Traveling-wave parametric amplifiers (TWPAs) are electronic devices that boost weak microwave signals (i.e., electromagnetic waves with frequencies typically ranging between 1 and 100 GHz). Recently, many engineers have been ...
Sometimes you get a small electric shock from touching your car door handle on a dry summer's day.
A team from the Faculty of Physics and the Center for Quantum Optical Technologies at the Center of New Technologies, University of Warsaw has developed a new method for measuring elusive terahertz signals using a "quantum ...
Highspeed Internet, autonomous driving, the Internet of Things: data streams are proliferating at enormous speed. But classic radio technology is reaching its limits: the higher the data rate, the faster the signals need ...
A new type of sensor that levitates dozens of glass microparticles could revolutionize the accuracy and efficiency of sensing, laying the foundation for better autonomous vehicles, navigation and even the detection of dark ...
If you dissolve sugar in hot water and then cool it down, you'll see pure sugar crystals form while impurities stay in the liquid. You can even watch the beautiful sugar crystals slowly grow in the water.
The research group FQM-215—Affordable and Sustainable Sample Preparation at the University of Córdoba has developed a method that is not only faster and easier to perform but also more environmentally sustainable. It can ...
Scientists working with the James Webb Space Telescope discovered three unusual astronomical objects in early 2025, which may be examples of dark stars. The concept of dark stars has existed for some time and could alter ...
In the early 1930s, Swiss astronomer Fritz Zwicky observed galaxies in space moving faster than their mass should allow, prompting him to infer the presence of some invisible scaffolding—dark matter—holding the galaxies together. ...
In 1882, the French Naturalist Camille Viguier was among the first to propose the existence of a magnetic sense. His speculation proved correct. Many animals—from bats, to migratory birds and sea turtles use the Earth's magnetic ...
