Vivianite crystals are often found inside fossil shells, such as those of bivalves and gastropods, or attached to fossil bone. Vivianite can also appear on the iron coffins or on the corpses of humans as a result of a chemical reaction of the decomposing body with the iron enclosure.
Technicians preparing a body for cryopreservation in 1985. Cryonics (from Greek: κρύος kryos, meaning "cold") is the low-temperature freezing (usually at −196 °C or −320.8 °F or 77.1 K) and storage of human remains in the hope that resurrection may be possible in the future.
Osteoblasts produce an advanced type of bone matrix consisting of dense, irregular crystals of hydroxyapatite, packed around the collagen ropes. [27] This is a strong composite material that allows the skeleton to be shaped mainly as hollow tubes. Reducing the long bones to tubes reduces weight while maintaining strength.
Myoglobin sketch Alpha helix. 1958 – Myoglobin was the very first crystal structure of a protein molecule. [2] Myoglobin cradles an iron-containing heme group that reversibly binds oxygen for use in powering muscle fibers, and those first crystals were of myoglobin from the sperm whale, whose muscles need copious oxygen storage for deep dives.
DNA analysis confirmed the bone fragments were from humans and also that some were linked to the same person or a family member. Tests of animal bones found nearby suggest that the climate was ...
DNA recovered from bones discovered in 8-meter-deep cave dirt is shaking up what we know about some of the earliest modern humans.
Biomineralization, biologically controlled mineralization, occurs when crystal morphology, growth, composition, and location are completely controlled by the cellular processes of a specific organism. Examples include the shells of invertebrates, such as molluscs and brachiopods. Additionally, the mineralization of collagen provides crucial ...
In 1870, a local woodcarver was tasked with artistically arranging the bones. He created the famous chandelier, bells in the chapel and a coat of arms of the Schwarzenberg noble family.
