scientist 69: the science author – Michael Freemantle says WW1 was the chemists war (2014)
The First World War, that began in 1914, put chemists to work. Their chemicals could harm as well as heal ... but on balance the outcome was ... horrific.

As the author of two books about the First World War, Dr Michael Freemantle explains chemistry was the destructive force in the war but it also protected the troops, and healed the wounded.
Scroll down for the recording.
Additional notes by Roger Frost - with thanks to Dr Freemantle. 
Attitudes to chemical warfare back then:

At one point chemical weapons were considered by the British to be a MORE humane way to kill people. A speech recorded at the USA National Center for Biotechnology Information suggests that the use of chemical weapons may best be understood by listening to the scientists who had firsthand knowledge of their development.

Writing in the late 1960s, chemist James Conant, who directed US GAS production during World War One, said: To me, the development of new and more gases seemed no more immoral that the manufacture of explosives and guns. . . . I did not see in 1917 . . . why tearing a man’s guts out by high explosive shell is to be preferred to maiming him by chemicals attacking his lungs or skin. All war is immoral.

On the German side, Otto Hahn, a future Nobel prize winner in chemistry, was recruited by Fritz Haber to the German chemical weapons program. Otto Hahn went to the eastern front to see the capabilities of this new weapon. The experience left him profoundly shaken: "I was very ashamed and deeply agitated. First we attacked the Russian soldiers with our gas, and then, when we saw the poor chaps lying on the ground slowing dying, we restored their breathing with our rescue equipment. The total insanity of war became obvious to us. First one attempts to eliminate the unknown enemy in his trench, but when one comes face to face with him, one cannot bear it and sets about helping him. Yet often we could no longer save the poor victims".

Metal helmets – what are they for?

For the first couple of years of World War I, none of the countries provided steel helmets to their troops. Soldiers of most nations went into battle wearing cloth caps that offered no protection. German troops wore that pointy German hat, the leather Pickelhaube. The lethal head wounds inflicted by on the French led them to introduce the steel helmet in 1915.

The head injury puzzle

It was not until 1916, two years into the war that metal helmets were issued to all the British. But after they introduced metal helmets, the War Office was amazed to discover that the incidence of head injuries increased. So why should the number of head injuries increase when men wore metal helmets rather than cloth caps? The answer is that if a man arrived alive at the field hospital with a head wound, he would be listed as head wound, but if the man was dead, he would be listed as ‘dead’. Introducing metal helmets decreased the number listed as dead, but increased the number listed as head wound.

scientist 68: the crop scientist – Julian Little & products for farming (2014)
A podcast about the science of food crops. The growing world population leads to a demand to farm the land several times more effectively than we used to. But growing crops comes with risks. The farmer wants a guarantee that their efforts bear fruit. Consumers obviously want a guarantee that their food is free from harmful extras. What can be done to ensure the farmer’s crop succeeds? And what is being done to ensure our food is safe to eat? Roger Frost talks with Dr Julian Little, a crop specialist at world leading science company Bayer Crop Science in Cambridge date 26/07/2014

scientist 67: the guitarist – guitar types & quality (2014)
With many different types of guitars, we find out how much more is involved in the sound we get from various models, and whether or not this impacts on the price. Are we just paying for a brand name or the association with a particular musician? Today’s guest is Graham Buxton, a name that local music fans and musicians will recognise from a long musical pedigree. Graham has spent many years advising new musicians as to the pros and cons of each instrument. Neil asks Graham about the kind of guitars that are available. If it is perhaps true that we are paying for a brand, there is a level of quality which is behind the names which accounts towards the price. That is the case whether we’re talking about tools, foods or fashions for example.

scientist 52: the civil engineer – Robert Mair on Crossrail and Westminster (2014)
Asking someone to send you an “engineer” will conjure up all sorts of people who build and fix things. But today’s show is about civil engineers. Professor Robert Mair of the University of Cambridge Engineering Department will explain what do they do. What’s the difference between a civil engineer and a washing machine engineer? Is it that a civil engineer wears a suit? Maybe not, but you’ll hear about the civil engineering in “Crossrail”, a £15 billion project to a build train route from Reading, tunnel across London and then on to Essex and Kent. Work started five years ago and the first trains will run in 2019.
