Robots and AI find a hidden reaction inside 135-year-old chemistry
Chemical reactions are often written as simple equations: starting materials go in, and a product comes out. In reality, the samesubstrates can follow many different pathways depending on their concentrations, temperature, catalysts, and other conditions. Exploring all of these possibilities by hand is practically impossible. Now, advances in laboratory automation and chemical artificial intelligence are allowing researchers to systematically map this vast “reaction hyperspace”—and uncover chemistry that may have remained hidden even in reactions studied for more than a century. To address this question, scientists led by Prof. Bartosz A. GRZYBOWSKI, Director of the Center for Algorithmic and Robotized Synthesis within the Institute for Basic Science (IBS) used an automated robotic platform to explore 960 different sets of conditions for the Biginelli reaction, a classic multicomponent reaction first reported in 1891.

A new strategy enables precise fabrication of nanoporous carbon structures
Nanoporous carbon materials have attracted significant interest for applications in lightweight structural materials, microdevices, and bio-integrated systems due to their low density, chemical stability, electrical conductivity, and tunable mechanical properties. However, existing fabrication approaches often struggle to simultaneously achieve precise patterning, controllable porosity, and desirable mechanical performance. A research team led by Professor Min Qiu at Westlake University has developed a new fabrication strategy, termed Mix-ice lithography (Mix-IL), that enables direct construction of nanoporous carbon structures with tunable pore architectures and complex geometries. The study has been published in Science Bulletin.

Eastlake science students make district history
Three Eastlake High School students made Sweetwater Union High School District history this year when they became the first students from the district to qualify for the International Science and Engineering Fair, an international competition that brings together some of the top high school researchers from around the world. Ronald Wyatt, Giles Del Priore and Ihan Sung advanced to the competition after successful runs at regional and state science fairs. Sung went a step further, placing fourth in the chemistry category at ISEF. The students were recognized on Aug. 10 during a Sweetwater Union High School District board meeting at the district office in Chula Vista.For Wyatt and Del Priore, recent Eastlake graduates, the journey began with a shared concern about dementia and the challenges faced by families caring for loved ones with memory impairment. Their engineering project, “Design and Evaluation of a Behaviorally Grounded Caregiver-Governed AI Companion for Individuals with Memory Impairment,” earned the Sweepstakes Award at the Sweetwater District STEM Fair and first place in its division at the Greater San Diego Science and Engineering Fair. The project explored whether Artificial Intelligence could provide companionship and support while helping reduce stress for people with dementia and their caregivers. “Our inspiration came from personal experience. Both of us have seen family members and loved ones affected by dementia, and we’ve witnessed how overwhelming the caregiving process can be,” Wyatt said. Del Priore said the students also wanted to address the high cost of third-party health care services while creating something that could potentially help their own families as well as people elsewhere. The students developed an AI system designed with safeguards intended to prevent misinformation reinforcement, emotional escalation and unsafe responses. In 240 controlled trials involving memory, identity, agitation and neutral scenarios, they said the system consistently prevented harmful incorrect reinforcement while using context-aware silence, de-escalation and caregiver verification. The project required the students to combine Artificial Intelligence, psychology, neuroscience and human-computer interaction. For Del Priore, one of the biggest technical challenges was getting the AI companion to communicate verbally with a patient. Hardware limitations required the students to collaborate with multiple Python libraries for speech-to-text and text-to-speech functions while keeping the cost of the companion low. “For us, the biggest challenge was translating complex behavioral and cognitive care principles into a functioning AI system,” Wyatt said.Qualifying for ISEF was a milestone that student expected. The international competition proved to be another milestone. “Competing at ISEF was an incredible experience and unlike anything we’ve ever done before,” Del Priore said. “Being surrounded by some of the most talented young researchers from around the world was both inspiring and motivating.” He said the experience stood out because of the emphasis on collaboration, innovation and scientific discovery. “The most memorable part was seeing how people from completely different backgrounds and disciplines approached solving real-world problems with creativity and passion,” he said. The students also credited teachers and mentors who supported their work. Del Priore said his sophomore-year AP Physics teacher, Dr. Price, was particularly influential. “Through all of my personal and academic struggles, Dr. Price always believed in me,” Del Priore said. “All of his faith in me really molded me into the person I am today and helped create my love for science even through tough times.” Wyatt is continuing his education at UC Santa Cruz, where he plans to study biomolecular engineering and bioinformatics, with an interest in research involving Artificial Intelligence, biology and health care. Del Priore plans to double major in chemistry and accounting. Sung, a rising Eastlake senior, qualified for ISEF after winning first place in the Engineering: Energy, Materials & Transport category at the Greater San Diego Science and Engineering Fair and first place in chemistry at the California Science and Engineering Fair. His project, “Renewable Ammonia Electrochemical Synthesis by Glow Discharge with an Iron-Based Catalyst,” involved a device he designed and engineered to produce renewable ammonia, with potential applications in fertilizer production and energy storage. Sung became interested in the project after considering the relationship between food insecurity and fertilizer costs. His system uses plasma to break apart nitrogen molecules so they can interact with hydrogen and form ammonia. At ISEF, Sung competed against more than 1,700 students from 65 countries and earned fourth place in chemistry. “I am proud to become one of te first students in the district to qualify for ISEF because this milestone can inspire others in the district to attain similar goals,” Sung said.

