Ratting out disease: How animals are detecting disease - and other threats to life

...DNA-based technique, which is supported by the World Health Organization, performs strongly on both variables. And in an ideal world, most clinics would use LED microscopy or GeneXpert. But these techniques are expensive and slow. A rat, which costs $6,500 to train, can rattle through 100 samples in 20 minutes. A GeneXpert device, which costs $17,000, takes around two...

...DNA (short for deoxyribonucleic acid – you do not need to remember this!). The DNA contains the code for genes, written in chemical ‘letters’. Genes are the templates for proteins – that is, they contain instructions for putting together protein molecules from building blocks called amino acids. (You read about an amino acid, tryptophan, in Section 4.3) Protein...
