Finding Stars: Mapping the Geography of the World's Scientific Elites

Transactions of the Institute of British Geographers, EarlyView.
Short Abstract Scientific excellence is clustering ever more tightly in a few ‘superstar’ cities. Four—New York, Boston, London and the San Francisco Bay Area—now host 12% of the world's top scientists. In contrast, the Global South remains largely absent, with the notable exception of Beijing's dramatic rise.

Comparison of Uptake of Cadmium at Low Concentrations Under Hydroponic and Soil‐Based Agriculture Systems for Lettuce, Indian Spinach and Methi

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 1, March 2026.
ABSTRACT Using recycled water for agriculture offers a sustainable approach by adding inherent nutrients and moisture to the soil. However, it contains unwanted contaminants such as heavy metals like cadmium at lower concentrations. This study assessed the comparative response of three leafy crops ‐ lettuce, Indian spinach and methi, against cadmium ...

Sedimentary records of palaeohydrological variability during the Late Holocene in the Lower Narmada Basin, western India

The Depositional Record, Volume 12, Issue 1, February 2026.
Late Holocene palaeohydrological changes in the lower Narmada Basin, India, revealed using multiproxy analyses of the Orsang River terrace sediments. Distinct depositional phases corresponding to global climatic events were recorded. High‐magnitude floods in the Narmada River during the MWP, and within the tributary Orsang River during DACP and LIA ...
