(Phys.org) —A team of Canadian and Singaporean researchers has discovered that remnants of ancient viral DNA in human DNA must be present for pluripotency to occur in human stem cells. In their paper published in the journal ...
MIT researchers have shown that they can turn genes on or off inside yeast and human cells by controlling when DNA is copied into messenger RNA—an advance that could allow scientists to better understand the function of ...

(PhysOrg.com) -- A study of the genetic structure of viruses in an Antarctic lake has revealed an astonishing genetic richness in the large number of viral families discovered.
An international team of scientists led by geneticists and disease biologists from the University of Oxford and LMU Munich have used ancient DNA to trace the evolution of Marek's Disease Virus (MDV). This global pathogen ...
