Alexander Fleming's work has helped countless people over the last nine decades.

It's not a matter of if, but when, the next deadly pandemic will strike. Will the world be ready?
The truth about cats and dogs.
Farm animals are the subject of WHO initiatives around antibiotics, but domestic pets could actually be a bigger risk.
Antibiotic-resistant bacteria inside a biofilm.
Triclosan, an ingredient in soap and many household cleansers, has gained a bad reputation. A recent study looking for a way to boost an antibiotic, however, found that tricloscan did a great job.
Clostridium difficile bacteria causes diarrhea and inflammation of the colon.

A new type of antibiotic uses DNA to fight a common deadly microbe, Clostridium difficile. These new drugs are inexpensive and adaptable and can be modified to target any bacterium, lowering the chance of drug resistance.
Getting rid of this scourge is nothing to be sneezed at.
Cattle that are grass-fed, antibiotic- and growth hormone-free gather at a farm in Oregon in 2015. There’s a debate over whether antibiotic use in livestock makes germs more resistant to the drugs, and results in infections being passed on to humans who consume the meat.

The use of antibiotics in raising livestock is complex. We could be moving towards a less-than-ideal result due to poor understanding, over-simplistic messaging and a rush for competitive advantage.
Bacteria in the dish on the left are sensitive to antibiotics in the paper discs. The ones on the right are resistant to four of the seven antibiotics.

Antibiotic-munching microbes may prove useful for mopping up contaminated water supplies and land.
The problem of antimicrobial resistance won't go away as long as people in poor countries don't have access to clean water.

New research shows just 1% of E. coli bacteria's genetic mutations are lethal.
Antibiotic resistance is not new but recent developments increase the urgency for action.
Superbugs used to pose the greatest risk to people with compromised immune systems and those who had surgery. But their sexual transmission means antibiotic resistance can spread much more widely.
High-tech ways to scan nature’s own creations.
Pharmaceutical companies focus on small molecules they've devised – and can easily patent. But nature's already come up with many antibacterial compounds that drug designers could use to make medicines.
A giant ant carries a dead fellow in the name of cleanliness.
Ants produce their own antimicrobial chemicals to fight bacteria.
Potting mix is known to carry harmful bacteria and fungi.

The risk of bacterial or fungal infection from potting mix is very low. Wearing gloves and washing your hands will keep it even lower.
Pills and ills.
Antimicrobial stewardship is proving effective, but we're not fully across what is happening.
Bacteria don't just mutate to beat antibiotics, they also make changes on the fly.
India's laissez-faire attitude to drug regulation is a serious threat to global efforts to tackle antimicrobial resistance.
Some patients may be prescribed antibiotics as preventatives, rather than to treat infections.
We know overuse and inappropriate use of antibiotics contribute to resistance, so it's important we develop strategies to improve practice.
Sure it tastes nice, but what else can it do?
Manuka honey has a lot of evidence-based benefits, and a lot of rubbish claims too.
Plants make proteins based on whatever genetic material you give them.
Carl Davies, CSIRO
Inserting a random DNA mishmash into a plant or bacterium directs it to make a novel protein. Sifting through the resulting molecules, researchers may find ones have medical or agricultural uses.