Reimagining how scientists study the chemistry of the air
Professor Victoria Barber and doctoral student Cooper Crabtree are spearheading Keck Foundation-funded project charting a path toward better understanding atmospheric oxidation. by Álvaro Castillo, UCLA College of Letters and Science From the vantage point of Victoria Barber, a UCLA assistant professor of chemistry and biochemistry, understanding the chemical reactions that shape air quality and climate are among the most pressing scientific challenges of our time. And thanks to a recent grant from the W.M. Keck Foundation, she and doctoral student Cooper Crabtree will spearhead a new research project exploring exactly how pollutants form in the atmosphere. Specifically, the project will examine how volatile organic compounds transform through atmospheric oxidation and explore how pollutants, like smog, form in the atmosphere. VOCs are released by sources ranging from trees and wildfires to vehicle exhaust pipes and consumer products such as cologne and perfume. As they undergo atmospheric oxidation, they can transform into a wide range of other compounds. Anyone in Southern California can attest to the urgency of this area of research — for example, in late July of this year, Los Angeles County was under an active ozone pollution advisory for almost a full week. While many people associate ozone with the protective ozone layer high in the stratosphere, ground-level or tropospheric ozone is a harmful secondary pollutant formed through atmospheric oxidation. Understanding how VOCs transform into pollutants like ozone is therefore critical to improving air-quality forecasts and informing strategies to reduce exposure. “My group is focused on trying accelerate our understanding of these networks of reactions so that we can do a better job of predicting how those pollutants form,” Barber said. “When we make decisions about how we might alter emissions, we can understand how that’s going to influence the production of these downstream pollutants.” With support from the W. M. Keck Foundation, Barber and Crabtree are developing new experimental approaches that will combine — and improve — techniques to study hundreds of chemical systems more efficiently than traditional methods allow. Instead of spending years decoding a single VOC, the project seeks to dramatically expand the pace and scale of discovery. The grant comes at a particularly important moment for environmental research. Barber, who joined UCLA in 2023, says funding for climate and air-quality research, especially for early career scientists, has become increasingly difficult to secure, a challenge compounded for ambitious projects that require building entirely new research infrastructure. The Keck Foundation’s support, Barber said, provides the flexibility to pursue bold early-stage, high-risk ideas that may be more difficult to fund using conventional federal funding sources. “It’s really, really hard to do environmental research under the current federal paradigm,” Barber said. “By stepping in and providing stable and flexible funding to explore this new idea, the Keck Foundation is making a huge difference to my research program.” In addition to funding early-career faculty, the Keck Foundation’s support is also focused on empowering graduate students like Crabtree in their scientific growth. The project gives Crabtree the opportunity to help develop an entirely new experimental approach to studying atmospheric chemistry — an experience that will provide him with valuable technical skills, scientific training and preparation for the next stage of his career. Stable funding also allows doctoral students like Crabtree to devote themselves more fully to research rather than balancing their scientific work with additional teaching responsibilities needed to cover funding gaps. “Getting to devote more of my time to research this past school year has greatly improved the pace and quality of our experiments, data analysis and planning for our future work,” said Crabtree, who is pursuing a Ph.D. in chemistry. “I feel very lucky — especially amid the current uncertainty surrounding scientific funding — to be able to continue exploring exciting knowledge gaps in our field and growing as a scientific researcher.” For Barber, mentorship is among the most rewarding and important aspects of her role as a faculty member. “Our jobs as faculty are to do good science and make good scientists,” she said. “I believe the Keck Foundation shares this belief and sees the potential positive impact this project can have.”

