By what he calls a “curious stroke of luck,” he has all of the 18th century papers of his great-great-great-great (that’s four) grandfather, including diaries, accounts, letters, and even shopping lists. In 2011, he published the story of this ancestor’s life as a social history, “The Life of a Georgian Gentleman,’ and thus, a blog was also born.

  • What blinded Mary Ingalls?

It’s easy to forget how devastating the “usual childhood diseases” of the 19th and early 20th centuries were to families. Sanitation improvements have helped tremendously.

  • Literal XX Xplainer: How we can live with two X chromosomes

    …ression of one X chromosome in each cell makes each woman a lovely mosaic of genetic expression (although not true genetic mosaicism), varying from cell to cell in whether we use genes from X chromosome 1 or from X chromosome 2. Because these gene forms can differ between the two X chromosomes, we are simply less uniform in what our X chromosome genes do than are men. An exception is men who are XXY, who also shut down one of those X chromosomes…

  • Biology Explainer: The big 4 building blocks of life–carbohydrates, fats, proteins, and nucleic acids

    …molecules themselves break down into a surprisingly small number of building blocks. The proteins that make up all of the living things on this planet and ensure their appropriate structure and smooth function consist of only 20 different kinds of building blocks. Nucleic acids, specifically DNA, are even more basic: only four different kinds of molecules provide the materials to build the countless different genetic codes that translate into all…

  • After Newtown missteps, journalists get guidelines

    …almost twice as likely to say that they don’t want to live or work near a person with mental illness if they read an article about a person with mental illness involved in a mass shooting, according to a study published March 20 in the American Journal of Psychiatry. Interestingly, this tendency is the same even if the article avoids any mention of mental illness. This may be because this link between violence and mental illness is deeply engrain…
