Australia is home to some of the world's deadliest animals. However, few are as dangerous as the cane toad. Native to Central and South America, the innocent looking amphibian is an invasive species that was imported to Australia in 1935 to control the native grey-backed cane beetles that were harming sugarcane crops. With very few natural predators, their population began to grow rapidly. Experts estimate that there are currently over 200 million specimens spread across Northern Australia and the numbers are only growing....

While Spain's tomato-throwing festival, La Tomatina, that is celebrated in Bunol every summer is world-renowned, the country's other food-centric celebrations are not as well known. The Els Enfarinats and the Jarramplas festivals that are held in December and January respectively, also involve food fights, except the produce being tossed, is not as gentle as tomatoes....

When Pluto was demoted to dwarf status in 2006 we were left with a mere eight planets in our solar system. Now Planetary Astronomy Professor Mike Brown, the researcher responsible for 'killing' Pluto may have redeemed himself with the discovery of a massive ninth planet - One he believes is worthy of being added to the elite group of eight....

Being famous for having one of the most bitter winters in China and most likely the world does not sound like a good way to market a city. However, it works for Harbin.

On December 30, the International Union of Pure and Applied Chemistry announced that elements 113, 115, 117 and 118 are now approved to join the prestigious periodic table. Their addition completes the group of man-made elements that make up the table's 7th row, and brings the total number that will need to be memorized by students to 118!...

Food waste is a growing problem both in the United States and across the globe. In North America alone anywhere from 30-40% of perfectly edible food ends up in the trash each year. To put it in perspective that is almost 20 pounds of food per person, per month! While the fact that most ends up in our landfills is bad enough, what's worse is that over 48 million Americans, including 15.3 million kids, live in households that do not have sufficient food! Now, concerned citizens are trying to raise awareness of the issue with some innovative ideas....

A few years ago, Douglas Long and his colleagues from the California Academy of Sciences were helping D. Ross Robertson identify some chimaeras caught off the Pacific coast of Central America in 2010. Among the images were those of a mysterious pitch black shark. Intrigued, the marine ichthyologist asked the Smithsonian Institute researcher to lend him the preserved specimens so that his team could study the fish in detail....

Access to clean water is something many of us take for granted. However, for millions of people living in developing nations, it is a scarce commodity. According to the World Health Organization 3.4 million people, mostly children, die annually from water-related diseases. But that could change soon thanks to 'Row-bot', a tiny autonomous robot that powers itself by eating harmful water microbes....

Manatees or sea cows as they are often called, are large, rotund marine animals that can weigh as much as 1,000 pounds. But despite their enormous size, the mostly herbivorous animals have no blubber to protect them from chilly winter waters. Hence, every winter, the gentle giants seek out warmer waters. For the approximately 6,000 Florida manatees that reside in the Gulf of Mexico it means heading to the balmy 72°F waters of the roughly one-acre Three Sisters Spring in Florida's Crystal River National Wildlife Refuge....

In November 1966, Fred Thrower, the President of New York-based television station WPIX was faced with a dilemma. He had to figure out some exciting Christmas Eve programming to replace a three-hour slot left vacant by the cancelation of the regular Saturday night college basketball game....

Two weeks ago, representatives from 196 countries arrived in Paris to resolve one of the world's most pressing problems — Climate change. On Saturday, December 12th, the group emerged victorious with the first-ever global accord in the fight against global warming — One that U.S. President Obama hailed as the "turning point for the world" and the "best chance to save the one planet we've got."...

Mention snakes and the image that comes to mind is that of a stealthily gliding reptile. Turns out that this was not always the case. Ancient snake fossils indicate that the reptiles once had legs, just like the rest of us. So why did snakes decide to shed them in favor of the slither that sends chills down our spines? That is a mystery researchers have been trying to solve for some time....

To say that David Richards loves to create Christmas light displays is an understatement. In the past four years, the Canberra resident has picked up three Guinness World Records - Two for 'most Christmas lights on a residential property' and one for 'largest image made of LED lights.' On November 27th, the Canberra resident broke yet another record - This time for 'most lights on an artificial Christmas tree.'...

At sundown on Sunday, December 6th, millions of Jews around the world celebrated the first day of Hanukkah by lighting a candle and singing traditional songs. The eight day festival that is observed annually, starts on the 25th day of Kislev, the ninth month of the Hebrew calendar, which follows the lunar cycle. Hence, its exact date varies anywhere from late November to the end of December....

While physics, chemistry, and biology are a norm at all schools, computer science is still a nascent subject. It is estimated that just 10 percent of American schools offer computer science and only 19% of high school students graduate with the course under their belt. Seattle-based non-profit Code.org wants to change that by exposing every student in the world to this all important science that is the basis of the digital world we live in....

Rising water temperatures and the increasing levels of carbon dioxide in our oceans are killing our beautiful coral reefs at an unprecedented rate. Add the current El Nino weather pattern that is expected to prevail through winter and spring 2016 to the mix, and things look even worse. Scientists estimate that the 1988 El Nino destroyed almost 16% of the world's coral reefs and believe things could get even worse this time around....

On October 7th, residents of the Chinese cities of Jiangxi and Foshan reported a strange sight - Towering skyscrapers that appeared to be dangling from the clouds. As the video of the 'floating city' went viral, it resulted in various theories. Some speculated the residents had seen a window to a parallel universe while others believed they had just glimpsed into a secret NASA project. Then there were the skeptics that dismissed the whole thing as a hoax. While that may still be the case, some experts believe that it could also have been a rare, naturally occurring optical illusion called Fata Morgana....

Space travel has come a long way since Russian cosmonaut Yuri Gagarin orbited Earth in 1961. However, the one thing that has eluded scientists thus far is a rocket that can be used multiple times. Though that may not sound like a big deal, it is for companies that want to make sub-orbital travel available to everyone. That's because a large proportion of the cost goes towards building the rocket which only flies once. It is therefore no wonder that Blue Origin's successful launch and landing of the world's first reusable rocket is causing such excitement....

Most people have a love-hate relationship with gum. For delicious as it is, the sticky, tasteless waste that remains is not just annoying, especially when inadvertently stepped upon, but also, harmful to the environment. That's because the primary ingredient in most modern chewing gums is synthetic rubber which is not biodegradable. With an estimated 560,000 tons of gum being chewed each year, this adds a lot of unwanted polymer to our already overwhelmed landfills. Now thanks to Gumdrop Ltd., there may be a solution to this sticky problem....

Since their formation in 2003, Anonymous, a loosely organized international group of hackers have conducted a series of well-orchestrated cyber attacks on corporations, governments, and individuals. Some of the crusades have been justified and necessary, while others have been viewed as vindictive. But few people have any reservations about their most recent undertaking - To bring down ISIS!...

Deserts are by definition barren areas of land with little precipitation. But few compare to Atacama Desert. Often called the world's driest non-polar desert, the 600-mile stretch of land gets an average of just 0.13 inches of rain annually, despite its location next to our planet's largest body of water, the Pacific Ocean....
