Deep dives
Exploring Osteology with Dr. Westcott
Dr. Westcott, a forensic anthropologist, delves into osteology, the study of bones, and its varied applications. He discusses the intricate process of bone healing after a fracture, highlighting the roles of osteoclasts and osteoblasts in reshaping bones. His insights reveal how bones act as historical records, reflecting a person's lifestyle, age, ancestry, and health status.
Unraveling Skeleton Stories
Through examining skeletal remains, Dr. Westcott uncovers a wealth of information about individuals, including gender, age, activity patterns, and health conditions. He shares intriguing details about identifying male or female remains at a glance and how bone analysis can reveal occupation-related stresses on the skeleton.
Donating Bodies for Science and Decomposition Studies
Dr. Westcott oversees a body farm that studies decomposition rates for forensic investigations. He details the emotional aspect of handling donor remains, especially those of young individuals, emphasizing the transition from emotional attachment to scientific analysis. Dr. Westcott also discusses the significance of donating one's body to advance scientific knowledge and green burial options.
The Science Behind Decomposition
Dr. Westcott explains the scientific principles behind bone decomposition, illustrating how tuberculosis manifests in skeletons and leaves unique traces. He clarifies DNA extraction from bones, the emotional challenges of handling deceased individuals, and how studying decomposition aids forensic sciences and law enforcement investigations.
Decomposition Process and Environmental Factors
The process of decomposition varies based on environmental conditions. In Texas, a body takes about a year to completely skeletonize due to slow skin decomposition. The decomposition rate is influenced by temperature, with higher temperatures speeding up the process. There are upper and lower thresholds to decomposition, with activity levels like chemical reactions and bacterial growth impacting the timeline.
Understanding Bone Growth and Skeletal Structure
Bones provide valuable insights into an individual's history and activities. Factors like diet, antibiotics, and physical activity influence bone growth and structure. The fibula is often considered the most useless bone, primarily serving as a muscle attachment site. While tailbones are essential for muscle connections, humans lack a penile bone due to evolutionary changes.
Let's dig right into Spooktober with ... BONES. You're a steak-covered skeleton and it's nothing to fear. The amazingly kind and committed osteologist Dr. Daniel J. Wescott of Texas State University's famed Forensic Anthropology Research Center sits down -- surrounded by skulls and femurs and ribs -- and chats about how bones are formed, how they break, why they might hurt when the weather changes, what CSI gets wrong, how long it takes a body to decompose, looking for isotopes in found remains, cast iron coffins, skeleton myths, body donation, and more. Will Alie freak out, or will this exposure to hundreds of skeletons under one roof chill her out?
