Stem Cell Research
Recipe for Induced Pluripotent Stem Cells Just Got Clearer

Dennis Normile
Science 14 August 2009: 803.
A clutch of five letters published online this week shows that p53 hinders the generation of induced pluripotent stem (iPS) cells. The work suggests ways to control the formation of iPS cells, although that capability will have to be used judiciously because p53 helps ensure the fitness of generated cells.

Aircraft Designers Shoot for Savings on the Wing

Daniel Clery
Science 14 August 2009: 810.
Commercial aircraft have become steadily more fuel-efficient by using better engines and reducing the drag and weight of the planes themselves. But efficiency increases beyond that may require a radical change in the shape of the aircraft, which carries enormous risks for manufacturers and airlines. Summary »|   Full Text »|   PDF »|  

Energy Efficiency
Making Use of Excess Heat

Dan Charles
Science 14 August 2009: 811.
The single biggest opportunity to increase the "energy productivity" of American industry is to make use of heat that would otherwise be thrown away. One way to do that is via cogeneration, or "combined heat and power," a technique that is more than a century old but newly fashionable. Summary »|   Full Text »|   PDF »|
