NewsA closer look at immune ‘memory’ - and how long it lasts
A new review shares recent advances from the field of immune memory and highlights key steps we might take to develop even more effective, longer-lasting immunity against deadly diseases.

NewsA built-in ‘hairpin’ prevents rogue CRISPR RNAs
A new study reveals that many CRISPR-Cas13 systems utilize an RNA to prevent the formation of extraneous CRISPR RNA. With the first repeat, this protective RNA forms a stable structure resembling a hairpin. It points to a remarkable case of convergent evolution.

NewsFunctional traits, not phylogeny, drive gut microbial assembly in estuarine fish
By examining the gut microbiota of 61 sympatric fish species within the ecologically diverse Pearl River Estuary, researchers utilized this “natural laboratory” to disentangle complex biological drivers without the interference of geographical variation.

NewsGlobal strategy to combat drug‑resistant fungi is about to change
An increasing number of fungi are becoming resistant to medication, posing serious risks for patients with weakened immune systems. That is why fifty researchers from around the world are calling for action against drug‑resistant fungi.
-
NewsAI spots hidden behavior patterns in self-organizing bacteria
A custom-built artificial intelligence system has helped to uncover how bacterial communities organize themselves, showing that the earliest moments of a biological transition carry far more information than previously considered.
-
NewsCat viruses offer window into human oncogenesis
Cats are not just beloved companions; they are emerging as key “research partners” in unravelling viral cancer mechanisms. A new review explores how feline tumour viruses offer vital insights into human oncology and viral carcinogenesis from a comparative oncology perspective.

NewsIntegration of two genes: A valuable strategy for developing virus-resistant tomatoes
Researchers have demonstrated that integration of Ty-1/Ty-3 and Ty-6 resistance genes in tomato plants can confer highly robust resistance to begomoviruses.
-
NewsUltrasensitive test reveals evidence of previously undetected tuberculosis in Boston Hospital patients
Researchers have discovered an unexpectedly high prevalence of Mycobacterium tuberculosis DNA (TB DNA) in patients hospitalized in Boston, suggesting that tuberculosis disease may be significantly underdiagnosed in the United States.
-
NewsLonger-term plankton species diversity is independent of ocean mixing
A new study identifies correlations between turbulence, plankton diversity and aggregate abundance in marine coastal regions over longer time periods, providing new insights into marine ecosystems.

NewsUnraveling the complexities of the Borna disease virus 1
Researchers have published the first detailed structural description of the nucleoprotein-RNA complex in the family Bornaviridae. Their observations revealed the three-dimensional structure of this nucleoprotein-RNA complex, showing ring-like assemblies and viral RNA binds in the inner groove.
-
NewsNew bite-sized CRISPR molecule may open doors for therapeutic genome editing
The safest, most accurate gene-editing tools don’t fit inside viral delivery mechanisms that could target them to specific cell types or tissues inside the human body. Researchers have developed a smaller pair of “molecular scissors” for gene editing that could make site-specific delivery within the body possible.

NewsResearchers uncover how obesity impairs vaccine response
New findings reveal that obesity significantly impaired the quality and longevity of antibody responses to a Pseudomonas aeruginosa vaccine in a mouse model. The impaired antibody production was due to defects in germinal centers.
-
NewsShorter antibiotic courses show similar outcomes to longer use for some pneumonia patients
A multicenter target trial emulation found that for eligible patients hospitalized with community-acquired pneumonia (CAP), health outcomes were similar whether they received a three- to four-day course of antibiotics or a course lasting five days or more.
-
NewsExtracellular vesicle RNAs offer new hope for diagnosing and treating chronic inflammatory bowel disease
Extracellular vesicle-associated RNAs can serve as non-invasive biomarkers for early inflammatory bowel disease detection and disease monitoring, and also hold great potential as targets for next-generation targeted therapies, according to a new review.
-
NewsAutism and ADHD: Epigenetic changes at birth associated with an infant’s microbiome and neurodevelopment
Epigenetic changes present at birth can impact how an infant’s gut microbiome develops during their first year. Researchers also identified specific epigenetic changes and gut microbes that were associated with signs of autism spectrum disorder (ASD) and ADHD when the children were three years old.

NewsNew biodegradable wash removes pesticides and extends produce shelf life
Researchers have developed a natural, biodegradable wash that removed up to 96 per cent of pesticide residue from fruit and slowed browning and moisture loss.
-
NewsBetween 2.4 and 4.1 million people estimated to be living with chronic hepatitis B infection in Europe
Chronic hepatitis B is substantially prevalent across the European Union and European Economic Area (EU/EEA), affecting an estimated 0.7% of the population in the region in 2022, according to a new study.

NewsScientists discover the antibacterial potential of ‘hero’ Korean skincare ingredient
Fans of Korean skincare may be familiar with ‘hero ingredient’ Madecassic acid for its skin-soothing properties, but researchers have revealed its greater potential for use in the battle against antibiotic resistance.
-
NewsWildlife trade increases pathogen transmission
A study combining forty years of legal and illegal wildlife import-export data with compilations of host–pathogen relationships found that wild mammals that are traded are 1.5 times more likely to share infectious agents with humans than those that are not involved in trade.

NewsResearchers explore potential link between COVID-19 and lung cancer risk
New findings have identified a potential association between COVID-19 and increased lung cancer risk, driven by underlying biological mechanisms in the lung. The study integrates human clinical data with mechanistic research in animal and cellular models.
