Microbiologists have been growing microbes on agar plates for nearly 150 years, but agar’s discovery dates back to a happy accident in a mid-17th-century kitchen. Legend has it that on a cold winter day, a Japanese innkeeper cooked tokoroten soup, a Chinese agar seaweed recipe known in Japan for centuries. After the meal, the innkeeper discarded the leftovers outside and noticed the next morning that the sun had turned the defrosting jelly into a porous mass. Intrigued, the innkeeper was said to have boiled the substance again, reconstituting the jelly. Since this discovery, agar has become a staple in many Japanese desserts, from yokan to anmitsu.

青海都兰热水墓群出土的唐代扎经染色织物（斑布），在刘大玮团队的多重分析下揭开了扑朔迷离的身世：织物的主要原料来源于西南地区，生产则在东南和西南各地，经“认土做贡”制度被运至都城长安后，又以赏赐或贸易的形式流转至包括都兰在内的藩国、邻邦。作为陆上丝绸之路的重要见证，都兰纺织品的研究有力挑战了扎经染色织物“印度起源论”，更彰显了中华文明始终以开放的胸怀拥抱世界，在和平的商贸往来中慷慨待人的气质。
