Are Teeth Better? Histological Characterization of Diagenesis in Archaeological Bone–Tooth Pairs and a Discussion of the Consequences for Archaeometric Sample Selection and Analyses

Teeth are often the preferred source material for isotopic and genetic assay involving ancient biomolecules. The assumption is that dental tissue preserves better due to its anatomically protected location, the enamel cap, and lower porosity compared to bone. However, this assumption has not been widely tested. Some similarities in diagenetic processes are to be expected due to similarities in structure and chemical composition of dentine and bone. This has led to the suggestion that bone can be used as an indicator of dental preservation, as a pre‐screening technique in the selection of suitable samples for biomolecular studies. Thus, direct testing of the correlation between bone and tooth preservation and diagenesis is needed. This paper reports the results of the histological characterization of diagenetic alterations within 25 human femur–tooth pairs, from a Medieval to modern (AD 1850) cemetery in Eindhoven, the Netherlands. The results showed that teeth do indeed preserve better overall, but not always, and that this was dependent on the main diagenetic factor(s) at the burial location. Furthermore, good correlations are found between the microstructural preservation of bone and teeth; similar processes of decay were observed within bone and teeth of the same individual. Overall, the study demonstrated that histological analysis of bone is useful for the identification of degradation processes that affect biomolecular preservation in skeletal material. In this way, sample selection and analytical strategies can be optimized. Copyright © 2013 John Wiley & Sons, Ltd.     

Assyrian Attitude Towards Captive Enemies: A 2700‐year‐old Paleo‐forensic Study

The Assyrians, who ruled at the height of their power between Egypt and the Persian Gulf (745–630 BC), are known from historical records to have been cruel and unrelenting towards their enemies. However, osteological evidence for this behavior is scarce. We herein present a case of an adult male skeleton, dated to the Iron Age IIB period (second half of the 8th century BC), who manifests traumatic injuries to the skull, left forearm, vertebrae, and ribs. Using modern forensic methods, the injuries were studied, and the consequences that led to these injuries reconstructed. Three possible scenarios are presented: (i) wounds inflicted during a chaotic battle; (ii) wounds caused by the chasing and capturing of a victim; and (iii) a commonly practiced violent attitude of Assyrian soldiers towards a captive combatant. Combining all the evidence at hand, the latter scenario appears more likely. This skeleton may therefore be one of the sole tangible physical evidence for the veracity of the Assyrians’ post‐battle behavior, as depicted in ancient texts and reliefs.

A perplexing document in the early history of Gilles de la Tourette Syndrome: Melotti's rendition of a "Lecture of Charcot" (including a complete translation from the Italian with commentary)

In 1885, Dr. Guilio Melotti published an Italian translation of a lecture on "Convulsive Tics with Coprolalia and Echolalia" given by Jean-Martin Charcot. Although this lecture often has been cited as an authoritative statement of Charcot's view, until now it has not been translated into English. The lecture presents a number of statements that appear nowhere else in Charcot's published corpus, including some that seem to contradict Charcot's other pronouncements on maladie des tics. Although the Melotti-Charcot lecture may portray Charcot's position accurately in many passages, the article most likely is a compilation from a variety of sources.     

Lung cancer, chronic disease epidemiology, and medicine, 1948-1964

Beginning in the early 1950s, a series of epidemiological, biochemical, pathological, and animal studies demonstrated a link between cigarette smoking and lung cancer. A number of reputable scientists challenged these findings, but for a variety of reasons, including the behavior of the tobacco industry, historians have assumed that these objections were insubstantial and disingenuous. Viewing these objections in scientific and medical perspective, however, suggests that there was a legitimate and reasonable scientific controversy over cigarette smoking and lung cancer in the 1950s and early 1960s. That controversy had important consequences. A new chronic disease epidemiology emerged, transforming the role and importance of epidemiology to medical research. This new epidemiology supplemented Koch's postulates, establishing a statistical method that allowed for linking environmental factors to the etiology of chronic diseases. The 1964 report to the surgeon general, Smoking and Health, represented the denouement and codification of these developments. This reexamination of the scientific controversy over smoking in the 1950s and early 1960s provides an important context for understanding the subsequent public relations battles between the tobacco industry and public health after 1964.
