NewsHow reactive oxygen species target viruses differently: new clues for safer water disinfection
A new study systematically explored how reactive oxygen species (ROS) inactivate viruses with distinct structures. The results revealed clear heterogeneity: enveloped RNA viruses were most susceptible to oxidation, while double-stranded DNA viruses showed strong resistance.

NewsMucosal virome and host transcriptome interactions reveal viral influence in colorectal polyp development
A new study has provided the first integrated mucosal virome-transcriptome landscape of colorectal polyps, the precursors of colorectal cancer, offering new insights into viral-host interactions at this early disease stage.

NewsPlant extracts show promise in reducing human pathogen risks in agricultural soils
A new study has revealed that natural plant extracts can significantly lower the risks posed by human bacterial pathogens in manure amended agricultural soils. The eco friendly strategy disrupts the communication systems that bacteria use to coordinate harmful activities.

NewsA viral fitness-constraint strategy exploits the structural and functional limitations of viral evolution
Researchers have revealed two innovative strategies for the development of durable and broadly neutralizing antibodies against SARS-CoV-2. Their study proposes the immune trajectory strategy and the viral fitness-constraint strategy.

NewsDynamic duo of bacteria could change Mars dust into versatile building material for first human colonists
Scientists are investigating a bacterial co-culture mixed with Martian regolith as a potential feedstock for 3D printing on Mars. At the intersection of astrobiology, geochemistry, material science, construction engineering, and robotics, this synergistic system could revolutionize the potential for construction on the Red Planet.

NewsCorticosteroid use does not appear to increase infectious complications in non-COVID-19 pneumonia
A systematic review and meta-analysis found that adjunct corticosteroids probably reduce short-term mortality in cases of severe pneumonia and acute respiratory distress syndrome and may reduce secondary shock in severe pneumonia.

NewsLong-term HIV control: Could this combination therapy be the key?
A new study shows it may be possible to control HIV without long-term antiviral treatment — an advance that points the way toward a possible cure for a disease that affects 40 million people around the world.
-
NewsCan a synthetic compound help plants recruit beneficial bacteria?
Researchers examining how a DMA analog called proline-2’-deoxymugineic acid (PDMA) influences the rhizosphere microbiome of peanut plants found that PDMA increased the abundance of beneficial microbes, particularly those within the phylum Actinobacteria.

News Lack of dietary iron may impair immune cells’ ability to fight influenza
New research suggests that a lack of dietary iron can negatively affect the ability of immune cells to respond to viral infection in the lungs. In mice with dietary iron deficiency and influenza, immune cells struggled to produce a key signal needed to fight viruses and did not regain this ability.

NewsNobel Prize-awarded material that punctures and kills bacteria
Bacteria that multiply on surfaces are a major headache in healthcare. Researchers have found a new weapon to fight these hotbeds of bacterial growth – metal-organic frameworks. These materials can physically impale, puncture and kill bacteria before they have time to attach to the surface.

NewsHalf of all people living with HIV in Europe are diagnosed late
Europe is failing to test and treat HIV early, with over half of all diagnoses in 2024 being made too late for optimal treatment, according to new data from ECDC and WHO/Europe.

NewsNew guideline on pre-exposure and postexposure HIV prevention
Multiple pre-exposure (PrEP) and postexposure (PEP) treatments are now available to prevent HIV infection. An updated Canadian guideline contains 31 recommendations and 10 good practice statements to help clinicians and other health care professionals offer these options to patients.

NewsBird flu viruses are resistant to fever, making them a major threat to humans
Bird flu viruses are a particular threat to humans because they can replicate at temperatures higher than a typical fever, one of the body’s ways of stopping viruses in their tracks, according to new research.

NewsMicroplastics disrupt gut microbiome and fermentation in farm animals
Microplastics, tiny plastic particles pervasive in agricultural environments, interact with and disrupt the microbial ecosystem in the rumen – the first stomach chamber of cattle, reveals an international study.

NewsMetabolites produced in the intestine play a central role in controlling obesity and diabetes
A study has identified a group of metabolites that travel from the intestine to the liver and then to the heart, where they are pumped throughout the body. These metabolites play an important role in controlling metabolic pathways in the liver and insulin sensitivity.

NewsAcid rain may be training soil bacteria to become more deadly
Acid rain from fossil fuel pollution may be quietly training soil bacteria to become longer-lived, more transmissible, and more deadly, according to a new study that tracks how a notorious foodborne pathogen rapidly evolved under simulated acid deposition.

NewsCuring hepatitis C can rebalance immunity in Indonesians living with HIV
A new study provides the first longitudinal immunological data on HIV/HCV-coinfected individuals in Southeast Asia, underscoring the importance of early hepatitis C treatment to prevent long-term immune and liver complications.

NewsParkinson’s drug offers basis for new hospital bacterium anti-infectives
Researchers have discovered a promising starting point for the development of new active substances against the hospital germ Pseudomonas aeruginosa.

NewsResearchers warn: Climate change could expand habitats for malaria mosquitoes
A new study shows that future climate change could create more favourable conditions for malaria mosquitoes, exposing millions of people across large parts of Africa to more dangerous mosquito bites.

NewsResearch into zoonotic disease risks requires a One Health approach
A new evidence brief, based on a study by the Juno Evidence Alliance conducted in collaboration with CABI’s One Health Hub, has highlighted that a One Health approach is needed in research into zoonotic disease risks around the world.
