The variety of hair colours that we find among humans is due to mutations in some of our genes.

We could say that being human implies having a brain with human consciousness, but this definition has no discrete and precise boundaries.

Genetics and language are closely connected. Some genes in humans have been essential for the development of complex language.

Gattaca's message should be reconsidered as a defence of the possibility to create superior post-humans through genetic engineering.

Human enhancement through genome editing is one of the goals of transhumanism, but its implementation might generate important discriminations.

A few weeks back, we suffered a bot attack on Mètode's website which, fortunately, was swiftly resolved. As a precaution, we restricted access for a few hours. To access the site, visitors had to complete a visual captcha, a test where they have to click

The scientific community agrees that viruses are not alive. However, the idea sparks some debate because it depends on how we define life.

Humans, unlike some animals, do not base their mating choices exclusively on genetics. There are many cultural and social determinants.

Apart from the double helix, DNA can present other structures such as G-quadruplexes, whose study has boomed in recent years.

Thanks to advances in genetics, we can extract a lot of information from DNA and infer a fairly detailed portrait of the person it belongs to.
