Carnival of space week 14 is at Universe Today I contributed my updated article on the liberty gaseous core nuclear thermal rocket which has contains all radiation from the atmosphere but delivers 40 times more cargo than the Space shuttle. There is article about extracting oxygen from lunar soil Colony worlds talks about landing humans …
Researchers demonstrated that activating SIRT1 and injecting resveratrol, which have both been previously associated with life-span extension in lower organisms, can also prevent cognitive problems in the mice.

Startup company Ceravision Ltd. (Milton Keynes, England) has said it has invented a 50% efficient microwave-powered light bulb that is more efficient than filament (5% efficient) or fluorescent (15% efficient) lighting and with a long stable lamp life. The company said it has prototypes available for evaluation by lamp and electronics manufacturers. digg_url= ‘http://advancednano.blogspot.com/2007/07/startup-company-ceravision-has-50.html’; digg_skin …
Toronto, Canada is introducing an air pollution index that is correlated to health risk This is a good way to make the health risks of air pollution something that people can be aware of on a daily basis. If this is used globally it could help movitivate replacing or cleaning up coal and fossil fuel …
Nanoimprinting lithography (NIL) is a simple pattern transfer process that is emerging as an alternative nanopatterning technology to traditional photolithography. NIL already has been applied in various fields such as biological nanodevices, nanophotonic devices, organic electronics, and the patterning of magnetic materials. Researchers at Berkeley have taken this process one step further by demonstrating that …
The New Scientist reports progress to 3D holograms of molecules Image quality improves significantly as the number of computer processing iterations increases from 0 (left) to 500 (right) (Image: The American Physical Society) For years physicists have grappled with a kind of double vision that has made using holography difficult. The process results in an …
The efforts thus far have yielded designs for a laptop that would cost about $47; a $10 system remains the ultimate goal. Negroponte’s One Laptop Per Child Organization submitted a proposal to the Indian government under which the group would have worked to produce laptops for Indian students starting at $100. The OLPC organization has …
Pretty much all of the 2008 candidates for president are favorable to nuclear power Each of the top contenders for the Republican nomination and all but one of the major Democratic hopefuls support nuclear power to some extent. Most cite the prospect that atomic energy could help reduce climate change by supplanting power produced by …
Loss of only one of the genes, a gene encoding the protein PHA-4, negated the lifespan-enhancing effect of calorie-restriction in worms. And, when researchers undertook the opposite experiment—by overexpressing pha-4 in worms—the longevity effect was enhanced. “PHA-4 acts completely independent of insulin/IGF-1 signaling and turns out to be essential for CR-mediated longevity,” says Panowski. “We …
Space Wars by William Scott, Michael Coumatos, and William Birnes, Forge Books (April 17, 2007) describes how the first hours of World War III might play out in the year 2010. While fiction, it’s based on real-world military scenarios and technologies, dramatically highlighting the West’s vulnerability to destruction of its space-based commercial and military communications …
Researchers have developed an organic lighting device with “100 percent internal quantum efficiency” by employing newly designed host materials coupled with optimized device architecture. What’s particularly significant about the researchers’ work is that their optimized device adopts an even simpler structure than any yet reported by other research groups. “There is no waste of electricity,” …
