Since 2012, six bridges have collapsed in Mumbai, killing 28 people and injuring hundreds. Often, news of flyovers and pedestrian bridges tumbling down have made it to the headlines across the country. Although durable materials like steel and concrete are used in today’s structures, poor quality of construction and lack of maintenance are often blamed for such catastrophes. Contrast this with the rock-solid centuries-old root bridges found in Meghalaya—many as old as 250 years and still growing strong—built without modern tools or design. Could the structure of these bridges unravel architectural clues for urban construction? In a recent study, researchers from Germany and the USA have tried to understand the morphology and structure of these root bridges, built out of the aerial roots of strangler figs, and that have endured floods, earthquakes, landslides and fires.

Prof R B Sunoj of the Department of Chemistry of the Indian Institute of Technology Bombay has received the 2019 Shanti Swarup Bhatnagar Prize by Council of Scientific and Industrial Research (CSIR). The prize recognizes his outstanding contributions for providing molecular level insights on organic reaction mechanisms.

In a recent study, researchers from the Indian Institute of Technology Kanpur have explored the use of a new blend of chromium (III) as an eco-friendly electrolyte for depositing chromium-based coatings on metallic barrels. They reinforced chromium with carbon nanotubes (CNTs) and a ceramic compound called yttria stabilised zirconia (YSZ), to improve the properties of the coat.

Prof Subimal Ghosh, Professor at the Department of Civil Engineering, Indian Institute of Technology Bombay (IIT Bombay), has been awarded the Shanti Swarup Bhatnagar Prize 2019 by the Council of Scientific and Industrial Research (CSIR). This award recognises his significant contributions to our understanding of how land surface processes influence the Indian monsoon, as well as for improving regional monsoon simulations and predictions.
