2025 Impact Report

All-in for accelerating discovery

Technology and innovation are fueling discovery in science like never before, and we’re proud to be leading the way. 2025 was a year of tremendous impact for our science, our communities, and our quest to understand life for a healthier world.

Mapping complexity

Understanding the whole requires understanding its parts. From brain regions to cell types, and the gene expression of our immune cells, mapping and defining the astounding complexity of biology and its vast molecular landscape is a critical step to understanding health and disease.

Biological building blocks

This year marked a watershed moment: Our researchers—along with a team of global collaborators—completed an eight-year, monumental effort to create a complete functional wiring diagram for a portion of the mouse brain. The MICrONS project maps half a billion synapses, over 200,000 cells, and some four kilometers of axons. It is a spectacular achievement once thought impossible that sheds light on the critical connections between form and function in the brain—fundamental knowledge that fuels understanding into diseases such as Alzheimer’s and neuropsychiatric conditions, leading us closer to answers that can change and save lives. Our researchers also completed detailed brain cell maps of aging in the mouse brain, and mammalian brain development that reveal the critical phases where the normal path can stray into disease. The fundamental insights contained in these cellular atlases and maps, along with the staggering detail and scale inherent to them, will empower researchers around the world to chart new research paths towards new treatments and therapies for disease.

Health and disease research

Our researchers have made exciting progress in disease research, more specifically, around a condition that robs the body of motor control and the mind of hope: ALS. But now, there is hope for new treatments and therapies for those who suffer from this terrifying condition as our scientists have discovered a way to target the precise cells that perish during the cruel progression of this disease. This opens the door to new drugs and therapeutics that can be designed and delivered directly to the affected cells, delivering treatment where it’s needed most.

Our scientists have also unearthed critical insights into rheumatoid arthritis, revealing the early warning signs that signal your body is fighting a silent battle. This foundational knowledge has the potential to lead to earlier diagnosis and new treatments that could stop the painful symptoms before they even begin. Our researchers also developed a successful gene replacement therapy for Dravet syndrome that was remarkably effective at halting the disease’s debilitating seizures in mice without side effects. This promising breakthrough could lead to successful treatments for this rare form of epilepsy in humans.

From lab to life

Where does health end and disease begin? This is the question driving our teams as they probe the mysteries of biology. With every new discovery, we lay the foundation for the treatments of tomorrow. The insights that our teams are uncovering, along with the related tools, resources, and datasets are advancing human health research for all.

Tools for discovery

Tools and technology fuel discovery, exponentially increasing our capacity to unearth critical insights into life and find breakthroughs that advance health. Better tools solve problems, shatter barriers to progress, increase capacity to decode life’s mysteries, and pave shorter paths to new treatments for disease. To support its moonshot science and catalyze discovery for researchers around the world, the Allen Institute has developed innovative biological, scientific, and digital tools that empower science for all.

Supporting the research community

New innovations such as CryoSCAPE have the potential to expand how fundamental research is done. CryoSCAPE is a tool that freezes blood samples into a state of suspended animation, allowing them to be transported over vast distances and over greater periods of time without degradation. This innovation offers “ground truth” insight into biology that will enable communities far from centers of science—those in rural and remote areas—to take part in clinical trials and benefit from the discoveries that result. Too often these communities are left out with little recourse.

This, along with the many other tools designed by our teams, help researchers solve problems that seem unsolvable, peer into worlds that appear unreachable, and turn data into knowledge and insight that leads to breakthroughs.

Shaping tomorrow’s biology

CellScapes is an ambitious, paradigm-shifting endeavor that could reshape our understanding of cellular biology. Its goal is to discover the universal principles and rules of cellular state change and behavior. Using theory, imaging, computation, and experimentation, CellScapes aims to understand and predict the behavior of human cells—understanding why they change as they do—as they orchestrate together to form tissues and organs. This foundational knowledge could illuminate exactly when and how cellular development goes catastrophically wrong in conditions like cancer, potentially unlocking life-saving interventions.

The edge of life

The pace of change and technological advancements in bioscience are moving at a frenzied pace. Never before in history has change been so alive and vigorous. In this exciting frontier of discovery, our collaborative, open scientific approaches to tackling the toughest challenges in biology are meeting this moment head on. We move faster and farther together. The foundational knowledge, data, and resources we are producing and sharing openly with the global scientific community is helping to answer the questions of tomorrow while changing how science is done today.

Science matters

Science touches every life on Earth. From vaccines that shield us from disease to antibiotics that fight them, scientific inquiry leads to innovations that keep us and our families healthy. This core message—that science matters—drives our public engagement efforts aimed at building a broad base of support for science and scientific inquiry.

Initiatives to support matters of science

At the Allen Institute, we not only do science, we champion it. We bring science directly into communities and to people in spaces where it has been absent with the goal of energizing and exciting new audiences. This work helps not only our researchers, but also the global scientific community, allowing us to move faster and farther together.

These future researchers will carry our foundational discoveries from the lab to communities where they will have real-world impact through new drugs and therapies for disease.

Accelerating Innovation

To accelerate the innovation and ideas that propel science forward, this year we launched the inaugural Allen Institute Innovation Awards. This bold initiative channels support to internal projects and collaborations poised to change the face of science and advance human health. Out of dozens of thoughtful submissions, four projects were selected to move forward, investigating and advancing new tools and technologies that could enhance our understanding of the brain and lead to more precise and effective therapies for disease, including new treatments for addiction and mental illness. From a competitive field of 40 ambitious proposals, these awards represent an exciting first—the beginning of what’s possible when visionary minds push the boundaries of human health.
