The discovery of the CRISPR-Cas9 system of genome editing was the result of an explosive encounter between two different programs of research. One was the study of an ensemble of genomic sequences (CRISPR) present in eubacteria and archaea, the functions of which were totally ignored. The firs...
demonstrated that the CRISPR-Cas system provides acquired immunity against bacteriophages: infection leads to the formation in a polarized way of new spacer sequences and to protection against further infection, which is abolished by the deletion of the spacer sequences or of some of the Cas genes...
Horizontal gene transfer (HGT) is defined as the intragenerational sharing of genetic material. HGT represents one of the most important evolutionary forces in bacteria as it enables rapid adaptation to changing environmental pressures through the acquisition of new traits such as virulence, metabolic pa...
However, there has not been a consistent and standard definition of cell types, although it is critical for reproducible investigation. It is often unclear if cell types defined by different phenotypic features agree with each other nor which feature is the right one to define cell types. ...

Hello and welcome to the seventh season ofFlash Forward! We’re back! I’m Rose and I’m your host. Flash Forward is a show about the future. Every episode we take on a specific possible, or not-so-possible, future scenario. We always start with a little field trip to the future ...
COMING FEB 2020 My first post of 2018 addresses an idea that’s just starting to gain traction – one you’ll hear a lot more about from me soon: Quality 4.0. It’s not a fad or trend, but a reminder that the business environment is changing, and that p
