Few conservation behaviors have captured the public’s interest as much as recycling. But sorting your trash and placing it at the curb isn’t recycling . . . it’s just the start of a long and somewhat surprising journey for your empty milk cartons and back issues of Cat Fancy.  

• Where do those materials go once in the bin?
• How do they get sorted out? And where do they go from there?
• What about those rumors that recycling trucks just deliver materials to the landfill . . . or dump them in the ocean? 
• How can recycling even deliver environmental benefit, given all of the trucks and machinery involved?
• What’s the deal with plastic, anyway? 

You have questions, and we have answers! 

After pioneering recycling policy in the late 1980s, Oregon is now implementing the first “extended producer responsibility” law for packaging in the U.S. The Plastic Pollution and Recycling Modernization Act, adopted in 2021, was launched July 1, 2025 and is designed to provide residents and businesses a recycling system that can be trusted to deliver the environmental benefits that recycling has long promised. But even it has limited potential to stem the tide of unsustainable levels of production and consumption.

Explore how recycling is simultaneously necessary and insufficient, how recycling needs to be improved, and what else Oregon could be doing to use materials sustainably. 

David Allaway and Justin Gast work at the OR Department of Environmental Quality, and between them have over 57 years of experience with recycling systems. In addition to his time at DEQ, Justin has worked at the local and national levels for the likes of Resource Recycling magazine, the Washington County (OR) Solid Waste & Recycling Program and The Recycling Partnership. David has testified before Congress and co-chaired Oregon’s Recycling Steering Committee, and his work has been featured in Last Week Tonight with John Oliver, the National Law Review, Time, Sierra and PBS Frontline.  

Have you ever looked through a foggy window and wondered what if that were your eyesight? What happens when the window of your eye becomes cloudy?

The cornea—the clear front surface of the eye—plays a critical role in focusing light and allowing us to see the world sharply. But infections, injuries, genetic conditions, and aging can damage this delicate tissue, leading to blurred vision, pain, and sometimes even blindness. The remarkable news is that many of these conditions are treatable—and in some cases, surgeons can replace the damaged “window” of the eye to restore sight.

Whether you have a corneal disease, know someone with vision problems, or are simply curious about how modern medicine can bring sight back, join us to learn about: 

• How the cornea works
• What cause it to become cloudy or scarred
• How treatments work
• How donated tissue can restore sight

Gain a deeper understanding of how damage to this tiny, transparent tissue is among the top causes of global blindness and how advances in eye care are helping people see the world clearly again.

Afshan Nanji, MD, MPH is an Associate Professor of Ophthalmology at the Casey Eye Institute at Oregon Health & Science University. She cares for patients with diseases of the cornea including infections, keratoconus, dystrophies, ocular surface cancers, and other conditions. In addition to her clinical work, she teaches future eye surgeons and conducts research to improve diagnosis and treatments for corneal disease.

Every winter, the amphibians of northwest Portland enter a real-life game of Frogger. Most drivers on U.S. Route 30 never notice the small, slimy critters leaping across the asphalt on rainy nights. But for northern red-legged frogs, the stakes are high—reach the water to lay their eggs, or die trying.

In response to their plight, biologists are using innovative solutions to help frogs and other vulnerable wildlife cross roads. With the help of buckets and bulldozers, over a decade of conservation efforts have inspired a growing community of amphibian enthusiasts in Portland. In the summer of 2024, they broke ground on their biggest venture yet: a tunnel for frogs beneath Route 30. 

Less than two years later, the project is shaping up to be an early success story. Along the way, scientists are using specialized technology to document northern red-legged frog behavior and develop strategies to protect this common, yet cryptic species. 

Join us to learn about the challenges our amphibian neighbors face and how we can help overcome them, while gaining a glimpse into the fascinating lives of frogs.

Menopause is becoming a buzzword! How do we separate the science from sensationalism?

Find out in this fascinating tour through the world of hormone fluctuations, ovarian aging, and medical interventions. We’ll cover: 

• Perimenopause vs menopause
• The impacts of menopause vs the effects of getting older
• Why hormone therapy went from favored to feared overnight, and what we’ve learned since
• How menopause affects our risks for chronic diseases
• Hormones: good for long-term health? Some safer than others? 
• What non-hormonal therapies are there?

There is no animal we’re more aware of having as neighbors as the American Crow. Loud, ubiquitous, and immediately recognizable, most Portlanders will see crows every day. And yet, there are few animals as mysterious and captivating. 

