Several countries are building futuristic communication systems using higher frequency electromagnetic waves to transfer more data at faster rates, but they have lacked network components to handle these higher bandwidths. Researcher J. Gary Eden proved his new device can rapidly switch functionality to perform the varied tasks needed to support a network with carrier frequencies of over 100 gigahertz. The miniscule-scale architecture concealed within the sugar cube blocks is described in Applied Physics Reviews.

Organisations aren't moving quickly enough on cyber security threats linked to the drive toward using personal mobile devices in the workplace, warns a QUT privacy researcher.

On its first two flybys of the sun, the Princeton-led instrument IS?IS detected a surprising variety of activities by solar energetic particles -- the zippy electrons, protons and other ions that fly out in advance of the solar wind -- that can disrupt space travel and communications on Earth. Researchers are investigating how these particle events form, findings that will shed light on broader questions about the sun, space weather and cosmic rays.

The University of Cincinnati is developing robotic networks that can work independently but collaboratively on a common task. The goal? To make smart satellites that can repair other satellites in space.

An Army-funded project may boost 5G and mm-Wave technologies, improving military communications and sensing equipment.

Sensing a hug from your friend through a video call with him/her may become a reality soon. A joint-research team consisted of scientists and engineers from City University of Hong Kong (CityU) and Northwestern University in the United States has developed a skin-integrated virtual reality (VR) system, which can be controlled and powered wirelessly. The innovation has great application potential in communications, prosthetic control and rehabilitation, as well as gaming and entertainment.

Switching light beams quickly is important in many technological applications. Researchers at ETH have now developed an 'electro-opto-mechanical' switch for light beams that is considerably smaller and faster than current models. This is relevant for applications such as self-driving cars and optical quantum technologies.
