For this end-of-the-year How on Earth show, we look back to 2016 with clips from some of our features from the past year: selections from the Our Microbes, Ourselves series, research about Zika, gravitational waves, and carbon farming. Those are just a few of the topics we covered in 2016, which also included: electric cars, electric airplanes, renewable energy, climate change, using the microbiome as indicator of length of time after death, star gazing, pesticides, life on other planets, planets around other stars, stars in other galaxies, eggs, plant diversity, marine animal sex, wildfires, recent science graduates describing their thesis work, PTSD, light pollution, pollinators, lead in water supplies, Alzheimer’s research, the Rosetta mission, the New Horizons mission, missions to Mars – past, present, and future, sleep, cell phones, and more!

Interview with LIGO Scientist Dr. Matt Evans (6:22): The recent big news in physics was the announcement of the first direct detection of gravitational waves. The detection was made by the LIGO project, which stands for “Laser Interferometer Gravitational-Wave Observatory”. Reports have said that this is a confirmation of general relativity and a new way to view the universe. To help us understand that, and why this is such a significant achievement, we have on the phone Dr. Matthew Evans, an Assistant Professor of Physics at MIT. Dr. Evans is a member of the LIGO Scientific Collaboration and the chair of the Advanced Interferometer Configurations working group. His research focus is on gravitational wave detector instrumentation, and the fundamental sensitivity of gravitational wave detectors.
And here you can see the signal and hear the “chirp” of a graviational wave!
