Genetics

In an important study for understanding how memories are made, EPFL scientists show that the flexibility of chromatin – packaged DNA inside the cell – plays a crucial role in “deciding” which neurons are involved in forming a specific memory.

EPFL researchers reveal a novel method to uncover bits of our genetic blueprint that come from ancient genetic parasites, offering fresh insights into human evolution and health.

Cell biologists at ETH Zurich describe a new organelle present in mammalian cells that is made of rings of DNA. This “mini-organ” could potentially play a role in autoimmune diseases, and it could help researchers to understand how cell nuclei evolved.

EPFL researchers uncover an intricate protein network controlling asymmetrical development of organs in the embryo, providing insights into genetic disorders and fundamental biology.

Researchers at ETH Zurich have developed a method that lets them genetically modify each cell differently in animals. This allows them to study in a single experiment what used to require many animal experiments. Using the new method, the researchers have discovered genes that are relevant for a severe rare genetic disorder.

The number of microbes that acquire antibiotic resistance depends on the time at which the antibiotic is added. This is a conclusion reached by a research group at Eawag on the basis of experiments with genetically modified bacteria that glow in different colours when they exchange genetic information with each other.
