I DNA Tested My Cat and She Was Not Happy About It

I was crawling around on the floor, chasing my cat, Avalanche, as she artfully wriggled away from me over and over again to gnaw at the piece of tape I had stuck to her grey and white fur. Avalanche had unwittingly become a victim of journalistic inquiry: I wanted to explore the latest fad in consumer DNA testing, genetic analysis for pets. But rather than somehow coax my cat to spit in a tube, Basepaws required that I stick a piece of tape to Avalanche’s body, then “gently” pull it off. Except it turns out that there is no way to gently rip tape off of an animal completely covered in two-inch-long fur. My cat was furious with me for hours. Read More >>

Woman Says Test Revealed Her Parents’ Fertility Doctor Was Actually Her Father

Estonia Is Taking a Page from 23andMe to Offer DNA-Based Health Advice to Citizens

From its perch on the Baltic Sea, the tiny former Soviet nation of Estonia has become an unlikely leader in all things digital. Its government has already embraced blockchain, declared Internet access a basic human right, and embarked on a massive undertaking to become a “digital society” where everything from identity to voting is digitized and linked together across one massive platform. Given this, it’s no surprise that this nation would be quick to embrace another up-and-coming technology: DNA testing. Read More >>

Dutch Police Are DNA Testing 21,500 Men to Solve a 20-Year-Old Murder

In 1986, a technique called “DNA fingerprinting” was used for the first time in a criminal investigation, when a geneticist named Alec Jeffreys realised that when DNA was extracted from cells and attached to photographic film, it developed as a sequence of bars that could uniquely identify someone. His accidental discovery helped nail the suspect in the murder of 15-year-old Dawn Ashworth. Since then, for better and for worse, DNA has become gold-standard evidence that has led to thousands of convictions. Read More >>
