Concerns about dwindling fossil fuel resources, current levels of petroleum consumption, and growing pressure to shift to more sustainable energy sources are among many factors prompting the transition from our current energy infrastructure to one that uses less carbon and requires the efficient conversion of energy.

Ants more rational than humans
In a study released online on July 22 in the journal Proceedings of the Royal Society: Biological Sciences, researchers at Arizona State University and Princeton University show that ants can accomplish a task more rationally than our -- multimodal, egg-headed, tool-using, bipedal, opposing-thumbed -- selves.

Improved air quality during Beijing Olympics could inform pollution-curbing policies
The air in Beijing during the 2008 Olympics was cleaner than the previous year's, due to aggressive efforts by the Chinese government to curtail traffic, increase emissions standards and halt construction in preparation for the games, according to a Cornell study.

Pandemic could overwhelm critical care beds in England, especially children's units
Experts in intensive care and anesthesia have predicted that the current swine flu pandemic could overwhelm critical care beds and ventilators in England, with hospitals on the southeast coast, and in the southwest, east of England and East Midlands, being worst hit.
