NASA's Curiosity rover landed safely on Mars grounds: on the 5th of August, 10:31pm PDT, after 7 minutes of terror, the newest NASA's jewel safely landed on the Mars surface. The landing itself was already a big mission and a show of the finest engineering, as the delicate equipment inside the capsule approaching Mars needed to decelerate from 21,000 kph to 0 kph without crashing on the ground. This required different systems to make the landing safe, but everything went well and the rover already sent the first high-resolution pictures from the red planet. The mission is one of NASA's biggest on Mars, due to its size and the funds spent on it. Its aim is to determine whether Mars hosted life once (or still!). The mission will last 2 years, but the plutonium on board Curiosity can provide energy up to 14 years. Hopefully, it will serve as well as Spirit.
Virtual sensation comes closer: scientists at University of Illinois, Urbana-Champaign experimented a new device which could recreate virtual sensory touch using an electronic "fingertip". The device would consist of a silicon hollow tube to be placed around the fingers with a circuit inside which could provide electrical stimuli to the fingertips simulating sensation. These circuits were built only on flat surfaces, making impossible to give a full sensory experience. The new study is experimenting and opening the way to provide sensations such as temperature, pressure and texture. The potential applications are variate, the first being giving sensation back to people who have lost it due to burnt skin.
Triumph expression is universally recognized: having seen many, recently thanks to London 2012, a study suggest that the expression of olympic triumph is an expression which is universally recognized, next to anger and happiness. Psychologists noted that it is present in cultures which have nothing in common and are different on many grounds.
