Physicists have improved the accuracy of a technique that uses variable stars to measure distances in the universe, providing a new figure for its expansion rate. When you purchase through links on ...

While efforts are made to improve tissue quality and control preanalytical variables, pathologists are often confronted with the challenge of molecular analysis of patient samples of unknown quality.

New research offers the most precise measurements yet of pulsating Cepheid stars, which may hold clues about the immense size and scale of our universe. Cepheids are a type of variable star that ...

Yardsticks are very useful around the house when you need a measurement. (I have also used them to fish out toys the cat knocked under a low piece of furniture.) They are standards by which we can ...

Many physical platforms, including photons, ions, atoms, solid state and superconducting devices, and nuclear magnetic resonance 1, are being explored with the view of constructing a quantum computer.

Industrial furnaces can be heated electrically or using gas. Metal tools and components can be annealed and tempered via heat treatment in these furnaces. The heat treatment processes in the furnaces ...
