Reconstituting ribosomes: Shown here is a parts list for creating a synthetic, self-replicating ribosome. Proteins are shown in purple, RNA in red, and DNA in blue. The list includes 54 ribosomal proteins, as well as RNA-based enzymes involved in protein production, and other molecules that interact with ribosomes. Credit: George Church and Mike Jewett Church …
MultiAir turbocharged and downsized engines can achieve up to 25 per cent fuel economy improvement over conventional naturally aspirated engines with the same level of performance. Maximum power is increased by up to 10 per cent thanks to the adoption ofa power-orientated mechanical camshaft profile. Low RPM torque is improved by up to 15 per …
The initials for Stanford University are written in electron waves on a piece of copper and projected into a tiny hologram. Stanford researchers describe how they have created letters more than four times smaller than the IBM xenon atom arranged initials. “But in this experiment we’ve stored some 35 bits per electron to encode each …
Fruit flies and humans share most of their genes, including 70 percent of all known human disease genes. Taking advantage of this remarkable evolutionary conservation, researchers at the Salk Institute for Biological Studies transformed the fruit fly into a laboratory model for an innovative study of gliomas, the most common malignant brain tumors. Being able …
The International Herald Tribune indicates that China is taking small steps to establishing the Yuan as a regional currency. The yuan’s journey from a controlled, partially convertible currency to a liquid, regional medium of exchange will be a long one, because of the desire of the Beijing government for economic stability. In addition, Beijing has …
1. The process for getting Unit 2 of the Watts Bar nuclear plant up and running by 2012 is on track. TVA is still holding to its August 2007 estimate of $2.49 billion for total capital costs to finish the project. Construction, including work on the high- and low-pressure turbines, already is under way and …
Eric Drexler, the visionary of molecular nanotechnology and mechanosynthesis, has started a new blog Metamodern: The Trajectory of Technology. Metamodern isn’t intended to be “a blog about nanotechnology”; its scope includes broader issues involving technologies with world-changing potential. For example, looking well downstream in technology development, I will sketch the requirements for large-scale systems able …
The AMD Firestream setup from Aprius could be better with eight of the $1499 boards ($12000 plus some amont for the 4U box and backplane.) It will outperform the Nvidia setup and be out in about 4-6 months. Of course Nvidia could go through another rev from its current setup. The FireStream 9270 uses a …
SiCortex, maker of energy-efficient high-productivity computing (HPC) platforms, today announced that it has doubled the price/performance metric of its entire product line. This breakthrough is the result of increased processor speed, advancements to system software and leading-edge compilers. SiCortex computers scale from 72 to 5,832 processors running Linux and other open-source codes, in packages ranging …
Above is a chart of the debt ratios in 1996 and 2006 for OECD countries. Some people are overly focused on the deficit in the United States and believe that the US dollar would collapse and be replaced by the Euro or the Yen. As can be seen in the chart the European countries are …
Natural Gas production is going up by a lot in the United States. This was noted at Peak Oil Debunked about a month ago. The peak oil people such as Mike Ruppert and Matt Simmons were saying in 2003 and since then that natural gas production was heading for a sharp decline. Now even some …
