If you are like most people, chances are that you have experienced déjà vu. French for ‘already seen’, it is that thrilling yet eerie feeling that you have encountered a situation or been to a place before, knowing fully well that it is not the case. For most people, the feeling is sudden and fleeting. But for a 23-year-old British resident it became a prolonged affair that lasted for over eight years....

We all know that music has the power to comfort us when we are frazzled or distressed. Can it do the same for animals? In 2001, University of Leicester researchers decided to test this by exposing dairy cows to different genres of music.

On April 1st, California's Governor Jerry Brown did what his predecessors have been doing for over 65 years - trek to Echo Summit in the Sierra Nevada Mountains to measure the snowpack. The only difference? Instead of ski gear he was wearing a light windbreaker and hiking shoes. That's because for the first time since the tradition began there was no snow to ski upon....

Plants typically use one of three methods to disperse seeds - wind, water, or animals. Not the Erodium cicutarium or as it is often called "stork's bill." This dynamic plant uses a powerful mechanism called "ballistic dispersal," to transport its seeds over 500 yards away. Though that is certainly impressive what happens after, is even more so....

Most of us could probably survive without spinach, kale, or broccoli, but a world without chocolate? Now that would be hard! But if some of the world's largest candy manufacturers are to be believed, it could happen if we don't act soon....

For humans seeing butterflies fluttering around with their beautiful brightly colored wings is a joyful sight. However not for their natural predators like lizards, spiders, and birds. To them, the vibrant hues are a reminder of a bad-tasting species that are best avoided. For those not easily duped, some butterflies also have eyespots on their wings. According to researchers, this tricks would-be predators into thinking that the insect is a larger animal, like an owl....

Most animals that hibernate during cold winter months have thick coats of fur or layers of fat to protect them. However, the Rana sylvatica species of the wood frog that can be found in Alaska and the Arctic Circle has neither. Therefore this tiny amphibian has adapted by freezing and thawing itself depending on the external temperature....

In 1996, Jan Scheuermann, a successful businesswoman and mother of two, began to notice her legs were not quite moving along with the rest of her body. A visit to the doctor revealed that she suffered from spinocerebellar degeneration, a rare genetic disease where the brain gradually loses connection to body muscles. By 2003, Jan had lost all ability to control her limbs and was paralyzed from the neck down....

Researchers have long suspected that hippos evolved from a family of plant-eating, semi-aquatic mammals called anthracotheres. The ancient animals that roamed freely all the way from North America to Asia inhabited Earth about 40 million years ago. However, scientists could never verify the theory since the only fossils of ancient hippos discovered thus far, dated back just 15 million years. Now thanks to Fabrice Lihoreau, there is finally some proof....

Pi Day that is celebrated on March 14th (3.14) annually, is always a significant occasion even for people that are not particularly fond of math. That's because while celebrations may begin with a discussion of the symbol, they invariably end with consuming different variations of Pi's yummy namesake - pie! However, this year promises to be even more special. That's because, for the first time and last time this century, the day will fall on 3/14/15, which happen to be the first five digits of Pi!...

The idea of riding a bike almost 4,000 miles across the country seems like an impossible task for most, but not for Elizabeth Case and Rachel Woods-Robinson. That's because these young scientists have a mission. They want to educate middle school students about physics and renewable energy and also encourage young girls to pursue careers in science....

While every dog owner knows that their pooch can discern their moods perfectly, scientists have always been a little skeptical. Now thanks to some researchers at the University of Veterinary Medicine in Vienna, Austria, we finally have some tangible evidence....

It all began innocently enough. On Thursday, February 26th, 21-year-old Scottish singer Caitlin McNeil posed a simple question along with a photo of a dress on the social media website, Tumblr. It said, “Guys, please help me - is this dress white and gold, or blue and black?”...

While whiteboards are great tools for educators and other speakers to use when explaining a concept, they can be distracting. That's because instead of paying attention to the speaker, the audience is often busy jotting down what's on the board before it is erased. Now, thanks to the ingenious Equil Smartmarker, the notes can be digitally captured and transmitted to a smart device, enabling the audience to focus their full attention to what's being said....

Seadragons may sound like mythical creatures from a fairy tale, but these tiny fish that are close cousins of seahorses and pipefish do exist. Found in the coastal waters off southern and western Australia, the gorgeous creatures that feed off tiny crustaceans, plankton, and larval fishes, do not have teeth or a stomach. They therefore, have to eat constantly and are always scouring the oceans in search of prey....

For over two decades, marine biologists have been listening to the songs from a whale that resides in the North Pacific. However, they have never heard a fellow mammal responding. That's because, unlike most whales that croon at a frequency of 15-20 hertz, this one sings at high pitched 52 hertz. As a result, this poor animal has never had a friend and, therefore, become known as the "world's loneliest whale!"...

Those of you that have suffered from dry eyes, severe allergies or experienced an infection know how difficult it is to apply eye drops. The most annoying part is that even after you have managed to administer the medicine, most of it streams out with the first blink. In fact, that is the reason doctors always recommend multiple applications. Now, some researchers have come up with a stick-on nanowafer that will alleviate the aggravation and also help heal faster....

But for all of the fun and whimsical items that can be produced, the most exciting application of this radical invention is the printing of artificial limbs. Its low cost structure makes it ideal for those that are unable to afford traditional prosthetics which can run tens of thousands of dollars....
