Now scientists have documented mass migrations over the Gulf of Mexico, identified the voices of migrants in the night sky, and showed how songbirds navigate using stars, polarized light, and magnetic fields. Miyoko Chu explores the intricacies underlying the ebb and flow of migration, the cycle of seasons, and the interconnectedness between distant places. Songbird Journeys pays homage to the wonder and beauty of songbirds while revealing the remarkable lives of migratory birds and the scientific quest to answer age-old questions about where songbirds go, how they get there, and what they do in the far-flung places they inhabit throughout the year.

    After 3.8 billion years humankind is about to start evolving by new rules...From leading geopolitical expert and technology futurist Jamie Metzl comes a groundbreaking exploration of the many ways genetic-engineering is shaking the core foundations of our lives -- sex, war, love, and death.At the dawn of the genetics revolution, our DNA is becoming as readable, writable, and hackable as our information technology. But as humanity starts retooling our own genetic code, the choices we make today will be the difference between realizing breathtaking advances in human well-being and descending into a dangerous and potentially deadly genetic arms race.Enter the laboratories where scientists are turning science fiction into reality. Look towards a future where our deepest beliefs, morals, religions, and politics are challenged like never before and the very essence of what it means to be human is at play. When we can engineer our future children, massively extend our lifespans, build life from scratch, and recreate the plant and animal world, should we?
