Researchers are developing AI-powered radio systems that can flexibly share spectrum frequencies in real time rather than relying on fixed allocations. This dynamic sharing approach would let devices like phones, satellites, and radar systems use the same frequency bands without interfering with one another, easing pressure on an increasingly crowded resource.
Scientists reportedly produced a previously unknown crystalline form of water ice while subjecting samples to temperatures near 2,357 degrees Celsius, conditions far beyond those where ice normally exists. The extreme heat was paired with high pressure to force water molecules into a novel structural arrangement not seen in standard ice phases.
Researchers at Curtin University analyzed 76 million radio images over 29 days using a prototype SKA-Low station and detected 112,534 unauthorized emissions from 1,806 Starlink satellites within the exact frequency band needed to study cosmic dawn hydrogen signals. The leakage, published in Astronomy & Astrophysics, comes not from intentional Starlink transmissions but from unplanned electronic interference radiating through satellite hardware, including periodic 13-kHz tones near 137 MHz.
A new project compiles the GNU Radio DSP engine and its Qt GUI sinks to WebAssembly, letting users build and run software-defined radio flowgraphs directly in a browser tab without installing Python or GNU Radio. It supports the same .grc flowgraph files as the desktop app, includes sample flowgraphs and IQ recordings, and can connect to RTL-SDR, PlutoSDR or HackRF hardware through WebUSB.
Fast Company has released its Best Workplaces for Innovators 2026 rankings, naming 22 companies in the North America category as standouts judged for fostering innovation. The winners span a wide size range, from small operations like Not Impossible Labs to established brands such as Radio Flyer.
Journalist Shawn Reynaldo revealed in his newsletter First Floor that rising indie artist Betty Hammerschlag, praised by The Guardian and The Quietus and played on NTS Radio, is actually a persona created by 45-year-old German musician Tilman Hornig. Hornig used stolen photos and a Gen Z-style writing voice to build the fake identity, even messaging young female and queer artists while posing as her, including collaborator tibslc who believed she was working with a young woman.
Earth Garden is a web tool that lets users spin a 3D globe and hear real-world ambient sounds tied to specific locations, from ocean waves near Atlantic islands to crickets in Tanzania and rainfall in Manhattan. The audio clips are sourced from Freesound, and the site can auto-rotate the globe, blending in new recordings as it moves, with an option to layer ambient drone sounds over the top.
Ruchira Shree, a New Jersey high school sophomore active with IEEE's Princeton Central Jersey Section, interned with the Alliance for Indigenous Math Circles, a group that runs STEM camps for Native American students. During the camp, she helped participants prepare for and pass amateur ham radio licensing exams as part of broader math and technology instruction.
The magic eye tube, invented by Allen B. DuMont in 1932, was a vacuum tube used to visually indicate signal strength in radio receivers, helping users tune into stations accurately. RCA released the first commercial version, the 6E5, in 1935, and these tubes remained common in radios until around 1980, when transistors replaced vacuum tube technology.
Researchers at MIT, led by Saransh Sharma with senior authors Giovanni Traverso and Anantha Chandrakasan, developed an ingestible capsule that measures body temperature to within 0.01°C. The device runs on a coin-cell battery and uses backscattering to shift most power demands to an external antenna, resulting in what they call the smallest ingestible temperature sensor yet built.
