In rotaviruses, the selective packaging of eleven distinct genomic RNA segments requires virus-encoded protein NSP2 to alter the RNA structures, facilitating their interactions with each other.
The first reconstitution of an unconventional secretory mechanism uncovered the molecular mechanism by which Fibroblast Growth Factor 2 is secreted from mammalian cells.

Insight into the molecular assembly of a protein with a central role in infections paves the way to understanding how Rift Valley fever virus causes disease.
Glutamate receptor auxiliary proteins exert their effects on receptor gating through two divergent extracellular loops, explaining subunit specificity and allowing the construction of null versions that form complexes normally but do not modify receptor gating.

The tandem SH2 domains of Spt6 use novel mechanisms to bind unexpected phosphorylated serine and threonine residues in the RNA polymerase II linker to recruit Spt6 to sites of transcription and maintain repressive chromatin.
The range of footfall patterns seen in walking amphibians, reptiles and mammals, including hippopotamus, horse and (inverted) sloth, are consistent with simple principles of mechanical work minimization.
The placement of single methyl groups at certain positions in the sequence of small model transmembrane proteins consisting solely of leucines and isoleucines can modulate highly specific, productive interactions with the transmembrane domain of the erythropoietin receptor.
Isothermal titration calorimetry experiments clarify apparently discrepant results described previously and show that N-terminal sequences of complexin bind to SNARE complexes containing C-terminally truncated synaptobrevin when they include the syntaxin-1 juxtamembrane region.

Respiratory activity and inner membrane organisation of mitochondria from Drosophila melanogaster break down during ageing, but mouse heart mitochondria appear to be protected against age-related damage.
