Large majorities of U.S. adults support the role of the courts and Congress in serving as checks on presidential power, even though the public has less trust in all three branches of the federal government than it does in many other American institutions and professions, according to a survey from the Annenberg Public Policy Center (APPC) of the University of Pennsylvania.

The policy center’s Institutions of Democracy survey finds that trust in the U.S. Supreme Court has continued to decline since the court’s 2022 Dobbs ruling overturning the constitutional right to abortion codified in Roe v. Wade. Trust in the nation’s highest court has slid 27 percentage points since 2019, from 68% six years ago to 41% in March 2025. Nearly a third of those surveyed (32%) say they have no trust at all in the Supreme Court to operate in the best interests of “people like you.” In just the past 10 months, since May 2024, the percentage of those with no or low trust in that court grew to 59% from 55%.

Highlights

The survey, conducted March 6-16, 2025, with a nationally representative sample of 1,363 U.S. adults who are part of APPC’s ongoing survey panel, also finds that:

  • A majority of Americans (60%) think the country is going in the wrong direction and a slim majority (54%) think a year from now the economy will be worse than it is today.
  • A strong majority (69%) of Americans say the president should follow a Supreme Court ruling, even if the president believes the ruling prevents him from protecting the country from a terrorist attack.
  • Compared with 20 years ago, Americans are much less confident that Supreme Court justices will make decisions without considering their personal views and find the ethical practices of the justices to be significantly worse.
  • Jury service is a way to bolster trust in the legal system and is positively associated with views of increased legitimacy and trust in the courts, and more positive views of judges. But fewer people report being called for jury duty and a smaller proportion of those who are called are serving.

“Because judges have neither the power of the purse nor of the sword, it is especially important that they retain the respect and confidence of the citizenry and that the public appreciates the indispensable role that the courts play in protecting our rights, sustaining our system of government, and helping the country navigate contentious issues and times,” said Kathleen Hall Jamieson, director of the Annenberg Public Policy Center.

For the data, see the topline.

Americans support a system of checks and balances

Less than a quarter of U.S. adults endorse the idea of unchecked executive action. Even among Republican voters, who are the most supportive of a president in their own party, only a minority support unconstrained executive action. (Consistent with many surveys, this analysis includes independent voters who express a preference for either the Democratic or Republican party with that party’s data.)

“Americans do not think the president should have the ability to act unconstrained by the courts and Congress,” said Matt Levendusky, director of APPC’s Institutions of Democracy division and a Penn political science professor, who, with APPC research analyst Shawn Patterson Jr., wrote about the issue for NBC News. “Democrats, Republicans, and independents alike believe that the courts and Congress should be able to check the president’s actions.”

A majority of Americans do not think a president should be able to…

  • Ignore court rulings: Two-thirds (66%) disagree with the statement that the president should be able to ignore court decisions he believes intrude on his constitutional authority, while 16% agree. Just 27% of Republicans, 20% of independents, and 5% of Democrats agree.   
  • Pick judges without Senate consent: Two-thirds (67%) disagree with the idea that the president should be able to appoint judges of his choosing regardless of whether the U.S. Senate agrees with the selections, while 18% agree. Under a third (31%) of Republicans agree, as do 13% independents and 8% of Democrats.
  • Enact policies without Congressional approval: 60% disagree with the proposition that the president should have the right to enact policies without having those policies voted on by Congress, while 20% agree. A third of Republicans (33%) agree, as do 20% of independents and 10% of Democrats.

The public is more closely divided on whether the president should have the authority to decide how executive agencies will implement bills passed by Congress, though a plurality is opposed, with 40% in opposition and 34% in agreement. Over half of Republicans (56%) agree that the president should have the authority, but just 33% of independents and 17% of Democrats do.

A majority of Americans endorse the essential role of courts in our government:

  • Play a vital role: 84% agree that courts play a vital role in our system of government, including 86% of Democrats, 83% of Republicans, and 81% of independents.
  • Prevent abuse of power: 58% believe the courts prevent elected officials from abusing their power, including 64% of Democrats, 54% of independents, and 51% of Republicans.

