A huge radio telescope array spread across the Australian Outback is helping identify the mysterious fast radio bursts. Astronomers have now announced the discovery of 20 new FRBs in a bit over a year, including the brightest and closest events yet seen.

As crucial as antennas are, the rigid metals they’re made of can limit what devices they can be built into. To help with that, researchers at Drexel University have developed a new kind of antenna that can be sprayed onto just about any surface.

Back in 2010, Sonitus Technologies introduced a novel in-mouth hearing aid called the SoundBite. Now the US Department of Defense has awarded the company a contract to develop a wireless two-way comms system that clips to a user's back teeth.

An international team of astronomers has detected the most distant radio galaxy ever observed. By measuring the redshift of its light, the researchers determined that the object is about 12 billion light-years away, which dates it back to when the universe itself was just a kid.

A brown dwarf was recently downgraded to planet status (albeit a huge one), and now astronomers have discovered that it generates an enormous magnetic field, which could provide a new tool in the search for exoplanets.

The MeerKAT radio telescope array is finally up and running in South Africa. To show off what the facility can do, astronomers have pointed all 64 antennas towards the center of the Milky Way galaxy, and snapped one of the clearest shots ever taken of the mysterious region.

Fast radio bursts (FRBs) are strange, extremely bright and mysterious signals from space. Now, astronomers at Australia’s Parkes Observatory have recorded three new signals in relatively quick succession – one of which is the brightest FRB ever detected.

Drones are increasingly crowding the airspace, so it’s only natural that the counter-drone market is growing too. The wide arsenal from DroneShield just got a little wider with the DroneGun Tactical, a new handheld jamming weapon that disrupts more frequencies from a smaller, more portable package.

Last year astronomers around the world witnessed the merger of two neutron stars as gravitational waves, light, radio and gamma rays, but the aftermath of the mashup hasn’t played out quite as expected. Rather than fade over time, the afterglow has continued to brighten.

An international team of astronomers has found that a strange repeating fast radio burst is even odder than previously thought. The radio waves from FRB 121102 are being “twisted” to an extreme degree, indicating that highly-magnetized plasma could be interfering.
