Demeter's absence caused the death of crops, livestock, and eventually of the people who depended on them (later Arcadian tradition held that it was both her rage at Poseidon and her loss of her daughter caused the famine, merging the two myths). [27] Demeter washed away her anger in the River Ladon, becoming Demeter Lousia, the "bathed Demeter ...

In terms of tissue type, the body may be analyzed into water, fat, connective tissue, muscle, bone, etc. In terms of cell type, the body contains hundreds of different types of cells, but notably, the largest number of cells contained in a human body (though not the largest mass of cells) are not human cells, but bacteria residing in the normal ...
In mammalian outer hair cells, the varying receptor potential is converted to active vibrations of the cell body. This mechanical response to electrical signals is termed somatic electromotility; [13] it drives variations in the cell's length, synchronized to the incoming sound signal, and provides mechanical amplification by feedback to the traveling wave.
The Human Cell Atlas project, which started in 2016, had as one of its goals to "catalog all cell types (for example, immune cells or brain cells) and sub-types in the human body". [13] By 2018, the Human Cell Atlas description based the project on the assumption that "our characterization of the hundreds of types and subtypes of cells in the ...
They may have also used these animals' long bones to make bone tools, and additionally there are stone artefacts in each layer excavated. [ 23 ] In 1998, five child hand- and footprint impressions were discovered in a travertine unit near the Quesang hot springs in Tibet; in 2021, they were dated to 226 to 169 thousand years ago using uranium ...
Archaeologists have unravelled the mystery of a strange skeleton from Belgium consisting of bones from five people who lived 2,500 years apart. The skeleton, unearthed in the 1970s at a Roman ...
[90] [91] In bioarchaeology, the sulfur system has been used to investigate paleodiets and spatial behaviors through the analysis of hair and bone collagen. [92] Dietary proteins incorporated into living organisms tend to determine the stable isotope values of their organic tissues.
