Flowers are nature's ad men. They'll do anything to attract the attention of the pollinators that help them reproduce. That means spending precious energy on bright pigments, enticing fragrances and dazzling patterns.
Understanding how and why diversification occurs is important for understanding why there are so many species on Earth.

Eat your heart out Steven Spielberg — turns out artificial intelligence is not just a figment of your imagination. A team of researchers lead by Lulu Qian from the California Institute of Technology (Caltech) have for the first developed an artificial neural network — that is, the beginnings of a brain — out of DNA molecules.