Obey the courts – even when faced with terrorism

Compared with data from a 2007 Annenberg survey, Americans today are more likely to say that the president should follow a Supreme Court ruling, even if the president believes that the ruling prevents him from protecting the country against a terrorist attack:

  • 69% say the president should follow the Supreme Court ruling, up from 44% in 2007. Almost a third (31%) now say the president should ignore the ruling.
  • Three-quarters (76%) say that having the president follow the ruling is what is supposed to happen in our system of government, up from 56% in 2007. Under a quarter (23%) say the president is supposed to ignore the ruling.

“People want the president to listen to the Supreme Court and they think that our system of government requires the president to do so,” said Patterson.

Trust in the Supreme Court

Trust in the Supreme Court has continued to sink. In March 2025, 59% of those surveyed report having little (27%) or no (32%) trust in the court to operate in the best interests of “people like you.” Just 41% express confidence that the court is operating in their best interests, with 27% reporting “a moderate amount” of trust, 11% “a lot,” and 3% “a great deal” of trust.

The number of those with no or low trust has risen over the past 10 months to 59% from 55% in May 2024, while the proportion of those with high/moderate trust (41%) has continued to fall from 45% in May 2024. The Annenberg Public Policy Center has been surveying on this question since 2005, when 75% had high/moderate trust and 22% had low/no trust.

Earlier APPC surveys found that trust in the court has plummeted since the 2022 Dobbs decision overturning the half-century-old landmark Roe v. Wade ruling that codified the right to abortion. Americans’ trust in the court, which was 68% in 2019, has fallen 27 percentage points to 41%.

Public views more negative of Supreme Court justices

Compared with 20 years ago, Americans are much less confident Supreme Court justices will make decisions without considering their personal views. Just 37% are very or somewhat confident a new justice appointed by President Trump will make decisions without considering their own personal views, down from 59% in 2005 (when the question referenced President Bush). Nearly two-thirds (63%) are not too/not at all confident a new justice would make decisions without considering their personal views, up from 37% in 2005.

The public also holds much more negative views of the justices’ ethics, as compared with an APPC 2006 survey. The public is currently divided in its views about the justices’ ethical practices: 44% say they are very/somewhat good and 43% very/somewhat bad. In 2006, nearly three-quarters (72%) thought the justices’ ethical practices were very/somewhat good, far more than those who considered them very/somewhat bad (19%).

Compared with 2005, nearly twice as many people say their opinion of the Supreme Court has declined in the past 10 years. Today, 51% say their opinion of the court has declined in the past 10 years, compared with 27% who held that opinion in 2005.

In considering the judicial system apart from the Supreme Court, however, respondents express greater levels of trust in federal court judges (56%) and courts in their state (52%). 

U.S. “on the wrong track” and low trust in government institutions

A majority of Americans feel that in the United States, “things are seriously off on the wrong track” (60%) rather than “generally going in the right direction” (40%). And most (54%) also feel that a year from now, the nation’s economy as a whole will be worse than it is today, rather than better (36%), with 10% saying the country will be “about the same” as it is today.

It is not just the Supreme Court that has low levels of trust. Only business leaders are less trusted than the three branches of the federal government. When the American people are asked how much, if at all, they trust different organizations and professions to act “in the best interest of people like you,” they express the greatest trust in medical scientists (73%), the military (72%), and scientists in general (71%) (combining the responses for a great deal/a lot/a moderate amount of trust), according to APPC surveys conducted in February and March 2025.

By contrast, there is much less trust in the U.S. Supreme Court (41%) and the President (40%), followed by “elected officials” (36%) and Congress (32%). Business leaders (30%) are at the bottom of these groups.

“Even though people say they don’t have much trust in particular government institutions – Congress, the President, the courts – they do express support for our system of government,” Patterson said. “They support the idea of checks and balances, if not the individual branches themselves.”

Limiting the power of the judiciary

In the 2024 Judicature article “The withering of public confidence in the courts,” APPC researchers reported survey evidence suggesting that while the public had greater confidence in the judiciary than the other branches, the distance separating the perceptions of courts from those of other branches has narrowed in recent years. While respondents in the current survey place more trust in the courts in their own state to act in the best interest of people like them than in the Supreme Court, they are also more supportive of some steps to limit the power of those courts.

