Countries across the world spend many billions of dollars every year subsidizing fishing that is environmentally damaging and unsustainable.

After years of tortuous negotiation under the auspices of the World Trade Organization (WTO), a global deal to reign in these subsidies emerged. The first part of this Agreement on Fisheries Subsidies finally entered into force this month, while a second part remains at the debate stage, held up by disagreements.

With consensus still lacking on crucial details, can these rules actually end subsidies that are contributing to overfishing across the world, and harming food supplies to some of the world’s most vulnerable people?

Dialogue Earth asked five experts for their views.

‘Fish populations finally have a chance to recover’

Megan Jungwiwattanaporn works on reducing harmful fisheries subsidies at The Pew Charitable Trusts

In the mid-1970s, 10% of fish stocks were fished at unsustainable levels. By 2021, that number had almost quadrupled to 37.7%. Subsidy-driven overfishing is depleting fish populations and hurting coastal communities who depend on a healthy ocean for their livelihoods and survival.

With the agreement now legally binding for the two-thirds of WTO member countries who have ratified it, fish populations finally have a chance to begin to recover.

And, as the WTO’s first sustainability-focused agreement, it paves the way for future multilateral treaties that protect the environment, and for broader fisheries reform at regional and country levels.

The agreement is also a step toward meeting one of the targets of the UN’s Sustainable Development Goals, which 193 countries adopted in 2015. As part of Goal 14, nations committed to reaching an agreement to end harmful fisheries subsidies.

But the work is not finished. Countries must implement the agreement by limiting some of the subsidies they give out that drive harmful practices. And WTO members must still finalize negotiations on additional rules that would end subsidies not included in the agreement: those that contribute to fishing in other countries’ waters and to overfishing and overcapacity, or a fleet’s ability to harvest more fish than is sustainable. Doing this will give fish populations an even better chance to recover.

‘‘Fish 2’ rules could bring even more progress’

The entry into force of the WTO agreement is a key milestone, and the next challenge will be to put these rules into practice effectively. But the story does not end there. WTO members are also negotiating a further set of rules, known as Fish 2, to make the agreement more comprehensive.

The current agreement, often referred to as Fish 1, targets specific situations where the harmful impacts of subsidies can be the most acute: illegal, unreported and unregulated fishing; overfished stocks; and unregulated high seas fisheries. Fish 2 aims to go further and prevent subsidies from contributing to overcapacity and overfishing in the first place. In other words, these further rules seek to better address the deep-seated and pervasive role of subsidies as a driver of unsustainable fishing.

As such, the impact of Fish 2 could be broader than Fish 1.

Talks on these additional rules advanced significantly and came close to conclusion in 2024, but progress has since slowed. It now appears unlikely that a final deal will be reached by the WTO’s 14th Ministerial Conference (MC14; March 2026). Still, the conference could play a critical role in injecting fresh momentum and steering negotiations toward a successful outcome. That should be the focus for WTO members at MC14.

‘Implementation is now key’

Daniel Skerritt is a senior analyst at the conservation NGO Oceana

With the agreement in force, attention turns from negotiation to implementation – at least for now. Starting 15 September, all ratifying members must comply with the Fish 1 rules: ending subsidies for illegal, unreported and unregulated fishing, fishing of overfished stocks, and unregulated high seas fishing. Equally important, members must now provide more complete and timely information on the scale, distribution and nature of their subsidy programs. This transparency is key to judging the successes – or failures – of Fish 1.

The agreement also empowers members to demand clarity from one another. For example, a country can request details about subsidies that support foreign vessels operating in its waters or ask for the scientific justification behind continued subsidization.

To support developing and least-developed countries, the newly launched Fish Fund will help build capacity for monitoring, reporting and compliance. This fund is important because it requires those providing the most subsidies to shoulder the greatest costs, ensuring the new commitments do not fall disproportionately on those least able to pay.

The clock has also started on the treaty’s four-year sunset clause. During this window, WTO members must agree to the more ambitious Fish 2 package, which is aimed at curbing capacity-enhancing subsidies that drive overfishing worldwide. Unfortunately, geopolitical headwinds have stalled talks and the vacant post of negotiation chair makes rapid progress unlikely. [The most recent chairperson, Iceland’s Einar Gunnarsson, stood down in July.]

