The Department of Energy and Environmental Protection Agency have awarded $326 million to three Colorado State University research projects that aim to improve U.S. oil and gas operations and reduce methane emissions nationwide.

The EPA’s Methane Emissions Reduction Program is providing the funding to the CSU Energy Institute and faculty working across multiple departments in the Walter Scott, Jr. College of Engineering, with the goal of helping oil and gas operators improve operational efficiency and manage emissions. The efforts will also support activity to build an inventory of methane emissions, improve air quality and offer workforce development.

The combined funding amount constitutes one of the largest federal award packages in the university’s history and will enable high-impact research, CSU Vice President for Research Cassandra Moseley said.

“We are proud to lead deployment of innovative solutions to emissions that will support small operators, contribute to workforce development and improve conditions for communities. This work will be accomplished at a massive scale,” Moseley said.

“CSU interdisciplinary research has provided solutions in this space for decades, and I look forward to seeing what these new partnerships – involving industry, the environmental community and local stakeholders – can accomplish in the future.”

Natural gas is widely seen as a bridge fuel to low-carbon energy. However, it is made primarily of methane – a powerful greenhouse gas contributor – which can escape from production, storage and transport systems, so even small natural gas leaks can reduce its benefit as an alternative fuel source. Additionally, methane is often co-emitted with other air pollutants that create ozone and air-quality impacts in local communities.

Researchers at CSU have been working for over 30 years to develop and implement solutions to such problems through the Energy Institute, headquartered at the Powerhouse Energy Campus.

One such example is the Methane Emissions Technology Evaluation Center (METEC), a large-scale facility where researchers collaborate with oil and gas industry partners and solution developers to create best practices in emissions leak detection, technology and training. METEC will lead two of the newly funded projects.

Dan Zimmerle, director of METEC, will lead research on the first of the three awarded projects, which will implement new mitigation technology at older, lower producing wells that have disproportionately high methane emissions.

“The project will develop a funding program that provides cost-effective mitigation solutions for these companies,” Zimmerle said.

The sites – known as marginal convention wells – often lack operational capabilities found at newer sites and belong to smaller operators with staff and capital limitations that can slow implementation of mitigation solutions.

“We know these solutions work and are effective. We want to make it as easy as possible for operators with less than $40 million in revenue and small staffs to implement them,” Zimmerle said.

The second funded project is also a METEC project and will develop a national methane emissions inventory.

Research Scientist Anna Hodshire will lead that work and said her team will develop a comprehensive emissions inventory across production basins in eastern Colorado, Wyoming and seven other states. The CSU team will assist in two other regions; ultimately, CSU will be involved in inventory development in 32 states that produce the vast majority of U.S. natural gas.

“METEC holds a unique position as a neutral third party that works with all the stakeholders in this space – including companies, local communities, the environmental community, regulators, training organizations and non-governmental organizations,” said Hodshire who is also an associated faculty member with the Department of Systems Engineering. “This project continues that role and further elevates us as a national resource for reducing emissions.”

The third funded project will be conducted primarily in the field and will work with a leading manufacturer of energy systems to co-develop and demonstrate solutions for methane emission reduction from natural gas engine-compressor sets. Professors Daniel Olsen and Bret Windom in the Department of Mechanical Engineering and Timothy Vaughn at the Energy Institute will lead this work.

Olsen said the goal of the project is to reduce engine methane emissions by up to 90%.

“We are uniquely positioned to accomplish that thanks to our extensive experience and a long history of field studies and work with companies producing and using natural gas equipment,” he said.

The Energy Institute will organize and house the research and engagement activity associated with the award and continue its work bringing together researchers from across CSU’s campus.

Bryan Willson founded CSU’s Engines & Energy Conversion Laboratory and its Powerhouse Energy Campus in 1992, which paved the way for the Energy Institute, where he serves as executive director.

Throughout his career, Willson has worked to build bridges between industry and the environmental community in a variety of fields in the U.S. and globally and has founded several global companies that provide solutions to complex emissions challenges. He shared the importance of the university’s impartial leadership role to work across sectors in quantifying and reducing the environmental impacts from natural gas production and use.

“These projects will reduce climate emissions by hundreds of millions of tons, improve air quality and provide jobs in local communities, support small production companies and support national goals in energy independence,” Willson said.

Research assesses how infertility treatments can affect family and work relationships



Study involved 242 couples living in the Metropolitan Region of São Paulo (Brazil); men showed higher levels of work-family conflict, while women were more affected by stress.




Fundação de Amparo à Pesquisa do Estado de São Paulo




Infertility is a problem that affects between 8% and 12% of couples of reproductive age worldwide – for some of them, the problem interrupts a life project, which is the desire to have children and build a family. Advances in technology and medicine have made assisted reproductive treatments possible, but they can be physically and psychologically draining for the couples involved, especially because of expectations of results that may not be achieved.

