Bill Gates Is Building A Machine To Diagnose Nasty Diseases

The Bill & Melinda Gates Foundation is celebrating 10 years of its Grand Challenges in Global Health program, where it asks scientists to brainstorm solutions to gnarly health problems and then offers grants to the best ideas.

Through his foundation, Gates has ventured into areas that others would shun, such as new kinds of toilets, batteries that run on human urine, more-enjoyable condoms that offer better protection against sexually transmitted disease.

On Thursday, he gave an update on a new challenge: “Can you create a new device that quickly diagnoses HIV, TB, malaria, and other diseases… accepts different samples, like blood, saliva, and sputum… is affordable… and reliable… and will work in a small clinic that has only a few hours of electricity a day?” he wrote in a blog post.

Sounds like something akin to a “Star Trek” tricorder, the handheld device from the sci-fi TV show that analysed the world. But there’s already a $US10 million X Prize challenge for that sponsored by Qualcomm. (That grand prize will be awarded in 2016.)

Gates shared a picture of the kind of device his scientists are working on, and it looks kind of like a 3D printer. You slip the samples into it and out pops an diagnosis on a screen.

There are five teams working on the challenge, he says. This device pictured below is from a Seattle-based health R&D company called Stratos.

“Today we know that it’s technically possible to build a device and that there are partners ready to help,” he says.

But he knows that’s not enough. There are questions such as if these machines can be made affordably enough and if it will do any good to diagnose people in areas where medical treatment is scarce.

But it is Gates’ attitude toward the challenge that is also inspiring.

“If this idea succeeds, that will be fantastic. If it doesn’t, we’ll all be disappointed,” he writes. “If one avenue turns out to be a dead end, there are always many more waiting to be explored.”

That’s just plain good advice for anyone trying to do anything hard in life.