Strong leadership from major economies, top subsidizers and coalitions such as the small island developing states and African, Caribbean and Pacific groups will be essential to keep momentum alive and deliver further meaningful reform.

‘This is a unique opportunity for Latin America, and for the ocean’

Andrea Michelson is regional coordinator of the Forum for the Conservation of the Patagonian Sea and Areas of Influence

The entry into force of the agreement marks a milestone on the road to better ocean governance and offers Latin America a unique opportunity to move towards better and necessary responsible management of marine resources.

Harmful subsidies not only endanger biodiversity and ecosystems, many of which are fragile, but also compromise the livelihoods, food security and economic resilience of the world’s most vulnerable coastal communities.

For countries in Latin America with vast coastlines and economies strongly linked to the sea, this is hugely important. On the one hand, it reinforces the role of regulations, transparency, regional commitment and an ecosystem approach. On the other hand, it opens up the possibility of redirecting and channelling financial resources towards responsible fishing and good practices.

Governments in the region must implement the agreement with commitment and dedication to the care of natural environments, coordinating efforts with all actors in the fishing sector, civil society and science. Only through multi-stakeholder engagement will this new regulatory framework translate into healthier, more resilient, equitable and productive oceans for present and future generations.

‘Significant implications for the world’s largest fisheries nation’

Zhang Yimo is the priority project coordinator of WWF China’s sustainable blue economy program

The entry into force of the agreement will have significant implications for China’s fisheries, particularly in enhancing the transparency of the nation’s subsidy policies.

The government has gained considerable experience in reforming fisheries subsidies in recent years. In 2021, it announced the abolition of fuel subsidies for fishing vessels. Instead, a new system was introduced in which only vessels that comply with certain conservation regulations can receive subsidies.

These “fisheries stewardship” subsidies in China still risk contributing to overcapacity and overfishing, according to a WWF report released last year. Under the existing framework, fishing vessel workers are not direct recipients of subsidies, and small-scale fishers receive significantly less support than those in the commercial sector. We recommend including vessel workers as subsidy recipients and ensuring income security for small-scale fishers, along with providing work-transition support for those who need to retire from fishing.

This is a significant year for China’s fisheries sector, as the country joined the Port State Measures Agreement and the WTO agreement, which it accepted in 2023, has come into force. These developments will strengthen China’s role in the global fight against illegal, unreported and unregulated fishing.

The WTO agreement coming into force encourages the global community to clarify many outstanding issues of harmful subsidies in fisheries – including who should receive subsidies and how to define overfishing.

Norwegian Rescue Diver Killed in Attempt to Save Young Girl

RS 125

Published Sep 28, 2025 11:16 PM by The Maritime Executive

 

 

The Norwegian sea rescue society Redningsselskapet reported Saturday that it has lost one of its own - a boat crew member who was killed while attempting a rescue in Norway's Lofoten archipelago.

On Friday afternoon, the rescue boat RS 125 (named "Det Norske Veritas") was called to respond to a fishing charter boat that had capsized in Nappstraumen, the waterway between the islands of Flakstadoya and Vestvagoya in Lofoten. On the distressed vessel, there were four adult tourists, two children and a fishing guide, all in need of rescue. 

Six people climbed up on the keep and were saved, according to NRK, but one young girl was still in the water. Rescue boat crewmember Adrian Willyson Brask (36) dived in to search for the last victim, and he tragically lost his life. The girl remains missing. 

"He died while performing the most important task a rescue boat crew can have - to try to save another life," said Grete Herlofson, general secretary of Redningsselskapet. "On a day like this, our thoughts go first and foremost to Adrian's family - his wife, his little daughter, his friends and colleagues - and to the family that still misses one of their own."

Brask's friends have set up a fundraiser for his family at https://www.spleis.no/project/453253.

RS 125 is a 22-meter rescue boat built in 2003. It was badly damaged in a rescue attempt in January 2024 when the crew tried to save a fisherman near Stamsund, Norway. The victim did not survive, and the rescue craft required a year in shipyard for repairs, supported by sponsor DNV. 

Back pain tied to higher rates of common diseases


The incidence of conditions such as heart disease, arthritis, diabetes and cancer is higher in people with back pain than in those without back pain



University of Technology Sydney



Back pain isn’t just a debilitating condition, it may be a flag for other major health issues. New research shows the incidence of conditions such as heart disease, arthritis, diabetes and cancer is higher in people with back pain than in those without back pain.

