This image shows a map of neural activity in the awake mouse brain, top, and pattern of brain communication when the sensory projection neurons are optically driven, bottom. The hotter colors indicate higher correlation. There are about 100 billion neurons in the human brain, and each one belongs to elaborate networks that control our behavior, …
Arxiv – High On/Off Ratio Graphene Nanoconstriction Field Effect Transistor Graphene transistors with current on/off ratios greater than 1000 could be suitable for digital electronics applications say the researchers, who now hope to increase the efficiency of their top-down fabrication process to produce integrated circuits containing NCFETs We report a method to pattern monolayer graphene …
Fox news, CNN and NBC are all projecting that the Republicans will win a majority in the House of representatives. Fox news is projecting a 60 seat gain for the Republicans. It is likely that the Democrats will keep the majority in the Senate. However, many of the Democrats ran against Obama to retain their …
The British pavillion had large fiber optic elements that made an otherworldly look at a distance. There were 72 million attendees of the Shanghai 2010 world expo. The vast majority of the attendees were from across China – visited pavilions staged by more than 240 countries and organisations. I went to the expo two weeks …
Scientists have managed to produce a small-scale version of a human liver in the laboratory using stem cells. They are the first to use human liver cells to successfully engineer miniature livers that function – at least in a laboratory setting – like human livers. The next step is to see if the livers will …

Shown in the image are depictions of (top) a conventionally calcined c-oriented silicalite-1 zeolite membrane and (bottom) an identically oriented membrane that has undergone rapid thermal processing (RTP). Red and green regions in the 3D schematics are indicative of zeolite crystal grains and defects/grain boundaries, respectively. A scanning electron microscopy (SEM) image of the membrane …
Alberta has several large scale pilot projects to perform many more oil refining and combustion steps underground and coal gasification underground. The advantages can be significantly lower costs and improved environmental effects. This site has covered the work of Petrobank to develop the THAI (Toe-to-Heel Air Injection)and CAPRI processes for upgrading oilsand bitumen underground for …
The NY Times discusses an interesting study that connects the removal of lead from gasoline with the drop in violent crime Has the Clean Air Act done more to fight crime than any other policy in American history? That is the claim of a new environmental theory of criminal behavior. In the early 1990s, a …
