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....

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!...

Time and again we hear about alliances between animals that would ordinarily be prey and predator. But in most cases they are a result of a strategic decision made by zoo keepers trying to help one or both animals. However, that was not the intention of the workers at Russia's Safari Park when they allowed a goat into their resident Siberian tiger Amur's enclosure in November 2015. They were just serving him dinner! Hence, you can only imagine how surprised they were to find the goat alive and well the following day....

It is the beginning of a new year. This means that most of us have a lengthy list of goals laid out for the next 365 days. Facebook's founder Mark Zuckerberg is no exception. While his past resolutions have been mundane challenges like reading two books a month, meeting a new person every day of the year and mastering Mandarin, this year the Internet mogul has a loftier goal. He wants to build his own version of Tony Stark's (AKA Iron Man's) digital assistant and closest friend, Jarvis (Just A Rather Very Intelligent System)....

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....

With smart technology increasingly infiltrating all aspects of our lives it was only a matter of time before someone invented 'smart' shoes - Ones that can be customized at the owner's whim. Called ‘ShiftWear,' the animated sneakers are the brainchild of a team of entrepreneurs, futurists, and engineers led by New York-based designer David Coelho....
