Emiliania huxleyi virus 86 (EhV-86) belongs to the family Phycodnaviridae, a group of viruses that infect a wide range of freshwater and marine eukaryotic algae. Phycodnaviridae is one of the five families that belong to a large and phylogenetically

Chthamalus stellatus and C. montagui are warm-water barnacles common on rocky shores in southwest England, Ireland, and southern Europe. They are partly sympatric, with overlapping vertical and horizontal distributions. It has been suggested that the

Calcium (Ca++) and other diffusible ions cannot be preserved for x-ray microanalysis if specimens have been preserved by fixation using formaldehyde, glutaraldehyde or other fixatives. Atoms, such as Ca, are not diffusible when they are bound to some

The first successful dye-fills of Schwann cells around the split giant axon of Loligo show them to be spindle-shaped cells ca. 600 $\mu $m long and 20 $\mu $m wide lying parallel to the axonal axis. There are some 50000 Schwann cells per cm$^{2}$ of

Looking through a microscope for extended periods is not what we were designed for - it requires holding our bodies in an unnaturally rigid position. This can cause cramped muscles and strained tendons and ligaments in the head, neck, back, shoulders

A number of species of coccolithophorid phytoplankton precipitate calcite inside intracellular vesicles (coccolith vesicles). They can form vast blooms under certain conditions, and account for major fluxes of inorganic carbon (Ci) to the ocean floor

SUMMARY Tissue blocks have been plunged into a liquid coolant and the resultant ice-crystal damage is discussed. Some blocks have been frozen without apparent ice-crystal damage; they were not treated with cryo-protectants but were mounted on streaml

The suggestion that the two chaetognath speciesSagitta setosaandS. eleganswere ‘indicators’ of different water masses was first made by Meek (1928), working off Northumberland, and subsequently developed by Russell (1933, 1935, 1939) in his class

Liquid propane and similar coolants are used in the rapid freezing of biological specimens. These coolants form explosive gas mixtures with air with a 14,000-fold increase in volume over that of the liquid. The liquefied gases have high vapour pressu
