Grzanka disputed the study’s methods and significance noting that parents’ own beliefs and biases about gender almost certainly influence how they described their children’s gendered play, which could skew their reporting.

UT-ORNL: Small Nanoparticles Have Surprisingly Big Effects on Polymer Nanocomposites

Polymer nanocomposites mix particles billionths of a meter (nanometers, nm) in diameter with polymers, which are long molecular chains. Often used to make injection-molded products, they are common in automobiles, fire retardants, packaging materials, drug-delivery systems, medical devices, coatings, adhesives, sensors, membranes and consumer goods. When a team of scientists, including UT’s Alexei Sokolov, tried to verify
