Lung Imaging Research Gets Its Second Wind
Bytes versus breathsSeptember 2012
Results: Computational fluid dynamics (CFD) provides a quantitative basis for predicting the pulmonary airflow patterns that carry inhaled materials inside the body. This is not only potentially useful for establishing safer exposure limits to airborne pollutants but also for improving targeted drug delivery in patients with pulmonary disease. One prerequisite is that simulated predictions be thoroughly tested in a living organism, where respiratory airflows depend not only on airway shape and curvature but also on local lung mechanics and associated differences between health and disease.
Dust Achieves Lofty Aspirations
Disposition to form ice crystals is measured and modeled for a new-fangled frameworkSeptember 2012
Results: Instead of dust-bunnies under the sofa, this dust helps form ice crystals that are at the heart of clouds. Researchers at Pacific Northwest National Laboratory used dust’s loftier disposition to create a new way to calculate how all particles, not just dust, attract and form ice crystals in clouds. Steering multiple data points into one flexible calculation, they efficiently simulated how ice forms on dust particles, a calculation that will help them nail down how ice latches on to atmospheric soot, organic, and biological particles as well. Their research was published in the August issue of Atmospheric Chemistry and Physics.
