Particles in air help fatten clouds’ water droplets
Making their own clouds has shown scientists how the fattest water droplets form. Understanding this could lead to better forecasts of climate change.

This umbrella ‘listens’ to rain — for science
Scientists have developed an umbrella that ‘listens’ to falling raindrops. One day, a fleet of such simple rain gauges may help scientists better map weather patterns and changes in Earth’s water supplies.
