Biologists have discovered the largest bacterium ever, and you can see it with the naked eye. Researchers found the bacterium living in Caribbean mangroves. A single cell of its thread-like body, if ...

New work shows that bacteria (and probably other cells as well) don't double in mass before dividing. Instead they add a constant volume (or mass) no matter what their initial size. A small cell adds ...

The detection and inactivation of pathogenic strains of bacteria continues to be an important therapeutic goal. Hence, there is a need for materials that can bind selectively to specific ...

The study of relationships between cell size and productivity is of key importance in microbial ecology to understand which members of natural aquatic communities are responsible for the overall ...

One of the most common bacteria in the Earth, Shewanella oneidensis MR-1, influences the mobility and bioavailability of iron and environmental contaminants like lead, cobalt and arsenic. Researchers ...

Marine bacteria have important functions in oceanic biogeochemical cycles (Pomeroy et al., 2007). Through their actions, they control the fate of the fixed carbon (C) in the ecosystem (Azam et al., ...

Three aspects of size selective feeding by the scuticociliate Cyclidium glaucoma were studied in continuous cultivation systems. Firstly, grazing-induced changes in abundance, biomass, and size ...

In 2001, the FDA approved the use of capsule endoscopy, which uses a capsule size camera [1.2 inches long by 0.4 inches in diameter]. These are passive systems. There is work to make smaller robotic ...
