Công trình đoạt Nobel Y học giải mã cơ chế của đồng hồ sinh học

Giải Nobel Y học 2017 đã thuộc về ba nhà khoa học người Mỹ gồm Jeffrey C.Hall, Michael Rosbash và Michael W.Young với những phát hiện về cơ chế phân tử kiểm soát nhịp sinh học, hay còn gọi là đồng hồ sinh học của cơ thể. Ủy ban Nobel Y học của Thụy Điển đánh giá: "Những phát hiện trong công trình nghiên cứu của 3 nhà khoa học trên đã giúp giải thích cách thức các loài động, thực vật và con người có thể thích nghi nhịp sinh học của mình, từ đó phù hợp với sự tiến hóa của Trái Đất."

Trong nhiều năm qua, các nhà khoa học đã nhận thức được rằng mỗi cá thể sống, bao gồm cả con người, có một chiếc "đồng hồ" ngay bên trong cơ thể mình, giúp các cá thể có thể dự đoán và thích nghi với nhịp điệu của một ngày. Đây là đồng hồ sinh học, còn gọi nhịp điệu sinh lý, vòng tuần hoàn sinh học 24h giúp cơ thể của chúng ta thích nghi với chu trình sáng, tối của ngày và đêm. Đồng hồ sinh học ảnh hưởng đến những chức năng quan trọng của cơ thể như mức độ hormone, giấc ngủ, nhiệt độ cơ thể và sự trao đổi chất.
