    Viruses Overheard Talking to One Another

    For the first time, viruses have been found to communicate with one another, leaving short “posts” for kin and descendants. The messages help the viruses reading them to decide how to proceed with the process of infection.

    New Stem Cells Go Back Further

    One challenge in using induced pluripotent stem cells (iPSCs) – which are ""reprogrammed"" regular cells – is that they retain traces of their former identity (e.g., skin cells). Dr. Jacob Hanna has now created iPSCs that are completely reset to the earliest possible state. This could lead to applications such as custom-grown transplant organs.
