Game-changing treatment Eleven-year-old Hayden Thomas enjoys playing tennis with his sister Madilynn. He can even serve the ball, thanks in part to a novel exercise program incorporating use of a bodypowered 3D-printed prosthetic hand. Designed to help patients better manage everyday tasks, the program offers hope for more convenient, cost effective therapy options for children with congenital upper limb deficiencies. Hayden’s mom, physical therapist Amanda Thomas in the Nicole Wertheim College of Nursing & Health Sciences, and her Doctor of Physical Therapy students created the at-home program in which Hayden’s strength, range of motion and coordination improved markedly. His 3D-printed hand was created at FIU’s Miami Beach Urban Studios, and the pattern for the adult-sized hand was modified with assistance from university biomedical engineers. Thomas’s study has received global interest since its publication in the Journal of Hand Therapy.

Why do insects behave so bizarrely around light at night? As part of FIU’s global research collaborations, an international team provided a new explanation for a millennia-old mystery.

A combination of motion capture tech and high-speed cameras revealed an important clue: In flight, insects keep their back turned toward the light source. According to the data, published in Nature Communications, this is because they evolved to rely on the brightest thing they see (the sky) to know which way is “up” and maintain control in the air. Artificial light at night throws these instincts for a loop and insects get trapped in an exhausting cycle trying to stay orientated — a futile effort that causes clumsy maneuvers and occasional crashes directly into the light. This study received national and international coverage, appearing in The New York Times, CNN, Scientific American, The Guardian and more.

E X PE RIE N C E IM PAC T LAST FALL, FIU COMPLETED ITS LATEST STRATEGIC PLAN: EXPERIENCE IMPACT 2030. The process necessitated that we evaluate honestly our current state and our desired destination. It required a cleareyed assessment of strengths, weaknesses, opportunities and challenges, not only internally but in our community, region and beyond. Much like the last strategic plan, we knew this one must be relevant and position FIU and our students for long-term success. We knew that our next strategic plan must provide direction for the university community to move forward with clarity. As this stunning photo illustrates, moths lose their bearings around artificial light at night. Confusion reigns. We needed to make sure there was no confusion among our FIU community about where we were headed and how we were going to get there. Experience Impact 2030 is focused on expanding our accomplishments in student success, research excellence, national and international recognition, continued recognition as a leading Hispanic-Serving Institution, leadership in arts and culture, and dozens of leading initiatives addressing great challenges facing our global community. It presents an opportunity to continue our momentum and strategically redefine the role and impact of the public research university. As part of this 18-month collaboration that involved university leaders, faculty and staff, students, alumni and community leaders, FIU identified three strategic areas of research focus: Environment & Environmental Resilience, Health, and Technology & Innovation. This issue is filled with the important work of our researchers and students tackling critical issues in these focus areas and beyond. We highlight the work of a marine ecologist whose decades of research around predator-prey interactions and the ecological importance of sharks has yielded greater understanding of the role of these creatures in the ocean’s ecosystem. We offer a behind-the-scenes glimpse into a cancer researcher’s lab, in the process gaining a sense of what drives her and the members of her team. And we introduce our readers to some of the climate tech innovations being developed by our faculty and students. We hope you enjoy these articles and this publication.

Deadly naïveté Behold the slough crayfish (Procambarus fallax). Petite enough to fit in the palm of a hand, these freshwater crustaceans were once abundant in the Everglades and a plentiful food source for wading birds. But populations have plummeted 99% in the last decade. Invasive Asian swamp eels are the prime culprit behind the disappearances. Institute of Environment postdoctoral researcher and wildlife photographer Brandon A. Güell wants to understand why slough crayfish — who expertly evolved to fight, freeze or flee for survival — have become such easy prey. With video and timelapse photography, he documents neverbefore-seen predator-prey interactions in the lab. Most concerning: Crayfish act unusually nonchalant around the eels. They don’t use anti-predator tactics, like freezing or hiding, as they would to escape native predators. Güell says this is a sign of prey naïveté, the idea native species fail to “recognize” invasive predators as a threat because they didn’t coevolve and this could explain why the eels have the upper hand not just against the crayfish but potentially other species.

