A new COVID-19 test could be a lot simpler. “The idea is to have a paper-based system where people can just look at it and say, yes, you have it, or not.”

Engineers are solving problems with testing and treatment for COVID-19, including designing new medical equipment and better nasal swabs.

Though it's yet to be validated or approved by the FDA, a new potential test for COVID-19 could deliver results in less than 10 minutes.

"If we can [get a] result faster, that also protects our friends and loved ones... who are going into the clinic. My best friends are going to war."

It may one day be possible to detect prostate cancer from a simple, non-invasive urine test

If you've ever had a mammogram or an MRI you know how uncomfortable the tests can be. New stretchable, wearable RF coils could change that.

A new "scorecard" that looks at 29 different genes could be a tool to improve cancer diagnosis. It may also help predict patient survivability.

When tested with people with easy-to-access veins, a blood-drawing robot had a 97% success rate. That's just as good and even better than phlebotomists.

Using magnetic levitation to split up different proteins in blood plasma could be a way to diagnose opioids or even cancer.
