NewsPotential biomarker for the development of long COVID identified
A research team has demonstrated that a specific component of the immune system (PTX-3) remains at significantly higher levels in the blood of patients who have suffered from severe COVID-19, even months after the acute infection has subsided.

NewsPeptide study paves path toward new weapon against antibiotic-resistant bacteria
New research into antimicrobial peptides, small chains of amino acids able to damage bacterial cells, shows why some peptides are more effective at doing that and also why some cells are more vulnerable.

NewsNew biochar technology promises breakthrough in soil clean-up and crop safety
Scientists have unveiled a pioneering method that could help farmers reclaim lands blighted by toxic metals and boost the safety of crops grown in contaminated soils. Phosphorus-modified biochar can reduce the threat posed by heavy metals in agricultural soils near mining areas.

NewsInvasive mosquito vector species detected in surveillance traps in UK
A study describes the detection of invasive mosquito eggs in the United Kingdom in 2023 and 2024, suggesting an increasing incidence of importation of these species, potentially putting new populations at risk of disease transmission.

NewsCould bacteria help fix the smoky taste of wildfire-tainted wine?
New laboratory experiments show that a bacterium that lives on grape plants can break down guaiacol—an unpleasant-tasting substance which ruins wines made from grapes exposed to wildfire smoke.
-
NewsPathogenic yeast strains found in urban air but not along the coast
A pilot study has found that urban air contained pathogenic strains of Candida yeast that were absent in coastal air samples, revealing a potential transmission method.

NewsMicrobial DNA sequencing reveals nutrient pollution and climate change reinforce lake eutrophication
A new study using DNA sequencing of lakebed microbes reveals that nutrient pollution from agricultural runoff and climate change amplify each other in ways that profoundly affect the health of lake ecosystems.

NewsSome plants can make their own fertilizer - scientists say they learned it more than once
In a new study, scientists show that chemical receptors that plants use to recognize nitrogen-fixing bacteria have developed the same function independently on at least three separate occasions through a process called convergent evolution.

NewsBrain imaging technique helps uncover the molecular basis of long COVID brain fog
A research team has made a significant breakthrough in understanding the cause of Long COVID brain fog. They hypothesized that patients with brain fog might exhibit disrupted expression of AMPA receptors (AMPARs)based on prior research into psychiatric and neurological disorders.

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.
