NewsGut bacteria may tip the balance between feeding tumors and fueling immunity
A new study reveals how bacteria in the gut can help determine whether the amino acid asparagine from the diet will feed tumor growth or activate immune cells against the cancer.

NewsDissolved bubble microneedles enable more efficient therapy of acne vulgaris
Researchers report a new microneedle-based strategy for acne therapy in a new study. The team developed dissolved bubble microneedle patches that can simultaneously deliver hydrophilic and hydrophobic drugs directly into acne-affected skin.

NewsSepsis study IDs simple ways to save lives in Africa
Tuberculosis (TB) is a major unrecognized cause of deadly sepsis among people with HIV in Africa, a new study reveals. It found that more than half of the hundreds of patients enrolled in the study had TB and that immediate treatment increased their chances of survival significantly.

NewsFrom biocidal coatings to medicines: A nanocomposite sting for microorganisms
A surface capable of responding to chemical signals generated by microorganisms and automatically producing biocidal substances – a description of how the B-STING silica nanocomposite works. The new material acts as a nanofactory of reactive oxygen species, activating only when necessary.

NewsRethinking global AMR strategy: the 2024 WHO Bacterial Priority Pathogens List from a One Health perspective
A new perspective examines the World Health Organization’s 2024 Bacterial Priority Pathogens List (WHO BPPL), highlighting its strengths as a research roadmap while identifying critical gaps for a truly holistic antimicrobial resistance (AMR) strategy.

NewsGlowing bacterial sensors detect gut illness in mice before symptoms emerge
Researchers have engineered gut bacteria that dim their fluorescent glow in the presence of illness. Their findings could improve how we diagnose problems in the gut by using bacteria that already live there.

NewsHow genes influence the microbes in our mouths
A new study has found human genetic factors that influence the oral microbiome and may increase risk of cavities and tooth loss in some people. Analysis of the now largest collection of oral microbiome profiles reveals interactions between human and bacterial DNA.

NewsSerum interleukin-8 can tell pulmonary aspergillosis from bacterial pneumonia in patients with liver failure
Scientists found serum interleukin-8 can be used to differentiate invasive pulmonary aspergillosis from bacterial pneumonia in patients with HBV-associated acute-on-chronic liver failure.

NewsWild blueberries: New review explores benefits for heart, metabolism and the microbiome
A new scientific review summarizes the growing body of research on wild blueberries and cardiometabolic health, which includes factors like blood vessel function, blood pressure, blood lipids and blood sugar. It highlights the gut microbiome as a likely contributor to the cardiometabolic effects.

NewsResearchers discover a previously unknown bacterial component in kidney stone formation
In an unexpected finding, scientists have discovered that bacteria are present inside the most common type of kidney stone, revealing a previously unrecognized component involved in their formation. The findings point to a possible therapeutic target that could be used for prevention and treatment.

NewsEarly warning for wine spoilage glows in the dark
Researchers have built a living biosensor made of bacteria that lights up when it detects acetic acid, the main chemical signal that wine is starting to spoil. It works in real time, even in high-alcohol conditions, so wineries can catch problems early, before flavor and quality are damaged.

NewsMore than just gut cohabitants: how gut bacteria control immune responses
Bacteria in the human gut can directly deliver proteins into human cells, actively shaping immune responses. The study reveals a new way in which the gut microbiome can influence the human body and may help explain how changes in gut bacteria contribute to inflammatory diseases.

News3′UTR-derived small RNA couples acid resistance to metabolic reprogramming in Salmonella within macrophages
Salmonella expresses the arginine decarboxylase AdiA, which confers acid resistance by catalyzing an H+-consuming reaction. Researchers have discovered that the 3′-untranslated region (UTR) of adiA mRNA is processed by RNase E into a regulatory small RNA, AdiZ.

NewsMore investigations needed into Wumei Pills-Lactobacillus Reuteri-intestinal stem cell axis for chemotherapy-Induced mucositis
A new letter appraising a recent study suggests the reported benefits of WMP and Lactobacillus reuteri in chemotherapy-induced mucositis are promising, but stronger causal and analytical foundations are needed.

NewsAncient DNA pushes back record of treponemal disease-causing bacteria by 3,000 years
Scientists have recovered a genome of Treponema pallidum from 5,500-year-old human remains in Sabana de Bogotá, Colombia. The research expands knowledge about the history of this infectious disease and its occurrence in human populations.

NewsResurrected ancient enzyme offers new window into early Earth and the search for life beyond it
By resurrecting a 3.2-billion-year-old enzyme and studying it inside living microbes, researchers have created a new way to improve our understanding of the origins of life on Earth. The study uses synthetic biology to reverse-engineer modern enzymes and rebuild their possible ancestors.

News‘Trojan horse’ may deliver toxic dose of copper to bacterial colonies, including drug-resistant MRSA infections
A research team is developing a drug that works in combination with copper to kill bacteria, including those that cause MRSA, a type of staph infection that is resistant to usual treatments.

NewsHow a single gene shapes gut health and IBD risk
Two recent studies highlight the role of a gene called PTPN2 in protecting the gut from harmful bacteria linked to inflammatory bowel disease (IBD). When PTPN2 does not function properly, the gut becomes more vulnerable to infection and inflammation.
