A blog about science and movies.
If you’re tired of your neighbor stealing your wi-fi, French researchers have come up with a solution – a metallic wallpaper that blocks out and filters electromagnetic waves. The paper can contain wireless signals, preventing someone from accessing them outside a home or office, while also amplifying the signal inside.
The scientists who created the metapaper say it also makes your home safer, by cutting down on the amount of electromagnetic radiation a person is exposed to. Take that, aliens!
