Summary: In this paper, a physics-based model of suction phenomenon is proposed for simulating deformable objects like suction cups. The model utilizes a constraint-based formulation to simulate pressure variations within suction cups, represented as pressure constraints coupled with anti-interpenetration and friction constraints. The method is capable of detecting multiple air cavities using collision detection information. The pressure constraints are solved based on the ideal gas law, considering various cavity states. The model is tested in different scenarios, demonstrating its potential applications in soft robotics and computer animation.

Summary: This study investigated the morphologies of papilla and unculi in 67 species of loricariid fish, and found four types of papilla and eight types of unculi. Hypotheses about the interaction mechanisms between oral disc structures and natural substrates were proposed based on the material properties and shape of these structures.

Summary: The novel magnetic adhesion achieved by the actuation of Ecoflex embedded with iron particles can switch the adhesion state quickly and is safe for humans in terms of driving voltage. By optimizing the design using a mechanical model and varying the adhesive force with different magnetic fields, complex waveforms can be achieved. This magnetic adhesion technology demonstrated in the article shows promising applications for transfer printing and intelligent sensing where accurate and rapid control is needed.

Summary: Materials can experience creep and time evolution even without plasticity, diffusion, or viscoelasticity. This creep is caused by the formation of adhesive chemical bonds, resulting in an increase in contact area and shear strength, and affecting the aging process of frictional contacts.

Summary: In this study, genes required for Caulobacter crescentus to activate surface attachment in response to signals from flagellum were identified. The genes involved in transmitting information from the flagellum are grouped into two pathways, one controlling the bacterium's morphogenesis program and the other required for flagellar motility. The results support a model where a developmental and a mechanical signaling pathway operate in parallel downstream of the flagellum and converge to regulate adhesion.

Summary: This study investigated the impact of enzymatic quorum quenching (QQ) on the adhesion strength of biofilms, finding that QQ enzymes could significantly reduce adhesion strength and negatively affect biofilm accumulation rates. Additionally, QQ was found to alter the properties of biofilms by degrading signal molecules, suggesting a potential new strategy for managing biofilm adhesion in bioreactors.

Summary: Marine biofilms frequently and spontaneously form on almost any submerged solid surface in seawater. This study investigated the composition and predicted functional potential of bacterial communities in surface biofilms and confirmed Vibrio gigantis as an early and abundant colonizer, functionally linked to genes associated with cell motility, surface attachment, and quorum sensing. The study also monitored the adhesion dynamics of V. gigantis on a solid surface and found a convincing tendency of spontaneous adhering.

Summary: The emergence of drug-resistant bacterial strains is increasing due to the presence of biofilms that protect bacteria from antimicrobial agents. This study introduced biological silver nanoparticles as an anti-biofilm agent against multidrug-resistant E. coli U12 on urinary catheters. The silver nanoparticles showed excellent biocompatibility and significant antibacterial activity against E. coli U12, reducing adhesion and causing cell rupture.

Summary: This study presents a sucker device inspired by abalone, which can adhere to three-dimensional surfaces using both suction and adhesion mechanisms in dry and liquid environments. The switching between soft/hard contact states leads to a change of adhesive strength over 30 times. Compared to conventional suckers or friction-based grippers, this device has wider potential applications.

Summary: The study reveals that the peeling behavior of viscoelastic tape is influenced by either perfect adhesion or frictional sliding conditions, with the latter being more dependent on the peeling velocity. Low-angle peeling results in a tougher peeling behavior compared to traditional stuck cases, in line with the locomotion control mechanisms of certain biological systems.

Summary: Morphometrics of fish otoliths are commonly used to study population structures and environmental impacts on development. Automating the measurement process can save valuable time and resources, while providing more accurate information compared to manual 2D methods. The study found that automated 3D methods were able to detect differences that 2D methods could not, and were significantly faster in processing time.

Summary: This study investigates the bioconstruction and bioerosion processes in the northern Adriatic coralligenous reefs using limestone tiles deployed in different benthic assemblages. The main builders were encrusting calcareous rhodophytes, bryozoans, and barnacles, while the most effective borers were sponges and bivalves. Bioconstruction was found to surpass bioerosion in 3 years, and after 12 years, the net balance was essentially nil at all sites.

Summary: Elasmobranch fishes, including the spotted ratfish, have adapted their jaw morphology and mechanical properties to consume both hard and soft prey. The fusion of the upper jaw with the cranium reduces deformation, while the lower jaw is designed to resist bending and occludes with the wider and flatter region of the upper jaw, suggesting a function for crushing or cracking prey.

Summary: The northern clingfish, Pacific spiny lumpsucker, and marbled snailfish are fishes that have evolved ventral adhesive discs. Adhesive performance is influenced by the flow regimes in their habitats. The northern clingfish has the highest adhesive forces, while lumpsuckers and snailfish generate less adhesive force but have different body shapes and habitat preferences.

Summary: Recent studies have shown that balaenids likely feed using a self-cleaning, cross-flow filtration mechanism, while how filtering is achieved in rorquals remains unclear. This study used a multimodal approach to investigate baleen anatomy in five species of rorqual whales and found that larger whales exhibited hypoallometry relative to body length. The study also proposed a model for estimating the effective pore size, which may reflect changes in resistance through the filter that affect fluid flow rather than prey size.

Summary: This study used 3D geometric morphometrics and phylogenetic analysis to study the skull evolution of ghost electric knifefishes. The results showed the presence of clades characterized by morphological stasis or phylogenetic conservatism in the apteronotid species. Additionally, certain phenotypic combinations were found to dominate among species and clades. These findings provide evidence for developmental or functional constraints in the evolution of craniofacial phenotypes in this ecologically dominant clade.