• If I feed crows, will they bring me shiny presents?
• Why are crows so intelligent, and what do they do with those big brains?
• Why, if we look outside at dawn and dusk, do we see vast numbers of them all flying in the same direction?
• Why do they tear out the grass in our lawns?
• Why do they bring bits of food and wash it in our bird baths?
• Why do they dive bomb some people?
• Do they really remember human faces? And hold funerals for their fallen? 

In this wide-ranging exploration of the exceedingly common, and unique, American Crow, we’ll learn what makes them so fascinating and mysterious, and try to answer some of these questions along the way.

As the climate emergency worsens and biodiversity shrinks, we humans get used to it—we adapt, we normalize, we forget. Scientists call this “shifting baseline syndrome” and warn that it’s why we are increasingly sleepwalking toward disaster.

In this positive and inspiring manifesto, the environmental activist and longtime editor-in-chief of Sierra magazine Jason Dove Mark offers an antidote, focusing on four simple but powerful rules that everyone can use to resist environmental amnesia: 

Go outside. Bear witness. Make a record. Pass it on. 

Mark makes the case for easy, everyday practices that can help us “remember the Earth” and support environmental conservation, restoration, and rewilding. And he shares moving examples of citizen scientists, birdwatchers, mountain climbers, and fishermen across the country who are putting them into practice. The Earth Said Remember Me: How to Revive Our Memories and Restore the Planet is a hopeful, achievable prescription for protecting the planet, one citizen at a time.

Jason Dove Mark has served as editor-in-chief of Sierra and editor of Earth Island Journal. His writing has appeared in the New York Times, Los Angeles Times, San Francisco Chronicle, and the Atlantic. He lives in the Pacific Northwest.

In the 1960s, biologists introduced wolves to Coronation Island in Alaska after deer overran it and decimated the forest understory. The wolves ate all the deer and, with nothing left to eat, starved. About 50 years later, the wolves of Pleasant Island Alaska found themselves in a similar situation: living on an island in the Pacific with no deer left to eat. The wolves of Pleasant Island, however, have not died out. Instead, they’ve broadened their palate to include sea otters. 

What scientists don’t know is how widespread this surf-and-turf phenomenon is. How does the complex web of wolf, deer, sea otter, hundreds of islands and a massive logging industry interact?

In 2024, a rescued border collie named Barley joined the investigation. Employed with K9 Conservationists, Barley is a professional scat detection dog with three field seasons under his belt. With the “understudy” dogs Tooma, Niffler, and Skipper, they have located over 1,500 wolf scats across 25 islands. Back at OSU, Kayla Fratt works to extract the DNA of the wolves and their prey from the fecal samples. She then uses cutting-edge genetic techniques, lasers shot from airplanes, and an awful lot of math to tell the story of the Tongass National Forest through the bum of a wolf. 

Bonus ending: This talk will conclude with a live demonstration from one of Kayla’s trained conservation detection dogs in the theater!!

Kayla Fratt is a PhD student at Oregon State University and a co-founder of K9 Conservationists. She has dedicated her life to training rescue dogs to help conservation biologists. Her research in Alaska is funded by the Alaska Department of Fish and Game and her PhD studies are funded in part by the National Science Foundation. 

Humans are inherently social, and for many, romantic love represents the pinnacle of emotional connection. Yet, not everyone finds a romantic partner or experiences the kind of connection they seek. Some may turn to AI for solutions.

From virtual companions to AI-driven therapists, artificial intelligence is already reshaping how we communicate, alleviate loneliness, and express desire. And as AI continues to evolve, it could become more than just a tool in our lives: it could become a romantic partner.

Dr. L. Kris Gowen will delve into the science of love, belonging, and happiness to explore whether AI mitigates loneliness or exacerbates it. Using what we already know about the intersections of emotional connection and technology, she will reflect on whether humans can truly fall in love with an AI, and can an AI reciprocate? What might a human-AI romance look like, and what could it mean for the future of intimate relationships?

L. Kris Gowen is a queer sexuality educator who has spoken nationally and internationally on the intersections of sex and technology. She has authored textbooks, teacher guides, and lesson plans to support inclusive school-based sexuality education, based in science and curiosity.

