Fresh insights into how our bodies interact with the microbes living in our guts suggest that a two-drug combination may offer a new way to treat inflammatory bowel diseases such as Crohn’s disease and ulcerative colitis.
The dynamics and availability of soil nutrients affects the growth of plants and microbes and how ecosystems respond to changing environmental conditions. Researchers investigated climate impacts on peat nutrient availability as part of the large-scale Spruce and Peatland Responses Under Changing Environments (SPRUCE). The experiment found that above- and below-ground warming exponentially increased the availability of nutrients throughout below-ground peat layers. However, elevated carbon dioxide did not affect the availability of nutrients.
The findings, published in Nature Microbiology, are particularly important in understanding how and why bacterial communities defer duties to certain cells – and could lead to new ways to tackle antibiotic tolerance further down the line.
Twenty to 50 per cent of all critically ill patients contract potentially deadly infections during their stay in the intensive care unit or in hospital after being in the ICU – markedly increasing the risk of death.

In experiments with mice and humans, a team led by Johns Hopkins Medicine researchers says it has identified a particular intestinal immune cell that impacts the gut microbiome, which in turn may affect brain functions linked to stress-induced disorders such as depression.
Staphylococcus aureus, Clostridioides difficile, Candida auris, Drug-resistant Shigella. These bacteria not only have difficult names to pronounce, but they are also difficult to fight off. These bacteria may infect humans and animals, and the infections they cause are harder to treat than those caused by non-resistant bacteria. Antimicrobial resistance is an urgent global public health threat.
Omnitrophota are nano-sized bacteria first discovered 25 years ago. Though common in many environments around the world, until now they've been poorly understood. An international research team produced the first large-scale analysis of Omnitrophota genomes, uncovering new details about their biology and behavior. The team’s findings are reported in the March 16 issue of the journal Nature Microbiology.
Scientists at the Department of Energy’s Oak Ridge National Laboratory have confirmed that bacteria-killing viruses called bacteriophages deploy a sneaky tactic when targeting their hosts: They use a standard genetic code when invading bacteria, then switch to an alternate code at later stages of infection.
It's sleep awareness week, according to the National Sleep Foundation. It’s important to understand how sleep deprivation can impact your health. Most people recognize that if they don’t get enough sleep, their mood and memory will suffer the next day.
In decades past, scientists have been unable to conclusively identify human-associated microbes in samples collected above 26,000 feet. This study marks the first time that next-generation gene sequencing technology has been used to analyze soil from such a high elevation on Mount Everest, enabling researchers to gain new insight into almost everything and anything that’s in them.
The gut is home to a cast of microbes that influence health and disease. Some types of microorganisms are thought to contribute to the development of inflammatory conditions, such as inflammatory bowel disease (IBD), but the exact cascade of events that leads from microbes to immune cells to disease remains mysterious.
The human intestine is an environment inhabited by many bacteria and other microorganisms collectively known as the gut microbiome, gut microbiota or intestinal flora.
Certain enzymes within a class known as bile salt hydrolases (BSHs) can restrict Clostridioides difficile (C. diff.) colonization by both altering existing bile acids and by creating a new class of bile acids within the gut’s microbial environment. The work could lead to “designer” probiotics that protect against disease.
In a new study published in Nature Medicine, Moffitt Cancer Center physician-scientists, in collaboration with four cancer centers in the United States and Germany, reveal how microorganisms in the gut influence non-Hodgkin lymphoma patient outcomes to a type of cellular immunotherapy called chimeric antigen receptor T-cell therapy, or CAR T.
The paper ‘Weaponising microbes for peace’ by Anand et al, outlines the ways in which microbes and microbial technologies can be used to tackle global and local challenges that could otherwise lead to conflict, but warns that these resources have been severely underexploited to date.
Scientists previously believed that microorganisms could not use pyrite to grow in oxygen-free conditions. New research shows that certain single-celled microorganisms can dissolve pyrite in the absence of oxygen. These microorganisms mine iron and sulfur from the pyrite to build biocatalysts needed for growth. The results have potential applications in biotechnology.
Researchers at UT Southwestern Medical Center have discovered how healthy bacteria can escape the intestine, travel to lymph nodes and cancerous tumors elsewhere in the body, and boost the effectiveness of certain immunotherapy drugs. The findings, published in Science Immunology, shed light on why antibiotics can weaken the effect of immunotherapies and could lead to new cancer treatments.
Plants convert light into a form of energy that they can use – a molecule called adenosine triphosphate (ATP) – through photosynthesis. This is a complex process that also produces sugar, which the plant can use for energy later, and oxygen.

Research in mice shows bacteria hijack communication between nerve and immune cells in the meninges — the protective layers that shield the brain from infection.
In APL Bioengineering, researchers describe how gut-on-a-chip devices can bridge lab models and human biology. Modeling the microbiome is particularly difficult because of its unique environmental conditions, but through creative design, gut-on-a-chip devices can simulate many of these properties, such as the gut’s anaerobic atmosphere, fluid flow, and pulses of contraction/relaxation. Growing intestinal cells in this environment means that they more closely resemble human biology compared to standard laboratory cell cultures.
