Software improves the speed of identifying potential new antibiotics
Computational biologists at Carnegie Mellon University and seven other institutions developed a software tool that can play a high-speed "Match Game" to identify bioactive molecules and microbial genes that produce them so they can be evaluated as new antibiotics and other therapeutic agents. This work was published in Cell Systems on October 16.  Discuss
Scientists elucidate the genetic impact of host immune system on the microbiome
Researchers at the University of Chicago conducted research that suggests that the genetic differences in the immune system contribute to bacterial colonization of gut. The findings, published in Cell Reports on October 15, uses a new approach to determine the genetic influence of the immune system on the microbiome of mice.  Discuss
DNA Metabarcoding used to analyze human diet
A collaborative study from US researchers demonstrates that DNA metabarcoding has promise for characterization of human diets. The research, which was published in mSystems on October 8, provides evidence that DNA sequencing-based approaches can be successfully applied to human samples.  Discuss
Bacteria use 'poisoned arrowheads' to defeat competition, similar to antibiotics
According to a new study published in Cell Reports on October 1, bacteria use weapons to vanquish their competitors. Researchers at Imperial College London have uncovered a novel weapon that bacteria employ which has a similar mechanism of action as common antibiotics.  Discuss
Form-switching bacteria may cause antibiotic resistance
For the first time, scientists have confirmed that bacteria can change forms to avoid being targeted by antibiotics in the human body. Researchers from Newcastle University used state-of-the-art technology to identify bacteria with this unique characteristic. They show, in a study published in Nature Communications on September 26, that these bacteria can survive without a cell wall, potentially leading to antibiotic resistance.  Discuss
Genomic and microbial analyses reveal microbe independently degrades oil to gas
Methanoliparia, an archaea found in deep within oil reservoirs, may degrade oil to methane all by itself. Researchers from the Max Planck Institute for Marine Microbiology in Bremen, Germany and the MARUM, Centre for Marine Environmental Sciences provide genomic and microbial evidence of Methanoliparia’s ability to transform long-chain hydrocarbons to methane. The results were published in mBio on August, 20.  Discuss
Large-scale analysis of microbiome reveals new classes of small proteins with implications in drug discovery
Trillion of bacteria reside within our bodies, and scientists are just scratching the surface of understanding the microbiome. Researchers at Stanford School of Medicine have shed light on previously unidentified proteins that may have an important role in human health and advance drug development.  Discuss
Finding the next generation of antibiotics may require the use of NGS sequencing and genome mining
Determining how antibiotic structures are formed in nature is crucial knowledge that scientists will leverage in the development of the next generation of antibiotics. Researchers from Washington University in St. Louis and the University at Buffalo published the X-ray crystal structure of an enzyme that produces a candidate antibiotic in Nature Communications on July 31, 2019.  Discuss
Profiling of gut microbiome now possible with new 3D printed pill
Researchers at Tufts University have designed an ingestible, biocompatible, battery-less, 3D-printed micro-engineered pill that will enable them to non-invasively profile bacterial species that could provide new insights into many gastrointestinal diseases.  Discuss
The European Commission pursues open science and why it’s important
Scientists believe that there is a reproducibility crisis in the scientific community where many scientists fail to reproduce experiments, according to a new report by Science | Business in July 2019. Open science is a high priority for the European Commission, with around 70% of all data generated by EU-funded programs being accessible to the public.  Discuss
