Phys.org July 27, 2018 An international team of researchers (Israel, Albania) generated skyrmions using the electrical field of electromagnetic waves. They demonstrated that in contrast to “regular” light waves, whose electrical fields usually point along a specific direction an electric field can take on a “skyrmion” shape and simultaneously face in all directions and they are robust against various defects in the material hosting the electromagnetic waves. The discovery could enable future replication of this effect in a wide range of systems and materials, including liquids, nanoparticle systems and even cold atomic gasses. It might also lay the ground for […]

Researchers develop first-of-its-kind optic isolator
Phys.org July 13, 2018 Photonic isolator efficiency is necessary for applications that include quantum optics communication devices and building high-powered lasers. Researchers in Israel have constructed a spherical glass isolator. Light traveling in opposite directions is delivered to the sphere rotating at high speed. Counter-circulating light have different colors. In the future, the researchers may be able to generate such lasers that are based on vibrations where the restoring force is Casimir or Van der Waals. Using their self-aligned nano separation method might also allow MEMS… read more.
Here’s How Spies Can Use Your Phone to Find You And Eavesdrop With Ease
Science Alert June 01, 2018 The SS7 (Signaling System 7) created in the 1970s as a way for telecommunications carriers to exchange information as they routed calls, has little security, allowing intelligence agencies and some criminal gangs to spy on unwitting targets – based on nothing more than their cellphone numbers. As the number of companies with access to SS7 grew to many thousands, the lack of built-in security became a growing problem. It was easy for anyone with access to the network to pretend to be a carrier making legitimate requests for information about customers. According to an Israeli […]