Chronic back pain is a leading cause of disability worldwide, and a major burden on healthcare systems and economies. It keeps millions of people from work and, for many, the simple act of sitting, standing or sleeping is a daily struggle.

The study, led by Associate Professor Rafael Zambelli Pinto, a physiotherapist and researcher specialising in musculoskeletal conditions from the University of Technology Sydney (UTS), was recently published in Brazilian Journal of Physical Therapy.

The international team also included researchers from the Universidade Federal de Minas Gerais, Universidade Estadual Paulista and University of Sao Paulo in Brazil and the University of Sydney, UNSW, NeuRA in Australia.

The study used data from the 2019 National Health Survey in Brazil, which covered nearly 90,000 people. Approximately one in five people reported chronic back pain, a finding similar to higher-income countries, indicating the research has global relevance.

It found that a range of diseases were more prevalent in people with chronic back pain than in those without chronic back pain.

Cardiovascular disease, arthritis and depression were the top three most prevalent comorbidities in people with chronic back pain. Diabetes, cancer, asthma and other lung diseases were also higher in this population than those without back pain.

Those with back pain were 17 per cent more likely to report cardiovascular disease, 15 per cent more likely to report arthritis, and 12 per cent more likely to have clinical depression than those without back pain.

Around four million Australians are estimated to be living with back problems, according to the Australian Institute of Health and Welfare, with nearly 3 in 4 of those with back pain aged over 45 classified as having a comorbidity.

Patients with chronic back pain who also have comorbidities are more likely to report severe activity limitations, particularly those who have arthritis, depression and cardiovascular disease, the research found.

“While more research is needed to understand the link between chronic back pain and other non-communicable diseases, they often share underlying risk factors such as physical inactivity, obesity, stress and poor sleep,” Dr Zambelli Pinto said.

“When these conditions occur together, the impact on daily life is significant. Adults with both back pain and arthritis, for example, are more than twice as likely to report serious limits on their ability to carry out everyday activities compared to those without this specific comorbidity,” he said.

Back pain is one of the most common reasons people visit their GP, and the study suggests a wider, more integrated approach to care could reduce suffering and ensure other chronic diseases are properly managed.

“The findings highlight the urgent need for doctors to look beyond pain management when treating patients with chronic back pain. It’s not just about the spine. These patients are carrying a heavier overall health burden that affects their independence and quality of life,” Dr Zambelli Pinto said.

The research suggests the need to develop comprehensive care pathways and interdisciplinary approaches to manage these patients effectively.

 

Low-cost drug shows promise for patients with life threating respiratory infections




King's College London






A widely available and affordable drug has been shown to be effective in treating seriously ill COVID-19 patients, according to a new international study led by researchers at the Australian National University (ANU) in collaboration with King’s College London.

The study analysed data from almost 500 patients hospitalised with COVID-19 across six countries. Patients who inhaled heparin were half as likely to require ventilation and had a significantly lower risk of dying compared with those receiving standard care.

Heparin, a drug traditionally injected to treat blood clots, was tested in this study in an inhaled form, targeting the lungs directly. As well as acting as an anticoagulant, heparin has anti-inflammatory and pan-antiviral properties. Earlier research results showed breathing and oxygen levels improved in COVID-19 patients after they inhaled a course of heparin.

The researchers believe the drug could also be useful in fighting other serious respiratory infections such as pneumonia.

Professor Clive Page, Emeritus Professor of Pharmacology at King’s who co-led the international study with ANU’s Professor van Haren, said: “Inhaled heparin is anti-viral, anti-inflammatory and anti-coagulant. There’s no other drug that has that unique combination. We know it’s only a matter of time until the next pandemic, and there are still COVID-19 patients who get very sick. This is a great weapon to have up our sleeve.”

While the findings highlight the potential of inhaled heparin, further development is required before the treatment can be routinely adopted. The researchers believe the drug could also be useful in fighting other serious respiratory infections such as pneumonia, which can be caused by a range of viruses and bacteria.

According to Professor van Haren, the drug would also be helpful for those with a compromised immune system, such as cancer patients, when they experience a respiratory infection.