The survey finds that:

  • Nearly 3 in 10 (28%) agree that Supreme Court Justices who consistently make unpopular decisions should be removed from their position – and 39% feel that way about other judges.
  • A quarter (25%) say that if the Supreme Court started making a lot of rulings most people disagreed with, it might be better to do away with the court altogether, while 16% feel this way about local courts.
  • Over half of those surveyed (55%) say the Supreme Court gets too mixed up in politics – and 65% feel that way about other courts.
  • Over a third (34%) say the right of the Supreme Court to decide certain types of controversial issues should be reduced – and 38% feel that way about other courts.

The positive effects of jury service

“Understanding the workings of the judiciary and the unique role courts play in American government may help foster greater trust in and support for the institution of the courts,” said Ken Winneg, APPC’s managing director of survey research and a coauthor of the Judicature article. As other researchers in communication, legal studies, and political science have written: “to know courts is to love them.”

The APPC survey finds that fewer people report being called for jury service, with 35% saying they were called: 31% were called but did not serve, and 4% served on a jury. Five years ago, in 2020, 41% of Americans had been called for jury service: 33% reported being called but did not serve, and 8% served on a jury. The declining rate of jury service matches other data showing there are fewer jury trials, including a 2023 report from the National Center for State Courts, which reports that the estimated number of jury trials in state courts has diminished since 2007 from 148,558 to 48,764 in 2021.

A regression analysis by Patterson of APPC’s data shows that jury duty is positively associated with greater belief in the legitimacy of the courts, greater trust in the courts, and a greater willingness to ascribe positive traits to judges – for instance, that they are competent, trustworthy, and fair. In its annual Constitution Day Civics Survey, published every year before the holiday on Sept. 17, the policy center has examined civics knowledge among a nationally representative sample of U.S. adults. The survey has repeatedly shown that civics knowledge is positively associated with beliefs in the legitimacy of the courts and the belief that one would receive a fair trial.

“The courts play an important role in educating the citizenry about the importance of the judiciary in our system of government,” Jamieson said.

A more detailed analysis of the survey findings will be published later this year in the journal Judicature.

About the survey

The current findings come from the most recent wave of the Annenberg Public Policy Center’s Institutions of Democracy panel survey, which was conducted March 6-16, 2025, with a nationally representative sample of 1,363 U.S. adults. The margin of sampling error for the complete set of weighted data is ±3.5 percentage points at the 95% confidence level.

For details, see the topline and methodology statement.

The survey questions were developed under the supervision of Matt Levendusky, director of the Annenberg IOD national panel. The analysis and graphics were prepared by APPC research analyst Shawn Patterson Jr. The team supervising the survey includes Kathleen Hall Jamieson, APPC’s director, and Ken Winneg, APPC’s managing director of survey research.

The Annenberg Public Policy Center was established in 1993 to educate the public and policy makers about communication’s role in advancing public understanding of political, science, and health issues at the local, state, and federal levels.

Postoperative recovery is a critical phase in the perioperative period, focusing on minimizing complications and enhancing functional restoration. Enhanced Recovery After Surgery (ERAS) protocols have been highly effective in improving patient outcomes, integrating practices like multimodal analgesia and early mobilization. However, challenges such as stress imbalances and delayed gastrointestinal function persist. Traditional Chinese Medicine (TCM), with its holistic principles, offers unique solutions to postoperative care by focusing on the body's circulation of Qi and blood. TCM’s theories are being integrated with modern digital technologies, forming digital TCM platforms aimed at enhancing perioperative care. These platforms use digital tools to optimize the integration of TCM with ERAS protocols, enhancing precision and individualized care.

Biological Holography and Chaos-Fractal Theory: Foundations for a Perioperative Digital TCM Platform

Biological Holography

TCM’s fundamental principles, including "holistic thinking" and "syndrome differentiation," align with the concept of biological holography, introduced by Professor Yingqing Zhang. According to this theory, each part of an organism reflects the whole, demonstrating the deep interconnections within the body. For instance, the auricle's structure is reminiscent of the human embryo, and pulse divisions correspond to the overall health of vital organs and circulation. This concept of “whole and part” mirrors the body’s overall functional status and is foundational for developing diagnostic platforms that use localized signs, such as tongue characteristics and pulse conditions, as indicators of the body’s overall balance.

