NewsStarvation triggers reversible epigenetic changes in fish pathogen
What happens to a bacterial pathogen when food runs out—for several months? A new study reveals that Flavobacterium columnare, a deadly aquatic pathogen responsible for columnaris disease in fish, does not change its DNA sequence during prolonged starvation. Instead, it remodels its epigenetic landscape.

NewsPrecigen presents new long-term durability data for PAPZIMEOS, recently granted seven-year market exclusivity
Precigen, Inc. has announced updated long-term follow-up data from the pivotal study of PAPZIMEOS™ (zopapogene imadenovec-drba) for the treatment of adults with recurrent respiratory papillomatosis (RRP).

NewsNew analysis confirms benefits of childhood flu vaccines
Pediatric flu vaccines significantly reduce the number of childhood cases of influenza, new research confirms. The findings show that for every 100 children vaccinated, between nine and 14 fewer children catch the flu.

NewsProtection for newborns: New treatment aims to prevent meningitis without antibiotics
One of the leading pathogens responsible for meningitis cases in newborn babies is the K1 form of the E. coli bacterium. Now, researchers have developed a triple-pronged approach that seeks to prevent transmission to newborns.

NewsNew study suggests fish gut microbe helps regulate ocean health
New research reveals a potential link between the gut microbes of a fish and global ocean processes, offering new insight into how marine ecosystems help regulate ocean chemistry and the marine carbon cycle.

NewsScientists clarify the interplay between host and gut microbiota in selenium metabolism
In a recent study, researchers used rats to investigate how gut microbiota and the host jointly manage selenium metabolism. They found that gut microbiota actively transform selenium into various metabolites that influence selenium utilization, detoxification, and excretion, and that the host’s selenium intake affects bacterial diversity.

NewsResearch shows plants such as canola, tomatoes and rice reduce iron uptake when stressed by drought
New research has found that plants, ranging from canola to rice to tomatoes, actively shut down their own ability to take up iron when they experience drought. The study questions whether plants send out a ‘cry for help’ when they are stressed by drought to recruit beneficial soil microbes in their roots.

NewsResearchers discover tick protein that may block disease transmission
Researchers have found that ticks produce an exosomal glycine-rich protein that plays a vital role in helping ticks feed and transmit viruses. When they used genetic tools to silence the gene responsible for this protein, ticks lacking the protein struggled to feed effectively and showed reduced body weight after feeding.

NewsProtective soybean seed fungicide treatment may not increase profitability
Researchers analyzed how seed treatments affect yield and profitability in soybean farms in the Midwest and found that yield gains were modest and often did not offset the added cost of the treatment. Additionally, financial benefit was likely only when seed treatment costs were low and soybean prices were high.

NewsHealth researchers call for support to develop pandemic prevention
The Vanderbilt Center for Antibody Therapeutics has received large-scale government grants and contracts to fund the discovery of human antiviral antibodies. The problem is the next step — finding corporate partners to develop the antibodies through human testing.

NewsSkin-to-skin care may save newborn lives
Kangaroo mother care, first introduced as an alternative to insufficient incubator care, combines skin-to-skin contact, exclusive breastfeeding, early discharge, and follow-up support. A new review case makes the case for treating iKMC not as an optional add-on, but as a core part of neonatal care for eligible preterm and low-birth-weight infants.

NewsSoil scientist awarded $1.6 million NSF grant to study ‘living skin’ of arid ecosystems
A soil scientist has received a $1.6 million, five-year grant from the U.S. National Science Foundation (NSF) to fund her team’s study of how increasing temperature fluctuations impact the biocrust microbiome — the complex, thin-layer microbe community that stabilizes soil, fixes nitrogen and drives nutrient cycling in drylands.

NewsResearchers aim to improve access to high-quality research and biomanufacturing tools in resource-limited settings
Researchers have demonstrated the effectiveness of a suite of low-cost, portable biotechnology tools designed to improve access to laboratory research and diagnostics in resource-limited settings.

NewsScientists turn microalgae waste into high-performance membranes for cleaner municipal wastewater
A new study reports a sustainable membrane technology that converts microalgae-derived biochar into an advanced material for municipal wastewater treatment, offering a promising route to cleaner water and waste valorization.

NewsNot all biochar is equal: New perspective calls for clearer claims in carbon removal and soil health
A new perspective warns that biochar’s long-term carbon storage potential and its soil improvement benefits should not be treated as the same thing. Clearer communication is urgently needed as biochar becomes a major player in voluntary carbon markets and climate mitigation strategies.

NewsVote now! Record number of candidates vie in AMI Trustee election
It’s time to have your say! Applied Microbiology International (AMI) is calling on all members to vote in the Trustee election after receiving record nominations.

NewsRecent study reveals how bacteria capture a rare type of sugar molecule
Researchers have identified a novel transport protein that binds cyclic β-1,2-glucans, revealing unexpected diversity in bacterial sugar uptake mechanisms.

NewsNovel therapeutic drug for tuberculosis is proposed using high-precision molecular simulation
Researchers have proposed a novel therapeutic agent for tuberculosis, using high-precision molecular simulation techniques. The proposed drug is anticipated to bind strongly to the drug-metabolizing enzyme cytochrome P450 (CYP).

NewsNew antibiotic design could help treat drug-resistant infections
A new study has shown that antibiotics can be chemically redesigned so they are less easily removed by efflux pumps. This allows the antibiotic to remain inside the bacterial cell at higher concentrations, restoring its ability to kill bacteria even when resistance mechanisms are present.

NewsExperts convened by WHO advise on candidate treatments and vaccines for Ebola disease caused by Bundibugyo virus
In response to the current outbreak of Ebola disease caused by Bundibugyo virus, WHO convened several of its expert and advisory groups to assess potential vaccines and therapeutics for both prevention and treatment of Bundibugyo virus disease (BVD).
