Plant-emitted volatile organic compounds (VOCs) play fundamental roles in atmospheric chemistry and ecological processes by contributing to aerosol formation1 and mediating species interactions2. Rising temperatures and the associated shifts in vegetation composition have been shown to be the primary drivers of plant VOC emissions in Arctic ecosystems3. Although herbivorous insects also strongly a

YjbH is a bacterial adaptor protein required for efficient proteolysis of the RNA polymerase-binding transcription factor Spx by the ClpXP protease. We report the structure of YjbH in complex with Spx. YjbH comprises a DsbA-like thioredoxin domain connected via a linker to a C-terminal domain reminiscent of the winged helix-turn-helix fold. The interaction between YjbH and Spx involves a large sur

Pit vipers detect moving warm-blooded prey with infrared receptors in their pit organs. Neurons in two brain nuclei extract the direction of prey motion by lateral inhibition circuits similar to those known from visual systems.

Purpose of the article: Autism spectrum disorder (ASD)is an impairing neurodevelopmental disorder with an unknown etiology. The present study aims to investigate if the auditory brainstem response (ABR)to complex stimuli in children and adolescents diagnosed with ASD can be a possible objective biomarker in autism. Materials and methods: The ABR of 39 youth with ASD (7–18 years)were compared to th

Nodularia spumigena is a toxic cyanobacteria that blooms in the Baltic Sea every year. In the brackish water of the Baltic Sea, its toxin, nodularin, mainly affects the biota in the surface water due to the natural buoyancy of this species. However, the fate of the toxin is unknown, once the cyanobacteria bloom enters the more saline waters of the Kattegat. In order to investigate this knowledge g

The strawberry tortrix (Acleris comariana Lienig and Zeller) (Lepidoptera: Tortricidae), is a major pest of strawberry in Denmark and southern Sweden. Chemical and electrophysiological analyses revealed a single compound, (E)-11,13-tetradecadienal (E11,13-14:Ald), in gland extracts of females eliciting a strong antennal response in conspecific males. Also (Z)-11,13-tetradecadienal (Z11,13-14:Ald)

Cruises are one of the fastest growing and most energy-intense tourism segments, accounting for significant emissions of greenhouse gases, as well as air pollutants such as nitrous oxide (NOx) and particulate matter (PM2.5). International measures to limit the sector's environmental impacts have so far had no significant effects. This highlights the importance of national, regional or port-specifi
