Biologists have examined the complete genomes of viruses that infect the bacteria E. coli, P. aeruginosa and L. lactis and have found that many of these viral genomes exhibit codon bias, the tendency to preferentially encode a protein with a particular spelling.

 | Among humans, making yourself smell more alluring than you really are is a fairly harmless, socially accepted habit that maintains a complete perfume industry. However, it is a matter of life and death for caterpillars of large blue butterflies that dupe ant workers into believing them to be one of the ant's own larvae. ...> Full Article |
The full weight of a consortium of world-leading scientists - including those who helped decode the entire human genome - is being thrown at a parasitic worm less than 1mm long.

When ancient retroviruses slipped bits of their DNA into the primate genome millions of years ago, they successfully preserved their own genetic legacy. Today an estimated 8 percent of the human genetic code consists of endogenous retroviruses (ERVs)--the DNA remnants from these so-called 'selfish parasites.'

Animals, like plants, can build tolerance to infections at a genetic level, and these findings could provide a better understanding of the epidemiology and evolution of infectious disease, according to evolutionary biologists.

New insights into the evolutionary relationship between plant-dwelling insects and their parasites are revealed in the online open access journal BMC Biology. Researchers shed light on how sawflies evolved to escape their parasites and gain themselves an 'enemy-free space' for millions of years.

A new study explores the role of natural enemies, such as predators and parasites, for mixed mating, a reproductive strategy in which hermaphroditic plants and animals reproduce through both self- and cross-fertilization. The findings highlight the possible evolutionary consequences of these interactions.

Scientists from the Tasmanian Aquaculture and Fisheries Institute (TAFI) at the University of Tasmania have made an unexpected discovery that has rewritten 20 years of research. They have identified a new species of parasitic amoeba as the cause of a familiar problem troubling Atlantis salmon aquaculture in Tasmania.
