NewsOne strategy to block both drug-resistant bacteria and influenza: new broad-spectrum infection prevention approach validated
A new paper moves beyond traditional infection control strategies reliant on antibiotics and vaccines by introducing a new approach that primes the immune system before infection occurs.

NewsHIV antibody opens up new approaches for vaccine development and combination therapies
An international research team has identified a novel HIV antibody that targets the virus at a particularly vulnerable site and overcomes previous limitations of known antibodies. The study opens up new perspectives for the development of vaccines and therapeutics against HIV-1.

NewsEleven genetic variants affect the gut microbiome
In two new studies on 28,000 individuals, researchers are able to show that genetic variants in 11 regions of the human genome have a clear influence on which bacteria are in the gut and what they do there. Only two genetic regions were previously known.

NewsRecycling strategies of fungi can affect how forests store carbon
Some fungi are wasteful, while others recycle – and this can determine how much carbon is stored in a forest. Researchers have revealed how fungi manage their mycelium, the network that builds the structure of fungus. The results could provide new insights into the carbon cycle and climate.

NewsBasic research on Listeria bacteria leads to unique cancer therapy
After nearly 40 years of research on how After nearly 40 years of research on how Listeria bacteria manipulate our cells and battle our immune system to cause listeriosis, researchers have discovered a way to turn the bacteria into a potent booster of the immune system — and a potential weapon against cancer.

NewsChildren with Crohn’s have distinct gut bacteria from kids with other digestive disorders
Researchers have found a “microbial signature” of pediatric Crohn’s disease that differs from the makeup of gut bacteria in children with other gastrointestinal conditions, with Crohn’s patients harboring more pro-inflammatory bacteria and less protective bacteria.
-
NewsManagement practices can enhance soil microbiome functions in plant defense
Researchers analyzed surveys and soil samples from 85 organic farmers in New York to investigate the interaction between beliefs, management practices, and soil microbiome functions.

NewsBack from blight: Genomics offers a faster path to restoring the American chestnut
After more than a century of devastation from deadly blight, the iconic American chestnut tree could be brought back from the brink of extinction thanks to novel genomic tools and carefully bred hybrids, a new study finds.

NewsWhat drives a mysterious sodium pump?
The enzyme Na⁺-NQR is a sodium pump that drives the respiration of many marine and pathogenic bacteria, powering the transportation of sodium ions across the membrane. A new study found that the sodium pump changes its structure in response to electron transfer inside the protein.

NewsSeashells and coconut char: A coastal recipe for super-compost
Researchers have developed a calcium-modified biochar that speeds up waste recycling and creates nutrient-rich soil, boosting specialized microbial communities that break down tough materials like lignin and convert them into stable humus.
-
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.
