Scientists have finally pinpointed the source of mysterious, slowly repeating bursts of radio waves from space: a red dwarf star likely orbiting a white dwarf. This discovery challenges existing theories about pulsars and opens up new avenues of research into stellar interactions and radio wave emission.
A comprehensive new study published in Environment International has found no evidence that radio waves emitted by smartphones and other wireless devices cause brain cancer, dispelling long-standing concerns. The research, a review of 63 previous studies, suggests that even extensive smartphone use does not increase the risk of brain tumors.
A large-scale review of studies has confirmed that there is no link between mobile phone use and brain cancer. The World Health Organization-commissioned study analyzed over 5,000 research papers and found no association between radio wave exposure from mobile phones and an increased risk of brain cancer, despite previous concerns.
Dark matter, a mysterious component of the universe that makes up about 85% of its total mass, has eluded detection despite decades of research. However, new theoretical research suggests that waves in an ocean of dark matter could generate detectable radio waves that would allow us to finally find this elusive component of the universe. The study, published in the preprint server arXiv, explores models of ultralight dark matter that interacts extremely rarely with normal matter. When this dark matter interacts with plasma waves in Earth’s ionosphere, it could produce a resonance that amplifies the interaction and produces radiation in the form of radio waves. Using a carefully tuned radio antenna, scientists may be able to detect these radio waves and finally study one of the most mysterious elements in the universe right on our cosmic doorstep.
