Maxine Dexter could have spent the last few weeks of the year relaxing with loved ones while preparing to represent the congressional district that spans Portland, Hood River and Mount Hood.Instead, after sealing her victory in Oregon’s 3rd Congressional District in November, she continued to do what she’s done for nearly two decades: pull 10-hour shifts for six days straight in intensive care and tended to patients with lung disease.Dexter, a former state representative, has been a critical care doctor and pulmonologist at Kaiser Permanente for nearly two decades. She chose to work pretty much to the end of the year to support her patients and colleagues.“Health care systems aren’t doing very well right now, so they’re not necessarily able to replace me,” Dexter told the Capital Chronicle. “And I felt like I needed to get my team or my partners through the holidays.”Dexter, who just turned 52, will be sworn into Congress on Friday along with other newly elected members, including Janelle Bynum, who won Oregon’s 5th Congressional District seat. Both women, Democrats who have served in the majority in Oregon’s House, enter the partisan fray in Washington D.C. in the minority, with Republicans in control of the House, Senate and White House.Republicans also controlled the House over the past two years, a time that’s been marked by political brawls but scant action. Though they continue to hold the power in the House, they hold a majority of only five seats, and that could mean more chaos, analysts say.Dexter, a progressive who backs easing access to abortions, enacting gun control and moving toward a single-payer health care system, said she will not prejudge any of her congressional colleagues. She said she will work with anyone with whom she can find common ground on an issue. But when pressed about the agenda of the incoming Trump administration and his pledge to deport illegal immigrants and expand fossil fuel drilling, she acknowledged a potentially tough road ahead for a progressive like herself.“I’m deeply concerned,” she said. “We are not headed in the right direction.”Her two children, both in college, agree, and they don’t have much faith in government, she said. That’s one reason she decided to run.In preparing for her new life, she leased an apartment within walking distance to the Capitol, attended orientation sessions with other freshmen and combed through policies and procedures. She also reached out to other physicians in Congress, including Minnesota’s Rep. Kelly Morrison, a obstetrician, and consulted the other Democratic representatives in Oregon: Reps. Suzanne Bonamici, Val Hoyle, Andrea Salinas and retiring Rep. Earl Blumenauer, who’s 76 and represented Oregon’s 3rd District for nearly three decades.He and his staff worked closely with Dexter to ease her transition.“She’s a very quick study,” Blumenauer told the Capital Chronicle. “I don’t know that I’ve seen a new member of Congress get engaged as quickly and as thoroughly as Maxine. I could not be more impressed.”Maxine Dexter, center in blue hat, poses with wet, cold supporters in the early days of her first campaign for the Oregon House in 2020.Modest backgroundDexter was not destined for Congress. She grew up with a brother in a working class family in Bothell, Washington, about 20 miles northeast of Seattle. Her father sold car parts, barely making enough to get by. Their home life was tumultuous and her parents got divorced.She had no role models to pursue medicine or politics. Her home had no books, and no one in her family had earned a college degree. But Dexter’s family life prepared her for becoming a physician. She learned about mental illness from her mother, who struggled with profound issues, Dexter said, and she learned to care for patients from her grandmother, who had diabetes and suffered a series of amputations. Dexter embraced the role of being a nurse and tending to her grandmother’s wound care.At school, she impressed her teachers and was assigned to classes for gifted students. One of her favorite teachers introduced her to the idea of college and asked what she’d like to be.She decided she wanted to care for people, as she cared for her grandmother, and become a doctor.At 16, she got a job at Albertsons, first working in the bakery, then as a checker and finally as a manager. She also joined the United Food and Commercial Workers International Union, which represents grocery store workers.Her earnings helped pay for her college education in Seattle at the University of Washington. Though a pre-med student, she studied journalism and political science as an undergrad because she knew that in med school, she’d have little time for liberal arts. She worked as a sportswriter at the school newspaper and even freelanced some stories for the Seattle Times. She also read the New York Times voraciously, helped by the fact that she could buy it for $1 a week as a student.Her college years, as for many, were a time of discovery.“It was like the whole world was open to me at the University of Washington,” Dexter said. “There were so many really interesting things to study.”She was interested in the political system, constitutional law and health policy and did a Ford Foundation internship on the subject that laid a foundation for her future path.“I knew I was going to work on health policy someday,” Dexter said.Dexter also found love at university.She and her husband both earned their medical degrees from the University of Washington. He became a primary care physician and now works at Kaiser Permanente in Portland. She pursued a postgraduate fellowship in pulmonary and critical care at the University of Colorado in Denver because she enjoys responding to an emergency.“I have always been someone who likes thinking on their feet and being the person who helps in a crisis,” Dexter said.As a physician, she’s seen people at their worst, and she’s cared for many patients who’ve struggled in their lives. Some have had to decide between buying their medications or paying for child care.“At the end of the day, we have got to create a society where people can live dignified, stable lives when they’re working full time,” Dexter said.State Rep.