FTER HIV hijacks immune cells in the bloodstream, it breaks through the heavily guarded blood-brain barrier and targets

the brain’s immune cells. These cells then enter a hibernation period. Neuroinflammation can reactivate them, perpetuating a vicious cycle where HIV spreads out of the brain and into the body’s bloodstream. CBD’s anti-inflammatory effects may stop this process.

LLEGAL GOLD mining has ravaged the Amazon, wreaking havoc on the environment and contaminating waterways. Conservation crime scientist Stephen Pires and criminology

professor Rob Guerette from the Steven J. Green School of International & Public Affairs are connecting the dots to find out if it has also led to a rise in murders in the region. With prices skyrocketing, gold has become a lucrative business — even surpassing the price of cocaine. Criminal organizations and illegally armed groups want to control production. Although it’s well known illegally armed groups are willing to fight and kill for access to precious resources, there’s been few studies to make a clear connection. Pires’s data is the first to show that areas with greater amounts of gold mining and coca production are directly associated with homicide hot spots in Colombia.

Raul Ruiz, director of FIU’s Bar Preparation Program, examined the theory, design, implementation and evaluation of what makes successful prep programs.

Instead, programs must focus on active learning that fosters the skillset it takes to be a lawyer — cognitive skills (thinking, reasoning, reading, learning, attention span and memory) and especially noncognitive or “soft skills” (behavior and mindset, like being open to experiences and putting in the effort).

ILLIAM E. PELHAM JR. spent his life transforming the lives of countless children and their families across the world. He passed away in October 2023.

For over four decades, the world-renowned child psychologist never stopped challenging popular assumptions or conducting evidence-based research. Pelham entered the field in the ’70s, when the mysteries of ADHD were still being unraveled and by the ’90s medications like Ritalin were being widely used. But could other interventions like behavioral therapy help them before they were given medication? That’s what Pelham devoted his life to finding out. Study after study, he began forming a new ADHD treatment approach where behavior therapy, including training for parents, was the first line of treatment. This led to new clinical guidelines issued by the Society for Developmental and Behavioral Pediatrics that recommends Pelham’s findings and is the foundation of today’s standard ADHD treatment. Over his career, Pelham authored nearly 500 peer-reviewed publications, received more than $100 million in grants and collaborated on many more grants as a co-investigator. Among his many awards, Pelham was recognized by the American Psychological Association and the Society for the Science of

Take out the trash The dopamine neuron in the cell model pictured here was full of trash. Autophagy, the built-in cellular house cleaning system, wasn’t working as it should to dispose of damaged, misfolded proteins. Too much alpha-synuclein had accumulated. This is the problem protein involved in Parkinson’s disease that clumps together, disrupts cell-to-cell communication and triggers neuronal death. Kim Tieu and researchers in his lab had doused cells with different concentrations of manganese (exposure to high levels is a risk factor for developing Parkinson’slike neurological symptoms). Even small amounts impaired autophagy, according to the study’s results published in Molecular Neurodegeneration — suggesting chronic exposure could contribute to neurodegeneration. Then they made a discovery with clinical implications: A partial block of dynamin- related protein-1 (Drp1) coaxed the cell’s clean-up process to take out the trash again, regardless of manganese exposure. With funding from a $6.6 million National Institute of Environmental Health Sciences’ Revolutionizing Innovative, Visionary Environmental Health Research (RIVER) grant, Tieu’s lab is collaborating with Scripps Research to identify FDAapproved compounds that target Drp1 for new Parkinson’s therapies.

Warning signs of an unhealthy heart, though, can lurk — not so quietly — in its many complex sounds. This invention “listens” for changes, providing a way to pinpoint markers of heart failure based on the frequency and durations of sounds in a cardiac cycle. Paired with an algorithm, it could open the door to more accessible, low-cost diagnostics for routine doctor’s visits or at-home style tests for earlier detection, diagnosis and better treatment outcomes.

