Multiple independent genetic code reassignments of the UAG stop codon in phyllopharyngean ciliates

Plos.org 

by Jamie McGowan, Thomas A. Richards, Neil Hall, David Swarbreck

The translation of nucleotide sequences into amino acid sequences, governed by the genetic code, is one of the most conserved features of molecular biology. The standard genetic code, which uses 61 sense codons to encode one of the 20 standard amino acids and 3 stop codons (UAA, UAG, and UGA) to terminate translation, is used by most extant organisms. The protistan phylum Ciliophora (the ’ciliates’) are the most prominent exception to this norm... Читать дальше...

Model supports asymmetric regulation across the intercellular junction for collective cell polarization

Plos.org 

by Katherine Levandosky, Calina Copos

Symmetry breaking, which is ubiquitous in biological cells, functionally enables directed cell movement and organized embryogenesis. Prior to movement, cells break symmetry to form a well-defined cell front and rear in a process called polarization. In developing and regenerating tissues, collective cell movement requires the coordination of the polarity of the migration machineries of neighboring cells. Though several works shed light on the molecular basis of polarity... Читать дальше...

In–silico simultaneous respiratory and circulatory measurement during voluntary breathing, exercise, and mental stress: A computational approach

Plos.org 

by Masami Iwamoto, Satoko Hirabayashi, Noritoshi Atsumi

Voluntary breathing (VB), short–term exercise (STE), and mental stress (MS) can modulate breathing rate (BR), heart rate (HR), and blood pressure (BP), thereby affecting human physical and mental state. While existing experimental studies have explored the relationship between VB, STE, or MS and BR, HR, and BP changes, their findings remain fragmented due to individual differences and challenges in simultaneous, BR, HR, and BP measurements.

Randomness as a driver of inactivity in social groups

Plos.org 

by Abel Bernadou, Raphaël Jeanson

Social insects, such as ants and bees, are known for their highly efficient and structured colonies. Division of labour, in which each member of the colony has a specific role, is considered to be one major driver of their ecological success. However, empirical evidence has accumulated showing that many workers, sometimes more than half, remain idle in insect societies. Several hypotheses have been put forward to explain these patterns, but none provides a consensual explanation. Читать дальше...

Comprehensive analysis of the C. elegans connectome reveals novel circuits and functions of previously unstudied neurons

Plos.org 

by Scott W. Emmons

Despite decades of research on the Caenorhabditis elegans nervous system based on an anatomical description of synaptic connectivity, the circuits underlying behavior remain incompletely described and the functions of many neurons are still unknown. Updated and more complete chemical and gap junction connectomes of both adult sexes covering the entire animal including the muscle end organ have become available recently. Here, these are analyzed to gain insight into the... Читать дальше...
