Mind[set]fulness: How Can I Control My Brain?

This unit aims to support students and teachers in developing a better understanding of growth mindset. While previous understandings of the brain posited that it was a static device with a fixed capacity for learning, growth, and talent, newer findings suggest that this is not the case. When faced with new challenges, learning opportunities, and even failures, the brain will forge new neural pathways. This unit explores the concept of neuroplasticity, the malleability of the brain, and explicit instruction on what power we have to rewire our thinking and behavior patterns. This unit also explores mindfulness as one such practice that can help students analyze and regulate their emotions and their response to stress

Swift observations of the X-ray and UV evolution of V2491 Cyg (Nova Cyg 2008 No. 2)

We present extensive, high-density Swift observations of V2491 Cyg (Nova Cyg 2008 No. 2). Observing the X-ray emission from only one day after the nova discovery, the source is followed through the initial brightening, the Super-Soft Source phase and back to the pre-outburst flux level. The evolution of the spectrum throughout the outburst is demonstrated. The UV and X-ray light-curves follow very different paths, although changes occur in them around the same times, indicating a link between the bands. Flickering in the late-time X-ray data indicates the resumption of accretion. We show that if the white dwarf is magnetic, it would be among the most magnetic known; the lack of a periodic signal in our later data argues against a magnetic white dwarf, however. We also discuss the possibility that V2491 Cyg is a recurrent nova, providing recurrence timescale estimates.Comment: 12 pages, 8 figure (2 in colour), accepted for publication in MNRA

One-Step Conversion of Potassium Organotrifluoroborates to Metal Organoborohydrides

This letter describes the one-step conversion of heteroatom-substituted potassium organotrifluoroborates (KRBF₃) to metal monoorgano­borohydrides (MRBH₃) using alkali metal aluminum hydrides. The method tolerates a variety of functional groups, expanding MRBH₃ diversity. Hydride removal with Me₃SiCl in the presence of dimethyl­aminopyridine (DMAP) affords the organoborane·DMAP (RBH₂·DMAP) adducts
