NewsStiff gels slow germs: New study maps hydrogel properties that control bacterial growth
Scientists has found that firmer, lower water content hydrogels limit bacterial growth, with implications for designing antibacterial coatings, infection models, and advanced medical materials.

NewsResearchers solve mystery behind rare clotting after adenoviral vaccines or natural adenovirus infection
Scientists have uncovered why a small number of people developed dangerous blood clots after either receiving certain COVID‑19 vaccines or experiencing a natural adenovirus infection - the answer lies in an unexpected case of misdirected targeting by the immune system.

NewsRoot microbes could help oak trees adapt to drought
Microbes could help oak trees cope with environmental change. A study observing oaks growing in a natural woodland found that the trees’ above- and below-ground microbiomes were resilient to drought, nutrient scarcity, and exposure to pathogenic beetles and bacteria.

NewsVirus-based therapy boosts anti-cancer immune responses to brain cancer
A study has shown that a single injection of an oncolytic virus—a genetically modified virus that selectively infects and destroys cancer cells—can recruit immune cells to penetrate and persist deep within brain tumors.

NewsHow food shortages reprogram the immune system’s response to infection
When food is scarce, stress hormones direct the immune system to operate in “low power” mode to preserve immune function while conserving energy. This reconfiguration is crucial to combating infections amid food insecurity.

NewsAvian malaria widespread across Hawaiʻi bird communities, new study finds
A new study shows that avian malaria can be transmitted by nearly all forest bird species in Hawaiʻi, helping explain why the disease is present almost everywhere mosquitoes are found across the islands.

NewsBacterial hitchhikers can give their hosts super strength
Molecular hitchhikers living within bacteria can make their hosts extra resistant to medical treatment by corralling them into tightly packed groups. The study introduces a previously unknown avenue through which bacterial infections can become more difficult to treat.

NewsShorter treatment regimens are safe options for preventing active tuberculosis
A study comparing one- and three-month antibiotic treatments to prevent active tuberculosis (TB) finds that a high percentage of patients successfully completed both regimens and suffered few adverse side effects.
-
NewsUS study finds declining perception of safety of COVID-19, flu, and MMR vaccines
A sizable majority of Americans think the three vaccines that combat potentially deadly illnesses flu, Covid-19 and measles are safe to take, although perceptions of the safety of all three vaccines showed a statistically significant drop over the past three years.

NewsGenotype-specific response to 144-week entecavir therapy for HBeAg-positive chronic hepatitis B
HBV genotype B demonstrates superior histological responses to ETV therapy compared with genotype C, supporting the clinical value of HBV genotyping for personalized CHB management. These findings highlight the importance of considering viral genotype when evaluating treatment outcomes.

NewsResearchers identify strategies for preventing the most infectious strains of S. aureus in the NICU
A new study has identified which strains of Staphylococcus aureus – commonly known as staph – are commonly transmitted in neonatal intensive care units and which specific strains are most likely to cause invasive and serious infections.
-
NewsResearchers rebuild microscopic circadian clock that can control genes
Researchers have solved how the circadian clocks within microscopic bacteria are able to precisely control when different genes are turned on and off during the 24-hour cycle.
-
NewsStudy reveals how chills develop and support the body’s defense against infection
Researchers in Japan have identified the neural mechanism behind chills and the instinct to increase body temperature during infection.

NewsLong COVID linked to Alzheimer’s disease mechanisms
The increased size of, and lesser blood supply to, a key brain structure in patients with Long COVID tracks with known blood markers of Alzheimer’s disease and greater levels of dementia, a new study finds.
-
NewsDeep-sea microbes get unexpected energy boost
A study shows that sinking organic particles—known as marine snow—begin to leak dissolved carbon and nitrogen when they reach depths of 2–6 kilometres, presenting microbes in the surrounding seawater with nutrients. The leakage is caused by the intense hydrostatic pressure in the deep ocean.

NewsAccomplices in the spotlight: When the interaction between fungi and bacteria becomes a dangerous alliance
Researchers discover new co-infection strategies of Candida albicans and Enterococcus faecalis. Only some E. faecalis strains significantly increased cell damage when infected simultaneously with Candida albicans. These strains produced cytolysin, a toxin that perforates cell membranes and kills the cells.

NewsAntibiotic-resistant bacteria found in many healthy birthing mothers and their newborns
A recent study found gut bacteria resistant to common antibiotics in a sizable percentage of healthy birthing mothers and their newborns. In this study, 38% of bacterial strains resistant to ceftriaxone transmitted from mother to infant were E. coli.

News‘Hidden’ bugs in our gut appear key to good health, finds global study
A single group of bacteria has repeatedly shown up in high numbers in the gut microbiomes of healthy people. Scientists found the level of CAG-170 bacteria present was consistently higher in healthy people than those with diseases including inflammatory bowel disease, obesity and chronic fatigue syndrome.
-
NewsMicrobiomes interconnect on a planetary-scale, new study finds
Scientists reveal that microbes living in similar habitats are more alike than those simply inhabiting the same geographical region. By analysing tens of thousands of metagenomes, they found that while most microbes adapt to a specific ecosystem, generalists can thrive across very different habitats.

NewsTexas-grown cabbage meets global tradition in kimchi research
Researchers are turning Texan produce into kimchi as part of a study that links fermentation science, food safety and new market opportunities for U.S. farmers. The research examines how Texas-grown cabbage and other leafy greens perform during kimchi fermentation.
