In the world of modern science, the microscope and the telescope are now joined by the supercomputer. Discover how artificial intelligence, automation, and powerful data systems are revolutionizing scientific research.
At the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab), a revolution is underway, one powered by artificial intelligence, automation, and powerful data systems. This isn't just an upgrade to existing tools; it's a fundamental shift in how science is done, transforming the slow, methodical pace of discovery into a process that is faster, smarter, and capable of tackling some of the universe's biggest mysteries.
Machine learning algorithms accelerate hypothesis generation and testing
Robotic systems work tirelessly to synthesize and test new materials
High-performance computing enables complex simulations and analysis
Gone are the days when scientific discovery relied solely on a researcher at a lab bench. At Berkeley Lab, AI and robotics have become indispensable partners, taking over repetitive tasks and opening new frontiers in materials science.
At the heart of this shift is the A-Lab, an automated materials discovery facility. Here, AI algorithms dream up new chemical compounds, and robotic systems work tirelessly to prepare and test them. This creates a tight, high-speed loop between digital design and physical creation, drastically shortening the years-long process of discovering new materials for next-generation batteries, electronics, and energy solutions3 .
Running massive research facilities like particle accelerators and light sources requires extreme precision. AI is now stepping in to optimize these instruments in real time. At the Berkeley Lab Laser Accelerator (BELLA), machine learning models fine-tune and stabilize laser and electron beams, improving performance while reducing the need for constant manual calibration3 .
Similarly, the Advanced Light Source is integrating deep-learning controls to ensure it delivers one of the world's brightest X-ray beams for countless experiments3 .
Modern scientific instruments generate data on a previously unimaginable scale. Berkeley Lab's computing prowess ensures that this deluge of information becomes a stream of immediate insights.
A platform called Distiller exemplifies this speed. At the Molecular Foundry's National Center for Electron Microscopy, data collected from a powerful microscope is streamed directly to the Perlmutter supercomputer at the National Energy Research Scientific Computing Center (NERSC). What once took days or weeks now happens in minutes, allowing researchers to analyze results and adjust the experiment while it is still running. This real-time decision-making saves precious time and resources, accelerating the entire scientific workflow3 .
This computational muscle is also tackling grand challenges like nuclear fusion. At NERSC, machine learning models are being used to predict the behavior of particles in superheated fusion plasmas. These models have the potential to one day inform live control systems for future fusion reactors, bringing us closer to a virtually limitless source of clean energy3 .
From days to minutes: Accelerating scientific discovery through instant data processing
The quest to measure the mass of the neutrino—an elusive, ghost-like subatomic particle—showcases how Berkeley Lab's computational resources are essential for fundamental discoveries. An international team with key contributions from Berkeley Lab scientists used the Karlsruhe Tritium Neutrino Experiment (KATRIN) in Germany to establish a new upper limit for the neutrino mass of 0.8 electronvolts (eV), a milestone announced in 20224 .
The experiment makes use of the beta decay of tritium, a radioactive hydrogen isotope. When tritium decays, it releases electrons. The KATRIN team meticulously measured the energy of these electrons with unparalleled precision using a giant spectrometer. The mass of the neutrino affects the energy distribution of these electrons; by finding the very smallest energy values, scientists can deduce the mass of the neutrino4 .
The data from KATRIN was immense and complex, filled with tiny signals and potential background noise. To extract a reliable result, researchers turned to a sophisticated statistical method called Bayesian analysis. This technique is incredibly computationally intensive, requiring the massive processing power of the Cori supercomputer at NERSC4 .
The Bayesian analysis, powered by NERSC, allowed the team to assign probabilities to different neutrino mass values with unprecedented confidence. The finding of 0.8 eV—the first time a direct neutrino mass experiment entered the sub-eV range—was a landmark achievement. It provided a tighter constraint for cosmological models and pushed the frontiers of our understanding of the fundamental building blocks of the universe4 .
