From glowing cats to wombats, fluorescent mammals are much more common than you’d think

After combing through museum collections, our team of researchers found a whopping 125 fluorescent mammal species – from polar bears and dolphins, to leopards, zebras and wombats.

We’re using lasers and toaster-sized satellites to beam information faster through space

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. Carole Salères

Linky: Do smart meters actually help reduce electricity consumption?

A recent study suggests that smart meters can help households reduce their electricity use by as much as 5%. Are France’s anti-Linky households listening?
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? from www.shutterstock.com

Apocalypse now: wifi and radiation sickness sweeping the world

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

Let there be light! Celebrating the theory of electromagnetism

It’s hard to imagine life without mobile phones, radio and television. Yet the discovery of the electromagnetic waves that underpin such technologies grew out of an abstract theory that’s 150 years old…

Explainer: how hostile is space?

Space may seem calm, but it is a more hostile environment than that on Earth. Invisible radiation is a big problem for space enthusiasts and scientific instruments. Substituting electronic devices to do…
