Promoting the acquisition of the host country's language is crucial for integrating immigrants into society, as it fosters social harmony, economic contribution, and mutual understanding among the citizens. With an increase in Japan’s foreign resident population, supporting their integration into local communities is a major issue. However, in Japan, many municipalities, instead of hiring professional language teachers, rely on volunteers to provide language instructions.

Exploring the issue, Associate Professor Bettina Gildenhard from the Faculty of Global Communications, Doshisha University, conducted a study to investigate how volunteer-led Japanese language classes work within broader policy frameworks and everyday community settings. While previous research has often examined language policies and teaching practices separately, this study serves as a link between both. It examines the tensions between personal initiatives, national language policies, and the quest for professionalism that shape the microcosm of local Japanese classes run by volunteers. The findings were made available online in the journal Japan Forum on April 24, 2026.

The study used two approaches: a review of the top-down language policy process through an analysis of published documents and an in-depth examination of the actual process through practical research. Government documents show that since the early 2000s, national and local policies have increasingly incorporated volunteers into providing formal language education, despite limited investment in professional teaching positions. Additionally, the research also draws in participant observation, interviews with volunteers, and reflection on training programs, thus providing a comprehensive view of both top-down policies and on-ground realities.

The author’s personal motivation also plays an important role in shaping this research. Her involvement in volunteer language support arose from a desire to better understand the multicultural coexistence and integration of foreign residents. Her direct participation in these classes proved to be more effective in critically reflecting upon the role of volunteers themselves.
What began as an effort to support language learning gradually became an opportunity to question how volunteers are positioned within the system,” she explains.

A key concept observed was “semi-professionalism.” Training programs in Japan are designed to improve teaching quality while preparing volunteers to take on a more structured, professional-like role. In this context, volunteers function as “quasi-professionals,” meaning they are not formally certified teachers but are trained and expected to deliver lessons with a similar level of responsibility and consistency. Many volunteers enjoy teaching, and many migrants also expect to be taught by “teachers.” When too much emphasis is placed on formal language instruction, however, migrants are mainly viewed as non-native speakers rather than as fellow community members. Similarly, volunteers who enjoy engaging with foreign residents and wish to develop new activities might be pushed into a teaching role they do not wish to assume.

Overall, the research highlights internal debates regarding teaching methods and professionalism between volunteers and demands for a more bala    nced approach. It suggests increasing investment in professional language educators along with continued support for volunteer initiatives. It also reflects on recognizing the value of volunteers while also addressing structural gaps, which can help create a more effective and diverse system. Thus, aligning policy with practice and community engagement can prove to be essential in supporting foreign residents as active participants in Japanese society.

Can Europe get “energy-connected”? Brookings report examines EU’s efforts to become more self-reliant




Energy integration could strengthen security, sustainability



Brookings Institution






As European countries navigate an increasingly complex and chaotic geopolitical environment, energy security has shot up to the top of their political priorities. Across the continent, energy security is now clearly recognized as an essential public good. And the latest geopolitical upheavals, including Russia’s invasion of Ukraine, the Iran War, and a more coercive and unpredictable United States, have made it clear to European leaders that they must move swiftly and forcefully to ensure that the continent’s energy supplies remain secure, sustainable, and affordable.

In a new report, Brookings experts Samantha Gross and Constanze Stelzenmüller examine how a more integrated European energy system could strengthen energy security, while also furthering sustainability and affordability.

“Europe’s new energy troubles provide a compelling logic for solidarity and collective action,” said Stelzenmüller, the director of the Center on the United States and Europe. “The costs will be high—but the cost of inaction will be even higher.” 

According to Stelzenmüller and Gross, the director of the Energy Security and Climate Initiative, European energy integration holds enormous promise and could help significantly boost the continent’s transition to clean energy. A more energy-connected Europe would help individual countries deal with energy disruptions and shortages. When these disruptions occur, cross-border transfers from neighboring states can ease supply and price shocks. This strategy is already being used in Ukraine and elsewhere.

