Navigating Disease-Modifying Treatments for Alzheimer's Disease: Focusing on Medications in Phase 3 Clinical Trials.

Over the past 18 months, there has been scrutiny and controversy over the U.S. Food and Drug Administration's accelerated approval of aducanumab, a novel monoclonal antibody to treat Alzheimer's disease and prevent disease progression.

Extending the Hoyle-State Paradigm to ^{12}C+^{12}C Fusion.

Carbon burning is a key step in the evolution of massive stars, Type 1a supernovae and superbursts in x-ray binary systems. Determining the ^{12}C+^{12}C fusion cross section at relevant energies by extrapolation of direct measurements is challenging due to resonances at and below the Coulomb barrier. A study of the ^{24}Mg(α,α^{'})^{24}Mg reaction has identified several 0^{+} states in ^{24}Mg, close to the ^{12}C+^{12}C threshold, which predominantly decay to ^{20}Ne(ground state)+α.

Angular momentum generation in nuclear fission.

When a heavy atomic nucleus splits (fission), the resulting fragments are observed to emerge spinning; this phenomenon has been a mystery in nuclear physics for over 40 years. The internal generation of typically six or seven units of angular momentum in each fragment is particularly puzzling for systems that start with zero, or almost zero, spin. There are currently no experimental observations that enable decisive discrimination between the many competing theories for the mechanism that generates the angular momentum.

An Interdisciplinary Approach to Implementing the Age-Friendly Health System 4Ms in an Ambulatory Clinical Pathway With a Focus on Medication Safety.

MedStar's Center for Successful Aging (CSA) participated in the Age-Friendly Health Systems initiative led by The John A. Hartford Foundation and the Institute for Healthcare Improvement in partnership with the American Hospital Association and the Catholic Health Association of the United States. This initiative focuses on bringing the 4Ms framework-What Matters, Medication, Mentation, and Mobility-to caring for older adults.

Advances in the Direct Study of Carbon Burning in Massive Stars.

The ^{12}C+^{12}C fusion reaction plays a critical role in the evolution of massive stars and also strongly impacts various explosive astrophysical scenarios. The presence of resonances in this reaction at energies around and below the Coulomb barrier makes it impossible to carry out a simple extrapolation down to the Gamow window-the energy regime relevant to carbon burning in massive stars. The ^{12}C+^{12}C system forms a unique laboratory for challenging the contemporary picture of deep sub-barrier fusion (possible sub-barrier hindrance) and its interplay with nuclear structure (sub-barrier resonances).
