Many have two lobes of bright material, resembling arcs of a circle, connected by a bridge, somewhat resembling the letter Z.
The researchers claim some groupings are reminiscent of dividing bacteria, and argue that their textured surface, the presence of lacy material resembling the mineralized biofilm produced by bacteria, and an occasional fibril-like filament also suggest "possible bacteria in Nakhla".
In the March 2005 issue of Science, the paleontologist Mary Higby Schweitzer and her team announced the discovery of flexible material resembling actual soft tissue inside a 68-million-year-old Tyrannosaurus rex leg bone from the Hell Creek Formation in Montana.
Later, Bud Harrelson smoothed out some of the surface, an absorbent material resembling sand that had been spread around the infield near second base.
The memorial sculpture was prescribed in form and was made in wood or from the trunks of tree fern, an easily worked material resembling compacted pine needles.
This idea is supported by histological sections of such aggregates (Figure 1B) showing dark cells, presumably D. caveatum cells, filled with phagosomes containing material resembling the majority of cells in the aggregates, the D. discoideum cells.
In simulated body fluid (SBF), a biomimetic mineral layer is formed on the material resembling the function of BAGs [ 9].
Strikingly, it also labels, strongly, an apical crescent and an apex-associated material, resembling the localization of the secretory v-snare SynA [49] at the apical plasma membrane crescent, where exocytosis predominates, and at the Spitzenkörper, where post-Golgi carriers accumulate [41].
The discharge/charge behavior of the material resembles that of high specific capacity non-graphitic carbon.
