Lab team studies calibrated AI and deep learning models to more reliably diagnose and treat disease

May 29, 2020- 
As artificial intelligence (AI) becomes increasingly used for critical applications such as diagnosing and treating diseases, predictions and results regarding medical care that practitioners and patients can trust will require more reliable deep learning models. In a recent preprint (available through Cornell University’s open access website arXiv), a team led by a Lawrence Livermore...

Lab activities increase, but remote work will continue

May 28, 2020- 
Since I spoke to you during my virtual all hands meeting, activity at the Laboratory has continued to increase, with approximately 25 percent of the Lab’s workforce now on site to support work prioritized by the National Nuclear Security Administration (NNSA), as well as some non-NNSA work supported by other sponsors. The scope of these efforts puts us in a new posture defined by NNSA as...

Simulations explain detonation properties in TATB

May 26, 2020- 
Two Lawrence Livermore National Laboratory (LLNL) scientists have discovered a new mechanism for ignition of high explosives that explains the unusual detonation properties of 1,3,5-triamino-2,4,6-trinitrobenzene (TATB). The research will allow for systematic improvements to continuum mechanics models used to assess the performance and safety of the material accurately and reliably. Hi...

Lab provides assistance in national swab shortage

May 21, 2020- 
In this era of COVID-19, tracking the disease adequately enough to allow state and local officials to lift shelter-in-place orders and return to a semblance of normalcy in the absence of a vaccine will require widespread testing, according to medical experts. However, such extensive testing efforts have been hampered due to a shortage of nasopharyngeal (NP) swabs, the preferred tool used by...

Membrane nanopore transport gets picky

May 20, 2020- 
Trying to determine how negatively charged ions squeeze through a carbon nanotube 20,000 times smaller than a human hair is no easy feat. Not only did Lawrence Livermore National Laboratory (LLNL) scientists do that but they found that those ions are unexpectedly picky depending on the anion (a negatively charged ion). The research appears in ACS Nano. Inner pores of carbon nanotubes...

COVID-19 research goes public through new portal
