The National Institute of Information and Communications Technology (NICT), Tohoku University, Toin University of Yokohama, and Japan Science and Technology Agency (JST) have succeeded in developing a scanless high-speed holographic fluorescence microscopy system with submicron resolution for a 3D space. The system is based on digital holography. The developed microscopy system has an algorithm to acquire 3D information of fluorescent objects toward scanless 3D measurement in less than 1 millisecond.

The Covid-19 pandemic has made home offices, virtual meetings and remote learning the norm, and it is likely here to stay. But are people paying attention in online meetings? Are students paying attention in virtual classrooms? Researchers Jens Madsen and Lucas C. Parra from City College of New York, demonstrate how eye tracking can be used to measure the level of attention online using standard web cameras, without the need to transfer any data from peoples computers, thus preserving privacy.

Which demographic and socioeconomic factors were associated with patient participation in telehealth during the COVID-19 pandemic surge was examined in this observational study.

Optical fiber sensors can measure strain, temperature, pressure, and many other physical parameters along the fibers, but they are currently immune to electromagnetic noise -- interference from other external electric or magnetic interactions. It is a desirable trait, until the effect of the electromagnetic field on the fibers needs to be measured. An international research team has used what was previously considered a 'damaged' part of an optical fiber to develop such a magnetic field sensor.

The outcomes of a cancer center-wide virtual care program launched in response to the COVID-19 pandemic were examined in this study.
