Viagra and CRISPR
Viagra鈥檚 effect on men was discovered by accident after a clinical trial for a heart disease with some surprising side-effects. Here鈥檚 how it happened.
Viagra鈥檚 effects on men were first discovered as an unexpected side-effect during trials for a medication meant to help patients with a heart condition. CRISPR cas鈥� 9 is now a tool that can be used to modify and replace genes 鈥� but it was first noted as a random collection of genes. In the first of three episodes about the genius of accidents in science, Professor Adam Hart explores how, sometimes, the results you鈥檙e looking for are not as important as those that appear unexpectedly.
