Changing dosing methods means fewer mice needed to study lung infections

Researchers will need fewer mice to study lung infections thanks to improvements in dosing methods, according to a new study from the University of California San Francisco (UCSF). Changing how animals are anesthetized and infected with microbes allows scientists to study lung infections using smaller group sizes and without having to use invasive dosing methods. The study is published in the American Journal of Physiology-Lung Cellular and Molecular Physiology.

Study finds decreasing physical activity in adolescence increases risk factors for cardiometabolic diseases

The health benefits of physical activity don’t concern just the older population. A study from University of Jyväskylä, UKK institute, and the network of Finnish Sports Medicine Centers examined what happens to physical activity in the transition to adulthood and how the changes in activity are associated with cardiometabolic risk factors. For the first time, longitudinal accelerometer data from Finnish adolescents were linked to health marker information collected in clinical examination.