Mitch Greenlick, a former Kaiser Permanente research director and professor at Oregon Health & Science University. Dexter won the primary and was sworn into office that June after Greenlick died in office.Dexter served nearly two terms in the state House and supported a range of Democratic issues, from safe gun storage and a ban on undetectable ghost guns to reform in the pharmaceutical industry and an expansion of Medicaid benefits to all low-income immigrants.She also worked on bipartisan packages, including a $100 million drought and water security package in 2023 and a right to repair law which took effect Wednesday and is expected to make it easier and cheaper for consumers to fix their devices.But she’s most proud of two initiatives. One stems from a patient in 2022. A young woman who took what she thought was a pain pill overdosed on what turned out to be fentanyl. Dexter said on her website that she worked all night trying to save the woman’s life.“I was the one who had to give their mother, friends and extended family the heart-breaking news,” she said. “I realized this was a tragedy that could happen to anyone’s children, even my own. I had to take action.”The following year she championed the passage of a package aimed at saving people from overdoses by making the opioid reversal drug, naloxone, more available in restaurants, stores, police departments and schools and other public buildings.The other accomplishment she cites was also in 2023, when Dexter chaired the housing committee. Dexter played a central role in putting together a $200 million housing and homelessness package pushed by Gov. Tina Kotek that included rent assistance and money for shelter beds and to get 1,200 homeless people into housing.A fellow Democrat, state Sen.

We don’t talk about guns. Like there are certain things that you’re just never going to agree on.”Dexter doesn’t always agree with fellow Democrats, either. Rep.

How eating oysters could help restore South Australia’s algal-bloom ravaged coast

South Australians are heartbroken about the state’s unprecedented algal bloom. But eating oysters, donating shells and restoring lost reefs will boost ocean health.