In My View

The United States spends trillions annually on health care yet performs poorly in key health indicators. Hortensia Amaro, distinguished university professor and senior scholar for community health at the Herbert Wertheim College of Medicine and Robert Stempel College of Public Health & Social Work, explores factors driving the American health disadvantage in this issue’s “In My View” editorial. She is a member of FIU’s Population Health Initiative executive council. A member of the National Academy of Medicine, Amaro’s scholarship has advanced the understanding of gender and ethno-racial inequities in substance use disorders and co-occuring disorders treatment, HIV prevention and other urgent public health challenges. Prior to FIU, Amaro was an assistant vice provost and the first top-ranking Latina administrator at the University of Southern California, where she was also Dean’s Professor of public health and social work.

Workstations are painstakingly prepped, organized. Dinner orders, placed; hunger an unnecessary distraction to the work ahead. Anxiously, Azzam’s team waits. “Receiving a sample brings so many emotions,” Azzam admits. “We always remember there’s a person behind it, someone we may be able to help, so we’re filled with excitement and hope.”

To further investigate this gene-drug link, Azzam also heads a National Institute on Minority Health and Health Disparities funded project — as part of FIU’s Research Center in Minority Institutions (RCMI) — to use functional precision medicine to not only expand treatment options for minority pediatric cancer patients but also identify unique biomarkers common across different groups that can be targeted with specific FDA-approved drugs. “I’m particularly pleased that we will be providing our functional precision medicine approach to children with cancers that come from minority populations,” says Azzam. “These patients often don’t have access to these clinical trials.” FIU-RCMI is focused on world-class, community-partnered health disparities research and training. Since its inception, the center has supported, trained and mentored dozens of post-doctoral fellows, junior faculty and other earlystage investigators.

Promising new drug candidate for Alzheimer’s AMYLOID PLAQUES ARE A MAJOR focus of Alzheimer’s research and drug development efforts worldwide. But there’s another less understood hallmark of the disease, suspected to play an underlying role in its progression: chronic neuroinflammation. Could blocking these inflammatory waves ward off cognitive impairment? Through a promising new Alzheimer’s treatment discovery, Kyung Bo Kim has found an answer: Yes. Kim targeted the proteasome, the cellular process responsible for round-the-clock removal of specific proteins compromising cell survival. He previously helped create drugs that interfere with this process in cancer cells to destroy them, including FDA-approved anti-cancer medication carfilzomib. This time, Kim turned his attention to immunoproteasome, a special proteasome found in immune cells, and tied to inflammatory responses. Unusually high levels have been detected in the brains of people with Alzheimer’s disease. With funding from the National Institute on Aging, Kim identified immunoproteasome

Optimizing sleep health to improve mental health A ROTTEN NIGHT’S REST makes anyone moody. For kids, sleep problems can be a more serious precursor to anxiety and depression. As a researcher and clinician who helps adolescents struggling with these disorders, Dana McMakin wants to know if worrying at bedtime interferes with the brain’s routine ability to process and permanently store emotional memories during sleep. And if this, in turn, causes difficulty regulating emotions. To find out, she’s taking an up-close look inside anxious kids’ sleeping brains. At Nicklaus Children’s Hospital, McMakin’s leading a National Institute of Mental Health-funded project with FIU neuroscientist Aaron Mattfeld that’s following 200 kids with anxiety from 9-13 to 18 years of age. A combination of questionnaires, MRI scans and polysomnography — gold-standard technology that measures brain waves, eye movements and breathing — is providing a detailed picture into how exactly stress alters sleep physiology (i.e. REM sleep neurophysiology). Physiological differences are already emerging in the data. This data is critical to pinpointing the right interventions. McMakin’s also getting a new collaboration off the ground with Harvard and University of Pittsburgh researchers. The NIMH-supported Pediatric Precision Sleep Network aims to identify sleep “fingerprints” that could predict mental health risks during this pivotal developmental period and develop screening tools for primary care providers.

