University of California, Irvine researchers said they have developed a way to digitally track the spread of the coronavirus, providing a means to keep track of the COVID-19 pandemic and aiding the reopening the state’s economy. TrackCOVID is a free open-source smart phone app ….. “It’s completely voluntary, said lead author Tyler Yasaka, a software engineer and junior specialist in otolaryngology at the UCI School of Medicine.

Often admired for their flawless appearance to the naked eye, crystals can have defects at the nanometer scale, and these imperfections may affect the thermal and heat transport properties of crystalline materials used in a variety of high-technology devices. Employing newly developed electron microscopy techniques, researchers at the University of California, Irvine and other institutions have, for the first time, measured the spectra of phonons – quantum mechanical vibrations in a lattice – at individual crystalline faults, and they discovered the propagation of phonons near the flaws.

Aditi Sharma, a resident physician in the UC Irvine Health dermatology department, said the sterilization wraps can be used in masks that filter up to 87% of particles, which is almost as effective as N95 masks, which have a filtration efficiency of 95%. … To design the mask, the physicians received help from several of the engineering groups on the UCI campus, including the Michelle Khine lab, Elliot Hui lab, and the Ben Dolan lab. UCI medical students have also helped cut wire for the masks.
