Microbes Take Their Vitamins—for the Good of Science
Scientists exploit organisms' needs to track "vitamin mimics" in bacteria

Scientists at Pacific Northwest National Laboratory have made a "vitamin mimic"—a molecule that looks and acts just like the natural vitamin to bacteria, but can be tracked and measured in live cells. The research offers a new window into the inner workings of living microbes crucial to the world's energy future, wielding great influence in the planet's carbon and nutrient cycle and serving as actors in the creation of new fuels.

Bringing New Light to a Transformative Protein
Combined approach used to investigate photophysics of green fluorescent protein

A substance from a jellyfish in the western coast of North America has transformed modern cellular biology. When added to viruses and proteins, green fluorescent protein (GFP), brings their life and function into view. Now, by combining experiment, computation, and theory, scientists at PNNL and Louisiana State University have discovered new insights about GFP's behavior. In turn, this can lead to even more ways to exploit this valuable monitor of biological processes.

Captured by the Game
Game theoretic approaches up the ante on defending cybersecurity resources

As the volume and intensity of cybersecurity incidents continue to escalate, anticipating and combating cyber attacks are increasingly critical. In ongoing work involving game theory conducted as part of PNNL’s Asymmetric Resilient Cybersecurity initiative, an award-winning team from the Laboratory’s National Security and Advanced Computing research areas presents a probabilistic modeling framework for representing and propagating uncertainties in cyber attacker payoffs with the added goal of increasing awareness about this problem domain. Ultimately, mathematical models, such as the proposed framework, will assist decision-makers in strategic planning to support effective and preemptive cyber system defense.
