China’s double threat, a hidden card in the trade war: 7 science highlights
From an ancient scroll being brought back to life to China’s rail line to potassium in Laos, here are some highlights from SCMP’s recent science reporting

1. ‘Potassium railway’: China’s hidden card in the trade war
For over a decade, China has invested heavily to build a dual-purpose passenger and freight railway through the thick rainforest between Kunming and Vientiane, the capital of Laos. This railway has become a critical conduit for China to secure potassium – a strategic resource vital for agricultural production.
2. Chinese Nobel Prize-winning physicist Chen-ning Yang dies aged 103
