Atlantic killifish are spared extinction in the face of pollution thanks to their remarkable genetic diversity.
In the past few decades scientists have found new and exciting ways to use DNA to answer scientific questions. There is now a new technique that could further revolutionize DNA analysis by using tiny pieces of tissue floating around in the ocean. Read more about how scientists are using this technique to answer questions about whale sharks.
Cancer is not normally thought of as an infectious disease, but researchers have discovered transmissible cancers in mussels and clams adding to a cadre of examples of contagious cancers.
Scientists have only recently started studying the wealth of biological diversity that is found on top of glaciers. Cryoconite holes hold microscopic communities of algae, bacteria, and viruses. These studies are revealing an increasingly complex web of interactions between community members, driving the evolution of many unique adaptations to survive in such stiff competition.