Professor Frank van Haren, lead author, ANU and Director of the Intensive Care Unit at the St George Hospital in Sydney, said: “It doesn’t matter what kind of respiratory infection the patient is dealing with, the drug – when inhaled - will stop it from infecting the patient and from damaging the lungs. We’re aiming to conduct another trial in Europe to confirm its effectiveness in fighting other common respiratory infections such as influenza and RSV. And because it’s inexpensive, it’s much more accessible for those from low-income countries"

The researchers are now also developing an improved formulation of heparin, specifically designed to be given by inhalation.

The research is published in eClinicalMedicine and simultaneously presented of at the European Respiratory Society (ERS) International Congress in Amsterdam on Sunday 28 September, the leading annual gathering for respiratory research.

A team led by UCL (University College London) and Imperial College London researchers has shown for the first time how life-saving antibiotics called polymyxins pierce the armour of harmful bacteria.

The findings, published in the journal Nature Microbiology, could lead to new treatments for bacterial infections – especially urgent since drug-resistant infections already kill more than a million people a year.

Polymyxins were discovered more than 80 years ago and are used as a last-resort treatment for infections caused by “Gram negative” bacteria. These bacteria have an outer surface layer that acts like armour and prevents certain antibiotics from penetrating the cell. Polymyxins are known to target this outer layer, but how they disrupt it and then kill bacteria is still not understood.

In the new study, the research team revealed in high-resolution images and biochemical experiments how the antibiotic Polymyxin B rapidly caused bumps and bulges to break out on the surface of an E. coli bacterial cell.

These protrusions, which appeared within minutes, were followed by the bacterium rapidly shedding its outer armour.

The antibiotic, the researchers concluded, had triggered the cell to produce and shed its armour. The more the cell tried to make new amour, the more it lost the amour it was making, at such a rate that it left gaps in its defences, allowing the antibiotic to enter the cell and kill it.

However, the team found that this process – protrusions, fast production and shedding of armour, and cell death – only occurred when the cell was active. In dormant (sleeping) bacteria, armour production is switched off, making the antibiotic ineffective.

Co-senior author Dr Andrew Edwards, from Imperial, said: “For decades we’ve assumed that antibiotics that target bacterial armour were able to kill the microbes in any state, whether they’re actively replicating or they were dormant. But this isn’t the case. Through capturing these incredible images of single cells, we’ve been able to show that this class of antibiotics only work with help from the bacterium, and if the cells go into a hibernation-like state, the drugs no longer work - which is very surprising.”

Becoming dormant allows bacteria to survive unfavourable conditions such as a lack of food. They can stay dormant for many years and “wake up” when conditions become more favourable. This can allow bacteria to survive against antibiotics, for instance, and reawaken to cause recurrent infections in the body.

Co-senior author Professor Bart Hoogenboom, based at the London Centre for Nanotechnology at UCL, said: “Polymyxins are an important line of defence against Gram-negative bacteria, which cause many deadly drug-resistant infections. It is important we understand how they work.

“Our next challenge is to use these findings to make the antibiotics more effective. One strategy might be to combine polymyxin treatment – counterintuitively – with treatments that promote armour production and/or wake up ‘sleeping’ bacteria so these cells can be eliminated too.

“Our work also shows we need to take into account what state bacteria are in when we are assessing the effectiveness of antibiotics.”

The E. coli cells were imaged at the London Centre for Nanotechnology at UCL. A tiny needle, only a few nanometres wide, was run over the bacterial cell, “feeling” the shape to create an image (a technique called atomic force microscopy) at much higher resolution than would be possible using light.

Co-author Carolina Borrelli, a PhD student at the London Centre for Nanotechnology at UCL, said: “It was incredible seeing the effect of the antibiotic at the bacterial surface in real-time. Our images of the bacteria directly show how much polymyxins can compromise the bacterial armour. It is as if the cell is forced to produce ‘bricks’ for its outer wall at such a rate that this wall becomes disrupted, allowing the antibiotic to infiltrate.”

The team compared how active (growing) and inactive E. coli cells responded to polymyxin B in the lab, finding that the antibiotic efficiently eliminated active cells but did not kill dormant cells.

They also tested the E. coli cells’ response with and without access to sugar (a food source that wakes up dormant cells). When sugar was present, the antibiotic killed previously dormant cells, but only after a delay of 15 minutes – the time needed for the bacteria to consume the sugar and resume production of its outer armour.

