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(AI)系统背后的研究人员赢得了今年300万美元的突破奖之一,这是科学领域最赚钱的奖项。伦敦DeepMind公司的德米斯·哈萨比斯和约翰·斯特沃因发明了一种预测地球上几乎所有已知蛋白质3D结构的工具而获奖。纽约哥伦比亚大学的计算生物学家Mohammed AlQuraishi说:“很少有发现能如此迅速地戏剧性地改变一个领域。”“它真的改变了结构生物学的实践,包括计算和实验。”该奖项是9月22日宣布的五个突破奖之一,用于奖励生命科学、物理学和数学领域的成就。AlphaFold的种子来自于DeepMind的AlphaGo的成功。这就是2016年在首尔击败围棋大师李世石(Lee Sedol)的人工智能。哈萨比斯表示:“这是游戏AI的巅峰,但它本身从未被认为是最终目标。“我想构建人工智能来加速科学发现。”从首尔回来的第二天,该团队就把注意力转向了蛋白质折叠。该系统在2020年11月击败约100个其他软件程序,赢得了两年一次的CASP竞赛(结构预测临界评估),引起了轰动。AlphaFold的早期版本在2018年获得了胜利,但并不令人信服,迫使该团队重新开始设计。“对于机器学习,它是关于在架构(已知基础科学施加的约束)和数据之间找到正确的平衡,”Jumper说。自DeepMind于2021年7月发布AlphaFold的开源版本以来,已有超过50万名研究人员使用了这一机器学习系统,生成了数千篇论文。今年7月,DeepMind发布了根据氨基酸序列预测的2亿个蛋白质结构。到目前为止,这些数据已被用于解决从抗生素耐药性到作物韧性等一系列问题。伦敦大学学院的计算生物学家Christine Orengo说:“这是一个重大突破,不仅因为他们开发了算法,还因为他们使算法可用,并提供了所有这些结构。”她补充说,这一成就是由全球社区收集的丰富蛋白质序列数据实现的。哈萨比斯说,当他得知自己获得了“突破奖”时,他感到“震惊”,而Jumper说他“不敢相信这是真的”。哈萨比斯计划将部分奖金捐赠给旨在增加多样性的教育项目,以及支持尼泊尔农村学校的倡议。另一项生命科学突破奖联合授予了日本筑波大学的睡眠科学家Yanagisawa Masashi和加州帕洛阿尔托斯坦福大学的Emmanuel Mignot,以表彰他们独立发现嗜睡症是由大脑化学物质食欲素缺乏引起的。哥本哈根大学的神经生理学家Birgitte Rahbek Kornum说,这两位研究人员都是“该领域的巨人”,他们使这种疾病得到了明确的诊断。她说:“嗜睡症严重影响生活质量,这让患者确切地知道哪里出了问题,而不是被告知‘控制住自己,保持清醒’。”这些发现也推动了目前正在进行临床试验的药物治疗的发展。柳泽说,他对获奖“深感荣幸”,并计划用这笔钱建立一个捐赠基金,为研究提供资金。他说:“对年轻科学家在日本从事探索性工作的稳定支持是有问题的。”他指出,他自己的发现之所以成为可能,只是因为他可以自由地“进行一次‘钓鱼考察’,但没有成功的保证”。 第三个生命科学奖由新泽西州普林斯顿大学的克利福德·布兰温和德国德累斯顿的马克斯·普朗克分子细胞生物学和遗传学研究所的安东尼·海曼共同获得,他们发现了一种细胞内容物通过分离成液滴自行组织的机制。今年的基础物理学突破奖由量子信息领域的四位创始人共同获得:位于剑桥的麻省理工学院的彼得·肖尔(Peter Shor);英国牛津大学的David Deutsch;纽约州约克镇IBM公司的查尔斯·班尼特;以及魁北克蒙特利尔大学的Gilles Brassard。他们的研究为超安全通信和计算机的发展奠定了基础,这些计算机有朝一日可能在某些任务上超越标准机器。肖尔说:“得知自己获奖时,我真的很惊讶。“其他人已经做了很多。”在20世纪90年代,肖尔开发了第一个可能有用的量子算法,该算法有朝一日可能使量子计算机能够快速地将大量数字分解为质因数。这增加了破解加密代码的可能性,这些代码用于保护当今大部分基于大素数的互联网通信。牛津大学的量子物理学家Nikita Gourianov说:“这个巨大的结果证明了量子计算机不仅仅是另一个学术上的好奇。”数学突破奖被授予康涅狄格州纽黑文耶鲁大学的数学家丹尼尔·斯皮尔曼。斯皮尔曼因多项进步而获得认可,包括开发了滤除高清电视广播噪音的纠错码。“突破奖”于2012年由俄罗斯裔以色列亿万富翁尤里·米尔纳(Yuri Milner)创立。他们现在得到了米尔纳和其他互联网企业家的赞助,包括Meta(前身为Facebook)的首席执行官马克·扎克伯格。本文经许可转载,首次发表于2022年9月22日。
