China shares fossil treasures with the world
The Anatomical Record, EarlyView.Abstract China has been a rich source of fossils for nearly a century, beginning with the discovery of so‐called Peking man (Sinanthropus pekinensis), known today as Homo erectus pekinensis in the mid 1920s. The first Chinese dinosaurs were described in 1929, the sauropod Helopus (now Euhelopus) and the ornithopod Tanius, described by the Swedish ...

5‐thiohistidine N‐acetyltransferase from Proteiniphilum saccharofermentans
ChemBioChem, Accepted Article.Ovothiol A is a 5‐thiohistidine derivative biosynthesized by a broad range of prokaryotic and eukaryotic organisms. Its redox‐active mercaptoimidazole side chain is believed to protect cells from oxidative stress. The three enzymes that produce ovothiol A from histidine, cysteine, and S‐adenosyl methionine have been identified and characterized.

The Depositional Record, EarlyView.The Bisperode section is one of the most expanded and complete sections with shallow‐marine Oxfordian strata in the LSB. This study provides a reference record for shallow‐marine settings and allows for the correlation of the strata from the LSB with Oxfordian deposits distributed elsewhere in the world.

Morphogenesis: a focus on marine invertebrates [PDF]
Marine Life Science & Technology, 2019 AbstractMorphogenesis is a process describing how the shapes of living tissues and bodies are created during development. Living and fossil organisms exhibit enormously diverse tissue architecture and body forms, although the functions of organs are evolutionally conserved.

Developmental Dynamics, EarlyView.Abstract Background Freshwater salinization is an emerging stressor in amphibian populations, and embryonic stages are most vulnerable. To better understand the variation in embryonic osmoregulation, we challenged embryos of two phylogenetically diverse anuran species, Xenopus laevis and Lithobates (Rana) sylvaticus, along a gradient of non‐lethal ...

Developmental Dynamics, EarlyView.Abstract Background The endocannabinoid system is a neuromodulatory system implicated in cellular processes during both development and regeneration. The Mexican axolotl, one of only a few vertebrates capable of central nervous system regeneration, was used to examine the role of the endocannabinoid system in the regeneration of the tail and spinal ...

Ecography, EarlyView.Temperature generally drives latitudinal patterns in the strength of trophic interactions, including consumption rates. However, local community and other environmental conditions might also affect consumption, disrupting latitudinal gradients, which results in complex large‐scale patterns.
