Researchers have found evidence that "marine snow"--aggregates of organic material floating in water bodies--may act as microscopic, island-like refuges for pathogens, or disease-causing organisms. This detritus may skew water sampling procedures and mathematical models used to predict the transmission of waterborne diseases to humans.

Most laboratory water purification systems contain a resistivity or conductivity meter and cell to monitor the purity level of the water. Resistivity is the reciprocal of conductivity and either may be used to inexpensively monitor the ionic purity of water.

UCLA researchers report in the April 30 edition of the journal Cell that they have imaged a virus structure at a resolution high enough to effectively "see" atoms, the first published instance of imaging biological complexes at such a resolution.

A team of scientists working at beamline 9.0.1 of the Advanced Light Source (ALS) at the U.S. Department of Energys Lawrence Berkeley National Laboratory has used x-ray diffraction microscopy to make images of whole yeast cells, achieving the highest resolution11 to 13 nanometers (billionths of a meter)ever obtained with this method for biological specimens. Their success indicates that full 3-D tomography of whole cells at equivalent resolution should soon be possible.

Agricultural Research Service (ARS) scientists are helping U.S. Nuclear Regulatory Commission (NRC) experts model the movement of radioactive materials in the soil. Their findings can be used to fine-tune the risk assessment studies that are an essential component in the development of commercial nuclear facilities.
