Investigating stress-induced mitochondrial dysfunction and its role in systemic health

Metabolic stress is a common occurrence for active-duty military service members.  It occurs during periods of sustained physiologic challenges such as continuous physical activity, thermal stress, severe caloric deficits and sleep deprivation, which warfighters routinely experience. These stressors, both on their own and in combination, eventually lead to metabolic dysfunction, which can degrade a warfighter’s operational performance. HMC Research Scientist Zachary Graham has a new three-year Air Force Office of Scientific Research grant to gain a better understanding of stress-induced mitochondrial dysfunction. Mitochondria are specialized, double-membrane structures within cells that serve as the primary source of energy production. They are often referred to as the powerhouses of the cell. In addition to regulating energy metabolism, mitochondria also regulate controlled cell death, called apoptosis. They also can drive a cellular pro-inflammatory environment when normal function is compromised. Dysfunctional mitochondria create excessive reactive oxygen and nitrogen species (ROS/RNS) that can damage proteins, lipids and DNA/RNA; these changes also activate inflammation. Gaining a better understanding of mitochondria and their role in stress-induced mitochondrial dysfunction can provide critical insights into the sources of cellular energy as well as breakdowns of cellular energy. Graham, who has been at IHMC for the past five years, primarily… Read More

IHMC studies the potential of exoskeletons to reduce the biomechanical injuries shipyard workers face

When Jared Li started to study shipyard workers, he didn’t know much the work they did on a daily basis, except that the work was heavily manual and required working through tight and hazardous spaces. He also noticed that much of the work involved bending, lifting, and holding tools for extended periods of time (welding, drilling, grinding, etc.), especially with arms outstretched. Li, who leads the exoskeleton research at IHMC, wondered if exoskeletons might be a good fit for shipyard workers. Li’s work is focused on finding real-world applications for the technology. “It became clear to me that the shipbuilding industry was heavily affected by overuse injuries,” said Li. “I started thinking that perhaps the work we do with exoskeletons here at IHMC might be able to ease some of the biomechanical issues the workers face. Just imagine someone who is holding up their arms and welding long periods of time. That puts a lot of strain on the shoulders and the back – so a shoulder-focused exoskeleton could probably help offload that strain on the shoulder muscles. At least, that was my thinking.” So, Li reached out to Austal USA, a subsidiary of the Australian-based shipbuilding company Austal that… Read More

A Q&A With IHMC’s new CEO, Dr. Timothy Broderick

  In October, when Dr. Timothy Broderick took over as IHMC’s new CEO, he became just the third person to hold the CEO title since IHMC’s founding in 1990. Broderick took over for Dr. Morley Stone, who stepped away as CEO to lead an Air Force spin-out company he helped found, Mined XAI. Stone replaced Dr. Ken Ford, IHMC’s founder wh o spent 34 years as the institute’s leader and CEO before transitioning into an emeritus role. Broderick is hardly new to IHMC. He joined the institute eight years ago as Chief Science Officer and Senior Research Scientist, to shape research strategy and lead high-impact research focused on enhancing human health and performance in extreme environments. His path to IHMC- and now to its top leadership position- has not been a straight line. A practicing academic surgeon by training, Broderick has spent much of his career working at the convergence of medicine, science and emerging technologies. Before joining IHMC, he served as a program manager at the Defense Advanced Research Projects Agency (DARPA), where he conceived and established biotechnology programs focused on the diagnosis and treatment of military-relevant disease and injury. Earlier, he served as program manager at the U.S. Army… Read More

Centering the Human in AI Decision Making

IHMC, in collaboration with Carnegie Mellon University, has developed a new AI, but it’s not a Large Language Model; it doesn’t need a data center; and you can’t talk to it. Yet. In the DARPA-funded project MIMIR (Metacognitive Intelligence Maneuvers for Influence and Resolution), Dr. Ian Perera, with co-Principal Investigators Dr. Matt Johnson and Dr. Mark Orr, leads a team of researchers in building an AI system that rapidly learns to make decisions and, perhaps more importantly, learns how we as humans make them. Leaving data-hungry methods behind, MIMIR advances the IHMC mission of centering the human in the AI decision-making process, while paving the way to systems that learn to explore the world without very much input from us at all. If you want to find an answer to a question, solve a common problem, reorganize a document, or write a program, you probably will still use a Large Language Model, or LLM. But the MIMIR team is targeting different kinds of problems – those where the data is sparse, complex, and the best strategy is dynamic and responsive to changing environments or conditions. Think cybersecurity, disaster response, negotiations – domains where human expertise is immensely valued but difficult… Read More

