Tech Xplore / Laser-assisted 3D printing can fabricate free-standing thermoset-based electronics in seconds

Thermosets, such as epoxy and silicon rubbers, are a class of polymer (i.e., plastic) materials that harden permanently when they undergo a specific chemical reaction, known as "crosslinking." These materials are highly durable, ...

Phys.org / How supplemental feeding boosts reproductive conditions of urban squirrels

Urbanization is rapidly growing worldwide, often bringing negative effects on wildlife through loss of habitat and disturbances such as light pollution and noise. Yet some species manage to adapt to cities, either due to ...
