ノーベル化学賞に硤合憲三さん!生命のナゾにせまる「硤合反応」とは

A Nobel Prize for a Japanese Chemist

音声・ゲームはこちらから

1A Japanese chemist has won the 2026 Nobel Prize in Chemistry. Kenso Soai is a professor emeritus at Tokyo University of Science. He will share the prize with Henri Kagan, another chemist.

2Many molecules have two forms. The two forms are like your left and right hands. They look almost the same, but they are mirror images. In living things, most of these molecules come in only one form.

3Soai found a special chemical reaction. In the reaction, the new molecule helps to make more of itself. It is called the Soai reaction. It may help explain a mystery about how life began.

4Soai was born in Hiroshima Prefecture in 1950. At a news conference, he thanked his students. He also said he was very happy to share the prize with Kagan.

全文訳

1日本の化学者が、2026年のノーベル化学賞に選ばれました。硤合憲三さんは、東京理科大学の名誉教授です。硤合さんは、別の化学者アンリ・カガンさんと賞を分け合います。

2多くの分子には、2つの形があります。その2つの形は、左手と右手のような関係です。ほとんど同じに見えますが、鏡に映したように反対になっています。生き物の体の中では、こうした分子のほとんどが片方の形だけになっています。

3硤合さんは、特別な化学反応を見つけました。その反応では、できた分子が、自分と同じ分子をさらに作る手助けをします。これは「硤合反応」と呼ばれています。この反応は、生命がどのように始まったかというナゾの説明に役立つかもしれません。

4硤合さんは1950年に広島県で生まれました。記者会見で、硤合さんは学生たちに感謝しました。また、カガンさんと賞を分け合えてとてもうれしいと話しました。

文法ポイント:受け身(be called ~:~と呼ばれる)

be動詞 + called + 名前 で「~と呼ばれている」を表す。本文の It is called the Soai reaction. は「それは硤合反応と呼ばれている」という意味。
