Carnegie Mellon engineers devise new process to improve energy efficiency of ethanol production

...ess by using a multi-column system together with a network for energy recovery that ultimately reduces the consumption of steam, a major energy component in the production of corn-based ethanol. "This new design reduces the manufacturing cost for producing ethanol by 11 percent, from $1.61 ...

OHSU studies of technology for healthy aging get boost

...e new monitoring technologies will be tested. This network of 20 to 30 elder-inhabited residences throughout the Portland area will be outfitted with a basic set of devices for continuous, remote assessment of activity and computer use, in which fluctuations can mean problems with cognition and mobility.

Gene knockouts reveal FoxOs' vital functions in cancer defense, health of stem cells

...s regulate genes in the complicated cell signaling network known as PI3K-AKT, or simply PI3K. Scientists have discovered that PI3K signaling is intimately involved in fundamental cell processes such as metabolism, aging, and protecting the body against cancer. The PI3K circuit has been found to be disrupted ...

Complex channels

The messages passed in a neuronal network can target something like 100 billion nerve cells in the brain alone. These, in turn communicate with millions of other cells and organs in the body. How, then, do whole cascades of events trigger responses that are highly specific, quick and precise...
