Out of sight: aggregations of epizoic comb jellies underneath mushroom corals [PDF]
Over two-thirds of all known species of comb jellies (Ctenophora) are planktonic, whereas the remainder (order Platyctenida) is composed of benthic species. Many of these are epizoic, some of which (Coeloplana spp.) are on octocorals (Matsumoto and Gowlett-Holmes 1996; Song and Hwang 2010), but none have been reported in association with scleractinians

Cteno‐Bot: An Untethered Metachronally Swimming Robot With Magnetoactive Propulsors
We present Cteno‐bot, an untethered ctenophore‐inspired robot which swims using metachronally coordinated appendages. A single mechanism controls up to 216 magnetoactive propulsors via a dynamically varying magnetic field. We show that the swimming speed of the robot can be increased without a corresponding increase in power requirement, simply by ...

Abstract Cells derived from the endocardium, epicardium, cardiac neural crest, and second heart field play a critical role in the formation of the valvuloseptal structures of the heart. Previous studies have shown that the expression of the transcription factor SOX9 in these cell populations is essential in the regulation of this process.

Abstract Soft robots, engineered from highly compliant materials, offer superior adaptability and safety in unstructured environments compared to their rigid counterparts. Recent advancements, fueled by bio‐inspiration and material programmability, have led to the rapid co‐evolution of their core modules: actuation, sensing, protection, energy, and ...

ABSTRACT The intensification of agricultural practices has led to an increase in the use of insecticides, raising concerns about the exposure of non‐target organisms, particularly pollinators. In this context, plant‐derived essential oils have been proposed as environmentally friendlier alternatives due to their low persistence; however, their ...

Functional morphology of the pharyngeal teeth of the ocean sunfish, Mola mola
Abstract Many fish use a set of pharyngeal jaws in their throat to aid in prey capture and processing, particularly of large or complex prey. In this study—combining dissection, CT scanning, histology, and performance testing—we demonstrate a novel use of pharyngeal teeth in the ocean sunfish (Mola mola), a species for which pharyngeal jaw anatomy had ...

Progress in Biodegradable Nonwoven Materials for Personal Protective Applications
ABSTRACT Personal protective equipment generates large waste streams, underscoring the need for materials that deliver protection without persistent environmental costs. This study reviews biodegradable nonwoven options and relates material choice and disposal routes to barrier performance, comfort, and footprint.

Genomic data do not support comb jellies as the sister group to all other animals [PDF]
Significance Clarifying the phylogeny of animals is fundamental to understanding their evolution. Traditionally, sponges have been considered the sister group of all other extant animals, but recent genomic studies have suggested comb jellies occupy that position instead.

Natural Biomaterials for Osteochondral Repair: From Source to Strategy
Biological origin‐guided overview of natural biomaterials and therapeutic strategies for osteochondral tissue engineering. The circular diagram categorizes representative materials and strategies into plant/algae‐derived, microbial‐derived, animal‐derived, and human‐derived sources, centered on an osteochondral defect repair model.

Finding a rare fossilized comb jelly reveals new gaps in the fossil record
They look like jellyfish but they aren’t. They seem inoffensive but are efficient predators — occasionally, they even eat fish. They are gelatinous and very delicate — and extremely rarely do they fossilize! Ctenophores, also known as comb jellies, are colourful, translucent animals, that drift through oceanic waters.
