Macrobiotus Shonaicus
''Macrobiotus shonaicus'' () is a species of tardigrade in the family Macrobiotidae. it is only known from its type locality (biology), type locality: Tsuruoka, Japan. The species description was published in 2018. The insides of their first three pairs of legs have a slight fold above their claws, and their eggs have processes whose terminal discs split off into thin filaments. Taxonomic history The species description was written by Daniel Stec, Kazuharu Arakawa, and Łukasz Michalczyk; it was published in ''PLOS One'' in February 2018. Arakawa collected ten ''M. shonaicus'' specimens in May 2016 from moss growing in his apartment building's parking lot, in Tsuruoka, Japan. The moss, ''Bryum argenteum'', was growing on a concrete surface. One pair of these tardigrades successfully reproduced in vitro, yielding an isogenic strain. The holotype, 57 paratypes, and 34 eggs were deposited at Jagiellonian University in Kraków. An additional 17 paratypes and 7 eggs were deposited at ...

Phase-contrast Microscopy
__NOTOC__ Phase-contrast microscopy (PCM) is an optical microscopy technique that converts phase shifts in light passing through a transparent specimen to brightness changes in the image. Phase shifts themselves are invisible, but become visible when shown as brightness variations. When light waves travel through a medium other than a vacuum, interaction with the medium causes the wave amplitude and phase to change in a manner dependent on properties of the medium. Changes in amplitude (brightness) arise from the scattering and absorption of light, which is often wavelength-dependent and may give rise to colors. Photographic equipment and the human eye are only sensitive to amplitude variations. Without special arrangements, phase changes are therefore invisible. Yet, phase changes often convey important information. Phase-contrast microscopy is particularly important in biology. It reveals many cellular structures that are invisible with a bright-field microscope, as exemplif ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