Chaos-Fractal Theory

Chaos and fractal theories, central to complexity science, describe the nonlinear and self-similar characteristics of complex systems. In TCM, the concept of “chaos” is reflected in the dynamic balance of Yin and Yang. Just as small changes in chaotic systems can lead to significant shifts, the balance of Yin and Yang in the body determines health outcomes. By applying chaos-fractal theory, TCM practitioners can observe and predict recovery trajectories through patterns that emerge in the body’s dynamic systems, such as heart rate variability (HRV). This approach allows for a more structured understanding of the complex physiological changes occurring during recovery and provides a new way to monitor and optimize postoperative rehabilitation.

Establishment of a Perioperative Digital Chinese Medicine Diagnosis and Treatment Platform

Digital technologies, including AI and wearable devices, are being used to develop a perioperative TCM diagnosis and treatment platform. This platform integrates TCM's holistic concepts with modern digital tools, enabling dynamic monitoring of the body’s internal states and improving individualized care. The platform's primary objective is to maintain homeostasis during the perioperative period, ensuring that even minor fluctuations in patient condition are promptly addressed. By utilizing technologies such as mobile healthcare devices, AI-driven data analytics, and real-time monitoring, the platform facilitates a deeper convergence of TCM with Western medical practices, enhancing postoperative recovery outcomes.

Theoretical Construction of the Perioperative Digital TCM Diagnosis and Treatment Platform

The development of the perioperative digital TCM platform is rooted in complexity science. Surgical trauma, anesthetic intervention, and individual patient responses create a nonlinear system that influences recovery. The integration of biological holography and chaos-fractal theory provides a framework for mapping localized signs, such as tongue and pulse conditions, to the overall health of the patient. Digital tools, such as tongue image analysis and pulse wave signal acquisition, can track changes in physiological states, offering predictive insights into recovery and enabling timely interventions.

Construction of Methodology

The digitalization of TCM’s four diagnostic techniques (inspection, auscultation and olfaction, inquiry, and palpation) forms the backbone of this platform. Modern AI technologies, combined with bioinformatics, are used to analyze large datasets of clinical diagnostic information, enabling real-time, precise monitoring of postoperative recovery. The platform supports the objectives of preventing disease, halting disease progression, and preventing recurrence by continuously monitoring patient health through wearable devices and AI-driven diagnostic tools. This integration allows for comprehensive, data-driven decision-making, moving beyond traditional, experience-based TCM practices.

Visualization of Perioperative Yin-Yang Status

The complexity of assessing Yin and Yang status during the perioperative period is addressed through digital tools that objectively measure autonomic function, such as HRV. HRV data can be used to track the balance between the sympathetic and parasympathetic nervous systems, reflecting the dynamic shifts between Yin and Yang. The use of these tools helps overcome the uncertainty inherent in traditional TCM diagnostic methods and provides a clearer, evidence-based framework for postoperative care.

Application of AI Biomarkers

The integration of AI biomarkers into the perioperative TCM platform represents a significant advancement in personalized medicine. These biomarkers, collected through wearable devices, provide continuous, non-invasive monitoring of a patient’s physiological states, reflecting the balance of Yin and Yang. AI biomarkers offer a cost-effective, modular approach to disease prevention, diagnosis, and treatment, enabling the detection of subtle changes in the body’s condition and facilitating more precise interventions.

Conclusions

The integration of TCM with modern digital technologies offers a promising pathway for optimizing postoperative recovery through a personalized, data-driven approach. By incorporating complexity science theories such as biological holography and chaos-fractal theory, the digital TCM platform provides a scientific basis for monitoring and adjusting perioperative care. AI-driven tools, wearable devices, and the quantification of Yin-Yang balance allow for precise management of postoperative recovery, improving patient outcomes and contributing to the evolution of integrated medicine. Moving forward, continued advancements in digital TCM platforms will help bridge the gap between traditional Chinese medicine and Western medical practices, creating a more holistic and effective approach to perioperative care.

Soaring insurance costs top concern for Floridians, FAU survey finds



Most Floridians worry about homeowners insurance, stronger hurricanes

More than two-thirds of Floridians are moderately or extremely concerned about hurricanes increasing in strength and frequency, according to a new Florida Atlantic University survey.

