Algorithm ensures that random numbers are truly random

(Phys.org)—Generating a sequence of random numbers may be more difficult than it sounds. Although the numbers may appear random, how do you know for sure that they don't actually follow some complex, underlying pattern? ...

Genetic algorithms can improve quantum simulations

(Phys.org)—Inspired by natural selection and the concept of "survival of the fittest," genetic algorithms are flexible optimization techniques that can find the best solution to a problem by repeatedly selecting for and ...

Hybrid nanogenerator harvests hard-to-reach ocean energy

(Phys.org)—Energy from the ocean, or "blue energy," is arguably the most underexploited power source, according to researchers in a new study. Although the oceans contain enough energy to meet all of the world's energy ...

Scientists make battery electrodes from waste eggshells

(Phys.org)—Americans consume 76 billion eggs per year, and while some of the eggshell waste is used for fertilizer or dietary supplements, the majority of these eggshells are thrown away. In a new study, researchers at ...

Quantum thermal transistor can control heat currents

(Phys.org)—Researchers have designed a quantum thermal transistor that can control heat currents, in analogy to the way in which an electronic transistor controls electric current. The thermal transistor could be used in ...

Plasmonic pixels could be used to make non-fading paint

(Phys.org)—Researchers are developing a technology that could one day make paint and color packaging labels that never fade. The color is produced by a type of nanostructure called a "plasmonic pixel." These pixels are ...
