Scientists collaborate to assess health of global environment

...nishing capacity of services to meet human demands reflects a global problem, Mooney said. Fifteen of the 24 services the assessment considered have been degraded over the last 50 years--most notably fresh water, fisheries, air and water purification, and the regulation of climate, natural hazards and pests. ...

As a group, smokers' brain responses to drug cues remained stable regardless of the duration of time since their last cigarette, found the researchers. However, further analysis revealed that those smokers who report...
