May 8, 2024Natural hazards are an unavoidable part of everyday life. In many cases, it’s the proverbial “it’s not if, but when” they might occur. Whether a wildfire threatens a local community or an earthquake devastates an entire region, the moment a hazard becomes a disaster there is a vital need for those impacted to have access to critical information. But where do you find timely, credible information? Well, the details of what has happened come from researchers and investigators, while the information people receive is shared by public information officers. Today’s speaker is both.
Steven Sobieszczyk is a scientist and spokesperson with the U.S. Geological Survey (USGS). While “Sobie” spent most of his career researching landslide hazards, sediment transport, and flooding, he now focuses on science communication and public information. Steve is a multihazard first responder and has spoken extensively about everything from earthquakes in Puerto Rico and eruptions in Hawaii to wildfires and floods across the U.S.
Join us for what should be a captivating evening of stories and insights into what it’s like to live a life where each day is one disaster after another. Special focus on the:
- Granite Pass Wildfire Complex
- Vicksburg Cemetery Landslide
- M6.4 Puerto Rico Earthquake
- 2022 Mauna Loa Eruption
Steven Sobieszczyk has spent 23 years with the USGS. Currently, he serves as media lead for natural hazards at the bureau. Between 2005 and 2010, Steve earned degrees in landslide engineering geology, hydrology, and geographic information systems (GIS) from Portland State University. Besides his research, Sobie’s passion is to help others communicate better, regardless of their background or interests. Never satisfied, Steve has developed broad expertise, including being a professor, author, videographer, and artist. He is a co-founder of the Association of Science Communicators (ASC) and spends part of the year as an incident first responder for wildfires and other natural disasters.

May 8, 2024The James Webb Space Telescope was launched on Dec. 25, 2021, and commissioning was completed in early July 2022. With its 6.5 m golden eye, and cameras and spectrometers covering 0.6 to 28 µm, Webb is already producing magnificent images and surprises about galaxies, active galactic nuclei, star-forming regions, and planets. It extends the scientific discoveries of the great Hubble, and ties the most distant galaxies to their origin story from the fluctuations of the cosmic microwave background radiation. Scientists are hunting for some of the first objects that formed after the Big Bang, the first black holes (primordial or formed in galaxies), and beginning to observe the growth of galaxies, the formation of stars and planetary systems, individual exoplanets through coronography and transit spectroscopy, and all objects in the Solar System from Mars on out. It could observe a 1 cm2 bumblebee at the Earth-Moon distance, in reflected sunlight and thermal emission. I will show how we built the Webb, why we study infrared, and the most exciting current discoveries. Webb is a joint project of NASA with the European and Canadian space agencies.

May 9, 2024Light-Responsive Materials for a Sustainable Future: Exploring Optically-Controlled Functional Organic Systems
Assistant Professor Grace Han - Department of Chemistry, Brandeis University
Host: Matt GolderLight-responsive materials hold immense potential in revolutionizing various fields including solar energy conversion and storage, recyclable catalysis, single-molecule sensing, and reversible nanomaterial assembly. These materials exhibit phase transitions, changes in solubility, and nanoscale mechanical alterations triggered by external stimuli, particularly light, through molecular-level structural changes. While the photo-switching of molecules has primarily been studied in dilute solutions, understanding this process in condensed liquid or solid environments is crucial for successful real-world applications. Currently, there is a lack of fundamental knowledge regarding the interaction between light and molecules in condensed phases, as well as the impact of photomechanical switching on intermolecular interactions.
This presentation aims to elucidate the design principles behind optically-controllable materials that integrate organic photoswitches or solid-state photochromes. Extensive exploration of various photochromic core structures and functional groups has been conducted to gain insights into the structure-property relationship of these stimuli-responsive material systems. Additionally, the talk will introduce the application of photo-controlled materials in solar photon and thermal energy storage as well as sustainable catalysis.

Seminar date: Monday, May 13, 2024 - 12:00 to 13:00
Location: Hitchcock Hall (HCK) 132; uw.edu/maps/?hck
Stable isotope analyses are powerful tools for reconstructing ancient ecologies and ecosystems, as they provide direct insights into dietary ecology independent of morphology. The application of stable isotope analyses, however, is not without limitations, as determination of food web dynamics using these methods often relies on poorly tested assumptions. In this presentation, I will address challenges in paleoecological reconstructions of South American tropical ecosystems. By testing long-standing assumptions of stable isotope analyses, I aim to validate the suitability of applying these techniques to different mammalian clades, and to more reliably interpret the isotopic signals preserved in extinct organisms.

