I'm amazed by the power of antibiotics, but I'm also aware that bacteria are becoming resistant to them. So it's great to hear that scientists in Boston have isolated a new class of antibiotic that bacteria aren't resistant to yet.
The team used tiny compartments buried in soil to grow bacteria that can't survive in normal Petri dishes. One bacterium makes a compound that kills dangerous bacteria such as MRSA. This method could unlock many more new antibiotics - and it makes me hopeful about fighting diseases in the future.