 Greater integration will also enable more efficient management of intermittent renewable electricity sources such as solar and wind. As more demand is met by less expensive sources from across the continent, overall energy costs will drop.

Despite this promise, the authors note that there are significant economic and political challenges to integration. Building and modernizing infrastructure such as transmission lines and pipelines will require major funding from the EU and individual member states, as well as private funding. The costs will run into the hundreds of billions of dollars, at least, and will likely lead to questions about who should pay for what. Each country will have to give up some control of its energy system, which could be politically and logistically difficult.

Moreover, while integration will almost certainly lower overall energy costs, not every consumer will be better off all the time. And some energy producers may balk at facing new competition from less expensive sources of energy elsewhere in Europe. These questions may create constituencies that oppose further integration.

Until recently, European countries focused on ensuring that they had reliable ways to import fuel as they made the transition to renewables. In 2023, the EU imported 58% of its fuel (oil, natural gas, and coal), a level that has been largely consistent over the last 20 years. But as the global energy situation has become more tenuous, the continent has increasingly turned its attention to autonomy and internal cooperation.

A key turning point was Russia’s 2022 invasion of Ukraine, which led to Russia drastically reducing its exports of natural gas supply to Europe. Since Russia invaded Ukraine in 2022, the EU has worked to eliminate its reliance on Russian gas. Progress so far has been impressive: a 45% share of imports from Russia in 2021 declined to a 19% share in 2024. The EU plans to eliminate the import of all Russian gas by the end of 2027. And in December 2025, the European Commission released the European Grids Package, an ambitious plan to implement the free flow of electricity across borders. The EU is particularly focusing on expanding renewable energy production in areas that are especially suited to it, including solar energy in Spain and wind energy in the North Sea.

The EU estimates that electricity market integration already saves consumers about $40 billion a year, and that greater integration could increase this to $50 billion by 2030. Another benefit: by lowering energy costs for business, integration can boost European competitiveness.

“For Europe, these efforts can be a win-win-win,” says Gross. “It will strengthen its energy security while at the same time moving more toward renewables and lowering overall energy costs in the long term.”

A Korean research team has successfully developed a technology that converts carbon dioxide (CO₂) into liquid hydrocarbons such as gasoline and naphtha, achieving pilot-scale production of 50 kg per day.

Dr. Jeong-Rang Kim’s research team at the Korea Research Institute of Chemical Technology (KRICT), in collaboration with GS Engineering & Construction and Hanwha TotalEnergies, developed catalyst and process technology that directly converts CO₂ and hydrogen into liquid hydrocarbons without intermediate steps. This work was conducted under the Ministry of Science and ICT’s Carbon Resource Platform Chemical Project.

Previously, Dr. Kim’s team completed a 5 kg per day mini-pilot plant and transferred the technology to GS Engineering & Construction and Hanwha TotalEnergies in 2022. Building on this achievement, the joint research team established Korea’s first direct CO₂ hydrogenation pilot plant capable of producing 50 kg of liquid hydrocarbons per day by late 2025. The next phase involves designing a commercial-scale process capable of producing more than 100,000 tons annually.

As geopolitical disruptions such as the recent closure of the Strait of Hormuz threaten petroleum and naphtha supply chains, technologies that transform industrial CO₂ emissions from power plants and factories into valuable resources are gaining strategic importance. This technology offers the potential to replace petroleum feedstocks used for automotive fuels and petrochemical raw materials with carbon-derived alternatives.

Conventional CO₂ conversion technologies typically involve an indirect two-step process. First, CO₂ is converted into carbon monoxide (CO) via the reverse water-gas shift (RWGS) reaction, which requires temperatures exceeding 800°C due to the chemical stability of CO₂. Subsequently, Fischer–Tropsch synthesis converts CO and hydrogen into liquid hydrocarbons under lower temperatures but high pressures, requiring complex multi-stage facilities.

The KRICT-led team overcame these limitations by developing a catalyst system that enables direct conversion in a single process. This direct hydrogenation technology allows CO₂ and hydrogen to react directly into liquid hydrocarbons without the high-temperature RWGS step.

