To study microbes, scientists need to collect, process, and share data in a standardized way. The National Microbiome Data Collaborative (NMDC) Ambassador Program launched in 2021 to increase awareness and adoption of microbiome metadata standards. During the program’s year-long term in 2021 and 2022, more than 800 researchers attended 23 Ambassador-hosted presentations.

Altered gut bacteria may be early sign of Alzheimer’s disease
Washington University in St. Louis

Alzheimer’s disease causes changes to the brain that begin two decades or more before symptoms appear. A study by researchers at Washington University School of Medicine in St. Louis reveals that the bacteria that live in the gut also change before Alzheimer’s symptoms arise, a discovery that could lead to diagnostics or treatments for Alzheimer’s disease that target the gut microbiome.

Technique Restores Healthy Bacterial Balance in C-Section Babies
Rutgers University-New Brunswick

Newborns delivered by cesarean section who are swabbed with the vaginal fluid of their mothers after birth have beneficial bacteria restored to their skin surface and stools, according to a new study. In the first randomized study of its kind, published in the science journal mBio, a team of researchers found the process, known as vaginal seeding, definitively engrafted new strains of maternal bacteria in the babies’ bodies.

UW Medicine launches a new center to study microbiomes
University of Washington School of Medicine and UW Medicine

Director Joseph Mougous notes that interbacterial interactions affect humans in many ways, such as whether certain pathogens succeed in invading the gastrointestinal tract. Mougous has published findings about the bacterial battles that occur even amongst the beneficial microbes in our gut, where the outcome can ultimately also influence health.

Machine Learning-Based Protein Annotation Tool Predicts Protein Function
Department of Energy, Office of Science

Microbes drive key processes of life on Earth. Research constantly expands the database of microbial DNA sequences but does not provide full biological information about proteins. To engineer microbes, scientists need a fuller understanding of protein function. Scientists currently infer protein function by comparing it with reference databases, but this process is slow. To address this challenge, scientists developed Snekmer, a machine learning-based tool for modeling protein function.

CHOP Researchers Show that IgA Fine Tunes the Body’s Interactions with Microbes
Children's Hospital of Philadelphia

A new study by researchers at Children’s Hospital of Philadelphia (CHOP) has demonstrated that IgA acts as a “tuner” that regulates the number of microbes the body sees every day, restraining the systemic immune response to these commensal microbes and limiting the development of systemic immune dysregulation.
