Space suit experiment lands on the moon
University of Delaware research made a moon landing on Sunday along with other experiments aboard the unmanned Blue Ghost spacecraft. These projects will help scientists better understand what it will take to successfully land humans on the moon, and could possibly pave the way for an extended stay. The experiment led by UD researcher Norman Wagner and his company STF Technologies, LLC, aims to determine how moon dust particles stick to different materials exposed to the moon’s environment. These particles, called regolith, are fine and very sharp, similar to volcanic rock or dust found on Earth. Prototype spacesuit materials made by UD and STF Technologies will be tested for their ability to repel this moon dust in experiments strapped outside a lunar lander designed to carry payloads to the moon’s surface. The UD spacesuit shell textiles are treated with multiple nanotechnologies, including shear thickening fluid, a revolutionary material co-developed by UD and STF Technologies that normally behaves like a liquid, but becomes a solid under impact, a useful feature when puncture resistance is a priority. The hope is that beyond puncture protection, the STF-infused spacesuit textiles will offer greater dust deterrence, increasing the material’s lifespan in space. Other RAC experiments will test materials for solar cells, optical systems, coatings and sensors. In other related work, the Wagner lab currently has experiments aboard the International Space Station (ISS) through a NASA collaboration to develop new construction materials for lunar exploration. These ISS experiments, part of a Materials International Space Station Experiment (MISSE) that launched last November, extend Wagner’s previous work on ways to make concrete in space, for such items as rocket landing pads, buildings, roads, habitats and other structures. More recent work in the Wagner lab by undergraduate researchers and doctoral students focuses on methods for curing 3D-printed materials in space, including using microwave technology. “Here we aren’t trying to get rid of the moon dust — we are trying to leverage it to create extraterrestrial cement through additive manufacturing on the moon,” said Wagner, Unidel Robert L. Pigford Chair in the Department of Chemical and Biomolecular Engineering. Contact mediarelations@udel.edu to set up an interview.
UPI news service interviewed Dr. Meena Bose for the article “Trump USAID cuts create vacuums of food, medical care for vulnerable populations.” The president’s effort to downsize government agencies makes good on one of his biggest campaign promises, according to Dr. Bose. While presidents have attempted to increase the efficacy of agencies in the past, the article says Trump’s approach is different. “This is kind of a hatchet approach to doing so but I think it has a certain appeal to the president’s constituencies,” Bose told UPI. “He’s getting things done, cutting through red tape.” Dr. Bose is a Hofstra University professor of political science, executive dean of the Public Policy and Public Service program, and director of the Kalikow Center for the Study of the American Presidency.
The Power of Refusal: Socially Conscious Boycotts and Corporate Accountability
In today's world, information travels faster than you can say "Google it!" This hyper-connectivity means companies are more exposed than ever when it comes to taking stances or actions on social issues, And a boycott can be a force to reckon with. With social media as their megaphone, these retail boycott campaigns can quickly capture global attention, asking consumers not to spend money in stores or online for a day or even an extended period of time. It's an increasingly common dilemma for corporations and their bottom line. Says David Primo, professor of political science and business administration at the University of Rochester: “Companies need to figure out what they will take positions on, what they won’t take positions on, and then stand firm. Holding your finger to the political winds is not an effective way to run a company in a polarized world.” ```
Villanova Professor Sees Costs and Benefits in Corporate and Federal Return-to-Office Mandates
In early February, federal agencies submitted plans in accordance with an executive order to initiate an estimated 1 million government employees’ full-time return to their duty stations. The departments’ actions are among the latest in a series of RTO moves enacted since the start of 2025. Notably, they follow policy changes by corporate giants Amazon, AT&T and JPMorgan, who in January began requiring five days of in-person work for select staffers, with justifications ranging from strengthening culture to improving performance. With more employers expected to require in-office work in the coming months, some predict that 2025 could be the “year of the RTO mandate.” But, given the arguments from those pushing for these policies, it’s worth asking: Are these return-to-office requirements truly justified? Do they actually improve communication, strengthen teams and boost productivity, as supporters claim? According to Kyoung Yong Kim, PhD, whose research focuses on telework, strategic human capital management and employee-organization relationships, the answer is complicated—and highly circumstantial. Dr. Kim says that, by gathering coworkers around the proverbial water cooler, RTO policies can in some cases facilitate dialogue, promote teambuilding and foster organizational success. Yet, in other instances, work-from-home (WFH) arrangements can significantly boost employee morale, efficiency and output. “In a recent paper, my colleague Ijeoma Ugwuanyi [a professor at Hong Kong Metropolitan University] and I examined how social distancing initiatives, which reduce interactions among people, impact working relationships,” says Dr. Kim. “We found that they can actually help improve negative ones, at least