Radio signal broadcasts have their usefulness, but they eventually end (except, perhaps, for SETI). Every so often, we mark the public end of a once-essential wavelength, such as 3G cellular, analog television, or the Canadian time check. One of the most weirdly useful signals will soon end in the United Kingdom, with notable consequences if its transition is not properly handled. Beginning in the early 1980s, UK homes could have electrical meters installed with a radio teleswitch attached. The

The lighter creates a tiny spark that jumps from one wire to the other in the front pair. This spark creates electromagnetic waves, with the two wires serving as transmission antennas to amplify the waves. The two wires in back are the receiving antennas, and they will produce an electric current just like with Hertz’s loop of wire. Instead of creating a spark on the receiver, on my device the light bulb will turn on. The neon bulb is really nice since it's high-voltage but low-current, which is

Forward-looking: As rechargeable lithium-ion (Li-ion) batteries power everything from smartphones to electric vehicles, their limitations are becoming increasingly evident. Frequent recharging and environmental concerns related to lithium mining and battery disposal have prompted researchers to seek alternatives. A team led by Su-Il In, a professor at South Korea's Daegu Gyeongbuk Institute of Science and Technology, is developing an innovative solution: radiocarbon-powered nuclear batteries th

Remote detection The ability to locate radioactive material at distances greater than the range of emitted particles could play an important role in nuclear disaster response and nuclear security. (Courtesy: Shutterstock/fewerton) Researchers have demonstrated that they can remotely detect radioactive material from 10 m away using short-pulse CO 2 lasers – a distance over ten times farther than achieved via previous methods. Conventional radiation detectors, such as Geiger counters, detect par

After introducing for Android in September, YouTube Music’s AI-powered “Ask Music” radio generator is now available on the iPhone and iPad. Once rolled out, you’ll see an “Ask for music” shelf in the Home tab. It’s pretty close to the top of the main feed. There’s a carousel of 10 suggested prompts, with a tap automatically making a custom radio station. There’s also the “Ask any way you like” field with a voice input shortcut to enter your own prompt that “describes a mood, activity, or liste

When these stars dance, they make their own music. Astronomers have tracked down the source of a mysterious radio signal from deep space repeating every two hours. Intriguingly, it's a pair of stars in such a tight orbit that their magnetic fields regularly bump into each other — and it's this bodily percussion that appears to be blasting out the radio emissions we're picking up on Earth, roughly 1,600 light years away. The findings on the binary system, published in a new study in the journal

Andy Walker / Android Authority I love listening to music while driving. Finding tracks that suit the mood of any given road trip sets the overarching tone for the journey. While my partner and I usually curate driving playlists for this purpose, sometimes I want to listen to the radio when I’m alone. I can do just that with my car’s built-in receiver, but what if I want to hear something beyond my country’s borders? Perhaps stations from the US? Well, I recently stumbled across Non Stop Radio,

Here is part seven (the final part) of my non-fiction work about the National Radio Astronomy Observatory (NRAO) in Green Bank, West Virginia. You can also read parts one, two, three, four, five and six. The NRAO fleet The cars used on the NRAO campus are different from what you might expect. You’ll see photos of them below, and in case you’re wondering why they look so old, let me explain. Gasoline-powered cars generate more RFI than diesel-powered cars because they have spark plugs.

The vast realm probed by radio astronomers is one invisible to the naked eye, and even most kinds of telescopes. Now, thanks to the latest advances in radio observatories, scientists are uncovering an entire "low surface brightness universe" teeming with circular curiosities, according to a team of researchers from Australia — including an entirely new class of cosmic object. "It's comprised of radio sources so faint they have never been seen before, each with their own unique physical propert

[This post is part of “A Bicycle for the Mind.” The complete series can be found here.] The Early Electronics Hobby A certain pattern of technological development recurred many times in the decades around the turn of the twentieth century: a scattered hobby community, tinkering with a new idea, develops it to the point where those hobbyists can sell it as a product. This sets off a frenzy of small entrepreneurial firms, competing to sell to other hobbyists and early adopters. Finally, a handfu

Attention audiophiles: the archive of the BBC Radiophonic Workshop is being made available to the public for the first name. This department was founded in the 1950s as a laboratory that could invent original music and sound effects for BBC radio, and later television, programming. Over the years, its roster of innovative musicians and composers created audio for iconic BBC productions of the 1950s and 1960s such as Doctor Who, Hitchhiker's Guide to the Galaxy, the Goon Show and Blake's 7.
