Camouflage is not a new concept in the animal kingdom. From grasshoppers blending in with leaves to owls mimicking tree barks, many animals, birds, and insects, depend on their ability to hide in plain sight for survival. But if there were an Oscar for the species with the best disguise, it would surely go to the dusky dottyback. The crafty predator fish can change its color to mimic that of its prey's parents, allowing it to feast on their juveniles, without raising suspicion....

Food waste is a growing concern. According to a recent report by the United Nations Environmental Programme, consumers in industrialized countries waste as much as 222 million tons of food annually. To put it in perspective, that is almost equivalent to the net food production of sub-Saharan Africa. Now the residents of the small Spanish town of Galdakao have devised a simple solution to help reverse the trend - a community refrigerator!...

Every year about this time, stargazers start to get excited about the Perseids, the biggest and most spectacular of all meteor showers. The "shooting stars" are already streaming through our skies at the rate of about a dozen an hour. However, from August 11 to 14, the pace will accelerate to almost a hundred an hour, making them fairly easy to spot even without a telescope. The best part is that unlike last year, there will be no "super" supermoon to steal their thunder....

To the novice listener, the Australian Chestnut-crowned babbler's sweet melodies may sound like any other birdsong. However, to ornithologists it is a series of sounds which when combined, forms a unique bird-like vocalization or what we refer to as language. The discovery is exciting because the tiny birds are the first nonhuman species known to communicate using language....

Often the most incredible innovations come in the tiniest packages. That is certainly true for the origami robots created by some Massachusetts Institute of Technology (MIT) researchers. The microbots that made their debut earlier this summer at the International Conference on Robotics and Automation in Seattle, WA, are not just adorable. They also possess skills that may come in handy to combat human ailments....

Cheers erupted at "Plutopalooza" parties all across the United States as the New Horizons spacecraft soared past the dwarf planet at 7:49 am EDT on Tuesday, July 14th.

In late April and early June, two giant eel-like fish washed ashore on the beaches of Aramoana, New Zealand and Catalina Island, California. Known as oarfish or Regalecus russelii, the colossal deep-sea creatures that measured 10-feet and 17-feet long respectively, are a rare sight. Hence the news of two appearing almost simultaneously caused much excitement and also a little trepidation....

Some people like to grow fruits, others prefer to focus on vegetables. Then there is Gavin Munro, who is partial to cultivating furniture. No, he is not a scientist with a crazy idea, but an ordinary man who is living his dream of growing "green" chairs!...

Recreation Vehicles (RV's) or mobile homes are an excellent way to travel around the world and experience life like a local. It is no wonder that they are getting increasingly popular not just with vacationers but also retirees and seasonal workers. The only drawbacks are that these gas-guzzling homes on wheels are not very environmentally friendly and also somewhat restrictive. That's because they depend on the grid for water and electricity....

The human tendency to gravitate towards people that are similar to them starts early. In school-age children, the behavior called homophily, or "love of the same" often has to do with how others dress or act. Adults tend to form groups based on social stature, professions or personalities. Turns out that forming cliques and shutting out those that are "different" is not just a human trait. South Africa's Chacma or Cape baboons display similar tendencies as well!...

While e-books are on the rise, most people, especially young kids, still prefer printed versions that they can pore over for hours on end. Though that is an excellent habit, it also means cutting down precious trees. But what if the book could revert to its roots and transform back into a tree? Now thanks to a Brazilian children's book publisher, that is possible, at least for one book!...

The Port of Astoria in Oregon is battling an unusual challenge - how to rid the area of the over 2,300 sea lions that have taken up residence on the piers, without harming them.

Lost Lake in Central Oregon is a mysterious natural wonder. During winter, it resembles any other large body of freshwater. However, as drier weather kicks in the water disappears, transforming the 85-acre 'lake' into a beautiful meadow. Turns out that there is a logical answer to this magical phenomenon - a tube or tunnel created by an ancient lava flow that drains out the water....

The Opah is a striking fish species that can grow as large as 7-feet in diameter and weigh over 100 pounds. Also referred to as moonfish, the giants that can be found in both temperate and tropical seas reside at depths of 150 to 1,300-feet where the waters can be extremely chilly. Scientists have often wondered how the fish can withstand the temperatures given that they lack typical deep sea dweller characteristics like a large heart. Now thanks to some curious California researchers that mystery has finally been solved - The Opah has warm-blood!...

Similar to humans, produce comes in different shapes and sizes. Yet, chances are you have probably never encountered a gnarly looking carrot or an apple with "character" at your local grocery store or farmers market. That's because any fruit or vegetable that looks different from what is considered "normal" is deemed undesirable and automatically tossed out!...

Creating a "green" or carbon neutral fuel to replace gasoline has been the holy grail for scientists for many years. However, while there has been some progress with inventions like electric batteries and biofuel, most options are either too expensive or not commercially viable to compete effectively with the fossil fuel. Now automobile manufacturer Audi is stepping up to the challenge with diesel made from carbon dioxide and water....

Though there are numerous saltwater lakes around the world, none can compare to the Dead Sea. Located between Israel and Jordan in the Middle East, the water of this landlocked lake boasts salt levels almost ten times that of oceans. The unusual salinity can be attributed to the fact that there is no outlet for the minerals to leave, causing them to accumulate. The same is not true of the water level, which remains constant due an almost even inflow from the Jordan River and loss through evaporation....

Over the years, numerous animal and bird species have become extinct. However, it is rare for the entire world to witness one as it is happening. This could very well be the case with the northern white rhinos given that there are currently only five known specimens left. What's worse is that only one, a 42-year-old named Sudan is male! If he passes away without producing an offspring, the rhino sub-species will soon disappear....
