Legumes like soybeans, alfalfa, peas, beans, peanuts and many more have a remarkable ability: They can partner with soil bacteria called rhizobia to capture nitrogen from the air in a biological ...

For decades, peering into the gut meant invasive procedures and partial answers. Now, scientists are developing a biosensor that could reveal a far more expansive picture of what’s really happening ...

Genes in many bacteria are rich in purine nucleotides (A and G), but the origin of this preference is unclear. Here, using a large-scale reporter assay in Bacillus subtilis, we show that this purine ...

Scientists studying thousands of rats discovered that gut bacteria are shaped by both personal genetics and the genetics of social partners. Some genes promote certain microbes that can spread between ...
