Medical Xpress / Limited supply may scupper proposals to use antimalarials to ward off Covid-19

Limited global supplies may scupper proposals to use the antimalarial drugs, chloroquine and hydroxychloroquine, to lessen the symptoms of Covid-19 infection or ward it off altogether, say Italian doctors in a letter published ...

Phys.org / A new way to fine-tune exotic materials: Thin, stretch and clamp

One way to change the properties of a material is to stretch it just a wee bit, so its atoms are farther apart but the bonds between them don't break. This extra distance affects the behavior of electrons, which determine ...
