A Duke University theoretical chemist has developed a divide and conquer method to model electronic structures of large molecules with reduced calculations. The technique enables researchers to precisely describe electron interactions, providing a more refined picture of molecule behavior.
A Penn State poultry nutritionist is developing strategies to balance chicken diets and minimize manure production, reducing nitrogen and phosphorus waste. The approach involves adjusting feed formulation, using better feed additives, and tailoring feeds to the life cycle of birds.
An international team of scientists conducted a study on air pollution in Mexico City's basin, where inversions trap pollutants and fine particles pose significant health risks. The study provides insights into particle concentrations, transport patterns, and implications for U.S. cities.
A national study found that strong family and school connections help protect adolescents from substance abuse, early sexual activity, and other risks. Feeling connected to parents, teachers, and peers is key to avoiding these behaviors.
Researchers developed a program to target high-sensation seeking teens, showing promise in reducing illicit drug use among adolescents. The study found decreased use of liquor and marijuana, increased perceived risks of substance abuse, and a greater increase in negative attitudes towards drugs for high-sensation seekers.
