NewsComplexity key to preventing infection after heart surgery
Research indicates that uniform materials could be the culprit behind deadly infections that can occur when using synthetic materials for cardiovascular grafts.

NewsLower tillage boosts the soil’s natural phosphorus cycle - cutting the need for costly fertilizer inputs
Long-term tillage reduction helps to restore the soil’s natural phosphorus cycle, supporting more sustainable nutrient management with less reliance on costly and finite fertilizer inputs, according to a new study published in Sustainable Microbiology.

NewsMacrophage immune cells need constant reminders to retain memories of prior infections
Researchers have discovered that immune cells known as macrophages remain poised to fight repeat infections due to the persistent presence of signaling molecules left behind during previous infections.

NewsPower grids to epidemics: study shows small patterns trigger systemic failures
Why do some systems collapse suddenly after what seems like a minor disturbance? In nature, a local disease outbreak can quickly escalate into an epidemic. New research suggests that in many cases, the key isn’t the entire system – but its smallest building blocks.

NewsBooster jabs reduce the risks of COVID-19 deaths, study finds
Booster vaccines reduced the risk of COVID‑19–related hospitalisation and death, according to a new study of over 3 million adults who had the autumn 2022 vaccine in England.

NewsCOVID-19 vaccination during pregnancy may help prevent preeclampsia
A new multinational study has found that COVID-19 vaccination during pregnancy, particularly when combined with a booster dose, significantly reduces the risk of preeclampsia, a serious and potentially life-threatening pregnancy complication.

NewsDebilitating virus can spread in cool weather, increasing health risk in Europe
Chikungunya virus, a debilitating tropical disease caused by infected mosquito bites, poses a greater health threat in Europe than previously thought because it can be spread when air temperatures are as low as 13 degrees Celsius.

NewsMicrobes harvest metals from meteorites aboard space station
Microorganisms can harvest crucial minerals from rocks and could provide a sustainable alternative to transporting much-needed resources from Earth. Researchers have studied how those microorganisms extract platinum group elements from a meteorite in microgravity, with an experiment conducted aboard the International Space Station.

NewsHow bacteria may promote breast cancer
Researchers have discovered how certain pathogenic bacteria in gut and breast tissue can promote breast cancer development and progression by hijacking a key metabolic enzyme known as spermine oxidase (SMOX).

NewsScientists develop first-of-its-kind antibody to block Epstein Barr virus
Using mice with human antibody genes, scientists have developed new genetically human monoclonal antibodies that prevent two key antigens on the surface of the Epstein Barr virus (EBV) from binding to and entering human immune cells.

NewsStrategic changes in water treatment could prevent disease outbreaks
A breakthrough new study shows how strategic changes in water treatment effectively treated a deadly outbreak of Legionnaires’ Disease. For the first time, the study provides evidence of an outbreak being stopped by introducing disinfection to previously untreated groundwater.

NewsChildren with sleep apnea face higher risk of flu and COVID-19, new study finds
A five-year study has revealed that children with sleep apnea are twice as likely to contract the flu or COVID-19, regardless of their age or weight. Even after undergoing surgery to remove tonsils or adenoids, this increased vulnerability persists due to long-term changes in the immune system.

NewsNew antibody–drug conjugate strategy to block HIV infection
New antibody–drug conjugates (ADCs) combine a CD4 mimic with neutralizing antibodies for enhanced suppression of HIV infection. By targeting the gp120 on the viral envelope via a two-step mechanism, the ADCs effectively block viral entry.

NewsNew clinical guidelines to reduce central line-associated bloodstream infection
Central line-associated bloodstream infections remain a major challenge in ICUs. A team of clinicians has proposed updated guidelines to standardize the clinical practices addressing CLABSI, aiming to reduce infection rates and improve outcomes for critically ill patients.

NewsWebinar: What does it mean when environmental microbiomes are described as resilient?
Environmental microbiomes are often described as ‘resilient’ - but what does that even mean? A free upcoming webinar and coffee hour delivered by Dr Ashley Shade, as part of the Microbes and Social Equity 2026 Speaker Series, aims to find out.

NewsGlobal commitment on display as countries negotiate key annex to the Pandemic Agreement
Member States of the World Health Organization (WHO) concluded a weeklong round of negotiations on draft annex for Pathogen Access and Benefit Sharing (PABS) – a key component of the WHO Pandemic Agreement.

NewsNew biosensor offers early warning system for disease
Researchers have developed a tissue-adhesive sensor for real-time oral health monitoring to combat long-term issues such as gum disease and tooth loss.

NewsBacteria frozen in ancient underground ice cave found to be resistant against 10 modern antibiotics
Researchers tested antibiotic resistance profiles of a bacterial strain that until recently was hidden in a 5,000-year-old layer of ice of an underground ice cave – and found it could be an opportunity for developing new strategies to prevent the rise of antibiotic resistance.

NewsA yeast enzyme helps human cells overcome mitochondrial defects
An international team has experimentally uncoupled nucleotide synthesis from mitochondrial activity using ScURA, a yeast-derived genetic tool now available to the research community that will enable new explorations of cellular metabolism.

NewsRhododendron-derived drugs now made by bacteria
Bioengineered E. coli bacteria can now produce a group of compounds with anticancer, anti-HIV, antidiabetic and anti-inflammatory activities. The compounds, orsellinic acid-derived meroterpenoids, are produced by Rhododendron species.
