NewsPersistent herpes zoster-associated pain: New review uncovers mechanisms and supports earlier intervention
For millions, herpes zoster pain does not end when the rash fades. Postherpetic neuralgia can last for years, devastating quality of life. A comprehensive review has mapped the full cascade of mechanisms driving this persistent pain, providing support for earlier, more aggressive treatment.

NewsEnvironmental fungi found to alter vaginal mycobiome and cervical disease progression during dysbiosis
Scientists have demonstrated for the first time that environmental fungi actively interact with the vaginal bacteriome and mycobiome with likely implications for cervical disease progression.

NewsNatural compound may help boost vaccine responses
A team of researchers has found that the naturally occurring compound spermidine can help boost vaccine response in older adults by reducing molecular markers of immune system ageing.

NewsLong-term hepatitis control efforts dramatically reduce HBV and HCV burden in Japan
Researchers have estimated that the number of HBV infections in Japan could decline gradually down to around 200,000 cases by 2050, down from an estimate of 923,000 to 940,000 cases in 2020. HCV is estimated to decline to less than 20,000 cases.

NewsLandmark study reveals ‘megacluster’ of bacterial genes behind arsenal of potent antibiotics
A newly discovered “megacluster” of genes in Streptomyces bacteria produces four new natural product antibiotics that work together to stop rival bacteria.

NewsBiofilm “scaffolds” protect bacterium responsible for food poisoning from antibiotics
Bacillus cereus, which is responsible for human infections and food poisoning, builds organized communities that act as a ‘shield’ against antibiotics, a new study reveals.

NewsHealthy infant microbiomes appear to protect against malaria
A small preliminary study shows that 6-week-old infants with healthy gut microbiomes are less likely to contract malaria in their first year of life, suggesting the intriguing possibility that treatments such as probiotics could be protective against malaria.

NewsSoil pH regulates the symbiosis between stink bugs and gut bacteria
A new study shows soil pH regulates the symbiosis between stink bugs and gut bacteria, revealing alternative strategies to pesticides in agricultural pest control.
-
NewsThe miracle microbes that could save crops from impact of rising sea levels
A new study reveals a previously unknown mechanism by which microbes help plants – including maize, tomato and rapeseed - survive in harsh environments, with major implications for agriculture worldwide.
-
NewsMicrobes rewrite the rules of cancer immunotherapy by triggering immunogenic cell death
A new study reveals that microbiota and their metabolites can effectively reprogram immunogenic cell death (ICD), a unique form of cell death that activates the body‘s immune system against tumors, transforming immunologically “cold” therapy-resistant tumors into “hot” responsive ones.
-
NewsRight versus left: Colorectal cancer’s two microbial worlds
New research reveals that the mucosal microbiome varies dramatically depending on whether a tumor arises on the right or left side of the colorectum, suggesting that the microbial environment surrounding tumors may be as geographically distinct as the tumors themselves.
-
NewsRed meat may worsen IBD — here’s what could help
New research sheds light on why red meat may worsen inflammatory bowel disease (IBD). Researchers found that mice fed a beef-based diet developed the most severe intestinal inflammation, but those consuming pea protein showed only mild symptoms.
-
NewsLarge-scale microbiome study identifies robust colorectal cancer signature
Researchers have identified a robust microbial signature associated with colorectal cancer. The study also analysed 906 intestinal tissue samples to compare stool-based microbiome signals with microbes found directly in tumour tissue.
-
NewsScientists unlock gut-healing power of fruits and nuts paired with the right gut microbes
Scientists discovered how a naturally occurring microbial metabolite called urolithin A, which is generated by gut bacteria after digestion of foods such as pomegranates, walnuts and berries, activates a protective pathway in the intestine that may help preserve gut health.

NewsThe climate crisis threatens river microbial biodiversity
A study warns that the biodiversity and biological functions of aquatic fungi in rivers are at risk due to rising temperatures, prolonged dry periods and the loss of riparian vegetation caused by climate change.
-
NewsA soil bacterium turns electricity and carbon dioxide into acetate
A new study shows that a soil bacterium can directly reduce Fe(III) minerals, exchange electrons with electrodes, and use electrode-derived electrons to convert carbon dioxide into acetate under autotrophic conditions.

NewsDiscovery of severe pneumonia subtypes could lead to tailored treatments for life-threating disease
New research shows that severe pneumonia has three different subtypes, helping explain why some patients in intensive care units (ICUs) recover quickly, while for other patients the disease can be life-threatening.
-
NewsHidden protein linked to severe COVID-19 and lung disease risk
A genetic difference carried by nearly one in three people may increase the risk of severe COVID-19 and lung fibrosis by disrupting the function of a previously unknown protein, according to a new study.

NewsThe early immune clues that determine who develops TB
An early view of the immune response to bacteria in the lungs provides clues as to why some people keep TB in check, while others develop disease, suggesting new ways to intervene earlier and stop TB.

NewsNative litter jump-starts microbial recovery in mine soils
By applying litter collected from nearby native woodland to rehabilitated mine land, a study has shown increases in microbial diversity, enrichment of carbon- and nitrogen-cycling microorganisms, and stronger biochemical potential for soil organic matter decomposition and nitrogen mobilization.
