China’s Navy modernization and fleet composition

During the past 15 years, China’s ambitious naval modernization has produced a more technologically advanced and flexible force. The PLA(N) currently possesses more than 300 surface combatants, submarines, amphibious ships, and missile-armed patrol craft. Although the overall order-of-battle has remained relatively constant in recent years, the PLA(N) is rapidly retiring legacy combatants in favor of …

Dwave quantum computers for the next few years

Dwave quantum computers at 512 qubits should run some algorithms that achieve a speed advantage I’m some cases. However, there are a lot of supercomputers and a petaflop scale machine could come down to $10 million prices in the next year. The main utility of the quantum computers will be to run unique quantum algorithms …

ReWalk robotic exoskeleton to go on sale January 2011 to help parapalegics walk

ReWalk can help paraplegics to stand and walk – using crutches for stability – when they lean forward and move their upper body in different ways. Regular usage of the device, which costs about $100,000, would prevent costly complications that often arise in people who can’t walk, including pressure sores and urinary, digestive, circulatory, and …

Carnival of Nuclear Energy 6 – the Real World and Arithmetic Confounds Nuclear Skeptics

The Sixth carnival of nuclear energy is up at NEI Nuclear Notes site This site provided the article which used energy statistics for OECD countries over time which show that solar and wind have been built far slower than nuclear energy. This shows that Mark Jacobson is wrong in his misleading looking at pieces of …

Human running speeds of 35 to 40 mph may be biologically possible

Peter Weyand and colleagues have published a paper which details how human running speeds of 35-40 mph may be biologically possible Peter Weyands estimate of the fastest speed a human can run has been covered here before (he had indicated that 45 mph is possible for a modified human shaped runner). The newly published evidence …

Argonne Labs Working to Control Casimir Force

MEMS used to detect the presence of the Casimir Force Scientists at the U.S. Department of Energy’s Argonne National Laboratory are developing a way to control the Casimir force, a quantum mechanical force which attracts objects when they are only a hundred nanometers apart. Recently Ames Lab calculated that metamaterials could be used to make …

Nanowires Go 2D and 3D and are Biocompatible

Taking nanomaterials to a new level of structural complexity, Harvard scientists have determined how to introduce kinks into arrow-straight nanowires, transforming them into zigzagging two- and three-dimensional structures with correspondingly advanced functions. Among possible applications, the authors say, the new technology could foster a new nanoscale approach to detecting electrical currents in cells and tissues. …