The emotional impact of treatment is well documented in the scientific literature. Frustration with negative results has an impact on the psychological and social well-being of the couple, who may develop symptoms such as depression, anxiety, anger and stress, thus worsening their quality of life. Now, for the first time, a study supported by FAPESP and carried out at the ABC Medical School (FM-ABC) in Santo André, a municipality in the Metropolitan Region of São Paulo (MRSP), in Brazil, has examined work-family conflicts in these patients, which can be associated with frequent absences due to medical appointments or tests, for example.

The results, published in the journal Psychology, Health & Medicine, indicate that levels of work-family conflict are higher among men, while stress affects women more.

A total of 242 couples undergoing assisted reproductive treatment at the Ideia Fértil Institute, linked to the FM-ABC, in the MRSP, were studied. Among the participants, the median age was 37 years; 60% were women; 67% had a university degree; 37% had been married for more than ten years, 26% for between five and ten years, and 37% for five years or less.

In most cases, assisted reproductive treatments require time and large financial investments, which can be stressful for working patients. However, the scientific literature lacks data on the impact of this procedure on work-family conflicts.

“Infertile patients undergoing treatment can risk losing their jobs due to frequent absences for medical appointments and tests. For example, it’s common for a woman to ask for a medical certificate without the clinic’s logo so that her employer doesn’t know she’s trying to get pregnant,” says Victor Zaia, professor in the Postgraduate Program in Health Sciences at the FM-ABC and lead author of the study.

In addition, these patients may also experience reduced productivity, difficulty concentrating, challenges in managing medication side effects, and difficulties with time management. “Work-family conflict occurs when these individuals experience tension as they try to fulfill their professional and personal responsibilities. Many experience stress, fatigue, emotional exhaustion, sleep disturbances, dissatisfaction, marital problems, and decreased productivity. The result can be conflicts between these roles, with physical and psychological consequences.”

Evaluation scales

To arrive at the results, the researchers used online questionnaires to assess the couples. They answered questions from four internationally validated scales: Infertility-Related Stress Scale-Brazil (IRSS); Connor-Davidson Resilience Scale 10 (CD-RISC 10); Perceived Social Support Scale (PSSS); and Work-Family Conflict Scale.

On the Infertility-Related Stress Scale, the volunteers answered 12 questions about interpersonal stress (how infertility situations would disrupt the person’s daily life with friends, family, spouse) and questions about intrapersonal stress (how much the infertility problem affects their physical and emotional well-being).

On the Resilience Scale, the participants answered ten questions about their ability to adapt to life’s changes; about overcoming difficulties after illness or other problems; and about being able to think clearly when under pressure, among others.

The difference in this case, Zaia explains, is that the research focused on something that was happening at the time – the assisted reproductive treatment – whereas many studies on resilience ask about something that has already happened in the past, looking for memories. “In our study, people were starting reproductive treatment. So the impact, the risky situation, was being experienced in the now.”

The third tool used in the survey was the Perceived Social Support Scale, which, as its name suggests, is a 29-question scale designed to understand whether the participant receives and perceives any type of emotional or practical support from their spouse, family, and friends.

Finally, the researchers applied the Work-Family Conflict Scale – the most important in the study. It aims to assess the interference between the family and work environments within two sub-scales: Work Interference in the Family and Family Interference in Work.

In the analyses, the male participants showed greater resilience and lower levels of stress, both intrapersonal and interpersonal, compared to the women undergoing infertility treatment. However, the male patients reported higher levels of work interference in the family. In addition, there were significant differences in work-family conflict based on the couple’s income: those with higher incomes reported more interference.

On the other hand, the study found that women undergoing infertility treatment had lower levels of resilience and higher levels of stress, which the authors suggest may be explained by societal expectations about motherhood, which is considered a central role for women. The researchers also found significant correlations between resilience and emotional support, intrapersonal stress, and interpersonal stress.

“Stress alone doesn't explain work-family conflict. But we concluded that if a person has more stress, little social support and less resilience, they’ll most likely have higher levels of conflict. And if they can’t manage those conflicts, they’ll probably have more stress, leading to a kind of vicious circle,” Zaia explains.

From a clinical practice standpoint, Zaia says, these findings can guide health professionals in working with couples to reinforce strategies to improve and strengthen aspects of resilience and emotional support. “All the issues are important. This couple is suffering. We need to improve communication and support, as well as working on stress management strategies so that they can better adapt to treatment,” the researcher explained. 

According to Zaia, there are two ways to try to overcome these conflicts: resilience (which is the ability to adapt to significant changes in life) and social support. Resilience is considered a protective factor because it can moderate the relationship between stress and quality of life, reducing the possible negative effects of stress related to infertility. And social support, in turn, helps because being surrounded by people who provide emotional and practical support can reduce the affective burden of infertility and possibly ease the challenges of treatment.

Assisted reproduction

Infertility is defined as the inability to get pregnant after at least one year of regular unprotected intercourse. Assisted reproductive treatments are available, but they are time-consuming and costly. There are few services in the Sistema Único de Saúde (SUS, Brazil’s national public health network) that offer this treatment – and they are very restrictive (imposing age limits, for example).

