Can Wearable Health Monitors Predict COVID-19?
/in Memos/by Chet ZelaskoAs of this writing, there are a minimum of five studies in the U.S. to determine whether wearable health-and-fitness monitors can predict the COVID-19 infection before noticeable symptoms actually occur.

Dental Cavities Are an Engineering Wonder
/in Memos/by Chet ZelaskoContinuing our look at the process of dental decay, the methodology for this study was complex to say the least: preserving the plaque, analyzing the structure, obtaining samples of the bacteria, attempting and succeeding to grow the structures on enamel surfaces that mimic teeth, getting photographs of the electronic polymeric structure, and more.
