Dear Readers, Welcome to a bonus issue of Science Focus. Perhaps this will remind you of the joy of science, when you are kept busy by study trips, revision, or homework, during your Easter holiday. We focus on biology and mathematics this time. Although most of us have uniform skin colors that change little, some animals are far better at changing theirs, at short notice. We explore the color-changing secrets of chameleon and octopus. For cat lovers, we discuss the physiology and genetics of cats through memes. We also delve into the science and ethics behind animal cloning. Have you ever watched the movie Good Will Hunting? We bring you an equally captivating Korean movie that is worth adding to your playlist. Finally, for those of you who are puzzled by various ways to tie shoelaces, you will find a mathematical guide in this issue. We have just launched this year’s “Science in Lyrics” Writing Competition. For details, please visit our website by scanning the QR code on the back cover.
