Increasing the rate at which we develop new drugs is a good way to tackle multidrug resistance. But there is another strategy that is inherently better, say researchers
Intelligent dust particles embedded in the brain could form an entirely new form of brain-machine interface, say engineers
Thinking about cancer as an ecosystem is giving biologists access to a new armoury of mathematical tools for tackling it, such as evolutionary game theory
