Cybersecurity – Put to the test

Oak Ridge National Laboratory researchers have created a technology that more realistically emulates user activities to improve cyber testbeds and ultimately prevent cyberattacks.

The Data Driven User Emulation, or D2U, uniquely uses machine learning to simulate actual users’ actions in a network and then enhances cyber analysts’ ability to thwart, expose and mitigate network vulnerabilities.


Energy Secretary Granholm visits ORNL in virtual tour of world-class science facilities

On Sept. 28, U.S. Secretary of Energy Jennifer Granholm joined leadership and top scientists and engineers online at Oak Ridge National Laboratory for a two-hour whirlwind tour. At 14 stops, researchers highlighted the lab’s world-class facilities and projects that enable leading-edge scientific discoveries and innovations that address some of the nation’s most compelling scientific and technical challenges.


Correlated electrons ‘tango’ in a perovskite oxide at the extreme quantum limit

A team led by the Department of Energy’s Oak Ridge National Laboratory has found a rare quantum material in which electrons move in coordinated ways, essentially “dancing.” Straining the material creates an electronic band structure that sets the stage for exotic, more tightly correlated behavior – akin to tangoing – among Dirac electrons, which are especially mobile electric charge carriers that may someday enable faster transistors. The results are published in the journal Science Advances.

Deeksha Rastogi: Modeling climate extremes for community impact

An international problem like climate change needs solutions that cross boundaries, both on maps and among disciplines. Oak Ridge National Laboratory computational scientist Deeksha Rastogi embodies that approach. She partners with colleagues in many fields, using high-performance computing to understand the human impacts of climate change.
