Mapping the dairy matrix: Understanding how the physical structures in dairy foods uniquely fuel the human body
ElsevierHow do we determine how healthy our food is? We know now that our nutrition shouldn’t just be measured in calories, or even in just macronutrients (the balance of fats, protein, and carbohydrates). An emerging body of research is instead demonstrating that the unique interplay between nutrients and components and how they connect to each other to form a holistic food matrix all play a role in the nutritional value that foods deliver. A new review article in a special issue of the Journal of Dairy Science, published by Elsevier, dedicated to the dairy matrix and human nutrition explores what the latest science has to say about the incredible structural complexity of dairy foods, as well as the impact of the dairy food matrix on nutrient digestion and absorption.

Where there’s fire, there’s smoke
Harvard John A. Paulson School of Engineering and Applied SciencesPeer-Reviewed Publication
A new online platform, SMRT-Flames, can identify areas in need of land management in order to reduce future smoke exposures from uncontrolled fires. While most wildfire tools predict fire risk, SMRT-Flames explicitly considers smoke exposure across populations

Platform feedstock chemicals from global warming gas: a new paradigm in carbon utilization
Cactus CommunicationsPeer-Reviewed Publication
In a bold stride toward carbon neutrality, seven researchers from Gwangju Institute of Science and Technology (GIST), South Korea, unveil a novel catalytic reaction which selectively produces value-added alcohols from CO2 using electrochemical conversion. The cutting-edge technology enables mass production of high value-added feedstock chemicals with world-class efficiency (four times higher efficiency than those achieved till date)—laying the groundwork for a zero-carbon future.
