Amorous Planthoppers Twerk to Woo

Leonidas-Romanos Davranoglou, Alice Cicirello, Graham Taylor and Beth Mortimer show that planthopper insects produce fast abdominal twerks for vibrational communication through the substrate, employing a novel vibratory organ that uses two reciprocal elastic recoil mechanisms to generate fast cyclical motion.

Hotspots of Human Impact

A global analysis of human impacts on threatened vertebrates, by James Allan, Oscar Venter and co-authors, shows that they are almost ubiquitous across Earth, and hundreds of species have no refuge from these impacts. The study also identifies hotspots of impacted species richness and coolspots of unimpacted species richness.

Induced Same-Sex Mating in Candida 

Sexual reproduction is critical for the evolution of pathogenesis and antifungal resistance in pathogenic fungi; Guobo Guan, Li Tao, Guanghua Huang and co-workers show that the predominantly clonal pathogen Candida albicans undergoes efficient same-sex mating under stressful environments, and that the Hsf1/Hsp90 signaling pathway functions as a major regulator in this process.

Regulating Oxidative Stress–Induced Energy Consumption

A study of the response of fruit flies to oxidative stress, by Human Riahi, Jamie Kramer, Annette Schenck and colleagues, highlights the importance of energy metabolism in fuelling the coordinated transcriptional response to oxidative stress, and identifies the histone methyltransferase G9a as a key player in these processes.

Two-Speed Growth of Human Cells

Single-cell time-lapse imaging and transcriptomic analysis, by Mingwei Min and Sabrina Spencer, reveal why some human cells proliferate more slowly than the majority of the population, with cellular stress responses triggering entry into a slow-cycling state to promote cellular survival in unpredictable environments.

Resolving Perceptual Ambiguity

Electroencephalography, intracranial recording, and fMRI measurements of the human brain, by Lu Shen, Biao Han, Lihan Chen and Qi Chen, reveal how perceptual inference employs intrinsic brain activity to bias the perception of ambiguous sensory information towards predicted percepts.

Regulating the (T) Regulators

Marcin Łyszkiewicz, Samantha Winter, Natalia Ziętara, Andreas Krueger and co-workers show that expression of microRNA miR-181a/b-1 in the thymus controls the generation of regulatory T cells and imposes a developmental legacy on the effector function of peripheral regulatory T-cells.

Seasonality of Wikipedia Searches

Analysis of more than two billion page views over three years for Wikipedia articles for 31,751 species across 245 languages reveals that many species show a seasonal pattern, and several online variations mirror real-world phenology.

The Origins of Beer Yeasts

Brewer's yeast has been used to make fermented beverages for millennia. A genome analysis of beer and other yeast strains shows that beer yeast have a polyploid admixed origin derived from European and Asian wine populations.

Rods Phase-Shift the Retinal Clock

Rod photoreceptors in the retina play a major role in the phase-shifting response of the mammalian retinal clock to high levels of light, while melanopsin and mid-wavelength cones influence the intrinsic period of the clock.