Investigating exercise’s potential to reverse hallmarks of aging

What if you could reduce risk of mortality from any cause by 13, 26, or 39 percent? Researchers at IHMC think it’s not only possible, but well within reach of people in their sixties who are willing to invest in three days a week of combined endurance exercise training and resistance training. As people age and reach their sixties, their risk of all-cause mortality spikes. Seniors are more susceptible to deaths from heart disease, strokes, cancer, dementia, and traffic accidents. Plus, as people age and allow themselves to become frail, they are more susceptible to accidental falls, which are the leading cause of injury-related death among people 65 and older, according to the Centers for Disease Control and Prevention. Dr. Marcas Bamman and his colleagues at IHMC are in the midst of a NIH-sponsored clinical trial that’s designed to demonstrate exercise’s potential to slow down and even reverse the hallmarks of aging that contribute to all-cause mortality. Called Multidimensional Modeling to Maximize Adaptations to Exercise (M³AX), the clinical trial is in the third year of a five-year study that aims to provide evidence of exercise’s ability to improve the healthspan and quality of life of people over 59 years old….

Alex wins Army’s xTechHumanoid competition

IHMC and its humanoid robot Alex won the demonstration stage of the U.S. Army’s xTechHumanoid competition that was held at the Marine Corps Base Quantico in Virginia. More than a hundred companies and institutes submitted proposals for the opportunity to demonstrate their humanoid technology to the U.S. military. Based on the papers that were submitted, the Army selected 10 organizations to travel to  Quantico to demonstrate the capabilities of their humanoid robots. IHMC’s Alex stood out for its hybrid autonomy, which combines AI decision-making with human-operator control to perform complex missions. IHMC and four other organizations now advance to a structured evaluation phase where they will further demonstrate how their technologies can operate in complex environments that would otherwise put humans at risk. The final phase also includes an opportunity to secure a prototype evaluation contract with the U.S. Army. “It was great that out of more than 100 submissions we were selected as one of the top 10,” said Robert Griffin, a Senior Research Scientist who leads IHMC’s robotics group. “And, of course, we are all thrilled that we won the finals of the competition. Now we move on to an evaluation stage where we get to show how… Read More

IHMC’s new humanoid Alex aces its first off-site, off-tether demonstration

IHMC’s robotics team has just completed an off-site demonstration of its newly developed humanoid robot, Alex. “Things went really well,” said Senior Research Scientist Robert Griffin. “I believe the Office of Naval Research was impressed by the progress we’ve made over the past 10 months.” The Office of Naval Research (ONR) awarded IHMC a multi-year and multimillion-dollar contract to develop a robot capable of offsite and outdoor urban operations. The goal for Alex and its successors is to be nimble enough to operate in extreme environments, especially those involving military scenarios and disaster response where the risk for human casualty and injury is extremely high. “We are designing Alex so it will be able to walk up to a building, open a door, and walk around inside to assess a situation. The first soldier or responder who enters a building or warehouse is at a very high-risk of casualty. With Alex, our robot will be able to enter and assess these hazardous environments where human entry is extremely dangerous,” said Griffin. Lessons the robotics team gleaned from its work with Nadia have been incorporated into Alex. Nadia is an IHMC  humanoid that advanced the robotics field and gained YouTube notoriety… Read More

A Letter From Our CEO

At IHMC, we are all about advancing the human condition and, as such, excited to bring you a more dynamic digital newsletter that will provide the most up-to-date information about the exciting work that goes on here at the institute. With this new format for the newsletter, we will be able to incorporate multimedia to better bring our research to life. For example, you will not only be able to read about our ground-breaking work, but also view videos of our research in action. In early April at our annual open house, IHMC’s robotics team unveiled Alex, our new advanced humanoid robot designed to step out of the lab and into real-world environments. The open house was the first opportunity for the public to meet and observe Alex. Just recently, our robotics group took Alex on the road for the first time for a demonstration before the Office of Naval Research, which awarded the institute a multi-year, multi-million-dollar contract to develop the next-generation humanoid robot. Even now, the most advanced humanoids are designed for the structured environments of labs and warehouses where they perform repetitive tasks that are simple compared to the demands of real-world environments and their changing conditions….

