For high frequency electromagnetic light waves in the frequency range of several 100,000 gigahertz (500,000 GHz corresponds to yellow light with 600 Nm wavelength), one needs very small antennas, which are not larger than a half light wave length, thus maximally 350 nanometers (1 nanometer = 1 millionth millimeter). The scientists of the DFG Heisenberg …
A magnetic space launcher is proposed by Bolonkin. If this magnetic launcher costs 50 millions of dollars, lifetime of installation is 10 year and mountain is $2 millions of dollars per year. The launcher operates 350 days and launches 100 kg payload every 30 min (This means about 5000kg/day and 1750 tons/year). Then additional cost …
Forbes has a list of other US Legislation [besides Healthcare, climate change and finance regulatory reform. Appropriations: Aside from health care reform, this will be Congress’ main task between now and December, as the Senate has only approved four of the 12 appropriations bills. Defense spending: Perhaps the most contentious of the spending bills now …
Jeff Welser Interview Here is the Jeff Welser interview by Sander Olson. Dr. Welser is the Director of the Nanoelectronics Research Initiative (NRI). The NRI was established in 2004 in order to develop post-silicon CMOS computing technologies, which will be needed by 2020 if not earlier. The NRI is hoping that a post-CMOS technology will …
WHO estimates that better use of existing preventive measures could reduce the global burden of disease by as much as 70%. 2008 World Health Report. Accelerating the improvement in lowering deaths from infectious disease. The top chart shows that acute respiratory infections, diarrhoeal disease, Malaria, HIV/Aids and Tubercolis kill about 9 million people in 2009. …

Researchers in Singapore have successfully fabricated a family of aligned one-dimensional C-curved nanoarches of different compositions by a simple and scalable method for the first time. Article in ACS Nano: A Family of Aligned C-Curved Nanoarches. The nanoarches are actually nanotubes with their extremities firmly attached to the silicon surface, thereby forming a turned letter …
In Russia, 59% of deaths in men and 33% of deaths in women between the ages of 15-54 were caused by alcohol. Most of these alcohol-attributed deaths were from alcohol poisoning, accidents, violence, or one of eight disease groups strongly related to alcohol, such as TB, pneumonia, pancreatitis or liver disease. Professor Sir Richard Peto …
The gold posts in this colorized micrograph, averaging 450 nanometers in diameter, are used to anchor individual biomolecules such as DNA for studies of their mechanical properties. The background surface is glass coated with a protein to prevent unwanted sticking. Credit: D.H. Paik/JILA Successful use of gold in optical-trapping experiments, reported in Nano Letters, could …
