In June 2014 a ‘super-smart computer’ convinced human judges that it was a 13-year-old Ukrainian boy. It was said to be the first artificial intelligence to pass the Turing test, which determines if a computer can deceive a human into believing they are interacting with another human. However, many scientists accused Eugene’s makers of cheating the system by making him a young teenager and a non-native speaker of English.

The hyperloop is a new system of super speed ground-level transportation. The concept is described as a vacuum or low air pressure tube which would allow a hovering pod to travel at speeds as high as 1200 kilometers per hour. Low friction is key to these speeds as well as being energy efficient compared to regular high speed trains. Supporters claim travel times could be shorter, compared to planes, for distances of up to 1500 kilometers.

Art is often described as expression or application of human creativity and as a vehicle of communicating ideas and emotions. Art categories include literature, decorative arts, performing arts, music, and architecture. However, labelling and categorizing arts will almost certainly result in being reductive since art is being continually re-defined as new movements develop.

China is the third country after the United States and the former Soviet Union that successfully landed a spacecraft on Mars. The six-wheeled robot was targeting a terrain in the planet's northern hemisphere. The vehicle used a combination of a protective capsule, a parachute and a rocket platform to make the descent. Images submitted by the robot show a totally different landscape on the northern side of the Utopia Basin. The terrain looks flatter and has mostly fine-grained sediment.

BASE is an acronym which stands for Building, Antenna, Span and Earth. Unlike parachuting or sky diving, base jumpers do not use an aircraft but jump from these fixed objects like tall cliffs or bridges. They wear a parachute or a wingsuit to slow down the descent. Wingsuits allow for precise aerial maneuvers but also require training and experience. Although modern equipment has become safer and lighter base jumping is still considered an extremely dangerous sport.
