Mysterious repeating radio signal traced to 'vampire' star that's slowly eating its companion

Mysterious repeating radio signal traced to 'vampire' star that's slowly eating its companion Radio astronomers have decoded a peculiar repeating radio signal from deep space, tracing it to a vampiric binary star system. A pair of spiralling stars could be a blueprint for decoding mysterious bursts of radio energy coming from space, according to new research. Long-period transients have puzzled radio astronomers since they were first detected in 2022.

Scientists locate source of mysterious radio signals after 20 year search: A vampire star and its victim

Scientists locate source of mysterious radio signals after 20 year search: A vampire star and its victim The vampire star is ripping material off that friend. The clashing magnetic fields of a white dwarf star and its neighboring red dwarf star are the source of signals from space that have remained a puzzle for over 20 years, radio astronomers in Australia have found. The signals, or long-period radio transients, are a class of celestial radio emissions discovered in 2005.

Sydney community radio to avoid axe under reduced capacity model

Sydney's 2SER community radio to avoid closure under reduced model Wed 3 Jun 2026 at 4:09pm In short: Sydney community radio station 2SER will continue to broadcast beyond July under a reduced funding and staffing model. The University of Technology Sydney will become the sole funder of the station. Former ABC presenter and current 2SER volunteer Robbie Buck says the station needs to secure its future with other financial partners.

Proteins can be selectively controlled with radio waves

Proteins can be selectively controlled with radio waves Lisa Lock Scientific Editor Robert Egan Associate Editor In a significant advance in biological quantum sensing, a research team led by the Technical University of Munich (TUM) has discovered and tested a new mechanism of action in which proteins can be controlled with radio waves. In doing so, they influence a sensitive quantum state known as spin and make it visible via light. In the future, such findings could help detect and even...

I replaced Spotify with a homemade FM radio station

In the interests of reducing my screen time and phone use, I ended up spending far too many hours glued to my laptop trying to build a custom FM radio station. As part of a wide-ranging quest to achieve a minimalist lifestyle, a few months ago I ditched Spotify et al in favour of good old-fashioned linear broadcasting, via a cheap FM radio sat on the kitchen counter. This has worked mostly fine, but as a transhemispherical immigrant I found myself missing UK shows and finding my niche...

In the 60s and 70s, Black students demanded a voice on radio. A new project ensures that history isn’t lost

The HBCU Radio Preservation Project celebrates stations that were an outgrowth of the civil rights movement, to help people understand their importanceAfter Shaw University’s WSHA radio station went on air in 1968, several other historically Black colleges and universities (HBCUs) followed the North Carolina school’s lead, launching a wave of their own.For decades, the students who worked on these channels used them to inform listeners about happenings on campus, while also playing musical...

Interstellar object 3I/ATLAS reveals no technosignatures in seven-hour radio scan

Scientists at the SETI Institute recently searched for technological signals from 3I/ATLAS, the third interstellar object observed in our solar system. Using the Allen Telescope Array (ATA) at the Hat Creek Radio Observatory in Northern California, the team scanned a wide range of radio frequencies for signs of extraterrestrial technology and found none, as expected based on other astronomical observations showing that the object exhibits natural comet-like composition and behavior. The...

Energy-Efficient Aggregation and Minimum-Degree Spanning Trees in Radio Networks

Announce Type: new Abstract: We study the aggregation problem in synchronous multi-hop radio networks with $O(\log n)$-bit messages and no collision detection. Each node initially holds a value, and the goal is to compute a global aggregate such as the sum of all values. Aggregation tasks arise naturally in wireless sensor networks, where nodes are often battery-powered and radio activity is the dominant source of energy consumption.
