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.

Sandia mechanical engineer Michael Omana was named a 2021 Most Promising Scientist, Masters at the conference.

New experiment results bolster potential for self-sustaining fusion

DOE/Los Alamos National Laboratory
Peer-Reviewed Publication

For more than 60 years, scientists have sought to understand and control the process of fusion, a quest to harness the vast amounts of energy released when nuclei in fuel come together. A paper published today in the journal Nature describes recent experiments that have achieved a burning plasma state in fusion, helping steer fusion research closer than it has ever been to its ultimate goal: a self-sustaining, controlled reaction.

2021 AAAS fellows announced

DOE/Los Alamos National Laboratory
Grant and Award Announcement

Three Los Alamos scientists have been named fellows of the American Association for the Advancement of Science (AAAS). Election to AAAS fellowship is an honor bestowed upon AAAS members by their peers for their scientifically or socially distinguished efforts to advance science or its applications.

Powerful Sandia machine-learning model shows diamond melting at high pressure

DOE/Sandia National Laboratories
Peer-Reviewed Publication

Is there no backbone left in the world? Even diamond - the hardest material on Earth - melts when subjected to enough pressure. To learn why, and who or what may be next, read the article on the SNAP simulation model below.
