Scientists Propose a Smarter Way to Hunt for Alien Radio Signals

The search for extraterrestrial intelligence (SETI) has yet to detect alien technosignatures like radio waves, but the cosmos is vast, and there are plenty of places left to look. New research suggests refining our search parameters by using our own broadcasts into deep space as a helpful guide. Research published earlier this week in Astrophysical Journal Letters suggests we search for alien signals by studying how we beam strong, directed transmissions during two-way communication with our de

Petabit-class transmission over > 1000 km using standard 19-core optical fiber

An international research team led by the Photonic Network Laboratory at the National Institute of Information and Communications Technology (NICT, President: TOKUDA Hideyuki Ph.D.), and including Sumitomo Electric Industries, Ltd. (Sumitomo Electric, President: INOUE Osamu) have set a new world record in optical fiber communications, achieving data transmission at 1.02 petabits per second over a distance of 1,808 kilometers (roughly equivalent to the distance from Sapporo to Fukuoka, from Misso
