Though the US tornado season usually in begins in earnest from March and continues till June, things had been a little quiet this year, thanks to a cooler spring that lasted all the way through mid-May, keeping the twisters at bay. But as the temperatures and humidity have risen, the tornadoes have emerged with a deadly vengeance....

With their beautiful colors, upright swimming abilities and curled up tails, seahorses are magical creatures. Now it turns out, that these seemingly fragile fish are tough enough to weather impact that would destroy most living creatures - So much so, that researchers are planning to mimic their body structure to solve a problem that has been eluding them for many years....

On Thursday, May 9th, 2013, Federal scientists overseeing the oldest greenhouse gas monitoring system situated in Hawaii, reported that worldwide levels of carbon dioxide, the chief culprit behind global warming had reached 400 parts per million, a milestone never been encountered by humans before....

On Wednesday, May 1st, 2013, a group of nanophysicists from tech giant IBM unveiled their first production - A Boy And His Atom. However, the one-minute blockbuster that has already won the Guinness World Record Award for the smallest stop-motion film, is not an attempt by the tech company to get into the movie business, but a way to showcase future technology and more importantly, get young kids interested in a future in science, by demonstrating how fun it can be....

The fact that plants do not live a passive life has been known for sometime now. In 2012, a team of researchers led by Professor Nick Smirnoff from The University of Exeter, was able to visually prove that they communicate with each other and now two totally separate research studies reveal that these silent communicators may actually be 'talking' to each other and us!...

Cell phones have sure come a long way since the first 2.5 lb monster was unveiled just 40 years ago. Thanks to innovative companies like Apple Inc., we have evolved from keypad to touch-screen. But if you think that we are done with phone innovation, think again - Thanks to some Canadian inventors we may soon be swapping our rigid & thick (yes thick!), smart devices with flexible, paper-thin versions....

It weighs less than air and is extremely strong, yet flexible enough to bounce back to its original shape, after being compressed. And, it does not float away either, because a 10cm×10cm×10cm cube does not displace 1000 cubic centimeters of air, since a lot of air stays in the pores of the 'sponge'. But best of all, it can absorb up to 250-500 times its own weight of oil at a rapid pace of 68.8 grams per second. This is not a material scientist's dream, but a description of the most recent 'lightest' solid created by a research team from China's Zheijang University....

It is a well-documented fact that humpback whales gather their prey by creating 'bubble nets'- that is, blow bubbles underwater to confuse shoals of fish and cause them to herd together, giving the whales a perfect opportunity to devour them in one gulp....

On February 8th 2013, scientists from European Space Agency (ESA) announced that their weather satellite that is equipped with an instrument specifically designed to sense ozone concentrations showed revealed the seasonal ozone 'hole' above the Antarctica had shrunk to record levels!...

Coral reefs are not just beautiful to look at, but also, extremely useful. Considered the marine equivalent of tropical rainforests, they cover only 2% of the ocean bottom but harbor almost 25% of all marine life. However, like many other species, this amazing ecosystem that has been around for five hundred million years is in danger of being eradicated completely, if something is not done soon....

In February 2013, US multimillionaire Dennis Tito announced that his non-profit organization, Inspiration Mars Foundation, was planning to sponsor two 'qualified' people for a flyby to Mars in 2018. While one would think that an announcement this ambitious from a man whose closest encounter with Space has been as the first paying guest of the International Space Station would arouse some skepticism, such is not the case....

While ants may appear to be just pesky insects whose sole purpose in life is to annoy humans, they are in reality, quite amazing - they can survive the biggest floods by morphing into living rafts, find their way anywhere, thanks to a built-in GPS and now it turns out, may even have the ability to predict earthquakes - Something even the world's best brains have been unable to do so far!...

Though it is common knowledge that lack of gravity makes life in space a tad different from that on earth, very few of us ever think about how different. There is of course the fact that Astronauts are always suspended and floating around, but what about beyond that? Something as basic as shedding a tear or two of joy or sorrow?...

After being slammed by severe winter storms, some areas of the East Coast of the United States are now getting ready for another onslaught - This time, from the millions of cicadas that are about to emerge from the ground for the final three months of their lives....

Last week, Japan's Tokyo Sea Life Park unveiled its latest exhibit - A transparent fish that has no scales and clear blood. The specimen of the Ocellated Ice Fish, believed to be the only one of its kind in captivity, was brought to the center by Japanese krill fisherman in 2011....

A 2005 study by the U.S. Dept. of Agriculture Forest Service revealed that over 80 million birds are killed each year due to collisions with motor vehicles. However, one smart bird species that resides in some areas of the Western United States like Nebraska, seems to be bucking the trend and if two researchers are to be believed, it is all to do with evolution....

'Green' or environmentally responsible buildings that use minimal resources by depending on solar energy or recycled water are becoming increasingly common. However, the Torre de Especialidades Tower currently being constructed as an extension of a hospital in Mexico City, is taking that concept to a whole new level, with a new innovative tile that is capable of absorbing pollution from the atmosphere....

The image of a fresh vegetable garden in subarctic weather may be a little difficult to conjure up. However, believe it or not, thanks to global warming this is not as rare a sight and as years go by, one that may become increasingly common especially, in areas like Greenland....

Last year's spectacular London Summer Olympic games may seem like an event of the past, but its legacy is still manifesting itself in impressive ways. 'Speed of Light,' an art performance combining technology and athleticism to showcase the travel of light using human generated kinetic energy, is one of the most stunning examples....

If you are planning to fly from New York City to Amsterdam aboard KLM airlines sometime soon, you may want to bring along some fries or fried catfish - Not because the airline has decided to stop feeding its passengers, but because mixed in with the normal jet fuel is cooking or biofuel from the kitchens of Louisiana!...

Humans are naturally curious - They like to seek out the wildest adventures even if it means intruding on the habitats and lives of other species. Nowhere is this fact more obvious than Stingray City in the Cayman Islands.

We all know that coffee can get humans all wired up and active, but powering a truck? That has to be a first! However, it is what engineer Martin Bacon and a group of volunteers from Teesdale Conservation in Durham, England were able to successfully demonstrate, on February, 19th, 2013....

While many companies have attempted to create gesture controlled devices, there are as intuitive as Leap Motion, which uses actions that come naturally to computer users effectively, putting the control right at their fingertips!...