South Australians are suddenly hearing a lot about oyster reefs — from government, on the news and in conversations, both online and in person. It’s not accidental. Their state is grappling with an unprecedented and harmful algal bloom. The crisis has drawn attention to another, long-forgotten environmental disaster beneath the waves: the historical destruction of native shellfish reefs. Reefs formed by native oysters, mussels and other aquatic mollusks carpeted more than 1,500 kilometres of the state’s coastline, until 200 years ago. In fact, they went well beyond the state border, existing in sheltered waters of bays and estuaries from the southern Great Barrier Reef to Tasmania and all the way around to Perth. These vast communities of bivalves, which feed by drawing water over their gills, would have helped clean the ocean gulfs and supported a smorgasbord of marine life. Their destruction by colonial dredge fisheries — to feed the growing colony and supply lime for construction — has left our contemporary coastlines more vulnerable to events like this algal bloom. And their recovery is now a central part of South Australia’s algal bloom response. Dominic Mcafee snorkels over a restored oyster reef at Coffin Bay. Stefan Andrews, CC BY-ND Rebuilding reefs South Australia’s A$20.6 million plan aims to restore various marine ecosystems, with two approaches to restore shellfish reefs. The first is building large reefs with limestone boulders. These have been constructed over the past decade with some positive results. Four have been built in Gulf St Vincent near Adelaide. Boulder reefs provide hard, stable substrate for baby oysters to settle and grow on. When built at the right time in early summer, when oyster babies are abundant and searching for a home, oyster larvae can settle on them and begin growing. But these are large infrastructure projects – think cranes, barges and boulders – and therefore take years to plan and execute. So alongside these large reef builds, the public will have the chance to help construct 25 smaller community-based reefs over the next three years. From Kangaroo Island to the Eyre Peninsula, these reefs will use recycled shells collected from aquaculture farms, restaurants and households using dedicated shell recycling bins. There will soon be a dedicated website for the project. The donated shells will be cleaned, sterilised by months in the sun, and packaged into biodegradable mesh bags and degradable cages to provide many thousands of “reef units”. From these smaller units, big reefs can grow. This combined approach — industrial-scale reefs and grassroots restoration — reflects both the scale of the ecological problem and the appetite for public participation. A 3D model of a community-based reef underwater with panels to monitor oyster settlement. Manny Katz, EyreLab, CC BY-ND What about the algal bloom? Little can be done to disperse an algal bloom of this magnitude once it has taken root. Feeling like powerless witnesses to the disaster, the ecological grief and dismay among coastal communities is palpable. Naturally, attention turns to recovery – what can be done to repair the damage? This is where oysters come in. They cannot stop this bloom. And their restoration is not a silver bullet for addressing the many stressors facing the marine environment. But healthy ecosystems recover faster and are more resilient to future environmental shocks. For shellfish reefs, South Australia already has some impressive runs on the board. Over nearly a decade we have undertaken some of the largest shellfish restorations in the Southern Hemisphere. Millions of oysters have found a home on our extant reefs, providing filtration benefits and supporting diverse marine life. And although the algal bloom has decimated many bivalve communities, thankfully native oysters have been found to have a level of resilience. During a dive last week we witnessed new baby oysters that had recently settled on the reefs, seeding its recovery. In the past decade we have built a scientific evidence base, practical knowledge, and community enthusiasm for reef restorations that benefits the broader marine ecosystem. This is why shellfish reefs feature so prominently in the algal bloom response plan. A site of oyster reef restoration in South Australia. Stefan Andrews, CC BY-ND Where will these new reefs go? We need time to identify the best sites for big boulder reefs. For now, the priority is monitoring the ecological impacts and resilience to the ongoing algal bloom. But work on community-based reef projects has already begun . These reefs will broaden our scientific understanding of how underwater animals and plants find them. Sites will be chosen based on ecological knowledge and community interest in ongoing marine stewardship. There are many ways communities can take part. Community involvement and education is a cornerstone of the work, and individuals can recycle their oyster, scallop and mussel shells. The public can also volunteer time to join shell bagging and caging events, and even get involved building the reefs. In time, there will opportunities for the community to help with monitoring and counting the oysters and other critters settled on the recycled shell. A native oyster reef in Coffin Bay, South Australia. Stefan Andrews, CC BY-ND Future built from the past The impact of this harmful algal bloom is real and ongoing. But in responding to it, South Australians are rediscovering a forgotten marine ecosystem. Rebuilding shellfish reefs won’t fix it — but alongside catchment management, seagrass restoration, fisheries management and improved monitoring and climate action, it is a powerful tool. With the help of communities, reefs that were once broken, forgotten and functionally extinct, can be returned. It will take time for these reefs to support cleaner waters and richer marine life. But these community initiatives can show people that we all have a role to play in caring for coastlines.

Tijuana River sewage still pollutes the San Diego Coast. She’s fighting to clean it up

The Tijuana River’s sewage contamination continues to sicken communities in southern San Diego County. San Diego County Supervisor Paloma Aguirre has become a leading force in pushing for binational fixes and emergency funding to protect public health.

