    DR. HEIDI CULLEN - SEEING CLIMATE, SEEING CHANGE: COMMUNICATING CLIMATE SCIENCE IN A CHANGING MEDIA LANDSCAPE The financial collapse of 2009 brought with it major changes in the economic, political, as well as media landscape. This talk will explore how these ongoing changes have affected the public’s perception of climate change as well as discuss the challenges and opportunities facing the United States as world leaders gather in Paris later this year for United Nations Climate Change Conference (COP-21). One of those challenges will require creating new models for science journalism and one of those opportunities may require a redefinition of what it means to be a scientist.

    Dr. Robert P. Kirshner Clowes Professor of Science, Harvard University The expanding universe was discovered at Mount Wilson almost 100 years ago. But there is something new! In the past 20 years, astronomers have found that cosmic expansion is speeding up, driven by a mysterious “dark energy” whose nature we do not understand. Dr. Kirshner, one of today”s preeminent astrophysicists, is the recipient of many prestigious awards, including the 2014 Breakthrough Prize in Fundamental Physics (sponsored by Google, among others), as well as the 2014 James Craig Watson Medal of the National Acad- emy of Sciences for “service to astronomy.” Partial funding for Carnegie Observatories' 2015 Astronomy Lecture Series was provided by The Kenneth T. and Eileen L.

    Dr. Matthew P. Scott President, Carnegie Institution for Science Carnegie Astronomy is also part of Carnegie Science and the study of all living species. From ancient single-celled organisms evolved multicellular animals whose immense numbers of specialized cell types—skin, muscle, nerve—allow division of labor. Each cell type forms in the right place, is suited to its task, and activates certain genes. Powerful cell-to-cell communication systems organize structured tissues such as lungs, limbs and brain. Dr. Scott will discuss half-billion-year-old genes that have been gradually modified to give rise to the vast diversity of animals.

    Dr. John Mulchaey Staff Scientist Carnegie Observatories The light we see with our eyes only tells a small part of the Universe's story. To get a complete picture of how the Universe works, astronomers must study objects over the full range of light, the electromagnetic spectrum. This includes gamma rays, X-rays, ultraviolet, visible, infrared, micro- waves and radio waves. Each type of light requires different instruments, and provides unique information about the source that emitted it. Dr. Mulchaey will explain how Carnegie astronomers and their colleagues are combining observations across the electromagnetic spectrum to help solve the mysteries of the Universe.

    Speaker: Dr. Matthew P. Scott Why do we look like our parents? We inherit particular versions of genes that shape our growth. For a long time these genes were unknown and it was suspected that each class of animals would have distinct “designer genes.” Explosive progress has identified hundreds of genes that work together to shape animal growth, sculpting their tissues and organs, even the instincts embedded in brains. Surprisingly, scientists have found that many designer genes have been highly conserved during evolution. Some genes play similar roles, like controlling heart or eye development, in diverse animals. Different animals use related genes for related purposes because their common ancestors did. Damage to the designer genes can lead to birth defects, cancer, and neurodegeneration, so exploring how body-shaping genes function leads to new types of medical diagnosis and treatment.

    Speaker: Noam Elkies In a musical canon – be it “Three Blind Mice” or the climax of a Bach fugue – a tune acts as its own harmony. Thinking about how canons work leads us to look at musical structure from points of view usually associated with science and mathematics rather than the arts. The lecture will be illustrated with diagrams as well as musical examples (including recordings, live performance and improvisation), and will require no technical background in either music or mathematics.

    Speaker: Paul Fuchs A remarkable set of molecular mechanisms converts sound waves into electrical signals and encodes frequency content within the inner ear. “Feedback” by tiny cellular amplifiers can cause the ear to produce sound, while the brain employs a unique mode of neuronal inhibition to partially deafen the ear. These and other observations have led to important insights into how we hear, how this process can go wrong, and what we hope to do about it.

Silk Institut d'Astrophysique, Université Pierre et Marie Curie Department of Physics and Astronomy, The Johns Hopkins University Beecroft Institute for Particle Astrophysics and Cosmology, University of Oxford Astronomers peer back into the past with the world's largest telescopes. They see billions of galaxies, and they find indications of evolution and youth. Before the first galaxies, more than ten billion years ago, there were the Dark Ages. And before then, the Big Bang. But there is much of the universe that we cannot probe. Dr. Silk will describe the universe that we see and give an astronomer's perspective on the universe that we cannot see. He will describe the past with some confidence, and will speculate about the future, as perceived by cosmologists.

    The Story of Earth: How Life and Rocks Co-Evolved

    Dr. Robert Hazen, Carnegie Institution for Science, Geophysical Laboratory The story of Earth is a 4.5-billion-year saga of dramatic transformations, driven by physical, chemical, and—based on a fascinating growing body of evidence—biological processes. The co-evolution of life and rocks, the new paradigm that frames this lecture, unfolds in an irreversible sequence of evolutionary stages. Each stage re-sculpted our planet's surface, each introduced new planetary processes and phenomena, and each inexorably paved the way for the next. This grand and intertwined tale of Earth's living and non-living spheres is only now coming into focus. Sequential changes of terrestrial planets and moons are best preserved in their rich mineralogical record. "Mineral evolution," the study of our planet's diversifying near-surface environment, began with a dozen different mineral species that formed in the cooling envelopes of exploding stars. Dust and gas from those stars clumped together to form our stellar nebula, the nebula formed the Sun and countless planetesimals, and alteration of planetesimals by water and heat resulted in the approximately 250 minerals found today in meteorites that fall to Earth. Following Earth's growth and separation into the core, mantle, and crust, mineral evolution progressed by a sequence of chemical and physical processes, which led to perhaps 1500 mineral species. According to some origin-of-life scenarios, a planet must evolve through at least some of these stages of chemical processing as a prerequisite for life. Once life emerged, mineralogy and biology co-evolved, as changes in the chemistry of oceans and atmosphere dramatically increased Earth's mineral diversity to the almost 5000 species known today.

    Dr. Andrea Ghez University of California, Los Angeles, Department of Physics and Astronomy Lurking at the center of our galaxy is its most massive object—a supermassive black hole. More than a quarter century ago, astronomers first imagined that galaxies such as our own Milky Way might harbor massive, though possibly dormant, central black holes. Definitive proof lay in assessing the distribution and motion of matter at the center of the galaxy. Based on 15 years of high- resolution imaging, Dr. Ghez’s team has moved the case for a supermassive black hole at the galactic center from a possibility to a certainty. Although the stars orbiting close to the black hole appear to be massive and young, their origins are difficult to explain. Understanding them may provide key insights into the black hole’s evolution.

    SPECIAL EVENT A presentation by author and Washington Post science writer Marc Kaufman, followed by a discussion with Carnegie planet-hunter Paul Butler. Recent discoveries have convinced many astronomers that our galaxy is home to billions of exoplanets and that other galaxies have hundreds of billions more. The search is now on for distant planets in "habitable zones," where water is sometimes liquid and the possibilities for life are greatest. With a scientific consensus forming that these potentially life-sustaining planets also number in the billions, the logic for the existence of extraterrestrial life grows stronger all the time.
