" But what if our experiences of being bullied did a lot more than just saddle us with some serious psychological baggage? Well, to answer that question, a group of researchers from the UK and Canada decided to study sets of monozygotic “identical” twins from the age of five. Besides having identical DNA, each twin pair in the study, up until that point, had never been bullied. You’ll be glad to know that these researchers were not allowed to traumatize their subjects, unlike how the Swiss mice were handled. Instead, they let other children do their scientific dirty work. After patiently waiting for a few years, the scientists revisited the twins where only one of the pair had been bullied. When they dropped back into their lives, they found the following: present now, at the age of 12, was a striking epigenetic difference that was not there when the children were five years old. The researchers found significant changes only in the twin who was bullied. This means, in no uncertain genetic terms, that bullying isn’t just risky in terms of self-harming tendencies for youth and adolescents; it actually changes how our genes work and how they shape our lives, and likely what we pass along to future generations.

" Initially, Mendel’s work on the mating habits of mice seemed simple enough. But eventually, to Schaffgotsch, it simply went too far.3 For starters, the caged rodents in Mendel’s spacious, stone-floored quarters gave off a stench that Schaffgotsch found incompatible with the tidy life expected of a monk of the Augustinian order. Then there was the sex. Mendel, who like all of the monks at St. Thomas had taken a vow of consecrated chastity, seemed obsessively interested in how the furry little creatures were getting it on. That, Schaffgotsch figured, was beyond the pale. So the dour bishop ordered the inquisitive young monk to shut down his little mouse brothel. If Mendel were, as he professed, purely interested in how traits move from one generation of living creatures to the next, he’d have to be content with something less titillating. Something like peas. "
