While we know a lot about molecular processes, they can’t be observed directly, and scientists have to rely on simple, two-dimensional drawings to depict complex hypotheses. That is, they did until now. Janet Iwasa’s colorful and action-packed 3D animations bring scientific hypotheses to life, showing how we think molecules look, move and interact. Not only is molecular animation a powerful way to illustrate ideas and convey information to general audiences, it’s also a powerful tools for inspiring new research. However, 3D molecular animation using commercial software requires skill and time, so Iwasa has created a simpler 3D animation software tool for biologists, allowing researchers to intuitively and quickly model molecular hypotheses. In 2014, she launched the beta of her new free, open-source animation software, Molecular Flipbook, which allows biologists to create molecular animations of their own hypotheses in just 15 minutes.