in employees’ minds.” Analyzing data collected on 105 working relationships among 43 full-time personnel at a South Korean healthcare company, Dr. Kim and Dr. Ugwuanyi discovered that, when afforded extended WFH privileges, colleagues previously at odds were given the space necessary to reassess their outlooks and improve their dynamics—especially when the individuals involved were viewed as competent and warm. As a result, these repaired relationships generally empowered more effective collaboration in the long run. Additionally, employees with positive in-person relationships maintained a solid rapport even when geographically apart. “These findings are particularly relevant as corporate and government workers increasingly return to their offices,” says Dr. Kim. “Managers need to remember that, according to the research, employees are willing to reset negative relationships they had previously. That said, returning to the office also offers a chance to strengthen relationships and make them more positive, which is crucial since team dynamics are a key determinant of team performance.” Per Dr. Kim, in order to best position themselves for success on the RTO front, organizations need to take a measured, sympathetic approach in facilitating their in-office policies, with an eye toward mitigating negativity. They need to remain cognizant of the logistical and interpersonal challenges that could emerge in the wake of a return, address their employees’ concerns in an attentive manner and foster a “supportive climate characterized by supportive behaviors.” It’s a situation that Dr. Kim says bears parallels—perhaps somewhat counterintuitively—to the mass shift to telework that occurred during the COVID-19 pandemic. As he found in his research on that phenomenon, employees responded best to changes in their working arrangements when organizational leaders and managers took the time to explain and actively discuss the reasoning behind them, especially in mission-driven terms. “Essentially, an important implication of the findings is that, to sustain employees’ positive attitudes and behaviors, it is crucial to frame these moves in a way that highlights how working in the office benefits both employees and the organization,” says Dr. Kim. In turn, RTO-focused organizations should recognize that their words and messages have a very real impact, particularly when scrutinized by workers who may not be happy about resuming their morning commutes. “Amazon, for instance, appears to be taking a thoughtful approach by emphasizing the value of collaboration with colleagues and the enrichment of organizational culture,” says Dr. Kim. “One potential drawback, however, lies in their message about the consequences of non-compliance, specifically that failure to adhere to the in-office policy could jeopardize employees’ chances of promotion. “A more positive framing, emphasizing how such policies support professional growth as well as employees’ well-being, could enhance favorable perceptions and work behaviors.” In the event organizations remain attuned to such situations—taking their employees’ perspectives into account, actively communicating their intentions and presenting clear value propositions—Dr. Kim thinks a year of the RTO mandate could potentially be a less daunting prospect. And maybe, with time, the transition back from Zoom to the boardroom could be a beneficial one.
3D-printed lung model helps researchers study aerosol deposition in the lungs
Treating respiratory diseases is challenging. Inhalable medicines depend on delivering particles to the right lung areas, which is complicated by factors like the drug, delivery method and patient variability, or even exposure to smoke or asbestos particles. University of Delaware researchers have developed an adaptable 3D lung model to address this issue by replicating realistic breathing maneuvers and offering personalized evaluation of aerosol therapeutics. “If it's something environmental and toxic that we're worried about, knowing how far and how deep in the lung it goes is important,” said Catherine Fromen, University of Delaware Centennial Associate Professor for Excellence in Research and Education in the Department of Chemical and Biomolecular Engineering. “If it's designing a better pharmaceutical drug for asthma or a respiratory disease, knowing exactly where the inhaled aerosol lands and how deep the medicine can penetrate will predict how well that works.”that can replicate realistic breathing maneuvers and offer personalized evaluation of aerosol therapeutics under various breathing conditions. Fromen and two UD alumni have submitted a patent application on the 3D lung model invention through UD’s Office of Economic Innovation and Partnerships (OEIP), the unit responsible for managing intellectual property at UD. In a paper published in the journal Device, Fromen and her team demonstrate how their new 3D lung model can advance understanding of how inhalable medications behave in the upper airways and deeper areas of the lung. This can provide a broader picture on how to predict the effectiveness of inhalable medications in models and computer simulations for different people or age groups. The researchers detail in the paper how they built the 3D structure and what they’ve learned so far. Valuable research tool The purpose of the lung is gas exchange. In practice, the lung is often approximated as the size of a tennis court that is exchanging oxygen and carbon dioxide with the bloodstream in our bodies. This is a huge surface area, and that function is critical — if your lungs go down, you're in trouble. Fromen described this branching lung architecture like a tree that starts with a trunk and branches out into smaller and smaller limbs, ranging in size from a few centimeters in the trachea to about 100 microns (roughly the combined width of two hairs on your head) in the lung’s farthest regions. These branches create