Natural selection has been sculpturing living organisms for millions of years, enabling them to get adapted to an ever-changing environment. Gradually, certain traits are selected over others based on the advantage they confer to the population. Natural selection is not a random process and it relies on genetic variation. Random mutations serve as the substrate […]

Our satellite is a magnificent spectacle in the sky.

What is a radiation dosimeter? Why do we need one? To give you an interesting and short response I will remind you what the Japanese government officials offered to Fukushima evacuees after the 2011 nuclear disaster. Having failed to reach their original radiation decontamination target, the government proposed that evacuees could return to their homes […]

Climate change due to global warming is usually presented as the Nemesis of our civilization. Day by day, evidences supporting temperature and sea level raise are presented. Numerical models point that CO2 concentration will lead to a new climate not very human friendly in what can be taken as the fastest ever climate change. Still […]
