Its mirror twin exists too — but life almost never uses it.\u003C\u002Fp>\n\u003Cp style=\"margin:0 0 18px;\">On October 7, 2026, the Royal Swedish Academy of Sciences awarded the Nobel Prize in Chemistry to Henri B. Kagan of France and Kenso Soai of Japan, \"for the discovery of non-linear effects and autocatalysis in asymmetric organic synthesis.\"\u003C\u002Fp>\n\u003Cp style=\"margin:0 0 18px;\">They cracked one of chemistry's oldest riddles: how chemical asymmetry — homochirality — ever came to be.\u003C\u002Fp>\n\u003Ch2 style=\"color:#111;font-size:21px;line-height:1.4;margin:28px 0 12px;\">\u003Cstrong>The Mirror Mystery\u003C\u002Fstrong>\u003C\u002Fh2>\n\u003Cp style=\"margin:0 0 18px;\">Certain molecules, like amino acids, exist in two mirror-image variants. Yet living organisms contain only one of the two mirrors.\u003C\u002Fp>\n\u003Cp style=\"margin:0 0 18px;\">How did this chemical asymmetry arise? For a long time, chemists could not solve the puzzle.\u003C\u002Fp>\n\u003Cp style=\"margin:0 0 18px;\">Life's chemistry is what chemists call \u003Cstrong>homochirality\u003C\u002Fstrong> — a term from the Greek words for \"same\" and \"hand.\" Like your two hands, all amino acids exist as two mirror-image isomers, but only one of them appears in the proteins inside your cells. The other is extremely rare in nature.\u003C\u002Fp>\n\u003Cp style=\"margin:0 0 18px;\">Chemists were puzzled by where homochirality came from. When they ran reactions that could produce both mirror-image molecules, the test tube always returned equal amounts of the two forms. Yet chemists wanted to produce just one mirror form — because when developing molecules that interact with living organisms, such as drugs, only one mirror form produces the intended effect.\u003C\u002Fp>\n\u003Cp style=\"margin:0 0 18px;\">\u003Cimg src=\"\u002Fattachment\u002F20261007\u002F6729cdf22e8241a7b6fa1ab6dae6a9a9.webp\" alt=\"img_01.webp\">\u003C\u002Fp>\n\u003Ch2 style=\"color:#111;font-size:21px;line-height:1.4;margin:28px 0 12px;\">\u003Cstrong>Kagan's First Step: A Non-Linear Effect\u003C\u002Fstrong>\u003C\u002Fh2>\n\u003Cp style=\"margin:0 0 18px;\">In 1986, Henri Kagan took the decisive first step. He found a new way to steer a chemical reaction — a method that produced far more of one mirror isomer than anyone had thought possible.\u003C\u002Fp>\n\u003Cp style=\"margin:0 0 18px;\">His discovery became known as the non-linear effect: combine equal amounts of left and right enantiomers in a catalyst, and the catalyst can actually enhance the reaction's asymmetry. The proportions shift — the catalyst ends up driving the reaction far more toward one mirror form than the starting mixture would suggest.\u003C\u002Fp>\n\u003Cp style=\"margin:0 0 18px;\">\u003Cimg src=\"\u002Fattachment\u002F20261007\u002Fb7c4c56c03d944baafe0eccb7fb6559f.webp\" alt=\"img_02.webp\">\u003C\u002Fp>\n\u003Cp style=\"margin:0 0 18px;\">For chemists designing reactions to make medicines, perfumes, flavors, and new materials, this was revolutionary.\u003C\u002Fp>\n\u003Ch2 style=\"color:#111;font-size:21px;line-height:1.4;margin:28px 0 12px;\">\u003Cstrong>Soai's Breakthrough: Life-Like Self-Replication\u003C\u002Fstrong>\u003C\u002Fh2>\n\u003Cp style=\"margin:0 0 18px;\">Kenso Soai went one step further. In 1995, a key paper described how he had designed the first chemical reaction capable of producing a homochiral outcome. Then, in 2003, he succeeded.\u003C\u002Fp>\n\u003Cp style=\"margin:0 0 18px;\">He demonstrated a reaction in which only one of the two possible mirror products was formed. Before that, only life itself had ever achieved this feat.\u003C\u002Fp>\n\u003Cp style=\"margin:0 0 18px;\">The Soai reaction is a self-reinforcing process: the reaction starts with a non-chiral solution, forms a chiral catalyst, and that catalyst then drives its own formation. Add more substrate and reagent, and the process repeats — the dominant enantiomer rapidly takes over.\u003C\u002Fp>\n\u003Cp style=\"margin:0 0 18px;\">In one experiment, Soai started with a tiny excess of one enantiomer — just 0.00005%. After three rounds, that enantiomer made up more than 99.5% of the product.\u003C\u002Fp>\n\u003Cp style=\"margin:0 0 18px;\">\u003Cimg src=\"\u002Fattachment\u002F20261007\u002F091d7fecd3524ce99821bf1e8a6247ab.webp\" alt=\"img_03.webp\">\u003C\u002Fp>\n\u003Cp style=\"margin:0 0 18px;\">\"Besides life itself, no one had ever done this before,\" the Nobel committee noted.

The non-linearity reveals information about how a reaction works. With that information, chemists can optimize reactions to obtain the highest-purity enantiomer of a product. This matters enormously for every company producing substances that interact with living organisms — medicines, fragrances, flavors, and agrochemicals — and in some cases, for producing new materials.\u003C\u002Fp>\n\u003Cp style=\"margin:0 0 18px;\">The Soai reaction has ignited fresh enthusiasm among chemists studying the origin of life.
