Getting a Big Look at Tiny Particles

At the turn of the 20th century, scientists discovered that atoms were composed of smaller particles. They found that inside each atom, negatively charged electrons orbit a nucleus made of positively charged protons and neutral particles called neutrons. This discovery led to research into atomic nuclei and subatomic particles. An…

Solving A Beta Decay Puzzle

OAK RIDGE, Tenn., March 11, 2019—An international collaboration including scientists at the Department of Energy’s (DOE’s) Oak Ridge National Laboratory (ORNL) solved a 50-year-old puzzle that explains why beta decays of atomic nuclei are slower than what is expected based on the beta decays of free neutrons. The findings, published…

Modeling the Origin Story of the Elements

Written by: Sean M. Simoneau, [email protected], 865.241.0709 More than 1800 years ago, Chinese astronomers puzzled over the sudden appearance of a bright “guest star” in the sky, unaware that they were witnessing the cosmic forge of a supernova, an event repeated countless times scattered across the universe. Today, with more…

New Geometric Model Improves Predictions of Fluid Flow in Rock

Deep beneath the Earth’s surface, oil and groundwater percolate through gaps in rock and other geologic material. Hidden from sight, these critical resources pose a significant challenge for scientists seeking to evaluate the state of such two-phase fluid flows. Fortunately, the combination of supercomputing and synchrotron-based imaging techniques enables more…

ORNL Security Teams Prepare to Take the Heat with Cyber Fire

The high-performance computing (HPC) cybersecurity engineers at the US Department of Energy’s (DOE’s) Oak Ridge National Laboratory (ORNL) typically face small cybersecurity incidents, so they don’t often get a chance to respond to bigger events. Cyber Fire is a program that offers multiple cybersecurity training events to staff members at…