Business Restructuring Review Vol. 25 No. 4 July-August 2026
In This Issue New York Bankruptcy Court: Premature Allegations of Creditor Mistreatment Insufficient to Deny Chapter 15 Recognition of Foreign Restructuring Proceeding In In re ARD Finance, S.A., No. 25-12794 (MG), 2026 WL 817458 (Bankr. S.D.N.Y. Mar. 25, 2026), the U.S. Bankruptcy Court for the Southern District of New York was presented with a petition seeking chapter 15 recognition of Luxembourg's recently enacted bankruptcy law governing judicial reorganization proceedings. The court granted the petition, turning aside challenges to recognition voiced by a creditor group arguing that recognition should be denied based upon allegations of unfairness to creditors in the Luxembourg proceeding that would make recognition manifestly contrary to U.S. public policy. According to the bankruptcy court, recognition was warranted because: (i) the rules and procedures governing the proceeding under Luxembourg law were fundamentally fair; (ii) the petition otherwise satisfied chapter 15's recognition requirements; and (iii) the creditor group's allegations were premature, given the fact that the Luxembourg court presiding over the debtor's restructuring proceeding had not confirmed a restructuring plan, and all creditors had the right to participate fully and voice their objections in the proceeding (including the right to appeal an order approving a plan).

Apr. 6, 2026), the U.S. Bankruptcy Court for the Southern District of Florida granted in part and denied in part post-recognition motions filed by an insider of a foreign debtor seeking to bar or limit discovery sought by the debtor's foreign representative concerning allegedly voidable transfers involving the debtors' U.S. real property. According to the court: (i) although chapter 15 includes its own discovery provisions among the relief that may be granted to a foreign representative, the expansive discovery available in cases under other chapters of the Bankruptcy Code is also available in chapter 15 cases; (ii) the discovery sought by the foreign representative was permissible; (iii) discovery regarding matters that were the subject of a pending adversary proceeding had to be undertaken under the more restrictive rules applicable to such proceedings; and (iv) a discovery request would be barred to the extent that it sought production of documents or testimony from a subpoenaed entity that exceeded the geographic limitations specified in such rules.

(In re Credito Real S.A.B. de C.V. SOFOM, E.N.R.), 677 B.R. 192 (D. Del. 2026), appeal filed, No. 26-2356 (3d Cir. June 5, 2026), the U.S. District Court for the District of Delaware affirmed a bankruptcy court order granting chapter 15 recognition to a Mexican "concurso mercantile" proceeding and enforcing nonconsensual third-party releases approved by the Mexican court. Agreeing with the bankruptcy court that the releases were not manifestly contrary to U.S. public policy, the district court concluded: "It is well settled that U.S. bankruptcy courts can give effect to foreign orders in recognized foreign proceedings pursuant to the authority granted in Chapter 15, even when those orders contain relief unavailable under U.S. law. [The appellant's] arguments misconstrue the Supreme Court's narrow holding in Purdue, applicable in Chapter 11 cases, as well as the statutory framework of Chapter 15 and its core policy objectives. Accordingly, I will affirm the Enforcement Order." The ruling has been appealed to the U.S. Court of Appeals for the Third Circuit.

