Summary: Two well-preserved fossil lampreys from the Middle-Late Jurassic in North China provide insights into the feeding apparatus, life cycle, and biogeography of this group. These fossils have toothed feeding structures similar to modern lampreys, suggesting a predatory habit and a southern origin for living lampreys. The findings challenge the conventional understanding of the biogeographical pattern and suggest an earlier origin of lampreys in the Southern Hemisphere.

Summary: The development of a movable jaw is a significant evolutionary transition in animals. Jawed vertebrates rapidly diversified after appearing about 470 million years ago. Today, lampreys and hagfishes, representing the jawless grade, comprise less than 1% of living vertebrate species. The phylogenetic relationships within and between lampreys and hagfishes remain contentious, making their evolutionary history a major field of study.

Summary: This study examines the changes in functional diversity of tabulate coral assemblages over a 35 million year period and the impact of the late Devonian extinction event. The collapse of the huge Devonian reef systems resulted in the extinction of photosymbiotic tabulate coral taxa and had long-lasting consequences for reef building and shallow marine ecosystems in the Palaeozoic.

Summary: The olfactory system plays a crucial role in animal behavior, including feeding, mating, and evading predators. Studies on lampreys have identified neural pathways responsible for olfactomotor behavior, shedding light on the mechanisms underlying sensorimotor transformations. Modulation of bulbar neural activity by various inputs provides control over motor behavior in response to olfactory cues.

Summary: This study measured oral suction pressures and described suction dynamics of sea lamprey using pressure sensing panels. Suction pressures of adult sea lampreys did not differ significantly between static and flowing water, with suction dynamics distributed uniformly across their mouths.

Summary: Pelagic larval stages are widespread but it is unclear if they were present in the last common ancestor or evolved multiple times. To understand this, single-cell atlases were generated for larvae from two animal phyla. Clear similarities were found among ciliary band cells and apical organ neurons, suggesting a single origin of larvae within Spiralia. Clade-specific innovations were also found, including distinct myocytes and shell gland cells in the oyster larva.

Summary: Jawless vertebrates have an alternative adaptive immune system called VLRs, which recognize antigens through combinatorial assembly of LRR cassettes. Two types of VLRs, VLRD and VLRE, were found in lampreys, related to VLRA and VLRC. VLRD and VLRE are highly expressed in the triple-negative population of lymphocytes, and tissue distribution studies suggest they are T-like sublineages.

Summary: Brain tumours are a leading cause of death in children with solid tumours, and high-grade gliomas are particularly devastating. This study presents a clinically relevant in vivo model for paediatric glioma using zebrafish larvae and primary glioma stem cell cultures. The model allows for the monitoring of tumour invasion and evaluation of drug treatments. This research has the potential to improve understanding of cellular behaviour and personalized treatments for paediatric high-grade gliomas.

Summary: Cyclothems are distinctive repetitive stratal rhythms characteristic of the late Palaeozoic in the palaeotropical realm of Laurussia, recording repeated alternation of marine and nonmarine depositional conditions. They comprise arrays of terrigenous clastic, organic, and chemical/biochemical lithologies and are influenced by seasonal tropical climates and large-magnitude sea level fluctuations. Analysis of cyclothemic successions can contribute to a fuller understanding of sea-level excursions and palaeoclimatic changes during the late Palaeozoic.

Summary: A sustainable valorization platform for organic waste has yet to be fully developed. This study focuses on a new valorization route that converts food/agricultural waste to biodiesel using yellow mealworm larvae. The non-catalytic conversion process shows high tolerance against water and impurities, making it a promising method for biodiesel production.

Summary: This paper synthesizes information on the at-sea ecology of ten anadromous lampreys, categorizing them into four feeding modalities. Despite some direct evidence on feeding ecology, particularly for landlocked sea lampreys, there is still limited knowledge about the feeding ecology of most anadromous lamprey species.

Summary: The study focuses on the brain and cranial nerve preservation of a 319-million-year-old ray-finned fish, Coccocephalus wildi. The findings reveal a more complex pattern of brain evolution in ray-finned fishes than previously thought, providing insights into the deep evolutionary assembly of major anatomical systems. The research highlights the importance of ancient soft tissue preservation for understanding the evolution of anatomical structures beyond skeletal tissues.

Summary: During the Silurian and Devonian periods, cartilaginous fish developed specialized skeletal and dental features and improved their sensory systems. Fossils of a new species called Maghriboselache mohamezanei were discovered in Morocco, which shares key skeletal features with the iconic genus Cladoselache. Phylogenetic analysis reveals the evolutionary relationship between different shark families, indicating that the initial radiation of crown chondrichthyans occurred in the Late Devonian. The discovery of this new stem holocephalan provides insights into the sensory specialization and ecological diversity of early chondrichthyans.

Summary: Coombs Hill, a new fossil locality in the Witpoort Formation of South Africa, preserves a record of Famennian life in Gondwana, with diverse plant and shelly invertebrate fossils. The high-energy coastal marine setting and unique species composition at Coombs Hill provide important insights into the ecology of high-latitude environments during the Late Devonian period.ONGOING taxonomic analysis will provide a rare window into the ecology of high-latitude environments during this pivotal stage of Earth history, which immediately preceded the end-Devonian extinction.