The Invading Sea’s Florida Climate Survey also found that most Floridians – 54% – are worried about being able to afford and maintain homeowners insurance due to climate change. According to a 2023 report by LexisNexis Risk Solutions, the average premiums for Florida homeowners rose nearly 60% between 2015 and 2023, the largest increase in any state.

“Floridians are connecting the dots between climate change and the damaging hurricanes and soaring insurance premiums that they’ve experienced in recent years,” said Colin Polsky, Ph.D., associate vice president of Broward campuses for FAU and a professor of geosciences in the Charles E. Schmidt College of Science.

The survey is the 12th conducted by the FAU Center for Environmental Studies on Floridians’ opinions about climate resilience issues since October 2019. The survey was renamed in 2024 after The Invading Sea, a website managed by the center that publishes news and commentary about climate-related topics.

The most recent survey found that 38% of Floridians were “extremely concerned” about hurricanes becoming stronger and/or more frequent, the highest percentage reporting the top level of concern since the survey started.

Another 29% were moderately concerned, 23% were slightly concerned and 10% weren’t concerned at all. The findings come in the wake of the destructive 2024 hurricane season, during which Florida was struck by Category 4 Hurricane Helene and Category 5 Hurricane Milton, fueled by record-high ocean temperatures.

The survey found that nearly two-thirds of Floridians (65%) believe that the state and federal governments should be doing more to address the impacts of climate change. Broken down by political party, 83% of Democrats support more government climate action – as do more than half of Republicans and more than 60% of independents.

“This majority support explains why despite continued anti-climate policy rhetoric from the Florida executive and legislative branches, we still see state action on climate adaptation,” Polsky said.

Most Floridians also support expanding the use of renewable energy. The survey found that 72% of Floridians agree that the state should diversify its energy generation to include more electricity produced from renewable sources.

Nearly two-thirds of Floridians support teaching climate science in K-12 schools, according to the survey. And 52% of respondents were more likely to support candidates who have a political record reducing the impacts of climate change.

The latter finding showed a large gap between political parties: Democrats (70%) were far more likely than independents (48%) and Republicans (39%) to express support for candidates who advance climate policy.

“This is now the second survey that we’ve asked Floridians whether they consider climate change when voting. Both surveys found that a majority of Floridians say they’re more likely to back candidates who address climate change, but we haven’t seen this translate at the ballot box,” Polsky said.

About 88% of all Floridians believe climate change is happening, the survey found. The finding is consistent with the results of all 11 previous surveys and higher than the 73% of Americans nationally who reported such an opinion in the latest edition of Yale polling on climate views across the country.

CES has conducted the survey since October 2019 and now does so every spring and fall. The latest edition was conducted in English and Spanish from March 5 to 7. The sample consisted of 1,400 Floridians, ages 18 and older, with a survey margin of error of +/- 2.53%. The data were collected using an online panel provided by GreatBlue Research. Responses for the entire sample were weighted to adjust for age, income, education, gender and region according to the 2023 U.S. Census Bureau’s American Community Surveys. It is important to remember that subsets carry higher margins of error.

A sustainable diet leaves room for two chicken breasts a week



We should eat less meat and more legumes, campaigns and dietary advice tell us. But how much is "less"? Researchers from DTU have an answer



Technical University of Denmark




We should eat less meat and more legumes, campaigns and dietary advice tell us. But how much is "less"? Researchers from DTU have an answer.

255 grams per week. That's the short answer to how much meat you can eat without harming the planet. And that only applies to poultry and pork.

Beef cannot be eaten in meaningful quantities without exceeding planetary boundaries, according to a scientific article published by a group of DTU researchers in the journal Nature Food. So says Caroline H. Gebara, postdoc at DTU Sustain and lead author of the study.

"Our calculations show that even moderate amounts of red meat in one's diet are incompatible with what the planet can regenerate of resources based on the environmental factors we looked at in the study. However, there are many other diets - including ones with meat - that are both healthy and sustainable," she says.

How much is ‘less’?

The researchers' first goal was to investigate whether it is even possible to fulfil the nutritional needs of the entire global population without exceeding planetary boundaries. According to the calculations, it is possible. But it will require a change in our food consumption on both a global and individual level, says Caroline H. Gebara.

"The global shift requires political action at the top level, while the individual shift will be much easier if we have better guidance and frameworks that support sustainable choices," she says.