Extreme conditions are rare in the Pacific Northwest, but when the forecast hints at chaos, a small but dedicated group of storm chasers and weather geeks across the northwest spring into action, ready to capture the extraordinary.

Join us as we explore the most extreme weather that the Pacific Northwest has to offer through the lens of meteorologist and storm chaser Garret Hartung, including strong southerly windstorms, atmospheric rivers, cold core tornadoes, thunderstorms, floods, heavy snow, freezing rain, and extreme east wind events.

• What makes these events unique to the PNW?
• Why do we often miss out on some of the more extreme weather events seen elsewhere in the US?
• What makes storm chasing here so particularly difficult?   

Garret Hartung is a Senior Meteorologist at Portland General Electric with more than five years of experience forecasting weather in the PNW. An avid storm chaser since 2016, he has pursued and documented extreme weather and other natural phenomena across much of the Central and Western US. He is also a proud graduate of OSU where he earned a B.S. in Earth Sciences with a focus on climate science and meteorology. 

Volcanic eruptions can perturb global climate, build mountains, and reshape human civilizations. They can be deadly, but the deep roots of volcanoes also provide a foundry for critical minerals that enable modern society. In these ways and others, volcanoes have inspired scientists and artists alike for thousands of years.

The Volcano Listening Project explores connections between scientific research and artistic perspectives of volcanoes, developing tools to represent data through sound that draw equally from data science, volcanology, and new music.

Data ‘sonification’, the display of data using sound, is a powerful way to interact with and understand the complex signals recorded at volcanoes. By leveraging our ears as scientific sensors, it is possible to detect patterns and subtle signatures of deep, poorly understood, volcanic processes. In equal part, sonification of data can trigger an emotional response, and thus lead to compelling music.

This program will showcase the Earth songs of volcano music and explain the science behind it, led by volcanologist and violinist Leif Karlstrom. Joining Leif is an ensemble of internationally recognized musicians:

• Todd Sickafoose (Grammy award-winning composer and bass player for Ani DiFranco),
• Idit Shner (University of Oregon saxophone professor),
• Adam Roskiewicz (Grammy nominated with The Modern Mandolin Quartet, as well as work with the Ger Mandolin Orchestra and bluegrass band Front Country), and
• Johnny Rodgers (tuned glass virtuoso). 

Leif Karlstrom is an associate professor of Earth Sciences at the University of Oregon. He studies fluid motions in and on volcanoes, glaciers, landscape evolution, and geodynamics. He currently co-leads the Federal Advisory Committee to the U.S. Geological Survey National Volcano Early Warning System, and is also a violinist and composer, with recent national touring and recording credits including folk/bluegrass ensembles Front Country, The Lowest Pair, and Hot Buttered Rum.   

Nine frequently asked questions related to alcohol and brain function, with an emphasis on adolescents-young adulthood. 

Why is 21 years the legal age to purchase alcohol?
Why does alcohol give you the spins?
Does alcohol truly relieve stress?
Do teenagers get hangovers?
What does alcohol do to sleep?
Are there long-term effects of adolescent drinking?
What’s wrong with drinking games?
How does alcohol cause memory impairments
Can drinking on an empty stomach increase intoxication?

Many lores and misrepresentations about beverage alcohol (ethanol) abound and are retold throughout human history. Decades of scientific studies on alcohol effects on brain and behavior, however, are just as intriguing. From myths to data, this talk will explore the complicated relationships humans have with alcohol.

Dr. Kathy Grant is Professor and Chief of Neuroscience at OHSU. She is a behavioral neuroscientist and studies mechanisms of stress-alcohol outcomes and risk factors such as genetics, adolescent vulnerability, sex differences and decision-making in chronic heavy drinking.

Dr. Aqilah McCane is an Assistant Professor in the Division of Neuroscience at OHSU. She is an expert in neural mechanisms of adolescent decision-making and studies the developmental consequences of adolescent alcohol use on neural circuitry as well as adolescent risk factors for alcohol misuse in adulthood.

Join us for an interview (now a full-on tradition) with the friend-of-Science-on-Tap Mary Roach about her latest book!

The body is the most complex machine in the world, and the only one for which you cannot get a replacement part from the manufacturer. For centuries, medicine has reached for what’s available—sculpting noses from brass, borrowing skin from frogs and hearts from pigs, crafting eye parts from jet canopies, and breasts from petroleum by-products.

