Climate Change Threatens Base of Polar Oceans’ Bountiful Food Webs
A study recently published in Nature Communications suggests that displacing cold-water communities of algae with warm-adapted ones threatens to destabilize the delicate marine food web. The team was led by University of East Anglia researchers and included DOE Joint Genome Institute researchers.
The Hidden Reason Children Born by C-Section Are More Likely to Develop Asthma
Researchers at Rutgers University, the Copenhagen Prospective Studies on Asthma in Childhood and the University of Copenhagen have described for the first time how delivery by caesarean section interferes with a baby’s ability to obtain beneficial germs from the mother’s microbiome, and how this can lead to early childhood asthma.
Uncovering Novel Genomes from Earth’s Microbiomes
Reported in Nature Biotechnology, the known diversity of bacteria and archaea has been expanded by 44% through a publicly available collection of more than 52,000 microbial genomes from environmental samples resulting from a JGI-led collaboration involving more than 200 scientists around the world.
The Parkinson’s disease gut has an overabundance of opportunistic pathogens
A 2003 hypothesis says Parkinson’s disease is caused by a gut pathogen that could spread to the brain through the nervous system. No evidence was found until now; researchers report for the first time a significant overabundance of a cluster of opportunistic pathogens in the PD gut.
Individualized mosaics of microbial strains transfer from the maternal to the infant gut
A microbiome “fingerprint” method shows that an individualized mosaic of microbial strains is transmitted to the infant gut microbiome from a mother giving vaginal birth. The study analyzed existing metagenomic databases of fecal samples from mother-infant pairs and used a germfree mouse model.
