This week, how taxing our food could improve our health and the climate.

You could save about 1 billion tonnes of carbon dioxide equivalent, so that is more than global aviation emit.

And paralyzed monkeys walk again with the aid of a wireless brain spine link.

We turned it on, and on the very first day and we tested it,

the animal was showing a stepping movement of this paralyzed leg.

And I remember a lot of screaming in this room

because it seemed like incredible to observe this recovery.

Plus what neuroscience can learn from big physics.

This is the nature podcast for November the 10th, 2016. I'm Adam Levy.

And I'm Kerry Smith.

Neuroscientists around the world are making their way to San Diego for the biggest

neuro meeting of the year, the Society for Neuroscience Conference.

In honour of the tens of thousands of attendees, we've got a couple of brain-themed tip bits for you this week.

Take it away, Kerry.

When neuroscientist Gregor Cortine was in his late 20s, he was working as a postdoc in Los Angeles,

figuring out how the brain and spinal cord control walking. And in studying how

that works and what happens when it goes wrong, he started to meet patients with spinal cord

injuries who were wheelchair-bound. It was a very strong moment for me because at the time I was

27 years old when I was a postdoc in Los Angeles and I was doing all this experiment with young men of my age

because now you have a lot of, of course, sport accident, car accidents.

It's almost like you can relate to them because of the age that is very similar

and that really created this bond that really encouraged me to follow this line of research.
