Living antibiotics - they're deadly to superbugs. It’s no secret that the world is facing an antibiotics apocalypse; a world in which these lifesaving antibacterial medicines no longer work.

Living antibiotics - they're deadly to superbugs

For too many years, we've overused antibiotics. It's been going on everywhere: in agriculture, because, among other things, they help us breed bigger animals; in medicine, to treat infections that may have cleared up on their own; or for viral infections, such as colds and flus, that antibiotics don’t help with at all.

The result has been a sort of antimicrobial resistance movement, culminating in the emergence of drug-resistant bacteria strong enough to kill. Other issues, too, have contributed to the rise of antibiotic-resistant bugs. Poor hygiene in hospitals, for instance, help to spread infections, and a lack of new types of antibiotics has left us helpless in the face of resistant bacteria.

Paperfuge: 20-cent, toy-inspired tool helps diagnose disease

Today, diagnostics rely heavily on centrifuges, machines with rapidly rotating containers that separate fluids of different densities through centrifugal force. Manu Prakash, assistant professor of bioengineering at Stanford University, credits his fascination with toys and his experience growing up in India, where he didn't have access to the scientific tools he needed, to drawing a comparison between the two. Centrifuges can help isolate and detect low levels of infection, pathogens and parasites in blood, urine and stool samples. But due to their high cost -- upward of a thousand dollars per machine in some cases -- they aren't always available where they are needed most.
