(Phys.org) —Sometimes mathematical theories have implications that extend far beyond their original purpose. This situation holds true for the four-color theorem, which was originally used by cartographers hundreds of years ...
The DNA double helix is composed of two DNA molecules whose sequences are complementary to each other. The stability of the duplex can be fine-tuned in the lab by controlling the amount and location of imperfect complementary ...

Materials scientists are often bioinspired, and in a new study, bird-inspired by structural colors exhibited by avian species to form non-iridescent nanoparticle assemblies. Such nanoparticle mixtures varying in particle ...
Imagine stretching a piece of film to reveal a hidden message. Or checking an arm band's color to gauge muscle mass. Or sporting a swimsuit that changes hue as you do laps. Such chameleon-like, color-shifting materials could ...

In a new report now published on Science Advances, Paulo H. Michels-Brito, and a team of researchers in physics, inorganic chemistry, and physical chemistry in Germany and Norway, showed how bright non-iridescence structural ...
Colloidal crystals and glasses are tunable, iridescent, nonfading and nontoxic materials that can be used to develop structural colors. In a new report now published in Science Advances, Jong Bin Kim, and a team of researchers ...
A novel three-dimensional (3-D) touchless interactive display can change color based on the distance of the user's finger from the screen by detecting subtle shifts in ambient relative humidity, according to a new study. ...
Brilliantly colored chameleons, butterflies, opals—and now some 3-D-printed materials—reflect color by using nanoscale structures called photonic crystals.

Inspired by the way iridescent bird feathers play with light, scientists have created thin films of material in a wide range of pure colors—from red to green—with hues determined by physical structure rather than pigments.