a complex network that filters aerosols as they travel through the lung. Just as tree branches end in leaves, the lung’s branches culminate in delicate, leaf-like structures called alveoli, where gases are exchanged. “Those alveoli in the deeper airways make the surface area that provides this necessary gas exchange, so you don't want environmental things getting in there where they can damage these sensitive, finer structures,” said Fromen, who has a joint appointment in biomedical engineering. Mimicking the complex structure and function of the lung in a lab setting is inherently challenging. The UD-developed 3D lung model is unique in several ways. First, the model breathes in the same cyclic motion as an actual lung. That’s key, Fromen said. The model also contains lattice structures to represent the entire volume and surface area of a lung. These lattices, made possible through 3D printing, are a critical innovation, enabling precise design to mimic the lung's filtering processes without needing to recreate its full biological complexity. “There's nothing currently out there that has both of these features,” she explained. “This means that we can look at the entire dosage of an inhaled medicine. We can look at exposure over time, and we can capture what happens when you inhale the medication and where the medicine deposits, as well as what gets exhaled as you breathe.” The testing process Testing how far an aerosol or environmental particle travels inside the 3D lung model is a multi-step process. The exposure of the model to the aerosol only takes about five minutes, but the analysis is time-consuming. The researchers add fluorescent molecules to the solution being tested to track where the particles deposit inside the model’s 150 different parts. “We wash each part and rinse away everything that deposits. The fluorescence is just a molecule in the solution. When it deposits, we know the concentration of that, so, when we rinse it out, we can measure how much fluorescence was recovered,” Fromen said. This data allows them to create a heat map of where the aerosols deposit throughout the lung model’s airways, which then can be validated against benchmarked clinical data for where such aerosols would be expected to go in a human under similar conditions. The team’s current model matches a healthy person under sitting/breathing conditions for a single aerosol size, but Fromen’s team is working to ensure the model is versatile across a much broader range of conditions. “An asthma attack, exercise, cystic fibrosis, chronic obstructive pulmonary disorder (COPD) — all those things are going to really affect where aerosols deposit. We want to make sure our model can capture those differences,” Fromen said. The ability to examine disease features like airway narrowing or mucus buildup could lead to more personalized care, such as tailored medication doses or redesigned inhalers. Currently, inhaled medicines follow a one-size-fits-all approach, but the UD-developed model offers a tool to address these issues and understand why many inhaled medicines fail clinical trials.

Slow traffic, fast food: The effects of highway congestion on fast-food consumption
Sitting in your car at 5:15 p.m. on a Tuesday, vehicles line the highway as far as the eye can see. The GPS estimates you still have 30 minutes left in traffic, and a vision of your empty fridge passes through your mind as your stomach grumbles. You are faced with a decision: stop at the grocery store to buy ingredients to make dinner or follow one of the many fast-food beacons illuminated beyond the exit sign. According to new research from Panka Bencsik, Assistant Professor of Medicine, Health, and Society, Vanderbilt University, on days when highways are more congested, particularly during weekday afternoon rush hour, people are more likely to choose the fast-food option. Bencsik worked in collaboration with researchers at the University of Pittsburgh and the University of Illinois Urbana-Champaign to analyze the causal effect of time lost on food choice in Los Angeles County. The team analyzed smartphone GPS data from 2017 to 2019 to track foot traffic to restaurants and grocery stores during periods of heavy traffic congestion. “These results are concerning from a public health standpoint,” Bencsik said. “Fast food tends to be higher in fat, sodium, and energy density, and lower in whole grains, fruits, vegetables, and nutrients than food consumed at home. The time commuters spend in congested traffic has substantial implications for eating habits and potentially caloric intake.” Prior research estimates that people consume about 134 more calories per meal when they eat elsewhere versus eating at home. Bencsik said looking at that combined with the results of this study, which also suggests a decrease in visiting supermarkets, likely leads to unhealthier eating habits as a result of traffic congestion. Bencsik said the results of the study also do not suggest that people are swapping their planned “take out day” for the day with more traffic, but they are instead choosing to visit fast-food restaurants more in total. “Increased consumption of fast food due to traffic congestion during peak travel times potentially plays a role in the rise in obesity, heart failure, and diabetes among Americans, given that fast food is typically less healthy than other options,” Bencsik said. “Our results suggest that policies aimed at reducing time spent commuting by car could help battle unhealthy eating habits. For example, improving infrastructure to mitigate traffic congestion, or expanding and speeding up public transport, could reduce fast-food dependency. Increasing work-from-home opportunities and reducing the number of days workers go into work could also have a meaningful impact.” The full paper, "Slow traffic, fast food: The effects of time lost on food store choice," is published in the Journal of Urban Economics.
