The largest genetic study of tuberculosis (TB) susceptibility to date has led to a potentially important new insight into how the pathogen manages to evade the immune system. Published today in the journal Nature Genetics, the study advances understanding of the biological mechanisms involved in TB, which may open up new avenues to design efficient vaccines for its prevention.

Human genome includes 'foreign' genes not from our ancestors

12 March 2015

Many animals, including humans, acquired essential ‘foreign’ genes from microorganisms co-habiting their environment in ancient times, according to research published in the open access journal Genome Biology. The study challenges the conventional view that animal evolution relies solely on genes passed down through ancestral lines and suggests that, at least in some lineages, the process is still ongoing.

Families with a difference: the reality behind the hype

12 March 2015

Families come in many guises. Some parents are same-sex; others are single by choice. Growing numbers of children are conceived through assistive reproductive technology. What do these developments mean for the parents and children involved? Professor Susan Golombok’s book, Modern Families, examines ‘new family forms’ within a context of four decades of empirical research.
