Limb Lengthening Surgery

Limb-lengthening surgeries are becoming more popular, despite the complications. The surgery begins with a doctor breaking the patient's shin bones and inserting a telescopic rod into them. As the bones heal over time, the rod pulls the bones apart gradually - approximately 1mm per day - and as the bone is stretched, new bone, nerves, arteries, as well as skin, grow to fill in the gap. After about 3-months time, patients can expect to add 2-3 inches to their overall height. Continue reading for a video of someone who spent $85,000 in limb-lengthening procedures alone.

Upwards Lightning

Upwards lightning is very rare natural phenomenon, with researchers estimating that less than 1% of lightning travels in an 'upwards' direction. This particular event was captured in Tropical Depression Dorian in Florida during August 2013. And, interestingly, of the three types of this phenomenon known to exist, all three were spotted in this one thunder cloud. According to Dr Ningyu Liu, upward electrical discharges transfer a large amount of electric charge into the upper atmosphere. Continue reading for the video and more information.

Camouflage Ocotopus

From afar, it's just a lifeless reef area, but once this diver gets closer, an octopus suddenly jumps into view as it deactivates its 'cloaking mechanism'. The footage you're about to see was captured by Jonathan Gordon in the Caribbean, and he says: "I dove down to have a look at the shell that you can see just under where the octopus appears and as I approached the octopus came out of hiding. I had literally no idea he was there until I was about a metre away." Continue reading to watch.

Real Goblin Shark

A father and son duo from Australia were fishing southeast of Green Cape off the coast of Victoria, and managed to catch an incredibly rare goblin shark, the only remaining member of the 125-million-year-old Mitsukurinidae family of sharks. Notable facial features include a long and flat snout that sits above a set of unusually long jaws filled with sharp nail-like teeth. Continue reading for a video and a full-body shot.

Real Time Traveler

Andrew Carlssin is allegedly a time traveler who was arrested in January 2003 for SEC violations for making 126 high-risk stock trades and being successful on every one. He supposedly started with an initial investment of $800 and ended with over $350-million, which drew the attention of the SEC. Later reports suggest that after his arrest, he submitted a four-hour confession wherein he claimed to be a time traveler from 200 years in the future. He offered to tell investigators such things as the whereabouts of Osama bin Laden and the cure for AIDS in return for a lesser punishment and to be allowed to return to his time craft, although he refused to tell investigators the location or workings of his craft. Continue reading for more bizarre cases of time travelers.

Skylon

The Skylon C2 is a new type of aircraft that uses the SABRE engine system, which relies on a device called the precooler - technology that cools down the air entering the engineer system by more than 1,000° C in a mere .01-seconds, resulting in an unheard-of cooling rate of 400 megawatts, enabling the plane to 'breathe' oxygen. SKYLON will also be able to take passengers into outer space, taking off and landing horizontally like a normal plane. SABRE will also be used in the LAPCAT A2.

Other Planets Sky

The Russian Federal Space Agency has just released a mind-boggling animation that shows how the planet's horizons will appear if other celestial bodies replaced the sun. The first star you'll see is Alpha Centauri, the nearest visible sun to our own, and one of the brightest in the southern night sky. Located 4.3 light-years away, nearly 300,000 times the distance from the Earth to the sun, a double-star system would appear in our skies if it replaced the sun. It orbits a common center of gravity every 80 years with its companion, Alpha Centauri B. Continue reading for the video and more information.

Self Replicating Machine

Yes, engineers have already devised an extremely simple machine that can make better versions of itself. To be more specific, Reaper on DamnInteresting.com says it's "a processor which can 're-carve' its communication pathways on-the-fly was given random arrangements and charged with executing a program that identified tones, and the most successful arrangements were combined over and over until a nearly 100% success rate was achieved." Continue reading for more fascinating facts.

Frozen Methane Bubbles

At first glance, it appears as if swarms of jellyfish are swimming around under an icy lake, but it's actually just thousands of frozen bubbles. That's right, these natural wonders, photographed across Banff National Park in Alberta, Canada, are made of highly flammable gas methane - emitted by bacteria after they consume dead organic matter. The video above shows just how flammable they are. Continue reading for more pictures and information.

Time Machine Simulator

Researchers at the University of Queensland in Australia have built a time machine simulator. In other words, this system can mimic how a quantum particle would behave if it passed through a closed time-like curve and interacted with a younger version of its self. They fired pairs of entangled light particles through a circuit, in which entangled particles are created from the same parent particle, so they are identical to each other and any force that acts on one immediately affects the other. Think of this as meeting the younger version of yourself right at the entrance to a time travel loop. Continue reading for a video and to hear what happened.
