Similar genetic elements underlie vocal learning in mammals

The vocalizations of humans, bats, whales, seals and songbirds vastly differ from each other. Humans and birds, for example, are separated by some 300 million years of evolution. But scientists studying how these animals ...

A guide through the genome of crops

Plants show enormous variety in traits relevant to breeding, such as plant height, yield and resistance to pests. One of the greatest challenges in modern plant research is to identify the differences in genetic information ...

Understanding what drives cell typing

Scientists know that developing cells in a healthy embryo will transform into a variety of cell types that will make up the different organ systems in the human body, a process known as cell differentiation. But they don't ...

A model to decipher the complexity of gene regulation

How, where and when genes are expressed determine individual phenotypes. If gene expression is controlled by many regulatory elements, what, ultimately, controls them? And how does genetic variation affect them? The SysGenetiX ...

Wasp venom holds clues on how genes get new jobs

Amid the incredible diversity of living things on our planet, there is a common theme. Organisms need to acquire new genes, or change the functions of existing genes, in order to adapt and survive.
