New technique shows promise for dramatic miniaturization of metamaterials and negative index of refraction of -700, one hundred times larger than before

In a vacuum, light travels so fast that it would circle the Earth more than seven times within the blink of an eye. When light propagates through matter, however, it slows by a factor typically less than 5. This factor, called the refractive index, is positive in naturally occurring materials, and it causes light to …

Micro-drones: The new face of cutting-edge warfare

New Scientist – Drones are getting smaller and smarter, able to navigate and identify targets without GPS or human operators. Micro-aerial vehicles (MAVs) with uncanny navigation and real-time mapping capabilities could soon be zipping through indoor and outdoor spaces, running reconnaissance missions that others cannot. They would allow soldiers to look over hills, inside buildings …

Adaptable and Effective Mitigation for Nuclear Accidents and other Situations

While I have been slamming what I think is faulty nuclear energy and safety analysis by Mark Jacobson at Stanford University, I do believe that it is reasonable and necessary to make energy safer. Efforts and money should be spent to mitigate air pollution from power plants, construction activity, vehicles and industry. There should be …

Nanoscale scaffolds and stem cells show promise in cartilage repair

Johns Hopkins tissue engineers have used tiny, artificial fiber scaffolds thousands of times smaller than a human hair to help coax stem cells into developing into cartilage, the shock-absorbing lining of elbows and knees that often wears thin from injury or age. Investigators have produced an important component of cartilage in both laboratory and animal …

Current Limits of Human Strength

One aspect of transhumanism is to exceed current human limits in various aspects of performance, intelligence, longevity and health. The New Yorker has a lengthy article about Brian Shaw and the history of Strongmen Competitions and the curretn limits of human strength. It wasn’t until 1953 that the first five-hundred-pound bench press was done. Today, …

Solving Exascale Power problems will mean gigascale power for toys and megascale for heart monitors

1. EETimes – By about 2018, engineers are expected to create an exascale supercomputer—capable of a 1,000-fold performance improvement compared with today’s state-of-the-art petaflop systems. If engineers can use new technology to create an exascale system that consumes only 20 MW of power, the same technology can also be used to dramatically lower the power …
