NewsOne-fifth of pregnant women aren’t properly screened for syphilis
A new study found that 1 in 5 pregnant women in Ontario did not receive timely syphilis screening, which is critical for preventing syphilis infection in newborns. Sociodemographic and behavioural risk factors associated with being screened late may be related to an increased likelihood of inadequate prenatal care access.

NewsParaprobiotic counteracts damage to male fertility from BPA in plastic
BPA has been shown to impair sperm function, in part through increased generation of reactive oxygen species. Researchers investigated whether a paraprobiotic material derived from the lactic acid bacterium Enterococcus faecalis (known as FK‑23) protects against the sperm toxicity caused by BPA.

NewsTargeted therapeutics show promise in fighting off drug-resistant bacteria
A new study shows that when under attack, the body’s immune cells activate a cellular process called ‘mitochondrial fission’ to kill invading bacteria. Researchers found an experimental treatment called an HDAC6 inhibitor can re-activate the mitochondrial fission process in immune cells to fight invading bacteria.

NewsFarming with fish: A natural boost for soil phosphorus
Researchers have uncovered new evidence that rice fish coculture can improve soil nutrient cycling—particularly P—without relying on fertilizers. This reveals that introducing fish into rice paddies enhances the composition and function of phoD-harboring bacteria, which are known to facilitate P mineralization.

NewsAI and supercomputer simulations reveal how a bacterial energy-converting enzyme pumps sodium ions
The Na+-NQR enzyme is vital for energy production in pathogenic bacteria, making it a highly promising target for new antibiotics. Researchers combined modified artificial intelligence techniques with extensive supercomputer simulations to visualize the hidden, dynamic movements of this enzyme during sodium transport.

NewsUnderstanding and exploiting tuberculosis superspreading
A new perspective piece introduces the idea of “superspreading niches”, specific parts of community contact networks where highly infectious individuals intersect with highly susceptible contacts, as a key framework for understanding TB superspreading and designing new TB control interventions.

NewsImplantable living materials autonomously deliver therapeutics using contained engineered bacteria
Researchers have introduced an implantable “living material” that contains bacteria that sense infections. It can release these therapeutic molecules on demand, while keeping them physically separated from the surrounding tissue.

NewsBacteria may hold a cancer treatment clue
A review argues that tumors with reproducibly poor prognosis outcomes may share an overlooked feature: bacterial infection within the tumor microenvironment. These bacteria may weaken treatment by altering local immunity, damaging tissue structure, and even inactivating chemotherapeutic drugs.

NewsProbiotic Lactobacillus rhamnosus CMU-pb-7 shows promise in alleviating diabetic nephropathy via antioxidative pathway
Rats with diabetic nephropathy treated with the probiotic strain Lactobacillus rhamnosus CMU-pb-7 showed marked improvements in general condition and serum biochemical profiles, including significant reductions in cholesterol, triglycerides, blood urea nitrogen, and serum creatinine.

NewsStudy quantifies the staggering economic toll of TB
Researchers have found that TB wipes out an estimated 0.8 per cent of the world’s total economic potential every year. Losses are concentrated overwhelmingly in low- and middle-income countries, especially in South Asia and sub-Saharan Africa.

NewsResearchers find increased bacteria infection in patients with chronic lung disease
A new study has found that people with bronchiectasis and chronic sinus disease were more likely to have mucus samples that tested positive for Pseudomonas aeruginosa. It suggests that doctors caring for patients with bronchiectasis may need to pay closer attention to sinus disease and bacterial testing.

NewsFriendly skin bacteria offer hope to beat eczema
Friendly skin bacteria could hold the key to stopping eczema in its tracks, according to researchers. A new study reveals harmless microbes living on our skin release powerful molecules that can shut down the inflammatory chaos triggered by Staphylococcus aureus, the bug long known to wreak havoc in eczema.

NewsMarine-inspired sunscreen ingredient made by E. coli
Researchers have engineered microbial “cell factories” to sustainably produce the UV-protective compound gadusol, which could eventually serve as a sunscreen ingredient and an antioxidant additive. Gadusol, found in the eggs of various fish and other marine organisms, helps protect against ultraviolet damage.

NewsFlawed but correctable research hindered progress in infection-triggered chronic conditions
Researchers contend that studies of infection-associated chronic illnesses such as Lyme disease and COVID-19 suffer recurring problems such as the failure to prove participants have the relevant pathogen.

NewsEurope advances genomic surveillance of CCRE with landmark multi-country study
New survey results provide the most comprehensive genomic picture to date of carbapenem- and/or colistin-resistant Enterobacterales (CCRE) across hospitals in Europe.

NewsBronchiectasis and NTM Care Center Network expands to 62 centers
The Bronchiectasis and NTM Association has accepted one new Care Center and three new Clinical Associate Center sites into the Bronchiectasis and NTM Care Center Network (CCN). The CCN includes 62 centers across the United States.

NewsThe hunt for red: Chromatin-mediated upregulation of Monascus pigments in Talaromyces purpurogenus OUCMDZ-019 via disruption of Ash2
The industrial application of Monascus pigments has been hindered by three key bottlenecks: unstable yield, poor environmental stability, and the risk of contamination by citrinin. Researchers adopted an epigenetic derepression strategy to unlock the hidden biosynthetic potential of MPs in Talaromyces purpurogenus OUCMDZ-019.

NewsPenn researchers create AI tool to speed antibiotic discovery
Researchers have developed a novel, AI-powered method for turning promising but imperfect antibiotic candidates into more potent ones. ApexGO starts with a small number of imperfect candidates and improves them step by step, using a predictive algorithm to evaluate each modification and guide the next.

NewsThe fog is alive - with tiny helpers
What if fog isn’t just misty air, but a living ecosystem? This question hung over cloud researcher Thi Thuong Thuong Cao. As a PhD student at Arizona State University, her curiosity led her from knocking on the doors of microbiologists and chemists, to sampling fog before sunrise in Pennsylvania, to ...

NewsBody weight affects your gut microbiota
A new study demonstrates that there is a correlation between gut microbiota and body weight. Researchers also observed that having a high BMI is detrimental to gut microbiota.