The technology operates under relatively mild conditions of approximately 270–330°C and 10–30 bar. By incorporating multi-stage reactions and recycling unreacted materials, the system currently achieves about 50% synthesis yield for liquid hydrocarbons. The pilot plant’s daily output of 50 kg is roughly equivalent to three 20-liter jerrycans of fuel.

This achievement is particularly significant as a commercialization-enabling platform technology. Improvements in catalyst manufacturing and operating conditions enhanced process stability while reducing energy consumption compared to conventional approaches. The simplified process structure is also advantageous for lowering production costs.

Moving forward, the research team plans to accumulate long-term operational data through pilot plant optimization and demonstration. Based on these results, they will pursue commercial-scale process design, economic feasibility analysis, and greenhouse gas reduction assessments for plants capable of producing over 100,000 tons annually. Successful commercialization could substantially reduce dependence on imported petroleum and strengthen national energy security by establishing alternative carbon feedstock systems.

The researchers anticipate that, when integrated with renewable energy, this technology could become a core enabling component of Power-to-Liquids (PtL) systems, which convert renewable electricity, captured CO₂, and green hydrogen into sustainable liquid fuels.

The study was published as a cover article in the March 2026 issue of ACS Sustainable Chemistry & Engineering (Impact Factor: 7.3), an international journal specializing in sustainable chemical technologies. Dr. Hyung-Ki Min of KRICT served as the corresponding author, and Dr. Chen Jingyu participated as the first author.

New research examines “remorse bias” in legal decision-making




Rutgers University Newark School of Criminal Justice




Two newly published studies by Colleen M. Berryessa, associate professor at the Rutgers University School of Criminal Justice, examine how expressions of remorse are interpreted in the legal system and how those interpretations can contribute to unequal outcomes.

In a recent article published in the Annual Review of Law and Social Science, Berryessa explores the concept of “remorse bias,” showing how judges and other legal decision-makers may misread or misinterpret expressions of remorse due to implicit assumptions, social cognition, and broader societal stereotypes. The review highlights how factors such as criminal history, offense type, mental health, or substance use issues, and racial or cultural background can shape how remorse is perceived and evaluated.

“Assessing remorse is a deeply subjective process shaped by human cognition,” Berryessa explains. “When remorse is misunderstood or discounted, it can produce serious inequities in legal outcomes.”

A second article published in the Journal of Criminal Justice extends this work through an empirical study of judges’ decision-making. Drawing on more than 60 in-depth interviews with state-level trial court judges, Berryessa and coauthor Emily Greberman, a doctoral student at the School of Criminal Justice, develop a model of how remorse bias can emerge during sentencing. Their findings suggest that these cognitive processes may disproportionately influence the sentencing of defendants who are already subject to criminal stereotyping, potentially compounding existing disparities.

Together, the studies underscore the need for greater awareness, education, and training within the legal system to better understand how remorse is assessed and how bias can shape decision-making with far-reaching consequences.

NUTLEY, N.J. – The Hackensack Meridian Center for Discovery and Innovation (CDI) leveraged its continued platform as a nexus for research by hosting its third annual Applied Immunological Research Symposium (AIRS).

The symposium was held at the CDI’s state-of-the-art facility in a bid to bridge the gap between advanced immunological research and its practical application for patient care. The vehicle for this central message was the Center’s focus on innovation and translational science in cellular immunotherapy 

The event brought together a world-class assembly of scientists to share groundbreaking findings aimed at accelerating the next generation of cancer immunotherapies.

According to David Perlin, Ph.D., chief scientific officer and executive vice president of the CDI, “this symposium is a direct reflection of our mission to create a dynamic, collaborative environment translating promising research into clinical practice.”

Flipping the Switch

Keynote speaker and world-renowned immunologist Rafi Ahmed, Ph.D., of Emory University, provided the event’s centerpiece with his keynote address, "What is T Cell Exhaustion?"

