Joe Palca and Susie Neilson report on a phone-sized device that can test for cholera in 30 minutes. It’s the work of Katherine Clayton and colleagues at Purdue University.
Still early days; more field tests are planned.
[Clayton] knows making a cholera test doesn’t put her on a fast track for financial success.
Instead, she says, her background in engineering has made her feel a sense of obligation to help find solutions to global problems: “That’s what I enjoy — knowing what the future could look like.”
