A 3D map of the ovary suggests that the organ “counts” its oocytes

A CRG study has reconstructed mouse ovaries in 3D and suggests that the organ adjusts the proportion of oocytes that become activated throughout life.

Diving into genetic mutations

Marc de Manuel (IBE) and Donate Weghorn (CRG) reunite to dive into the world of genetics and mutations and to discuss careers in research in the third episode of ‘Science With A View’ season two.

The journey of steroid hormones

In this outreach article, we discuss the journey of hormones like testosterone as they reach the DNA and modify gene expression.

The map of the switches that control our genes

The ENCODE consortium, with participation from the CRG, has created the most comprehensive atlas to date of the DNA regions that regulate gene activity.