May 14, 2024Steven Pinker: Rationality: What It Is, Why It Seems Scarce, Why It Matters
In the midst of humanity’s remarkable scientific progress, we find ourselves grappling with an alarming surge of misinformation, pseudo-science, and conspiracy theories. However, attributing this solely to human irrationality seems inadequate given our capacity for discovery and rational thought.
Psychologist Steven Pinker proposes that our cognitive processes, evolved for simpler contexts, often fail to utilize the sophisticated tools of reasoning available to us. Despite our advancements, we frequently overlook logic, critical thinking, and probability, hindering our ability to navigate complex modern challenges effectively. Moreover, individual pursuits of self-interest and group cohesion can collectively foster societal irrationality, underscoring the importance of fostering norms that prioritize objectivity and truth.
Rationality, Pinker argues, is indispensable — it guides our personal choices, shapes public discourse, and serves as a catalyst for social justice and moral progress.
Steven Pinker is the Johnstone Family Professor of Psychology at Harvard University. He specializes in visual cognition and developmental linguistics, and his experimental topics include mental imagery, shape recognition, visual attention, regularity and irregularity in language, the neural basis of words and grammar, and childhood language development.

Modeling Speech-To-Language Transformations in the Human Brain
Edmund Lalor, Ph.D., Associate Professor, Department of Neuroscience and Department of Biomedical Engineering, University of Rochester
To transform speech into words, the human brain must accommodate variability across utterances in intonation, speech rate, volume, accents and so on. A promising approach to explaining this process has been to model electroencephalogram (EEG) recordings of brain responses to speech. In this talk, I will describe our use of this approach over the past decade to understand how the human brain transforms speech to language and how this transformation is affected by attention and visual input.

It takes tremendous biological creativity to be a plant. To survive and thrive while rooted in a single spot, plants have adapted ingenious methods of survival. In recent years, scientists have learned about their ability to communicate, recognize their kin and behave socially, hear sounds, morph their bodies to blend into their surroundings, store useful memories that inform their life cycle, and trick animals into behaving to their benefit, to name just a few remarkable talents. The Light Eaters (Harper) is a deep immersion into the drama of green life and the complexity of this wild and awe-inspiring world that challenges our very understanding of agency, consciousness, and intelligence. In looking closely, we see that plants, rather than imitate human intelligence, have perhaps formed a parallel system. What is intelligent life if not a vine that grows leaves to blend into the shrub on which it climbs, a flower that shapes its bloom to fit exactly the beak of its pollinator, a pea seedling that can hear water flowing and make its way toward it? Atlantic staff writer Zoë Schlanger takes us across the globe, digging into her own memories and into the soil with the scientists who have spent their waking days studying these amazing entities up close.

May 16, 2024"Paleo-CO2 revisited — challenges, advances, and implications"
Campus location Johnson Hall (JHN) Campus room JHN 075 Accessibility Contact Summer Caton, sacaton@uw.edu Event Types Lectures/Seminars Keywords: Paleo-CO2, global carbon cycle, paleoclimates
Abstract: Paleo-CO2 reconstructions are integral to understanding the evolution of Earth system processes and their interactions given that atmospheric CO2 concentrations are intrinsically linked to planetary function. Furthermore, past periods of major climate change, within both greenhouse and icehouse states, provide unique insights into the response of land-atmosphere-ocean interactions to warming induced climate change, in particular for times of pCO2 comparable to those projected for our future. How well the past can inform the future, however, depends on how well paleo-CO2 estimates can be constrained. Although CO2 estimates exist for much of the past half-billion years (the Phanerozoic), proxies used to reconstruct paleo-CO2, differ in their assumptions and degree of understanding, and many existing paleo-CO2 estimates do not meet modern proxy theory.
In this talk, I will first address present-day CO2 in the context of the geologic past and what it suggests about our future, and then discuss approaches to and challenges of reconstructing paleo-CO2 concentrations. I will then introduce the CO2 Proxy Integration Project (CO2PIP) as a path forward to advance the science of paleo-CO2 reconstruction and to build next-generation CO2 record for the Phanerozoic. This will include approaches that the CO2PIP Consortium is taking to modernize published paleo-CO2 records so that they meet modern proxy theory criteria and the modeling tools that are being developed to provide quantitative, data-driven CO2 reconstructions. To illustrate the potential of high temporal-resolution and modernized paleo-CO2 records to advance our understanding of how Earth surface processes and ecosystems responded to changing atmospheric CO2 concentrations, I will share a couple of examples of our work reconstructing CO2-climate-ecosystem interactions and feedbacks during a time (late Paleozoic Ice Age) when CO2 fluctuated within the range of Quaternary levels to those projected by socio-economic emission scenarios of this century. This deep-time interval was defined by CO2-driven abrupt (hyperthermal-scale) warmings that led to major changes in environmental conditions in the oceans and on land. If time permits, I’ll wrap up by discussing how the typically long-term processes of carbon cycling studied to interpret paleo-CO2 changes can be accelerated in soils of natural and working lands as a promising new CO2 removal technology capable of sequestering CO2 from the atmosphere in volumes and at rates relevant to climate change.