Of all the things that put you at risk for mental health problems — trauma, genetics, family environment — there’s a lot that’s hard to change. But sleep? It’s easy to modify. If we can find out what’s going on physiologically that impacts sleep, then we can pinpoint how and when to intervene. — Dana McMakin

3D-printed bone reconstruction for pediatric cancer patients DOCTORS SHARED THE CHALLENGES of helping their young patients with osteosarcoma, a type of bone cancer, with Anamika Prasad. In the majority of cases, treatment requires a highly complicated surgery to remove sections of tumor-riddled bone. Implants made of metal or other sturdy manmade materials can be a good replacement option for adults. But not kids with still-growing bones. Securing a limb could stunt its growth, resulting in one arm or leg becoming shorter than the other. Leveraging her background in materials science and civil engineering, Prasad is on a mission to find innovative solutions. She’s developing a unique ‘scaffold’ implant design adapted to children’s unique needs. Similar to temporary scaffolding that supports construction workers, these 3D-printed structures made of FDA-approved material will provide places for bone cells to cling and climb on, so they can build bone over time. Prasad works closely with Dr. Juan Prettel, chief of musculoskeletal oncology surgery at Baptist Health, on this research. With support from the Casey DeSantis Florida

Memories + history in music MUSIC HOLDS AS MUCH HISTORY as any written record or document in an archive. That’s especially true of fújì — a popular genre hailing from Saheed Aderinto’s native Nigeria. More than the danceable drumbeats distinguishing its unique sound, fújì carries the memories of millions of Yoruba people. It is the way they see the world, a way of life. As a leading social and cultural historian of modern Nigeria, Aderinto brings this important musical tradition to those who may have never even heard the word “fújì.” He’s traveled to Lagos, Ibadan and other cities, visiting libraries, museums and universities to interview different fújì artists. Everything he learned, Aderinto shared in realtime with his deeply engaged audience on social media — part of his commitment to make research accessible to all people. It also went into his forthcoming book Fúji: An African Popular Culture. But he’s not stopping there. The 2023 Dan David Prize winner, recognized for his outstanding contributions to history, continues to bridge the knowledge gap by venturing into what he calls a totally “different world” of visual storytelling. Aderinto directed and produced a multi-part documentary. It documents fújì’s emergence in the 1970s during Nigeria’s cultural and artistic revolution, the artists who defined its sound and performances that influenced other genres from hip-hip to gospel.

If people want healthy oceans, we need healthy shark populations in many of our marine ecosystems. — Michael Heithaus According to the research, this means shark conservation must go beyond simply protecting shark populations —

IT MUST PRIORITIZE PROTECTING THE ECOLOGICAL ROLES OF SHARKS.

Other roles of sharks (of a variety of sizes) include: moving nutrients that fertilize the base of the food web; serving as scratching posts for fish to remove parasites; and even small sharks serving as food for other species of sharks and killer whales. That means a variety of sharks are needed in ecosystems, yet their many and diverse contributions to ocean health are under threat from overfishing, climate change, habitat loss, energy mining, shipping activities and more. “When we look around the world, we see that sharks can play lots of different roles in ecosystems – and some of them are really important,” Heithaus said. “That means we need to maintain a diversity of sharks in our oceans as well as a wide range of sizes of sharks. It also means we need to be rebuilding heavily depleted populations and managing for how sharks will function in oceans that are changing due to human uses and climate change.”

