NewsEmerging serum biomarkers for chronic hepatitis B: Focus on serum HBV RNA and HBcrAg
There is a pressing need for non-invasive biomarkers that can accurately reflect the activity of the hepatitis B viral reservoir and predict clinical outcomes. This review synthesizes the evidence for two such promising biomarkers: serum HBV RNA and hepatitis B core-related antigen (HBcrAg).

NewsUnder half in US would recommend some routine vaccinations during pregnancy
Data from a new APPC health survey finds a reluctance among the public to recommend that someone who is pregnant get a Covid-19 vaccine, with just 38% saying they would do so. Less than half of the survey respondents (42%) say it is safe to take an mRNA Covid-19 vaccine during pregnancy.

NewsFungi set the stage for life on land hundreds of millions of years earlier than thought
New research indicates the diversification of fungi hundreds of millions of years before the emergence of land plants. It suggests a common ancestor of living fungi dating to roughly 1.4–0.9 billion years ago.

NewsRisk of long COVID in kids doubles after second infection
Children and adolescents were twice as likely to experience long COVID after catching COVID for the second time, compared to their peers with a single previous infection, results running counter to the popular perceptions that COVID in children is ‘mild’.

News‘Alarming’ rise in newborn babies with antibiotic-resistant infections, researchers find
Researchers are calling for an urgent overhaul of diagnostic and treatment guidelines for infections in newborn babies, after a study revealed frontline treatments for sepsis are no longer effective to treat the majority of bacterial infections.

NewsFriendly soil fungus could replace chemical sprays in battle against crop diseases
A common soil fungus could help farmers reduce their reliance on synthetic fungicides by producing natural airborne chemicals that suppress plant diseases. Trichoderma hamatum releases volatile organic compounds (VOCs) that inhibit the growth of crop pathogens.

NewsResearchers uncover HIV mystery that could unlock the path to a cure
Researchers have identified for the first time how HIV enters a dormant state in infected cells that allows the virus to “hide” from the immune system and current treatments. HIV orchestrates its own survival by reprogramming host cells to create the perfect hiding place.

NewsBiogas slurry boosts biochar’s climate benefits by reshaping soil microbes
A new study finds that pairing biochar with biogas slurry, a nutrient-rich liquid fertilizer from biogas production, can reshape soil microbial communities and significantly alter emissions of carbon dioxide (CO₂), nitrous oxide (N₂O), and methane (CH₄).

NewsCell death in microalgae resembles that in humans
For the first time, researchers have observed the same type of programmed cell death in microalgae as in humans. The discovery shows that this central biological process is older than previously thought.

NewsNew clues in how plant microbiomes protect against bacterial speck disease
A new study gives new clues on how a tomato plant’s microbiome can be used to combat the bacterial speck pathogen. Researchers found populations of Xanthomonas and Pseudomonas bacteria on the plants that had developed a resistance against bacterial speck.

NewsNatural antimicrobial drugs found in pollen could help us protect bee colonies from infection
Pollen gathered by honeybees contains antimicrobial-producing bacteria that protect the hive against disease, a new study reveals. The same beneficial bacteria occur in pollen stores of honeybee colonies and on pollen of nearby plants.

NewsStudy shows HPV vaccine protects vaccinated — and unvaccinated — women
A study has found that the introduction of the human papillomavirus (HPV) vaccine in community settings is highly effective in protecting young women from infections caused by the cervical-cancer-causing virus—including women who didn’t even receive the vaccine.

NewsScientists reveal functional RNA splitting mechanism behind origin of Type V CRISPR systems
Researchers have uncovered the molecular innovation that led to the origin of Type V CRISPR-Cas immune systems. Their findings show that the functional splitting of transposon-derived RNAs was the critical innovation driving the emergence of Type V CRISPR-Cas immunity.

NewsDeadly pathogens found in commercial raw cat foods
An analysis of commercial raw cat foods detected disease-causing microbes, including some that are resistant to antibiotics, creating risks for both pets and their owners, according to a new study.

NewsStudy shows mucus contains molecules that block Salmonella infection
Researchers have identified mucins that defend against Salmonella and other bacteria that cause diarrhea. They now hope to mimic this defense system to create synthetic mucins that could help prevent or treat illness in soldiers or other people at risk of exposure to Salmonella.

NewsFungal toxin offers colonization support - in small doses
The yeast fungus Candida albicans not only uses the toxin candidalysin to cause infections, but also to colonize the oral mucosa inconspicuously – but only in finely balanced amounts. Too little toxin prevents oral colonization, too much triggers the immune system.

NewsSuper-resistant bacteria found in wild birds at a rehabilitation center in Brazil
Researchers have found antibiotic-resistant bacterial clones in wild birds at a rehabilitation center. The identified Escherichia coli clones have been found in community- and hospital-acquired human infections worldwide, and were present in the intestinal tracts of a vulture and an owl.

NewsTwo-drug combination shows promise in helping heal chronic wounds
By adding small doses of a simple molecule called chlorate to standard antibiotics, researchers foundthe combination proved 10,000 times more effective at killing bacterial cells in the lab than single-drug antibiotics.

NewsHow the gut microbiome helps Japanese macaques eat with the seasons
A study shows that both the composition and fermentative ability of the Japanese macaque gut microbiome shift flexibly across seasons, while the latter in particular increased during the harsh winter when macaques relied on leaves.

NewsGenetic culprits IDed in capture of 100 years of antibiotic resistance evolution
The genetic culprits responsible for the spread of multidrug resistance (MDR) in bacteria have been identified by new research mapping 100 years of bacterial evolution.
