Much of what we experience in our lives each day is entirely forgotten. So what leads our brains to store experiences in memory that help us navigate the world? Perhaps the most important signal is mistake-making. Formal schooling unfortunately conveys the message that becoming more skillful means making fewer mistakes, which is demonstrably untrue. Come and learn how mistakes lead to advantageous changes to our memories and are the key to learning.
Professor Bob Duke is a former studio musician and public school music teacher whose research at UT focuses on human learning and behavior. Along with Art Markman, he co-hosts the NPR program and podcast Two Guys on Your Head, produced by KUT Radio in Austin.
Time: 7:00 – 7:40 p.m.
The event will be streamed live through our Facebook and YouTube channels and will include a Q&A session. Additional information is available at www.hotsciencecooltalks.org.
DeFord Lecture | Dr. Rose CoryApril, 18 2024Time: 4:00 PM - 5:00 PMLocation: Boyd Auditorium (JGB 2.324) The Role of Iron in The Degradation of Dissolved Organic Carbon in the Arctic by Dr. Rose Cory, Department of Earth and Environmental Sciences, University of Michigan Abstract: Current estimates are that 5–15% of the tremendous pool of organic carbon stored in permafrost soils could be emitted as greenhouse gases by 2100 given the current trajectory of climate change, resulting in an additional one third degree Celsius of warming everywhere on Earth (i.e., Arctic amplification of climate change). However, the degree to which climate change will be amplified by greenhouse gases released from thawing permafrost is highly uncertain in large part due to insufficient understanding of the processes that degrade dissolved organic carbon (DOC) to carbon dioxide (CO2). Our work has shown that DOC degradation is tightly coupled to iron redox cycling in permafrost soils of the Arctic and in the surface waters draining these soils. For example, in waterlogged soils, redox reactions of iron produce reactive oxygen species (e.g., the hydroxyl radical) that oxidize DOC. On a landscape scale, the hydroxyl radical produced by iron redox cycling can oxidize as much DOC to CO2 as does microbial respiration of DOC in arctic surface waters. Upon export of dissolved iron and DOC from permafrost soils to sunlit surface waters, iron likely catalyzes the sunlight-driven (photochemical) oxidation of DOC to CO2. As a consequence, current estimates of additional global warming from the permafrost carbon feedback may be too low by ~ 14%. |
UTIG Seminar Series: Tanner Mills, UTIGApril, 19 2024Time: 10:30 AM - 11:30 AMLocation: PRC 196/ROC 1.603 Speaker: Tanner Mills, Postdoctoral Fellow, University of Texas Institute for Geophysics Host: Peter Flemings Title: Predicting greenhouse gas fluxes to the atmosphere from thawing permafrost Abstract: Arctic permafrost is thawing at rapid rates, which threatens to expose large stores of soil organic carbon to microbial degradation. As microbes utilize this carbon source, they produce greenhouse gasses (GHGs; CO2 and CH4) that can be emitted to the atmosphere and act as a positive feedback during future global temperature increases. While the permafrost carbon feedback has received much attention in the literature, little is known about the multiphase flow properties and the temperature dependence of microbial GHG production rates in thawing permafrost, both of which are essential for predicting GHG emissions from permafrost in the future. Flow experiments of synthetic and natural permafrost specimens under frozen conditions and incubations of permafrost samples are being performed to better understand the effective and relative permeabilities and GHG production rates of thawing permafrost soils. These data will be integral in providing new source terms for permafrost and global carbon models. |
Master\'s Thesis PresentationsApril, 19 2024Time: 2:00 PM - 5:00 PMLocation: JGB The Master of Science (MS) degree at the Jackson School of Geosciences is considered to be the professional degree for a career in the Geosciences. This degree is the foundation for students pursuing employment in the petroleum industry, environmental and hydrogeological fields, state and federal government agencies, and other related geoscience fields. Some students also use the MS degree as preparation for pursuing a Ph.D. The Energy & Earth Resources Interdisciplinary program provides the opportunity for students to prepare themselves in management, finance, economics, law and policy leading to analytical and leadership positions in resource-related fields. The private sector and government organizations face a growing need for professionals that can plan, evaluate, and manage complex resource projects, commonly international in scope, which often include partners with a variety of professional backgrounds. As requirements for these degrees, students must present a professional talk on Master\'s Thesis Presentations. |

UTIG Seminar Series: Cornelia Rasmussen, UTIGApril, 26 2024Time: 10:30 AM - 11:30 AMLocation: PRC 196/ROC 1.603 Speaker: Cornelia Rasmussen, Research Associate, University of Texas Institute for Geophysics Host: Krista Soderlund Title: The Emerging Field Of Position-Specific Isotope Analysis: Applications in chemical forensics, exobiology, geo- and environmental sciences Abstract: Complex organics can be found all over our solar system and within each living thing on our planet, be it as part of its physiology or as a contaminant. However, different processes can lead to the formation of chemical identical molecules. This makes answering a number of scientific questions challenging. One example is distinguishing between biotic and abiotic molecules, hence hindering life detection on early Earth but especially on other planetary bodies, such as on Mars, Titan, Enceladus and on meteorites where organics have been detected. Moreover, tracing molecules as they move through the environment can be demanding, yet is essential in studying the flow of organic molecules as well as correlating pollutants with their source. Novel tools to address these challenges are currently being developed. Especially, the emerging field of position-specific isotope analysis is beginning to grant access to the unique intramolecular carbon (13C/12C) isotope fingerprint preserved in complex molecules. This fingerprint can be applied in various scientific disciplines, ranging from forensics to exobiology, geo- and environmental sciences, including geo health. Nuclear magnetic resonance spectroscopy (NMR) has the potential to become a key player in this research area, as it allows the analysis of organics within complex mixtures, all without the need to fragment the molecule into single carbon units or the combustion of the molecule of interest. We have been developing several NMR tools that allow us to investigate the intramolecular carbon isotope distribution within various molecule classes and to test the central hypothesis that the position-specific carbon isotope distribution within complex organics depends on a molecule’s source and formation history. |
