NewsDo stranded dolphins have Alzheimer’s disease - and how are cyanobacteria involved?
Scientists have come up with an unusual hypothesis: perhaps dolphins become disoriented by suffering from a form of Alzheimer’s disease. It appears that Alzheimer’s-type neuropathology and disorientation may result from chronic exposure to toxic molecules produced by cyanobacteria.

NewsNew herpes virus–based vaccine could cure cancer in the future without side effects
The Herpes simplex virus is a widespread virus that often causes cold sores, and most people carry it. By removing a virulence gene, i.e. a gene that makes the virus harmful to humans, the herpes virus can be repurposed as a cancer vaccine.

NewsQdenga vaccine shows effectiveness against dengue under real-world conditions during Brazil’s 2024 outbreak
An international team of researchers has demonstrated that the tetravalent dengue vaccine Qdenga provides significant protection against the disease under real-world conditions, during the large 2024 epidemic in São Paulo, Brazil.

NewsHigh-latitude phytoplankton particularly sensitive to climate change
A team of researchers have investigated how high-latitude phytoplankton communities responded to ancient climate warming. High-latitude communities are historically understudied and likely to be particularly sensitive to human-driven climate change.

NewsNew insights into how pathogens build protein machinery for survival in the gut
New research reveals how pathogenic bacteria construct tiny protein-based compartments, known as Eut microcompartments, which enable them to digest ethanolamine - a nutrient commonly found in the gut.

NewsIndia could bear biggest impact from chikungunya, new maps suggest
Based on existing evidence of chikungunya transmission, an infectious disease model predicts 14.4 million people could be at risk of infections globally each year, with 5.1 million people at risk in India.

NewsCorals might be adapting to climate change, study shows
Researchers showed that despite a gradual increase in ocean acidity levels over the past 200 years, some corals seem to be able to adjust and continue to generate their hard, stony skeleton structures.

NewsScientists uncover molecular mechanisms for bacterial lipid transport
Researchers have successfully applied cryo-electron microscopy (cryo-EM) to unveil the molecular structures of critical protein machines that transport lipids and maintain the outer membrane (OM) barrier of Gram-negative bacteria.

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.
