Many natural populations are facing a “double threat” of reduced genetic diversity and new pathogen challenges. Therefore, understanding how hosts adapt to pathogens in small and fragmented populations has important ramifications for conservation, epidemiology and evolution.
Background. Nitrous oxide (N2O) is a potent greenhouse gas. Although atmospheric N2O levels are lower than that of CO2, it has a 300-fold greater global warming potential, and represents around 10% of total global greenhouse gas emissions.
The visualisation of three dimensional structures of molecules and the fluent translation between two dimensional representations and reality have long been recognised as challenges for the chemistry student.
Synthesis of new DNA binding compounds to target genetic diseases such as cancer and diabetes. It is often assumed that DNA exists only as the iconic Watson-Crick double helix but it can actually adopt many different types of structure depending on the sequence and environmental conditions.
