Scientists believe they've discovered a new antibiotic called teixobactin that could turn the tide against the rise of drug-resistant bacteria, or superbugs.
Researchers from Northeastern University grew it in its native dirt rather than in a lab dish and it has cured mice in the lab.
Antibiotic resistance causes two million infections and 23,000 deaths in the United States each year.
A recent report warned that superbugs could kill up to 10 million people a year by 2050. The last major antibiotic was discovered in the 1980s.
