every aspect of our lives, the clothes we don have so far, been spared - Now, a Southern California company is trying to change that with a new hi-tech fabric that will not only help athletes improve their performance, but also, help heal wounds and chronic ailments like arthritis....

Ants are industrious little insects that always seem to know where they are heading - Now, a team of curious researchers from the Technical University of Munich and Brazilian Center for Physics Research believe they may have the answer - It's all to do with their in-built GPS systems....

Most of us think of the Octopus as an eight-legged mollusk that spends its days wriggling around with its snake-like arms. However, not only does this intelligent animal have a razor-sharp memory, it has also, been known to maneuver through mazes and even try escape from tanks....

The threat of dead satellites freefalling from Space seems to have become a regular event these days. A month ago, it was American satellite UARS. Last weekend, we were all waiting to see where German satellite ROSAT would end up - Turns out that it too landed, without causing any casualties....

Ken Nedimyer first dived into the pristine waters off the Florida Keys at the tender age of 13, whilst on vacation with his parents. He enjoyed it so much, that he returned in 1969 to obtain a degree in Zoology from the Florida Atlantic University and never left....

About three weeks ago, we all awaited with abated breath as American satellite UARS hurtled back to earth - Fortunately, it crashed in such a remote area that it took the scientists three days to locate the debris. Now, another satellite is making its way back and once again, scientists have no clue where the debris will end up!...

Of all the dinosaurs known to mankind, it is the Tyrannosaurus Rex or T-Rex that captures our imagination the most, probably because it was the biggest and fiercest of them all. Now, a new study claims that we may have underestimated its size and weight by as much as, 30 percent...

The question of whether there is any form of life on other planets in our Universe has been plaguing humans for centuries - Now, the search is about to get even more intense, thanks to an ultra-large, uber-sophisticated telescope, innovatively dubbed - European Extremely Large Telescope or E-ELT!...

The oceans surrounding the coastal city of San Diego, California are known to be warm, crystal clear and . . . . . . . Bioluminescent? At least that's what they have been for the last few weeks and the residents seem to be enjoying every moment of it....

One of the best parts in Disney's Aladdin is watching him and Princess Jasmine flying around on Aladdin's magical carpet. Now, a Princeton student has invented a prototype that could some day, turn into a real-life flying carpet....

Finding a green fuel that is cheap and plentiful enough to replace fossil fuels is one of the biggest challenges that humans face - Not only because of the global warming issues, but also, because fossil fuels are a finite source. While hydrogen is a viable replacement, it does not occur naturally and to produce it, takes energy from 'dirty' fossil fuels - Now, there may be a solution....

Last week, people all over the world fretted over the fact that NASA's 6.5 ton Upper Atmosphere Research Satellite (UARS) was hurtling back to earth and the Space Agency had no clue or control over when and where it would crash land....

The hierarchical structure that exists within bee colonies has always been a source of fascination for researchers. The biggest mystery? With tens of thousands of identical members in each colony, how do just a handful get selected to be Queen bee(s), while the rest get relegated to being workers?...

Over the years we have sent so many unreturnable rockets, satellites and other devices to the outer atmostphere, that 'Space Junk' is becoming a big concern among the experts, given that they could freefall to earth any time - This week, their worst fears will be realized....

The reason humans are considered to be at the top of the food chain is to do with inteligence, which is measured by their ability to build and use complex tools to solve day-to-day issues. However, recent research has revealed that a number of animals also display similarly intelligent behavior....

Access to cheap and plentiful electricity is something most of us take for granted. However, such is not the case in many parts of the world, especially in third world countries, where the poor live in shanty homes that are often constructed from cardboard or other flimsy materials....

The quest to develop faster microprocessors - the tiny silicon chips that allow your computers do all the magical things they do - is never ending, with chip manufactures spending millions of dollars in research each year. In the past, they have succeeded in doubling the processing speed roughly every two years, by simply shrinking the size of the transistors, so that more could be fitted onto each microchip....

The fact that plants absorb harmful carbon dioxide and emit oxygen that humans need to survive, has been well documented for many years now. Despite that, we seem to continue to treat plants like second-class citizens - Something geologist Iaian Stewart is trying to change, by spending 48-hours inside a sealed box....
