Slowed cell division causes microcephaly
Slowed cell division causes microcephaly
Scientists from the University of Geneva demonstrate how the mutation of a single gene can slow down cell division and lead to an abnormally small brain. The birth of a human being requires billions of cell divisions to go from a fertilised egg to a baby. At each of these divisions, the genetic material of the mother cell duplicates itself to be equally distributed between the two new cells.

Researchers identify how to prevent cancer metastases
Metastases can develop in the body even years after apparently successful cancer treatment. They originate from cancer cells that migrated from the original tumor to other organs, and which can lie there inactive for a considerable time. Researchers have now discovered how these "sleeping cells" are kept dormant and how they wake up and form fatal metastases.