In Replaceable You, Mary Roach sets sail on the uncharted waters of regenerative medicine, exploring the remarkable advances and difficult questions prompted by the human body’s failings. When and how does a person decide they’d be better off with a prosthetic than their existing limb? Is there a sensitive way to harvest tissue and bones from the deceased? Which animals might be the best organ donors? Through interviews with patients, physicians, pathologists, engineers, and scientists, Roach immerses readers in the wondrous, improbable, and surreal quest to build a new you.

Mary Roach is the author of the New York Times bestsellers STIFF, SPOOK, BONK, GULP, GRUNT, and PACKING FOR MARS. Mary has written for National Geographic, Wired, and The New York Times Magazine, among others, and her TED talk made the TED 20 Most Watched list. She has been a guest editor for Best American Science and Nature Writing and a finalist for the Royal Society’s Winton Prize.

Cannabis has been used since antiquity to ease illness, increase sex drive, and highlight the pleasures of life. Pair that with the increasing availability of legal cannabis products in the US and it is no surprise that many people are exposed to cannabis throughout their lives.  In spite of this exposure from preconception through menopause, the long-term effects of cannabis are not widely understood. 

Join us to discuss what we know, and what we still need to know, about the effects of cannabis on: 

• Sexual health and function 
• Reproductive health and fertility 
• Pregnancy and offspring  
• Menopausal symptoms

The astonishing story of how animals use medicine and what it can teach us about healing ourselves.

Ages before the dawn of modern medicine, wild animals were harnessing the power of nature’s pharmacy to heal themselves. Animals of all kinds—from ants to apes, from bees to bears, and from cats to caterpillars—use various forms of medicine to treat their own ailments and those of their relatives.

Meet apes that swallow leaves to dislodge worms, sparrows that use cigarette butts to repel parasites, and bees that incorporate sticky resin into their hives to combat pathogens. De Roode asks whether these astonishing behaviors are learned or innate and explains why, now more than ever, we need to apply the lessons from medicating animals—it can pave the way for healthier livestock, more sustainable habitats for wild pollinators, and a host of other benefits.

Doctors by Nature explores how scientists are turning to the medical knowledge of the animal kingdom to improve agriculture, create better lives for our pets, and develop new pharmaceutical drugs.

Jaap de Roode received his MSc in Population Biology from Wageningen University in the Netherlands and his PhD in Evolutionary Biology from the University of Edinburgh in Scotland. He is interested in the ecology and evolution of infectious diseases, and currently studies infectious diseases of monarch butterflies, honey bees and humans.

Have you ever noticed a tree not fall over?  A tree’s natural state is upright—it’s their default mode. Yet, myths pervade:

• “You should thin your tree”
• “You should top your tree”
• “Douglas-firs have shallow roots”
• “Lone trees are more likely to fall”
• “The roots will ruin my foundation”
• “That tree will fall and kill my whole family”

Despite the ubiquity of normal, upright trees around us, we often only notice those scattered few that stop being upright, most often in extreme weather.  And frankly, those few sully the good reputation of the thousands of others.

In the Pacific Northwest, our trees grow to be some of the tallest and largest organisms on the planet, and that can be understandably intimidating as you watch them bend and sway during winter weather from your home.  Luckily, our trees did not achieve their prominence by accident, and this talk will explain what the trees are doing, how they react to their environment, and what you can do to make sure your trees are safe.

How does a tree build itself?  How does it choose which direction to grow?  Is it a giant, static monolith waiting to crush everything beneath it? or a dynamic, self-optimizing living system that wants to keep itself upright arguably more than you? Join us on a journey through the lifecycle of a tree: how it grows, lives, and dies.  In other words: how do trees become trees and what makes them so good at it?

So much data. So much misrepresentation. In our era, understanding the nuances of effective visual storytelling is more crucial than ever.

What is the neuroscience of vision?
The psychology of perception?
How do our brains process visual information?

Well-designed graphs can illuminate complex data, making it accessible and engaging for all audiences, while poor design choices, including misleading logos, can distort the truth behind the numbers.

Sip on local brews and learn about the aesthetic elements of data visualization AND the ethical responsibilities that come with presenting information. How can we ensure our visuals tell an honest story? What are the implications of data manipulation in public discourse? How to think critically about the visuals you encounter and create, highlighting the ethical dimensions in the context of neuroscience and psychology.

Science, design, and ethics—perfectly paired with a pint!

