Shared governance increases marine protected area effectiveness.

Marine protected areas (MPAs) are widely used to conserve and manage coastal resources. Protected areas are governed by a variety of institutional arrangements, yet little is known concerning the relative performance of different governance approaches. This research draws upon a unique dataset that combines details on the reported International Union for Conservation of Nature (IUCN) governance categories of 217 global MPAs and their ecological outcomes to compare the performance of alternative governance arrangements.

Securing Commercial Nucleic Acid Synthesis.

On-demand gene synthesis is a growing industry that has democratized access to customized synthetic deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) products used in biological research. However, the increasing availability and decreasing cost of custom synthetic nucleic acids presents a risk of misuse that could allow nefarious actors to obtain sequences of dangerous organisms or novel-engineered pathogens to construct a biological weapon. Securing nucleic acid synthesis is a policy priority for the U.

The management of critical bone defects: outcomes of a systematic approach.

Background: The reconstruction of segmental long bone defects remains one of 'The holy grails of orthopaedics'. The optimal treatment of which remains a topic of great debate. This study aimed to evaluate the outcomes following the management of critical-sized bone defects using a classification-based treatment algorithm.
