NEW YORK (GenomeWeb) – By modifying the methods and analytical approaches it used, a team of researchers was able to sequence 26 marine microbial genomes and two marine metagenomes while on a research vessel in the Pacific Ocean.

The researchers had previously traveled to the Southern Line Islands, a set of islands in the central Pacific, to study the coral reef there and how the organisms that inhabit it compete for resources. They were, though, stymied by having to collect samples and return to San Diego to analyze them and come up with new hypotheses to test.

In PNAS this week: genomic study of group B Streptococcus evolution, selection on the X chromosome in great apes, and more.

Changing the fat and fiber content of people's diets affects their gut microbiome, metabolome, and colon cancer risk, researchers say.

Broken links are found throughout academic publications, and some services are trying to combat such link decay.

Nick Stockton at Wired says that a pause in studying genome-editing tools should be used to find a path forward.
