Charles Bennett and Gilles Brassard Receive 2025 ACM A.M. Turing Award
Charles H. Bennett and Gilles Brassard received the 2025 ACM A.M. Turing Award for their essential role in establishing the foundations of quantum information science and transforming secure communication and computing. Their work has influenced cryptography, algorithm design, computational complexity, learning theory, interactive proofs, and mathematical physics, while their research helped catalyze a generation of physicists and computer scientists to work across disciplinary boundaries. Bennett is an American physicist at IBM Research. Brassard is a Canadian computer scientist at the Université de Montréal.
Ricardo Baeza-Yates Receives 2025 ACM Barroso Award
ACM has named Ricardo Baeza-Yates the recipient of the 2025 ACM Luiz André Barroso Award for his pioneering contributions to algorithms and information retrieval as well as his leadership in fostering a vibrant transnational research community across Latin America. Baeza-Yates, a native of Chile, is currently the Search Chief Scientist at You.com, holding part-time professor appointments at KTH Royal Institute of Technology (Sweden), Universitat Pompeu Fabra (Spain) and Universidad de Chile.
In Memoriam: Michael O. Rabin
April 15, 2026
ACM A.M. Turing Award laureate Michael O. Rabin has passed away at the age of 94. Rabin, along with Dana S. Scott, recieved the Turing Award for their joint paper "Finite Automata and Their Decision Problem," which introduced the idea of nondeterministic machines and proved to be an enormously valuable concept. Their classic paper has been a continuous source of inspiration for subsequent work in this field. Rabin was an ACM Fellow, and also received the ACM Paris Kanellakis Theory and Practice Award for the development of efficient randomized tests of primality.
Message from ACM President Yannis Ioannidis about ACM's Transition to OA and Recent Changes to the ACM DL
ACM’s recent transition to open access and changes to the ACM Digital Library have sparked considerable community reaction and engagement. ACM President Yannis Ioannidis asks that you please take the time to read his response.
A Message to the Computing Community About ACM's Transition to Full Open Access
ACM is pleased to share an important milestone for the computing field. As of January 2026, all ACM publications and related artifacts in the ACM Digital Library have been made open access. This change reflects the long-standing and growing call across the global computing community for research to be more accessible, more discoverable, and more reusable. This transition is the result of extensive dialogue with authors, SIG leaders, editorial boards, libraries, and research institutions worldwide. ACM is grateful for the community’s consistent advocacy for openness and its commitment to ensuring that computing knowledge is shared widely.
We Must Teach Computer Science in Prison
Those of us who are not directly impacted by the criminal justice system may not (consciously choose to) think about prisons much, but are likely to absorb messaging that people in prison are inherently bad, dangerous, or undeserving of basic human rights. Teaching computer science in prison is a particularly meaningful way to change this. In this article from the May issue of Communications of the ACM, Emma Hogan Benser addresses this issue.
CACM Special Section: Federal Funding of Academic Research
Technological innovation is not just a byproduct of American ingenuity—it is its driving force. Most of the United States' 20th-century productivity growth stemmed from domestic breakthroughs in science and technology. And it is federal funding of basic research which has sparked and sustained the modern technological revolution. Yet despite the extraordinary returns of this investment, federal support for basic research is being sharply curtailed. This special section of Communications of the ACM raises the critical question: Can America remain a global innovation powerhouse if it sidelines the very engine that powered past progress?
ACM Queue Spotlight
In the latest edition of ACM's magazine for practicing software engineers: Memory safety—the property that makes software devoid of weaknesses such as buffer overflows, double-frees, and similar issues—has been a popular topic in software communities over the past decade and has gained special prominence alongside the rise of the Rust programming language. But if you're not yet sold on its value, "Memory Safety for Skeptics" by Andrew Lilley Brinker is for you. The goal of the article is to treat the question of pursuing memory safety in legacy systems with the seriousness and rigor that it deserves—and as worthwhile with or without Rust.
ACM Reaffirms Its Commitment to Our Mission and Core Values
ACM is aware that many in our community are concerned about potential negative effects of recent Executive Orders by the new US Administration on our work in both the US and globally. This includes concerns about possible consequences for ACM publishing, conferences, education, and practitioner efforts, as well as concerns about possible harms to our work on inclusion for a strong and diverse technology workforce.
ACM reaffirms its commitment to our mission and core values in all our scientific and educational activities. This includes global scientific and educational efforts dedicated to advancing the art, science, engineering, and application of computing. We will continue to serve both professional and public interests by fostering the open exchange of information and by promoting the highest professional and ethical standards.
ACM’s commitment to its mission, guided by its core values, is unchanged. We will work with members of the community to understand how new Executive Orders may affect their work as it relates to scientific, educational, and community development efforts.
Become an Ambassador for ACM
Encourage your colleagues to join ACM, share the benefits of ACM and receive free gifts for participating. Your support of ACM is critical to our continuing efforts to advance computing as a science and a profession.
ACM Code of Ethics
The ACM Code of Ethics and Professional Conduct was updated in 2018 to address the significant advances in computing technology since the 1992 version, as well as the growing pervasiveness of computing in all aspects of society.
Lifelong Learning
ACM offers lifelong learning resources including online books and courses from Skillsoft, TechTalks on the hottest topics in computing and IT, and more.
