NewsHow brick-building bacteria react to toxic chemical in Martian soil
Researchers investigated how bacteria that can mould Martian soil into brick-like structures fare in the presence of perchlorate, a toxic chlorine-containing chemical discovered in Martian soil. It slows down bacterial growth - but surprisingly leads to the formation of stronger bricks.

NewsHow bacteria learned to target numerous cell types, revealed
A new study shows how bacteria adapted a virus-derived injection system to recognize and attach to many different types of cells. By identifying thousands of rapidly evolving receptor-binding proteins, the researchers explain how these systems can be retargeted in nature by swapping the part that binds to cells.

NewsGenetic system makes worker cells more resilient producers of nanostructures
Researchers report the development of a new genetic regulatory system to improve cell viability during the production of gas vesicles.

NewsPediatric investigation study reports significant shifts in post-COVID respiratory infection trends in children
To explore how the pandemic changed respiratory infection trends in children, researchers examined data from 73,096 pediatric patients hospitalized with acute respiratory tract infections in two coastal cities in eastern China with similar climates.

NewsOne of Earth’s most abundant organisms is surprisingly fragile
A group of ocean bacteria long considered perfectly adapted to life in nutrient-poor waters may be more vulnerable to environmental change than scientists realized. The bacteria, known as SAR11, dominate surface seawater worldwide and can make up as much as 40% of marine bacterial cells.

NewsNew research finds crosstalk inside cells helps pathogens evade drugs
Biologists have uncovered a new mode of communication inside cells that helps bacterial pathogens learn how to evade drugs. Their findings describe how these mechanisms drive antimicrobial resistance in Listeria monocytogenes, the foodborne bacteria that causes listeriosis.

NewsNatural sunscreen compounds show potential to support skin health and blood pressure
Researchers have discovered that natural ‘sunscreen’ compounds found in algae and cyanobacteria may also support skin and heart health.

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.