In summary The Tijuana River’s sewage contamination continues to sicken communities in southern San Diego County. San Diego County Supervisor Paloma Aguirre has become a leading force in pushing for binational fixes and emergency funding to protect public health. Hours after a November storm, the Tijuana River flooded a grove of trees in Imperial Beach, gushed through a row of calverts and exploded into mounds of fetid foam.  This is ground zero for the contaminated river, which sickens thousands of people in southern San Diego County. “The Tijuana River is one of, if not the most polluted, river in the entire United States,” said San Diego County Supervisor Paloma Aguirre, who viewed the overflowing river wearing black rain boots and a hot pink respirator mask. “The river is carrying dangerous chemicals, pollutants, pathogens and toxic gases that are impacting South San Diego communities.” The site, known as the Saturn Boulevard hot spot, is part of a system of polluted waterways and failed sewage treatment plants in the cross-border region. In the ocean, the contamination leaves swimmers and surfers with breathing problems, digestive illness and rashes. Unsafe conditions have closed parts of the Imperial Beach shoreline for three years. Last year, researchers discovered that the pollution is airborne as well. Foul-smelling hydrogen sulfide emissions near the river sometimes rise hundreds of times higher than the state’s odor threshold. At those levels the gas triggers headaches, nausea, eye irritation and respiratory distress. And there are other chemicals, viruses and bacteria in the mix.  For children, the effects are worse, said Tom Csanadi, an Imperial Beach physician who has been active in the issue. Their lung surface area to body size is higher, which means they absorb more toxins. Children breathe faster than adults and they’re still growing, so it can affect their body tissues more severely. There are 11 schools within three kilometers of the hot spot. “It could lower IQ, stunt cognitive development,” Csanadi said. As a surfer, activist and elected leader, Aguirre has spent two decades tackling this problem, which she considers one of the worst environmental crises in the country. “She’s been at the forefront of the advocacy side of this for a long, long time, before her political career even started,” said Falk Feddersen, an oceanographer with Scripps Institution of Oceanography who has mapped sewage flows up the coast from Mexico. A cocktail of chemicals While storm water seeped across the road at the hot spot, a swiftwater rescue truck drove through puddles, scanning for stranded motorists. The culverts under the crossing were installed to keep flooding under control, but they also churn the water, spewing noxious gas and other pollutants.  “The unintended consequence is that it’s exacerbating the release of all the molecules and aerosols into the air,” Aguirre said. “It’s literally rocketing them into the environment.” Hydrogen sulfide, with its distinctive rotten egg odor, is an indicator of that toxic brew, said Kim Prather, an atmospheric chemist at Scripps Institution of Oceanography. She raised the alarm about airborne pollution from the Tijuana River last year.

Photo by Adriana Heldiz, CalMatters “That’s one in a cocktail of thousands of compounds,” she said. “It’s a blessing that it smells. I know it sounds strange, but it tells you to get away.” Aguirre described her own struggles with Tijuana River pollution, including migraines, chest pain, shortness of breath, and waking in the middle of the night to an odor she likened to a “porta potty.” Recent improvements to wastewater treatment plants in the U.S. and Mexico have reduced water pollution by keeping tens of millions of gallons of sewage out of the ocean each day. Aguirre and others celebrate that news, but note the river still contaminates surrounding areas. More big upgrades are in the works on both sides of the border, but fixing the Saturn Boulevard hot spot quickly could offer immediate relief, Aguirre said. “This is a very specific and low hanging fruit that will at least begin to mitigate the amount of gases being released into the air and benefit tens of thousands of people that live here,” she said. Waves of pollution Tijuana River pollution dates back to at least the 1930s, when the U.S. and Mexican governments built the first cross-border sewage plants. As Tijuana’s population soared with its booming industry, the city’s waste outstripped its treatment systems. Plant failures and sewage spills became common in the early 2000s, along with frequent beach closures along the south San Diego coast. That’s when Aguirre encountered cross-border pollution in the surf at Imperial Beach. Growing up in Puerto Vallarta Mexico, she was used to surfing in muddy water after rains, so the discolored waves didn’t seem worrisome.  “I remember going out here in Imperial Beach while the water was chocolate brown, not knowing that it’s nothing like what I was used to, because that was sewage,” she said. She was the only one at the beach that day, except for a man posting signs stating “Clean water now.” He was Serge Dedina, executive director of the environmental group WildCoast, and he enlisted her in the fight against sewage pollution. Aguirre first volunteered for the organization and soon joined its staff. She worked there for more than a decade, while earning a master’s degree in marine biodiversity and conservation at Scripps Institution of Oceanography. At WildCoast she organized a citizens’ group, advocated for improved water testing using DNA analysis, and served on working groups for a binational agreement on cross-border pollution, called Minute 320. When Dedina was elected mayor of Imperial Beach in 2014, Aguirre saw a path to solving the sewage problem. “I thought, well, if he can do it I can do it,” she said. “And I built on the momentum that he was able to create on this issue.” San Diego County Supervisor Paloma Aguirre wears a respiratory filter mask while standing near a section of the Tijuana River in San Diego on Nov. 21, 2025.

