Scientists encased nanodiamonds in tiny moving droplets of water to improve quantum sensing. The new technique lets researchers detect trace amounts of certain ions and molecules, and could someday find applications in environmental monitoring, medicine, bioengineering, and more.

Aindrila Mukhopadhyay has been elected to the American Academy of Microbiology fellows in recognition of her achievements in functional genomics and systems biology.
Plants Use Signaling Molecules to Fine-tune Their Microbiomes
Researchers have identified several key compounds that shape the microbial communities dwelling around plant roots and soil, opening up the possibility for agricultural strategies that precisely and sustainably improve plant health and crop yields. One such compound was serotonin, a signaling molecule commonly known for its role in mood regulation. In this context, serotonin was found to enhance plant growth and shape microbial communities living around plant roots under nutrient-rich conditions.
Taking Stock of the Known and Unknown Microbial Space
In Science Advances, JGI researchers have taken stock of the current state of microbial genomic biodiversity. Using publicly available genome sequence data generated over the past three decades, their study assesses what fraction of the microbial diversity we know about, and proposes a path forward to curate and cultivate what is still unknown.
Unraveling the Mysteries of DNA Damage in the Brain
A first-of-its-kind study led by Cynthia McMurray and Aris Polyzos in the Molecular Biophysics and Integrated Bioimaging (MBIB) Division integrated cell type– and brain region–specific features of DNA repair in normal brains, setting a benchmark for the field. Their results, recently published in Nature Communications, suggest that DNA damage itself serves as the checkpoint, limiting the accumulation of genomic errors in cells during natural aging.
