In 1996, David Deamer and Daniel Branton’s labs at UC Santa Cruz and Harvard collaborated on a paper showing that when an electric current runs through a nanopore, passing purine (A and G) and pyrimidine (T and C) DNA bases through the nanopore disrupted the current to different degrees. While the technique couldn’t yet discriminate between all four bases, the general idea for a new single-molecule sequencing method was there.
传统绘画中，对于月亮的直接描绘并不多，但是表现上元节的绘画中有多幅绘制了月轮，丰富并拓展了元宵画境。刻画宫苑十二月景致的清代陈枚《月曼清游图册》之“寒夜探梅”（局部见图一），正是表现元夕之景。画面右上方，画家特意用暖黄色渲染一轮圆月，下方婀娜的仕女们在宫苑中举灯漫游，天上满月与廊檐悬挂的宫灯交相辉映。在月光和灯光下，盛开的星星点点的梅花和宫灯珠串一样晶莹，为画面增添一份灵动。南朝宗懔《荆楚岁时记》云：“始梅花，终楝花，凡二十四番花信风。”作为花信风之首，梅花在二十四种花里应了一个“元”字。梅花饰品亦是元夕佳节重要物品，早在宋代，元夕节便尚白衣、簪玉梅。该画作中洁白的梅花不仅是现实景观，更折射节日文化。
