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 …

IBM has new phase change memory. Can be 500 times faster than Flash

IBM has made germanium-antimony-tellurium phase change memory. The advantage of the new material, according to the scientists, is that it can be used to create switches over 500 times faster than today’s flash chips. Moreover, the prototype switch developed by the scientists is just 3 nanometers high by 20 nanometers wide, offering the promise that …

Hydrogen economy less efficient than electron economy

According to the laws of physics it would be more efficient to have our energy based upon electricity instead of hydrogen Hydrogen as an energy carrier would be less efficient than electricity. In a sustainable energy future, electricity will become the prime energy carrier. We now have to focus our research on electricity storage, electric …

Near term solar sails

Centauri dreams has a couple of interesting articles about near term solar sails. Gregory Benford (University of California at Irvine) and his brother James (Microwave Sciences) have solar sail with a painted polymer layer that desorp from the sail as extra propulsion The solar sail could be deployed in low Earth orbit by conventional rocket. …

Carbon nanotube muscles created 100 times stronger than natural muscle

Carbon nanotube muscle 100 times stronger than normal muscle has been created. Spinning carbon nanotubes into yarn a fraction of the width of a human hair, researchers have developed artificial muscles that exert 100 times the force, per area, of natural muscle. This is according to Ray Baughman, director of the Nanotech Institute at the …

DNA logic gates designed and created

California Institute of Technology researchers successfully combined up to 12 different DNA logic gates in five cascading levels, although the process takes hours, they report in the December 8 Science. A group of so-called logic gates performs each operation. In the A AND C operation, for example, one gate would consist of strand B intertwined …

Plasmons – bridging optics and electronics

New light physics with plasmons that could bridge light, matter and electronics. Plasmon computers could operate at 100 Terahertz – 1000 terahertz or 20,000 to 200,000 times faster than mainstream computer chips. Part of what I think is the growing trend of greater control of all information, light, energy, matter and magnetism. (ILEMM) Two-dimensional light, …
