New biosensor rapidly detects deadly foodborne pathogen
...h occurs when a sample believed to be contaminated grows for a period of time in a nutrient broth to allow any pathogen cells present to multiply. The enrichment process increases the concentration of cells present, making it possible for today's sensors to detect their presence, but it can tak...Rice engineer wins prestigious Annunzio Award

...contaminants, are in these concentrations. Nothing grows in these areas." "So, we knew the metals are there, but we have not known where they reside in the streams and soils," said Hochella. "Is the lead associated with other minerals or with biological material, or is it in a separate phase? No one knew."......zes.