“This study verifies what we’ve long suspected – sharks are critical to ocean health,” said Lee Crockett, executive director of the Shark Conservation Fund, which funded the study. “This landmark study serves as confirmation that marine conservationists, philanthropists, policymakers, and the public alike need to recognize that sharks are keystone species that have a now-proven significant effect on marine environments.” As the research puts a spotlight on the critical importance of sharks, the researchers also offer suggestions that could aid in protecting and restoring sharks’ functional roles. These include national and international policies to increase spatial measures like Marine Protected Areas. They also recommend fisheries management measures like catch/size limits and limitations on gear that is particularly harmful to sharks like gillnets and longlines. The publication of this research is a full-circle moment for Heithaus and what started with a chance introduction to the pristine waters of Shark Bay. “In those early days, we talked about the sharks a lot,” Connor said. “Our group had always been saying, the ecology of Shark Bay is incredible. More people should be here studying the other animals.” Today, Heithaus continues to expand his shark research, including collaborative efforts to fill data gaps. When he joined FIU as a faculty member in 2003, he was the lone shark researcher.

Genetic engineering + wildlife law THE RETURN OF THE LONG-EXTINCT wooly mammoth or dodo bird may sound like a storyline straight out of science fiction. It’s not. Several deextinction projects all share an ambitious aim to resurrect disappeared species. Impossible to create an exact clone of these long-gone creatures, scientists instead modify the DNA of living animals to resemble extinct ones. This same technique is also used in last-ditch conservation interventions for imperiled animals, like modifying the genes of coral to withstand warmer oceans. The new science marches forward. The law can’t keep up. Wildlife conservationist turned legal scholar Alex Erwin constructs the legal framework to begin to establish guidance and parameters around when genetic engineering would actually prove beneficial — not wasting time, resources, money and effort. For example, genetic tinkering might help an animal facing a deadly virus or plague, not necessarily one facing habitat destruction. At the intersection of law and science, Erwin’s nationally recognized scholarship focuses on the intersection between science and wildlife law. His recent work determined genetic engineering would be covered by the Endangered Species Act and that the existing law would provide regulatory oversight and authority to federal agencies. His article on the topic was selected for presentation at the prestigious Harvard/Stanford/Yale Junior Faculty Forum.

Quest for lifesaving perfume MOSQUITOES ARE THE DEADLIEST animals on the planet, killing hundreds of thousands of people every year through the spread of disease. Neurogeneticist Matthew DeGennaro is on the hunt for a lifesaving perfume. He’s the first scientist to make a mutant mosquito — a game-changing tool in researching mosquito behavior. Secured in his Tropical Genetics Lab, DeGennaro relies on his mutants to help answer globally critical questions like how mosquitoes find people. Because he can’t ask a mosquito, he removes a single gene to create a mutant and then observes its behavior. In 2019, DeGennaro unleashed a new era in mosquito prevention research when he, with the help of his students, identified the olfactory receptor mosquitoes rely on to detect people. His focus has now shifted to finding a scent to disrupt that receptor. DeGennaro’s research has provided other key insights including what goes into a mosquito’s decision of where to lay eggs and natural odors that could keep mosquitoes at bay.

Speech pathology CHELSEA SOMMER WANTS EVERY CHILD born with cleft palate to receive the care they deserve. The bilingual speech-language pathologist knows it can be challenging to obtain treatment for this complex congenital difference that is associated with speech development problems, even after surgery. Roughly 70% of children with cleft palate require speech therapy, however, there are some regions in the world with a shortage of speech therapists. A professor and craniofacial speech therapist at Nicklaus Children’s Hospital in Miami, Sommer knows a child who cannot be understood might be less likely to speak and be spoken to. Addressing the gap in care, she has been part of the development of a structured virtual cleft speech mentorship program with Smile Train for speech practitioners of all skill levels. Additionally, Sommer has traveled to Peru for the past three years to volunteer with the FACES Foundation, providing speech assessment and treatment to children with cleft palate. In other research, Sommer and colleagues at Johns Hopkins All Children’s Hospital are examining the validity of artificial intelligence in assessing hypernasality in patients with velopharyngeal dysfunction (VPD) – which occurs in about 20-30% of children with cleft palate after their palate repair. Sommer and her colleagues are investigating whether artificial intelligence could aid health care practitioners in making a diagnosis.

