Hearing mechanisms in baleen whales (suborder Mysticeti) are essentially unknown but their vocalization frequencies overlap with low-frequency anthropogenic sound sources. Synthetic audiograms were generated for a fin whale by applying finite element modeling (FEM) tools to X-ray CT scans. We scanned the head of a small fin whale (Balaenoptera physalus) ...
Urban water infrastructure systems must meet future challenges in managing water quantity and quality in growing cities worldwide. Information and monitoring technologies will play an important role. Within engineering and planning fields, resilient systems typically support quick returns to normal operations following outages. Other conceptions of resilience from ecology, however, ...

Recent advances in reflective hard x-ray / soft gamma-ray optics and the prospects for future astrophysical missions Over the last forty years, reflective x-ray telescopes have enabled detailed observations of the 0.1-10 keV x-ray sky and dramatically improved our knowledge of astrophysical processes, cosmology and fundamental physics. Focusing optics overcome intrinsic limitations of other techniques (e.g., absorptive collimation), and their use above 10 keV should revolutionize our ...
Watershed Collaborations: Entanglements on common streamsIn the tradition of Barad and Haraway, I practice Science and Technology Studies (STS) "from the inside", drawing on my own natural science training to inform the theoretical frameworks I develop. My interdisciplinary outlook is grounded in training, publication, and research in hydrology, aquatic ecology, and fluvial geomorphology, as well as in ...
Online Arms RaceThere is an accelerating arms race going on in the online world. We have all extended our lives from the real world to the online world. However, our data and our privacy is being threatened by attackers in the online world. We have to fight online criminals and online hacktivists. ...

Building Community - Strengthening Marin on Earth DayOur final lecture of the 2015 series will start an important conversation exploring the intersection of environmental conservation, and social equity in Marin. Adhering to the principle; strength lies in diversity, we must empower all the voices of Marin to be heard. Minority and marginalized voices are critical strands in ...

Rob Blumenschine describes nearly 30 years of research at Olduvai Gorge that sheds light on the origin of the capabilities in the earliest stone-tool maker, Homo habilis. In habilis we see the emergence of brain sizes larger than those of apes and the distinctly un-primate-like behaviour of competing with large ...
