Yeast-Powered Bee Nutrition Boost! 🐝

Engineered yeast produces essential sterols missing from pollen substitutes, enabling honeybees to rear brood without floral pollen. This could address pollinator decline and food security challenges.

Cross-membrane cooperation among bacteria can facilitate intracellular pathogenesis - Nature Communications The pathogenic bacterium Pseudomonas aeruginosa can be found in vacuoles and cytoplasm within infected cells. Here, Schator et al. show that extracellular bacteria use a type-III secretion system to i...

Paper alert 🚨🚨
In this study we explore the effects of cross-membrane cooperation of extra- and intracellular bacteria during infection in vitro and in vivo.

Key conclusion: We should be more like bacteria, because cooperation is king (or queen)!

Deep learning reveals antibiotics in the archaeal proteome - Nature Microbiology Use of artificial intelligence to mine proteomes of archaea led to the discovery of archaeasins, antimicrobials that kill drug-resistant bacteria in laboratory and animal models, offering a promising ...

(1/5)For over a century, the hunt for new antibiotics has focused almost exclusively on bacteria and fungi. Today, that paradigm shifts. By coupling state-of-the-art AI with the vast, largely uncharted diversity of Archaea, we open a new frontier for molecular discovery.

FEMS MICRO Milan 2025 is off to a great start with Prof. Carmen Buchrieser presenting her keynote on Legionella pneumophila and the fascinating ways this pathogen mimics eukaryotic cells.

Cancer DNA is detectable in blood years before diagnosis Tiny, newly formed tumors shed small fragments of DNA that are swept into the bloodstream. Future cancer screening tests could detect them early.

It’s possible to spot tumor DNA more than three years before a person is diagnosed with cancer.

Hunting for these telltale traces using highly sensitive and accurate technology could be a powerful tool in early cancer screening efforts.

Cell-cell communication via sound waves. Energy dissipation and cell's vibrational response as a result of sound communication enables the coordinately dissipation of the energy of the cells. A coherent collective vibrational mode (right) is reached when all the cells are 'in tune,' which could amplify the signal. Adapted from https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3057284/