Jackie Wirz, PhD, (our own MC!) is a biochemist by training, a nonprofit executive by profession, and a teller of stories. After 15 years of bad graphics as a research scientist, she decided to educate herself on what actually goes into a great visualization. She leveraged these skills as a data management specialist, academic administrator, and as a nonprofit executive. In her spare time she is the MC (mistress of ceremonies) for a variety of events including Science on Tap!

Dr. Steven Bedrick is an Associate Professor at OHSU where his research focuses on the intersection of natural language processing and healthcare. He is also interested in the societal and ethical implications that arise from speech and language technology.

This is a repeat of a show at Kiggins Theatre January 2024.

The summer of 2024 marked the largest dam removal in world history. Four dams were removed from the Klamath River, which runs through Oregon and California. Dam removal was caused in large part by the push from tribes local to the area.

Come have a discussion with Civil Water Resource/ Restoration Engineer Brook M Thompson from the Yurok and Karuk Tribes, who has been involved in dam removal advocacy since she was seven years old. She’ll cover:

• How does one remove a dam? And what was so bad about the dam anyway?
• How does traditional ecological knowledge benefit restoration efforts?
• What can we expect now the dams are removed? What is next for bringing back the salmon population?
• Why are interdisciplinary fields required for successful restoration projects?
• What research is currently being conducted on the Klamath River post-dam removal?
• How you can build a connection with the local native community and support local restoration efforts.  

Brook M Thompson is from the Yurok & Karuk tribes of California and grew up on her ancestral river, the Klamath. The deaths there of tens of thousands of salmon encouraged her to become a water rights activist and a water resource/restoration engineer. She is currently pursuing a Ph.D. in Environmental Studies at UC Santa Cruz, researching Klamath salmon, restoration cooperation with tribes, and water policy. She has an M.S. in Environmental Engineering from Stanford and a B.S. in Civil Engineering from PSU.

Babies sleep more per day during the first two years than any other point in life. Scientists agree that this is a period of rapid change in the brain and body – but the mystery remains, what function does sleep serve us so early in life?

One idea is that sleep is an opportunity for our brains to practice, and process — especially critical early in life, when we are experiencing so many new things in the world around us. The brain controls how we connect with each other, and form relationships with our peers and loved ones. Healthy physical connections with others, including a foundation called “social touch”, is formed early in life and requires proper sleep to fully develop.

Studies have found an association between poor sleep early in life and neurodevelopmental disorders characterized by differences in social connection. This talk will expand on this lingering mystery by exploring:

• How does the function of sleep change with age?
• How a unique rodent – the prairie vole – can teach us how sleep and snuggles help our brains develop the foundation of social touch.

Noah Milman is a graduate student in the Department of Behavioral Neuroscience at OHSU. Previously, he contributed to the first-in-human clinical trial of 40Hz sensory stimulation for Alzheimer’s Disease. Now, he is interested in how early-life sleep and environment impact the sensory brain and our social connections later in life.

One of humanity’s oldest beliefs is that our world is alive. Though once ridiculed by some scientists, the idea of Earth as a vast, interconnected living system has gained acceptance in recent decades. We, and all living things, are more than inhabitants of Earth—we are Earth, an outgrowth of its structure and an engine of its evolution.

Acclaimed science writer Ferris Jabr reveals a radical new vision of Earth where lush forests spew water, pollen, and bacteria to summon rain; giant animals engineer the very landscapes they roam; microbes chew rock to shape continents; and microscopic plankton, some as glittering as carved jewels, remake the air and sea.

Humans are one of the most extreme examples of life transforming Earth. We have altered more layers of the planet in less time than any other species, pushing Earth into a crisis. But we are also uniquely able to understand and protect the planet’s wondrous ecology and self-stabilizing processes. Jabr introduces us to a diverse cast of fascinating people who have devoted themselves to this vital work.

Ferris Jabr is a contributing writer for The New York Times Magazine. He has also written for The New Yorker, Harper’s, The Atlantic, National Geographic, and Scientific American. He is the recipient of a Whiting Foundation Creative Nonfiction Grant and fellowships from UC Berkeley and MIT. Jabr lives in Portland, Oregon, with his husband, Ryan, their dog, Jack, and more plants than they can count.

