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

Consider, for your listening pleasure, the next frontier in sonic miracles: so-called "audible enclaves," where only you can hear a sound without disturbing anyone else in open space — no headphones required. As developed by a team of researchers at Penn State, whose findings are published as study in the journal Proceedings of the National Academy of Sciences, this technology can create pockets of sound isolated from their surroundings that can be targeted at a specific location, potentially p

The bleeding edge: Imagine listening to music or a podcast without headphones while not disturbing others or having a private conversation in a crowded place with the assurance that only the intended listener can hear your voice. Scientists have developed a new technology called "audio enclaves" that could make this a reality by creating localized pockets of sound isolated from their surroundings. Directing sound to a specific location is difficult because of how sound waves behave. As vibratio

What if you could listen to music or a podcast without headphones or earbuds and without disturbing anyone around you? Or have a private conversation in public without other people hearing you? Our newly published research introduces a way to create audible enclaves – localized pockets of sound that are isolated from their surroundings. In other words, we’ve developed a technology that could create sound exactly where it needs to be. The ability to send sound that becomes audible only at a spe

In a nutshell: Researchers from Nanyang Technological University in Singapore have demonstrated the ability to manipulate water waves, allowing them to precisely control objects floating on the surface. If perfected, the technique could pave the way for using waves in new and exciting ways. The idea was inspired by earlier work involving light that was conducted by Shen Yijie. A co-lead on the new project, Yijie realized that light and water can both move as waves and wondered if what they had

7 min read Over the years, Cloudflare has gained fame for many things, including our technical blog, but also as a tech company securing the Internet using lava lamps , a story that began as a research/science project almost 10 years ago. In March 2025, we added another layer to its legacy: a "wall of entropy" made of 50 wave machines in constant motion at our Lisbon office, the company's European HQ. These wave machines are a new source of entropy, joining lava lamps in San Francisco, suspend

Imagine hopping onto a large floatie in a lake or pool, and then trying to move. We’ve all been there—without paddling limbs, wind-catching sails, or a propelling engine, you’re stuck. But what if we could make the water itself move you? An international team of researchers has developed a technique to manipulate water and move floating objects with a level of precision that seems right out of a sci-fi movie. Beyond its inherent cool factor, this research could have practical applications, rang

Seismic waves suggest the planet's solid inner core is being pulled out of shape – and it has undergone these changes over just a few decades An illustration showing Earth’s inner structure Rostislav Zatonskiy/Alamy Earth’s solid inner core appears to have changed shape in the past 20 years or so, according to seismic wave measurements – but the behaviour of these waves could also be explained by other shifts at the centre of the planet. Since the 1990s, models and seismic measurements have i
