Science Promises Cleaner Biofuels; Greens Wary

'Understanding the risks' of genetically engineered microbes is essential, some say

(Newser) - The future of alternative energy may lie with genetically engineered microbes that can efficiently convert sugar, or even sewage, into fuel, Yale Environment 360 reports. Small biotechs are using the tools of “synthetic biology” to create organisms that produce a range of carbon fuels without the extra energy expended... More »

Transistors May Migrate to Paper

Circuit-carrying cellulose undercuts silicon on price

(Newser) - The future of electronics may be etched on paper, reports the Economist. Researchers have found a cheaper, easier way to make transistors using cellulose, paper’s key ingredient. Paper could soon replace silicon as a surface on which to mount transistors, which control the flow of electric currents and power... More »

Scientists Roll Out Paper Batteries

We're hoping for fold-able cell phones

(Newser) - Scientists have come up with a paper-like substance that can act as a power source, Scientific American reports. The thin, flexible substance—composed of cellulose, carbon nanotubes, and liquid salts—can be used as both a battery and a supercapacitor, which can deliver quick bursts of high power. What's more,... More »
