Bacteria communicate using chemical signals comparable to radio waves

Scientists have shown that the bacterium Pseudomonas aeruginosa communicates using chemical signals analogous to radio signals to help cells group together and form communities. Credit: Janice Haney Carr/CDC The UCLA-led study could have implications for medical research and sustainability. The idea of ​​bacteria coming together to form a socially organized community capable of cooperation, competition, […]

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 […]

Mysterious radio waves from the heart of the Milky Way confuse astronomers

Astronomers have detected mysterious radio waves originating from the center of the Milky Way, but so far have no idea what causes them, according to a new study published in the Astrophysical Journal on Tuesday. A team of scientists from around the world discovered the object using the CSIRO radio telescope in Western Australia. Ziteng […]

Space: mysterious radio waves arrive from the center of the galaxy

Through Lea Crane Illustration of radio waves coming from the galactic center Sebastien zentilomo Strange radio signals are coming from the center of the galaxy and we don’t know what is emitting them. They seemingly turn on and off at random, and their source must be unlike anything we’ve seen before. The source of this […]

Variable signal aligned at the heart of the Milky Way galaxy appeals to scientists – sciencedaily

Astronomers have discovered unusual signals coming from the direction of the center of the Milky Way. The radio waves do not correspond to any currently understood model of a variable radio source and could suggest a new class of stellar objects. “The strangest property of this new signal is that it has a very high […]

Radio waves and tools for TPMS

How do you diagnose what you can’t see? TPMS and keyless entry can be difficult to understand because these systems rely on the transmission, reception and decoding of radio waves, but these signals are invisible. You can see the wires connecting modules and components and observe them with a counter or oscilloscope. But, seeing the […]

Radio waves and TPMS tools

TPMS and keyless entry can be difficult to understand because these systems rely on the transmission, reception and decoding of radio waves, but these signals are invisible. You can see the wires connecting modules and components and observe them with a meter or oscilloscope, but seeing the radio signals requires smart tools. Click here to […]

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 […]

Famous FRB radio waves surprisingly long and late | Space

In this illustration, a burst of radio emission from a repeating fast radio burst arrives at the LOFAR telescope. The longest part of the signal (red) is much longer than ever before from a fast radio burst. Also, the longer wavelength emission arrives about 3 days later than the shorter wavelength (higher frequency, shown in […]

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. […]

How to explore the hidden world of radio waves all around you

One day this fall, in an old factory in Brooklyn’s Bushwick neighborhood, a row of ’90s pagers chirped and buzzed. Next to their dimly lit screens was a receipt printer – like the one you might find in a cash register – spitting out long spools of paper. As my eyes scanned the prints, I […]
