If the result is contrary to the hypothesis, then you’ve made a discovery. —Enrico Fermi A few months after his death in 1528, Vier Bücher von menschlicher Proportion (“The Aesthetic Anatomy of Human Proportion”) by German artist Albrecht Dürer […]

Transposable elements

DNA sequencing is not static. A considerable amount of DNA jumps around from place to place. While other elements compete for representation at a given locus, transposable elements accumulate by copying themselves to new locations in the genome. Transposable elements are sequences of DNA that can move around to different positions within the genome of […]

Known to the Dutch as the “Hongerwinter,” the winter of 1944-45 saw the birth of almost 40,000 babies, each of whose vital statistics, such as name, birth date, and weight, were duly recorded by the Dutch authorities. In the 1960’s researchers began to study these now fully-grown famine survivors, and the results were shocking.

The Epigenetics of Lifespan

The beneficial effects of caloric restriction (or therapies that mimic caloric restriction) appear to exert transgenerational effects -at least in rotifers. A new study appears to implicate the enzyme catalase with the longevity benefits of caloric restriction.

Fingerprint White Lines and Gluten

Although almost everyone knows that fingerprint ridge patterns remain constant and unchanging throughout life (which is why they are so useful to law enforcement) even professionals involved in dermatoglyphics research are often unaware of the changeable nature of the actual height of the ridges themselves. There are a series of surprising correlations between changes to the height of the ridge pattern and links to gluten intolerance found in diseases such as celiac.
