Submarines could be made less visible to sonar using metamaterials There are still many challenges to overcome including the variability of the surrounding water and enabling lack of sonar reflection from more than one direction (ie another submarine at the same depth unable to detect but one above or below could) Brian WangBrian Wang is …
Here is a survey on status of the work around the world on Thorium nuclear fission reactors and molten salt reactors. Molten Salt reactors may be safer than current reactors and could close the nuclear fuel cycle and some designs can eliminate the longest lived nuclear waste. Molten Salt reactors potentially eliminate the need for …
A Stanford team have developed a potentially pathbreaking blood test that, according to preliminary studies, is able to identify patients with Alzheimer’s disease – an ailment that has been notoriously difficult to diagnose. Another group has determined that the prevention of pyro-glutamate A” aggregation is an important mechanism and therapeutic target for treating Alzheimers’. Brian …
Suggestions on how to optimize performance on an IQ test Let the “experts” argue about whether you can boost IQ or not, in any absolute sense. If you slept well, exercised, then sat up straight and breathed deeply as you took the test, don’t you think you would score a few points higher on an …
Until recently, the Internet2 had a theoretical limit of 10 gigabits per second, which is thousands of times faster than standard home broadband connections. By sending data using 10 different colors, or wavelengths, of light over a single cable, operators are boosting the network’s capacity to 100 Gbps. Internet2 already is planning future expansion. By …
Drexler is the one who started the idea of molecular manufacturing back in the mid-1980’s. The general focus of the Roadmap is on atomically precise technologies, not productive nanosystems. It provides merit criteria and metrics for research today. When selecting between proposals, look for atomic precision. Look for size, range of materials, other criteria that …

WiPower uses induction (magnetic coupling) to transfer power from the base station to the receiving devices. They are claiming 68% efficiency in the transfer of power and believe that they can achieve 80% efficiency. A regular power cord is 58% efficient.

A discussion of possible limitations on the power of quantum and classical computers It is a useful discussion of NP hard problems. My reaction to it is that even if his conjecture that we cannot globally solve NP hard problems is correct there is still commercial viability in improving and expanding the cases where we …
Here is an analysis of a case where a 2007 supercomputer running a 1977 algorithm would be outperformed by a 1977 personal computer running a 2007 algorithm This is also discussed here This relates to the question of getting to better and better intelligence just by speeding up the hardware. Brian WangBrian Wang is a …
