Cause of oversized placentas in cloning found after two decades

One reason a technique for cloning animals often results in oversized placentas, and hence failed births, has been uncovered in mice by an all-RIKEN team. This finding will help improve the success rate of the cloning method ...

Study shows that father's age can affect offspring lifespan

How does the father's age at conception affect his children? Researchers at the German Center for Neurodegenerative Disease (DZNE) and fellow scientists have studied this question in mice. Their findings, which have been ...

Chromosome organization emerges from 1-D patterns

An epigenetic key to unlock behavior change

When it comes to behaviour, researchers have moved beyond the "nature versus nurture" debate. It's understood that genes and environment both play a role. However, how they interact at a molecular level to shape behaviour ...

Discovering a new mechanism of epigenetic inheritance

Giacomo Cavalli's team at the Institute of Human Genetics (University of Montpellier / CNRS), in collaboration with the French National Institute for Agricultural Research (INRA), has demonstrated the existence of transgenerational ...
