Carbon-fixing materials — substances powered by the sun that use atmospheric carbon dioxide to grow and repair themselves, just as plants do — don’t yet exist outside the lab. But scientists are getting tantalizingly close to making them a commercial reality.

Researchers from Washington State University have come up with a diagnostic rig that can use a smartphone, a prism, and an ELISA plate to detect cancer. In the controlled settings of their lab, with the high-purity reagents they had to work with, the researchers were able to detect the cancer marker interleukin-6 (IL-6) with 99% accuracy.
Obviously results in the field will not reflect the near-ideal conditions of lab work. The concepts, though, are solid. The rig consists of a back lit ELISA assaying plate with 96 wells, a “micro-prism array,” and a 3D printed cradle that holds a smartphone with a camera. The diagnostician using the rig would take samples from a patient, put them in the assay plate, and turn on the back-light.

“Factory resetting” a device often does not prevent later users from recovering your files that were previously stored on it. Here’s what you need to know.
Are you planning to upgrade your smartphone, to sell your old device, or to give it to a child or friend?
Were you planning to “factory reset” your device to clean out all your data?
Unfortunately, in many cases, “factory resetting” a device does not stop later users from accessing your data. Continue reading How to Securely Wipe Your Smartphone’s Data
