Bacteria build communities using chemical signals comparable to radio waves
The idea of bacteria coming together to form a socially organized community capable of cooperation, competition, and sophisticated communication may at first glance sound like science fiction — or just plain crude. But biofilm communities have important implications for human health, ranging from disease to aiding digestion. And they play a role in a range […]
Launch of television and radio in liberated Zangilan [PHOTO]
October 20, 2021 11:46 am (UTC + 04:00 am) 1,189 By Ayya Lmahamad Restoration work on infrastructure, including radio and television stations, continues in the liberated lands of Azerbaijan. In this context, television and radio broadcasts were launched in the city and more than 10 villages in the Zangilan region. Eight TV channels and two […]
Ultra-cold radio waves could enable dark matter detection and quantum computing
The radio waves have been cooled to close to their quantum ground state, a process that suppresses noise from radio detection, allowing even the weakest signals to stand out. This achievement could advance many areas of research where small fluctuations in temperature hamper progress, including the detection of dark matter, a step necessary to explain […]
Discovery and use of radio waves
By Robert M. Hazen, Ph.D., George Mason University There are a bunch of common divisions in this electromagnetic spectrum. They are radio waves; microwave; infrared or thermal radiation; then visible light; then ultraviolet; radiography; and gamma rays. This list is in order of increasing energy, also decreasing wavelengths. But one of the most important types […]
People only eat sandwiches: Subway transmits radio waves to Kurupt FM
Subway brought in fictional radio station Kurupt FM to take over their in-store broadcast network to celebrate the return of indoor dining. Kurupt FM is the radio station operated by Chabuddy G (played by Asim Chaudhry) featured in the former BBC comedy series People do nothing. Chabuddy G is joined in the takeover by MC […]
Quantum receiver capable of detecting the full spectrum of radio waves
A quantum sensor has been developed that can analyze the full spectrum of radio frequencies, which could open up new options for military communication. US Army researchers built the quantum sensor, which can sample from zero frequency up to 20 GHz, detecting AM and FM radio, Bluetooth, Wi-Fi and other communication signals along the way. […]
The space bubble created by radio communication signals protects against radiation
We’ve already managed to mess up Earth with everything from overfishing landfills to nuclear fallout, so it shouldn’t come as a shock that human activity is finally manifesting itself in space. The unexpected of our influence beyond the atmosphere is that it is (for once) positive. Something weird had pushed further and further away the […]
What are radio waves? | Live Science
Radio waves are a type of electromagnetic radiation best known for its use in communication technologies, such as television, cell phones, and radios. These devices receive radio waves and convert them into mechanical vibrations in the speaker to create sound waves. The radio frequency spectrum is a relatively small part of the electromagnetic (EM) spectrum. […]
The short and long radio waves | Local news
In a burst of light in 1864, James Maxwell theorized that electromagnetic waves – radio and light – could travel through free space without the mythical “ether” or “quintessence.” A few years later, Heinrich Rudolf Hertz – the unit of cycles per second bears his name – was able to prove that electromagnetic waves could […]
