ACE-M-2 (Advanced Colloids Experiment-Microscopy-2): Sometimes it’s hard to tell a gas from a liquid. Advanced Colloids Experiment-Microscopy-2 (ACE-M-2) observes the microscopic behavior of liquids and gases separating from each other. The investigation examines the behavior of model (colloid rich) liquids and model (colloid poor) gases near the critical point, or the point at which there is no distinct boundary between the two phases. ACE-M-2 uses a new microscope to record micro-scale events on short time scales, while previous experiments observed...

The recent massive wildfires in Australia have killed more than 30 people and an estimated 1 billion animals, and burned 2,500 homes and millions of acres. And the human toll is expected to rise even after the blazes wind down. According to Harvard scientist Loretta Mickley, senior research fellow in atmospheric chemistry at the Harvard John A. Paulson School of Engineering (SEAS), long-term exposure to the smoke-filled air hanging over much of the country could lead to many premature deaths in Australia. In 2015, Mickley and a...
