Of the nearly 100 quadrillion British thermal units of energy (BTUs) used each year in the United States, 61 quads are wasted. That is not a moral judgment, or a commentary on insufficient conservation (poor insulation, idling cars, people failing to turn off lights when they leave a room). It is, as Mara Prentiss notes, predominantly fundamental physics: the fuel is burned, but less than 50 percent performs useful work...

Prof. Xiaowei Zhuang and members of her group have devised a method of visualizing RNA molecules inside cells so that the identity, location, and abundance of more than 1,000 different RNA species can be determined at the same time. The developers of the new technology say it should be possible to scale up the approach so that tens of thousands of RNA species can be imaged and identified in a single cell.
