Digital Genome Mapping
This one is huge. Nowadays you can submit a small sample of your DNA (like saliva, hair, etc) to companies such as 23andMe who can analyze the sample and report back with all sorts of interesting and useful information about you, your ancestry, and your current and future health.
Your DNA can tell how you will respond to certain drugs, conditions you may be at risk of passing on to children, genetic flaws that could put your future health at risk, and much more. This sort of stuff has been around for a long time, but mapping a genome cost millions. Now, 23andMe will map your genome and give you a full report for under $200 – how’s that for a bargain?
