On April 29, 2021, Berkeley Lab hosted a second workshop to identify the most pressing barriers to wider adoption of single-cell sequencing and omics technologies, and to discuss solutions to remedy those barriers in order to drive discovery. The workshop report is now available for download.
Congratulations to Biosciences Area Director’s Award Recipients
Numerous Biosciences Area personnel are among the 2021 Berkeley Lab Director’s Awards honorees. This annual program recognizes outstanding contributions by employees to all facets of Lab activities. A complete list of winners can be found here. The 10th annual Director’s Awards ceremony will take place on November 18 at noon.
The Paradox of ‘Ultraconserved’ Enhancers: Perfect Sequence Conservation Not Required
The last common ancestor of humans and rodents lived more than 80 million years ago, and billions of changes in their respective DNA sequences have occurred over this vast timespan. Yet, intriguingly, there are a few hundred stretches of DNA in our genome that are still identical to the corresponding sequences in mice and rats. Generally, sequence conservation between distantly related species is an indication that the function the DNA serves is vitally important and highly sensitive to mutations. For example, most DNA sequences that encode proteins show at least moderate conservation in evolution. However, more than two-thirds of the “ultraconserved” sequences shared by humans and rodents are outside of protein-coding genes, raising the question of what led to their extreme level of conservation.
JGI Leads Large-Scale Effort to Develop a Genomic Catalog of Earth’s Microbiomes
Microorganisms play key roles in regulating global nutrient cycles but only a small fraction has been identified and an even smaller number has been successfully cultured in a lab for study. In Nature Biotechnology, the known diversity of bacteria and archaea has now expanded by 44% through a publicly available collection of more than 52,000 microbial genomes from environmental samples. Of that number, 70% of the novel genome sequences were previously unknown, not yet cultured in the lab. The work results from a JGI-led collaboration involving more than 200 scientists around the world, KBase and NERSC. Read more about the genomic catalog of Earth’s microbiomes on the JGI website.
Plant Single-cell Solutions for Energy and the Environment Workshop Report Released
On January 23, 2020, Berkeley Lab hosted a workshop on opportunities afforded by single-cell technologies for energy and environmental science, as well as conceptual and technological grand challenges that must be tackled to apply these powerful approaches to plants, fungi and algae. This event, which was spearheaded by Diane Dickel in the Environmental Genomics and Systems Biology Division, brought together a diverse group of leaders in functional genomics technologies from academia, the National Laboratories, and local research institutions.
