Insights into a long life without cancer: The case of the bowhead whale

open access: yesMolecular Oncology, EarlyView.
Long‐lived, large‐bodied organisms have evolved powerful anticancer mechanisms that preserve cellular and tissue integrity across extended lifespans. A recent study by Firsanov et al. shows that greater genome stability is a key factor underlying the remarkable longevity and cancer resistance of one such species, the bowhead whale.

Molecular dynamics simulations of positively selected codons in FcγRI reveal novel biochemical binding properties

open access: yesFEBS Open Bio, EarlyView.
Evolutionary analysis across 32 placental mammals identified positive selection at residues H148 and W149 in the immune receptor FcγR1. Ancestral reconstruction combined with molecular dynamics simulations reveals how these mutations may influence receptor structure and dynamics, providing insight into the evolution of antibody recognition and immune ...

Assessing Inhalation Exposures Associated with Contamination Events in Water Distribution Systems. [PDF]

open access: yesPLoS ONE, 2016
When a water distribution system (WDS) is contaminated, short-term inhalation exposures to airborne contaminants could occur as the result of domestic water use. The most important domestic sources of such exposures are likely to be showering and the use

Inferring ancestral sequences in taxon-rich phylogenies [PDF]

open access: yes, 2010
Statistical consistency in phylogenetics has traditionally referred to the accuracy of estimating phylogenetic parameters for a fixed number of species as we increase the number of characters. However, as sequences are often of fixed length (e.g.

Natural Kinds in Evolution and Systematics: Metaphysical and Epistemological Considerations [PDF]

open access: yes, 2008
Despite the traditional focus on metaphysical issues in discussions of natural kinds in biology, epistemological considerations are at least as important.

Structure Formation in Butterfly Scales: Interplay of Genetic Control, Mechanical Instabilities, and Dynamic Material Properties

open access: yesAdvanced Functional Materials, EarlyView.
Butterfly wing scales are intricate cuticular functional nanosctructures. This perspective suggests that spatially varying material properties, cytoskeletal constraints, and growth‐driven mechanical instabilities shape the resulting nanoscale architectures created from single cells.

Microregion – A Regional Taxon Interposed between Commune and County [PDF]

open access: yesRomanian Review of Regional Studies, 2014
Unlike other countries belonging to the European Community, where the territorial grid was arranged in the matrix provided by the territorial units for statistics (NUTS) on five distinct hierarchical levels: macro-regions, regions, departments (districts)

Intraspecific classification of durum wheat: new botanical varieties and forms

open access: yesВавиловский журнал генетики и селекции, 2017
The Wheat Genetic Resources Department of VIR treats Triticum durum Desf. as a separate species. It contains 2 subspecies: subsp. durum and subsp. horanicum. Subsp. horanicum Vav. shows the highest spike density. Subsp.

Mass imbalances in EPANET water-quality simulations [PDF]

open access: yesDrinking Water Engineering and Science, 2018
EPANET is widely employed to simulate water quality in water distribution systems. However, in general, the time-driven simulation approach used to determine concentrations of water-quality constituents provides accurate results only for short water ...