Aston University collaboration to develop injectable paste which could treat bone cancer
A £110k grant from Orthopaedic Research UK is to help to conduct the work Study is a collaboration with The Royal Orthopaedic Hospital Researchers to use gallium-doped bioglass to produce a substance with anticancer and bone regenerative properties. Professor Richard Martin Aston University is collaborating in research to develop an injectable paste which could treat bone cancer. The Royal Orthopaedic Hospital has secured a £110,000 grant from Orthopaedic Research UK to conduct the work. The project will see researchers at the hospital and the University use gallium-doped bioglass to produce a substance with anticancer and bone regenerative properties. If proved effective it could be used to treat patients with primary and metastatic cancer. Gallium is a metallic element that when combined with bioactive glass can kill cancerous cells that remain when a tumour is removed. It also accelerates the regeneration of the bone and prevents bacterial contamination. A recent study led by Aston University found that bioactive glasses doped with the metal have a 99 percent success rate of eliminating cancerous cells. Dr Lucas Souza, research lab manager at the hospital’s Dubrowsky Lab is leading the project. He said : “Advances in treatment of bone cancer have reached a plateau over the past 40 years, in part due to a lack of research studies into treatments and the complexity and challenges that come with treating bone tumours. Innovative and effective therapeutic approaches are needed, and this grant provides vital funds for us to continue our research into the use of gallium-doped bioglass in the treatment of bone cancer.” Professor Richard Martin who is based in Aston University’s College of Engineering and Physical Sciences added: “The injectable paste will function as a drug delivery system for localised delivery of anticancer gallium ions and bisphosphonates whilst regenerating bone. Our hypothesis is that this will promote rapid bone formation and will prevent cancer recurrence by killing residual cancer cells and regulating local osteoclastic activity.” It is hoped the new approach will be particularly useful in reducing cancer recurrence and implant site infections. It is also thought that it will reduce implant failure rates in cases of bone tumours where large resections for complete tumour removal is either not possible, or not recommended. This could include incidents when growths are located too close to vital organs or when major surgery will inflict more harm than benefit. It could also be used in combination with minimally invasive treatments such as cryoablation or radiofrequency ablation to manage metastatic bone lesions. Dr Souza added: “The proposed biomaterial has the potential to drastically improve treatment outcomes of bone tumour patients by reducing cancer recurrence, implant-site infection rates, and implant failure rates leading to reduced time in hospital beds, less use of antibiotics, and fewer revision surgeries. Taken together, these benefits could improve survival rates, functionality and quality of life of bone cancer patients.” Other members of the team include the hospital’s Professor Adrian Gardner, director of research and development and Mr Jonathan Stevenson, orthopaedic oncology and arthroplasty consultant, Dr Eirini Theodosiou from Aston University and Professor Joao Lopes from the Brazilian Aeronautics Institute of Technology.

Legality, Next Steps for Canadian Tariffs
Maurice A. Deane School of Law at Hofstra University Professor Julian Ku was quoted in The Globe and Mail article “The best hope for Canada in fighting a trade war with Trump may lie in U.S. courts." “Using IEEPA to impose tariffs has not been done before, so there has never been a court ruling on this question,” said Julian Ku, who studies the interaction of international law and U.S. constitutional law at Hofstra University. Mr. Trump has, however, argued that he is responding to external threats, citing the movement of fentanyl and illegal migrants to the U.S. from Canada, Mexico and China. That is likely to prove a potent defense, Prof. Ku said. “The court has also been deferential to the President on national-security matters, and the language of the statute is very broad, so it is far from clear which way the court would come down on this issue,” he said.