Each delicate fold and crevice is algorithmically shaped using computational codes, integrated with data from scientific journals — for example, the exact crevice sizes oysters prefer for habitat — to script and generate the ideal, most inviting homes for these essential filter-feeder species. Designs are then fabricated using cutting-edge robotic 3D printing to be attached seamlessly to existing seawalls. Pezeshk points out that future possibilities for Ecoblox are seemingly endless. She’s working on variations that are currently in development, including a SMARTE tile (Sensing and Monitoring for Aquatic Restoration, Tracking, and Evaluation) equipped with sensors that can monitor vital water quality parameters such as salinity, oxygen and pH levels, temperature, as well as other vital data. Sara Pezeshk and Shahin Vassigh — director of FIU’s Robotics and Digital Fabrication Lab — recently received new support from the EPA to further this work, and soon Ecoblox will be installed at several sites in Biscayne Bay for field testing.


Bolstering Infrastructure

ONVENTIONAL CONCRETE may be strong. But ultra-high

Introducing South Florida’s ClimateReady Tech Hub

performance concrete (UHPC) is five times stronger. “Just applying a shell of UHPC around a structure, like a bridge

column, adds to its total strength and makes it almost maintenance free for life,” explains Atorod Azizinamini, director of infrastructure, research and innovation at FIU and a leading bridge engineering expert who holds a patent for this UHPC shell framework concept. Made with a mix of durable materials like steel fibers and very fine sand (rather than standard aggregate like rocks or gravel) it’s become an ideal candidate for the 40,000+ U.S. bridges and other aging infrastructure in need of repair or maintenance. Another benefit: UHPC is saltwater resistant, making it perfectly suited for coastal structures prone to damaging corrosion. Azizinamini — along with the team he leads at the USDOT-funded Innovative Bridge Technologies/Accelerated Bridge Construction University Transportation Center (IBT/ABC-UTC) — currently explores new ways to maximize the advantages of UHPC through additive construction. One technique involves robotic equipment to create site-specific, 3D-printed structural pieces for retrofitting or reinforcement. Another is the use of UHPC in conjunction with pneumatic or “shotcrete” spraying. With funding from the U.S. Army Corps and IBT/ABC-UTC, Azizinamini developed an open source, cost-effective sprayable UHPC. It has a lower carbon footprint and life cycle cost while reducing application time and labor. In collaboration with the Northern Virginia District of the Virginia Department of Transportation, FIU’s UHPC was recently used for the first time to repair a bridge in the U.S.

Then-U.S. Assistant Secretary of Commerce for Economic Development Alejandra Y. Castillo visited FIU to make the nationwide announcement about funding for the South Florida ClimateReady Tech Hub.

SOUTH FLORIDA was selected to be the home of the nation’s climate-ready tech hub. It aims to advance sustainable and resilient infrastructure while scaling up the production and delivery of critical technologies that will strengthen America’s clean energy transition and national security. Of the $19 million in federal funding from the U.S. Department of Commerce’s Economic Development Administration, $10 million will go to FIU to support: • TECHNOLOGY DEVELOPMENT AND MATURATION Accelerate the readiness and expand deployment of cement technologies like FIU’s Ultra High Performance Concrete. • CLIMATE READY INFRASTRUCTURE INNOVATION CENTER Over the next five years, services and mentorship will be provided to at least 60 infrastructure innovation startups and small businesses. • INDUSTRY CODES AND STANDARDS FIU’s Wall of Wind (WoW), the only life-size test facility at a U.S. university capable of generating Category 5 winds, has led to improved codes and safer buildings. Now, NSF-funding will support the design of a new facility to test construction against 200 mph winds, combined with a water basin to simulate storm surge and wave action. All of this will help researchers continue to provide expertise and input for the improvement of building codes and standards, work on policies to incorporate new materials and technologies, as well as give regulators guidance on which standards to enforce and recommendations to streamline the approval process.