EP Energy E&P Co., LP (Matter of EP Energy E&P Co., LP), 169 F.4th 609 (5th Cir. 2026), the U.S. Court of Appeals for the Fifth Circuit affirmed lower courts' rulings disallowing a creditor's administrative expense claim. It also rejected the creditor's argument that, because the claims were predicated on state law, a state court should adjudicate the merits of the state law causes of action before the bankruptcy court could allow or disallow the claim as an administrative expense. According to the Fifth Circuit, even though the causes of action were based on state law, the bankruptcy court had jurisdiction to determine whether the creditor's claims should be conferred with administrative expense priority in the debtors' chapter 11 case. [read more …] New York Bankruptcy Court: Dismissal of Involuntary Chapter 11 Case Filed Prior to Commencement of Foreign Restructuring Proceeding Unwarranted In In re Xinyuan Real Estate Co. Ltd., No. 25-10745 (PB), 2026 WL 592250 (Bankr. S.D.N.Y. Mar. 3. 2026), the U.S. Bankruptcy Court for the Southern District of New York considered the bona fides of an involuntary chapter 11 petition filed by certain holders of U.S. dollar-denominated notes against a holding company for a group of Chinese property development companies that filed a restructuring proceeding in the Cayman Islands after the noteholders filed the involuntary chapter 11 petition. The court denied the debtor's motion to dismiss the chapter 11 case. Given the timing of the filing of the Cayman Islands restructuring proceeding, the absence of any progress in the proceeding for seven months, the debtor's need to restructure notes governed by U.S. law, and the debtor's lack of any meaningful contacts to the Cayman Islands, dismissal of the chapter 11 case was unwarranted under the applicable provision of the Bankruptcy Code, international comity, or the doctrine of forum non conveniens. [read more …] Bankruptcy Court Evaluates Trustee's Authority to Sell Avoidance Actions and Right of Target Defendants to Object In In re Law Enf't Officers Sec. Union, No. 24-70277-JAD, 2026 WL 560452 (Bankr. W.D. Pa. Feb. 27, 2026), a chapter 7 trustee sought court approval to sell certain avoidance actions to a creditor of the debtor's estate. Potential targets of the subject avoidance actions objected, arguing that such claims were nontransferable powers of the trustee rather than saleable estate property and urging the court to approve their competing settlement with the trustee. The U.S. Bankruptcy Court for the Western District of Pennsylvania disagreed with the potential defendants, holding that they lacked standing to object to the proposed sale, that avoidance actions are indeed estate property, and that the sale—rather than the settlement—best served the estate's interests.

Buddy Ayers Construction Inc., No. 25-6, 2026 WL 1686028 (U.S. June 11, 2026), the U.S. Supreme Court overturned a Fifth Circuit decision judicially estopping a chapter 13 debtor from asserting a personal injury claim against a construction company because the debtor failed to disclose the claim during his bankruptcy case. In so ruling, the Court held that "[t]he Fifth Circuit erred by artificially narrowing its inquiry to whether the debtor had knowledge of the underlying facts or a potential motive to conceal the claim." It represents the first time that the Court has applied judicial estoppel in the bankruptcy context, although it has suggested in other contexts that it may be inappropriate where an inconsistent legal position resulted from "inadvertence or mistake." Also in June, the Court denied petitions for certiorari in a few notable bankruptcy cases.

The article discussed U.S. Bankruptcy Judge Christopher Lopez's July 7, 2026, ruling that participating lenders in Serta Simmons Bedding's 2020 non-pro rata uptier exchange breached the credit agreement's ratable-sharing provision, and awarding excluded lenders more than $261 million in damages. The opinion resolves six years of litigation related to Serta's 2020 transaction, where it raised $200 million in new financing and exchanged $1.2 billion of term loans for $875 million in superpriority debt. Judge Lopez found that the debt-for-debt exchange constituted a "payment" under the credit agreement, requiring proportional sharing among lenders, and dismissed various defenses raised by the participating lenders.