IHMC project helps pioneer new tools for warfighters

The Russian-Ukrainian War has evolved over the past four years into the world’s first drone military conflict. Ukraine turned to inexpensive off-the-shelf drones at the beginning of the war to combat Russia’s larger and better-equipped army. The off-the-shelf drones were so effective at tracking Russian troops and bombing enemy targets that Ukraine quickly created manufacturing assembly lines capable of producing a million drones a year. With support from the U.S., Ukraine began innovating the use of unmanned aerial vehicles (UAVs) that led to a new generation of sophisticated drones that have rapidly transformed the nature of warfare. These innovations in autonomous systems are now being deployed in Iran. As a result of the military conflicts in Ukraine and Iran, new technologies in drones and autonomous systems are being rolled out around the world at an unprecedented pace. To help pioneer new capabilities, IHMC launched a project called Workbench four years ago. It allows the US military to prototype new concepts and rapidly develop new tools and technologies for warfighters that could be deployed in the battlefield. Over the last four years, Workbench has expanded far beyond its original mission. “We’ve grown a lot over the last four years,” says Matt… Read More

STEM-Talk: Doug Cooke talks about strengths and flaws of NASA’s Artemis mission

Four days after the astronauts of NASA’s Artemis II mission splashed down in the Pacific, STEM-Talk host Dr. Ken Ford interviewed Doug Cooke, an aerospace consultant who spent 38 years at NASA’s Johnson Space Center in Houston and NASA Headquarters in Washington, D.C. Ford, IHMC founder and a former Associate Director of NASA’s Center of Excellence in Information Technology, talked to Cooke about the Artemis mission’s 10-day roundtrip from the Earth to the Moon as well as NASA’s plans to return humans to the lunar surface by 2028. During his 38 years at NASA, Cooke played critical roles in the Space Shuttle, International Space Station and many other spaceflight programs. During the last three years of his NASA career, he served as Associate Administrator of the Exploration Systems Mission Directorate, which oversees the development of systems critical to NASA’s plans for human exploration of the Moon and Mars, including the Artemis program. Several times in his career, Doug served under Dr. Mike Griffin, our guest on episode 189, who served in a variety of senior leadership roles, including NASA Administrator. Mike and his colleague Dr. Lisa Porter shared their concerns in episode 189 that NASA’s Artemis program is seriously flawed… Read More

IHMC hosts national workshop on collaborative autonomy

The nature of military conflicts has changed. In the past, drones and unmanned systems had a small impact. But as we are seeing in Iran and Ukraine, unmanned systems are now having a dominant impact. “It shouldn’t come as a surprise that drones and other unmanned autonomous systems are having a bigger impact than they did 10 years ago,” says IHMC Senior Research Scientist Matt Johnson. “It also should not be a surprise that if you can scale unmanned systems better, you will have a significant advantage in future conflicts.” The problem in terms of military conflicts is that each drone or unmanned platform is operated by one war fighter, says Niranjan Suri, a Senior Research Scientist and Associate Director at IHMC. “Right now, there’s typically one war fighter in the field driving one drone. But if you talk to people in Ukraine, they would like to launch 100,000 drones at the same time. The problem is they don’t have 100,000 pilots. This is why we need to get where a war fighter is not commanding a single unmanned autonomous vehicle, but commanding a whole fleet of drones and autonomous systems.” This in a nutshell is what IHMC’s newly created… Read More

Community turnout lifts IHMC clinical trial to a great start

Dr. Marcas Bamman likes to think of exercise as a miracle drug. “I’ve long believed that we need to leverage exercise as a true form of medicine,” says Bamman, a Senior Research Scientist at IHMC and Director of the Institute’s lab for Healthspan, Resilience and Performance Research. “If we could bottle exercise into a pill, it would be a miracle drug.” Right now, with Pensacola’s help, Bamman and his colleagues at IHMC are in the midst of a clinical trial designed to demonstrate exercise’s potential to slow down and even reverse the hallmarks of aging.  Called Multidimensional Modeling to Maximize Adaptations to Exercise (M³AX), the clinical trial aims to provide evidence of exercise’s ability to improve the healthspan and quality of life of people ages 60 and older. Over a 30-year career, Bamman has been involved in healthspan studies and clinical trials around the world.  He has worked to provide physicians and health-care providers with the evidence they need to leverage exercise as medicine.  The M³AX trial that’s underway is a good example and it’s off to a great start thanks to the turnout and interest of Pensacola and the surrounding communities. “Our clinical trials are typically pretty demanding for… Read More
