The researchers behind the AlphaFold artificial-intelligence (AI) system have won one of this year’s US$3-million Breakthrough prizes—the most lucrative awards in science. Demis Hassabis and John Jumper, both at DeepMind in London, were recognized for creating the tool that has predicted the 3D structures of almost every known protein on the planet.

“Few discoveries so dramatically alter a field, so rapidly,” says Mohammed AlQuraishi, a computational biologist at Columbia University in New York City. “It’s really changed the practice of structural biology, both computational and experimental.”

The award was one of five Breakthrough prizes—awarded for achievements in life sciences, physics and mathematics—announced on 22 September.

Award-winning AI

AlphaFold was seeded from the success of DeepMind’s AlphaGo. This was the AI that in 2016 beat Lee Sedol, a master of the strategy game Go, in Seoul. “That was the pinnacle of gaming AI, but that was never supposed to be an end in itself,” says Hassabis. “I wanted to build AI to accelerate scientific discovery.” The day after returning from Seoul, the team turned its attention to protein folding.

The system created a stir in November 2020 by winning the biennial CASP contest (Critical Assessment of Structure Prediction), beating around 100 other software programs. An earlier version of AlphaFold had won in 2018, but not convincingly, forcing the team back to the drawing board. “With machine learning, it’s about finding the right balance between the architecture—the constraints imposed by the known underlying science—and the data,” says Jumper.

Since DeepMind released an open-source version of AlphaFold in July 2021, more than half a million researchers have used the machine-learning system, generating thousands of papers. In July this year, DeepMind released 200 million protein structures predicted from amino-acid sequences. So far, the data have been harnessed to tackle problems ranging from antibiotic resistance to crop resilience.

“This is a major breakthrough, not just because they developed the algorithm, but because they made it available and provided all those structures,” says Christine Orengo, a computational biologist at University College London. She adds that the achievement was made possible by a wealth of protein sequence data gathered by the global community.

Hassabis says that he was “stunned” to learn he had won a Breakthrough prize, and Jumper says he “could not believe it was for real”. Hassabis plans to donate some of his winnings to educational programmes aimed at increasing diversity, and also to initiatives supporting schools in rural Nepal.

Sleep science and cellular systems

Another life-sciences Breakthrough prize was awarded jointly to sleep scientists Masashi Yanagisawa at the University of Tsukuba, Japan, and Emmanuel Mignot at Stanford University in Palo Alto, California, for independently discovering that narcolepsy is caused by a deficiency of the brain chemical orexin.

Both researchers are “giants of the field” who enabled the condition to be definitively diagnosed, says Birgitte Rahbek Kornum, a neurophysiologist at the University of Copenhagen. “Narcolepsy severely affects quality of life, and this allowed patients to know exactly what’s wrong, instead of being told to ‘get a grip and stay awake’,” she says. The findings have also led to the development of drug treatments that are currently in clinical trials.

Yanagisawa says he is “deeply honoured” by the prize and plans to use the money to set up an endowment to fund research. “Stable support for young scientists to do exploratory work in Japan is problematic,” he says, noting that his own discovery was possible only because he was free to “go on a ‘fishing expedition’ with no guarantee of success”.

A third life-sciences prize is shared by Clifford Brangwynne at Princeton University in New Jersey and Anthony Hyman at the Max Planck Institute of Molecular Cell Biology and Genetics in Dresden, Germany, for discovering a mechanism by which cell contents can organize themselves by segregating into droplets.

Quantum pioneers

This year’s Breakthrough Prize in Fundamental Physics is shared between four founders of the field of quantum information: Peter Shor at the Massachusetts Institute of Technology in Cambridge; David Deutsch at the University of Oxford, UK; Charles Bennett at IBM in Yorktown, New York; and Gilles Brassard at the University of Montreal in Quebec. Their research laid the groundwork for the development of ultra-secure communications and computers that might one day outperform standard machines at some tasks.

“I was really surprised to learn I have been awarded the prize,” says Shor. “There is so much that others have done.” In the 1990s, Shor developed the first potentially useful quantum algorithm, which could one day enable quantum computers to speedily break large numbers down into their prime factors. This raises the possibility of cracking encryption codes used to secure much of today’s Internet traffic, which are based on large prime numbers. “This massive result proved that quantum computers were more than just another academic curiosity,” says Nikita Gourianov, a quantum physicist at the University of Oxford.

The Breakthrough Prize in Mathematics goes to Daniel Spielman, a mathematician at Yale University in New Haven, Connecticut. Spielman was recognized for multiple advances, including the development of error-correcting codes to filter out noise in high-definition television broadcasts.

The Breakthrough prizes were founded in 2012 by Yuri Milner, a Russian-Israeli billionaire. They are now sponsored by Milner and other Internet entrepreneurs, including Mark Zuckerberg, the chief executive of Meta (formerly Facebook).

