Several bacteria counting techniques already exist. However, these approaches are slow and sensitive to laboratory conditions. Sam Nugen and his team from Cornell University are streamlining this process using a type of virus called phages, … Continue reading Viruses to the Rescue: Can we use viruses to find bacteria in our environment?
