In this January 8, 2015 photo, a monk Kenmyo Muta bows at the condominium construction site and the gate of Sengakuji temple in Tokyo. The “47 ronin” samurai who inspired the long-loved saga of loyalty and honor eulogized in films, books and plays are fighting a new kind of battle in urban Japan. An apartment complex is going up next to the curved tile-roofed Sengakuji temple where the three-century-old graves of the ronin, or masterless samurai, lie. The banner reads: “We only hope to protect landscape of Sengakuji temple”. (Photo by Eugene Hoshiko/AP Photo)

All the people we meet, all the things we know, and all of our experiences shape our souls, forever marking our faces. This was probably the main idea of the performance piece created by Chinese artist Zhang Huan, in which his face was painted over by three calligraphers with the names of people he knew, personal stories, and random thoughts. Truly, it amazing just how much we can find out about a person just by looking at their face. Surely, not everyone has the ability to see into the soul of the person just by looking at their face, but those that do can easily see the person’s personality, their intelligence, and sometimes even get glimpse into their past. Though it sounds like magic to people who don’t have this ability, it is completely true. Somehow, our mind can pick up on the miniscule changes of the facial structure and figure out the dominant facial expressions of that person. (Photo by Zhang Huan)

Nepal has cleared more than 300 mountaineers to climb Mount Everest after they had to abandon last year's efforts when an ice avalanche killed 16 guides in the mountain's deadliest disaster, an official said on March 20. The three-month climbing season for Everest, the world's tallest mountain, begins in March. (Photo by Tashi Sherpa/AP Photo)

A humanoid robot named Kansei, meaning “sensibility” in Japanese, makes a facial expression depicting “happiness”, next to the word “Love” during a demonstration at a laboratory of Meiji University's Robot and Science Institute in Kawasaki, south of Tokyo in this June 4, 2007 file photo. Three-fourths of robot installations over the next decade are expected to be concentrated in four areas: transportation equipment, including the automotive sector; computer and electronic products; electrical equipment and machinery. Labor costs have climbed in countries such as China that have been popular for outsourcing production, while technological advances for robots allow them to be more flexible and perform more tasks.

Number 10. BELL H-13 SIOUX was a two-bladed, single engine, light helicopter built by Bell Helicopter. Westland Aircraft manufactured the Sioux under license for the British military as the Sioux AH.1 and HT. In 1947, the United States Air Force ordered the improved Bell Model 47A. Most were designated YR-13 and three winterized versions were designated YR-13A. The United States Army first ordered Bell 47s in 1948 under the designation H-13. These would later receive the name Sioux. The Bell-built H-13 B is seen airborne in this April 29, 1951 photo. The helicopter is equipped with a 173 horsepower engine, cruises at 85 miles per hour, climbs 900 feet in a minute and has a service ceiling of 11,500 feet. (Photo by AP Photo)
