Navy High-Speed Vessel Swift (HSV 2) has 28,000-square-foot mission deck, the ability to traverse littoral (shallow) waters, speed in excess of 40 knots, and maneuverability that doesn’t require tugboat assistance when arriving or departing the pier and cargo space 17 times a C-17. A sustained 40+ knot speed would mean an Atlantic crossing in less …
It is important to know that Metcalfe’s law is wrong. Telecommunications is a huge business as are social networking sites and other internet systems. Proper valuation of a network is important to get correct business decisions. When you get it wrong you end up with a dot bomb. Metcalfe’s Law says that the value of …
This is a survey from IEEE Spectrum about identity theft and the new biometric technology that should be used to reduce this problem. According to data from the Aberdeen Group, Boston, the cumulative ID theft losses suffered by tens of millions of individuals and businesses worldwide registered at an estimated $221 billion in 2003. Aberdeen, …
A composite material consisting of a horse protein and metallic nanoparticles displays magnetic properties very similar to those of human brain tissue, scientists have found. The work, published in the June 20 online edition of Physical Review B, may help lead to a more thorough understanding of the magnetic behavior of brain tissue and other …
Fullerenes used to make better, more stable MRI imaging agent. Investigators from the National Cancer Institute’s Cancer Nanotechnology Platform Partnership at Virginia Commonwealth University have developed a new imaging agent that is 40 times more potent at boosting magnetic resonance imaging (MRI) signals than agents currently approved for human clinical use. Brian WangBrian Wang is …
Nano probe may open new window into cell behavior at physorg and eurekalert. Georgia Tech researchers have created a nanoscale probe, the Scanning Mass Spectrometry (SMS) probe, that can capture both the biochemical makeup and topography of complex biological objects in their normal environment — opening the door for discovery of new biomarkers and improved …
These are welcome developments as we can not see well outside of our solar system. As I have noted in my predictions if we can combine hypertelescope concepts (very large space arrays), new worlds imaging ideas (satellites that null the light from stars so that their planets can be seen) and magnetic inflation of really …
The rapid prototyping laser printing seems like an early precursor of the kind of production that we would want from a nanofactory. This technique could come top down / bottom up. Top down to 2 nanometers or less with metamaterial superlens able to focus to 1/20th of wavelength and maybe less.Bottom up with directed self …
Magnetic fields and magnetospheric plasmoids could move electrically charged bacteria from one planet to another and even to another solar system The idea that microbes could be electrically levitated into the upper atmosphere was first suggested in 1908 by chemist Svante Arrhenius, but until recently there had been no direct measurements of the strength of …
Soukoulis and his co-workers from the University of Karlsruhe, Germany, published in the May 12, 2006, issue of Science, that they have fabricated for the first time a metamaterial that has a negative index of refraction at 1.5 micrometers (1500nm). These wavelengths are microscopic and can be used in telecommunications. Soukoulis’ success moves metamaterials into …
Datamining all known possible crystal structures allows scientists to identify a short list of crystal structures for any mixture of elements whose structure is unknown. They then use quantum mechanical calculations to identify the right one. The process is now 30 to 300 times faster. Using a technique called data mining, the MIT team preloaded …
