From a distance, the Casa del Acantilado (Cliff House) in Salobrena, Spain looks like something you would expect to encounter in "Game of Thrones" or "The Hobbit." However, come closer and you will realize that this three bedroom home that closely resembles a scaled dragon is an architectural wonder — One that has been designed to fully embrace its beautiful natural surroundings....

Every year more than 2 million people, a quarter of them children, end up in hospital emergency rooms with concussions — And those are the lucky ones! That's because there are millions more that postpone treatment or even worse, never get themselves examined simply because they don't experience the classic concussion symptoms that include vomiting, blurred vision, and loss of balance....

The fact that computers are getting increasingly smarter is evident. However, they still lack creativity and intuition and hence cannot learn, think and understand like humans — At least, that was the consensus until Google's AlphaGo computer algorithm beat 18-time world champion Lee Se-dol, 4 to 1 at the ancient Chinese game, Go....

For those that enjoy pranks, there is no better day than April 1. Also known as 'Fool's Day' it is the one day of the year when light-hearted tricks are not just accepted but welcomed! Nobody knows how this fun tradition started. Some think it began in 1582 when the world moved away from the Julian calendar, (that began the new year in April) to the current Gregorian calendar. Others think it was to celebrate the onset of spring....

Just when we think there couldn't possibly be any more mysteries left to solve about the human anatomy, comes another discovery. This one has to do with sighing. It turns out that the involuntary reflex that is generally associated with sadness or despair is crucial to our well-being. That is why researchers at the University of California, Los Angeles and Stanford University were determined to find out what triggers this spontaneous action, without which our lungs would collapse!...

They have their own rituals which may not include egg hunts and Easter bunnies, but are equally fun!...

On Thursday, March 24, the streets of India will be awash with color as residents celebrate the spring festival of Holi. The annual event that is the inspiration behind the 'color runs' in the US, is observed on the last full moon day of the lunar month, Phalguna (in the Hindu calendar). However, unlike the copycat runs, festival participants do not have to compete in five or ten-kilometer races to have fun. All they have to do is take to the streets early in the morning and chant "Holi Hai" (It's Holi) while dousing strangers and friends alike, with colored powder....

On January 17, Brigitte Barthélémy was walking along the seashore just north of France's famous Bordeaux wine region when she stumbled upon a bottle nestled among a pile of seashells. Inside were two tightly rolled pieces of paper. One contained a beautiful hand-drawn sketch of a cormorant, while the other was a message from the New York Pelagic outlining how litter caught in the ocean currents is often fatal for the water birds that mistake the bright plastic debris for food....

Once underground mines have served their purpose, most are sealed and forgotten. The 2000-year-old Salina Turda Salt Mine in the city of Turda, Romania was no exception.

On Saturday, March 19, millions of businesses and individuals worldwide will celebrate Earth Hour by turning off all lights and electronics from 8:30 - 9:30 PM local time. The voluntary rolling blackout that includes 350 of the world’s most iconic landmarks such as the Eiffel Tower, the Empire State Building, Taipei 101 and the Sydney Opera House, is more than a symbolic gesture — It is proof of what can be achieved if we all unite to reverse climate change....

This past weekend, millions of people in cities around the world participated in parades honoring St. Patrick, the primary patron saint of Ireland.

So who was the amazing priest whose death anniversary is celebrated worldwide and what led to the unusual traditions? Read on . . ....

The increase in the use of drones by consumers is becoming problematic for countries around the world. That's because enthusiasts often take advantage of the still nascent and in some cases nonexistent laws that govern quadcopters and use the unmanned vehicles for dangerous and illegal activities.

Though not rare, total solar eclipses are highly anticipated. That's because they are visible from a narrow corridor of the planet and last for just a few minutes. 2016's first and only total solar eclipse that took place on March 8 or 9 (depending on the time zone), was no exception. The celestial event could only be seen in totality by residents of the Indonesian Islands of Sumatra, Borneo, Sulawesi and Halmahera....

With no threat of predators or the need to hunt for food, shelter, or find a mate, zoo orangutans have an extremely comfortable existence. But this also means that the smart animals lack the critical challenges they need for their mental and emotional well-being. To ensure the curious mammals that share 97% of their DNA with humans do not get bored and depressed, zookeepers are always looking for new ways to keep them entertained and challenged....

Its mission was to circle the moon and thoroughly test the components and procedures to pave the way for the first lunar landing. The mission went flawlessly and without incident — At least that's what everyone believed....

Just like Harry Potter's invisibility cloak, Marty Mcfly's hoverboard, featured in "Back to the Future" Part II and III, has captured the imagination of both fans and scientists. But despite numerous claims, no one has been able to replicate the flying skateboard that bounced off walls and easily outpaced cars. Now thanks to US-based ARCA Space Corporation, hoverboards may finally become a reality....
