ABOUT
Biosecurity in the Fourth Eon
Fourth Eon develops research, tools, and screening infrastructure to help society anticipate and reduce emerging risks from biological design technologies.
Biology is becoming programmable. AI systems can increasingly model, design, and modify biological function, creating extraordinary new capabilities and new classes of risk.
The machinery of life evolved over four billion years, producing the ability to encode, replicate, and adapt. Now, for the first time, intelligence can engineer that machinery directly.

Fourth Eon builds the screening tools, models, and safeguards that need to keep pace with what biology can now do. Three eons shaped life through evolution. The fourth is shaped by intelligence engineering biology directly.
This is the mission of Fourth Eon Biosecurity.

RESEARCH
Adaptive Biosecurity Infrastructure
Fourth Eon Biosecurity is a research and development organization exploring capabilities, applications, and risks of AI bio models to advance global biosecurity and build adaptive safeguards.

AIXBIO
Exploring AI protein design risk
Biological foundation models and biodesign tools are transforming our ability to create novel proteins and pushing the boundaries of synthetic biology. They also pose new challenges for biosecurity due to the potential for engineering dangerous functions.
— + —
Fourth Eon is evaluating AI-enabled protein design in the context of biosecurity screening, and seeking to understand the capabilities of current models in generating novel proteins that could challenge existing safeguards.

SYNTHESIS SCREENING
Developing function-based sequence screening
DNA synthesis screening is central to detecting hazardous biological function before it’s built. DNA sequences encode a highly compressed representation of biological function, which is executed by the cellular environment through the processes of molecular biology. Screening sequences for hazardous functions has traditionally relied on homology to known genes and proteins, but this approach is being strained as synthetic biology pushes beyond the space explored by nature.
— + —
Biological foundation models can learn a rich and nuanced representation of biomolecules by mapping their sequence-structure-function relationships to a high-dimensional embedding space. Fourth Eon is evaluating foundation model capabilities for predicting structure, binding, function, and other molecular properties directly from sequence, and exploring how this could be used for detecting biological threats that do not closely resemble anything found in nature.
