This week in Science, Michael K. Rosen and 10 other members of a large collaboration at the Marine Biological Laboratory, the Chromatin Consortium, propose a long-awaited model for how the properties of a condensate can emerge from the properties of the individual molecules that compose it.

Using sound measurements from NASA’s Mars missions to the best extent possible requires an accurate understanding of how sound propagates on the red planet. Focusing on the Jezero crater, the 2021 landing and exploration site of NASA’s Perseverance rover and its attached Ingenuity helicopter, Charlie Zheng and Hayden Baird have simulated how sound moves through and scatters off the region’s complex terrains, whether it comes from a moving or stationary source. They hope their model will help identify signals and patterns that indicate specific Martian atmospheric events.

After collecting and analyzing data for a decade, a group of scientists, including a team from Rutgers, have debunked a decades-old theory about a mysterious particle.