In conditions where the antibiotic was effective, the researchers detected more armour being released from the bacteria. They also observed the bulges occurring across the surface of the cell.

In conditions where it was ineffective, the antibiotic bound itself to the outer membrane but caused little damage.

Co-author Dr Ed Douglas, from Imperial, said: “We observed that disruption of the outermost armour of the bacteria only occurred when the bacteria were consuming sugar. Once we knew that, we could quickly figure out what was happening.”

Co-author Professor Boyan Bonev, of the University of Nottingham, said: “Working together has given us unique insights into bacterial physiology and morphology under stress that have remained hidden for decades. Now we understand better the weak points of bacteria.”

MEDICAL FALSE IMPRISONMENT PAYS BILLS

Patients with intellectual and developmental disabilities substantially over-represented among long-stay psychiatric inpatients





Institute for Clinical Evaluative Sciences





Toronto, ON, September 29, 2025 – Individuals with intellectual and developmental disabilities (IDD) account for more than one in five patients who have been in Ontario’s mental health beds for over a year, according to a new study from researchers at ICES and the Centre for Addiction and Mental Health (CAMH).

The findings suggest that people with IDD have different support needs compared with patients without IDD as they are more likely to have moderate or severe cognitive impairment, difficulty caring for themselves, and few social supports, which may contribute to challenges transitioning out of hospital and into the community. Enhancing specialized supports both in hospital and in the community could reduce their length of stay and admission rates.

“We know what is needed for successful transitions and we have published Ontario Practice Guidance on how to do this well,” says Avra Selick, lead author and scientist within the Azrieli Adult Neurodevelopmental Centre at CAMH. “There are amazing champions out there working hard to support these transitions, but we urgently need to build capacity in the hospital, community and health and social services sectors to work together to achieve widespread change.

Key findings:

  • Of the 1,466 patients in Ontario mental health beds for over a year on September 30, 2023, 322 were people with IDD.
  • Compared with inpatients without IDD, a higher proportion of those with IDD were younger and had a psychotic disorder. Almost 40 per cent of these individuals were autistic.
  • Patients with IDD were more likely to be physically restrained or experience seclusion in hospital, and only five per cent were in specialized units for people with IDD. The remainder were in other psychiatric units where providers were not trained to work with them.
  • More than half of long-stay patients with IDD lacked social or familial connections to support their discharge from hospital.

The authors recommend increasing capacity and developing the expertise of providers within hospital settings to deliver appropriate care for patients with IDD. They also recommend enhancing outpatient mental health services, housing, and disability-related supports in the community. These strategies can prevent unnecessary hospitalizations, reduce length of stay and support successful transitions back into the community.

Resources on how to support transitions out of hospital for patients with IDD are available through the H-CARDD program led out of CAMH.

“Adults with IDD make up a substantial proportion of long-stay admissions in units that were not designed to meet their needs, with very few hospital staff trained to support this population,” says Yona Lunsky, ICES scientist and Director of the Azrieli Centre at CAMH. “We need to invest in improving their care once they are in hospital while also addressing the challenges that lead to these lengthy hospitalizations in the first place.”

Many older adults – especially Gen X women – show signs of addiction to ultra-processed foods



Adults age 50 to 80 who meet criteria for an addiction to ultra-processed foods are far more likely to report being overweight, or beng in fair or poor mental or physical health




Michigan Medicine - University of Michigan





They were the first generation of Americans to grow up with ultra-processed foods all around them – products typically loaded with extra fat, salt, sugar and flavorings. They were children and young adults at a time when such products, designed to maximize their appeal, proliferated.

Now, a study shows, 21% of women and 10% of men in Generation X and the tail end of the Baby Boom generation, now in their 50s and early 60s, meet criteria for addiction to these ultra-processed foods.

That rate is far higher than it is among adults who grew up just a decade or two earlier, and only encountered ultra-processed foods in adulthood. Among adults age 65 to 80, just 12% of women and 4% of men meet criteria for ultra-processed food addiction.

The study, published in the journal Addiction by a team from the University of Michigan, is based on nationally representative data from more than 2,000 older Americans surveyed by the U-M National Poll on Healthy Aging.

The poll is based at the U-M Institute for Healthcare Policy and Innovation and supported by Michigan Medicine, U-M’s academic medical center. The new paper builds on a previous poll report by diving deeper into generational differences and correlations with health.

