Potential contaminant pathways from hydraulically fractured shale to aquifers.

Hydraulic fracturing of deep shale beds to develop natural gas has caused concern regarding the potential for various forms of water pollution. Two potential pathways-advective transport through bulk media and preferential flow through fractures-could allow the transport of contaminants from the fractured shale to aquifers. There is substantial geologic evidence that natural vertical flow drives contaminants, mostly brine, to near the surface from deep evaporite sources.

Modifying the effects of cerebral palsy: the Gregg Mozgala story.

In response to a news report of the rehabilitation of a New York-based dancer/actor with cerebral palsy, to the point where a ballet performance was scheduled, it was determined that a report based on the individuals involved would be commissioned. The resulting reports from the choreographer responsible for the rehabilitation exercises, and the dancer, were circulated to an interdisciplinary selection of physical medicine experts, for commentary as to what clinicians might learn from the case, and what mechanisms might be involved.
