Hello and welcome to another working from home episode of No Such Thing as a Fish, a weekly

podcast coming to you from four undisclosed locations in the UK.

My name is Dan Schreiber, I am sitting here with James Harkin, Andrew Hunter Murray,

and I'm Anna Tijinsky and once again we have gathered around the microphones with our

four favorite facts from the last seven days and in no particular order, here we go.

Starting with you, Andy.

My fact is that spies can tell what people are saying by looking at the lights in the room

they're in.

So this is a new spying technique which has been discovered or I don't know what you do

with spying techniques but it's been found out by researchers from the Ben Gurion University

of the Negev and the Vizeman Institute of Science.

And what they found is that there are lots of different ways of eavesdropping on people

and this one is called lamp phone and what it means is if we're all talking in our

rooms, if there's a light bulb and has to be a hanging light bulb so you know a classic

bulb, your conversation will make tiny tiny vibrations on the surface and that will slightly

affect the light inside the bulb and you can get very cheap equipment like cost a couple

of hundred dollars and you just observe the light bulb from outside the room and you

can pick up what people are talking about.

You can decode speeches.

Can you do speeches?

Yeah so you can, it's not like Morris, it's not translating into Morris, you can pick

up the actual sound.
