News consumers expect news outlets to be objective and balanced in their reports of events and opinions. However, there is a growing body of evidence of bias in the media caused by underlying political and socio-economic viewpoints. Previous studies have tried to classify the partiality of the media, but there is little work on quantifying it, and less still on the nature of this partiality. Read More

Myosin Va is an actin-based motor molecule, one of a large family of unconventional myosins. In humans, mutations in MYO5A cause Griscelli syndrome type 1 and Elejalde syndrome, diseases characterized by pigmentation defects and the prepubescent onset of severe neurological deficits that ultimately lead to a shortened lifespan. Mutations in the Myo5a gene in mouse cause the dilute series of mouse mutants, demonstrating that myosin Va is involved in pigmentation and neural function. Read More

To achieve permanent results for the correction of a drooping nasal tip, it is important to understand the mechanism responsible for the caudal rotation of the tip when a person speaks or smiles. This mechanism can be considered to depend on a "functional unity" formed by three components: (1) the cartilaginous framework (alar cartilages and accessories acting as a single structure); (2) muscular motors (m. levator labii superioris alaeque nasi and depressor septi nasi); and (3) gliding areas (apertura piriformis, the valvular mechanism between the upper lateral cartilages and alar cartilages, the lax tissue of the nasal dorsum, and the membranous septum).
