In AIP Advances, researchers simulate different evacuation scenarios in case of a dual-engine fire in an Airbus A320. They compare three different cabin layouts with three different ratios of passengers over the age of 60 and three different distributions of those passengers, finding that the proportion and location of elderly passengers have the largest effect on evacuation time. The fastest option — with 30 elderly passengers evenly distributed throughout the cabin — still required 141 seconds for all passengers to reach the ground.

A new study shows that systems designed to capture methane from cow manure, called dairy digesters, are highly effective. But on the rare occasions they fail, the leaks are large enough to offset their climate benefits.

Researchers at The University of Manchester have created a groundbreaking physics‑informed machine‑learning model that can run molecular simulations for unprecedented lengths of time, even at temperatures as high as 1000 Kelvin.
