As if attacks on health workers weren’t upsetting enough, reports indicate broadband engineers are now also being abused - as conspiracy theorists link 5G technology with to COVID-19’s spread.
The electromagnetic spectrum we can access with current technologies is completely occupied. This means experts have to think of creative ways to meet our rocketing demands for data.

Free space optical communication will allow the same connectivity in space we already have on Earth. And this will provide benefits across a number of sectors.
“No Linky” posters in Montreuil, near Paris. The first one reads “Linky: You can say no.” The second reads “Linky spies on your private life.” Some residents fear data surveillance rather than looking at possible advantages of smart meters.

Is it necessary to control exposure to electromagnetic waves by limiting the number of relay antennas? Yes, but that’s not the only thing.
Studies show wifi, mobile phones and other sources of electromagnetic radiation don’t make us sick. So, why are some people convinced they’re electrosensitive?

Studies suggest electrosensitivity is a “communicated” disease, spread by people hearing about the alleged dangers, and sometimes worrying themselves sick.

Astronomers were looking forward to the first high-res X-ray spectra from space, and all they would tell us about the cosmos. But unknown disaster seems to have befallen the Japanese satellite.
