A new study is the first to map changes to specific gut bacteria based on interactions between human microbes and insect-killing chemicals observed in the lab and an animal model. The analysis showed that over a dozen pesticides influence human gut bacteria growth patterns, affect how gut microorganisms process nutrients and camp out inside some bacteria. Experiments in mice showed that one gut bacteria species provides some protection against pesticide toxicity, hinting at the possibility for a probiotic approach to preventing some of their damaging health effects.
Researchers at ETH Zurich have developed a human model of lactating breast tissue using 3D printing and breast milk cells.
The cells in the tissue model produced components of human milk.
The model is designed to help better understand the processes involved in lactation.
