Increased Lyα Opacity in White Dwarf Photospheres from Transient H− Resonances

open access: yesThe Astrophysical Journal
The structure and emergent flux of hydrogen atmosphere white dwarfs depend on the opacity of the Ly α and Ly β spectral lines. The opacity here is set by the strength and broadening of these lines; the latter is dictated by the far line wing, which is in

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Globalização sexual e seus potenciais criativos: etnias, (trans)sexualidades e “pop-stars”

open access: yes, 2016
Usualmente, na Sociologia, a globalização é tratada como uma série de desafios econômicos, culturais e políticos protagonizados por Estados, corporações transnacionais e fluxos de capitais e de informações, costumando ser retratada apenas enquanto ...

Biophysical approaches for studying viral entry

open access: yesFEBS Letters, EarlyView.
Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the

Ships, Clocks and Stars: The Quest for Longitude

open access: yes, 2014
The National Maritime Museum’s 2014 Ships, Clocks & Stars exhibition told the extraordinary story of the race to determine longitude at sea. Marking the 300th anniversary of the passing of the Longitude Act in July 1714, Ships, Clocks & Stars - which ...

The human gut microbiome across the life course

open access: yesFEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

A DRAMATURGIA DO ATOR E DA ATRIZ COMO FERRAMENTA PEDAGÓGICA

open access: yesRevista Rascunhos - Caminhos da Pesquisa em Artes Cênicas
This paper presents Eugenio Barba's concept of the actor's (and actress's) dramaturgy as a pedagogical tool for the development of theatrical skills, where the expedients of stage production are not only intended for creation, but also for learning the ...

Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

open access: yesFEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...
