Researchers developed the pedestrian movement index to capture pedestrian count, distance walked, and time spent in metro station areas using large-scale Global Positioning System data. This index elucidates the relationship between pedestrian behavior and various urban-space elements (such as density, diversity, design, accessibility, and distance). ​Researchers developed the pedestrian movement index to capture pedestrian count, …

Switching to ammonia as a marine fuel, with the goal of decarbonization, can instead create entirely new problems. This is shown in a study where researchers carried out life cycle analyses for batteries and for three electrofuels including ammonia. Eutrophication and acidification are some of the environmental problems that can be traced to the use …

Scientists have found a way to boost ethanol production via yeast fermentation, a standard method for converting plant sugars into biofuels. Their approach relies on careful timing and a tight division of labor among synthetic yeast strains to yield more ethanol per unit of plant sugars than previous approaches have achieved. ​Scientists have found a …
