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.
