瑞典皇家科学院决定将2026年诺贝尔化学奖授予亨利·B·卡根和曾井健三，以表彰他们“在不对称有机合成中发现非线性效应和自催化现象”。

1953年，一位物理学家写下了一个三步配方，描述了分子的一只手如何“接管”整个分子。1986年，卡根完成了第二步。曾井健三完成了第三步。

化学学会了如何选择“手”。许多分子以两种镜像形式存在，但生命体只使用其中一种。卡根发现纯度并非呈直线增长；曾井健三发现了一种能够复制自身“手”的分子。

Sciences Behind 2026 Nobel Prize in Chemistry in 2 Minutes

The Royal Swedish Academy of Sciences has decided to award the 2026 Nobel Prize in Chemistry to Henri B. Kagan and Kenso Soai “for the discovery of non-linear effects and autocatalysis in asymmetric organic synthesis.”

In 1953 a physicist wrote a three-step recipe for how one hand of a molecule could take over. Kagan ticked step two in 1986. Soai ticked step three.

Chemistry learned to choose a hand. Many molecules come in two mirror-image forms, and life uses only one. Kagan found that purity doesn't add up in a straight line; Soai found a molecule that copies its own hand.