New energy generation and storage solutions

ATTERY ENERGY storage systems and renewable energy must “work together hand in hand,” says Daniela Radu, who researches nanomaterials for the next generation of solar cells

at FIU. “That’s how you get to energy zero.” This seamless integration is the goal of the Center of Excellence for Integrated Renewable Energy and Energy Storage. Established with a $10 million investment from the Department of Defense (DoD), FIU leads this multi-year project — that includes collaborators from Pennsylvania State University — to find new energy solutions that support DoD’s strategic commitment to making climate resilience a national security priority. “If you look at traditional solar panels, the first thing that comes to mind is they’re very heavy,” says Radu, the project’s principal investigator. “Soldiers carry a lot in the field, so imagine having to carry heavy solar panels and batteries on top of it. We’re aiming to create lightweight, foldable, portable alternatives.” Additionally, the researchers want to incorporate Earth crust elements that are more readily available in the U.S., like copper, while maximizing power conversion efficiency by capitalizing not just on photons in sunlight but any light source, including indoor light bulbs. All of this will connect to a microgrid. Unlike the traditional power grid that’s interconnected and delivers electricity to many homes or businesses, a microgrid acts independently or in “island” mode — especially important for soldiers often stationed in remote areas.

M

ICROGRID TECHNOLOGY is uniquely capable of protecting the reliability of our energy supply in the wake of extreme weather events such as wildfires

and hurricanes. As part of a decades-long effort to advance renewable energy technologies, FIU — in partnership with Florida Power & Light Company (FPL) — conducts ground-breaking research on the AI-based renewable microgrid installed at the university’s engineering center. The microgrid, installed by FPL in 2020, pairs reliability with clean energy production and leverages an on-site 1.1MW AC solar panel array to generate renewable power, as well as a 9MW/3MWh lithium-ion battery energy storage system with the equivalent energy capacity to power over 440 homes for up to three hours. “This research can help pave the road for providing local and global communities with increased resiliency for riding through extreme weather and power grid events,” says Arif Sarwat, principal investigator of the FIU-FPL microgrid and director of FIU’s Energy, Power and Sustainability-Intelligence research group. In addition to the solar and battery storage-based microgrid, researchers at FIU leverage the Proactive Analytics and Data Oriented Research on Availability and Security (PANDORAS) Lab, which serves as a virtual distribution system control room and is interconnected to a real-time simulation lab. There, faculty and students in Sarwat’s research group use high-end computer systems to conduct research and simulations using

Just like blood spatter can be analyzed, so too can shrapnel or an explosive pattern. Patterns such as injuries on victims, or things like shrapnel, crater damage and burn pattern still tell us much about the type of weaponry used. Injury and blast patterns over a group of people or a damaged site aren’t easily manufactured or faked.

Trucco tackles an escalating online problem with offline consequences: How social pressure on social media makes teens more likely to participate in popular challenges that can be dangerous and sometimes deadly.

Teens today may find it more difficult to resist social pressure. They not only have unlimited access to their peers and other influencers, but online social networks are also much larger, with teens following hundreds – sometimes thousands – of online users.

To conceive of what might happen, it is useful to recall the impact of the introduction of word processing programs in the early 1980s. Certain jobs like typist almost completely disappeared.

Splat! You’re cruising down the highway. Splat! A bug hits the windshield. The goopy remains smear across the glass. Even a few swipes of the wipers are no match for the stuck-on mess. In simple terms, this is exactly how cold spraying works, though the process is far more elegant. Sophisticated systems (like this VRC Raptor in the Cold Spray and Rapid Deposition Laboratory) blast microscopic powder particles onto surfaces at supersonic speeds. As the spray nozzle at the end of the robotic arm moves around, it builds layer-upon-layer of material. Unlike other types of manufacturing, there’s no melting involved in the process nor volatile fumes — making it a more environmentally friendly option for applying protective coatings or making repairs. Supported by $22.9 million from the U.S. Army Research Laboratory, FIU’s state-of-the-art lab gives researchers a place to push the boundaries of cold spray. To date, they’ve developed and patented dozens of new advanced materials, such as high-strength aluminum composites, that can be fabricated using this technology for applications in the aerospace, automotive and defense industries.
