Scientists at Work


We have produced a Style Guide to help editors follow a standard format when editing a listing. If you are unsure how best to edit this programme please take a moment to read it.
Detecting the Invisible
How some plant diseases are investigated
This talk explains the investigations constantly being made by scientists into plant diseases given by mysterious things called viruses (not necessarily living organisms), so small that no pore of a filter can hold them back, and the lens of no microscope has yet been made that can magnify them enough to show them to the naked eye.
Dr. Kenneth Smith , who works at the Potato Virus Research Station, School of Agriculture, Cambridge, will describe how certain viruses are spread about by the sap of infected plants, others by carriers such as green-fly, others through the sludge in the bottom of tanks, others by contact with the human hand.
What a virus is, is not yet known.
It is being combated-for instance, by the English grower who buys his potato seed in Scotland where the virus is scarcer. The chemist, the physicist, the botanist, and the entomologist are all co-operating in the study of viruses and virus diseases in the interests of us all.

About this project

This site contains the BBC listings information which the BBC printed in Radio Times between 1923 and 2009. You can search the site for BBC programmes, people, dates and Radio Times editions.

We hope it helps you find information about that long forgotten BBC programme, research a particular person or browse your own involvement with the BBC.

Through the listings, you will also be able to use the Genome search function to find thousands of radio and TV programmes that are already available to view or listen to on the BBC website.

There are more than 5 million programme listings in Genome. This is a historical record of the planned output and the BBC services of any given time. It should be viewed in this context and with the understanding that it reflects the attitudes and standards of its time - not those of today.
