Neutrons produce first direct 3D maps of water during cell membrane fusion

DOE/Oak Ridge National Laboratory
Peer-Reviewed Publication

New 3D maps of water distribution during cellular membrane fusion are accelerating scientific understanding of cell development, which could lead to new treatments for diseases associated with cell fusion. Using neutron diffraction at the Department of Energy's Oak Ridge National Laboratory, researchers have made the first direct observations of water in lipid bilayers used to model cell membrane fusion.

Chemists demonstrate sustainable approach to carbon dioxide capture from air

DOE/Oak Ridge National Laboratory

Chemists at the Department of Energy's Oak Ridge National Laboratory have demonstrated a practical, energy-efficient method of capturing carbon dioxide (CO2) directly from air. They report their findings in Nature Energy. If deployed at large scale and coupled to geologic storage, the technique may bolster the portfolio of responses to global climate change.

ORNL-developed technology streamlines computational science projects

DOE/Oak Ridge National Laboratory
Peer-Reviewed Publication

An ORNL research team led by Jay Jay Billings has continuously updated a workflow management system they first developed in 2010 to help computational scientists develop software, visualize data, and solve problems, saving time and effort expended in support of modeling and simulation experiments. Recently, the team published an article inSoftwareX that both details the history of the system and previews the potential benefits of upcoming versions.

Cannibalistic materials feed on themselves to grow new nanostructures

DOE/Oak Ridge National Laboratory
Peer-Reviewed Publication

Scientists at the Department of Energy's Oak Ridge National Laboratory induced a two-dimensional material to cannibalize itself for atomic 'building blocks' from which stable structures formed. The findings, reported in Nature Communications, provide insights that may improve design of 2-D materials for fast-charging energy-storage and electronic devices.

ORNL researchers enable real-time forensic analysis with new cybersecurity tool

DOE/Oak Ridge National Laboratory
Business Announcement

Researchers at ORNL have developed a new cybersecurity tool called Akatosh that automates the process of analyzing computer networks to detect malware. The tool collects historical information on host systems on the network to immediately show changes that transpired leading up to and during a cyber attack, which saves precious time and resources previously spent manually searching the network for changes.
