Engineered Living Systems With Self‐Organizing Neural Networks: From Anatomy to Behavior and Gene Expression

Advanced Science, Volume 13, Issue 28, 18 May 2026.
Ectodermal tissue excised from Xenopus embryos self‐organizes into a three‐dimensional mucociliary organoid. Here, we generate a neural variant, termed neurobot, by implanting neural precursor cells. Neurobots develop mature neurons, adopt distinct morphologies, exhibit more complex motility, and respond differentially to neuroactive compounds. Imaging

Development of the Pectoral Lobed Fin in the Australian Lungfish Neoceratodus forsteri

Frontiers in Ecology and Evolution, 2021
The evolutionary transition from paired fins to limbs involved the establishment of a set of limb muscles as an evolutionary novelty. In parallel, there was a change in the topography of the spinal nerves innervating appendicular muscles, so that ...

Ethmosphenoid endocasts elucidate evolutionary brain divergences and interrelationships of stem tetrapods (Sarcopterygii, Tetrapodomorpha)

Papers in Palaeontology, Volume 12, Issue 3, May/June 2026.
Abstract Nearly half of all living vertebrate diversity can be traced back to a single lineage of lobe‐finned fishes (piscine sarcopterygians) that radiated during the Palaeozoic Era. In recent years, the phylogenetic framework of tetrapodomorph fishes has largely stabilized, with the exception of the ‘Osteolepiformes’, the interrelationships of which ...

Structural and functional divergence of growth hormone-releasing hormone receptors in early sarcopterygians: lungfish and Xenopus. [PDF]

PLoS ONE, 2013
The evolutionary trajectories of growth hormone-releasing hormone (GHRH) receptor remain enigmatic since the discovery of physiologically functional GHRH-GHRH receptor (GHRHR) in non-mammalian vertebrates in 2007.

Uncovering a 500 million year old history and evidence of pseudogenization for TLR15

Frontiers in Immunology, 2022
IntroductionToll like receptors (TLRs) are at the front line of pathogen recognition and host immune response. Many TLR genes have been described to date with some being found across metazoans while others are restricted to specific lineages.

Oldest Cretaceous latimeriid elucidates cranial evolution in derived and extant coelacanths (Actinistia, Latimeriidae)

Papers in Palaeontology, Volume 12, Issue 2, March/April 2026.
Abstract The fossil record of coelacanths (Actinistia) is diminished by several nominal gaps that obscure vital information pertaining to the clade's evolutionary history. Latimeriidae, the family that includes the extant coelacanth Latimeria, in addition to the Cenozoic, has an outstanding missing gap of 50 myr during the Mesozoic, with no records of ...
