We know pathogens from other species can endanger us. Scientists are better equipped than ever to do something about it, but political buy-in is crucial.
A few rare viruses can reach the fetus when pregnant women are infected, with tragic result. As explored in this Q&A, researchers are figuring out how the placenta acts as protector and how some pathogens slip through.
The field has long been more mice than men. New technologies and systems-based approaches with human cells may soon fill gaps in our understanding of autoimmune disease and health, Mark Davis says in a Q&A.
Sure they cause disease, but the microbes can be a help as well. Witness long-lasting pepper seeds, drought-resistant crop plants and even our own placentas.
Genetic advances may make it possible to grow transplantable tissues in other species. That could solve immunity and availability issues, but raises ethical concerns.
