Scientists develop environmental justice lens to identify neighborhoods vulnerable to climate change

A new capability to identify urban neighborhoods, down to the block and building level, that are most vulnerable to climate change could help ensure that mitigation and resilience programs reach the people who need them the most.

Supercomputing, neutrons crack code to uranium compound’s signature vibes

Oak Ridge National Laboratory researchers used the nation’s fastest supercomputer to map the molecular vibrations of an important but little-studied uranium compound produced during the nuclear fuel cycle for results that could lead to a cleaner, safer world.

COVID — Changing behavior

Researchers at Oak Ridge National Laboratory have empirically quantified the shifts in routine daytime activities, such as getting a morning coffee or takeaway dinner, following safer at home orders during the early days of the COVID-19 pandemic. These insights, published in the Journal of Transport Geography, could help officials better understand traffic patterns and supplement the response to emergencies or crises. 

Physics — Cosmic collisions revealed

Scientists are using Oak Ridge National Laboratory’s Multicharged Ion Research Facility to simulate the cosmic origin of X-ray emissions resulting when highly charged ions collide with neutral atoms and molecules, such as helium and gaseous hydrogen.

“This facility gives us a new X-ray observational window to peer into otherwise invisible processes found in star-forming galaxies, galaxy clusters, supernova remnants and relativistic jets from black holes,” said ORNL’s Charles Havener.
