Scientists have discovered the first molecular evidence that when exposed to environmental stress corals and anemones can optimize their gene expression enabling them to acclimatize to extreme conditions such as those experienced during climate change.
Elderly individuals with fewer teeth, poor dental hygiene, and more cavities constantly ingest more dysbiotic microbiota, which could be harmful to their respiratory health, according to new research published in the journal mSphere. The findings come from a large, population-based study that identified variations in the tongue microbiota among community-dwelling elderly adults in Japan.
Microscopic plant-like organisms called phytoplankton support the diversity of life in the ocean. Scientists in Israel now report that one species, Emiliania huxleyi, and a virus closely associated with it, might be responsible for changes in cloud properties as well. When infected, E. huxleyi releases its chalky shell into the air, where it acts as an aerosol reflecting sunlight and even affecting cloud creation and movement. The research appears Aug. 15 in the journal iScience.
UC San Diego biologists and their colleagues have revealed that enhancer RNAs play a significant role in cancer dissemination. The researchers found that eRNAs have a direct role in the activation of genes that are important for tumor development. This role is facilitated by the ability of eRNAs to directly interact with BRD4, a protein known as a cancer disseminator. BRD4 has been recognized as a promising cancer target.
Researchers comparing clonal strains of the mycobacteria that cause TB, before and after they developed resistance to a first-line drug, found that a single genetic change may not always have identical effects on bacterial fitness.
A University of Oklahoma professor, Jizhong Zhou, and his team have completed a new study on the effects of climate warming on soil microbes in a long-term climate change experiment at a tallgrass prairie ecosystem. The new study shows that climate warming will affect microbial communities in the future, and future community states will be more predictable under warmed climate. Eventually, microbial communities will produce different functions and feedbacks to climate warming.
Chemicals produced by vegetables such as kale, cabbage and broccoli could help to maintain a healthy gut and prevent colon cancer, a new study from the Francis Crick Institute shows.
Reports from cannabis users that the drug reduces the symptoms of inflammatory bowel disease (IBD) may finally be explained by new research from the University of Massachusetts Medical School and the University of Bath showing that endocannabinoids help control and prevent intestinal inflammation in mice.
A new study published in the scientific journal PLOS Computational Biology led by Patrick Bradley, a postdoctoral scholar in Katherine Pollard's laboratory at the Gladstone Institutes, found a new approach to identify the genes that may be important to help microbes live successfully in the human gut.
Algae and corals have been leaning on each other since dinosaurs roamed the earth, much longer than had been previously thought.
