Breathing in Plants and Chaos—Cosmic Tree Events in Cameroon and Beyond

open access: yesAnthropology of Consciousness, EarlyView.
ABSTRACT Contemporary practices of tapping into the wisdom of ancestral trees are described through three entangled recent events lived within the context of Bantu practices in Cameroon. In the three instances, the steered or chance encounters with high potency trees were serendipitous telling moments which brought something new to the horizon.

Towards an ‘absolute’ timing of biostratigraphic and environmental phases from the Saalian late glacial to the Weichselian pleniglacial in central Europe—Insights from a lacustrine succession in Lichtenberg, northern Germany

open access: yesBoreas, EarlyView.
Palynological records are central to the biostratigraphic subdivision of the Late Pleistocene in central Europe. Yet many interglacial and interstadial phases—such as the Eemian, Brörup and Odderade—remain only poorly constrained in time due to limited numerical dating.

Establishing Shape Correspondences: A Survey

open access: yesComputer Graphics Forum, EarlyView.
Abstract Shape correspondence between surfaces in 3D is a central problem in geometry processing, concerned with establishing meaningful relations between surfaces. While all correspondence problems share this goal, specific formulations can differ significantly: Downstream applications require certain properties that correspondences must satisfy ...

Behavioral Responses of Doryctobracon areolatus and Diachasmimorpha longicaudata (Hymenoptera: Braconidae) to Host Fruits Exploited by Heterospecific Competitors

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Female parasitoids can lower competitive costs by detecting rival‐species cues on shared host fruits (host habitats). We compared native Doryctobracon areolatus and introduced Diachasmimorpha longicaudata on guava fruits infested with Anastrepha fraterculus.

Do aphid endosymbiotic bacteria influence parasitoid searching behaviour through changes in aphid honeydew production?

open access: yesEcological Entomology, EarlyView.
Hamiltonella defensa infection increases honeydew production in certain aphid genotypes, potentially modifying aphid feeding behaviour. Parasitoid wasps, Aphidius ervi, are more attracted to honeydew from H. defensa‐infected aphids; though larger honeydew amounts may slightly deter searching.

Persistent in vitro nociceptor hyperexcitability and axonal retraction produced by repeated paclitaxel doses

open access: yesThe FEBS Journal, EarlyView.
Repeated paclitaxel exposure causes long‐lasting nociceptor hyperexcitability and axonal retraction in adult sensory neurons. Using a long‐term primary nociceptor culture, we show that hyperexcitability is mediated by sequential upregulation of NaV1.8, TRPV1, TRPA1, and TRPM8 channels.

Structural insights into xyloglucan recognition by an ABC transporter from a Gram‐positive, thermophilic bacterium

open access: yesThe FEBS Journal, EarlyView.
Athe_2052 is an ABC transporter substrate‐binding protein that recognizes xyloglucan heptasaccharide (XXXG), a soluble breakdown product of plant xyloglucan. The crystal structure of Athe_2052, together with binding assays and computational modeling, shows how XXXG is recognized by this sugar transporter.

Crystal structure and biochemical analysis of the polyester‐degrading carboxylesterase SM0281 from the symbiotic legume‐associated rhizobacterium Sinorhizobium (Ensifer) meliloti

open access: yesThe FEBS Journal, EarlyView.
The microbial degradation of synthetic polyesters such as polyethylene terephthalate (PET) is mediated by diverse α/β‐hydrolases, many of which remain poorly characterized. In this study, we investigated the α/β‐hydrolase SM0281 from Sinorhizobium meliloti and found that it exhibits robust carboxylesterase and polyesterase activities toward PET, PCL ...

Structural and functional insights into rhodopsin‐like and secretin‐like GPCR–arrestin interactions and regulation

open access: yesThe FEBS Journal, EarlyView.
Distinct GPCR phosphorylation barcodes and arrestin conformational states direct arrestin‐mediated signaling and trafficking. The graphical abstract depicts the structural diversity of GPCR–arrestin complexes by overlaying representative core‐engaged and tail‐engaged conformations.