Measuring food addiction in an under-studied group

The researchers used the modified Yale Food Addiction Scale 2.0 (mYFAS 2.0), a standardized tool adapted from the criteria used to diagnose substance use disorders. The scale asks about 13 experiences with ultraprocessed foods and drinks that define addiction, such as strong cravings, repeated unsuccessful attempts to cut down, withdrawal symptoms, and avoiding social activities because of fear of overeating.

In this case, the “substance” is not alcohol or nicotine, but highly rewarding ultra-processed foods such as sweets, fast food, and sugary beverages. By applying clinical addiction criteria to ultra-processed foods, the study highlights the ways in which such foods can “hook” people.

“We hope this study fills a gap in knowledge about addiction to ultra-processed foods among older adults, as measured by a well-studied and standardized scale,” said Lucy K. Loch, a graduate student in the U-M Department of Psychology. “Today’s older adults were in a key developmental period when our nation’s food environment changed. With other research showing clear links between consumption of these foods and risk of chronic disease and premature death, it’s important to study addiction to ultra-processed foods in this age group.”

Differences by gender

Unlike traditional substance use disorders — which historically have been more common in older men — ultra-processed food addiction shows the opposite pattern: higher prevalence in older women.

One explanation may be the aggressive marketing of “diet” ultra-processed food to women in the 1980s.

Low-fat cookies, microwaveable meals, and other carbohydrate-heavy products were promoted as weight-control solutions, but their engineered nutrient profiles may have reinforced addictive eating patterns.

Women now aged 50 to 64 may have been exposed to ultraprocessed foods during a sensitive developmental window, which may help explain the poll’s findings for this age group, said senior author Ashley Gearhardt, Ph.D., a professor of psychology at U-M and member of IHPI. Gearhardt leads the U-M Food and Addiction Science & Treatment Lab.

“The percentages we see in these data far outpace the percentages of older adults with problematic use of other addictive substances, such as alcohol and tobacco,” said Gearhardt. “We also see a clear association with health and social isolation, with much higher risks of ultra-processed food addiction in those who call their mental or physical health status fair or poor, or say they sometimes or often feel isolated from others.”

Key findings related to overweight, health status and social isolation

  • Overweight self-perception:
    • Women aged 50 to 80 who said they are overweight were more than 11 times as likely to meet criteria for ultra-processed food addiction than women who say their weight is about right. Men who reported being overweight were 19 times as likely.
    • No matter what their age, 33% of women who described themselves as overweight, 13% of women who described themselves as slightly overweight and 17% of men who described themselves as overweight met criteria for addiction to ultra-processed foods. Of the total sample, 31% of women and 26% of men in the sample said they were overweight and 40% of women and 39% of men said they were slightly overweight.
  • Health status:
    • Men reporting fair or poor mental health were four times as likely to meet criteria for ultra-processed food addiction; women were nearly three times as likely.
    • For physical health, men reporting fair or poor health were three times as likely to meet criteria for ultra-processed food addiction, and women were nearly two times as likely.
  • Social isolation: Men and women who reported feeling isolated some of the time or often were more than three times as likely to meet criteria for ultra-processed food addiction as those who did not report isolation.

The researchers suggest that individuals who perceive themselves as overweight may be particularly vulnerable to “health-washed” ultra-processed foods – those marketed as low-fat, low-calorie, high-protein or high-fiber, but still formulated to amplify their appeal and maximize craving.

“These products are sold as health foods – which can be especially problematic for those trying to reduce the number of calories they consume,” Gearhardt said. “This especially affects women, because of the societal pressure around weight.”

Looking Ahead

The generation of older adults now in their 50s and early 60s is the first to live most of their lifespan in a food environment dominated by ultra-processed foods, Geahardt noted.

“These findings raise urgent questions about whether there are critical developmental windows when exposure to ultra-processed foods is especially risky for addiction vulnerability,” she said. “Children and adolescents today consume even higher proportions of calories from ultra-processed foods than today’s middle-aged adults did in their youth. If current trends continue, future generations may show even higher rates of ultra-processed food addiction later in life.”

She added, “Just as with other substances, intervening early may be essential to reducing long-term addiction risk across the lifespan.”

The study was funded by a National Science Foundation Graduate Research Fellowship Program (DGE-2241144) and the National Institute on Drug Abuse of the National Institutes of Health (5R01DA055027).
