Breathing problems in teens: COVID-19 or lung injury due to vaping?
In a case series of three teen patients, UC Davis Health pediatricians present common manifestations of COVID-19 and lung injury due to vaping (EVALI).

Surprises in 'active' aging
Aging is a process that affects not only living beings. Many materials, like plastics and glasses, also age -- ie they change slowly as their particles try to pack better. Biological materials, such as living tissue, show similar behaviour to glasses except that the particles are actual cells with their own propulsion. Researchers at Göttingen University used computer simulations to explore the aging behaviour of these ''living'' glassy systems. Research was published in Physical Review Letters. (2020-11-18)

The problem with microwaving tea
Through convection, as the liquid toward the bottom of a container warms up, it becomes less dense and moves to the top, allowing a cooler section of the liquid to contact the heating source. This ultimately results in a uniform temperature. Inside a microwave, however, the electric field acting as the heating source exists everywhere and the convection process does not occur. Researchers studied this nonuniform heating behavior and present a solution in AIP Advances. (2020-08-04)
