Researchers discovered that 168 common chemicals can disrupt the growth of beneficial gut bacteria, with some also promoting antibiotic resistance. Many of these substances—found in food, water, and household items—weren’t previously suspected of affecting living organisms. A new machine learning model now predicts which chemicals may harm the microbiome. The findings suggest safety testing must expand to consider gut health.

Nitrous oxide may offer quick, short-term relief for people with major depression, especially those who haven’t responded to standard medications. The meta-analysis found rapid improvements after a single dose and more sustained benefits after repeated treatments. Side effects were generally mild and brief, though researchers stress the need for larger, longer-term studies.

Scientists have found that common foods can contain hidden contaminants formed during cooking or through environmental exposure. A new testing method called QuEChERS helps identify these chemicals more quickly and with greater ease. The research showed strong accuracy and high sensitivity across multiple food samples. This streamlined approach could improve food safety checks while reducing chemical waste.
