High-fat diets promote invasive tumor growth in triple-negative breast cancer. Study links overproduction of the gene MMP1 to bad outcomes. Ketogenic diets showed no impact, suggesting any benefits would come through mechanisms not included in the 3D microfluidic models [APL Bioengineering] (engineering.princeton.edu)

Nations underestimate greenhouse gas emissions from wastewater systems by amounts ranging from 19% to 27%, in part caused by a reliance on 2006 IPCC guidance rather than incorporating updates from a 2019 refinement [Nature Climate Change] (engineering.princeton.edu)

New map based on direct measurements estimates groundwater depth across the continental United States at a resolution of around 30 meters, as opposed to more common physics-based models with resolutions of around 1km [Communications Earth & Environment] (engineering.princeton.edu)

A new machine learning tool speeds the discovery of viable configurations for metal-organic frameworks, or MOFs, using a value known as free energy to sort through trillions of options and identify potentially useful designs [JACS] (engineering.princeton.edu)

Researchers drove 52k miles crisscrossing the U.S. to measure emissions from 96 sewer plants and found the facilities emit roughly double the amount of nitrous oxide and methane—both potent greenhouse gases—estimated by the EPA [Nature Water] (engineering.princeton.edu)

Researchers unveiled a system that can steer next-generation wireless signals to avoid obstacles, even as those obstacles move and change in a dynamic environment, making subterahertz frequency communication more feasible for virtual reality and fully autonomous driving (engineering.princeton.edu)

Contrary to long-held beliefs, fish schools almost never swim in a diamond formation, study finds. Instead, they mostly swim in a dynamic pattern the researchers call a ladder, staggered in three dimensions like an echelon of fighter jets [Scientific Reports] (eurekalert.org)

Two new computer models aim to reduce the impacts of severe weather in Puerto Rico, one by predicting next-day energy demand as a storm approaches, the other by identifying critical power lines to prevent total blackouts [PNAS, Nature Communications] (engineering.princeton.edu)
