Scientists estimate sunlight in 18th and 19th century Tokyo using historical diaries
Research Organization of Information and SystemsSunlight, or solar radiation, is a critical factor in determining local weather, crop productivity, and climate. Before current instruments were available to accurately and automatically determine solar radiation at a given location, daily weather diaries were kept in Japan by aristocrats and farmers alike. A research team leveraged a digitized daily weather diary to estimate the solar radiation in Tokyo between 1720 and 1912, and validated the data against estimation from observed sunshine duration since 1896. The analysis detected two periods of low sunlight that coincided with two famines in Tokyo’s history.

Study: Immigrants help address the US eldercare shortage
Massachusetts Institute of TechnologyA study of U.S. metro areas shows changes in immigration levels can affect how much nursing care the elderly receive. When there is more immigration, registered nurses and other aides work more hours at nursing homes, without displacing already-employed caregivers, and patient outcomes improve.

New open-source tool quantifies uncertainty in green-hydrogen economics
Shanghai Jiao Tong University Journal CenterHydrogen, recognized as a critical energy source, requires green production methods, such as proton exchange membrane water electrolysis (PEMWE) powered by renewable energy. This is a key step toward sustainable development, with economic analysis playing an essential role. Life cycle costing (LCC) is commonly used to evaluate economic feasibility, but traditional LCC analyses often provide a single cost outcome, which limits their applicability across diverse regional contexts. To address these challenges, a Python-based tool is developed in this paper, integrating a bottom-up approach with net present value (NPV) calculations and Monte Carlo simulations. The tool allows users to manage uncertainty by intervening in the input data, producing a range of outcomes rather than a single deterministic result, thus offering greater flexibility in decision-making. Applying the tool to a 5 MW PEMWE plant in Germany, the total cost of ownership (TCO) is estimated to range between €52 million and €82.5 million, with hydrogen production costs between 5.5 and 11.4 €/kg H2. There is a 95% probability that actual costs fall within this range. Sensitivity analysis reveals that energy prices are the key contributors to LCC, accounting for 95% of the variance in LCC, while iridium, membrane materials, and power electronics contribute to 75% of the variation in construction-phase costs. These findings underscore the importance of renewable energy integration and circular economy strategies in reducing LCC.
