NewsNew research offers avenue to explore relationship between Alzheimer’s and HIV
Researchers have created an animal model that helps resolve questions about the relationship between HIV and Alzheimer’s disease (AD). The virus that drives the root cause of AD initiates a complex chain that, with other disease partners, drives nerve cell injury and cognitive impairments for AD pathology.

NewsSymposium commemorating the 50th anniversary of the discovery of the Hantaan virus successfully held
A symposium commemorating the 50th anniversary of the discovery of the Hantaan virus celebrated the historical achievement of the late Dr. Lee Ho-wang and reviewed the historical significance of Hantaan virus research, its results, and future infectious disease response strategies.

NewsPlant health: New joint factsheet outlines synergy between Horizon Europe projects FORSAID, CERBERUS and STELLA
One of the biggest threats to Europe’s forests and farms is the spread of biotic stressors, capable of reversing decades of cultivation and conservation. As part of its efforts to address this challenge, the EU has mobilised three sister projects - FORSAID, CERBERUS and STELLA.

NewsAMI calls for marine microbes to be at the heart of Europe’s future ocean policy
Applied Microbiology International (AMI) has responded to the European Commission’s consultation on the proposed EU Ocean Act, highlighting the essential contribution of marine microorganisms to ocean health, climate regulation, biodiversity and the blue bioeconomy.

NewsHeatwaves inhibit antibiotic resistance in soils - but at a price
Heatwaves temporarily reduce the amount of resistance genes in the soil, but heat and droughts are also causing significant damage to soils and ecosystems. The temporary dip in resistance therefore does not mean that the health risks from antibiotic resistance disappear.

NewsProbiotic use surges - but microbiome-supportive food consumption stagnates
New research finds that probiotic supplement use has surged in the United States, while the consumption of microbiome-supportive foods has remained virtually unchanged. According to a study published in Clinical Gastroenterology and Hepatology, the consumption of probiotic supplements increased 287% among adults from 2009-2023 and 786% among ...

NewsToxic tail: Biologists find a hidden weak spot in how bacteria build the tails they use to move
New research has uncovered a previously unknown vulnerability in how bacteria build the whip-like tails they use to move. Building these tails can put stress on the protective wall surrounding a bacterial cell, and uncovered systems bacteria use to keep that stress from becoming destructive.

NewsHelicobacter pylori exposure may be linked to more than 1 in 5 bowel cancer cases worldwide
Exposure to the stomach microbe Helicobacter pylori may be associated with more than 1 in 5 cases of bowel cancer worldwide, suggests an exploratory risk attribution study - and those born in more recent decades may be more at risk of the disease after exposure.

NewsBacterial trial fails to demonstrate early asthma prevention - prompting rethink of 'hygiene hypothesis'
A national clinical trial has found that treating young children with an oral bacterial extract did not reduce the risk of severe wheezing and respiratory illnesses that can precede asthma, potentially prompting researchers to rethink aspects of the hygiene hypothesis.

NewsVaccine protects against multiple fungal infections without hurting the gut
A vaccine created to battle multiple life-threatening fungal infections is successful in achieving protective immunity in pre-clinical animal models while also maintaining the biodiversity of the gut microbiome, according to a new study.

NewsFaster diagnostics, deeper insights: Researchers strengthen response to Ebola outbreaks
Two studies provide important insights into the challenges of responding to outbreaks - one demonstrates how diagnostic tests can be evaluated rapidly during an outbreak; the other investigates the biological properties of the 2026 BDBV strain and whether an existing Ebola vaccine could offer cross-protection.

NewsCommonly used cancer drugs boost MRSA antibiotics – new research
Scientists tested five anti-cancer drugs and revealed that four of them helped penicillin-type antibiotics to kill MRSA. These drugs interfere with the bacteria’s ability to make DNA, making the bacteria more vulnerable to the antibiotics.

NewsResearch explores why strep throat can linger, even after treatment with antibiotics
Streptococcal sore throat can linger even after treatment, turning otherwise healthy children into carriers. Using whole genome sequencing, researchers hope to discover why.

NewsMpox outbreak in 2022 caused by less severe form of the virus
The strain of Mpox behind the 2022 outbreak was a weakened form of the virus, which may have helped to spread it faster, a new study reports. The findings show that the virus acquired mutations before it spread globally.

NewsShould adults with autoimmune rheumatic conditions receive updated COVID-19 vaccines?
Adults with autoimmune rheumatic conditions who developed COVID-19 and received booster or updated (2023-2024) COVID-19 vaccines were less likely to be hospitalized for COVID-19 compared to those who received only the initial series vaccines or who were unvaccinated.

NewsRiver drinking water sources may face greater antibiotic resistance risks than reservoirs, study finds
A basin-wide study of 13 drinking water sources in China’s Poyang Lake region shows that water source type can strongly shape the occurrence and spread of antibiotics, antibiotic resistance genes, and resistant bacteria.

NewsBiochar can act as an ‘interface engineer’ to reshape the hidden world around plant roots
A new review shows how biochar simultaneously modifies soil structure, chemistry and microbial communities in the rhizosphere, offering a framework for more precise and sustainable agricultural use.

NewsSuper-resolution imaging reveals details inside living cells
A new fluorescence microscopy technique that generates super-resolution images from a single camera exposure could help researchers study rapid movements within cells that are difficult to capture with existing methods.

NewsHigh-dose flu vaccine beneficial for older people with lung disease
The risk of being hospitalised for flu or pneumonia can be reduced with a high-dose flu vaccine for older people with chronic lung disease, according to the combined results of two large clinical trials.
