Are droneflies batesian mimics of honeybees?
… However, only dunnocks avoided both models and mimics but ate the other insects. More research is needed to fully establish the effectiveness of the mimicry. Finally, the effectiveness of the mimicry of a honeybee, social wasp and bumblebee by their hoverfly mimics was tested on humans using a …

Synthesis, spectroscopy, and electrochemistry of hydrogenase mimics
Hydrogenases (H2ases) provide microorganisms with hydrogen to be used as fuel for processes such a methanogenesis. The reversible hydrogen evolution reaction (HER) is catalyzed by anaerobic bacteria to expel hydrogen as a byproduct of photosynthesis. Hydrogen does not accumulate in our atmosphere …

Heterotrimeric coiled-coils as viral fusion protein mimics
The a-helical coiled-coil, formed by the association and supercoiling of two or more a-helices, is a ubiquitous protein structure that mediates a wide range of biological activity. It is characterized by a heptad repeat of amino acids that serve to form both the hydrophobic core and electrostatic …

Synthesis and characterisation of imprinted polymeric receptor mimics
Molecularly imprinted polymers (MIPs) are crosslinked polymers containing bespoke functionalised cavities arising from the inclusion of template molecules in the polymerisation mixture and their later extraction. When the polymers are prepared functional polymerisable monomers are included which …

DNA-based Artificial Mimics of Cell-surface Machinery
The plasma membrane of cells has evolved to mediate a broad array of functionalities critical to life, such as molecular trafficking, signal transduction, motility, adhesion and communication. These functionalities are often reliant on highly sophisticated membrane-anchored nano-machines, and …

UNDERWATER BONDING WITH POLYMER MIMICS OF MUSSEL ADHESIVE PROTEINS
When it comes to underwater adhesion, shellfish are the true experts. Mussels, barnacles, and oysters attach to rocks with apparent ease. Yet our man-made glues often fail miserably when trying to stick in wet environments. Results described herein focus on poly[(3,4-dihydroxystyrene)-co-styrene], …

Generating Gaseous Emboli Mimics in an ECMO Flow Phantom
… this project by mixing a translucent fluid that mimics the acoustic and rheological properties of blood. We explore various bubble generation designs and produce gaseous emboli mimics with diameters as small as 250 µm. In addition, we experimentally confirm a monotonic dependence between bubble …

Design and synthesis of substituted cyclopropanes as conformationally restrained dipeptide mimics
Molecular recognition plays a vital role in a wide variety of biochemical transformations. Of particular interest to chemists, biochemists, and biologists is the process by which enzymes recognize and bind substrates in the catalytic process. The relationship of peptide structure to properties and …