With a bigger platform, she called on California and the federal government to declare a state of emergency over the border pollution problem and lobbied to classify the area as a Superfund site. Those efforts haven’t gained traction, but other angles yielded results. Imperial Beach sued the International Boundary and Water Commission with the city of Chula Vista and Port of San Diego in 2018, alleging that it violated the Clean Water Act and other federal laws by failing to control coastal sewage pollution. They settled the lawsuit in 2023 with a promise of more resources and binational cooperation.  “My tenure as mayor of IB really focused on advocating and working in a bipartisan fashion to secure the additional funding that was needed,” to fix cross-border pollution, she said.

Photo by Adriana Heldiz, CalMatters Aguirre led delegations of local officials to Washington, D.C. to drum up money for costly infrastructure upgrades needed to get the sewage problem under control. She met with White House officials in both the Biden and Trump administrations, and with lawmakers who had served as Navy SEALS and had experienced the pollution problem at BUD/S, the Navy SEAL training program in Coronado. In July, Aguirre won a special election for an open San Diego County Board of Supervisors seat. She immediately led county plans to study the health effects of cross-border pollution and asked the state for $50 million to fix the Saturn Boulevard hot spot.  “She’s moved a problem that has been stuck, when other people could not,” Prather, the Scripps atmospheric chemist, said. Sewage spills prompt quick fixes The long-standing pollution problem came under new scrutiny in 2017, when a spill from a damaged line in Mexico dumped an estimated 143 million gallons of wastewater into the Tijuana River, sending foul odors wafting through the region. That accident revealed just how dilapidated the aging infrastructure had become. “That’s one of the reasons why things are so horrific, because they’re playing catch up on fixing these things when they have catastrophic failures,” said Feddersen, the Scripps oceanographer. In early 2022, another major spill released hundreds of millions of gallons of sewage-tainted water across the border for two and a half weeks.  That summer, San Diego congress members freed up more than $300 million that had been authorized for wastewater treatment upgrades through the United States-Mexico-Canada Agreement. Mexico committed $144 million to replace failing sewage treatment facilities in Tijuana, with an updated treaty between the two countries known as Minute 328. In 2024, the lawmakers persuaded the Biden administration to add another $370 million to repair the aging South Bay International Wastewater Treatment Plant near the border, Rep. Scott Peters said. After decades of deterioration, major improvements came online this year. The South Bay International Wastewater Treatment Plant, which was barely operable, is now fully functioning and expanded its capacity from 25 million to 35 million gallons of wastewater per day. The project was expected to take two years, but was completed in 100 days, according to the U.S. International Boundary and Water Commission.

