The Ross Island Lagoon, which sits in the center of the four-island complex known as Ross Island, is a byproduct of decades of mining. In addition to industrial purposes, the lagoon also has a long history of being used recreationally and provides habitat for a variety of vulnerable plant and animal species.
In 2015, researchers began to see cyanobacterial blooms in the lagoon. Cyanobacteria is a type of bacteria which can pose a serious threat to the health of animals and people who come into close contact with the water. When present, it gives the water a bright green appearance.
Because the lagoon is a warm, stagnant pool, it’s an ideal breeding ground for cyanobacteria. And it’s only getting warmer due to climate change. The tide from the Willamette pulls the cyanobacteria out into the river’s main flow, contaminating the rest of the water. The Oregon Health Authority routinely releases warnings urging against recreational river use during warmer seasons because of this.
Since 2017, Oregon State University and the Willamette River group the Human Access Project have been working on reducing these Lagoon blooms. There is work being done by different groups to address the cyanobacterial blooms in the Ross Island Lagoon. Desirée Tullos, professor of Water Resources Engineering at Oregon State University, joins us to share more.

A growing number of Oregon tribes have been investing in equine therapy for youth struggling on reservations and in foster care. Both the Confederated Tribes of Umatilla Indian Reservation and the Confederated Tribes of Warm Springs have developed programs in the last three years. And the Confederated Tribes of Grand Ronde, Klamath Tribes and Burns Paiute Tribe have plans to launch programs, some as soon as this summer. Nancy Marie Spears is the Indigenous children an d families reporter for The Imprint. She has been reporting on this trend and joins us to share more.

Live Nation wants to develop a 3,500 capacity venue in Portland’s central eastside. The company, which also owns Ticketmaster, controls an estimated 60% of concert venues across the country and also serves as one of the nation’s biggest artist management companies. Earlier this summer, the Department of Justice sued Live Nation, seeking to break up their “monopoly and restore competition for the benefit of fans and artists.” We hear from reporter Katie Thornton, who wrote about Live Nation’s quest to enter Portland for The Guardian. We also hear from Willamette Week reporter Anthony Effinger, who wrote about an alternate effort from local music promoter Monqui Presents to open a mid-sized venue at  the Lloyd Center.

Since the extreme heat dome in the Pacific Northwest in 2021, researchers have been busy trying to identify all the different effects that heat had on trees and forests. One of those researchers is Chris Still, a professor in the college of forestry at Oregon State University. He says a collaboration with the U.S. Forest Service using satellite data is revealing the swaths in the region that were most damaged. Researchers have also found that tree growth after a heat event does not seem to be as resilient compared to growth after a drought. Still joins us to share more about the research and what it may portend for future heat domes and other extreme heat events that are likely as the planet continues to warm.

Cities across the Pacific Northwest are struggling to handle a growing number of requests for public records such as court documents, police reports and emails between public officials. To test those systems, the investigative news outlet InvestigateWest sent the same records request to 15 cities across Oregon, Washington and Idaho. Some took months, or charged hundreds of dollars, to fulfill the requests.

Daniel Walters reports on democracy and extremism for InvestigateWest. He joins us to share more about what he found and the vital role public records play in holding governments and agencies accountable. 

President Joe Biden’s withdrawal from the 2024 election is reverberating across the nation and the Pacific Northwest’s political world. The news comes less than a month before the Democratic National Convention is scheduled to begin in Chicago. Earl Blumenauer, Democratic Congressman representing Oregon’s 3rd district, and James Manning, state senator representing Eugene, are among the local delegates heading to the convention. They join us to share their reactions.

Peter Courtney died this week at the age of 81. He was first elected to the Oregon House of Representatives in 1980. He moved to the Senate side in 1999 and became Senate President four years later. Courtney, who grew up in what he liked to call “West by God Virginia,”  served for 38 years in the legislature, including a  record 20 as the senate president. In an institution that he cared about deeply, he was a kind of institution himself: passionate and bombastic, often dramatic and sometimes dour. We talked to Peter Courtney many times over the last 15 years. We listen back to our conversation with him in January of 2022, soon after he announced he would not be seeking re-election.

Artificial Intelligence is radically changing how we work, learn, play and socialize, from virtual assistants helping organize our day to bots that can score Taylor Swift tickets or write college-level essays. But that vast computing capability may also come at a cost, generating results that are rife with bias if the data that was used to train AI systems is itself biased against or excludes certain groups of people. To counter this issue, we hear about the efforts of two engineering and computer science doctoral students in the Pacific Northwest. 

At the University of Washington, Kate Glazko led a team of researchers on a study that found that the popular AI application ChatGPT routinely ranked job seekers lower if their CVs mentioned an award or recognition that implied they had a disability such as autism or blindness. At Oregon State University, Eric Slyman developed computing instructions that can be used to train AI to be less biased against marginalized groups when generating image search results. Slyman and Glazko join us for more details. 

Wildfires in the West are becoming more common and severe. Nationwide, national disasters are becoming worse and insurance premiums are rising. In Southern Oregon, residents are seeing spikes in their premiums or are deciding to change insurance companies. One Ashland insurance agent saw a premium on his rental property jump 86%. And for residents in remote, wooded areas, the insurance options are shrinking. We learn more from Juliet Grable, a JPR contributor covering the issue.   

Have you ever heard a color, or seen a piece of music? Maybe you’ve tasted a sunset, or felt a particular smell? If so, you might have synesthesia. It’s a phenomenon in which one or more sensory pathways blend in the brain to create a new experience. Researchers aren’t sure how many people have synesthesia, but estimates range from 1 in 200 to 1 in 20 people.

Elizabeth Schwartz is a freelance writer and music historian from Portland; Forest Mountain Lion is a musician from Eugene; and James Duckwell is a career and technical education teacher at Portland’s Roosevelt High School. They all join us to talk about their experiences with synesthesia, along with Mark Stewart, a professor of psychology at Willamette University who studies the phenomenon.
