Pill-size to bacteria sized robots for surgery and in-body therapies

In 2001, the FDA approved the use of capsule endoscopy, which uses a capsule size camera [1.2 inches long by 0.4 inches in diameter]. These are passive systems. There is work to make smaller robotic systems and systems that can perform more of the capabilities of regular endoscopes. These capabilities include therapeutic and diagnostic operations …

Terahertz microscope can resolve 40 nanometers

Terahertz near field nanoscope has 40 nanometer resolution. Nanoscale resolution is achieved by THz field confinement at the very tip apex to within 30 nm, which is in good agreement with full electro-dynamic calculations. Imaging semiconductor transistors, we provide first evidence of 40 nm (λ/3000) spatial resolution at 2.54 THz (wavelength λ = 118 μm) …

Free Piston Engines Versus High Efficiency Diesel Engines like Ecomotors

Free piston engines could achieve efficiencies of 50% which is almost double a regular gas combustion engine. However, new super efficient diesel engines could be even better, plus diesels would be more familiar to the market place. Some small companies are working on free piston engines and there are researchers around the world at Sandia …

Fish farming and Genetically Modified Fish for Feeding a Future World

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 …

Technology News roundup: Vasimr rocket, $12 PC, $10 microscope, better biomass

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 …

Optical lithography can go to 12 nanometers at least

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 …

Startups looking to make building green

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 …

Stanford has More Evidence for two molecular group Theory of Water

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 …