The commission, which manages the wastewater systems, has spent $122 million on the first series fixes, and the full project will cost $650 million. Although the Trump administration has clawed back federal funding for many projects, it has doubled down on the cross-border sewage problem, Aguirre said. In July U.S. Environmental Protection Agency Administrator Lee Zeldin met with his Mexican counterpart to seal the environmental deal. In April Mexico repaired its Punta Bandera plant, located on the coast about six miles south of the border. The plant had failed completely in 2020 and was dumping raw sewage into the ocean. It now handles 18 million gallons of wastewater per day. That’s a big boost for beach safety, said Feddersen, whose research tracked the flow of sewage in ocean currents and modeled scenarios for reducing it. “The best bang for the buck, the greatest reduction in beach closure and reduction in human illness, was fixing Punta Bandera,” he said. Yet, the Tijuana River still threatens residents in its watershed with untreated sewage and industrial chemicals from maquiladoras in Tijuana. That includes solvents, heavy metals and toxins known as PFAS, or “forever chemicals,” Prather said. “The river right now is a wastewater treatment plant without any processing,” she said. Removing the culverts would eliminate the turbulence that sprays out hydrogen sulfide and other toxins. The county plans to finish a feasibility study on the project by January. That project would keep contaminants out of the air, but not out of the water. Aguirre also wants new infrastructure to clean up the Tijuana River on the U.S. side. The recent binational Treaty, Minute 328, includes that option, and the International Boundary and Water Commission is exploring what it would take to divert and treat the river flows. There’s no funding for the project yet, but Aguirre says it’s on her agenda. “Rivers are diverted up and down,” she said.  “It’s doable. Is it expensive? Yes. Are our lives in South San Diego worth it? Yes.”

Germophobes Can Breathe Easy On Airplanes, In Hospitals, Experts Say

By Dennis Thompson HealthDay ReporterFRIDAY, Dec. 5, 2025 (HealthDay News) — Germophobes can breathe a little easier when visiting a hospital or taking an airplane trip, a new study says.The ambient air on planes and in hospitals mostly contains harmless microbes typically associated with human skin, researchers reported Dec. 4 in the journal Microbiome.The cutting-edge study analyzed germ samples captured on the outer surface of face masks worn by air travelers and health care workers, researchers said.“We realized that we could use face masks as a cheap, easy air-sampling device for personal exposures and general exposures,” senior researcher Erica Hartmann, an associate professor of civil and environmental engineering at Northwestern University in Evanston, Illinois, said in a news release.“We extracted DNA from those masks and examined the types of bacteria found there,” Hartmann said.Overall, the team analyzed germs drawn from masks worn by 10 air travelers and 12 health care professionals. Travelers turned in their masks following a flight, hospital workers following a shift.Researchers also analyzed germs captured by an aircraft cabin filter that had been used for more than 8,000 hours.Overall, the team found 407 distinct species of microbes.“Somewhat unsurprisingly, the bacteria were the types that we would typically associate with indoor air,” Hartmann said. “Indoor air looks like indoor air, which also looks like human skin.”A few potentially disease-causing germs did show up, but they were in extremely low amounts and without signs of active infection, researchers said.Hartmann’s team came up with the study idea in January 2022, amid the COVID pandemic.“At the time, there was a serious concern about COVID transmission on planes,” Hartmann said. “HEPA filters on planes filter the air with incredibly high efficiency, so we thought it would be a great way to capture everything in the air.”“But these filters are not like the filters in our cars or homes,” Hartmann added. “They cost thousands of dollars and, in order to remove them, workers have to pull the airplane out of service for maintenance. This obviously costs an incredible amount of money, and that was eye opening.”To beef up their project, the team turned to a much cheaper alternative: face masks.They also decided to include hospitals as another study locale.“As a comparison group, we thought about another population of people who were likely wearing masks anyway,” Hartmann said. “We landed on health care providers.”The results indicate that people themselves are the main source of airborne microbes in enclosed settings, and that most of the germs come from people’s skin rather than from any illnesses, researchers said.Although the results show indoor air is relatively safe, researchers noted that infectious germs also spread through other routes — most importantly, touch.“For this study, we solely looked at what’s in the air,” Hartmann said. “Hand hygiene remains an effective way to prevent diseases transmission from surfaces. We were interested in what people are exposed to via air, even if they are washing their hands.”SOURCES: Northwestern University, news release, Dec. 3, 2025; Microbiome, Dec. 4, 2025Copyright © 2025 HealthDay.
