CYTOPLASMIC INCOMPATIBILITY: WHY IS IT SEXUALLY ASYMMETRIC?

Why Antagonistic Traits against Cytoplasmic Incompatibility Are So Elusive

Intracellular symbionts are present in a wide variety of animals, plants and other life forms (Correa and Ballard, 2016); and have an intriguing lifestyle. To enhance their spread, intracellular symbionts have evolved a variety of mechanisms. Some of them provide benefits to their host and are effectively mutualists (e.g., Buchnera in aphids; Douglas, 1998), while others bias the sex ratio of t...

Cytoplasmic incompatibility in social insects

In this essay, I briefly summarise reproductive phenotypes associated withWolbachia in insects, present a model of the dynamics of infection frequency for maternally-inherited microorganisms and determine the effect of changing costs associated with incompatibility, infection-related fecundity loss and number of mates in ideal populations of social insects. The model predicts that infections of...

Rheumatoid cachexia: what is it and why is it important?

Radiogenomics: what it is and why it is important.

In recent years, a new direction in cancer research has emerged that focuses on the relationship between imaging phenotypes and genomics. This direction is referred to as radiogenomics or imaging genomics. The question that subsequently arises is: What is the practical significance of elucidating this relationship in improving cancer patient outcomes. In this article, I address this question. A...

Annotating scientific data : why it is important and why it is difficult

Annotation of existing data is becoming a standard tool in many branches of e-science. Increasingly, databases are being built to receive annotation, and other tools are being developed to annotate existing databases. Annotation is becoming an important part of communication among scientists. In this paper we review various kinds of annotation systems and describe the importance of designing da...
