Scientific vocabulary

I slightly lack vocabulary in the science sector (chemistry/biology/etc), and here I found an excellent site, which offers two podcasts, both providing transcripts, about chemistry and biology. Enjoy!

Have you tried the BBC’s science podcasts?

or are they not specialised enough for your needs?

Try Of all British this is the best in my opinion. It is made by a team from Cambridge. There are transcripts, many different voices, an archive for 10 years, several podcasts, all you can dream about.
