As more devices get piled onto computer chips to increase processing power capacity, heat generation becomes increasingly concentrated. This heat must be removed to keep chip performance high, but is currently achieved by ...

New research from the University of St Andrews has discovered how Incas used Andean balance scales and ancient string knot writing known as "khipus," in association with sacred, animate landscapes.

Food quality and safety are crucial. However, conventional food-monitoring methods, including ribotyping and polymerase chain reaction, tend to be destructive and lengthy. These shortcomings limit their potential for broad ...

Scientists have discovered living microbes producing methane in the fractured rocks deep inside Sweden's Siljan impact crater, offering insights into Earth's earliest life and the search for life beyond our planet.

Exceptional points (EPs) are non-Hermitian singularities where two or more eigenstates coalesce, resulting in the eigenspace collapsing in dimensionality. Over the past decade, researchers have uncovered a wealth of exotic ...

Imagine biting into a crisp, garden-fresh salad and savoring juicy strawberries for dessert. But instead of your backyard, you're gazing out at a stark lunar landscape, Earth hanging like a precious blue marble in the inky ...

Scientists have developed a new platform for the generation and detection of ultrashort UV-C laser pulses on femtosecond timescales. This breakthrough could unlock new opportunities for transforming optical wireless communication ...

During the annual salmon run last fall, University of Washington researchers pulled salmon DNA out of thin air and used it to estimate the number of fish that passed through the adjacent river. Aden Yincheong Ip, a UW research ...

Astronomers from the University of Hawaiʻi Institute for Astronomy (IfA) have uncovered the turbulent past of a distant red giant by listening to its celestial "song." Subtle variations in the star's brightness suggest that ...

Researchers from the University of Oxford have for the first time discovered an approach to electrically switch organic LEDs (OLEDs) to emit either left- or right-handed circularly polarized light without changing the light-emitting ...

The genetic code is the recipe for life, and provides the instructions for how to make proteins, generally using just 20 amino acids. But certain groups of microbes have an expanded genetic code, in which one or two additional ...

Inside the cell reside many tiny assembly factories and warehouses that gather together all of the proteins and RNAs—which carry out instructions from our DNA—that a living being needs.
