NewsStudy identifies viruses in red tide blooms for the first time
A new study identifies viruses associated with Karenia brevis, the single-celled organism that causes red tide. By testing water samples collected from red tide blooms, the researchers found several viruses in blooms — including one new viral species.

NewsNew study reveals high levels of fusarium mycotoxins in seized cannabis from Arizona and California
A recent study has uncovered alarming levels of Fusarium mycotoxins in illicit cannabis samples seized in Arizona and California. 16% of the 118 samples tested positive for harmful mycotoxins, posing potential health risks to consumers and highlighting the unregulated and dangerous nature of black-market cannabis.

NewsUnknown microorganisms used marble and limestone as a habitat
Research work has revealed unusual structures that are probably due to the activity of an unknown microbiological life form. Unusually small burrows, i.e., tiny tubes that run through the rock in a parallel arrangement from top to bottom, were discovered in marble and limestone of the desert areas of Namibia, Oman, and Saudi Arabia.

NewsTeam finds regional, age-related trends in exposure to drug-resistant pathogen
A study from 10 US states found drug-resistant Campylobacter jejuni infections were highest in the 20-39 age group and that quinolone-resistant C. jejuni infections increased from 22.6% of those tested in 2013 to 33.54% in 2019. It identified regional differences in C. jejuni resistance to quinolones and six other classes of antibiotics.

NewsStudy yields new data on Mpox vaccine effectiveness in people with HIV
A new study has found that a single dose of the Imvanex vaccine provides protection against Mpox with 84% effectiveness. For people with HIV, however, a single dose of the vaccine fails to offer sufficient protection. All at-risk groups, especially people with HIV, should receive the second dose of the vaccine as recommended.

NewsHost’s sex plays key role in how gut microbiome evolves with age
Researchers studied how aging affects gut bacteria in a special group of rats generated to have genetic diversity similar to humans. Their research found that both biological sex and mitochondrial DNA—the small set of genes inherited only from mothers—play a key role in how gut bacteria change over time.

NewsDigging into the world of plant-growth-promoting microbes
A team including members of AMI has provided a model illustrating how Pseudomonas bacteria can influence root development to promote growth and enhance the adaptation of plants under salinity stress.

NewsLeafcutter ants recognize and fight pathogen with social immunity
Various characteristics of social immune memory were observed in colonies of Atta sexdens (lemon leafcutter ants) exposed to different pathogenic fungi. Such information is useful for future development of appropriate pest control.

NewsPlastic-degrading enzymes from landfills
Researchers identified and analysed the structure and predicted functions of potential plastic-degrading enzymes in collected landfills sample from around the world, in an effort to reduce plastic pollution.

NewsFDA-approved dialysis drug may help fight against antimicrobial resistance
In account of the imminent threat of antimicrobial resistance (AMR), a study revealed that the FDA-approved sevelamer, which is used to treat chronic kidney disease undergoing dialysis, is successful in the removal of other off-target antibiotics (vancomycin and daptomycin) from the gut.

NewsRed coral colonies survive a decade after being transplanted in the Medes Islands
The red coral colonies that were transplanted a decade ago on the seabed of the Medes Islands have survived successfully. They are very similar to the original communities and have contributed to the recovery of the functioning of the coral reef.

NewsBacteria invade brain after implanting medical devices
Researchers have discovered that bacteria can invade the brain after a medical device is implanted, contributing to inflammation and reducing the device’s long-term effectiveness.

NewsScientists discover protein key to bacteria’s survival in extreme environments
A new discovery sheds light on how certain bacteria – including strains that cause food poisoning and anthrax – form spores for survival.

NewsNew ‘shy’ fungus found in old-growth forest
Although fungi of the genus Piloderma are common, scientists have now discovered five previously unknown species. One of these is one of the most widely distributed species in Northern Europe, while another is found only in old-growth forests.

NewsImmature platelet fraction offers clinical predictor for enhanced platelet recovery in patients with dengue fever
Immature platelet fraction (IPF) is recognized as a marker for thrombopoiesis, but a new study indicates that IPF% can be utilized as a predictor of platelet increase in patients with dengue infection.

NewsNewly identified bacterial protein helps design cancer drug delivery system
Researchers have identified a previously unknown bacterial protein, the unique structure of which acts as an actin homolog that can be used to design protein nanoparticles for the targeted delivery of anticancer drugs to tumors.
-
NewsResearchers demonstrate new technique for boosting plant growth with bacteria
A single combined delivery system incorporating multiple active ingredients, including plant growth-promoting bacteria and agrochemicals, is developed to ensure beneficial bacterial survival and improve plant growths.
