In research funded by Sparks charity, Great Ormond Street Hospital Children's Charity and Cancer Research UK, researchers at the University of Cambridge have developed a test for blood and cerebrospinal fluid
samples that looks for a specific panel of four pieces of
short genetic
code known as microRNAs, which are found in greater quantities in malignant germ cell tumours.
Listen to some
samples, all reading the
short science fiction story, I've Written a Little
Code, by Andrew Knighton, to see which you prefer.
