NewsDe-mystifying common misconception about the prevalence of Legionella bacteria
There is a common misconception that Legionella is only found in air conditioners and water towers - however, a new study has found people are likely exposed to the bacteria through other sources, including through soil.

NewsNew antibiotic to fight superbug C. diff proves effective in clinical trial
As the effectiveness of antibiotics meant to fight the deadly superbug Clostridioides difficile wanes, a research team is seeing positive results of a new antibiotic on the scene – ibezapolstat – which is proving successful in fighting these infectious bacteria in clinical trials.

NewsScientists unveil viral mechanism behind nasopharyngeal cancer spread
Researchers have discovered that the Epstein-Barr virus (EBV), a common human virus closely linked to nasopharyngeal carcinoma (NPC), can change the 3D structure of the human genome inside cancer cells, much like assembling building blocks.

NewsA survival kit for smallpox viruses
Scientists have discovered a previously unknown type of assembly chaperone during their analysis of poxviruses, and they have decoded its function in full detail. This is the first known chaperone that is not formed by a protein but by a nucleic acid — specifically RNA.

NewsResearchers map key human proteins that power coronavirus replication, pointing to new treatment strategies
Scientists have pinpointed dozens of human proteins that SARS-CoV-2 needs to complete its full life cycle, from entering a cell to replicating and releasing new viral particles.

NewsIn extensive sequencing study, scientists find few links between cancer and microbiome
Scientists say a study that sequenced human cancers found far less microbial DNA sequences than earlier studies reported in the same cancer tissue samples.

NewsFungi–biochar partnership boosts soil health and crop growth under cadmium stress
A study reports that combining arbuscular mycorrhizal fungi (AMF) with biochar can reshape soil microbiomes, reduce cadmium uptake, and dramatically improve plant growth, offering a sustainable strategy for restoring farmland contaminated with heavy metals.

NewsRoutine Helicobacter pylori screening does not significantly reduce upper gastrointestinal bleeding in patients after a heart attack
Routine Helicobacter pylori screening did not significantly reduce the risk of upper gastrointestinal bleeding in patients hospitalised for myocardial infarction (MI), according to new research.

NewsConnection among gut fungi, genetics and disease risk in humans identified
A novel genome-wide association study sheds light on the human genetic determinants of the fungal component of the human microbiome and their relation to chronic disease.

NewsHeme-based sulfide sensing in bacteria: a new target for antibiotics
Heme binding to a bacterial transcription factor is critical for hydrogen sulfide (H₂S) signaling, a new study reveals. Heme binding promotes the reaction of H₂S with the transcription factor, leading to structural changes that can regulate stress tolerance in bacteria.

NewsFighting extinction, coral reefs show signs of adapting to warming seas
By studying how six months of elevated ocean temperatures would affect a species of coral from the northern Red Sea, scientists found that although these organisms can certainly survive in conditions that mimic future warming trends, they don’t thrive.

NewsGame-changing biotech for engineering pathogen-resistant crops
Researchers have identified an ancient protein that has the potential to help defend plants against tens of thousands of different bacteria and other pathogens. Dubbed “SCORE”, this receptor detects cold-shock protein—variations of which are found in more than 85% of known bacteria, as well as fungi and insects.

NewsBroccoli seeds can spread resistance to multiple fungicides
Researchers who screened commercial broccoli seeds for Alternaria brassicicola, a fungal pathogen, found that seeds can harbor A. brassicicola and can spread resistance to multiple fungicides. Based on the findings, the researchers developed a faster way for detecting and monitoring fungicide resistance.

NewsGray seals perplex scientists with lack of response to flu infection
Something strange happens when two kinds of seals living in the waters around Cape Cod get infected with influenza – harbor seals get sick but gray seals don’t. This perplexing phenomenon led scientists to investigate if a difference in a piece of the immune system called cytokines could be responsible for this difference.

NewsDesert soils emit greenhouse gases in minutes — even without live microbes
A groundbreaking study reveals that desert soils can emit powerful greenhouse gases within minutes of being wetted—even in the absence of microbial life. It challenges long-standing assumptions that soil microbes are solely responsible for post-rain “pulse emissions” of gases like carbon dioxide (CO₂), nitrous oxide (N₂O), and nitric oxide (NO).

NewsDNA analysis shows colorectal cancer has unique microbial fingerprint
Colorectal cancer is unique in having its own microbial ‘fingerprint’ – according to new research that could help doctors better understand how this cancer develops, how aggressive it might be, and even how a patient might respond to treatment.

NewsAre probiotics worth the cost to prevent infection after a colon removal surgery?
A study found that taking an 8-strain probiotic daily may reduce the risk of pouchitis, a common inflammatory condition that occurs after colon removal surgery for ulcerative colitis, but the treatment may not be worth the cost depending on a patient’s likelihood of flare-ups.
-
NewsNew papers reveal how gut-brain interactions shape eating behaviors
Researchers found that stress from life circumstances can disrupt the brain-gut-microbiome balance. This disruption may alter mood, decision-making, and hunger signals — increasing the likelihood of craving and consuming high-calorie foods.

NewsPretreatment methods deploying microbes bring second-gen biofuels from oilcane closer to commercialization
In collaboration with other Bioenergy Research Centers (BRCs), researchers at the Center for Advanced Bioenergy and Bioproducts Innovation (CABBI) are developing industrially feasible techniques for second-generation biofuel production from oilcane, an oil-rich variety of sugarcane, to help meet our growing societal demand for fuels.

NewsAntibody-making cells reveal new function in response to flu infection
A study has uncovered a new function of the immune cells that are known for making antibodies. Researchers determined that, in response to flu infection, a specialized set of B cells produce a key signaling molecule that the immune system needs to develop a robust, long-term response to fight off infections.