The next goal of the research was therefore to come up with concrete figures for how much of different foods you can eat without consuming more of the earth's resources than it can regenerate, says Caroline H. Gebara.

"Most people now realise that we should eat less meat for both environmental and health reasons. But it's hard to relate to how much ‘less’ is and whether it really makes a difference in the big picture. Therefore, based on the planetary boundaries, we have calculated a concrete figure - 255 grams of poultry or pork per week - which you can actually visualise and consider when you are standing in the supermarket," she says.

In Danish supermarkets, a pack of two chicken breast fillets typically weighs 280 grams which is slightly over the limit of what one person can eat in a week without exceeding the planetary boundaries.

Not either-or

The research team's calculations take into account a number of environmental factors such as COemissions, the consumption of water and land use, as well as the health impact of a particular diet. In total, they have examined more than 100,000 variations of 11 types of diets and calculated their respective environmental and health effects.

And the calculations clearly show that a diet with even moderate amounts of red meat - beef or lamb, for example - exceeds planetary limits.

A pescetarian, vegetarian or vegan diet, on the other hand, is likely to stay within the limits of what the planet can support. But this also depends largely on the specific products included in the diets.

In addition, different combinations of diets, such as vegetarian but with dairy or eggs, can also be sustainable.

And that's exactly what Caroline H. Gebara hopes that the study will help more people realise: That a sustainable diet can take many different forms.

"For example, our calculations show that it's possible to eat cheese if that is important to you, while at the same time having a healthy and climate-friendly diet. The same is true for eggs, fish and white meat, but the premise is of course that the rest of your diet is then relatively healthy and sustainable. But it doesn't have to be either-or."

Facts

What are the planetary boundaries?

The nine planetary boundaries are scientifically based estimates of how much human impact the planet itself can compensate for.

For example, when humanity collectively consumes more freshwater than the planet is able to produce, we have breached the planetary boundary for freshwater consumption.

The nine planetary boundaries are:

1. Climate change

2. Loss of biodiversity

3. Freshwater use

4. Land area use

5. Emissions of ozone-depleting chemicals

6. Pollution with man-made substances

7. Release of aerosols into the atmosphere

8. Emissions of nitrogen and phosphorus

9. Loss of calcium carbonate in the ocean

Of the nine planetary boundaries, six have already been breached, according to a 2023 study by the Stockholm Resilience Centre, which first defined the boundaries in 2009. Only numbers five, seven and nine are still at a level that the planet itself is believed to be able to compensate for.


Doctors group files complaints, asks Oregon Health & Science University to shut down invasive reproductive experiment on primates



Move comes amid merger talks between OHSU and Legacy Health


 HALT PRIMATE TESTING FREE OUR RELATIVES


Physicians Committee for Responsible Medicine





PORTLAND, Ore. — The Physicians Committee for Responsible Medicine filed complaints with Oregon Health & Science University (OHSU), the United States Department of Agriculture, and the National Institutes of Health today, April 22, 2025, asking for an invasive reproductive experiment on nonhuman primates at Oregon National Primate Research Center to be shut down.

The study, which has received $525,000 from the NIH and will continue through August 2027, purports to investigate how chronic tetrahydrocannabinol (THC) use affects testicle size, sperm health, and male fertility.

For the experiment, the primates are given THC and put into restraint cages where researchers use electroejaculation to collect semen from them 18 times in 70 days.

“This experiment is a grotesque violation of both scientific ethics and animal well-being, said Janine McCarthy, MPH, science policy program manager for the Physicians Committee. “Forcing nonhuman primates into repeated restraint and electroejaculation to study the effects of THC on fertility is not only cruel—it’s scientifically unnecessary. We already know enough from human clinical studies to advise people against THC use to safeguard their reproductive health. Subjecting intelligent, social animals to this kind of suffering under the guise of research is indefensible,” she said.

The study violates the Animal Welfare Act’s mandate that experiments must assure that discomfort and pain to animals will be limited to that which is unavoidable for the conduct of scientifically valuable research, and the Public Health Service Policy’s requirement that replacement of animals be considered, the Physicians Committee complaints say.

