    Researchers aren't the only ones who concern themselves with animal welfare in the lab. Vets are asked regularly to monitor and care for these animals — a role that can call for some difficult decisions. Kerri Smith talks to Sarah Wolfensohn, head of veterinary services at the University of Oxford, UK, about the challenges and conflicts presented by caring for experimental animals.

    Obesity and Diabetes

    The incidence of obesity and type 2 diabetes are increasing rapidly, threatening health worldwide. The prevalence of metabolic syndrome, an obesity-related condition and risk factor for type 2 diabetes and cardiovascular disease, is also increasing. Greater understanding of the processes involved in these disorders is therefore urgently required, as are new treatment options.
