New Form of Brain Communication Identified

University of Minnesota

Communication among glial cells--once regarded as just "glue" for the brain--has been identified in intact retinal tissue by researchers at the University of Minnesota. The discovery is a step forward in understanding the function of these cells, which play a role in multiple sclerosis and Parkinson's disease, as well as in regulating the transmission of impulses along nerve fibers and regenerating injured or severed nerves.

Key Issues in the Air Quality Debate

Resources for the Future (RFF)

As Congress begins to consider the Environmental Protection Agency's (EPA) proposals to tighten standards for two major air pollutants, Resources for the Future today releases a briefing paper on the key issues in the clean air debate. It describes EPA's proposed new rules for ground-level ozone and particulate matter, both of which have been linked to adverse effects on human health, and discusses the major policy questions that the proposals raise.

Emission Of CFC Replacements To The Atmosphere

American Chemical Society (ACS)

The hydrochlorofluorocarbons (HCFCs) and hydrofluorocarbons (HFCs) used to replace the chlorofluorocarbons (CFCs) banned by the Montreal Protocol have low or no potential to deplete ozone in the stratosphere, but they may contribute to climatic change, says Dr. Garry D. Hayman of the National Environmental Technology Centre in Oxfordshire, United Kingdom.

Human Cell Mutagens In Los Angeles Air

American Chemical Society (ACS)

Mutagens have long been known to be present in urban air, but their detection and potency has mostly been measured with a bacterial test. However, extrapolating the observed mutagenic effects from bacteria to humans continually leads to questions about the relevance of bacterial assays. New research represents the first time a human cell mutation assay has been applied to an atmospheric particle monitoring network.
