Engineered Microbes Boost Ethanol

The yeast strain they made can tolerate ethanol concentrations as high as 18 percent–almost double the concentration that regular yeast can handle without quickly dying. In addition, the new strain makes about 20 percent more ethanol by processing more of the glucose, and it speeds up fermentation by 70 percent. So far the researchers have …

2030 Energy forecast is 50% more coal usage

Coal is projected to increase 50% in the AEO2007 reference case, particularly for electricity generation. Coal consumption is projected to increase from 22.9 quadrillion Btu (1,128 million short tons) in 2005 to more than 34 quadrillion Btu (1,772 million short tons) in 2030, with significant additions of new coal-fired generation capacity over the last decade …

Faster read and write using gallium ions for Spintronics

Spintronic memory advance: New research suggests a new route for developing high density magnetic memory chips which will not lose information when the power is switched off. For the first time data will be written and read very fast using only electrical currents. Physicist at the Universities of Bath, Bristol and Leeds have discovered a …

Reduce drag for faster and more efficient ships

The New Scientist, examines the efforts to reduce ship drag using tiny bubbles, slippery polymers and trapped sheets of air. As a ship moves through water it encounters three types of drag: wave drag, pressure drag and frictional drag. Wave resistance is mainly a problem at high speed, and can be minimised with a carefully …

Swarmanoids

Swarmanoids are a follow up to swarmbots Will initially have eye-bots, hand-bots and foot-bots Swarm robotics is inspired by the social insect metaphor, and emphasises aspects such as decentralisation of control, limited communication abilities among robots, use of local information, emergence of global behaviour, and robustness. Most current studies in swarm robotic systems have focused …
