Selection of Least Leaf Density of Brassica rapa in an Artificial Selection Experiment Abstract: We investigated Brassica rapa leaf density trait by conducting an negative artificial selection experiment. In our experiment‚ we planted two population of 98 Brassica rapa: one for negative selection treatment‚ and another for control treatment. After the plants grew up‚ we measured the leaf density of both treatments. We then randomly selected 10 parents in control treatment‚ and also selected 10

A Japanese engineer Eiji Nakatsu saw how a kingfisher dives into the water without splashing any water with the help of its narrow beak. He thus created the Shinkansen bullet train with the same design of a beak ‚ this reduced noise ‚ used less power and enabled higher speed. Tardigrades need water fro live‚ when outside water they cover their molecular mechanism with proteins ‚ DNA in a sugar‚ this gave inspiration to
