Most people are usually referring to their gin and tonic, but in August 1961 we were more concerned with fish. that the UK鈥檚 fishmongers weren鈥檛 heeding the adage, and fish were warming up too rapidly in their displays. We reported on 3 August that the spoilage rate of cod increases with temperature at a constant rate between its freezing point and 25掳C and pointed out that flavour becomes more unpalatable with every degree of warming. We recommended refrigerated slabs in addition to the usual ice piled around the display. And who knew that the freezing point of a cod was -1掳C?

We learned more about low temperatures in our . 鈥淔rozen nerves lead to speedy recovery,鈥� we announced. Instead of administering drugs for pain relief after surgery, surgeons at Colindale hospital in London had discovered that freezing nerves around the surgery site 鈥� a process they called cryoanalgesia 鈥� removed nearly all the pain people experience post-surgery. It was especially effective in chest surgery where ribs have to be parted to allow the surgeon access to the lungs or heart. Patients who were frequently in agony following surgery could move, sit up and 鈥� critically 鈥� cough to removed phlegm from recovering lungs.

Unfortunately, Siberian mammoths didn鈥檛 receive the same benefits from freezing temperatures. On 13 August 1994, we reported that mammoths living on the Siberian steppes had died of malnutrition, thanks to the cold and a lack of vegetation. Ironically, the cold had preserved their bodies, allowing researchers to date them as being between 10,000 and 12,000 years old. Gilles Pacaud of the French National Museum of Natural History told New Scientist that the animals 鈥渨ere using up more calories feeding themselves than they were ingesting from the vegetation鈥�.
