Carnival of Space week 72 is up at twisted physics (Discovery Magazine blog.) This site contributed an update on the solar electric sail project. Colony worlds talks about creating instant roads on the moon and Mars Potentia Tenebras talks about setting bases on near earth asteroids. Check out the Carnival of Space for a lot …
Aquaculture is a major part of the worlds current and future food supply. It currently is the fastest growing food producing sector in the world. Genetically modified (GMO) fish are likely to dominate future fish farming by growing over two times faster than regular fish and being up to 30% more efficient with feed than …
Carnival of Space week 70 is up at Orbital Hub New experiments for modular space craft that would control relative position via magnetic fields. This site contributed the article on the advance in separating carbon nanotubes which seems likely to be a significant step towards space elevators. A graduate student at Cornell University set up …
This technology news roundup has imminent testing of the Vasimr plasma rocket in space, twelve dollar personal computers, ten dollar dime sized microscopes and a plant that is 250% better than corn for biofuels and twice as productive as switchgrass. (the plant has not been modified yet and genetic modifications could vastly increase yields.) Nasa …
From the EEtimes, MIT researchers have solved issues with scanning beam interference lithography and have tested at 25 nanometers and believe they can get to 12 nanometers at least. This is a big deal because it will ensure that Moore’s law to continue to improve computers for another 15 years or more. Current lithography is …
Dave Mosher at discovery.com has an excellent Carnival of Space week 62 The slideshow presentation and article layout are top notch and the content of twenty articles is excellent as well. Space Disco is one of the seven new blogs you’ll find at Discovery Space. Bad Astronomy is one of the blogs thathas moved to …
Calera is a company funded by Vinod Khosla which is trying to make concrete that pulls carbon dioxide from the air instead of emitting it. This would have a huge reduction in greenhouse gases when fully deployed. Concrete manufacturing is a primary source of carbon dioxide. For each ton of Calera concrete one ton of …
The traditional picture of how liquid water behaves on a molecular level is wrong, according to new experimental evidence collected by a collaboration of researchers from the Department of Energy’s Stanford Linear Accelerator Center (SLAC) in California, RIKEN SPring-8 synchrotron and Hiroshima University in Japan and Stockholm University in Sweden. Nilsson and colleagues probed the …
– Researchers at the University of Pennsylvania School of Medicine and collaborators are using minute, naturally occurring proteins called zinc fingers to engineer T cells to one day treat AIDS in humans. The first steps have been taken towards the goal of using modified T cells from an HIV-infected person for their own treatment. They …
Businessweek discusses Obama’s plan to increase the marginal tax rate back to the level under Bill Clinton and before the Bush tax cuts Of the 149 million households filing federal income taxes for 2006, some 3% reported income between $200,000 and $500,000; fewer than 1% claimed income above half a million dollars. The Bush administration …
Italian researchers study the problem of thermoelectricity and propose a simple microscopic mechanism for the increase of thermoelectric efficiency. Basically their theory is that thermoelectric conversion of heat into electricity can reach the Carnot limit and have some new computational modeling to guide development toward that goal and to model materials in a way that …