A moth, a flea, a mosquito…
Insects are seldom mentioned in history texts, yet they significantly shaped human history. For example:

• Silkworms (moths) have been farmed to produce silk for millennia, and the Silk Road created a history of empires and cultural exchanges of ideas, philosophies, and religions.
• Fleas and lice carried bacteria that caused three major plague pandemics. Bacteria carried by insects left their ancient clues as DNA embedded in victims’ teeth.
• Lice caused outbreaks of typhus, especially in crowded conditions such as prisons and concentration camps. Typhus aggravated the effects of the Irish potato famine, and Irish refugees took typhus to North America.
• Mosquito-borne yellow fever was transported to the Americas via the trans-Atlantic slave trade, causing panic in the US and creating hazards in constructing the Panama Canal.

Dr. Rob Wiedenmann will explore the impact and common threads connecting these insects. This talk is based on his book, coauthored by J. Ray Fisher: The Silken Thread: Five Insects and Their Impacts on Human History.

Dr. Rob Wiedenmann is Professor Emeritus of Entomology at the University of Arkansas. He received a B.S. in Ecology and Evolutionary Biology, and a Ph.D. in Entomology, both from Purdue University. He also worked at the Illinois Natural History Survey, where he focused on biological control of insects and weeds.  He is a past-president of the Entomological Society of America.

Many ecological restoration projects are one-size-fits-all: kill the weeds, then plant native seeds. But across the West, native plants have unexpectedly reestablished themselves via wind, water, or underground seed banks at restored properties in Oregon, Washington, Idaho, and California within various ecosystems—prairies, estuaries, sagebrush steppe, wetlands and coastal sand dunes.

Scientists, in particular Indigenous scientists, have found that native seeds can regerminate after decades of dormancy underground and that some species—even federally endangered ones—will regrow once invasive plants are removed or water is returned.

This approach, known as “natural regeneration,” is understudied and overlooked by Western scientists. Yet Indigenous-led projects show that it is a more effective and more affordable way to restore degraded lands. This show will discuss a handful of tribally led restoration projects where native plants have returned on their own.

Humans unconsciously filter experience based on what they already believe (called confirmation bias). Seeing is not believing – rather, believing is seeing. Despite specific scientific methods to address this bias, it continues to confuse and confound science, leading to errors, mistakes, and failures – many on a monumental scale.

Confirmation bias begins the moment a person has a belief, regardless of its origin or truth, even if the belief is harmful to the person who has it. (Remember Prosper-René Blondlot and the great fiasco of N-Rays?)

Why would we evolve such a seemingly maladaptive trait? Surprisingly, despite the damage, without confirmation bias, forward progress in science would stop. It’s even essential to human thinking.

In this Science on Tap, Dr. James C. Zimring will explore how and why confirmation bias both drives science forward and can also drive it off a cliff. He’ll explore the questions:

• How do we harness the remarkable advantages of confirmation bias?
• How does promoting diversity maximize those advantages?

James C. Zimring MD, PhD holds the Thomas W. Tillack chair in experimental pathology at the U of Virginia. For the last 20 years, Dr. Zimring has been highly involved in teaching the “science about science” at the graduate and undergraduate levels, as well as a course on scientific thinking for high school. Dr. Zimring has published two books on the topic: What Science is and How it Really Works (Cambridge University Press) and Partial Truths (Columbia University Press).

From heart-breaking to hilarious, The Story Collider show is a live storytelling event featuring stories from people from all walks of life about how science has affected their lives. Whether you wear a lab coat or haven’t seen a test tube since grade school, science is shaping all our lives.

Every year, The Story Collider hosts live shows – in person and online – around the world with all kinds of storytellers: researchers, doctors, and engineers, of course, but also patients, poets, comedians, and more. Our team’s favorite stories from those shows land on our weekly podcast. They’re all true and all very personal.

Science on Tap OR WA is excited to be partnering with them for an evening of true, personal stories about science. Speakers include:

• Amanda Pluntze        
• Justin Bohling
• Marley Parker                 
• Jackie Wirz  (our own MC!) – “Mental health in science. What does it mean to have a broken brain in an intellectual profession? How do you redefine success? How do you redefine yourself?! All questions I grapple with while also discussing the art and science of the HPLC.”
• Mark Pitzer  (a favorite speaker of ours!) – Eager to impress both his Ph.D. advisor and a charming young woman, Mark, a young graduate student in Neuroscience, stumbled into a near-disastrous experiment in both love and lab work. Mark recounts how a lab mishap reshaped his approach to science and his understanding of relationships. 

