An anonymous reader quotes a report from ZDNet: Google patched last month an Android bug that can let hackers spread malware to a nearby phone via a little-known Android OS feature called NFC beaming. NFC beaming works via an internal Android OS service known as Android Beam. This service allows an Android device to send data such as images, files, videos,…

NHS Pagers Are Leaking Medical Data
An anonymous reader quotes a report from TechCrunch: An amateur radio rig exposed to the internet and discovered by a security researcher was collecting real-time medical data and health information broadcast by hospitals and ambulances across U.K. towns and cities. The rig, operated out of a house in North London, was picking up radio waves from over the air and translating…
The Crab Nebula was an exploding star
The Crab Nebula, about 6,500 light-years from Earth, is the scattered fragments of a supernova, or exploding star, observed by earthly skywatchers in the year 1054. Source: https://earthsky.org/clusters-nebulae-galaxies/crab-nebula-was-an-exploding-star…
Galaxy found to float in a tranquil sea of halo gas
Using one cosmic mystery to probe another, astronomers have analyzed the signal from a fast radio burst, an enigmatic blast of cosmic radio waves lasting less than a millisecond, to characterize the diffuse gas in the halo of a massive galaxy.

The 2nd-fastest pulsar, now with gamma rays
Pulsars are the compact remnants of supernovae. They have strong magnetic fields and rotate rapidly. This one is spinning 707 times a second! Astronomers just discovered this pulsar is emitting high-energy gamma rays. Source: https://earthsky.org/space/2nd-fastest-pulsar-j0952-0607-gamma-rays…
Radiowaves from electric devices may affect the body clock of insects
Radiofrequency fields appear to have an effect on cockroaches. If confirmed, the finding could mean that radio waves affect us too – but scientists are sceptical Source: https://www.newscientist.com/article/2216690-radiowaves-from-electric-devices-may-affect-the-body-clock-of-insects/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
