Fundamental Laws of Biology Program Manager: Dr. Benjamin Mann Biology encompasses a vast array of interconnected phenomena spanning many decades in spatiotemporal scale. Every biological system, whether as complicated as the human body or as simple as a virus, exists within and interacts in a complex way with a complex environment. This implies that characterization of even simple biological systems can only be accomplished through acquisition of enormous data sets, built through observations within a coordinate space of very high dimensionality. The Fundamental Laws of Biology (FunBio) Program has assembled a well-balanced team of biologists, mathematicians, and physicists to develop a synergistic community and common language to — bring new mathematical perspectives to biology, use the stimulus of those challenges to create new mathematics that will reveal unanticipated structures in large complex systems, explain biological organization at multiple scales, and discover the fundamental laws of biology that span all biological scales. The initial phase of the Program focuses on identifying key fundamental problems in biology and promising innovative mathematical techniques to approach these problems. Later phases will translate this new mathematical language into testable theories of biological phenomenon with the goal of establishing fundamental, predictive laws of biology. The Program will impact DoD and national security by developing a rational and predictive basis for doing biological research to combat bioterrorism, maintain healthy personnel, and discover new vaccines and medicines
Human-Assisted Neural Devices Program Manager: COL Geoffrey Ling, M.D., Ph.D. The Human-Assisted Neural Devices (HAND) Program is developing the fundamental research basis to enable the use of brain activity to provide closed loop (motor commands out, sensor feedback in) for prosthetic devices. Additional technical challenges include methods for non-invasive sensors of brain activity and approaches for inputting sensory feedback into the nervous system. This program will also include new methods, processes, and instrumentation for accessing neural codes either through peripheral nerves or non-invasively at appropriate spatiotemporal resolution. Other aspects of the program examine memory storage as a means for improving learning and training. This fundamental research effort has formed the basis for establishing a new program in Revolutionizing Prosthetics that will incorporate advanced materials, actuation, and a power concept with neural control and sensory feedback to create a dramatically improved artificial limb for military amputees.
Improving Warfighter Information Intake Under Stress (AugCog) Program Manager: Dr. Amy Kruse Military operators frequently encounter complex computer-based interactive environments. It has been demonstrated that during times of significant stress the warfighter’s ability to process information is compromised. The AugCog Program seeks to enhance operational effectiveness by developing technologies capable of extending the information management capacity of the warfighter. This will be accomplished by developing a closed loop computational system in which the computeradapts to the state of the warfighter to significantly improve performance. Program objectives include adaptive strategies that will mitigate specific information processing bottlenecks that are roadblocks to increased performance and information flow. Strategies include— Intelligent interruption to improve limited working memory. Attention management to improve focus during complex tasks. Cued memory retrieval to improve situational awareness and context recovery. Modality switching (i.e., audio, visual) to increase information throughput. These technologies have the potential to enhance operational capability currently beyond reach (e.g., the control of multiple entities by one operator), support the reduction in the numbers of persons required to perform current functions, and improve human performance in stressful operational environments.
Intelligent Multi-modal Volume Angio Computed Tomography Program Manager: Dr. Joseph Mangano The purpose of the Intelligent Multi-modal Volume Angio Computed Tomography (IM-VAC) Program is to create a digital imaging system that is capable of performing a total body scan of a person using the multiple scanning techniques of computed tomography (CT), Positron EmissionTomography (PET), and Single Positron Emission Tomography (SPECT) on a single detector. Such a capability will be able to produce a single image that represents both anatomic (CT scan) and functional (PET and SPECT scans) information about the person in an image that will be automatically registered (data fusion) from the single detector plate. This capability will provide revolutionary new insight into the functioning of the human body as well as provide patient-specific (and soldier-specific) information in treating injury or disease. The first critical tasks of this effort are to develop the multi-modal detector capable of acquiring all three modalities and integrating the detector into a rapid scanning system to provide images in less than a minute
Preventing Sleep Deprivation Program Manager: Dr. Amy Kruse Sleep deprivation is a fact of modern combat. Current operations depend upon the warfighter’s ability to function for extended periods of time without adequate sleep. The widespread operational demand for optimal performance in sleep-deprivingconditions demonstrates the necessity for development of methods to safely combat sleep deprivation and to prevent the associated degradation of performance. The goal of the Preventing Sleep Deprivation Program is to define and implement approaches to prevent the harmful effects of sleep deprivation, and to provide methods for recovery of function with particular emphasis on cognitive and psychomotor impairments. Among the approaches currently under investigation include novel pharmaceuticals that enhance neural transmission, nutraceuticals that promote neurogenesis, cognitive training, and devices such as transcranial magnetic stimulation. The approaches discovered in this program will greatly increase our soldiers’ ability to function more safely and effectively despite the prolonged wakefulness inherent in current operations.
Peak Soldier Performance Program Manager: Dr. Brett Girior The goal of this program is create technologies that allow the warfighter to maintain peak physical and cognitive performance despite the harsh battlefield environment. The program currently has several areas of interest including tolerance to extreme climates (heat and cold), improved nutrients and supplements to support the physical stresses of combat, as well as broad basic science explorations into the biochemical etiology of muscle fatigue. In addition, the program will determine whether it is possible, and then beneficial, to provide highly customized vitamins based on each individual’s unique metabolism. This program, now in its last phase, has had numerous successes. In the area of thermoregulation, the investigators have developed a novel device for core body cooling/warming based on efficient heat transfer from evolutionarily conserved arterio-venous anastomoses in the palms and soles. In addition, the program has identified several candidate nutrients with important effects on mitochondrial metabolism and biogenesis. In preliminary laboratory experiments, these nutrients improve the content and efficiency of mitochondria following short term dietary supplementation. The effects of these nutrients are now being validated in randomized, double blind, controlled clinical studies. Perhaps most importantly, the program has recently identified a key biomolecule that is altered by stress, and may be causative for muscle fatigue following rigorous exercise. Overall, this program seeks to develop safe and effective methods to maintain combat performance under the stressful conditions of combat, and to enhance the basic science foundation so that additional important breakthroughs might be catalyzed once the program is complete.
Restorative Injury Repair Program Manager: Dr. Jon Mogford The vision for the Restorative Injury Repair (RIR) Program is to fully restore the function of complex tissue (muscle, nerves, skin, etc.) after traumatic injury on the battlefield. These injuries include both kinetic (i.e., penetrating wounds) as well as other destructive injuries (chemical and thermal burns, musculoskeletal injuries, blast overpressure, etc.). RIR aims to replace the current concepts of “wound coverage” by fibrosis and scarring with true “wound healing” by regeneration of fully differentiated, functional tissue. The program will achieve its goals by developing a comprehensive understanding of the wound environment, including cellular elements, matrix, inflammatory mediators, growth factors, nutrients, substrate utilization, biofilms, and ultimately processes of morphogenesis leading to anatomic and functional restoration. This is an extremely aggressive, milestone-driven program, with a Phase 1 effort focused on defining the wound environment and generating a blastema in an otherwise non-regenerating animal. This will be followed by a Phase 2 effort, which will culminate in the restoration of a functional multi-tissue structure in a mammal.
