To enable next-generation energy devices like fuel cells and water electrolyzers, researchers at the University of Chicago Pritzker School of Molecular Engineering (UChicago PME) collaborated with scientists at New York University to study the backbone chemistry of different types of ion-exchange membranes to better understand how their chemical make-up governs their structure and ability. They found that the nanostructures within these membranes evolve when water passes through and are affected by the stiffness of the polymer backbone. Different backbone architectures promote distinct ionic nanostructures, which govern how water is distributed within the membrane. Flexible backbones achieve higher ion conductivity with less water uptake, overcoming a trade-off that has long challenged membrane design. The results were published in the Journal of the American Chemical Society.
A new study reports that omega-3 fatty acids are highest in milk labeled as organic grass-fed and lowest in conventionally-produced milk. Other fatty acids varied by dairy production method and season.
Nearly one-quarter of teens reported using mobile food delivery services during school hours and almost half said they use them after school, according to a national survey of over 1,000 U.S. adolescents.
A new study from Carnegie Mellon University and Oxford Saïd Business School finds that the rollout of Uber and Lyft across 167 U.S. metropolitan areas triggered measurable, positive changes in local economies. Published in Nature Cities, the research reveals that the entry of these ride-hailing services consistently boosted regional GDP per capita and increased the availability of flexible, intermittent jobs. While overall employment and wage rates remained stable, the findings provide clear evidence that the gig economy expanded mobility and unlocked new regional economic activity.
A new study of an Israeli hospital's response to the October 7 attacks shows that while years of disaster training enabled staff to continue treating patients under rocket fire, real wartime conditions exposed critical gaps in communication, staffing, logistics, and casualty distribution. The findings offer practical lessons that could help hospitals worldwide prepare for prolonged armed conflicts and other large-scale emergencies.
