Leading cause of US food-borne illness makes its own pathway through cells
...mpylobacter." Usually, material entering the cell moves to compartments called lysosomes, where an acidic mix of enzymes breaks it down. By monitoring markers for this entry pathway, Watson and Galn could watch as the microbe infected a host cell, briefly associated with the early marker protein EEA-1, an...Scientists crack the genome of the parasite causing trichomoniasis
... Viewed under the microscope Trichomonas vaginalis moves quickly; it has four undulating flagella and a tail. "It is a gassy organism," says Dr. Carlton. It has special power-generating structures called hydrogenosomes. They produce hydrogen. "So it is releasing hydrogen into the liquid media, making it fr...Scientists map air pollution using corn grown in US fields

In time, the daughter grows beyond the end of the mother to ultimately produce two microtubules, connected by the cross-linking MAP ase1p.