The word “shark” has historically conjured images of a mindless, man-eating machine. Yet there are over 500 shark species of all shapes and sizes, consuming everything from seagrass to marine mammals. All are critical to our oceans, and their presence usually indicates that an ecosystem is healthy. However, in order to reverse their decline, we need to know more about them.

How do sharks behave?
What is their population size?
How old do they get?
How many young do they have?

Getting answers is a huge challenge – how do you study something that is out of sight and sometimes larger than your own boats? Oregon’s waters are home to 15 shark species, but a dedicated research program was only recently established for these animals – the Big Fish Lab at Oregon State University. At this Science on Tap, learn about their innovative research methods, from animal-borne cameras and “FitBits” to satellite tracking to drone footage, as well as why this information is critical to conservation.

Some of their scientists have been featured on Shark Week, BBC and National Geographic, so come prepared with all of your questions about sharks, shark science, and sharks in the public eye!

Dr. Alexandra (Alex) McInturf (she/her) is a research associate in the Big Fish Lab (BFL) at Oregon State University. Her research focuses on the social lives of sharks and tracking the movements and assessing the diets of many species. She completed her PhD in Animal Behavior at the University of California, Davis in 2021. She has been with the Big Fish Lab since then, where she conducts her research, mentors the BFL’s many undergraduate and graduate students, and leads community engagement efforts.

What’s it like to work on the front lines of a wildfire? 
How and why are wildfires changing in the Northwest?

This talk will jump into both of these topics, while also expanding on how you can prepare for a future of fire in the Northwest. 

Amanda Monthei spent four years working as a wildland firefighter—including two years as a US Forest Service hotshot (a highly-trained team) based in the Mt. Hood National Forest. Her work gave her a first-hand glimpse at the way PNW ecosystems are shifting and how both wildfire and climate change play a critical role. This talk will give you an inside glimpse at what this unique job entails, as well as the challenges facing wildland firefighters right now. 

She’ll also address why our temperate rainforests no longer feel like the wildfire-safe haven they once were. Believe it or not, fire belongs in these “wet side” ecosystems! But while infrequent, these fires tend to be catastrophically large and fast-moving – take the Labor Day fires of 2020 as an example of how these ecosystems can burn. Explore why this relationship is expected to grow more tenuous as climate change brings more extended drought and other climactic changes to the Northwest. 

Amanda Monthei left firefighting in 2019 and found a niche career in writing about wildfire, including for outlets like The Washington Post, The Atlantic, Deseret News, Patagonia and NBC News. She also produces and hosts a podcast, Life with Fire, which examines our relationship with wildfires and how we can better coexist with them. She lives in Bellingham, WA. 

Have you ever sat down at a bar, ordered a beer, and thought to yourself, “Why do humans even have so many specific genes for breaking down alcohol?” This is what happens when a guy with a PhD in Molecular and Medical Genetics from OHSU starts making booze professionally. The answer, as it turns out, takes you a long way back in human history; our relationship with yeast (the organism that makes alcohol), predates human evolution.

At this Science on Tap, Dr. Kevin McCabe, Winemaker, Enologist, and Beekeeper at Double Strand Wine, will take you through the history of primate alcohol consumption, the importance of yeast and alcoholic fermentation to human history, and how early microbiology turned the tables on yeast and gave humans control over our boozy destiny.

The 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.

The hidden role of fungi inside and all around us.

From beneficial yeasts that aid digestion to toxic molds that cause disease, we are constantly navigating a world filled with fungi. Our health and well-being depend on an immense ecosystem of yeasts and molds inside and all around us.

Come on a guided tour of a marvelously unseen realm, describing how our immune systems are engaged in continuous conversation with the teeming mycobiome inside the body, and how we can fall prey to serious and even life-threatening infections when this peaceful coexistence is disturbed. Our speaker also sheds light on our complicated relationship with fungi outside the body, from wild mushrooms and cultivated molds that have been staples of the human diet for millennia to the controversial experimentation with magic mushrooms in the treatment of depression.

Drawing on the latest advances in mycology, Molds, Mushrooms, and Medicines reveals what scientists are learning about the importance of fungi to our lives, from their vital role in supporting the ecosystems on which we depend to their emerging uses in lifesaving medicine.

Nicholas Money is a mycologist and professor at Miami University in Oxford, Ohio.
