A Physical Analysis of Magnetotactic Bacteria: Nature’s Microscopic Compass as a Solution to a Motile Biotope

Figure 1: Magnetotactic Bacteria (Perduca, 2016). Magnetotactic bacteria (MTB) are unique aquatic microaerophiles that can align and move in the direction of the Earth’s magnetic field. In this paper, the basic physical properties of magnetosomes, some mechanisms, such as magnetotaxis, and phototaxis, involved in the MTB’s motion, and the role…

Frustules: Design solutions in Diatoms

There are many microorganisms in the universe, and they can generally be sorted into three types: prokaryotic, eukaryotic, and acellular. The subject of this paper is a member of the eukaryotic family, and they are commonly present in nature: the diatom. The diatomite which is formed by the death of…

Superpowers in the Animal Kingdom

Navigating an unfamiliar environment can prove difficult for organisms that lack the necessary adaptations. Nevertheless, some animals possess unique senses that help them with the perception of their specific surroundings. Over many years of evolution, they have adopted ‘superpowers,’ ranging beyond our five senses. These abilities aid their species in…

Masters of Camouflage: Mechanisms of Dynamic Skin Colouration in Cephalopods

Within the animal kingdom, predation pressure has been one of the largest contributing factors towards evolution within species. The presence of predators within communities has forced animals to develop both passive and defensive mechanisms in order to increase fitness. For this research paper, the focus will be directed towards the…

Courtship and Mating: the Physics of Sexual Dimorphism and its Evolutionary Function

Sexual dimorphisms are defined as the differences in size and anatomy between sexes of animals of the same species. These differences arise from reproductive pressures and oftentimes have no survival benefits. The manifestation of such sexual dimorphisms varies significantly based on courting and mating practices. In this essay, we analyze…
