Science On Tap: The Counting of Crows
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. • 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. Brodie Cass Talbott works at Bird Alliance of Oregon, where he has been educating both adults and kids about birds since 2018. He leads birdwatching tours near and far, teaches classes on bird ecology and identification, and works to engage the growing birdwatching community in the conservation work that Bird Alliance of Oregon has been doing since 1902.

Science On Tap: Thigmomorphogenesis, or Why Most Trees Don’t Fall Over
Back by popular demand! 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? An arborist, a dendrologist, and educator, Casey Clapp is the principal consultant with Portland Arboriculture and co-host/co-creator of CompletelyArbortrary, a weekly podcast about trees and other related topics.

Science On Tap – Sleep & Snuggling: The Key to Social Connection
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.

Science on Tap – K9 Conservationists: Dogs Helping Wolf Research
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.

Science On Tap: Budding Science – Cannabis in Reproductive Health
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 Jamie O. Lo, M.D., M.C.R. is an Associate Professor in the Department of Ob/Gyn and Department of Urology at OHSU.

Science On Tap – When the Window Breaks: How Vision is Rebuilt
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.

Science On Tap – How Did the Frog Cross the Road? Portland’s Frog Tunnel
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. Alyson Yates is a graduate student in the School of Earth, Environment and Society at PSU and a freelance photojournalist. Led by a motivation to conserve lesser-known and misunderstood wildlife, she has embarked on adventures around the world to bridge science and storytelling. Her work has been featured by National Wildlife Magazine, Bats Magazine, Merlin Tuttle’s Bat Conservation, OSU, and other media outlets.

Science On Tap: Indigenous Science – Seed Banks for Eco-Restoration
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. Josephine Woolington is a writer and musician based in her hometown of Portland, Oregon.
