Key Points

Under global warming, scientists have widely expected tropical cyclones (including typhoons and hurricanes) to bring more intense and frequent rainfall. The underlying physics seems intuitive: Rising temperatures allow the atmosphere to hold more moisture, which, combined with intensifying storms, should theoretically trigger more destructive downpours. However, when researchers analyze climate model projections, they encounter a puzzling phenomenon.

Temperature-tunable micropillars enable programmable sorting of particles and cells

A programmable microfluidic device developed at the Institute of Science Tokyo, Japan, combines deterministic lateral displacement, a microfluidic technique used to separate particles according to size, with temperature-responsive polymer micropillars to dynamically change separation conditions along a single channel. Using this device, researchers successfully separated multiple particle populations. Additionally, they efficiently isolated viable cancer cells, white blood cells and red...
