To test their theory that the gut microbiome plays a role in the “senior moments” many of us experience, the researchers housed young (2-month-old) mice together with old (18-month-old) mice.

静寄山庄所藏梅杏主题作品，彼此交织，形成丰富而呼应的艺术图景。邹一桂《杏花图》以视觉定格历史瞬间；董诰《梅杏图》贴落则将诗句“梅兄杏弟江南例，杏主梅宾蓟北题”化为意象，装饰于雨花室墙壁。同一主题在不同媒介间流转，水墨、缂丝、贴落、题诗共同构建起立体化的艺术表达，使梅杏雅趣贯穿多种审美形式。同时通过精准控制温度、光照与水分，使梅花花期适配杏花绽放的自然节律，实现“梅杏同春”的观赏效果。这些盆栽花木本身即为“活的艺术”，其形态经精心设计，既契合盘山野趣，亦适合室内陈设，与壁上画作构成生动对话。
