Entanglement unlocks scaling for quantum machine learning

DOE/Los Alamos National Laboratory
Peer-Reviewed Publication

The field of machine learning on quantum computers got a boost from new research removing a potential roadblock to the practical implementation of quantum neural networks.

Sandia scientist to lead materials science organization

DOE/Sandia National Laboratories

Brad Boyce, a materials scientist at Sandia National Laboratories, was elected president of The Minerals, Metals and Materials Society. Boyce will become vice president of the society on March 3 at its annual meeting,

Improved nuclear accident code helps policymakers assess risks from small reactors

DOE/Sandia National Laboratories

Sandia National Laboratories recently updated the Maccs code to better aid the Nuclear Regulatory Commission and the global nuclear industry in assessing the consequences of nuclear accidents. The Maccs code can also evaluate the potential health and environmental risks posed by advanced nuclear reactors and small modular nuclear reactors.

Capturing hidden data for asymptomatic COVID-19 cases provides a better pandemic picture

DOE/Los Alamos National Laboratory
Peer-Reviewed Publication

Asymptomatic COVID-19 cases are the bane of computer modelers’ existences--they throw off the modeling data to an unknown degree. You can’t measure what you can’t detect, right? A new approach from Los Alamos National Laboratory’s Theoretical Division, however, explores using historic epidemic data from eight different countries to estimate the transmission rate and fraction of under-reported cases.

Perovskite research advances offer new possibilities for devices such as solar cells

DOE/Los Alamos National Laboratory

Perovskite materials are low-cost, solution-processable semiconductors that can absorb and convert solar energy with extraordinarily high efficiencies, making them promising material for use in applications such as photovoltaic solar cells – if the material can be made stable and efficient.

Tracking the cells that host HIV

DOE/Los Alamos National Laboratory
Peer-Reviewed Publication

New research sheds light on the lifespans and location of the cells that are responsible for producing HIV, preventing its eradication. Understanding the cells’ dynamics may help scientists develop new ways to reduce their number with the ultimate goal of curing HIV infection.

New polymer fuel cells can operate at higher temperatures

DOE/Los Alamos National Laboratory
Peer-Reviewed Publication

A new high-temperature polymer fuel cell that operates at 80-160 degrees Celsius, with a higher-rated power density than state-of-the-art fuel cells, solves the longstanding problem of overheating, one of the most significant technical barriers to using medium-and heavy-duty fuel cells in transportation vehicles such as trucks and buses.

Major milestone for B61-12 life extension program

DOE/Sandia National Laboratories

Sandia National Laboratories marked a major milestone when the Nuclear Security Enterprise successfully produced the first completely refurbished bomb for the B61-12 life extension program in November 2021. More than 5,000 employees have worked on the B61-12 life extension program at Sandia during the last decade. As part of the program, Sandia worked to refurbish, replace or reuse about 50 different components and sub-systems that make up the B61-12.
