Freestyle motocross maestro Robbie Maddison is well-known for his heart-stopping stunts. In 2008, the Australian daredevil wowed the world with a leap over the 164-feet tall Arc de Triomphe in Paris, France. In 2014, he performed several back flips over stationary airplanes at the military service aircraft graveyard in Tucson, Arizona. However, neither compare to his latest stunt - "Surfing" a wave on a slightly modified KTM dirt bike....

An agricultural experiment called Nemo's Garden is taking farming to a new level - about 20-feet below the ocean's surface!

Tossing food at total strangers is not something that is acceptable in most settings. However, at the La Tomatina festival in Bunol, Spain, it is not just accepted but encouraged.

In August 2013, Elon Musk, the CEO and CTO of SpaceX, the world's first privately funded spacecraft company unveiled a 57-page white paper that outlined a radical new supersonic transportation system. Called Hyperloop, it envisioned giving residents of high-traffic cities that lie within short distances the option to commute in enclosed capsules through low-pressure steel tubes at up to 800 mph.

Space food has come a long way since John Glenn orbited Earth in 1962. He and other members of Project Mercury, the first American human spaceflight program, had to endure unappetizing foods that came in the form of bite-sized cubes, freeze-dried powders, and semi-liquids stuffed in aluminum tubes. Today astronauts can select from an extensive menu of over 70 foods and 20 beverages. The one thing they still can't get? Fresh fruits and vegetables!...

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....

However, the most recent epidemic, the deadliest since the disease was identified in 1976, has brought the aggressively contagious viral illness to the forefront. Researchers from all over the world have been frantically trying to find a cure.
