Collective action: Occupied genetic switches hold clues to cells' history
If you wanted to draw your family tree, you could start by searching for people who share your surname. Cells, of course, don't have surnames, but scientists at the European Molecular Biology Laboratory (EMBL) ...

Chasing EHEC with the computer
Just a few genes make enterohaemorrhagic E. coli (EHEC) extremely dangerous to humans. If it were not for these genes, EHEC would hardly differ from harmless enteric bacteria. Bioinformatics scientists from t ...

A mystery solved: How genes are selectively silenced
Cells read only those genes which are needed at a given moment, while the others are chemically labeled and, thus, selectively turned off. Scientists at the German Cancer Research Center have now been the first to discover ...
