Pathobiology: How Disease Happens

How Hearing Happens

dustrial noise, airplanes, subways, and putative music. Research on the auditory system has come of age. AlThis hearing loss is ordinarily permanent, for cochlear though hearing lacks some of the simplifying features hair cells are not replaced by mitotic turnover. Although that made vision the original paradigm for neurobiologicochlear prostheses have now restored partial hearing cal research,...

Rethinking How Hearing Happens

Inner ear hair cells convert hair bundle deflection into mechanical force sensed by ion channels via extracellular tip links between adjacent stereocilia. In this Neuron issue, Grillet and colleagues show the protein harmonin mechanically reinforces tip link upper insertion sites. Harmonin loss at this site reduces mechanotransduction kinetics and sensitivity.

Noah A . Smith . Ellipsis Happens , and Deletion Is How NOAH

I offer an overview of recent literature on ellipsis phenomena in natural language, including the most salient empirical arguments surrounding the classification of ellipsis as a phenomenon of the Phonological Form or of the Logical Form. I show that the majority of evidence supports the view of ellipsis as PF-deletion rather than LF-copying. I then give a theoretical argument that supports thi...

Collaborative Learning: Students’ Perspectives on How Learning Happens

Collaborative learning (CL), a core component of inquiry-based learning approaches, aims to support students’ development of key skills (e.g., working in multidisciplinary teams). To design effective CL activities, we need to understand students’ perceptions about CL. However, few studies have examined students’ understandings of CL. This qualitative study aimed to address this gap by analyzing...
