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....

Need a computer but can't afford the high cost? Then you are in luck. That's because a team of brilliant engineers from Oakland-based Next Thing recently unveiled one that costs a mere $9! Called CHIP, the tiny machine is equipped with a fully-functional operating system that includes dozens of open-source applications such as pre-installed word processing, photo and audio editing, web access, and email....

Human-controlled robot "surgeons" have been assisting doctors in operating rooms since 2000. However, the Single Site "wristed needle driver" that was created by Intuitive Surgical takes robotic precision to a whole new level. That's because its flexible "wrist" allows the instrument tip to move up to 45 degrees in all directions, enabling doctors to operate on organs like the uterus, without making large incisions that result in unsightly scars....

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. But over the past few weeks, both have made headlines for the same reason - extreme weather. 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....

The Port of Astoria in Oregon is battling an unusual challenge - how to rid the area of the over 2,300 sea lions that have taken up residence on the piers, without harming them. That's because while the squabbling pinnipeds may be adorable to look at, they are a nuisance and extremely destructive, especially in such large numbers....

Lost Lake in Central Oregon is a mysterious natural wonder. During winter, it resembles any other large body of freshwater. However, as drier weather kicks in the water disappears, transforming the 85-acre 'lake' into a beautiful meadow. Turns out that there is a logical answer to this magical phenomenon - a tube or tunnel created by an ancient lava flow that drains out the water....

The Opah is a striking fish species that can grow as large as 7-feet in diameter and weigh over 100 pounds. Also referred to as moonfish, the giants that can be found in both temperate and tropical seas reside at depths of 150 to 1,300-feet where the waters can be extremely chilly. Scientists have often wondered how the fish can withstand the temperatures given that they lack typical deep sea dweller characteristics like a large heart. Now thanks to some curious California researchers that mystery has finally been solved - The Opah has warm-blood!...
