NewsEngineered nanobodies improved respiratory defenses in preclinical study
Engineered nanobodies improved protection against multiple viruses by bolstering respiratory mucus. The bispecific design of the nanobodies works against viruses, like influenza, which can normally evade mucosal defenses.

NewsThe brain’s sneakiest houseguest: how a parasite rewrites neuron messages and alters neuroplasticity
A new study describes how Toxoplasma gondii manipulates the behaviour and brain function of its hosts. It explored a new angle by looking at nanoparticles called extracellular vesicles, which cells use to send messages to one another, and carry small regulatory molecules known as microRNAs.

NewsNew study shows how light suppresses virulence in antibiotic-resistant pathogen
Researchers uncover a light-sensitive signaling cascade in Pseudomonas aeruginosa that suppresses biofilm formation and virulence, offering a potential new strategy to combat antibiotic-resistant infections.

NewsSeawater microbes offer new, non-invasive way to detect coral disease, study finds
Researchers have discovered that microorganisms in seawater surrounding corals provide a powerful indicator of coral disease, potentially transforming how reef health is monitored worldwide.

NewsGlobal Virus Network warns of measles resurgence
The Global Virus Network (GVN) has expressed deep concern regarding the ongoing resurgence of measles in the United States and around the globe. Measles is one of the most contagious viral diseases known and can be lethal, particularly in unvaccinated children.

NewsPaper sheds light on human impact of first known ancient pandemic
A new paper examines the Plague of Justinian and its consequences for ancient Jordan. Focusing on the first-known outbreak of bubonic plague in the Mediterranean world, it adds to the historical record on what caused the devastating outbreak that killed millions within the Byzantine Empire.

NewsHidden mpox exposure detected in healthy Nigerian adults, revealing under-recognized transmission
The mpox virus appears to be circulating silently in parts of Nigeria, in many cases without the symptoms typically associated with the disease, according to new research.

NewsHuman nasal passages defend against the common cold and help determine how sick we get
Researchers demonstrate how the cells in our noses work together to defend us from the common cold and suggest that our body’s defense to rhinovirus—not the virus itself—typically predicts whether or not we catch a cold, as well as how bad our symptoms will be.

NewsGolden Gate method enables rapid, fully-synthetic engineering of therapeutically relevant bacteriophages
Researchers have described the first fully synthetic bacteriophage engineering system for Pseudomonas aeruginosa. In this method, researchers engineer bacteriophages synthetically using sequence data rather than bacteriophage isolates.

NewsValneva provides update on Chikungunya vaccine IXCHIQ®
Valneva SE has announced that the company has decided to voluntarily withdraw the biologics license application (BLA) and Investigational New Drug (IND) application for its chikungunya vaccine, IXCHIQ® , in the United States, following suspension of the license by the FDA.

NewsShingles vaccine linked to slower biological aging in older adults
Shingles vaccination not only protects against the disease but may also contribute to slower biological aging in older adults, according to a new study.

News58% of patients affected by 2022 mpox outbreak report lasting physical symptoms
A cohort study found that more than half of those diagnosed with mpox during the 2022 outbreak still had lingering physical effects 11 to 18 months later.

NewsPregnant women hospitalized for COVID-19, and their newborns, have higher complication risk
When hospitalized for COVID-19, pregnant women — and their eventual newborn children — have a higher risk of complications. Research revealed that pregnant women were nearly 3.5 times more likely than non-pregnant women to require respiratory support when hospitalized for COVID-19.

NewsDeadly to amphibians, a fungal strain emerged in Brazil and spread around the world
The fungal infection Batrachochytrium dendrobatidis is responsible for the decline of toad and frog populations across the globe. A new study has pinpointed the origin of the fungal strain.

NewsResearchers discover how a respiratory bacterium obtains essential lipids from the human body and targets fat-rich tissues
A multidisciplinary team has uncovered a key mechanism that allows the human bacterium Mycoplasma pneumoniae—responsible for atypical pneumonia and other respiratory infections—to obtain cholesterol and other essential lipids directly from the human body.

NewsLiquorice root could be effective against upper respiratory tract infections - while protecting ‘good’ microbes
Lozenges supplemented with liquorice root extract could be an effective remedy against upper respiratory tract infections while protecting microbes that are beneficial to the body, reveals a study presented at MLS Future Forum, which is supported by Applied Microbiology International.

NewsCommercial water dispenser machines may contain more contamination than tap water
Water dispenser machines in commercial spaces may contain higher levels of microbial contamination if they aren’t cleaned regularly compared to the tap water sources supplying them that contain residual chlorine, according to a new study.

NewsA CRISPR fingerprint of pathogenic Candida auris fungi
Precision diagnostic platform integrating CRISPR and single molecule technology with AI enables rapid and accurate detection of drug-resistant Candida auris pathogens.

NewsA bacterial toxin can counteract colorectal cancer growth
A toxin secreted by cholera bacteria can inhibit the growth of colorectal cancer without causing any measurable damage to the body. Systemic administration of the purified bacterial substance changes the immune microenvironment in tumours.

NewsA new study reveals how cholera virulence is activated
A new study provides a long-sought structural explanation of the regulatory cascade that allows Vibrio cholerae to colonize the human gut and produce the cholera toxin that causes life-threatening diarrhea.
