In a surprising discovery, Princeton physicists have observed an unexpected quantum behavior in an insulator made from a material called tungsten ditelluride. This phenomenon, known as quantum ...

Mineral wool batts for 2×6 walls have an R-value of 23, compared with R-19 for fiberglass batts. A 2×4 stud cavity filled with blown-in cellulose has an R-value of about 13. Spray foam insulates ...

Complex connections Schematic of the 4D metamaterial (left), and photographs of its experimental realization in a circuit (right). (Courtesy: Wang et al.) Materials known as topological insulators ...

Drafty, energy-inefficient windows aren't just a problem during the winter. They are just as big an issue in the summer, when cool air can escape through gaps and the sun's heat pours in through the ...

Chinese researchers have developed a new carbon nanotube insulator that can withstand high temperatures up to 2,600°C, ...

Science can be difficult to explain to the public. In fact, any subfield of science can be difficult to explain to another scientist who studies in a different area. Explaining a theoretical science ...