https://www.powells.com/events-update
Throughout Oregon and Washington there are several hundred thousand family forest owners, in addition to millions of forest acres under the care of community forests, municipalities, and Indigenous tribes, all of whom manage trees for sustainable wood harvest as well as recreation, inspiration, and a range of cultural connections. Yet there hasn’t been a complete resource for Pacific Northwest forest stewards until now. In their comprehensive how-to, A Forest of Your Own: The Pacific Northwest Handbook of Ecological Forestry (Skipstone), authors Kirk Hanson and Seth Zuckerman explore all aspects of forest management — everything from how to evaluate a piece of land before you buy it through implementing long-term plans that may include establishing new stands of trees, harvesting mushrooms as well as wood, and protecting your forests far into the future through wildfire risk reduction, climate change adaptation, and conservation easements. Loaded with helpful tables and illustrations that address the pros and cons of various species and how to best care for wildlife and the land, A Forest of Your Own is a clear guide to the many rewards of ecological forestry.

Bayesian alternatives to null hypothesis significance testing
Henk Kiers, Ph.D., Professor in Statistics and data analysis, University of Groningen, The Netherlands
Jorge Tendeiro, Professor in Bayesian statistics and inference, Hiroshima University, JapanNull hypothesis significance testing (NHST) and its p-value are ubiquitous in scientific practice. However, misuse and misinterpretation of these crucial tools is well documented. Various suggestions to fix, or replace, NHST have been offered. In this talk we will discuss some options that fall under the Bayesian inferential framework. We will introduce null hypothesis Bayesian testing (NHBT) and its Bayes factor as the direct Bayesian analogues to NHST and the p-value, respectively. Important differences between the two approaches will be highlighted. Furthermore, we will emphasize that, just as NHST needs to be accompanied by effect size estimates, so does NHBT. We will recall a simple relation between Bayesian estimation of (posterior distributions of) effect sizes and NHBT, and its implications. This will lead to the realization that estimation can be seen as a workhorse for various alternative types of hypothesis testing. Indeed, by combining ideas by Kruschke (2018) and Wellek (2010) with Smiley, Glazier and Shoda’s (2023) framework for statistical inference, it will be shown how all methods in that framework can be dealt with in a Bayesian way.

Lava, Mudflows and Ash: Volcanoes in the Pacific NorthwestLava, Mudflows and Ash: Volcanoes in the Pacific Northwest
–
May 22, 2024The Cascades Range is home to many volcanoes, but how active and dangerous are they? What are the greatest hazards from volcanoes in the Pacific Northwest, who monitors them, and how?
At this Science on Tap, Jon Major explores volcanic processes associated with volcanic eruptions and their aftermath, provides insights on the greatest threats posed by the Cascades volcanoes, and reveals how our regional volcanoes are monitored and why. The great 1980 eruption of Mount St. Helens fundamentally changed how scientists viewed volcanic eruptions. The four decades since have seen significant advancements in our understanding of volcanic histories, processes, hazards, monitoring capabilities, and the role that scientists have in communicating with governmental agencies and the public.
Jon Major is the Scientist-in-Charge at the US Geological Survey Cascades Volcano Observatory in Vancouver, Washington. He has worked at volcanoes in Washington, Oregon, Alaska, El Salvador, Chile, and the Philippines. He has been working at Mount St. Helens since 1981, and has been with the Cascades Volcano Observatory since 1983.

May 23, 2024Campus location Johnson Hall (JHN) Campus room JHN 075 Accessibility Contact Summer Caton, sacaton@uw.edu Event Types Lectures/Seminars Description Keywords: astrobiology, exoplanets, habitability
Abstract: We expect that exoplanets in the habitable zone of their host stars will experience a large diversity of seasonal cycles, ranging from negligible to extreme. The consequences of both end-member scenarios for habitability and life are not well understood, but recent work suggests that extreme seasonality could increase biological productivity and amplify biosignature detectability through its impacts on ocean stratification. This talk will explore several dimensions of habitability, from the prospects for an independent origin of life to the likelihood of biospheric progression towards animal-grade complexity. This talk will also discuss how seasonality may affect the relationship between biosignature production and biosignature detectability with future telescopes such as the Habitable Worlds Observatory.

Abstract: About 75% of Antarctica is buttressed by floating ice shelves, which regulate the rate that grounded ice is lost to the ocean, where it contributes to sea-level rise. Since the 1990s, many ice shelves have thinned, and in some cases disintegrated. With projected future increases in atmospheric temperatures, models suggest that surface meltwater production will rise non-linearly, and as a result, ice shelves will become more vulnerable to surface meltwater-induced breakup events. Initially focusing on the George VI Ice Shelf, Antarctic Peninsula, I will first present field and satellite-based observations, which reveal insights into the role surface meltwater on ice-shelf dynamics such as flexure and fracture. Second, I will present results of our study which combined satellite microwave data and a sophisticated snow model to quantify Antarctic-wide ice-shelf surface meltwater volume over the last four decades.
