Microscopy system enabling broader biomedical applications

Optical-resolution photoacoustic microscopy (OR-PAM) is a powerful imaging tool with a superb ability to image rich optical absorption contrast in biological tissue. Most OR-PAM systems today rely on mechanical scanning to form an image, which restrains their imaging speed. To overcome the restraint, multifocal OR-PA computed tomography (MFOR-PACT) had been developed by utilizing a microlens array with multiple optical foci and an ultrasonic transducer array to detect PA signals in parallel.

Previous vaccines and masks may hold down Covid-19, some researchers say

As US leaders work to control the spread of coronavirus, researchers across the globe are working to answer the mysteries that remain around infections.

Lawmakers urge the FDA to temporarily clear e-cigarettes from market amid Covid pandemic. Here's why

In a letter to the US Food and Drug Administration, lawmakers are urging the agency to temporarily clear the market of all e-cigarettes for the duration of the coronavirus crisis.

A Japanese robotics startup has invented a smart mask that translates into eight languages

When the Covid-19 pandemic made face masks an everyday essential, Japanese startup Donut Robotics spotted an opportunity. They created a smart mask — a high-tech upgrade to standard face coverings, designed to make communication and social distancing easier.

Researchers created a test to determine which masks are the least effective

Schools are reopening, amusement parks are welcoming back visitors, and outdoor dining is the new way to eat out. But despite the signs that life is returning back to normal, the coronavirus pandemic has gone nowhere.
