Hello, this week, Humanity 2.0, can we use genetics, drugs and technology

to become superhuman.

Plus in the news, do men and women really think differently?

Why what we call a kilogram is changing and researchers uncover an animal that can talk about the past.

I'm Georgia Mills. I'm Chris Smith and this is

the Naked Scientist. The Naked Scientist podcast is powered by UKfast.co.uk. UK. First up with rising global temperatures, heat waves are becoming more frequent and more intense.

But what impact is this having on the plants and insects all around us?

As the temperature of our planet goes up,

biodiversity tends to fall, but researchers have been stumped as to why. Now a team at the

University of East Anglia have found that just like tight pants are bad for

boys, heat waves can compromise sperm counts in insects. Isie Clark heard how from Matt Gage.

So although there's been a lot of research looking at

warm-blooded species and how heat can impact on male fertility and sperm function,

there's been very little work looking at

cold-blooded species like insects for example, which we thought was quite a knowledge

gap because most of biodiversity on our planet is cold-blooded.
