Genes that make bacteria resistant to antibiotics are much more widespread in our environment than was previously realised.
Microbes are by far the most important factor in determining how much carbon is stored in the soil, according to a new study with implications for mitigating climate change and improving soil health for agriculture and food production.
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.
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.
Scientists at McMaster University and the Massachusetts Institute of Technology have used artificial intelligence to discover a new antibiotic which could be used to fight a deadly, drug-resistant pathogen that strikes vulnerable hospital patients.
A new tool which could help reduce the spread of antimicrobial resistance is showing early promise, through exploiting a bacterial immune system as a gene editing tool.

Finding, cultivating, and bioengineering organisms that can digest plastic not only aids in the removal of pollution, but is now also big business.
In a new study, researchers use cheese rinds to demonstrate that fungal antibiotics can influence how microbiomes develop.
Columbia synthetic biologists have developed a new method that uses engineered bacteria and AI to sense and record environmental signals. They are the first to engineer bacterial swarm patterns to visibly record their environment and use deep learning to decode patterns. This work could lead to applications ranging from monitoring environmental pollution to building living materials.
Many people have experienced infections from E. coli, which are primarily seen as inconvenient and unpleasant. For some patients, like those with blood cancer, however, there is a risk that the bacteria will travel into the bloodstream.
Common food additives known as metal oxide nanoparticles may have negative effects on your gut health, according to new research from Binghamton University, State University of New York and Cornell University.
The roles microbes play in ecosystems are changing with global warming. Microbes are also affected by infection by viruses, but scientists know relatively little about how these viral infections could change how microbes react to warming. In this study, scientists describe different ways that increasing temperatures could affect viruses and their microbial hosts. Their preliminary models show that viruses could alter carbon balance, causing some ecosystems to switch from net carbon sources to net carbon sinks.
The National Academy of Sciences (NAS) has announced that Claire M. Fraser, PhD, the Dean E. Albert Reece Endowed Professor in the Department of Medicine at the University of Maryland School of Medicine (UMSOM), and the Founding Director of the Institute for Genome Sciences (IGS), has been elected as a new member of the prestigious academy.
The researcher discusses the findings in a new study on the efficacy and safety of fecal microbiota (REBYOTA™), the first microbiota-based live biotherapeutic approved by the US FDA used to prevent recurrent Clostridioides difficile infection in adults.
Researchers from Brazil showed that Amazonian dark earth (ADE), soils enriched by Amerindian people thousands of years ago, increases the establishment and growth of seedlings of tree species important for reforestation. By copying the composition of ADE, especially its microbes, reforestation in Brazil and elsewhere could be sped up
We know that eating a healthy diet affects body weight, cholesterol levels, and heart health. A new study from the University of Illinois focuses on another component: the role of diet in supporting a healthy gastrointestinal microbiota. The researchers conclude that following the Dietary Guidelines for Americans (DGA) promotes a gut microbiota composition that may support overall health.
REBYOTA is indicated for the prevention of recurrence of Clostridioides difficile (C. diff) infection in individuals 18 years of age and older, following antibiotic treatment for recurrent C. diff infection.
Digestive Disease Week (DDW) is the largest international gathering of physicians, researchers, and academics in the fields of gastroenterology, hepatology, endoscopy, and gastrointestinal surgery. DDW2023 will take place May 6-9 in Chicago and showcase 3,100 abstracts and hundreds of lectures on the latest advances in GI research, clinical practice and technology.
Researchers at Umeå University, Sweden, have found that among the many factors that shape the intestinal microbiota composition, diet has a much stronger impact than defensins, which are intestinal defence molecules produced by the body.
A new study from Washington University School of Medicine in St. Louis suggests that some dangerous bloodstream infections in premature infants may be caused by strains of bacteria already lurking in their gut microbiomes.
For millions of Americans that suffer from seasonal allergies (pollen and mold), climate change is exacerbating an earlier, longer, and overall worse allergy season.
There are no plants, and only very few animals: people rarely come here. The large glaciers in Greenland have long been perceived as ice deserts. Gigantic ice sheets where conditions for life are extremely harsh.
The prestigious J. Roger Porter Award has been awarded to Kevin McCluskey in recognition of his outstanding work in support of microbial culture collections when he was curator of the Fungal Genetic Stock Center (FGSC)

Colistin is a last-resort antibiotic critical for treating multidrug-resistant bacterial infections. Resistance to colistin heralds the emergence of truly pan-resistant infections. In the article, the researchers found combining colistin with inhibitors of biotin (vitamin B7) or fatty acid production can overcome colistin resistance.
Increasing temperature or nutrients in an ecosystem can destabilize food webs, but when temperature and nutrients increase together it can be difficult to predict the combined effects. This study examined a laboratory microbial food web consisting of bacterial prey and protist predators. It found that temperature and nutrients can alter the dynamics of microbial communities by changing how species’ abundances and average body sizes relate to each other.
The cells of living organisms are equipped with proteins that are involved in the shaping and remodeling of cellular membranes, thereby performing important tasks.

Researchers at UT Southwestern Medical Center have discovered how a bacterium that infects people after they eat raw or undercooked shellfish creates syringe-like structures to inject its toxins into intestinal cells. The findings, published in Nature Communications, could lead to new ways to treat food poisoning caused by Vibrio parahaemolyticus.
Scientists at the University of California, Irvine have made a remarkable discovery about cellophane bees – their microbiomes are some of the most fermentative known from the insect world. These bees, which are named for their use of cellophane-like materials to line their subterranean nests, are known for their fascinating behaviors and their important ecological roles as pollinators.