Does public health *need* MAHA?
Last week, our friend Dr. Craig Spencer sparked an ongoing volatile discussion with his Atlantic article “Public Health Needs MAHA.” Some have come out in strong dissent, others are cheering, and others are simply lamenting that we find ourselves in such a divided world to begin with. We will dare to dip our toes in these controversial waters, too. Does public health need MAHA? We think in some ways yes, and in other ways, no. MAHA leaders versus the everyday MAHA supporter The vitriol in this debate mostly comes from one collapsed distinction: the leadership of MAHA is not necessarily the same as the people who support it. Say “MAHA” and most people picture RFK Jr. Fair enough, as he coined the term and holds most of the power. And, yes, some MAHA followers treat Kennedy as something close to a saint. But talk to the grassroots, and it’s not a monolith. They’re Republicans, Democrats, and Independents. People who distrust vaccines and vaccine supporters. It’s a wide, eclectic coalition. The data backs this too: 4 in 10 Americans support the movement—that’s a lot of people! But according to polls, vaccines and medical choice (the issues most tied to Kennedy personally) are cited by only 4% as their reason for supporting the movement. For many, the motivations are much broader. Many MAHA supporters are signing up for the idea that “something needs to change” with health in this country. They’re asking good-faith questions about corporate influence on our health systems, health care costs, nutrition, chemicals, and clean air and water. These are all questions that plenty of public health professionals recognize as legitimate and also care about very deeply. Blurring the lines between the leadership and grassroots does real damage in two important ways: It hands the 4 in 10 exactly the narrative already fed—that the health ecosystem doesn’t listen, doesn’t care, and paints every critic with the same brush. It gives the actual bad actor more power. RFK Jr. has done irreparable damage and can’t be trusted. What the MAHA movement gets right A healthy population is something the public health field was literally built on, and many of these topics are things we have dedicated our lives to. Yet the MAHA movement has captivated nearly half the country in a way the public health establishment has failed to achieve. So that means MAHA is doing something right. Some of it may be timing (after a Covid-19 pandemic and deep frustration and mistrust with institutions). The movement also does three other things really well: 1. It gives a new, louder voice to system failures. While MAHA is not a monolith, one theme stays consistent across their stories: the system failed them. For some, it was the system that flooded their communities with opioids and then walked away. For others, it was the system that let their business collapse during Covid with no safety net in sight. For others still, it was the system that failed to help them manage a complex chronic illness, bouncing them from physician to physician without any real answers. And in many ways, our health ecosystems are failing Americans. Why are medical bills so incomprehensible? Why do some kids get a healthy school lunch and others don’t? Why do an epidemiologist and a MD/PhD student have to start newsletters in the middle of the biggest public health emergency in a century, just so people can get straight information? Because the systems failed. This deep-seated frustration driving many Americans to search for solutions elsewhere needs to be recognized. 2. MAHA has brilliant comms central to their efforts. MAHA figured out something most health institutions still have not: the information landscape changed. It’s participatory now, not top-down; influence runs through many nodes in a community, not one institution; and storytelling and telling audiences “what you really think” moves people more than data dumps do. MAHA goes where audiences are listening, using podcasts, social media, and memes in ways most health institutions would scoff at—but it works. 3. They are very good at organizing. A MAHA meeting feels like a rally: energy, speakers, music, and most importantly, an action for everyone. Someone’s writing the next policy brief, someone’s seeding a narrative, someone knows the next legislative deadline, someone’s sending the text messages for a campaign. None of this is new (ask the civil rights movement), but MAHA knows it works and has capitalized on it. What MAHA gets wrong This list could be much longer, and this newsletter has spent a lot of time covering it, but here are a few things: Poor use of scientific evidence. This is the fundamental problem with many MAHA policies: the hype outpaces the science, and experts are often villainized for pointing this out. MAHA leadership has traded real solutions for cheap wins. For example, instead of taking on the powerful food industry and passing real reforms, it has celebrated french fries made of beef tallow and taken out artificial dyes from still very sugary children’s cereal. These changes won’t move the needle on America’s diet. MAHA leadership has tried to dismantle vaccine access in the U.S. While many MAHA supporters emphasize other issues, the effort to change vaccine policy has become MAHA’s signature effort. This is not surprising given RFK Jr.’s extensive track record campaigning against vaccines. It has rallied behind the wrong leader. RFK Jr. has a decades-long track record of villifying doctors, scientists, and public health workers, well before he became HHS secretary. He is known for his decades-long work sowing distrust in vaccines as well as life-saving treatments like antiretroviral therapy for HIV. This is not a serious person who can move the needle on health in the U.S, and he has already done serious damage. Public health needs more than defense Defending the evidence is absolutely necessary so health in the U.S. doesn’t move further backward. The public health establishment is very good at defense. The problem is this defense often sounds like defending the status quo, which has failed many people. Public health needs to offer an alternative to RFK Jr.’s MAHA—one that is rooted in evidence, truly listens to and addresses people’s frustrations, and has innovative solutions and the courage to change the systems. How do we get there? Find common ground. Do you know what most people care most about? The abysmal cost of healthcare. Start there. Fight for the human loudly. Too often, communications and engagement center on science with a capital S, funding mechanisms, or the CDC/FDA/NIH. Not the person. So the public doesn’t see themselves in it. Instead, they see people fighting for the very powerful systems that they feel negatively impact their health and well-being. Let the public feel and hear that you see their frustrations, you get it, and you’re fighting for them within the system. Recognize when pro-science messages are alienating people. Facts absolutely matter, but angrily venting only alienates people further. Our friend Elisabeth Marnik recently wrote a New York Times article about her experience growing up unvaccinated and how listening and empathetic conversation are the only ways to reach people that really work (a position backed by communication science). Her comments section was full of hateful comments from pro-vaccine individuals attacking her for daring to suggest we approach vaccine-hesitant individuals with empathy. It is possible to both stand firm behind scientific evidence and empathize with people who don’t trust it. Lean into politics smartly. Often, public health has shied away from politics: Don’t touch it, lest you get burned. But this fails to recognize that the third rail is what fuels the train: who is elected determines our budgets, our priorities, and our authority. Being political means being very savvy in strategy on both sides of the aisle, knowing your audience, and recognizing that political capital is as scarce as financial resources and needs to be allocated accordingly. Bottom line So does public health need MAHA? That’s not really the right question. Public health has a responsibility not to dismiss 40% of the country who feel heard by this movement and are frustrated that the system has failed them. And it has a responsibility to stick to the evidence and recognize MAHA leadership for what it is: a danger to our nation’s health. Both can, and should, be done.

