The Whiteboard Revolution: Illuminating Science Communication in the Digital Age.

Journal-based science communication is not accessible or comprehensible to a general public curious about science and eager for the next wave of scientific innovation. We propose an alternative medium for scientists to communicate their work to the general public in an engaging and digestible way through the use of whiteboard videos. We describe the process of producing science whiteboard videos and the benefits and challenges therein.

Autonomic Dysreflexia After Hip Fractures Managed by Regional Anesthesia: A Case Report.

Autonomic dysreflexia occurs after a spinal cord injury usually at the level of T6 or above, and its hallmark feature is exaggerated autonomic response to noxious stimuli resulting in uncontrolled hypertensive episodes with reflexive bradycardia that can be fatal if not controlled. We present a case highlighting regional anesthetic techniques, including peripheral nerve blocks, to ameliorate the symptoms of autonomic dysreflexia triggered by hip fractures in a 57-year-old woman with an old C5-C6 spinal cord injury before definitive hip surgery. The regional techniques described provide anesthesiologists with a simple strategy to potentially mitigate a life-threatening situation.

Shaken, not stirred: collapsing a peptoid monolayer to produce free-floating, stable nanosheets.

Two-dimensional nanomaterials play a critical role in biology (e.g., lipid bilayers) and electronics (e.g., graphene) but are difficult to directly synthesize with a high level of precision. Peptoid nanosheet bilayers are a versatile synthetic platform for constructing multifunctional, precisely ordered two-dimensional nanostructures. Here we show that nanosheet formation occurs through an unusual monolayer intermediate at the air-water interface. Lateral compression of a self-assembled peptoid monolayer beyond a critical collapse pressure results in the irreversible production of nanosheets. An unusual thermodynamic cycle is employed on a preparative scale, where mechanical energy is used to buckle an intermediate monolayer into a more stable nanosheet. Detailed physical studies of the monolayer-compression mechanism revealed a simple preparative technique to produce nanosheets in 95% overall yield by cyclical monolayer compressions in a rotating closed vial. Compression of monolayers into stable, free-floating products may be a general and preparative approach to access 2D nanomaterials.