In a two-part presentation, Dr. Ahmed first explained the science of T cell exhaustion, where immune cells are "switched off" by inhibitory receptor PD-1—an immune checkpoint protein found on T Cells that acts as that “switch” to turn off immune responses—during chronic disease. 

He then connected this science to patient care, presenting clinical data in oncology patients with the Human Papillomavirus (HPV-positive). His data showed how blocking this PD-1 switch reawakens a core population of "stem-like" T cells, unleashing them to fight disease as the body shifts its natural reaction to an acute infection becoming chronic. 

“Big decisions have to be made early,” marveled Dr. Ahmed during his presentation. He’d continue that our immune systems are “always prepared for chronic, but adjust to acute, infection.”

After an amusing anecdote about collaborating with CDI scientist and colleague Hai-Hui “Howard” Xue, M.D., Ph.D., who provided his own animal models to help with the research process after a quick airport phone call, Dr. Ahmed concluded that these studies have further treatment implications in cancer treatment, a myriad of chronic infections, and various autoimmune diseases.

“Dr. Ahmed’s work has fundamentally reshaped our ability to treat diseases that were once considered intractable,” said Binfeng Lu, Ph.D., director of the CDI’s Institute for Immunologic Intervention (3i) and one of the symposium organizers. “His pioneering work on T cell exhaustion established a foundational conceptual framework for modern immunology and oncoimmunology, and is already saving lives by guiding the development of transformative therapies.”

The Common Threads: Weaving the Science Together

Dr. Ahmed’s address set the stage for a day of robust scientific exchange, featuring presentations from leaders at top research institutions nationwide. 

Key studies and their talking points included:

  • Yi Zhang, M.D., Ph.D., Center for Discovery and Innovation: Dr. Zhang—also one of the symposium organizers—presented novel strategies for the epigenetic reprogramming of T cells. He highlighted the importance of the EZH2 gene in CAR T cell therapy and in tumor control. His work offers a pathway to enhance cancer immunotherapy while simultaneously preventing graft-versus-host disease (GvHD) in transplant patients.

  • Dean Lee, M.D., Ph.D., Nationwide Children's Hospital: Dr. Lee discussed the creation of a universal-donor manufacturing platform for NK and CAR-NK products, especially in pediatric cancers such as leukemia, where treatments such as bone marrow transplant is essential. This breakthrough is a crucial step toward making advanced, off-the-shelf cell therapies more accessible and affordable in multi-site clinical trials.

  • Geoffrey R. Hill, M.D., Fred Hutchinson Cancer Center: Dr. Hill explored complex regulatory networks that govern patient responses to cancer immunotherapy, specializing in the EOMES gene (short for eomesodermin) in commanding T Cell and NK cell cancer response against acute graft-vs.-host disease. While imploring the need for more human studies, he provided key insights into overcoming therapeutic resistance, improving patient outcomes.

  • Olivera J. Finn, Ph.D., University of Pittsburgh School of Medicine: Dr. Finn outlined her pioneering research in developing vaccines for human cancer interception, a triumph in the face of discouraging results over decades of vaccine studies for cancer-therapeutic use. Her work—in itself, an inspiring message of perseverance in the field—presented a shift from treatment to proactive prevention in the fight against cancer.

  • Ming Li, Ph.D., Memorial Sloan Kettering Cancer Center: Dr. Li detailed the fundamental immunological mechanisms of cancer defense. His laboratory’s findings are uncovering new molecular targets to bolster the body’s natural ability to fight tumors. His presentation ended with the suggestion that we “go beyond checkpoint inhibitors” to continue meeting unmet needs in immunotherapy.

The event concluded with one cohesive message: 

The future of cancer treatment lies in collaborative, translational research across public and private sectors.

“We’re passionate about providing a forum for the brightest minds in immunology,” said Dr. Perlin, also a professor of Medical Sciences at the Hackensack Meridian School of Medicine. “By convening such a powerful collection of scientific leaders, the CDI affirms its central role in the global effort to bridge the academic and clinical gap in fighting the world’s most challenging diseases.”
