Earth day which is celebrate every April 22nd, should not be just an ordinary day. It should changed every people perspective about the earth. Earth is old and required more attention, while pollutions are like infection and making earth ill. Don’t you know that big cities contribute more pollution rather then villages?
Energy saving in cities [...]

Nanotechnology may hold the key to making spaceflight more practical. Advancements in materials to make lightweight solar sails and the cable for the space elevator could significantly cut the cost of reaching orbit and traveling in space, as well as dramatically reducing the amount of rocket fuel used. Also new materials, along with nanosensors and [...]