When It Comes to Fusion, Materials Matter
Fusion at high temperatures powers the sun and, if harnessed, could provide a potential source of energy here on Earth. But controlling fusion reactions has other benefits. The process also generates subatomic particles called neutrons that are used in a range of applications spanning medicine, research, and national security. Now, scientists at the University of California, Davis (UC Davis), and the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have found that the materials surrounding a fusion reaction can dramatically increase how often it occurs, particularly at low energies where fusion is rare. The study was published July 18 in Nature Communications. Their approach sets up a way to study and engineer nuclear reactions within solid materials, opening a new field of “materials-driven fusion.” Instead of designing materials just to survive the harsh conditions of fusion, researchers might be able to design materials that boost the reaction in specific conditions, similar to the way catalysts speed up chemical processes. “It gives you a new knob to turn that you didn’t have before,” said Arun Persaud, head of the Fusion Science & Ion Beam Technology group in Berkeley Lab’s Accelerator Technology & Applied Physics (ATAP) Division. “If we understand this effect better, it opens the door to engineering new materials that would affect the fusion rate under certain conditions. Someday future progress might enable more compact and efficient neutron generators, which have all kinds of applications, like cargo screening, planetary science, and medical therapy and imaging.” In the experiment, researchers used two different methods to pack deuterium, a heavy form of hydrogen atoms that is often used in fusion, into thin foils of palladium and titanium. They then fired a beam of deuterium ions at the foils at different energies and measured how often fusion happened. Then they compared the rates from the different materials and methods with the “bare” fusion reaction (not in a material). The team found that fusion rates depended on how the deuterium was loaded into the metal foils. The biggest effect was at the lowest energies, below 2.5 kiloelectronvolts (keV), where theory predicts fusion rates drop off sharply. Instead, researchers found a surprising plateau: Some samples showed elevated fusion rates roughly a quintillion times higher than bare fusion reactions. (A quintillion is a 1 followed by 18 zeroes.) Researchers are not exactly sure why that’s happening, though they have some ideas and ways to test them. The electrons and defects within the material might partially shield repulsive electrostatic forces between deuterium nuclei, making it easier for them to get close together and fuse. Tuning the electronic structure, defects, and composition of materials could help make nuclear reactions happen more readily. “It comes down to better understanding the mechanism so that we can try to enhance it,” said corresponding author Jeremy Munday, a professor at UC Davis. “We’ve seen that we can increase fusion rates, but what is the limit? Can we bring it to lower temperatures or energies? There’s obviously a lot of interest and excitement about fusion, so if there’s something we can learn about the physics at these lower energy scales, maybe there’s something we can translate to other areas of nuclear science.” The team plans to explore a wider range of materials and continue probing the unexpected fusion plateau at lower energies. Their work establishes a reproducible experimental platform to study how solid materials influence nuclear reactions, creating a new area of research that links fusion science with materials science and chemistry. “The work shows conclusively that the material environment where fusion occurs at low temperatures is an active participant rather than a passive container,” said Cameron Geddes, director of ATAP. “That adds a new dimension to fusion research.” This work was funded by the U.S. Department of Energy’s Advanced Research Projects Agency-Energy (ARPA-E). ### Lawrence Berkeley National Laboratory (Berkeley Lab) is committed to groundbreaking research focused on discovery science and solutions for abundant and reliable energy supplies. The lab’s expertise spans materials, chemistry, physics, biology, earth and environmental science, mathematics, and computing.
