The human tendency to gravitate towards people that are similar to them starts early. In school-age children, the behavior called homophily, or "love of the same" often has to do with how others dress or act. Adults tend to form groups based on social stature, professions or personalities. Turns out that forming cliques and shutting out those that are "different" is not just a human trait. South Africa's Chacma or Cape baboons display similar tendencies as well!...

Concrete has been a significant contributor to the spread of civilization. From the Pantheon built by the Romans almost 2,000 years ago to our homes today, the concoction made from water, aggregate, and cement, is why our structures can withstand the harsh elements of nature. But this seemingly indestructible material does have an Achilles' heel - The micro-cracks that form as it dries....

The Wapichan or Wapishana tribe of Guyana is an isolated community of fewer than 6,000 people that live on the edge of the rainforest around South America's Rupununi Savannah, one of the world's largest open ranges of savannah lands. Located in Guyana between the Rupununi River and the Brazilian border, the 5,000 square mile area of pristine grasslands, swamplands, and rain-forested mountains has been the source of food and water for the tribe for centuries. Unfortunately, their means of subsistence is now being threatened by illegal logging and gold mining activities....

While e-books are on the rise, most people, especially young kids, still prefer printed versions that they can pore over for hours on end. Though that is an excellent habit, it also means cutting down precious trees. But what if the book could revert to its roots and transform back into a tree? Now thanks to a Brazilian children's book publisher, that is possible, at least for one book!...

Texas, the second most populous U.S. state and India's capital Delhi may lie in two different continents and over 8,300 miles apart.

The only difference is that while Texas is being inundated with torrential rains, Delhi has been experiencing a heat wave so severe that it is melting the roads....

Earlier this month, the officials of China's Hunan Province revealed what they believe will be a new "Wonder of the World" — the planet's longest and highest glass-bottom bridge. When complete, the 430 meter-long and 6 meter-wide structure will connect the two summits across the Zhangjiajie Grand Canyon. While the length is certainly impressive, it is the 400 m (1,312 ft) height that will have most visitors gripped by fear as they try to traverse across....

One of the first signs visitors encounter at most museums is, "Please do not touch the exhibits." However at the new "Hoy toca el Prado" (Come touch the Prado) exhibition at Madrid's Museo Nacional Del Prado, the officials don't just encourage the habit, they insist upon it. That's because this unique art display has been specially created to enable visually impaired patrons to experience the joy of the works of some of the world's most famous artists, just like non-disabled people can....

In the last 15 years, Yves Rossy has used his amazing jetpack wings to soar over the Grand Canyon, fly alongside an F-17 bomber and even circle Japan's Mt. Fuji. However, his latest flight in Dubai surpasses them all. That's because this time the adventurer joined forces with his protégé, 31-year-old skydiver and base jumper Vince Reffet, to do what no human has accomplished before - fly in formation!...

When researchers from the University of Manchester and Manchester Museum decided to take a peek inside some ancient Egyptian animal mummies using CT scans they expected to discover perfectly preserved remains. To their surprise, only one-third of the 800 specimens they examined actually contained complete skeletons. The rest housed partial animal remains, or even worse, just some mud, sticks, and eggshells....

Creating a "green" or carbon neutral fuel to replace gasoline has been the holy grail for scientists for many years. However, while there has been some progress with inventions like electric batteries and biofuel, most options are either too expensive or not commercially viable to compete effectively with the fossil fuel. Now automobile manufacturer Audi is stepping up to the challenge with diesel made from carbon dioxide and water....

If there were a prize for the best boss in the world, it would be awarded to Li Jinyuan, the Chairman of China's Tiens Group Company. For how else can you acknowledge a leader who celebrates the company's 20th anniversary by treating 6,400 employees to an all-expenses paid trip to France?...

How often have you walked out from your favorite store with a great sense of accomplishment for snagging an incredible pair of jeans or a gorgeous dress for next to "nothing?" However, would you feel as smug if you knew that the person who made it works in an unsafe environment and gets paid next to "nothing?" This was what the folks at advocacy group Fashion Revolution recently decided to put to test in Berlin, Germany....

Though there are numerous saltwater lakes around the world, none can compare to the Dead Sea. Located between Israel and Jordan in the Middle East, the water of this landlocked lake boasts salt levels almost ten times that of oceans. The unusual salinity can be attributed to the fact that there is no outlet for the minerals to leave, causing them to accumulate. The same is not true of the water level, which remains constant due an almost even inflow from the Jordan River and loss through evaporation....

On November 24th, 2014, Samantha Cristoforetti became the first Italian woman astronaut to enter outer space. On May 3rd, the 38-year-old made history again - this time for brewing the first cup of espresso at the International Space Station! Prior to this, astronauts were resigned to getting their caffeine rush from instant coffee slurped from a pouch through a straw....

Over the years, numerous animal and bird species have become extinct. However, it is rare for the entire world to witness one as it is happening. This could very well be the case with the northern white rhinos given that there are currently only five known specimens left. What's worse is that only one, a 42-year-old named Sudan is male! If he passes away without producing an offspring, the rhino sub-species will soon disappear....

Researchers recently reported the discovery of three new species of dragons in the Andean cloud forests of Ecuador and Peru. However, don't run for cover yet, for these are not fire-breathing beasts that kidnap fair maidens and battle knights in shining armor. Instead, they are just tiny wood lizards that are often referred to as 'miniature dragons' thanks to their close resemblance to the mythical creatures....

Over the past few years, researchers have come up with many innovative ways to use human kinetic energy - from powering soccer fields to playgrounds and classroom lights. Now some scientists want to take it to the next level with a new fabric that harnesses everyday motion to power personal devices!...

If you ever visit the city of Chengdu that lies southwest of China's Sichuan Province don't be surprised to see a cute backpack-carrying poodle strutting down the streets on its hind legs.

Since February 2015, students have not even had to learn cursive handwriting....
