And the Hello and with him Chris Smith. This week how thanks to mobile gadgets and phones, we're hemorrhaging personal

information without even realizing it.

We'll hear how snoopers can eavesdrop on your mobile signals while you're out in public to track

down your home address. and what did a computer

scientist discover on a bunch of second-hand mobile phones picked up off eBay?

We'll talk to him to find out.

Plus the stories making the headlines from the world of science and technology

including figuring out just how much dark matter is in the Milky Way and a breath

test that could diagnose Parkinson's disease. The Naked Scientists Podcast is powered by UKfast.co.uk.

First up for people with type 1 diabetes whose pancreas doesn't make enough

of the glucose regulating hormone insulin life is dominated by testing

their blood sugar levels and injecting insulin.

But what if this injected insulin could be made smarter, circulating in the body until the exact time it's needed,

only springing interaction after a meal?

It sounds too good to be true, but now MIT scientist

Matthew Weber has made that happen, at least in mice. The idea was to try to make

insulin a little bit more autonomous if the insulin molecule itself could remain in the body,

but not be functional unless it was needed. So if blood glucose levels go up as a result of a meal,

then the insulin could turn on and become active versus the patient having to kind of know

when their blood glucose level was high and inject themselves.

Describe to me a bit more about this particular insulin, what does it look like and how

does it work?