AlphaFold开发者赢得生命科学突破奖300万美元
AlphaFold人工智能系统的研发团队荣获了今年300万美元的突破奖(Breakthrough Prize)之一,这是科学领域奖金最高的奖项。来自伦敦DeepMind公司的Demis Hassabis和John Jumper因开发出能够预测地球上几乎所有已知蛋白质3D结构的工具而受到表彰。哥伦比亚大学的计算生物学家Mohammed AlQuraishi表示:“很少有发现能如此迅速而深刻地改变一个领域。”他补充道:“它真正地改变了结构生物学的实践方式,无论是计算还是实验方面。”9月22日宣布的五个突破奖分别授予生命科学、物理学和数学领域的成就。获奖的人工智能AlphaFold建立在DeepMind旗下AlphaGo的成功基础上。2016年,这款人工智能在首尔战胜了围棋高手李世石。Hassabis表示:“当时那是游戏人工智能的巅峰,但那绝不是终点。”他说道,“我真正想用人工智能加速科学发现。”从首尔回来后的第二天,团队就将注意力转向了蛋白质折叠问题。2020年11月,该系统在双年举行的CASP竞赛(结构预测关键评估)中引起轰动,击败了约100个其他软件程序。此前,2018年AlphaFold的一个早期版本也曾获胜,但成绩并不令人信服,迫使团队重新从头开始。“在机器学习中,关键在于找到架构——由已知科学原理设定的限制——与数据之间的正确平衡。”Jumper说道。自2021年7月DeepMind发布开源版本的AlphaFold以来,已有超过50万名研究人员使用了这一机器学习系统,并据此发表了数千篇论文。今年7月,DeepMind发布了2亿个根据氨基酸序列预测的蛋白质结构。迄今为止,这些数据已被用于解决从抗生素耐药性到作物抗逆性的各种问题。伦敦大学学院的计算生物学家Christine Orengo表示:“这是一个重大突破,不仅因为开发出了算法,还因为将其公之于众,并提供了所有这些结构。”她补充道,这一成就的实现得益于全球科学界积累的大量蛋白质序列数据。Hassabis表示自己得知获得突破奖时感到“震惊”,而Jumper则表示他“难以相信这是真的”。Hassabis计划将部分奖金捐赠给旨在提高多样性的教育项目,并支持尼泊尔乡村学校的相关工作。睡眠科学和细胞系统另一个生命科学突破奖颁发给了日本筑波大学的睡眠科学家Masashi Yanagisawa和位于美国加州帕洛阿尔托斯坦福大学的Emmanuel Mignot,他们各自独立发现,发作性睡病是由于大脑化学物质食欲素(orexin)的缺乏所致。哥本哈根大学的神经生理学家Birgitte Rahbek Kornum称这两位科学家是该领域的“巨人”,他们的工作使该疾病可以被明确诊断。“发作性睡病严重影响生活质量,而这让患者确切知道自己出了什么问题,而不仅仅是被告知要‘坚强些,别睡着’。”她说。这些发现还促成了目前正在临床试验中的药物治疗方法。Yanagisawa表示他“深感荣幸”获得该奖,并计划用奖金设立基金,资助研究工作。“日本对年轻科学家进行探索性工作的稳定支持是存在问题的,”他表示,并指出自己的发现之所以可能,是因为他可以自由地“进行一场‘钓鱼探险’,即使没有成功保障。”第三项生命科学奖由新泽西州普林斯顿大学的Clifford Brangwynne和德国德累斯顿马克斯·普朗克分子细胞生物学与遗传学研究所的Anthony Hyman共同获得,他们发现了一种机制,通过该机制,细胞内容物可以通过分离成液滴进行自我组织。量子先驱者今年的基础物理突破奖由量子信息领域的四位奠基人分享:剑桥麻省理工学院的Peter Shor;英国牛津大学的David Deutsch;纽约州约克镇IBM的Charles Bennett;以及加拿大蒙特利尔大学的Gilles Brassard。他们的研究为超安全通信系统和可能在某些任务上超越传统计算机的量子计算机奠定了基础。“得知自己获奖我真的非常惊讶,”Shor表示,“因为其他人也做了很多工作。”1990年代,Shor开发出了首个可能具有实际用途的量子算法,该算法有一天或许能帮助量子计算机快速地将大数分解为其质因数。这将使当今互联网流量所依赖的基于大质数的加密技术面临破解风险。“这一重大成果证明,量子计算机不仅仅是学术上的一个好奇。”牛津大学的量子物理学家Nikita Gourianov说道。数学突破奖则授予康涅狄格州纽黑文耶鲁大学的Daniel Spielman。Spielman因多项成就受到表彰,包括开发出用于高清电视广播中去除噪声的纠错码。突破奖由俄罗斯-以色列亿万富翁尤里·米纳尔(Yuri Milner)于2012年创立,目前由米纳尔与其他互联网企业家(包括Meta首席执行官马克·扎克伯格)共同资助。本文经授权转载,首次发表于2022年9月22日。
