Some three billion years ago, when life on this planet was still in its infancy, hot springs, geysers and volcanic hydrothermal vents were burgeoning with single-cell organisms. Temperatures hovered ...

A single gene that regulates testosterone levels in a 'crazy' species of shore bird controls the development of three wildly different types of males, a new study has found. Ruffs have long fascinated ...

A single gene in the shorebird species known as ruffs controls the blood concentrations of testosterone in males, and this in turn affects their appearances and behavior. Three adult male Ruffs ...

Microbial organisms adapted to extreme and inhospitable environments carry proteins within their proteome that significantly accelerate the dissolution of CO₂ in water, while also withstanding very ...

There are three morphs in ruffs that differ in their appearance and mating behavior. Males of the aggressive Independents (left) have more testosterone in their blood than the other two morphs (a male ...
