NewsViruses that kill toxic algae may increase risks for people and ecosystems
New laboratory research shows that when viruses attack a species that forms toxic algal blooms, those thick, blue-green slicks that choke waterways and that threaten ecosystems, drinking water, and public health, what results might be even worse than before the infection.

NewsStudy uncovers why so many microbes fail to grow in the lab
Many microorganisms die when attempts are made to cultivate them. A new study suggests that that their survival does not depend solely on the needs of individual microbes but on a hidden web of relationships that can be caused to collapse by even small structural changes.

NewsNew vaccine protects against swine, human and bird flu
Annual flu shots could become a thing of the past under a new vaccine strategy. A new study describes a vaccine that protects against H1N1 swine flu and can also protect against influenza in humans and birds.

NewsScientists ID previously unknown enzymes that can produce potentially antimicrobial agents
Micro-organisms generate potential agents for combating bacteria and fungi. Researchers have identified and optimized enzymes that can specifically generate a certain functional group of these natural substances, expanding the toolkit of potential agents.

NewsTargeted nanoparticles show promise for more effective antifungal treatments
Researchers have developed a new nanotechnology-based approach that could improve treatment of fungal infections, particularly those caused by the increasingly drug-resistant Candida species.

NewsActivating ‘jumping genes’ speeds up bacterial evolution from decades to weeks
Scientists have developed a system to control and accelerate the evolution of changes in the bacterial genome structure, targeting small ‘jumping genes’, or DNA sequences known as insertion sequences.

NewsCOVID-19 caused by the Omicron variant in lung transplant recipients: a single center case series
A new study investigates the risk factors for developing severe disease in lung transplant patients as a result of the Omicron variant of Covid-19.

NewsHeart rhythm disorder traced to bacterium lurking in our gums
A new study finds that a gum disease bacterium can slip into the bloodstream and infiltrate the heart. There, it drives scar tissue buildup—known as fibrosis—distorting the heart’s architecture, interfering with electrical signals, and raising the risk of atrial fibrillation (AFib).

NewsBacterium yields secrets of how it produces ‘organic dishwashing liquid’ to degrade oil
The marine bacterium Alcanivorax borkumensis feeds on oil by producing an ’organic dishwashing liquid’ which it uses to attach itself to oil droplets. Researchers have now discovered the mechanism by which this “organic dishwashing liquid” is synthesized.

NewsMicrobial ‘phosphorus gatekeeping’ found at center of study exploring 700,000 years of iconic coastline
A new study has dug deep into the past of the coastal dunes of an iconic Queensland location in a bid to better understand how microscopic processes in the soil support some of the most biodiverse landscapes on Earth.

NewsAntibiotics taken during infancy linked to early puberty in girls
Girls given antibiotics during their first year of life, especially in the first three months, are more likely to enter puberty at an earlier age, according to new research.

NewsProbiotic supplementation may help reduce chemotherapy side effects in breast cancer
A new study shows that probiotics with seven strains have a potential effect in patients with breast cancer, especially in the improvement of common chemotherapy-related side effects such as fatigue and nausea.

NewsNew film series ‘The Deadly Five’ highlights global animal infectious diseases
The EU-funded WiLiMan-ID project is excited to announce the launch of a brand-new short film series, The Deadly Five. This series is aimed at raising awareness of five critical animal infectious diseases, classified as high priority.

NewsTissue geometry drives bacterial infection: new mechanism uncovered
Researrchers have uncovered a novel mechanism by which tissue geometry regulates bacterial infection dynamics. The study employs a multidisciplinary approach to reveal how host tissue structure, mechanical forces, and cellular signaling shape infection patterns.

NewsResearchers reveal how fungi ‘manipulate’ the course of tumors
In pancreatic ductal adenocarcinoma (PDA), the abnormal colonization of fungal communities has become a research hotspot. New research indicates that Malassezia is not only a ’marker’ in the tumor microenvironment but also a potential driver of cancer development.

NewsResearchers pioneer novel, needle-free, live-attenuated influenza vaccines with broad protection
Researchers have achieved a significant breakthrough in developing broadly protective, live-attenuated influenza vaccines (LAIV).
