NewsEvolutionary model for antibiotic resistance reveals dose timing critical to care
The study that uses a “fitness seascape” to incorporate a patient’s dosage schedule into models that predict whether an infection will develop antibiotic resistance has found that inconsistent timing and missing early doses can lead to treatment failure.

NewsMicrobiome stability shapes how corals withstand extreme heat
A new study reveals why some corals resist bleaching while others don’t: the answer lies in a complex partnership between corals and their microbial allies, shaped by the history of the waters they inhabit.

NewsScientists develop a treatment platform to disable the ‘biofilm’ shield of superbugs
Researchers have developed a platform that utilizes microbubbles to deliver gene-targeted nanoparticles capable of breaking down MRSA biofilms, offering an innovative solution for treating infections resistant to conventional antibiotics.

NewsVaccinated patients hospitalized with COVID-linked acute kidney injury less likely to need dialysis after discharge
Vaccinated patients hospitalized with COVID-19 who developed acute kidney injury had better outcomes than unvaccinated patients with the same condition, new research suggests. The study found vaccinated patients were less likely to stay on dialysis after discharge, and more likely to survive, than unvaccinated patients.

NewsWhen bacteria get hungry, they kill – and eat – their neighbors
Scientists have discovered a gruesome microbial survival strategy: when food is scarce, some bacteria kill and consume their neighbors. The researchers show that under nutrient-limited conditions, bacteria use a specialized weapon — the Type VI Secretion System (T6SS) — to attack, kill, and slowly absorb nutrients from other bacterial cells.

NewsIs your gut microbiome a calorie ‘super harvester’?
A little-known microbe makes methane in your gut — and may help you get more calories from food, according to a new study. Researchers found that people whose gut microbiomes produce a lot of methane are especially good at unlocking extra energy from a high-fiber diet.

NewsStudy indicates that severe forms of COVID-19 infection in children may increase cardiovascular disease risks
Scientists analysed blood samples from 147 children across different COVID-19 conditions and identified significant metabolic disruptions beyond the acute viral infection phase. These alterations affect how the body processes fats (triglycerides and cholesterol) critical to healthy heart structure.

NewsHPV drives tumor development in rare nasal cancers
Human papillomavirus (HPV) can drive tumor development in some rare sinonasal squamous cell carcinomas (SNSCCs), according to a new comprehensive study of these tumors from investigators who also identified common mutations among these cancers and a potential combination treatment.

NewsNew research reveals a deadly fungal pathogen’s vulnerabilities
Scientists have disovered how the lethal pathogenic fungus, Cryptococcus neoformans, thrives, allowing them to identify potential novel therapeutic targets for treatment.

NewsA repurposed FDA-approved drug shows promise in killing antibiotic resistant bacteria
A study of Acinetobacter baumannii employed an entirely new strategy to identify weaknesses specific to resistant bacteria and then target these weaknesses with an alternate drug. They found that fendiline kills the bacterium by targeting the essential lipoprotein trafficking pathway, which is weakened in antibiotic resistant bacteria.

NewsSHEA affirms trust in ACIP and supports science-based vaccine policy
Public health experts have commented on the removal by the US Department of Health and Human Services (HHS) of all 17 members of the Advisory Committee on Immunization Practices (ACIP), which advises the Centers for Disease Control and Prevention (CDC) on the use of vaccines in the US.

NewsPeople with COVID-like symptoms took up to nine months post-infection to regain mental well-being
New research finds that people with COVID-like symptoms returned to optimal physical well-being an average of three months after infection, but took up to nine months to return to top mental well-being.

NewsNature’s toolkit: Scientists breed mushrooms to build versatile natural substitutes for commonly used materials
Scientists have shown that natural genetic variations in a common species of mushroom can be used to create new strains capable of making customized, biodegradable replacements for fabric, plastic, packaging and other environmentally harmful materials.

NewsInfectious diseases experts raise alarm about antifungal resistance, call for global effort
Infectious disease experts are raising the alarm about the role new pesticides can play in building resistance to antifungal medical treatments, calling for a coordinated, global ”One Health” approach to developing, testing and using agents to fight pathogens.

NewsEndangered mountain caribou possess unique gut microbiome that may be important for recovery efforts
Endangered mountain caribou in British Columbia possess a unique gut microbiome in late winter when they feed on tree lichens, a finding that could guide caribou recovery efforts, according to a new study.

NewsFish ‘beauty salons’ offer insight into how microbes move within reefs
A new study highlights the potential impact of cleaner fish in coral reefs and the need to demystify their role in shaping reef microbial diversity and transmission.

NewsCoral Art: Drawing out the secrets of coral reef resilience to high ocean temperatures
A researcher uses her art to explain how corals from more variable ocean environments may be better equipped to survive rising ocean temperatures than corals from more stable environments.

NewsScientists discover 230 new giant viruses that shape ocean life and health
Using high-performance computing methods, researchers have identified 230 novel giant viruses in publicly available marine metagenomic datasets and characterized their functions.

NewsCritical step in COVID viral infection identified
Researchers have uncovered a mechanism that SARS-CoV-2, the virus that causes COVID-19, uses to protect itself inside the body as it works to replicate and infect more cells. Without this protective mechanism, viral infection is dramatically reduced.

NewsResearch identifies new trigger accelerating antibiotic resistance
A new study shows that ciprofloxacin, a staple treatment for urinary tract infections, throws Escherichia coli (E. coli) into an energy crisis that saves many cells from death and speeds the evolution of full‑blown resistance.