A report by the United Nations Population Fund (UNFPA) in Brazil, published in March 2024, points out that Brazil has 192 assisted reproduction clinics, of which only 11 are public (6%). In 2023, the cost of a complete IVF cycle varied between BRL 15,000 and BRL 100,000, depending on the number of attempts, the procedure used and the location of the clinic. The clinic involved in the study is a social organization and the patients treated there pay only the cost of the treatments, which start at BRL 3,000.

Smaller fish offer better nutrition, lower environmental cost



Cornell University




ITHACA, N.Y. – Smaller fish species are more nutritious, lower in mercury and less susceptible to overfishing, a Cornell University-led research team has found.

The team’s study, published in One Earth, was conducted in the Amazon River, but the findings have implications for biodiversity conservation and public health across the globe as large fish species populations decline worldwide.

“Fish can provide a nutritious source of food at lower environmental cost than other animal-sourced foods, but fish can also potentially expose consumers to mercury contamination, and overexploitation of oceans and rivers harms biodiversity,” said first author Sebastian Heilpern, a Schmidt AI in Science Postdoctoral Fellow in the College of Veterinary Medicine.

The researchers analyzed nutritional value, mercury content, price and abundance for 59 fish species in the Amazon River. They found that smaller species that are more common and less expensive are also more nutritious and lower in mercury. 

Worldwide, larger fish species tend to have the highest levels of mercury, because the element accumulates in their tissues as they live longer and eat other mercury-contaminated organisms. The problem is especially acute in the Amazon because of the expansion of poorly regulated gold mining that uses mercury to separate gold from river sediments.

The Amazon is one of the most biodiverse regions in the world. Roughly 2,500 species of fish exist in the Amazon River, and about 100 different species are sold for consumption, Heilpern said. Helping people get the best nutrition from limited resources is a key priority, especially as population growth and climate change put even more pressure on natural resources, he said.

Though this research was conducted in the Amazon, many findings are more broadly applicable. For example, though humans tend to prize larger fish species, for cultural reasons and easier preparation, globally, larger fish have higher mercury levels and are more vulnerable to human pressures. Larger species such as goliath catfish, tuna and salmon are more likely to take long migratory routes; especially for freshwater species, these routes can be interrupted by dams and other habitat interruptions that further jeopardize reproduction.

Smaller fish are less susceptible to overfishing, in part because they have faster reproduction cycles, which may also make them more nutritious because micronutrients like iron and zinc fuel cell metabolism and growth, Heilpern noted.

Public health messaging should incorporate a more holistic view of the nutritional and environmental impacts of eating a variety of fish, the researchers advocate.

“Human food systems are a huge driver of biodiversity loss in the environment. At the same time, biodiversity in our food systems sustains the nourishment that humanity depends upon,” Heilpern said. “My hope is that this information can help provide guidance and identify solutions so that our food systems can become more sustainable, for the benefit of human health and ecological systems.”

Building sentence structure may be language-specific

Do speakers of different languages build sentence structure in the same way? In a neuroimaging study published in PLOS Biology, scientists from the Max Planck institute for Psycholinguistics, Donders Institute and Radboud University in Nijmegen recorded the brain activity of participants listening to Dutch stories. In contrast to English, sentence processing in Dutch was based on a strategy for predicting what comes next rather than a ‘wait-and-see’ approach, showing that strategies may differ across languages.

While listening to spoken language, people need to link ‘abstract’ knowledge of grammar to the words they actually hear. Theories on how people build grammatical structure in real time are often based on English. In sentences such as ‘I have watched a documentary’, the noun ‘documentary’ immediately follows the verb. However, in Dutch sentences, the word order may be reversed: ‘Ik heb een documentaire gezien’ (‘I have a documentary watched’).

To find out whether speakers of different languages build grammatical structure in the same way, it is important to look at languages that differ from English in such interesting respects”, says first author Cas Coopmans. “Findings based on English may not generalise to languages that have different grammatical properties, such as Dutch.”

Audiobook stories

To investigate how people build sentence structure in Dutch, the researchers measured the brain activity of 24 participants who listened to Dutch audiobook stories in a magnetoencephalograophy (MEG) scanner.

For every word in the audiobook, the researchers determined how much grammatical information could be built. A ‘top-down’ strategy based on early prediction of upcoming sentence structure was compared to a ‘bottom-up’ strategy, based on integrating grammatical information at a later stage.

Predicting what comes next

Both sentence building strategies could predict activity in the major left hemisphere’s language areas. But the effects were much stronger for predictive structure building.

While speakers of English seem to adopt a ‘wait-and-see’ approach, speakers of Dutch are more likely to build sentences in a predictive manner. This means that speakers of different languages differ in how they build grammatical structure during language comprehension.

The researchers next want to apply this method to study other languages, as well as the role of different linguistic properties. “Now that we know that we can use this method to study how people build grammatical structure during naturalistic spoken language comprehension, we can see how this process is influenced by other linguistic properties. In future work, we will investigate how the brain might use the prosodic properties of speech to extract the grammatical structure of spoken sentences”, says Coopmans.
