Is sex primarily a strategy against transmissible cancer?

One of the greatest enigmas of evolutionary biology is that while sex is the dominant mode of reproduction among multicellular organisms, asexual reproduction appears much more efficient and less costly. However, in a study ...

Male fish can thank genes for colourful looks

Striking traits seen only in males of some species – such as colourful peacock feathers or butterfly wings – are partly explained by gene behaviour, research suggests.

Fluconazole makes fungi sexually active

The yeast Candida albicans occurs in most healthy people as a harmless colonizer in the digestive tract. However, it can also cause life-threatening infections, especially in immunocompromised patients.

Reproductive strategy drives slower female aging

The aging of males and females is influenced by how they choose to invest their available energy, according to a study of fruit flies carried out at Linköping University, Sweden. The results, published in The American Naturalist, ...

The mechanisms of genetic diversification in Candida albicans

Candida albicans is one of the most formidable fungal species infecting humans. Investigating the structure and reproduction methods of pathogenic populations can reveal how they emerge and spread. A team of scientists has ...

Fish study finds genes that regulate social behaviors

Genes in an area of the brain that is relatively similar in fish, humans and all vertebrates appear to regulate how organisms coordinate and shift their behaviors, according to a new Cornell University study.

Genes don't always dictate that 'boys will be boys'

As an evolutionary biologist focusing on animal behaviour, I'm sometimes asked what relevance our research has for human behaviour. Years ago, I would duck the question because it was such a passionately polarising, political ...
