The Balloon Flight of the Spider

Moonsung Cho, Peter Neubauer, Christoph Fahrenson and Ingo Rechenberg's observational study of ‘ballooning’ flight by large Xysticus spiders reveals that they use 50 to 60 nanoscale silk fibers to catch light updraft currents in the atmospheric boundary layer.

The Expansion Threshold of a Species' Range

The intrinsic interplay between ecological and evolutionary dynamics explains formation of species’ range margins. This theoretical study by Jitka Polechová shows that adaptation fails when genetic drift reduces genetic diversity below that required for adaptation to a heterogeneous environment. Read the related Primer by Tim Connallon and Carla Sgrò.

Non-Canonical Initiation Factors for Translation Re-Initiation 

A combination of structural biology and functional assays, by Yasar Luqman Ahmed, Sibylle Schleich, Irmgard Sinning, Aurelio Teleman and co-workers, shows that two non-canonical initiation factors – DENR and MCTS1 – are required for re-initiation of translation after termination of an upstream open reading frame.

Unbinding NEMO: Treatment for Muscular Dystrophy

Jing Zhao, Paul Robbins and co-workers show that computationally identified inhibitors that dissociate IκB kinase complexes reduce acute inflammation and improve muscle pathology and strength in a mouse model of Duchenne muscular dystrophy.

Two TRPC Channels Turn the Worm's Head

Jihye Yeon, Jinmahn Kim, Kyuhyung Kim and colleagues show that head-steering locomotion of the nematode Caenorhabditis elegans is coordinated by the sensing of mechanical stretches by the proprioceptive SMDD neurons, using two TRPC channels, TRP-1 and TRP-2.

Feel the Fear... and Do It Anyway

The amygdala is known to control passive fear responses but does it also contribute to active behaviors? A study of monkeys performing a novel foraging task, by Kazutaka Maeda, Jun Kunimatsu & Okihide Hikosaka, suggests that amygdala neurons facilitate targeting saccades predictably based on aspects of emotional context, as is necessary for goal-directed and social behavior.

Zinc and Sperm Activation

Yanmei Zhao, Chieh-Hsiang Tan, Amber Krauchunas, Ronald Ellis, Kerry Kornfeld and co-workers show that the zinc transporter ZIPT-7.1 mediates the final, rapid stage in the development of sperm (“activation”) in the nematode Caenorhabditis elegans, suggesting that zinc signaling regulates this specialized cell differentiation event. Read the accompanying Primer by Diana Chu.

How Ants Switch Specialty

The switch from caring for the brood to caring for adult nestmates, in the ant Temnothorax longispinosus, is mediated by shifts in social cue responsiveness, in turn linked to activity of the Vitellogenin-like A gene.

essay

Songbird Syntax?

In language, the meaning of an expression depends on the meaning of its parts and the way they are arranged. This Essay proposes that claims of similar linguistic processing in songbird vocalizing are unfounded.
