Researchers at Osaka Metropolitan University have developed a straightforward method for predicting the measurement precision of fringe projection photogrammetry.

New research led by a York University professor sheds light on the earliest days of the earth’s formation and potentially calls into question some earlier assumptions in planetary science about the early years of rocky planets. Establishing a direct link between the Earth’s interior dynamics occurring within the first 100 million years of its history and its present-day structure, the work is one of the first in the field to combine fluid mechanics with chemistry to better understand the Earth's early evolution.  

Los Angeles has some of the strictest tree planting rules in the nation. These policies limit tree growth, worsen shade disparities and don’t improve safety, researchers found. When USC Dornsife researchers modeled looser planting restrictions in a lower-income neighborhood, potential tree space increased by nearly 26%. But narrow sidewalks and dense infrastructure still limited where larger, shade trees could thrive. Many of L.A.’s strict tree-spacing rules are internal guidelines — not laws — meaning they could be updated more easily to allow for more trees. Closing L.A.’s shade gap, however, will require more than policy tweaks; infrastructure investments are also needed.
