For some illnesses, shorter courses of antibiotics work just as well as longer ones, but researchers are still working out the ideal timescales for many infections – and it may not line up with when you feel better.

Microbial ecology helps explain how ecosystems respond to environmental pressures.
An expert answers questions on superbugs, from overuse in farming to whether resistance is really an unwinnable arms race.
Scientists are using AI and physics-based simulations together to design new peptides that will kill previously drug-resistant bacteria.
The source was a newly discovered bacterium called Legionella pneumophila that can thrive in household pipes, whirlpools, cooling units and outdoor fountains.
When people harness the logic of natural selection, they can often find efficient and effective ways to solve complex problems.
As antibiotic resistance grows, scientists are turning to bacteriophages, viruses that target harmful bacteria without wiping out beneficial microbes.
The drugs that transformed medicine are losing their power, raising fears of a post-antibiotic era in which common infections kill.
Bacteria don’t quietly die when exposed to antibiotics – they actively respond in ways that in turn change how your body responds to infection.
Antibiotic prescribing around the time of surgery and in aged care isn’t always appropriate, a new report shows. Here’s what else we learned.
Five-thousand-year-old microbes reveal nature’s antibiotic arms race, and hold clues to both the threat of drug resistance and the cure.
Many countries’ guidelines are unclear, lacking – or even nonexistent.
Antibiotics transformed health care for the better, but their diminishing effectiveness may soon be its undoing. Researchers are studying ways to fight back against resistance.
The disinfectants we trust to protect us from microbes may also inadvertently help those microbes evolve to become more resistant to them.
Every flush sends traces of our medicines into rivers. When antibiotics mix with common drugs like painkillers or hormones, bacteria can evolve to resist treatment.
Most antibiotic resistance research comes from high-income countries but the greatest threats are elsewhere. This inequality is shaping the future of global health.
This is a significant scientific development, but several hurdles remain before we might see these antibiotics available for use.
Over-subscription of a topical antibiotic likely led to the emergence of a superbug which is now the leading cause of resistant infections.
As many as 1 in 5 Americans believe they have a penicillin allergy, but just a tiny fraction actually do. In recent years, it’s gotten a lot easier to find out.
The viruses that kill bacteria may be our best bet against antibiotic resistance – if we can understand how they win.
