Georgia Tech system promises camera-free in-home pet tracking

While many dog (or cat) owners would like to know what their pet does all day while left home alone, they don’t necessarily want a bunch of cameras placed inside their house. The PetTrack system offers a less intrusive alternative, as it keeps tabs on … Continue reading Georgia Tech system promises camera-free in-home pet tracking

Bizarre radio burst with “heartbeat” rhythm is longest detected by far

Astronomers have detected an extremely strange radio signal from a distant galaxy that pulses with a heartbeat-like rhythm. This signal lasted about 1,000 times longer than other fast radio bursts (FRBs), and had a clear periodic pattern to its pulses…. Continue reading Bizarre radio burst with “heartbeat” rhythm is longest detected by far

Bizarre radio signal repeating every 18 minutes discovered in Milky Way

Astronomers have discovered a bizarre radio signal coming from somewhere in our galaxy that can’t be explained by any known object. When it’s active the source gives off energetic radio bursts lasting up to a minute, every 20 minutes – which should be … Continue reading Bizarre radio signal repeating every 18 minutes discovered in Milky Way

Mysterious radio signals may be coming from undiscovered planets

Astronomers have discovered strange radio signals that could be coming from unseen planets. Models suggest that some of the signals could be produced through interactions between the magnetic fields of planets and their host stars, which could represen… Continue reading Mysterious radio signals may be coming from undiscovered planets

Scientists harvest Wi-Fi signals to power an LED

Scientists have been working for years to harvest the power of ambient radio waves to power small devices, and these days there is hardly a richer source of these signals than Wi-Fi networks. Researchers have demonstrated a new approach to harnessing t… Continue reading Scientists harvest Wi-Fi signals to power an LED

Astronomers detect new frequencies from mysterious fast radio bursts

The mystery of fast radio bursts (FRBs) from space may be a step closer to being solved. Astronomers studying a repeating signal from a nearby galaxy have detected radiation at the lowest frequency of any FRB found so far, providing new potential hints… Continue reading Astronomers detect new frequencies from mysterious fast radio bursts

AI monitoring system warns patients of improper inhaler usage

Even though at-home use of an inhaler or insulin pen can be extremely important, doctors have to pretty much just hope that patients are doing it right. A new system, however, could objectively assess patients’ technique within their homes, and let the… Continue reading AI monitoring system warns patients of improper inhaler usage

Cold gas cloud in our galaxy could be hiding universe’s missing matter

By studying the twinkling of stars, astronomers in Australia have discovered a huge cloud of cold gas in our galaxy, not far from Earth. This invisible mass could provide new hints about where to find the universe’s missing matter.Continue ReadingCateg… Continue reading Cold gas cloud in our galaxy could be hiding universe’s missing matter

Lunar orbiter to listen for radio signals from cosmic “Dark Ages”

The National Radio Astronomy Observatory (NRAO) has announced a new addition to NASA’s upcoming moon-shot Artemis program. From the silent skies on the far side of the Moon, the DAPPER spacecraft will listen out for radio signals from the “Dark Ages” o… Continue reading Lunar orbiter to listen for radio signals from cosmic “Dark Ages”

Wireless system uses radio signals to monitor sleep positions

In order to track how someone’s body position changes as they sleep, they typically either have to be rigged up with stick-on sensors, or filmed by a video camera. MIT’s new BodyCompass system, however, offers a third alternative that many people may p… Continue reading Wireless system uses radio signals to monitor sleep positions