The new complaints come as OHSU is attempting a merger with Legacy Health. Citing OHSU’s long history of federal Animal Welfare Act violations and useless experiments, the Physicians Committee, a national nonprofit with 17,000 doctor members, has been calling for OHSU’s primate research facility to be closed before an anticipated takeover of Legacy Health.

Recently, the Physicians Committee lauded a Community Review Board after it voted unanimously to reject the merger. A final decision will be made by the Oregon Health Authority’s Health Care Market Oversight Program, which was established by law in 2021 to review health care business deals and address the potential negative impacts of consolidation.

Founded in 1962, the primate research center, one of seven left in the United States, is located in Beaverton and houses more than 5,000 monkeys. Between 2014 and 2022, it violated the federal Animal Welfare Act more than 30 times. Records show pregnant monkeys have been injected with nicotine to damage their unborn babies, and in 2020, an employee scalded two monkeys to death in a washing system because he reportedly didn’t see them in the cage. More recently, in 2023, a 2-day-old monkey was crushed by a sliding glass door and had to be euthanized.

In late March, Gov. Tina Kotek asked leaders at OHSU to figure out how to close its primate research center.

Over 85% of more than 2,000 respondents polled in September 2024 in a Physicians Committee/Morning Consult survey agreed that animal-based research should be phased out in support of superior methods that do not use animals.

In contrast to animal experimentation, modern and versatile human-relevant methods, such as tissue chips, organoids, computational modeling, and high-throughput screening, have proven effective in drug development and disease modeling.

“Research must prioritize scientific rigor and humane methods,” McCarthy said, “and the ongoing reproductive experiment at OHSU fails on both counts. It’s time to move away from antiquated methods and invest in modern, human-specific science that respects both people and animals.”

Amazon research tackles £50 million parasite devastating fish farmers around the world



At the heart of the Amazon researchers are investigating a mysterious parasite which is devastating fish farms around the world


 News Release 
King's College London





At the heart of the Amazon researchers are investigating a mysterious parasite which is devastating fish farms around the world.

Parasites called myxozoa infect fish populations with deadly diseases, leading to severe losses in types of fish including salmon and trout. This loss of fish stock costs the fishing industry more than £50 million annually worldwide.

In the Amazon basin, home to one of the greatest diversities of fish, an international   team of scientists led by King’s College London and Universidade Federal de São Paulo (UNIFESP) have found more than 50% of all fish examined are infected by parasites. This threatens the livelihood of fish farmers, alongside biodiversity and recreational fishing. Elsewhere, some streams in western United States have lost 90% of their trout due to parasitic infection.

 

To find out more about these parasites, the team from King’s, UNIFESP, Federal University of Western Pará Brazil, University of Zagreb Croatia, University of Cambridge and Natural History Museum London set up a lab on a boat travelling along the Amazon Basin in Brazil where the Tapajós and Amazon Rivers converge, close to the city of Santarém, State of Pará.

They hope that investigating the different ways the parasites control their genes could hold the key to understanding the parasite and devising treatments.

Professor Paul Long, expert in marine biotechnology, Faculty of Life Sciences & Medicine, King’s College London, said: “We work in the Amazon because the diversity of life in the Amazon basin is undisputed and still little-known. This is especially true when it comes to parasites, which are hidden inside their hosts.

“Knowledge of parasites is fundamentally important for understanding the tree of life. How parasites co-evolve with their hosts and these complex relationships will influence biodiversity as well as ecosystem structure and function.

“To our surprise we uncovered a new process of gene regulation that was previously believed not to exist in these parasites. Fish farming is a key contributor to global food security.  Understanding how genes are turned on and off opens the opportunity to develop gene-based vaccines to control these economically significant fish pathogens.

Professor Edson Adriano, a parasitology expert from the Department of Ecology and Evolutionary Biology-UNIFESP, said: “The vast Amazon Basin is home to the largest diversity of freshwater fish in the world. This makes it a perfect setting to study fish parasites.

“Our discoveries about epigenetic processes in myxozoans open new avenues for understanding how the distinct conditions encountered by the parasite throughout its life cycle can affect genetic regulation. This becomes even more important when considering the impact scenarios predicted by climate change.”

Dr Santiago Benites de Pádua, a veterinarian and manager of Brazilian Fish Company, added: “Studies on these parasites are essential for developing strategies to control or reduce their impact on the health of farmed fish.”
