[1] The Pioneer core complex (PCC) in central Idaho lies along a transition between Early Eocene and ca. ≤40 Ma core complexes to the north and south, respectively. Thus, the age of extensional development of the PCC is important in understanding the spatial-temporal patterns of core-complex development in the North American Cordillera. New results, including structural observations and U-Pb zircon (SHRIMP and ICPMS) geochronology, constrain the early extensional history of the footwall for the first time. High-temperature strain with a top-WNW shear-sense is pervasive throughout metamorphic rocks of the northwestern footwall. An isoclinally folded dike yields a crystallization age of $48-47 Ma, whereas a crosscutting dike yielded an age of 46 Ma. Metamorphic rocks are also intruded by the $50-48 Ma Pioneer intrusive suite (PIS), a W-dipping granodiorite sheet displaying a magmatic fabric. Northwest-trending lineations are locally visible and also defined by anisotropy of magnetic susceptibility, indicating that during emplacement, the PIS was undergoing similarly oriented extensional strain as the enclosing metamorphic rocks. Therefore, WNW-directed extension spanning this structural section occurred between $50 and 46 Ma. Following emplacement of crosscutting 46 Ma dikes, deformation was partitioned into the WNW-directed Wildhorse detachment. Motion on the detachment occurred between $38 and 33 Ma, as documented by previous 40 Ar/ 39 Ar thermochronology. It is not clear, however, whether extension was continuous through the interval between these two time periods. Although Early Eocene extension in the PCC was synchronous with extension in core complexes to the north, rates of footwall exhumation in central Idaho were much lower. This southward slowing is compatible with N-S differences in inferred subduction zone geometry/kinematics and in the internal character of the orogenic wedge.

As the number of people living with chronic diseases climbs upward, novel methods to address the root causes of these disease are necessary to transform the state of our nation's health and our health care system. Interventions directed at making lasting lifestyle changes can have a major impact on the overall health of patients. In this pilot study, 4 obese patients, with unhealthy habits and abnormal blood profiles and biometrics, were able to significantly improve their lifestyles and their lab values with the 3-month intervention of a lifestyle medicine team, including a physician trained in lifestyle medicine, a certified wellness coach, a licensed nutrition specialist, a physical therapist, and a licensed mental health professional. Two patients had type 2 diabetes, and all 4 were hypertensive (blood pressure > 120/80 mm Hg). After the intervention, all improved their nutrition and increased their physical activity. In addition, all experienced improvements in lipid counts, blood pressure, weight loss, and cholesterol. The diabetic patients' levels of hemoglobin A1C dropped to normal. These successes show the benefits of a lifestyle medicine team approach.
