A recent study from the University of Kansas found that college students' self-reported attitudes towards sex on dates do not match their actual behavior. When men initiated dates, sex was more restricted than when women asked for a date. In contrast, female-initiated dates saw genital contact occurring on 63% of occasions, while tradi...
The Estée Lauder Companies has released its Green Score methodology to assess and measure the sustainability of ingredients and formulas based on green chemistry principles. The approach uses a quantitative tool to evaluate human health, ecosystem health, and environmental impact across its product portfolio.
Scientists at TUM and LSB developed a new methodology to quantify the flavor profile of cocoa samples. The method provides quantitative data on 66 taste-decisive substances using a single mass spectrometric platform, allowing analysis of 200 samples per week.
Researchers analyzed all relevant COVID-19 studies to determine if cardiovascular drugs affect disease severity, hospitalizations, and deaths. The study found that patients with COVID-19 should continue taking their prescribed cardiovascular medications.
Researchers developed SeSBAT, a computer program that analyzes magnetic resonance images to detect early signs of neurodegenerative diseases. The tool identifies biomarkers before symptoms appear, allowing for individualized monitoring and more accurate management.
In the INFORMS O.R. & Analytics Student Team Competition, student teams from around the world used operations research (OR) and analytics to optimize autonomous vehicle delivery processes for General Motors. The winning team from Korea Advanced Institute of Science and Technology minimized total costs while satisfying all constraints.
